    [0001] VEHICLE INTERIOR CABIN LIGHTING ASSEMBLY Embodiments of the present invention generally relate to lighting assemblies for use within an interior cabin of a vehicle, such as an airplane commercial, and more particularly lighting assemblies that can direct light to multiple areas within an interior cabin of a vehicle. Commercial aircraft include an interior cabin that can be divided into many sections. A cockpit is usually separated from a passenger cabin, which can include a first class section, a business class section, and an economy class section. The passenger cabin may also include one or more work areas for flight personnel, such as galleys, which may include food and beverage storage structures. One or more aisles pass through the passenger cabin and connect each of the passenger sections to one or more passageways to one or more doors of the aircraft.
    [0002] Luminaires are used to illuminate various areas inside a commercial aircraft. For example, fixtures are attached to a ceiling portion and concealed. The luminaires are used to illuminate portions of the ceiling, walls, luggage racks, and / or the like within a cabin of the aircraft. With the introduction of light-emitting diode (LED) -based luminaires, the space of the interior cabin can be illuminated with light of various colors. Some airlines take advantage of this ability by using different colored lights to enhance their brand. For example, a particular airline may illuminate areas above baggage lockers of certain colors that are associated with the air carrier.
    [0003] In addition, LED-based luminaires allow custom lighting scenes inside the cabin. For example, known systems include multiple luminaires that are used to mimic natural lighting, such as a sunrise or sunset, or a theatrical scene inside the aircraft. In general, each luminaire directs light in a single direction, which is defined by an optical element of the luminaire. To illuminate different areas inside an aircraft, multiple luminaires are used. As another option, a single luminaire 3032022 can be mechanically moved inside the aircraft to direct light to a different location. However, the limited space inside an aircraft may limit or prevent a luminaire from being moved. In addition, known luminaires include light emitters that are aligned with respect to a central longitudinal axis of each luminaire. The current interior interior aircraft cabin lighting is incapable of producing convincing transverse lighting effects (for example, transverse relative to a central longitudinal axis of a luminaire) due to the fact that the light emitters are oriented around from, and along, the longitudinal axis. Also, in various settings, the light emitted from the LEDs along the central longitudinal axis can be prevented from reaching a desired area, for example by a ceiling panel, a portion of a luggage rack, or Accordingly, there is a need for a versatile and adaptable lighting assembly that can be used within an interior space of a vehicle. Some embodiments of the present invention provide an illumination assembly configured to be positioned within an internal cab of a vehicle. The lighting assembly may include a housing defining an internal lighting chamber, and a lens attached to the interior of the internal lighting chamber.
    [0004] The lens includes a central longitudinal axis. At least one luminescent channel is fixed inside the housing. The luminescent channel (s) is offset from the central longitudinal axis. The at least one luminescent channel may include a first luminescent channel offset from the central longitudinal axis in a first area, and a second luminescent channel offset from the central longitudinal axis in a second area that is different from the first zone. The first luminescent channel is configured to produce a first light beam that passes through the lens and is directed to a first location (such as a location on a ceiling, wall, or the like of the internal cab of the vehicle), and the second Luminescent channel 30 is configured to produce a second light beam that passes through the lens and is directed to a second location. At least a portion of the second location is separated and distinct from the first location. In at least one embodiment, each of the first and second luminescent channels 3032022 includes a plurality of light-emitting diodes (LEDs). The LEDs of the first and second luminescent channels, which are configured to emit light of the same color, may be grouped into luminescent clusters, for example. The first and second luminescent channels may be configured to be activated (e.g., initially lit) in a staggered manner. For example, the first luminescent channel is activated at first moments, and the second luminescent channel is activated at second moments that are different from the first moments. In at least one embodiment, the first and second luminescent channels are configured to be in a state turned on at different times.
    [0005] For example, the first luminescent channel may be in the on state at first instants, and the second luminescent channel may be in the on state at second times that are different from the first instants. The lighting assembly may also include an luminescent channel in the axis that is aligned with the central longitudinal axis. The lighting assembly may also include a printed circuit board including a central processing unit. The luminescent channel (s) can be mounted on the printed circuit board. The lens may include a modified cylindrical shape with a first portion having a curvature different from that of a second portion. The lens 20 may be a converging lens. Some embodiments of the present invention provide a system for controlling lighting within an interior cabin of a vehicle. The system may include an illumination assembly configured to be positioned within an internal cab of a vehicle, and a user interface that is configured to program and control the illumination assembly. The user interface may include a touch screen display that includes a channel selection area and a color selection area. In at least one embodiment, the color selection area includes a color ring and a color picker. Some embodiments of the present invention provide a vehicle 30 which may include an interior booth configured to house one or more individuals, and at least one lighting assembly positioned within the interior booth. The vehicle may also include a user interface that is configured to program and control the lighting assembly.

The foregoing summary description, as well as the following detailed description of certain embodiments, will be better understood when read in conjunction with the accompanying drawings. As used herein, an element or a step, indicated in the singular and preceded by the word "a" or "an" must be understood as not excluding the plural of the elements or steps, unless expressly indicated. such an exclusion. In addition, references to "an embodiment" are not intended to be construed to preclude the existence of additional embodiments that also incorporate the features indicated.
    [0011] In addition, unless explicitly stated otherwise, embodiments "comprising" or "possessing" an element or a plurality of elements having a particular property may include additional elements not having this property. Some embodiments of the present invention provide an illumination assembly that may include one or more luminescent channels that may be offset from a central longitudinal axis, such as that of a lens of the illumination assembly. The lighting assembly may include a housing that retains multiple luminescent channels and a singular lens. Embodiments of the present invention are configured to emit light that can be directed toward, and adjusted to, different areas in a consistent and efficient manner. The luminescent channels and the lens are arranged to create multiple beams that can overlap and produce a consistent output. Some embodiments of the present invention provide a lighting assembly that may include one or more luminescent channels that include multiple light emitters, such as LEDs, a printed circuit board, a housing, and a lens, which has a primary or central longitudinal axis. The light emitters may include at least one cluster of multiple LEDs that emit the same light color. The LEDs in the cluster may be variably offset relative to the primary longitudinal axis of the lens. A plurality of LED clusters that emit different light colors can be located proximal to each other. Embodiments of the present invention are configured to provide condensed or otherwise lens-modified lighting, transverse to the bins and very easy to control, within a cabin of a vehicle, such as an aircraft. Light emitted from the illumination assembly can be directed to multiple locations with only one singular lens, via multiple LEDs offset from the primary or central longitudinal axis of the lens, by example. Thus, the lighting assembly reduces the total weight of a lighting system (in the past, multiple luminaires were used to produce light in different areas), and can be fixed inside spaces. confined vehicle. Embodiments of the present invention provide a lighting assembly that can produce millions of colors at various locations within an interior space of a vehicle. The color combination can be controlled with respect to a side area (due to the shifted nature of the light emitters relative to the lens), and a longitudinal area (since additional light emitters can be positioned over a length of 20 degrees). a portion of the vehicle). For example, each lighting assembly can be used to provide wavy patterns or transitions in the lighting, provide thematic lighting, branding lighting, and the like. Figure 1 illustrates a perspective view of a lighting assembly 100, according to an embodiment of the present invention. The illumination assembly may include a housing 102 which includes a base 104 connected to vertical sidewalls 106. An inner illumination chamber 108 is defined between the base 104 and the sidewalls 106. Retaining clips 110 may be used to secure the lighting assembly 100 to a structure, such as a ceiling, a bin reinforcement plate, a personal service unit, or a wall within an internal cabin of a vehicle. Each retaining clip 110 may include a rigid lath 112 connected to opposing side teeth 114. Inner surfaces of the side teeth 114 may include pawls 116 which are configured to snap-fit to a ridge 118 which extends toward externally from each side wall 106. In this manner, the retaining clips 110 may be snap-fastened to the housing 102. The right batten 112 may be attached to the structure, for example through one or several fasteners, for example. More or less staples 110 than those shown may be used. Alternatively, various other clips, various other fasteners, brackets, and / or the like may be used to secure the lighting assembly 100 to the structure. A printed circuit board 120 is held firmly within the internal illumination chamber 108. The circuit board 120 may include one or more processors, drivers, conductive tracks, modules (eg, stored in one or more memories), and various other components that are used to control the operation of the lighting assembly 100. Multiple light emitters are supported on the circuit board 120. One or more cables 122 route electrical wires to the board printed circuit 120 and are configured to supply electrical power to the illumination assembly 100. A lens 124 is attached to the interior of the internal illumination chamber 108 above the printed circuit board. 120 (as shown in Figure 1). The printed circuit board 120 is disposed between the lens 124 and the base 104 of the housing 102. The lens 124 may extend a length of the internal illumination chamber 108. The lens 124 may be formed of a material transparent or semi-transparent, such as glass, clear plastic, or the like. As shown, the lighting assembly 100 may include a singular lens 124.
    [0012] Figure 2 illustrates a top plan view of the lighting assembly 100, in accordance with one embodiment of the present invention. As noted, the printed circuit board 120 supports a plurality of light emitters, such as LEDs 126, groups of which can be aligned together in luminescent channels. For example, although many LEDs 126 are shown in FIGS. 2 and 3, separate and distinct groups of LEDs 126 may provide separate and distinct luminescent channels. Alternatively, the light emitters may be various other luminescent devices, such as incandescent or fluorescent light bulbs. A first linearly aligned group of LEDs extending linearly along the printed circuit board 120 forms a first luminescent channel 128, which is aligned with a central or primary longitudinal axis 129 of the lens 124. For example, Central axes extending from each LED 126 of the first luminescent channel 128 and are normal to a top surface of the circuit board 120 intersect the central longitudinal axis 129. A second linearly aligned group of LEDs 126 extending linearly along the printed circuit board 120 forms a second luminescent channel 130 which is parallel to, but offset from, the central longitudinal axis 129. For example, central axes, which extend from each 10 LEDs 126 of the second luminescent channel 130 and are normal to an upper surface of the printed circuit board 120, do not intersect the central longitudinal axis 129. As is r 2, the second luminescent channel 130 is shifted with respect to a first side of the central longitudinal axis 129. A third group of linearly aligned LEDs 126 extending linearly along the printed circuit board 120 form a third luminescent channel. 132 which is parallel to, but offset from, the central longitudinal axis 129, opposite to the second luminescent channel 130. As shown, the third luminescent channel 130 is offset from a second side (opposite the first side) of the central longitudinal axis 129.
    [0013] A central processing unit (CPU) 136 may be attached to the printed circuit board 120. The CPU 136 may be or include any computer device, memory, module, component, or the like, which is configured to control the operation of the 100. FIG. 3 illustrates a close-up top view of LEDs 140, 142, 144, 146, and 148 of the lighting assembly 100, in accordance with one embodiment of the present invention. . Each cluster 140, 142, 144, 146, and 148 may include an LED 126 from each luminescent channel 128, 130, and 132 that is configured to emit light at a particular color. For example, the cluster 140 may be configured to emit red light, the cluster 142 may be configured to emit green light, the cluster 144 may be configured to emit blue light, the cluster 146 may be configured to emit cold white light, and the cluster 148 may be configured to emit warm white light. As shown, the centers 150 of each LED of a cluster may form a line 152 which is inclined with respect to the central longitudinal axis 129. The LED 126 of each luminescent channel 130 is above the center line 130. central longitudinal axis 129, while the LED 126 of the luminescent channel 128 is on the central longitudinal axis 129, and the LED 126 of the luminescent channel 132 is below the central longitudinal axis 129. Each line 152 may be oriented at an angle θ relative to the central longitudinal axis 129. For example, the angle θ may be between 15 ° and 45 °. Alternatively, the angle may be greater than or less than 15 ° -45 °. For example, the line 152 of each cluster 140, 142, 144, 146, and 148 may be perpendicular to the central longitudinal axis 129. The clusters 140, 142, 144, 146, 10 and 148 may be inclined, as is shown, in order to adjust all the LEDs 126 inside the internal illumination chamber 108 of the housing 102. In operation, the LEDs 126 of each luminescent channel 128, 130, and 132 may emit light to form a light. desired color of emitted light. For example, light from each LED 126 may vary in intensity and duration to emit light at a desired hue, brightness, and the like. For example, the LED 126 in the cluster 140 (red) and the LED 126 in the cluster 144 (blue) can simultaneously produce light, while the other LEDs 126 are in an off state, thereby producing violet light. Since the luminescent channels 130 and 132 are offset from the central longitudinal axis 129, the illumination assembly 100 can produce and direct light to three separate and distinct locations (within a control cabin). a vehicle, for example) through the use of the singular lens 124. For example, the luminescent channel 130 may emit a first light beam which is directed to a first location, the luminescent channel 128 may emit 25 a second beam of light which is directed to a second location, and the luminescent channel 132 may emit a third beam of light which is directed to a third location. The three locations may be separate and distinct from each other. Alternatively, portions of at least two of the locations may overlap. The luminescent channels 128, 130, and 132 may emit separate and distinct light beams at the same or different times. For example, when one of the luminescent channels 128, 130, or 132 is in an active or on state, the other luminescent channels 128, 130, or 132 may be in a disabled or off state. As used in the foregoing, the term "activate" means initially start or turn on a luminescent channel in an active state, while the term "disable" means to turn off a luminescent channel. For example, a luminescent channel is activated in an active state in which it emits light, while the luminescent channel is turned off by being turned off in a disabled state in which it does not emit light. The luminescent channels 128, 130, and 132 provide three separate and distinct illumination devices within the common illumination assembly 100, which may also include only the singular lens 124. Each luminescent channel 128, 130, and 132 emits light which is directed to three separate and distinct locations, through the use of the singular lens 124. As shown, the center 150 of each LED 126 of luminescent channel 128 is disposed on and along a line 133 which is aligned with the central longitudinal axis 129 of the lens 124. Namely, a plane extending between the line 133 and the central longitudinal axis 129 may be normal or perpendicular to a upper planar surface of the circuit board 120. The center 150 of each LED 126 of the luminescent channel 130 is disposed on and along a line 135 which is offset from the line 133. Similarly, the center 150 of each LED 126 of luminescent channel 132 is disposed on and along a line 137 which is offset from line 133, opposite line 135. Therefore, luminescent channels 130 and 132 are off-set with respect to the central longitudinal axis 129. The luminescent channels 130 and 132 are out of the axis with respect to the central longitudinal axis 129. The luminescent channels 130 and 132 may be symmetrical or asymmetrical with respect to the longitudinal axis 129. For example, the luminescent channel 130 may be shifted with respect to the longitudinal axis 129 at a distance different from that of the luminescent channel 132 relative to the longitudinal axis 129. FIG. 4 illustrates an end view of FIG. the lighting assembly 100, according to an embodiment of the present invention. The lens 124 may include lateral attachment protuberances 160 that extend outwardly from a main body 162. The fastening protrusions 160 may be vanes, panels, or the like that are attached to the reciprocal troughs 163 of supports 165 of side walls 106.
    [0014] The main body 162 of the lens 124 may have a modified cylindrical shape. A first portion or lower portion 164 (i.e., the portion near the printed circuit board 120) of the main body 162 may have an eccentricity and / or curvature that may exceed that of a second or upper portion 166. A radius 168 (extending from the central longitudinal axis 129 to an outer surface of the upper portion 166) is a first distance. A radius 170 (extending from the central longitudinal axis 129 to an outer surface of the lower portion 164) is a second distance. The second distance may exceed the first distance. The shape of the lens 124 allows a light beam 10 produced from the central luminescent channel, in the axis 128, to pass out of the lens 124 parallel to a lateral or optical axis 171 of the lens 124 (the axis lateral 171 being perpendicular to the longitudinal axis 129). At the same time, the shape of the lens 124 allows beams of light produced from off-axis off-axis luminescent channels 130 and 132 to pass out of the lens 124 in an inclined direction that is not parallel to the lateral axis 171. As shown, the light emitted from the lighting assembly 100, when all the luminescent channels 128, 130, and 132 are active or in the on state, forms a beam converge 180 which can converge at a focal point 182 (or any point beyond the lens 124) and expands outwardly therefrom.
    [0015] As the light beam 180 converges at the focal point 182 and expands outwardly therefrom, the width of the light beam 180 is reduced when it is emitted from the lighting assembly 100 towards the focal point. The reduced width of the light beam 180 towards the focal point when emitted from the lighting assembly 100 allows the lighting assembly to be used in confined spaces in which barriers would otherwise block transmission of light. For example, a barrier 183 having a narrow opening 185 would otherwise block at least a portion of a light beam that is as wide as the lens 124. However, the reduced width of the light beam 180 at the focal point 182 allows the beam of light to be transmitted out through the narrow opening 185 in an unobstructed (or slightly shackled) manner, and to expand and spread outward away from the focal point 182. In in short, the shape of the lens 124 produces a convergent light beam that can pass without obstruction with more efficiency and / or less loss through narrow or tight spaces. Figure 5 illustrates an end view of the lighting assembly 100 emitting three separate beams of light, in accordance with an embodiment of the present invention. As shown, the centrally located luminescent lumen channel 128 emits a first beam 190 which passes through lens 124 and is emitted outwardly therefrom in a straight, linear, parallel direction The luminescent lumen, off the axis 130, emits a second beam 192 which is normal to an upper surface of the printed circuit board 120 (before it encounters the lens 124). When the second beam 192 moves through the lens 124, however, the upper portion 166 inwardly inclines the second beam 192 toward the lateral axis 171 to intersect the lateral axis 171, and moves away, outwardly thereof to an opposite side from the location at which the luminescent channel 130 initially generated the second beam 192. Thus, while the light beam 192 is generated by the luminescent channel 130 on the left side (with respect to FIG. 5) of the lighting assembly 100, the light beam 192 is directed towards a location which is to the right of the light channel 130.
    [0016] Conversely, the luminescent channel out of the axis 132 emits a third beam 194 which is normal to an upper surface of the circuit board 120 (before encountering the lens 124). When the third beam 194 moves through the lens 124, however, the upper portion 166 inwardly inclines the third beam 194 toward the lateral axis 171 to intersect the lateral axis 171, and departs outwardly thereof to an opposite side from where the luminescent channel 132 originally generated the third beam 194. Thus, while the light beam 194 is generated by the luminescent channel 132 on the right side (with respect to FIG. 5) of the lighting assembly 100, the light beam 194 is directed towards an area which is on the left of the light channel 130. In this way, the singular lens 124 can be used to direct emitted light from each luminescent channel 128, 130, and 132 to three separate and distinct locations. For example, the light emitted from the luminescent channel 128 is directed to a central location 200, while light emitted from the luminescent channels 130 and 132 is directed to offset locations 202 and 204, respectively. Each of the luminescent channels 128, 130, and 132 may be active at the same time or at approximately the same time to produce the three light beams 190, 192, and 194 at the same time at the three separate and distinct locations 200, 202, and 204. Optionally, less than all the luminescent channels 128, 130, and 132 may be active at the same time. Referring to FIGS. 1 to 5, light produced from each of the luminescent channels 128, 130, and 132 may be sequenced to provide a variety of illumination effects, such as lighting movement effects. For example, light can be emitted from the luminescent channel 130 at a first instant, which can then be turned off at a second time subsequent to the first moment, when light can be emitted from the luminescent channel 128. The luminescent 128 may then be turned off at a third instant subsequent to the second instant, when light can be emitted from the luminescent channel 132, thereby producing a visual effect of light moving through a surface. In such an application, the times at which the luminescent channels 128, 130, and 132 are in the off state are long enough for a person to perceive that they are, in fact, turned off. The duration of the deactivation of a luminescent channel 128, 130, and 132, and the activation of the following luminescent channel 128, 130, and 132 in the sequence may be long enough to result in an overlay, which may provide a transition mixture that smooths a movement effect. The CPU 136 may operate the luminescent channels 128, 130, and 132 so that they are not all in the on state at the same time. For example, the luminescent channel 128 may be in a lit state during a first period, in which the luminescent channels 130 and 132 are in an off state. During a second period, which is subsequent to the first period, only the luminescent channel 130 may be in a lit state, whereas during a third period, which is subsequent to the second period, only the luminescent channel 132 may be in a state on. The LEDs 126 of each luminescent channel 128, 130, and 132 may cycle between the on and off states (e.g., pulse duration modulation) faster than a person can see them, and, thus, may not seem to blink. Although each luminescent channel 128, 130, and 132 (and / or LED clusters) can be activated at separate and distinct times (i.e., phased activation times), the luminescent channels 128, 130, and 132 (and or the LED cluster) may remain in a lit state after activation. Figure 6 illustrates waveforms 220, 222, and 224 of three separate and distinct luminescent channels over time (t), in accordance with one embodiment of the present invention. As shown, the waveform 220 includes a plurality of activation times 226 and deactivation times 228. Similarly, the waveform 222 includes a plurality of activation times 230. and disabling times 232, while waveform 224 includes a plurality of activation times 234 and disabling times 236. Each luminescent channel is in a lit state from a time of activation until a deactivation time. Conversely, each luminescent channel is in an off state from a deactivation time to an activation time. The on state can be a duty cycle of 50%, for example, while the off state can be a duty cycle of 0%. In a variant, the lit state may be greater than or less than 50%, but in any case greater than 0%. As shown, the activation times 226, 230, and 234 are staggered. The activation times 226, 230, and 234 do not occur at the same time. Rather, each activation instant 226, 230, and 234 occurs at a separate and distinct time. Although the activation times are staggered, two or more of the luminescent channels may be in a lit state for at least a portion of the time after they are initially activated.
    [0017] Referring to FIGS. 1 to 6, the activation of each luminescent channel 128, 130, and 132 may be staggered to minimize or otherwise reduce the electromagnetic interference (EMI) generated by the illumination assembly 100. CPU 136 can cause drivers functionally connected to each of the luminescent channels 128, 130, and 132 to turn on at separate and distinct times, so that all luminescent channels 128, 130, and 132 are not active. at the same time. In addition, CPU 136 may operate subchannels or LED arrays 126 in a similar fashion. By minimizing or reducing the timing of ignition or activation of each luminescent channel 128, 130, and 132, and / or clusters, the EMI signature of the illumination assembly 100 is reduced.

It should be understood that the interior booth 830 may include more or fewer sections than shown. For example, the internal booth 830 may not include a first class section, and may include more or fewer office sections than is shown. Each of the sections may be separated by a car transition zone 846, which may include curtain assemblies between structural features (such as boundaries, height traps, or the like) within aisles 848. Fig. 15 illustrates an axial cross-sectional view of a portion of an inner cabin 900 of an aircraft, according to an embodiment of the present invention. The inner cabin 900 may be defined, in part, by a ceiling 902 and a side wall 904. A luggage rack 906 may be pivotally or slidably attached to the side wall 904. A lighting assembly 910, such as any of those described with respect to Figures 1 to 12, is fixed inside a trough 912 above the luggage rack 906 and below the ceiling 902 and / or inwardly of the side wall 904. The chute 912 provides a small area in which the lighting assembly 910 can be attached. Since the illumination assembly 910 may include multiple luminescent channels, at least one of which may be off-axis, the illumination assembly 910 is capable of emitting light at different locations 920 and 922. Additional lighting packages can be used throughout the cabin, and at different locations. Particularly, with prior known lighting systems, when an LED emits light on a luggage rack through an aisle, the uppermost portion closest to the luggage rack tends to be well lit, while the lower portion of the luggage rack (because it is farther away and moves away with a slanting LED) tends to be darker. As a result, a shadow typically existed towards the bottom of the luggage rack. In stark contrast, embodiments of the present invention provide lighting assemblies that eliminate, minimize, or otherwise reduce such shadows, because the lighting assemblies are configured to control brightness in multiple directions. In addition, the lighting assemblies are capable of projecting bright, uniform light onto lower portions of luggage racks, which, as noted, were likely to be shadowed when illuminated by lighting systems. known prior lighting. In order for prior art systems to reduce such shadows, multiple lighting housings must be used, which increase weight and cost, and may not be able to fit within a particular confined space.

The channel select area 1006 provides a plurality of channel buttons 1008, 1010, and 1012 that a user can use (e.g. by touching and staying in place) to select a particular luminescent display luminescent channel. For example, each channel button 1008, 1010, and 1012 is associated with a separate and distinct luminescent channel. After a particular channel is selected through the channel selection area 1006, an individual can then select a particular emitted light color via a color selection area 1014. 1014 color selection may include a 1016 color ring, which can display all available colors (for example, the ROY-GB-IV color spectrum). A color selector 1018 may be located within the color ring 1016. The color selector 1018 may include a movable selection member 1020 (such as a highlighted area, a mark, or the like) that an individual can use with a finger. The individual can then rotate the color selector 1018 through a selection member 1020 to a desired color of the color ring 1016. Once the color is selected, the individual can then adjust the brightness, saturation, and the like by moving a finger over an inner area of the color selector 1018. A selected color area 1021 represents the color as currently selected. The display 1004 may also include a cold white setting slider 1022 and a warm white setting slider 1024. The sliders 1022 and 1024 allow the individual to adjust the intensity, brightness, and / or the like of white 25 cold and warm by sliding a finger on them. The display 1004 may also include a mode slip zone 1026 that allows an individual to switch between various lighting modes.
