    description
    FLOOR LAMP
    The invention relates to a floor lamp with a lamp base, a lamp-mast element, a first light source for generating a first light, which is at least substantially discharged into the upper half-space and a second light source for generating a second light, the at least is discharged substantially into the lower half-space.
    Such a floor lamp in the form of an indoor work light is known from the prior art, in which a lamp head is arranged at the upper end region of the lamp mast element, in which the first light source is located. The first light is emitted upwards via the luminaire head and is provided for the purpose of producing "indirect lighting" by illuminating a ceiling area of a corresponding room located above the floor lamp. The second light source is also located in the lamp head and the second light emitted into the lower half-space is provided for generating a "direct illumination", in particular for illuminating a workstation.
    This floor lamp is generally very sensitive to dust; Moreover, it consists of relatively many components. In addition, the possibilities of designing the external appearance of the floor lamp are limited by the lamp head.
    The invention has for its object to provide a corresponding improved floor lamp, in particular with reference to the above-mentioned disadvantages.
    This object is achieved according to the invention with the object mentioned in the independent claim. Particular embodiments of the invention are indicated in the dependent claims.
    According to the invention, a floor lamp is provided which has a lamp base, a lamp post member having an upper end portion, a first light source for generating a first light, which is at least substantially discharged into the upper half-space and a second light source for generating a second light which is emitted at least substantially into the lower half-space. In this case, the first light source is arranged in the luminaire base and the luminaire mast element is designed as a light guide which directs the first light from the first light source to the upper end region of the mast element, wherein the second light source is arranged in the luminaire mast element.
    Due to the design of the lamp-mast element as a light guide can be achieved that the first light is emitted through an upper portion of the floor lamp, but the first light source is arranged in the light socket. As a result, and by the arrangement of the second light source in the luminaire mast element, the upper region of the floor lamp can be made particularly small-scale. This is advantageous with respect to the dust sensitivity of the floor lamp. Moreover, this considerably improves the possibilities with regard to the design of the external appearance of the floor lamp. In addition, the arrangement of the first light source in the luminaire socket with respect to the dissipation of heat is advantageous; For example, the light socket itself act as a heat sink.
    Preferably, the lamp-mast element is hollow along its longitudinal extent, in particular tubular or designed as a hollow cylinder. In this way, a particularly effective conduction of the first light upwards is made possible and, moreover, the second light source can be arranged particularly suitably in the hollow region.
    Preferably, the design is such that the second light is passed through an area of the lamp-mast element passing through to the outside, in particular in the lower half-space. In this way, a direct illumination, for example, a workplace can be particularly suitable effect.
    Preferably, the floor lamp further comprises a mast attachment element, which is arranged from above on the upper end portion of the lamp mast element. Thus, in particular, a suitable protection of the luminaire mast element can be effected.
    Preferably, the mast attachment element has an optical element for influencing the first light, in particular in the form of a reflector. In this way, it can be achieved that the first light is emitted particularly suitably in a desired solid angle range for producing an indirect illumination.
    Preferably, this is the mast attachment element designed such that a first portion of the first light passing through the mast attachment element is passed vertically upward and a second portion of the first light is deflected by the optical element such that it obliquely above is delivered.
    Preferably, the mast attachment element on a transparent protective cover, which is arranged covering the lighting mast element. In this way, the risk of dust deposition or contamination of the upper end region of the luminaire mast element and of the optical element for influencing the first light can be kept particularly low.
    Preferably, the floor lamp further comprises a rod-like holding element for holding the second light source, wherein the holding element is attached to the mast attachment element. Thus, it can be achieved that the second light source with the aid of the mast attachment element relative to the lamp mast element can be moved or set in a certain position.
    Preferably, the floor lamp further comprises a fixed to the holding element optical element for influencing the second light, in particular in the form of at least one funnel-shaped reflector. This makes it possible to effect a suitable steering of the second light, in particular for producing a direct illumination.
    Preferably, a cable for powering the second light source is arranged in the holding element, wherein the rod-shaped holding element preferably extends down to or into the lamp socket. This makes the power supply of the second light source particularly inconspicuous. Preferably, the mast attachment element is rotatably mounted relative to the lamp mast element. In particular, the second light source can be brought into a specific rotational position in a particularly simple manner relative to the luminaire mast element.
    Preferably, an operating device for the second light source is arranged in the lamp socket. This is advantageous with regard to a reduced space requirement within the luminaire mast element. Preferably, an operating device for the first light source in the lamp socket is arranged. Overall, this is advantageous with respect to the possibilities of the external appearance of the floor lamp.
    Preferably, the floor lamp also has a, serving to control the first light source and / or second light source sensor. Functionally and structurally advantageous, the sensor can be arranged in the interior of the luminaire mast element.
    The invention will be explained in more detail below with reference to an embodiment and with reference to the drawings. 1 shows a perspective sketch of a floor lamp according to the invention, FIG. 2 shows a schematic cross-sectional sketch through the luminaire base, [0022] FIG. 3 shows a perspective sketch of an upper area of the floor lamp and [0023 ] Fig. 4 is a corresponding schematic cross-sectional sketch.
    In Fig. 1, a floor lamp according to the invention is schematically outlined in perspective. The floor lamp - here also referred to for short as lamp - has a luminaire
    Socket 1 on - here also referred to below as Socket 1. It is envisaged that the lamp is set to operate on the base 1 and the base 1 thereby forms the only footprint of the lamp.
    Furthermore, the lamp comprises a lamp-mast element 2, hereinafter referred to as mast 2 for short. The mast 2 has an upper end region 21. In particular, the design may be such that the mast 2 from the base 1 extends vertically upwards. The mast 2 can serve in particular as a housing or housing part of the lamp.
    Furthermore, the lamp comprises a first light source 4 for generating a first light which is emitted at least substantially in the upper half-space. As indicated by dashed lines in Fig. 1, the first light source 4 is arranged in the base 1.
    As shown by way of example in FIG. 4, in which a schematic cross-sectional sketch of an upper region of the luminaire is sketched, the luminaire furthermore comprises a second light source 5 for generating a second light, which is emitted at least substantially into the lower half-space , The second light source 5 is arranged in the mast 2, preferably in an upper part of the mast 2.
    The mast 2 is designed as a light guide and passes the first light generated by the first light source 4 to the upper end portion 21 of the mast 2. In this way, in particular the possibilities for designing the upper portion of the lamp are improved overall.
    Fig. 3 shows a perspective sketch of the upper portion of the lamp. Preferably, the mast 2 is hollow along its longitudinal extent, in particular tubular or hollow cylindrical. As in the example shown the case, the mast 2 can be shaped like a profile and thereby have a circular cross-section.
    Fig. 2 shows a schematic cross section through the base 1. In the example shown, the mast 2 extends with its profile axis P vertically upwards. The mast 2 in this case comprises a, in particular normal to the profile axis P trained lower end wall surface 22 and - as in Fig. 4 denotes a, in particular normal to the profile axis P formed upper end wall surface 23, and a particular circular cylindrical side surface 24 extending upwards extends to the upper end-side wall surface 23 and down to the lower end-side wall surface 22. The lower end-side wall surface 22 and the upper end-side wall surface 23 accordingly each have a ring shape.
    The mast 2 can thus be designed very homogeneous; In particular, the design is such that the mast 2 as such has no element which serves to generate the second light.
    The mast 2 may extend with its lower end into the socket 1 in. In the base 1, the first light generated by the first light source 4 is coupled from below into the mast 1. For this purpose, the first light source 4 can have a circuit board 41 with light sources 42, which are arranged correspondingly circular to the annular shape of the lower end wall surface 22 of the mast 2; In particular, the lighting means 42 may be LEDs (LED: light-emitting diode). The LEDs 42 thus emit their light into the lower end wall surface 22 of the mast 2.
    The mast 2 then passes on the basis of its optical fiber function, the first light in particular by total reflection within its material up to the upper end portion 21 of the mast 2. Furthermore, the first light passes through the upper frontal wall surface 23 again from the mast. 2 out.
    As indicated in FIG. 4 with an exemplary light beam L2, the design is preferably such that the second light generated by the second light source 5 is emitted outwardly through a region of the mast 2. As a result of the configuration shown, it is possible to achieve that the second light can pass through the relevant area of the mast 2 at least substantially unhindered. Preferably, the design is such that the mast 2 for the delivery of the second light has no further optical function.
    As sketched by way of example in Fig. 4, the lamp further comprises a mast attachment element 3, hereinafter referred to briefly as essay 3, which is arranged from above on the upper end portion 21 of the mast 2. In the example shown, the attachment 3 has an optical element 6 for influencing the first light, in particular in the form of a reflector. The optical element 6 forms, so to speak, a secondary optic for the first light.
    In this case, the attachment 3 is preferably designed such that - as indicated by an exemplary light beam L11 - a first portion of the first light passing through the essay 3 is transmitted vertically upward and - as indicated by an exemplary light beam L12 - a second portion of the first light is deflected by the optical element 6 so as to be discharged obliquely upward. The first portion L11 of the light is thus emitted vertically upwards and the second portion L12 obliquely laterally upward, so that in this way a total ceiling area, for example, above the luminaire can be illuminated over a large area and an indirect illumination is thereby produced.
    In the example shown, the optical element 6 comprises an annular, slightly outwardly curved reflector element having a concave reflection surface 61, on which the second portion L12 of the first light is reflected. As shown by way of example in FIG. 4, the annular reflector element is preferably arranged directly adjacent to the upper end wall surface 23 of the mast 2. In particular, the reflection surface 61 is formed axially symmetrical, the axis of symmetry coinciding with the profile axis of the mast 2.
    However, the annular reflection element does not completely cover the upper end wall surface 23 of the mast 2 with its reflection surface 61, so that the mentioned first portion L11 of the first light radiates vertically upward without interaction with the reflection surface 61.
    In other words, therefore, a part of the first light, which is emitted upwards rather in the outer edge region of the mast 2, continue to radiate upward past the reflection surface 61 and, in the example shown below, is substantially perpendicular to the luminaire delivered at the top. Another part of the first light, which is emitted further upwards, is deflected at the reflection surface 61 and here also released from the luminaire into the upper half-space, but obliquely laterally upwards.
    As is apparent, for example, from Figures 3 and 4, the attachment 3 further preferably has a transparent protective cover 7, which is arranged covering the mast 2. By the protective hood 7 can be achieved in particular that the mast 2, in particular its upper end wall surface 23 is protected.
    Due to the transparent design of the protective hood 7, the delivery of the first light is practically not impeded or at least not materially. As indicated by the exemplary light beams in Fig. 4, both the first portion of the first light L11, and the second portion of the first light L12 can enforce the protective cover 7 accordingly. Preferably, the guard 7 has a circular cylindrical outer wall 71, with which it surrounds the mast 2 closed in a ring from above. In this case, the protective hood 7 preferably adjoins the mast 2 with its outer wall 71 preferably with respect to a space-saving design.
    In the example shown, a cylindrical reflecting surface 62 is further formed by the optical element 6, which is circular cylindrical about the axis of symmetry or the profile axis P and which adjoins above the concave reflection surface 61. In this case, this circular-cylindrical reflection surface 62 does not extend laterally beyond the upper edge of the concave-shaped reflection surface with respect to the axis of symmetry. By the cylindrical reflection surface 62 can be achieved that any incident on them light rays are reflected at her, and are given laterally obliquely laterally upwards. This is advantageous with respect to the efficiency of the light output.
    Furthermore, preferably, the lamp further comprises a rod-like support member 8 for supporting the second light source 5, wherein the holding member 8 is fixed to the attachment 3. In the example shown, the holding element 8 extends along the axis of symmetry within the mast 2, at least in an upper region of the mast 2.
    Preferably, an optical element 9 is attached to the support member 8 for influencing the second light. In the example shown the case, the optical element 9 comprises at least one funnel-shaped reflector. Alternatively, the optical element 9 may also comprise at least one lens element. Preferably, the optical element 9 is arranged completely inside the mast 2.
    The at least one funnel-shaped reflector preferably has a main axis, which is oriented obliquely downwards inclined, so that the second light - as indicated in Fig. 4 by the light beam L2 - is accordingly discharged obliquely down.
    In the example shown, the second light source 5 comprises a plurality, for example five light emitting areas, which are arranged forming a vertical row on the holding element 8, wherein each of the light emitting areas is assigned a funnel-shaped reflector. Each light emitting area can have at least one LED.
    The output of the second light takes place with respect to the profile axis P and the axis of symmetry not radially in all directions, but only within a radial sector. By means of the at least one funnel-shaped reflector, a corresponding limitation of the second light can advantageously be achieved.
    Preferably, the attachment 3 is rotatably mounted relative to the mast 2. Thus, the lateral radiation direction of the second light can be adjusted by turning the attachment 3 as needed. For this purpose, in particular, the holding element 8 rotatably connected to the attachment 3. In the example shown, the retaining element 8 is attached to the optical element 6.
    Preferably, a cable for power supply and / or control of the second light source 5 is arranged to extend in the interior of the holding element 8. In particular, the holding element 8 may be designed to be hollow along its longitudinal extension, wherein the cable is arranged to extend in the cavity.
    Further preferably, the cable extends downwardly into the base 1. For this purpose, the holding element 8 may extend advantageously down to or into the base 1 (not sketched in Fig. 2).
    This is particularly advantageous if, as in the example shown the case, an operating device 10, for example in the form of a converter or driver for the second light source 5 is arranged in the base 1. Furthermore, a corresponding operating device 11 for the first light source 4 in the base 1 is also advantageously arranged. The arrangement of the operating devices 10, 11 in the base 1, the design possibilities of the lamp are improved, in particular with respect to the design of the upper portion of the lamp. In addition, the arrangement of the first light source 4 and the operating devices 10, 11 in the base 1 with respect to the achievement of the required heat dissipation is advantageous. In particular, the base 1 can be made in particular solid from a good heat-conducting material, so that it itself serves as a suitable heat sink or at least has a heat sink function.
    In order to achieve a suitable rotation of the attachment 3 in relation to the mast despite the cable, the cable can be placed within the attachment 3, for example within the optical element 6 in a loop. In order to prevent the attachment from turning back a little when set in a certain rotational position due to the rigidity of the cable, the design may be such that there is a corresponding frictional engagement between the attachment 3 and the mast 2.
    Further advantageously, a stop for the rotation of the attachment 3 may be provided so that over-rotation can be prevented.
    Furthermore, the luminaire may preferably have a sensor 12 serving to control the first light source 4 and / or the second light source 5, wherein the sensor 12 is preferably arranged in the mast 2. For example, the sensor 12 may be attached to the holding element 8. In this way, the sensor 12 can rotate accordingly.
    For example, with the aid of the sensor 12, an automated activation of the first light source 4 and / or the second light source 5 may be provided.
    In this context, it can alternatively also be provided that the attachment 3 is constructed with at least two concentric annular layers (not shown in the figures) which can be rotated individually and independently of one another, one of the annular layers rotating with the second light source 5 is connected and another of the annular layers with the sensor 12. Thus, the second light source 5 and the sensor 12 can be set independently.
