    [0001] The present invention relates to an installation element, in particular to an installation element for electrically connecting an electronic component to control gear of a luminaire. Background of the Invention
    [0002] Emergency lighting plays a vital role in security systems for modern property management, and is an important facility of industrial and public buildings that is closely related to both personal safety and building safety. The importance of emergency lighting increases as population density increases, such as from accelerated urbanization, which increases security risk.
    [0003] An emergency lighting system is configured to provide lighting to ensure that people are safely evacuated from a building when the general lighting system has failed and is unable to operate normally.
    [0004] A first type of an emergency lighting system is known as a 'maintained' system, a block diagram of an example of which is shown in Figure 1 (Prior Art). Emergency lighting system 101 is configured to operate in a normal situation and in an emergency (power cut situation). Emergency lighting system 101 has a first live input L, a second live input L', and a neutral input N. The first live input L is a switched live input. The switched live input L is fed into the general lighting supply that drives the general lighting load in a normal situation. The switched live input L is typically connected to a wall switch of a building, which is provided to allow the power to lighting in the building to be selectively cut and restored through manual operation thereof by a tenant of the building. The second live input L' is a permanent live input. The permanent live input L' is from a primary power entry point of the building and is not made accessible for turning off and on by tenants of the building in a normal situation. Instead, the permanent live input L' is fed into an emergency lighting supply comprising a battery arrangement configured to be charged during a normal situation. In the event of a power cut situation, the battery arrangement discharges to a DC-DC converter arranged to generate a suitable current to drive the general lighting load.
    [0005] A second type of an emergency lighting system is known as a 'non-maintained' system, a block diagram of an example of which is shown in Figure 2 (Prior Art). Emergency lighting system 201 has a single live input L' and a neutral input N. The single live input L' is a permanent live input. The permanent live input L' is fed into an emergency lighting supply comprising a battery arrangement configured to be charged during a normal situation and to drive an emergency lighting load in the event of a power cut situation.
    [0006] Current emergency lighting systems include an LED indicator, which is typically green in standard systems or dual-colour of green and red for systems having self-testing functionality. In a standard system, the green LED indicator is always on unless there is a power cut or the battery arrangement of the emergency lighting supply is unplugged. This helps an installer or operative to identify the position and the status of the emergency lighting system. In a self-testing system, the LED indicator is normally green but changes to red to report a fault, and can flash at one of a plurality of different speeds, each speed associated with a different fault, to indicate a reason for reporting a fault.
    [0007] It is known for dedicated emergency luminaires, which are usually of the non-maintained type, to be provided with an LED indicator that is incorporated in the product during original manufacture.
    [0008] However, there are numerous applications in which a general lighting system is to be converted to a maintained emergency system through the addition of an emergency conversion module. Although the general lighting system may conveniently include a type of luminaire that features a pre-installed LED indicator that is wired to a connector ready for connection to an emergency conversion module, in many other cases an external LED indicator is required to be installed next to a luminaire, on the same mounting surface, via a separate fixing.
    [0009] In the scenario of converting a standard ceiling-mount Class III LED luminaire (LED panel and LED downlight etc.) into a maintained emergency light using an emergency conversion module, installing the required external LED indicator commonly involves forming a new opening near the luminaire, fitting the LED indicator into the opening and securing the LED indicator in position using clips or another fixing, and then wiring the LED indicator to the emergency conversion module. This process is complicated and time-consuming and can be detrimental to the appearance of the installation.
    [0010] It is therefore desirable to improve the installation of an emergency LED indicator.
    [0011] Daylight harvesting lighting is increasingly being used in pursuit of reducing energy usage. Daylight harvesting luminaires are commonly used near windows or other areas in buildings such as offices and schools where it most likely that there will be sufficient sunlight during the day time to allow luminaires provided for a particular space to be dimmed while still achieving an acceptable level of illumination in that area.
    [0012] A daylight harvesting luminaire comprises a light sensor and a daylight harvesting driver in addition to a light source. The light sensor is usually placed alongside the luminaire, at a suitable position to detect the environmental light level. Signals from the light sensor are provided to the daylight harvesting driver, which operates to decrease or increase the level of illumination from the light source until a predetermined light output, associated with a desired brightness, is achieved. However, installing the light sensor at an appropriate site requires additional work to be carried out to create a suitable aperture for receiving the light sensor and additional fixings to be used to secure the light sensor in place.
    [0013] It is therefore desirable to improve the installation of a daylight harvesting light sensor.
    [0014] It is an object of the present invention to provide improvements in the installation of a peripheral device for a luminaire. Summary of the Invention

    [0031] Example embodiments are described below in sufficient detail to enable those of ordinary skill in the art to embody and implement the apparatus, systems and processes described herein.
    [0032] A schematic of an example of a maintained emergency lighting system 101 according to the prior art is shown in Figure 1 , and a schematic of an example of a non-maintained emergency lighting system 201 according to the prior art is shown in Figure 2 .
    [0033] Current emergency lighting systems use an LED indicator by a luminaire, for indicating a normal situation. The fitting of this electronic component next to a luminaire, such as during the conversion of a general lighting system to an emergency light system, is inconvenient, time-consuming and can be detrimental to the aesthetic appearance of the overall installation.
    [0034] Current daylight harvesting system require a light sensor to be installed alongside a luminaire, for detecting the level of ambient light. The fitting of this electronic component is similarly inconvenient, time-consuming and can be detrimental to the aesthetic appearance of the overall installation.
    [0035] It is an object of the present invention to provide improvements in the installation of a peripheral device for a luminaire.
    [0036] An installation element 301, according to a first embodiment, is shown in Figures 3 to 6 . As will be described in further detail, the installation element 301 is suitable for connecting an electronic component to control gear of a luminaire. The installation element 301 is illustrated in Figures 7 to 12 in a first example application in which the installation element 301 is used to connect an LED indicator to an LED downlight, and is illustrated in Figures 7 to 12 in a second example application in which the installation element 301 is used to connect an LED indicator connected to an LED panel.
    [0037] Referring to Figures 3 to 6 , and initially to Figure 3 , installation element 301 comprises a base portion 302. The base portion 302 supports a printed circuit 303. An electronic component 304 is supported by a first region 305 of the base portion 302. An electrical connector device 306 is supported by a second region 307 of the base portion 302. A securing arrangement, indicated at 308, is supported by a third region 309 of the base portion 302.
    [0038] The second region 307 of the base portion 302 is spaced from the first region 305 of the base portion 302. The electrical connector device 306 is electrically connected to the electronic component 304. The securing arrangement 308 is attachable to a luminaire (not shown in Figures 3 to 6 ). The electrical connector device 307 is electrically connectable to control gear of a luminaire (not shown in Figures 3 to 6 ).
    [0039] The third region 309 of the base portion 302 is separate from the second region 307 of the base portion 302. Hence, the securing arrangement, indicated at 308, is supported by a region 309 of the base portion 302 that is separate from the region 307 of the base portion 302 that the electrical connector device 306 is supported by.
    [0040] The base portion 302 is flexible to allow the base portion 302 to be manipulated into a condition in which the first region 305 and the second region 307 extend in different planes.
    [0041] The base portion 302 has a length direction, indicated by arrow L, and a width direction, indicated by arrow W. According to the illustrated example, the base portion 302 is substantially planar. Preferably, the base portion 302 is a pliable substrate. In a preferred example, the printed circuit 303 is a flexible printed circuit.
    [0042] A first face 310 of the installation element 301 is shown in plan view in Figure 3 , and a second face 401 of the installation element 301 is shown in plan view in Figure 4 .
    [0043] In this example, the first and second faces 310, 401 correspond to opposite sides of the substantially planar base portion 302.
    [0044] The base portion 302 is shown in Figures 3 to 6 in a generally flat condition, in which the first region 305 and the second region 307 extend generally in the same plane. According to this example, along the length direction L, the third region 309 is disposed between the first region 305 and the second region 307, and when the base portion 302 is in the generally flat condition, the first region 305, second region 307 and the third region 309 extend generally in the same plane.
    [0045] Preferably, the base portion 302 is manipulatable into a condition in which the first region 305 extends in a first plane and the second region 307 extends in a second plane that is substantially perpendicular to the first plane. According to this example, the base portion 302 is manipulatable into a condition in which the first region 305 and the third region 309 extend in a first plane and the second region 307 extends in a second plane that is substantially perpendicular to the first plane. In an example, the base portion 302 is manipulatable from a generally flat condition into a condition in which an internal angle between the first plane in which the first region 305 extends and the second plane in which the second region 307 extends is an obtuse angle.
    [0046] According to the specific example illustrated in Figures 3 to 6 , and referring now in particular to Figure 4 , the base portion 302 has a generally cruciform shape comprising a longer arm 402 having a first end 403 and a second end 404, shown extending in the length direction L, and a shorter arm 405 having a first end 406 and a second end 407, shown extending in the width direction W. The first region 305 and the second region 306 of the base portion 302 are shown positioned along the longer arm 402, in this specific example at opposed ends 403, 404 of the longer arm 402, and the third region 305 of the base portion 302 is shown positioned along the shorter arm 405. According to this specific example, the longer arm 402 extends along a straight line and has a longitudinal axis 408. According to this specific example also, the shorter arm 403 extends along an arc 409 of a circle having a centre (not shown) along the longitudinal axis 408 of the longer arm 402, the arc 409 having a concave side facing towards the second region 307 and a convex side facing towards the first region 305. The shorter arm 405 intersects the longer arm 405 and has concave edging 410 and convex edging 411. The section of the longer arm 402 of the base portion 302 that spans from the concave edging 410 of the shorter arm 405 to the first end 403 of the longer arm 402 is hereinafter referred to as a 'tail' and the section of the longer arm 402 of the base portion 302 that spans from the convex edging 411 of the shorter arm 405 to the second end 404 of the longer arm 402 is hereinafter referred to as a 'tab'.
    [0047] In the present example, the base portion 302 is symmetrical with respect to longitudinal axis 408.
    [0048] It is to be appreciated that the base portion 302 may have any suitable shape.
    [0049] In this example, the securing arrangement 308 comprises adhesive. The adhesive may be provided over a single area, or multiple separate areas, of a surface of the third region 309 of the base portion 302. Preferably, a removable cover layer (not shown) is provided over the adhesive.
    [0050] It is to be appreciated that the securing arrangement 308 may additionally or alternatively comprise a mechanical fixing.
    [0051] In this example, the electrical connector device 306 comprises a socket for engagement with a plug (not shown in Figures 3 to 6 ) of control gear of a luminaire. Alternatively, the electrical connector device 306 may comprise a plug for engagement with a socket of control gear of a luminaire. It is to be appreciated that the electrical connector device 306 may comprise any suitable alternative connection member.
    [0052] In this example, the electronic component 304 is an indicating component. In this example also, the installation element 301 is provided for connecting a visual indicating component, to an emergency power supply associated with a luminaire. Preferably, and in this example, the visual indicating component comprises a light-emitting diode. The light-emitting diode is preferably configured to be illuminated green, optionally configured to be selectively illuminated green or red.
    [0053] In another example, the electronic component 304 is a sensing component. In an example, the installation element 301 is provided for connecting a light detecting component to a daylight harvesting driver associated with a luminaire. Preferably, the light detecting component comprises a surface-mounted photodiode.
    [0054] In a further example, the electronic component 304 is a switching component.
    [0055] It is to be appreciated that the electronic component 304 may be any alternative electronic component. It is further to be understood that the installation element 301 may carry more than one electronic component 304 wired to the printed circuit 303 and electrically connected to the electrical connector device 306, and that a plurality of electronic components 304 of the installation element 301 may comprise electronic components of the same type or of different types.
    [0056] According to the shown arrangement of the present example, the electronic component 304 is an LED indicator configured to project light in a forward direction from the second side 401 of the base portion 302, the electrical connector device 306 is a socket disposed on the first side 310 of the base portion 302 and the securing arrangement 308 is a layer of adhesive on the second side 401 of the base portion 302. A suitable sealant, such as a silicone sealant, is preferably used to waterproof at least the LED indicator 304, but optionally part or all of the second face 401 of the base portion 302.
    [0057] Use of the installation element 301 will now be described with reference to Figures 7 to 12 .
    [0058] The installation element is usable in a method of electrically connecting an electronic component to control gear of a luminaire, the method comprising the steps of identifying a luminaire having control gear and a body member, receiving the installation element, and connecting the electrical connector device of the installation element to the control gear of the luminaire and securing the securing arrangement of the installation element to the body member of the luminaire such that the first region and the second region of the installation element extend in different planes and the electrical component is positionable at an exposed location when the luminaire is installed.
    [0059] As mentioned previously, the installation element 301 of the present example is usable to connect an LED indicator 304 to control gear of a luminaire, such as LED downlight 701 of Figures 7 to 12 . The installation element 301 is shown mounted to LED downlight 701, in an electrically connected condition, in Figures 7 & 8 , and the LED downlight 701 and installation element 301 assembly is illustrated installed within a ceiling in Figures 9 to 12 .
    [0060] As can be seen most clearly in Figures 7 & 8 , the LED downlight 701 comprises a body member 702 including a canister portion 703 having an external surface 704 and a mounting flange portion 705 having a reverse face 706 and an outer rim 707. The installation element 301 is mounted to the LED downlight 701. According to the shown arrangement, the shorter arm 405 of the base portion 302 is secured to the reverse face 706 of the mounting flange 705, using the adhesive of the securing arrangement 308 of the third region 309, the first region 305 of the base portion 302, which supports the LED indicator 304, projects radially outwardly from the mounting flange portion 705 and extends in the same plane as the shorter arm 405 of the base portion 302, and the second region 307 of the base portion 302, which supports the socket 306, extends along the external surface 704 of the canister portion 703 and substantially perpendicularly to the first region 305 of the base portion 302.
    [0061] The canister portion 703 of the LED downlight 701 has a generally cylindrical form, and the mounting flange portion 705 has a generally annular form.
    [0062] It can be seen from Figure 7 in particular that the curvature of the shorter arm 405 of the base portion 302 is designed to complement the curvature at the junction between the canister portion 703 and the mounting flange portion 705 and the curvature of the outer rim 707 of the mounting flange portion 705. Further, a substantially right-angled bend in the base portion 302, along the concave edging 410 of the shorter arm 405 is also visible in Figure 7 .
    [0063] The installation element 301 is attached to the LED downlight 701 with the shorter arm 402 fitted onto the mounting flange portion 704, the tail extending upwards along the canister portion 703 and the tab extending beyond the mounting flange portion 705.
    [0064] As shown in Figures 9 to 13 , with the installation element 301 mounted to the LED downlight 701 as shown in Figures 7 & 8 , when the LED downlight 701 is fitted into a ceiling panel 901, the LED indicator 304 is disposed on the visible, underside 902 of the ceiling panel 901 and the socket 306 is disposed on the concealed, topside 902 of the ceiling panel 901. The LED indicator 304 is sited in an exposed position suitable for normal use. The socket 306 is engageable with a plug of an emergency module (not shown) associated with the LED downlight 701.
    [0065] As most clearly shown in Figure 12 , the first region 305 of the base portion 302, which supports the LED indicator 304, and likewise the third region 309 of the base portion 302, which is provided with the adhesive of the securing arrangement 308, are disposed between the reverse surface 706 of the mounting flange portion 705 of the LED downlight 701 and the underside 902 of the ceiling panel 901.
    [0066] Before, during and after installation of the LED downlight 701 in the ceiling panel, the position of the LED indicator 304 relative to the LED downlight 701 is maintained by being on a tab that is cantilevered from the LED downlight 701.
    [0067] As the LED downlight 701 is installed within the ceiling panel 901, the LED indicator 304 is simultaneously installed at a suitable position without any need for a dedicated mounting aperture to be formed for the LED indicator 304 and without requiring the use of any tools to site the LED indicator 304.
    [0068] An installation element 1301, according to a second embodiment, is shown in Figures 13 to 16 . The installation element 1301 of this second illustrated embodiment is suitable for connecting an electronic component to control gear of a luminaire, and is, for example, usable to connect a light sensor 1302 to control gear of a luminaire, such as LED panel 1303 of Figures 13 to 16 . The installation element 1301 is shown mounted to LED panel 1303, in an electrically connected condition, in Figures 13 & 14 , and the LED panel 1303 and installation element 1301 assembly is illustrated installed within a ceiling in Figures 15 & 16 . The installation element 1301, and use of the installation element 1301, will be described with reference to Figure 13 to 16 .
    [0069] The installation element 1301 of Figures 13 to 16 is similar to the installation element 301 of Figures 3 to 12 ; however, the shape of the installation element 1301 differs from the shape of the installation element 301, as the LED panel 1303 has a body member 1304 that differs in shape to the body member 702 of LED downlight 701.
    [0070] In this present example, the installation element 1301 has a base portion 1401 having a first face 1402 and a second face 1403. A first region 1404 of the base portion 1401 supports the light sensor 1302. In this example, the light sensor 1302 is a surface-mounted photodiode. A second region 1405 of the base portion 1401 supports an electrical connector device 1406. In this example, the electrical connector device 1406 is a socket. The electrical connector device 1406 is usable to connect the light sensor 1302 to a daylight harvesting driver (not shown) associated with the LED panel 1303. A third region 1407 of the base portion 1401 supports a securing arrangement for attaching the base portion 1401 to the LED panel 1303. In this example, the securing arrangement is adhesive, which is provided on the first face 1402 of the base portion 1401.
    [0071] The body member 1304 of LED panel 1303 is substantially rectangular with corners 1305, an obverse face 1306 and a reverse face 1307.
    [0072] In common with the installation element 301, the second region 1405 of the base portion 1401 of the installation element 1301 is spaced from the first region 1404 of the base portion 1401, the base portion 1401 is flexible to allow the base portion 1401 to be manipulated into a condition in which the first region 1404 and the second region 1405 extend in different planes, and the third region 1407 of the base portion 1401 is separate from the second region 1405 of the base portion 1401.
