Luminaire with LED cartridges

Description

FIELD OF THE INVENTION

[0001] The present invention relates to luminaires, and more particularly to luminaires formed with LED cartridges.

BACKGROUND

[0002] In recent years LED luminaires have become popular because they are more energy efficient and last longer than luminaires incorporating traditional light sources such as incandescent or fluorescent lights. One drawback of LED luminaires is that, unless costly electronic controls are provided in the luminaire, it can be difficult to increase or decrease the light output of the luminaire if the desired output changes once the luminaire is installed, unlike traditional luminaires in which the existing light bulb can be replaced with one having a higher or lower wattage. Further, when an LED in an LED luminaire does fail, it is often more difficult to replace than the light bulb in a traditional luminaire. Luminaires of the prior art are disclosed in WO 2011/023037 A1, US 2012/162987 A1, US 2013/088864 A1, US 2009/168416 A1, EP 2 327 930 A1 and CN 101 532 624 A.

DETAILED DESCRIPTION

[0037] The subject matter of features of the present invention is described here with specificity to meet statutory requirements, but this description is not necessarily intended to limit the scope of the claims. The claimed subject matter may be embodied in other ways, may include different elements or steps, and may be used in conjunction with other existing or future technologies. This description should not be interpreted as implying any particular order or arrangement among or between various steps or elements except when the order of individual steps or arrangement of elements is explicitly described.

[0038] Certain features of the invention include a luminaire having an electronic housing and at least one LED cartridge mounted onto the electronic housing. The electronic housing includes at least one compartment for housing the driver and/or other electronics for powering and controlling the luminaire. In one illustrated, non-limiting embodiment, two compartments are provided in the electronic housing, each adapted to house a driver. However, any number of compartments may be provided, depending upon the needs of the luminaire.

[0039] In the illustrated embodiment, the two compartments are integrally formed with a wire passageway provided between them. However, other configurations of the electronic housing are certainly contemplated. The electronic housing may be formed from any material having suitable rigidity and thermal properties, including by not limited to metallic materials, such as steel, aluminum, etc.

[0040] A plate is positioned on the underside of the electronic housing to enclose the compartments and contain the electronics housed therein. The plate may be hinged to the housing on one side (see Figure 8) so that the plate remains attached to the housing during servicing of the electronics. However, such hinged attachment is certainly no required. A gasket may optionally be provided at the interface between the electronic housing and the plate to ensure that the compartments are airtight to prevent dust and debris from entering a compartment and detrimentally impacting the electronics therein.

[0041] Any number of LED cartridges may be mounted on the housing, as discussed in more detail below. Each LED cartridge includes a metal (such as aluminum) casting, a printed circuit board ("PCB") populated with light emitting diodes ("LEDs"), and an optic having lenses for positioning over the PCB so that the lenses direct the light emitted by the LEDs. See Figures 3 and 9-11. In some embodiments, the casting includes a recess in its underside to receive the PCB and optic. The PCB and optic may be retained on the casting in any of a variety of ways, including with screws that extend through the optic and PCB and engage the casting. Provision of a recess forms a casting skirt around the LED cartridge to prevent light pollution at 90° from nadir and above. While the casting is shown as chevron-shaped, it could assume other geometric shapes, including, but not limited to, rectangular, square, trapezoidal, polygonal, rhombus, octagonal, pentagonal, hexagonal, etc.

[0042] The PCB may any type of board, including, among others, a metal core board, FR4 board, CHM1 board, etc. Any type and number of LEDs may be arranged on the PCB in any configuration. The LEDs can be single-die or multi-die light emitting diodes, DC or AC, or can be organic light emitting diodes. LEDs need not be only white LEDs. Rather color or multicolor LEDs may be provided. Nor must all of the LEDs on a PCB be the same color.

[0043] The optic may be a monolithic piece of acrylic, polycarbonate or other suitable material with the lenses formed integrally therein. A gasket (not shown) may be positioned between the optic and the PCB to protect the LEDs from dust and other contaminants. In the illustrated embodiment, the optic is an optical assembly that includes a frame having apertures that receive the lenses. While the frame and lenses could be formed separately and then assembled together, in some embodiments the frame and lenses are integrally formed in a molding process. In one such embodiment, the lenses are formed and positioned in a mold. The frame is then molded around the lenses so that the frame material (e.g., acrylic, polycarbonate, etc.) fuses with the lens material so as to form an integral optic. To the extent one is used, a gasket can be co-molded with the optic so that the resulting optical assembly includes a frame, lenses, and gasket all integrally-formed.

[0044] An optic may be provided with lenses of any type (e.g., Type I-V), and indeed not all of the lenses within an optic need be the same. Moreover, the type, number, and arrangement of LEDs on the PCBs, as well as the lens types provided on the optics, may be different between the different LED cartridges provided in a luminaire.

[0045] Any number of LED cartridges may be mounted on and electrically connected to the electronic housing. See, e.g., Figures 12 and 22. In one embodiment (see Figure 21), each LED cartridge has plug-in electrical connectors so that the necessary electrical connections are made when the cartridge is snapped into an adjacent cartridge (or directly into the electronic housing, if the first in the LED cartridge series).

[0046] In an alternative embodiment (see Figures 1-20), the LED cartridges are indirectly connected to each other and to the electronic housing using a mounting arm. The mounting arm is mounted to the electronic housing and any number of LED cartridges can then be mounted to the mounting arm. Obviously the length of the mounting arm provided in a luminaire will depend on the number of LED cartridges used in the luminaire. The mounting arm may be formed of any material having suitable rigidity and strength to support the LED cartridges, including, but not limited to, metallic materials such as steel, aluminum, etc. Fabrication of the electronic housing, LED cartridge castings, and mounting arm from a thermally conductive material facilitates removal of heat from the assembly. Moreover, the LED cartridges are not directly connected to each other or to the electronic housing. Rather, passageways for convective cooling are provided between adjacent LED cartridges, as shown in Figure 4. Thermal isolation of the electronic housing from the LED cartridges reduces heat transfer to the electronic housing, thereby increasing the luminaire life by keeping the drivers cooler. Moreover, the mounting arm provides a grounding path for each of the LED cartridges.

[0047] The electrical connections are made using a plug and play assembly whereby wires from the electronic housing are connected with the first LED cartridge in a series and, thereafter, the electrical connections are made between adjacent LED cartridges in that series. For example, Figure 2 illustrates an embodiment of a luminaire provided with eight LED cartridges. The first set of four LED cartridges is powered by a first driver, and the second set of four LED cartridges is powered by a second driver. Electrical connections from the electronic housing to the first LED cartridge in the first set are made. Electrical connections are subsequently made with adjacent LED cartridges to thereby connect in series all of the LED cartridges in the first set. With respect to the second set of LED cartridges, wires from the electronic housing bypass the first set of LED cartridges so that the first LED cartridge in the second set is directly connected with the electronic housing (or more specifically, the second driver housed therein). The remaining LED cartridges in the second set are subsequently connected in series to each other.

[0048] The electrical connections are made on the top of the LED cartridge castings so as to be covered by the mounting arm. A recess may be formed in the top of each casting to accommodate the mounting arm. Ribs may be provided in the underside of the mounting arm so as to form a channel or wireway in which the wires may be safety positioned to prevent damage (such as caused by wire pinching). Moreover, ribs may also extend upwardly from a casting to assist with proper positioning of the mounting arm on the casting and help delineate the wireway.

[0049] The use of self-contained LED cartridges facilitates manufacture of a customized luminaire tailored for a particular application. A luminaire emitting the desired light distribution may be configured by controlling the number of LED cartridges used in the luminaire as well as the lumen package and optic selected for each cartridge. Assembly of the luminaire is facilitated by the easy plug and play electrical connections between LED cartridges, which also enable modification of the luminaire (removal, addition, or replacement of LED cartridges) in the field.

[0050] The luminaire may be pole-mounted (see Figures 1, 4-8, 12, and 17-20) or side-mounted (see Figures 12-16). In one embodiment, the electronic housing couples with a pole adapter which brings the cables up from the pole and into the electronic housing. A cable cover (see Figure 1) may be provided to cover the cable coming from the pole adapter (or wall if wall- or side-mounted). Moreover, a trim piece may be provided on the end of the distal-most LED cartridge to impart a polished appearance to the luminaire.

[0051] In one or more embodiments, the luminaire may be tilted relative to the space to be illuminated by 0 to 20 degrees tilt. In particular, the luminaire may be tilted relative to the space to be illuminated by 0 to 5 degrees tilt.

[0052] Figures 23 to 64 show various views of a luminaire in accordance with an embodiment of the present invention. In particular, these views show a luminaire having different numbers of LED cartridges attached.

[0053] The foregoing is provided for purposes of illustrating, explaining, and describing embodiments of the present invention. Further modifications and adaptations to these embodiments will be apparent to those skilled in the art and may be made without departing from the scope of the invention. Different arrangements of the components depicted in the drawings or described above, as well as components and steps not shown or described are possible. Similarly, some features and subcombinations are useful and may be employed without reference to other features and subcombinations. Embodiments of the invention have been described for illustrative and not restrictive purposes, and alternative embodiments will become apparent to readers of this patent.
