[0003] LIGHT MODULE WITH MULTIPLE LIGHT SOURCE BOARDS

[0004] TECHNICAL FIELD

[0005] The present disclosure relates generally to lighting and related solutions, and in particular to a light source module with multiple light source boards and lighting devices having such light modules.

[0006] BACKGROUND

[0007] Some light fixtures have multiple light emitting diode (LED) boards that provide the light provided by the lighting fixtures. Power is provided to the multiple LED boards of such a light fixture using multiple electrical wires. For example, multiple electrical wires may be used to connect an LED driver to the multiple LED boards. To illustrate, different electrical wires of a wire harness may be routed to different LED boards of a light fixture. Routing a relatively large number of electrical wires to the different LED boards of a light fixture can be time consuming and error prone. In some cases, some of the wires that are routed to the LED boards can be unintentionally pinched or cut, resulting in a defective lighting device. Thus, a solution that simplifies providing power to multiple light source boards of a light fixture may be desirable.

[0008] SUMMARY

[0026] DETAILED DESCRIPTION OF THE EXAMPLE EMBODIMENTS

[0027] In the following paragraphs, particular embodiments will be described in further detail by way of example with reference to the figures. In the description, well known components, methods, and / or processing techniques are omitted or briefly described. Furthermore, reference to various feature(s) of the embodiments is not to suggest that all embodiments must include the referenced feature(s).

[0028] Turning now to the drawings, example embodiments are described. FIG. 1 illustrates a light module 100 having multiple light source boards according to an example embodiment. In some example embodiments, the light module 100 may include a power routing board 102 and multiple light source boards 104, 106, 108, 110, 112, 114, 116, 118. The light module 100 may be included in a light fixture where the light module 100 provides the light provided by the light fixture. To illustrate, the light provided by the light module 100 may be a combination of lights provided by the light source boards 104-118.

[0029] In some example embodiments, the light source boards 104-118 may be attached to the power routing board 102. To illustrate, the power routing board 102 may include a power routing printed circuit board 120 that includes copper traces. The terms “copper trace” and “copper traces” are intended to refer to printed circuit board trace(s) made from copper and / or other metal(s). The light source boards 104-118 may be attached to the power routing printed circuit board 120 such that the light source boards 104-118 are individually conductively (i.e., electrically) connected to the copper traces of the power routing printed circuit board 120. For example, the copper traces of the power routing printed circuit board 120 may be used to provide power to the light source boards 104-118. The light source boards 104-118 may be attached to the power routing printed circuit board 120, for example, using mating electrical connectors that serve to provide a structural attachment as well as electrical coupling. Alternatively, the light source boards 104-118 may be attached to the power routing printed circuit board 120, for example, using mating mechanical 2024PF80277

[0030] 4 connectors, where electrical connections are made separate from the mechanical connectors, such as using separate electrical connectors and / or solder.

[0031] In some example embodiments, each light source board of the light source boards 104-118 may include a light source printed circuit board and light sources that are attached thereto. The light source printed circuit board of each light source board of the light source boards 104-118 may be attached to the power routing printed circuit board 120 such that the copper traces of the power routing printed circuit board 120 are conductively connected to the light sources of each light source board of the light source boards 104-118. The copper traces of the power routing printed circuit board 120 may be conductively connected to each light source board of the light source boards 104-118 such that power can be provided to the light sources of each light source printed circuit board over the copper traces. The light sources of the light source boards 104-118 may also be conductively connected to each other by the copper traces.

[0032] In some example embodiments, the light sources of each light source board of the light source boards 104-118 may include light emitting diodes (LEDs). For example, the light source boards 104-118 may each include a light emitting diode (LED) board that includes an LED printed circuit board and LEDs that are attached to the LED printed circuit board. Each LED printed circuit board may be conductively connected to the copper traces of the power routing printed circuit board of the power routing board 102 such that power can be provided to the LEDs over the copper traces.

[0033] In some example embodiments, the light source boards 104-118 are positioned perpendicular to the power routing board 102. For example, the light source printed circuit board of each light source board of the light source boards 104-118 may be positioned perpendicular to the power routing printed circuit board 120 of the power routing board 102. The power routing board 102 may have an enclosed shape that encloses an area, and the light source boards 104-118 may be perpendicularly attached to the power routing board 102 such that the light sources of the light source boards 104-118 are oriented to emit lights toward the enclosed area. For example, LED printed circuit boards may be perpendicularly attached to the power routing printed circuit board 120 of the power routing board 102 such that the LEDs attached to the LED printed circuit boards are oriented to emit lights toward the area enclosed by the power routing board 102. In some alternative embodiments, the light source boards 104-118 may be attached to the power routing board 102 such that the light sources of the light source boards 104-118 are oriented to emit lights outwardly relative to the enclosed area. 2024PF80277

[0034] 5

[0035] In some example embodiments, power may be provided to the light module 100 over an electrical cable 122. The electrical cable 122 may be connected to a power supply, such as an LED driver, that can provide power to the light sources of the light source boards 104-118 over the electrical cable 122. To illustrate, the electrical cable 122 may include a pair of electrical wires that may be conductively connected to the copper traces of the power routing printed circuit board 120 of the power routing board 102. For example, one wire of the pair of wires of the electrical cable 122 may be conductively connected to one copper trace of the power routing printed circuit board 120, and another wire of the pair of wires of the electrical cable 122 may be conductively connected to another copper trace of the power routing printed circuit board 120. The electrical cable 122 may be conductively connected to the copper traces of the power routing board 102 using electrical connectors and / or by solder. Because the copper traces of the power routing board 102 are conductively connected to the light source boards 104-118, a power supply can provide power to the light sources of the light source boards 104-118 using the pair wires of the electrical cable 122.

[0036] By using the power routing board 102 to provide power from a power supply to the light source boards 104-118, the number of electrical wires that are needed to provide power to light modules can be significantly reduced (e.g., two electrical wires). By reducing the number of electrical wires needed to provide power to light modules, the use of the power routing board 102 along with the light source boards 104-118 can significantly reduce the problems associated wire pinching and cutting that often occur with light modules that have significantly more than two wires for providing power to the light sources of the light modules. In addition, by reducing the number of electrical wires needed to provide power to the light module 100, the time needed to assemble a lighting device that includes the light module 100 can be significantly reduced.

[0037] In some alternative embodiments, the light module 100 may include more or fewer light source modules than shown without departing from the scope of this disclosure. For example, the light module 100 may include two, three, four, five, six, nine, ten, or more source modules. In some alternative embodiments, the power routing board 102 may have a different shape than shown without departing from the scope of this disclosure. For example, the power routing board 102 may have a triangular shape or rectangular shape. In general, the power routing board may include multiple segments oriented at angles relative to each other. In some alternative embodiments, the electrical cable 122 may include more than two electrical wires without departing from the scope of this disclosure. 2024PF80277

[0039] FIG. 2 illustrates the power routing board 102 of the light module 100 of FIG.

[0040] 1 according to an example embodiment. In some example embodiments, the power routing board 102 includes the power routing printed circuit board 120 and an electrical connector 202. For example, the power routing printed circuit board 120 may be a rigid printed circuit board that includes copper traces 220 that are routed on the surface or at a lower layer of the power routing printed circuit board 120. For example, the copper traces 220 include two or more copper traces that can be used to provide power to electrical components that are directly or indirectly connected to the copper traces 220. Each copper trace of the copper traces 220 may form an enclosed shape that generally follows the shape of the power routing printed circuit board 120. For example, the power routing board 102 may form an enclosed shape that encloses an area 226. To illustrate, the power routing printed circuit board 120 may have an enclosed shape that encloses the area 226, and the copper traces 220 may generally have the same shape as the power routing printed circuit board 120.

[0041] In some example embodiments, the electrical connector 202 may be connected to the electrical cable 122 and to the copper traces 220 of the power routing printed circuit board 120, thereby establishing electrical connections between the electrical cable 122 and the copper traces 220. The electrical connector 202 may be soldered to the power routing printed circuit board 120. The electrical cable 122 may be connected, indirectly by another electrical cable and / or connector or directly, to a power supply such as an LED driver that can provide power to the light module 100.

[0042] In some example embodiments, the power routing board 102 includes multiple electrical connectors 204, 206, 208, 210, 212, 214, 216, 218 that are attached to the power routing printed circuit board 120. The electrical connectors 204-218 may be at different locations from each other on the power routing printed circuit board 120. In general, the electrical connectors 204-218 are located to connect to a mating electrical connector of a respective light source board of the light source boards 104-118 of the light module 100 shown in FIG. 1. For example, the electrical connectors 204-218 may each be a female electrical connector or a male electrical connector. The electrical connectors 204-218 may each be physically connected to the copper traces 220 of the power routing printed circuit board 120, thereby establishing electrical connections between the electrical connectors 204- 218 and the copper traces 220. The electrical connectors 204-218 may be soldered to the power routing printed circuit board 120.

[0043] Referring to FIGS. 1 and 2, in some example embodiments, the electrical connector 204 is mechanically and electrically connected to an electrical connector of the 2024PF80277

[0044] 7 light source board 104. The electrical connector 206 may be mechanically and electrically connected to an electrical connector of the light source board 106. The electrical connector 208 may be mechanically and electrically connected to an electrical connector of the light source board 108. The electrical connector 210 may be mechanically and electrically connected to an electrical connector of the light source board 110. The electrical connector 212 may be mechanically and electrically connected to an electrical connector of the light source board 112. The electrical connector 214 may be mechanically and electrically connected to an electrical connector of the light source board 114. The electrical connector 216 may be mechanically and electrically connected to an electrical connector of the light source board 116. The electrical connector 218 may be mechanically and electrically connected to an electrical connector of the light source board 118.

[0045] In some example embodiments, the electrical connectors 204-218 of the power routing printed circuit board 120 may each be a female connector that positioned to receive the pins of a respective male connector of the light source boards 104-118. Alternatively, the electrical connectors 204-218 may each be a male connector having pins that are inserted into a respective female connector of the light source boards 104-118. The electrical connectors 204-218 along with the respective electrical connectors of the light source boards 104-118 may provide both structural attachment and electrical coupling between the power routing printed circuit board 120 and the light source boards 104-118. For example, the attachment of the electrical connectors 204-218 of the power routing printed circuit board 120 to the electrical connectors of the light source boards 104-118 may provide adequate structural stability for the light source boards 104-118 to be positioned perpendicular to the power routing printed circuit board 120 such that the light sources of the light source boards 104- 118 emit lights, for example, toward the area 226.

[0046] In some example embodiments, the power routing printed circuit board 120 may include joint sections, such as joint sections 222, 224, that are each between sections of the power routing printed circuit board 120 designated for the attachment of the light source boards 104-118. For example, the joint sections including the joint sections 222, 224 may provide as an area for placing of a fastener or a clip to securely attach the power routing printed circuit board 120 to a housing of a light fixture. In some alternative embodiments, the joint sections may have a different shape than shown without departing from the scope of this disclosure. In some alternative embodiments, adjacent sections of the power routing printed circuit board 120 designated for the attachment of the light source boards 104-118 may be 2024PF80277

[0047] 8 directly connected. For example, the power routing printed circuit board 120 may have an octagonal shape or another shape that does not include joint sections.

[0048] FIG. 3 illustrates a closeup view of a portion of the light module 100 of FIG. 1 according to an example embodiment. In some example embodiments, the light source boards 104, 106, 108 may be perpendicularly attached to the power routing printed circuit board 120 of the power routing board 102 of the light module 100 shown in FIG. 1. The light source board 104 may include a light source printed circuit board and light sources 304 (e.g., LEDs) attached to the light source printed circuit board. The light source board 106 may include a light source printed circuit board and light sources 306 (e.g., LEDs) attached to the light source printed circuit board. The light source board 108 may include a light source printed circuit board and light sources 308 (e.g., LEDs) attached to the light source printed circuit board.

[0049] In some example embodiments, the light source board 104 includes the electrical connector 202 that is electrically connected to the copper traces 220 of the power routing printed circuit board 120. The electrical connector 202 may also be electrically connected to the electrical cable 122 that can be used to provide power provided from a power supply (e.g., an LED driver) to the light module 100.

[0050] In some example embodiments, the light source board 106 includes an electrical connector 310 that is mating attached to the electrical connector 206. The electrical connector 310 is conductively connected to the light sources 306 of the light source board 106. The electrical connector 310 may be, for example, soldered to the light source printed circuit board of the light source board 106. Because the electrical connector 310 is electrically connected to the light sources 306 of the light source board 106 and to the electrical connector 206 that is electrically connected to the electrical cable 122 via the electrical connector 202 that is electrically connected to the copper traces 220, power from a power supply can be provided to the light source board 106. Power from the power supply can be provided to the light sources of the other light source boards 104, 108-118 in the same manner.

[0051] FIG. 4 illustrates the light source board 106 unattached to the power routing board 102 of the light module 100 of FIG. 1 according to an example embodiment. Referring to FIGS. 3 and 4, in some example embodiments, the light source board 106 includes a light source printed circuit board 402, the light sources 306 (e.g., LEDs), and the electrical connector 310. The light sources 306 are attached to the light source printed circuit board 402 and are electrically connected to the electrical connector 310, for example, by copper traces 2024PF80277

[0052] 9 of the light source printed circuit board 402. The electrical connector 310 of the light source board 106 may be attached to the electrical connector 206 of the power routing board 102 as shown in FIG. 3 such that the light source printed circuit board 402 is positioned perpendicular to the power routing printed circuit board 120. Because the electrical connector 206 is electrically connected to the copper traces 220 of the power routing printed circuit board 120, power may be provided to the light sources 306 over the copper traces 220 that are electrically connected to the electrical cable 122.

[0053] FIG. 5 illustrates a light source board 500 corresponding to the light source boards 104-118 of the light module 100 of FIG. 1 according to an example embodiment. In some example embodiments, the light source board 500 may include a light source printed circuit board 502, light sources 504 (e.g., LEDs), and an electrical connector 506. For example, the light source printed circuit board 502 may be a rigid printed circuit board. The light sources 504 and the electrical connector 506 are attached to the light source printed circuit board 502. For example, the light sources 504 and the electrical connector 506 may be soldered and / or connected by a fastener to the light source printed circuit board 502. the electrical connector 506 may be located to be attached to a corresponding mating electrical connector of the power routing board 102 shown, for example, in FIG. 1. The electrical connector 506 may be a male connector as shown in FIG. 5 or a female connector. The light source printed circuit board 502 may be attached to the power routing board 102 by the electrical connector 506 and a mating electrical connector of the power routing board 102 such that the light source printed circuit board 502 is perpendicular to the power routing board 102.

[0054] Referring to FIGS. 1-5, in some example embodiments, the light source board 500 corresponds to each one of the light source boards 104-118 of the light module 100. That is, the light source boards 104-118 may each be an instance of the light source board 500. For example, the light source board 500 may correspond to the light source board 106, where the light source printed circuit board 502 corresponds to the light source printed circuit board 402 and where the electrical connector 506 corresponds to the electrical connector 310. In general, the light source board 500 may correspond to the light source boards 106-118 in the same manner.

[0055] In some alternative embodiments, the light source board 500 may include more or fewer light sources than shown without departing from the scope of this disclosure. In some alternative embodiments, the light source board 500 may have a different shape than shown without departing from the scope of this disclosure. In some alternative embodiments, 2024PF80277

In some example embodiments, the light module 600 includes a power routing board 602 and the light source boards 604, 606, 608 that are attached to the power routing board 602. The power routing board 602 may include a power routing printed circuit board 610 and an electrical connector 614 attached to the power routing printed circuit board 610. The electrical connector 614 may be conductively connected to copper traces 616 of the power routing printed circuit board 610 that may be conductively connected to an electrical cable 612. The electrical cable 612 may be used to provide power to the light module 600 from a power supply (e.g., an LED driver).

[0058] In some example embodiments, the light source boards 604, 606, 608 may be mechanically and electrically connected to the power routing board 602. For example, the light source boards 604, 606, 608 may be positioned perpendicular to the power routing printed circuit board 610. In particular, the printed circuit board of each one of the light source boards 604, 606, 608 may be mechanically and electrically connected to the power routing printed circuit board 610 by mating connectors in the manner described with respect to the light module 100 of FIG. 1.

The electrical cable 714 may be used to provide power to the light module 700 from a power supply (e.g., an LED driver).

[0062] In some example embodiments, the light source boards 704, 706, 708, 710 may be mechanically and electrically connected to the power routing board 702. For example, the light source boards 704, 706, 708, 710 may be positioned perpendicular to the power routing printed circuit board 712.

For example, the light module 100 and the edge-lit panel 808 may be positioned on the housing frame 804 such that lights that are provided by the light module 100 enter the edge-lit panel 808 through a narrow edge 812 of the edge-lit panel 808 and exit through a broad surface 814 (i.e., the surface of the edge-lit panel 808 facing the housing frame 804) of edge-lit panel 808.

[0066] To illustrate, the light source boards 104-118 are positioned perpendicular to the power routing board 102 that is positioned on the housing frame 804. The light source boards 104-118 may be positioned to emit respective lights inwards relative to the inside of the housing 802. For example, FIG. 9 shows the light source boards 104, 106, 108 positioned perpendicular to the power routing board 102 that is positioned on the housing frame 804. The light module 100 may be held in position, for example, by clips such as a clip 902.

[0067] In some example embodiments, power from a power supply, such as an LED driver, may be provided to the light module 100 via the electrical cable 122 that is conductively connected to light module 100 as described above. For example, a power supply may be positioned in a cavity of the housing frame 804, at another location in the housing 802, or separate from the lighting device 800. To illustrate, the electrical cable 122 may be routed to the power supply via a conduit in a frame branch 816 of the housing frame 804.

[0068] By using the power routing board 102 and by connecting the light source boards 104-118 as described above, the number of electrical wires that are needed to provide power to the light module 100 can be significantly reduced (e.g., two electrical wires). By reducing the number of electrical wires needed to provide power to the light module 100, the time needed to assemble a lighting device that includes the light module 100 can be significantly reduced.

[0069] In some alternative embodiments, the lighting device 800 may have a different shape than shown without departing from the scope of this disclosure. For example, the lighting device 800 may include the lighting module 600 or the lighting module 700 instead of the lighting module 100. In some alternative embodiments, the lighting device 800 may be a different type of light fixture than shown without departing from the scope of this disclosure. For example, the lighting device 800 may not be an edge-lit lighting device. In general, the lighting device 800 may be an indoor or outdoor light fixture. In some alternative embodiments, the lighting device 800 may include more or fewer components than shown without departing from the scope of this disclosure. 2024PF80277
