[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0037] It should be noted that when a component is referred to as being "connected" to another component, it can be directly connected to the other component or there can be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used in the specification of this utility model herein are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0039] See Figures 1 to 4 , this utility model provides a light source module, including a heat sink 100, a first substrate 200, and a second substrate 300. Among them, the heat sink 100 has a side surface 110 and an end surface 120 that are perpendicular to each other. A first LED lamp bead 260 is disposed on the first substrate 200 and fixed on the side surface 110. The first substrate 200 serves as a light-emitting component and dissipates the heat generated during operation through the heat sink 100. The first substrate 200 includes a first base layer 210, a first circuit layer 230, and a first solder mask layer 240. The first solder mask layer 240 is opened to form a first pad 250. The second substrate 300 includes a second base layer, a second circuit layer, and a second solder mask layer. The second solder mask layer is opened to form a second pad. The first substrate 200 and the second substrate 300 are vertically inserted and electrically connected by soldering the first pad 250 and the second pad adjacent to the insertion position. This structure facilitates assembly and circuit layout for the light-emitting component.

[0040] Furthermore, the first substrate 200 has an insertion portion 270 that penetrates the first substrate 200. The second substrate 300 has a slot 320 that cooperates with the insertion portion 270. The first pad 250 and the second pad are disposed on both sides of the insertion position. During assembly, the first substrate 200 is vertically inserted into the slot 320 of the second substrate 300 through the insertion portion 270 and then effectively fixed by soldering, making the operation simpler and more convenient.

[0041] Among them, the first base layer 210 and the first circuit layer 230 are made of metal materials. The first substrate 200 further includes a first insulating layer 220, and the first insulating layer 220 is disposed between the first base layer 210 and the first circuit layer 230. Specifically, the first base layer 210 and the first circuit layer 230 are metal layers. For example, the first base layer 210 is an aluminum base layer, and the first circuit layer 230 is a copper film layer. An insulating layer is disposed between the two metal layers to avoid mutual conduction and play a protective role.

[0042] See Figure 1In the illustrated embodiment, there are multiple first substrates 200, and each first substrate 200 is vertically welded to the second substrate 300. The second substrate 300 serves as a connecting board, and through the second substrate 300, multiple first substrates 200 can be driven to work simultaneously. The multiple first substrates 200 surround the radiator 100 circumferentially. On the one hand, it is beneficial to the heat dissipation of each first substrate 200. On the other hand, a multi-angle light-emitting surface is formed by surrounding the radiator 100, enabling the light emission of the light source module to meet the application requirements of different lighting scenarios.

[0043] See Figure 3 , a clamping groove 131 is provided on the side surface 110 of the radiator 100 to facilitate the installation and fixation of the first substrate 200. The second substrate 300 is fixed to the radiator 100 through the first fastener 340. Correspondingly, a first connection hole 142 is provided on the end surface 120 of the radiator 100, and the first connection hole 142 cooperates with the first fastener 340. The radiator 100 is a hollow structure, and the second substrate 300 has a second through hole 330 communicating with the inner cavity of the radiator 100 for heat dissipation and wire arrangement.

[0044] Specifically, the radiator 100 includes a metal profile 130 and a metal backing plate 140, which enclose a hollow structure. Among them, the cross-sectional shape of the metal profile 130 is uniform and has a side surface 110 on which the first substrate 200 can be installed. The first substrate 200 is fixed to the outer surface of the metal profile 130. The metal backing plate 140 is arranged at the end of the metal profile 130 and has an end surface 120 for installing the second substrate 300. The second substrate 300 is fixed to the metal backing plate 140.

[0045] See Figure 1 、 2 , the second substrate 300 is provided with a second connection hole 350 that cooperates with the first fastener 340, and the metal profile 130 is provided with a first fixing hole 132 that cooperates with the first fastener 340. During assembly, the first substrate 200 and the metal backing plate 140 can be fixed to the metal profile 130 using the first fastener 340. The metal backing plate 140 is also provided with a first through hole 141 communicating with the second through hole 330, which is beneficial for internal heat dissipation and wire arrangement.

[0046] In one embodiment, the second substrate 300 is provided with second LED lamp beads 310 to increase the light-emitting surface of the light source module, making the light emission of the light source module more flexible and the application scenarios more extensive. Among them, the second substrate 300 can be a multi-layer substrate, such as a multi-layer fiberglass board, and can include multiple second circuit layers, which is convenient for circuit arrangement to meet the usage requirements of the first substrate 200 and the second substrate 300 itself, such as realizing the connection of multiple first substrates 200 and driving the second LED lamp beads 310 on the second substrate 300 to work.

[0047] See Figures 5 to 10, an embodiment of the present utility model provides a lighting fixture, which includes the aforementioned light source module, a lamp head 400, and a lamp shade 500. Among them, the lamp shade 500 is a cylindrical structure with one end open and the other end closed. The light source module is arranged inside the lamp shade 500. The open end of the lamp shade 500 is connected to the lamp head 400, and the second substrate 300 is located at the closed end of the lamp shade 500.

[0048] Specifically, in the light source module, one end of the radiator 100 is fixedly connected to the lamp head 400, and the other end is located on the closed wall of the lamp shade 500. The lamp shade 500 is a split structure, including a main body part 510 and a cover 520. Both ends of the main body part 510 are open. One end is connected to the lamp head 400, and the other end is cooperatively connected with the cover 520 to achieve closure. Further, the cover 520 can be connected to the radiator 100 through a second fastener 521, for example, connected to the metal profile 130. See Figure 10 .

[0049] In one embodiment, a driving power supply 600 is arranged inside the lamp head 400. The second substrate 300 is electrically connected to the driving power supply 600 through a wire. The wire can extend into the interior of the radiator and is sequentially connected to the second substrate 300 through a first through hole 141 and a second through hole 330; a conductive part 420 electrically connected to the driving power supply 600 for connecting to an external power supply is arranged on the lamp head 400. For example, in a pluggable lamp, the lamp head 400 includes a diameter-expanded part 410, and the driving power supply 600 is arranged inside the diameter-expanded part 410.

[0050] By arranging the second substrate 300 in the light source module in the present utility model, it is beneficial to facilitate the installation of the first substrate 200 and the layout of the circuit.
