[0041] Reference Figure 1 , Figure 2 and Figure 6 The light source module according to an embodiment of this application includes: a support portion 100, a first sealant 200, a light-transmitting portion 300, a second sealant 400, and a light source portion 500.

[0042] The support part 100 has a groove 110;

[0043] The first sealant 200 is disposed within the groove 110;

[0044] The light-transmitting part 300 is provided with a compression structure 310, which is inserted into the groove 110. A sealing channel 320 is formed between the compression structure 310 and the groove wall of the groove 110. The compression structure 310 is used to compress the first sealant 200 in the groove 110 so that the first sealant 200 fills the sealing channel 320. An opening 321 communicating with the outside is formed on one side of the sealing channel 320.

[0045] The second sealant 400 is disposed within the sealing channel 320 and is connected to the side of the first sealant 200 that is filled within the sealing channel 320 near the opening 321.

[0046] The light source 500 is disposed on the support surface 113 of the support 100 and is located between the support 100 and the light-transmitting part 300.

[0047] It is understood that one assembly process of the light source module in this application is as follows: First, referring to... Figure 3 The light source 500 is fixed to one side of the support 100. Then, refer to... Figure 4 Then, inject the first sealant 200 into the groove 110. Next, refer to... Figure 5 A supporting portion 100 and a light-transmitting portion 300 are connected, forming a receiving cavity 330 between the supporting portion 100 and the light-transmitting portion 300 to accommodate the light source portion 500. A pressing structure 310 of the light-transmitting portion 300 is inserted into a groove 110, forming a generally U-shaped sealing channel 320 between the pressing structure 310 and the groove wall of the groove 110. One side of the sealing channel 320 communicates with the receiving cavity 330, and one side of the sealing channel 320 forms an opening 321 communicating with the outside. Simultaneously, the pressing structure 310 presses the first sealant 200 within the groove 110, filling the sealing channel 320 with the first sealant 200. Then, refer to... Figure 6 The second sealant 400 is injected into the sealing channel 320 through the opening 321, and the second sealant 400 is made to fill the sealing channel 320 as much as possible. After the first sealant 200 and the second sealant 400 have solidified, two waterproof barriers can be formed, which can waterproof the light source part 500 between the support part 100 and the light-transmitting part 300.

[0048] Therefore, by the extrusion structure 310 of the light-transmitting part 300 extruding the first sealant 200 in the groove 110 of the support part 100, the first sealant 200 can be better filled in the sealing channel 320 between the extrusion structure 310 and the groove wall of the groove 110, ensuring the amount of the first sealant 200 in the sealing channel 320. Then, by injecting the second sealant 400 into the sealing channel 320, the amount of sealant in the sealing channel 320 can be further increased, thereby improving the sealing between the light-transmitting part 300 and the support part 100, so as to ensure the waterproof effect of the light source module of this application.

[0049] Specifically, in some embodiments, reference is made to Figure 2 The light-transmitting part 300 is a lens, and the extrusion structure 310 of the light-transmitting part 300 is a protrusion integrally formed on the light-transmitting part 300. In other embodiments, the extrusion structure 310 may also be a protrusion added to the light-transmitting part 300.

[0050] Specifically, the second sealant 400 can be injected into the sealing channel 320 after the first sealant 200 has completely or partially solidified.

[0051] Reference Figure 2 and Figure 6 According to some embodiments of this application, the groove wall of the groove 110 includes a first wall surface 111 and a second wall surface 112 disposed opposite to each other. The first wall surface 111 is located on the side of the groove 110 closer to the light source part 500, and the second wall surface 112 is located on the side of the groove 110 away from the light source part 500. The second wall surface 112 is higher than the support surface 113.

[0052] It is understandable that when the first sealant 200 is squeezed into the groove 110 of the extrusion structure 310, the first sealant 200 will spread around. Since the second wall 112 is higher than the support surface 113, the part of the sealing channel 320 between the second wall 112 and the side of the extrusion structure 310 has a longer space, so as to inject more second sealant 400.

[0053] Specifically, refer to Figure 6 A groove 110 is formed at the edge of the support portion 100, and a higher flange 140 is formed at the edge of the support portion 100 so that the groove 110 at the edge has a longer second wall surface 112. Similarly, an extrusion structure 310 is formed at the edge of the light-transmitting portion 300.

[0054] Reference Figure 6 According to some embodiments of this application, the second wall surface 112 is lower than the light-transmitting surface 340 of the light-transmitting portion 300.

[0055] It is understandable that the light-transmitting surface 340 of the light-transmitting part 300 is the side of the light-transmitting part 300 that is away from the light source part 500, and is used to transmit the light emitted by the light source part 500. This makes the second wall surface 112 lower than the light-transmitting surface 340 of the light-transmitting part 300, so as to prevent the second sealant 400 from overflowing onto the light-transmitting surface 340 and affecting the light transmission effect of the light-transmitting part 300.

[0056] Reference Figure 5 According to some embodiments of this application, the first wall surface 111 is lower than the support surface 113, and the light source part 500 is at least partially located on one side of the groove opening of the groove 110.

[0057] Understandably, the first wall 111 is lower, and by positioning part of the light source 500 on one side of the groove opening of the groove 110, the light source 500 can block the first sealant 200 flowing toward the interior of the receiving cavity 330 when the extrusion structure 310 extrudes the first sealant 200 in the groove 110, thus preventing the first sealant 200 from flowing into the receiving cavity 330.

[0058] Specifically, refer to Figure 2 and Figure 5 The light source unit 500 includes a substrate 510 and an LED 520. One side of the substrate 510 is fixedly connected to the support unit 100, and the LED 520 is disposed on the other side. The substrate 510 extends along the support surface 113, and the edge of the substrate 510 extends to one side of the groove 110 and is located above the first wall surface 111. The substrate 510 can block the first sealant 200, preventing the first sealant 200 from entering the receiving cavity 330 and preventing the first sealant 200 from flowing to the side of the substrate 510 with the LED 520, so as to avoid the first sealant 200 affecting the light of the LED 520.

[0059] Reference Figure 1 , Figure 2 and Figure 7 According to some embodiments of this application, the light source module further includes a fixing part 600, which is detachably connected to the light-transmitting part 300 and the support part 100 to fix the light-transmitting part 300 and the support part 100.

[0060] It is understandable that by fixing part 600 limiting light-transmitting part 300 and support part 100, light-transmitting part 300 and support part 100 are tightly connected, and fixing part 600 is detachably connected to light-transmitting part 300 and support part 100 respectively, which facilitates disassembly and assembly.

[0061] According to some embodiments of this application, the fixing part 600 is made of insulating material.

[0062] It is understood that the light source module of this application can be used as an outdoor lighting device. The light source module is installed on the light pole, and the fixing part 600 can be used to connect to the light pole. Since the fixing part 600 is made of insulating material, it can prevent pedestrians from accidentally touching the light pole when the light source module leaks electricity and reduce other safety risks caused by leakage.

[0063] Reference Figure 7 According to some embodiments of this application, the fixing part 600 is located on one side of the opening 321 to cover the opening 321.

[0064] Understandably, the fixing part 600 is located on one side of the opening 321, which can cover the opening 321, thereby preventing the second sealant 400 from overflowing from the opening 321.

[0065] Reference Figure 7 According to some embodiments of this application, the fixing part 600 includes a first fixing structure 610, a second fixing structure 620, and a fastener 630. The first fixing structure 610 and the second fixing structure 620 are connected, and a fixing groove 640 is defined between the first fixing structure 610 and the second fixing structure 620. One end of the light-transmitting part 300 and one end of the support part 100 are engaged in the fixing groove 640. The first fixing structure 610 is located on one side of the opening 321, the second fixing structure 620 abuts against the support part 100, and the fastener 630 passes through the second fixing structure 620 and the support part 100.

[0066] Understandably, one end of the light-transmitting portion 300 and one end of the supporting portion 100 are engaged in the fixing groove 640, and the first fixing structure 610 and the second fixing structure 620 clamp the light-transmitting portion 300 and the supporting portion 100. The first fixing structure 610 is located on one side of the opening 321 to shield the opening 321, and the first fixing structure 610 abuts against the edge of the light-transmitting portion 300 forming the opening 321 and the edge of the supporting portion 100. The second fixing structure 620 abuts against the side of the supporting portion 100 opposite to the light-transmitting portion 300, and the second fixing structure 620 and the supporting portion 100 are fixed by fasteners 630, thereby connecting the light-transmitting portion 300 and the supporting portion 100.

[0067] Specifically, the fastener 630 is a screw, and the fastener 630 is threadedly connected to the second fixing structure 620 and the support 100.

[0068] Reference Figure 2 According to some embodiments of this application, the support portion 100 includes a support plate 120 and a heat dissipation structure 130. One side of the support plate 120 is connected to the light source portion 500, and the other side of the support plate 120 is connected to the heat dissipation structure 130.

[0069] It is understandable that the light source 500 generates heat when emitting light, and the heat dissipation structure 130 can dissipate heat from the light source 500.

[0070] Specifically, the support plate 120 and the heat dissipation structure 130 are integrally formed, and a groove 110 is formed on the side of the support plate 120 away from the heat dissipation structure 130.

[0071] Reference Figure 2 According to some embodiments of this application, the heat dissipation structure 130 includes heat dissipation fins, the sides of which are inclined and close together in a direction away from the support plate 120.

[0072] Understandably, the heat dissipation fins are brought closer together on their two sides in a direction away from the support plate 120, which increases the outer surface area of ​​the heat dissipation fins and improves their heat exchange effect.

[0073] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
