It can be understood that the first wire passing hole 503 can also be formed at any other possible position of the heat dissipation substrate 50.

[0036] According to a preferred embodiment, as shown in Figure 3 A clamping groove 504 is configured to be continuously arranged around the heat dissipation substrate 50 in the circumferential direction of the heat dissipation substrate 50.

[0041] According to a preferred embodiment, as shown in Figure 4 The surface of the light source substrate 20 is also provided with one or more second blind holes 202. The one or more second blind holes 202 respectively correspond to one or more positioning parts 502 (such as positioning pins) on the surface of the heat dissipation substrate 50, so that the one or more positioning parts 502 can respectively penetrate into the corresponding second blind holes 202.

[0042] It can be understood that the surface of the light source substrate 20 can be arranged with multiple sets of second blind holes 202. The multiple sets of second blind holes 202 can be configured to be the same as or different from each other. For example, the inner diameter of one set / group of second blind holes 202 is different from that of another set / group of second blind holes 202. In the embodiment, a pair of second blind holes 202 can be provided. The pair of second blind holes 202 can be arranged on the surface of the two ends of the length direction of the light source substrate 20. The pair of second blind holes 202 correspond to a pair of positioning parts 502 on the surface of the heat dissipation substrate 50. Alternatively, multiple pairs of second blind holes 202 can be arranged at multiple different positions on the surface of the light source substrate 20, but correspond to multiple pairs of positioning parts 502 on the surface of the heat dissipation substrate 50 respectively.

[0043] According to a preferred embodiment, the positioning portion 502 of the surface of the heat dissipation substrate 50 has a length greater than the thickness of the light source substrate 20, so that after passing through the second blind hole 202 on the surface of the light source substrate 20, a portion of the positioning portion 502 is on the side of the light source substrate 20 facing away from the heat dissipation substrate 50, that is, the positioning pin shaft portion protrudes out of the light source substrate 20.

[0044] According to a preferred embodiment, as shown in Figure 4 , a second wire passing hole 203 is formed at a substantially central position of the light source substrate 20.

Generally, the second wire passing hole 203 is formed on the light source substrate 20 in a manner corresponding to the first wire passing hole 503 on the surface of the heat dissipation substrate 50.

[0045] According to a preferred embodiment, as shown in Figure 4 , a second wire passing hole 203 is formed at a substantially central position of the light source substrate 20. The second wire passing hole 203 is configured to allow the power supply wire 7 for powering the light source assembly 2 to pass through to be mechanically and / or electrically connected to the light source assembly 2, such as being electrically connected to the lamp beads 21 on the surface of the light source substrate 20. It can be understood that the second wire passing hole 203 can also be formed at any other possible position of the light source substrate 20. Generally, the second wire passing hole 203 is formed on the light source substrate 20 in a manner corresponding to the first wire passing hole 503 on the surface of the heat dissipation substrate 50.

[0046] According to a preferred embodiment, as shown in Figure 5 , the lens assembly 1 provided by the embodiments of the present application can include a lens substrate 10. A plurality of light-transmitting portions 11 corresponding to the lamp beads 21 on the light source substrate 20 are formed on the lens substrate 10. When the lens substrate 10, the light source substrate 20 and the heat dissipation substrate 50 are combined in sequence from top to bottom, the light-transmitting portions 11 of the lens substrate 10 are configured to allow the light generated by the lamp beads 21 to be emitted.

[0047] According to a preferred embodiment, as shown in Figure 5 , the lens substrate 10 is circumferentially formed with a boss 101 corresponding to the clamping groove 504 of the heat dissipation substrate 50. The boss 101 is configured to extend towards the side of the light source substrate 20 along the thickness direction thereof. When the lens assembly 1 and the heat sink 5 are joined, the boss 101 of the lens substrate 10 is aligned and inserted into the clamping groove 504 of the heat dissipation substrate 50. The clamping groove 504 of the heat dissipation substrate 50 can be pre-filled with a sealing ring 3. When the boss 101 of the lens substrate 10 is joined to the heat dissipation substrate 50 by virtue of the circumferential boss 101, the sealing ring 3 fills the joint gap between the lens substrate 10 and the heat dissipation substrate 50 to prevent water from entering.

[0048] In the embodiment of the present application, the connection between the lens assembly 1 and the heat sink 5 can be achieved only by the adhesive 4. Alternatively, the sealing ring 3 can also be formed by other materials having physical adhesion to cooperate with the adhesive 4 in the positioning blind hole 501 to enhance the connection stability between the lens assembly 1 and the heat sink 5. Thus, preferably, the connection between the lens assembly 1 and the heat sink 5 can be completed by the cooperation of the adhesive 4 and the sealing ring 3 having adhesion. The liquid silicone shown in the embodiment of the present application is only a non-limiting example for disclosure and should not be regarded as a specific limitation of the present application. In other embodiments, the sealing ring 3 can also be a commonly used waterproof gasket.

[0049] According to a preferred embodiment, as shown in Figure 5 The lens substrate 10 is configured with one or more pin columns 102 on the surface thereof.

The one or more pin columns 102 are formed on the lens substrate 10 in a one-to-one correspondence with the one or more positioning blind holes 501 on the surface of the heat dissipation substrate 50 and the one or more through holes 201 on the surface of the light source substrate 20.

[0050] Specifically, when the lens assembly 1 and the heat sink 5 are joined, the lens substrate 10 is joined to the heat dissipation substrate 50 by means of the circumferential boss 101, and at the same time, the one or more pin columns 102 on the surface of the lens substrate 10 are respectively correspondingly passed through the one or more through holes 201 on the surface of the light source substrate 20, so that the one or more pin columns 102 are respectively correspondingly inserted into the one or more positioning blind holes 501 on the surface of the heat dissipation substrate 50, wherein the adhesive 4 is pre-filled in each positioning blind hole 501. The adhesive 4 is extruded by the pin column 102 to bond and fix the lens substrate 10 and the heat dissipation substrate 50.

[0051] According to a preferred embodiment, as shown in Figure 5 The lens substrate 10 is also configured with one or more first blind holes 104 on the surface thereof. The one or more first blind holes 104 correspond respectively to the one or more positioning portions 502 on the surface of the heat dissipation substrate 50 and the one or more second blind holes 202 on the surface of the light source substrate 20, so that each positioning portion 502 can pass through the corresponding second blind hole 202 and first blind hole 104 in sequence, thereby being aligned in the vertical direction to connect the heat sink 5, light source assembly 2 and lens assembly 1 in sequence.

[0052] Preferably, in the embodiment of the present application, a pair of first blind holes 104 can be provided. The pair of first blind holes 104 can be respectively arranged on the surface of the two end portions of the heat dissipation substrate 50 in the length direction. Further, the pair of first blind holes 104 correspond respectively to a pair of positioning portions 502 on the surface of the heat dissipation substrate 50 and a pair of second blind holes 202 on the surface of the light source substrate 20.

[0053] According to a preferred embodiment, as shown in Figure 5 The lens substrate 10 surface is also configured with one or more protrusions 103. The plurality of protrusions 103 are arranged substantially uniformly along the length and / or width direction of the lens substrate 10. For example, the plurality of protrusions 103 can be arranged adjacent to the light-transmitting portion 11 of the lens substrate 10, or between adjacent lens substrates 10. In particular, the protrusions 103 have the function of adjusting the distance between the light distribution unit (i.e. the light-transmitting portion 11) of the lens assembly 1 and the light source module 2, that is, when the lens substrate 10 is assembled onto the light source substrate 20 in a manner that the light-transmitting portion 11 and the lamp bead 21 correspond to each other, the protrusions 103 keep the distance between the lamp bead 21 and the light-transmitting portion 11 at a set or desired distance.

[0054] Referring to Figures 1 to 6 In assembling the light source module provided by the embodiments of the present application, the positioning portion 502 of the heat sink 5 is passed through the second blind hole 202 of the light source assembly 2 to position the light source assembly 2 on the receiving surface of the heat sink 5. Then, the power cord 7 is passed through the output end of the waterproof connector 6, sequentially through the first wire passing hole 503 of the heat sink 5 and the second wire passing hole 203 of the light source assembly 2, and connected to the positive and negative electrode welding positions of the light source assembly 2. The power cord 7 is arranged and tightened, and the waterproof connector 6 is fixed and locked. After functional testing is qualified, the adhesive 4 (such as pressure-sensitive adhesive) is filled in the positioning blind hole 501 on the surface of the heat sink 5, and the sealing rubber ring 3 (such as silicone) is filled in the clamping groove 504 around the heat sink 5. Then, the first blind hole 104 of the lens assembly 1 is aligned and sleeved to the positioning portion 502 of the heat sink 5, the pin column 102 of the lens assembly 1 is inserted into the positioning blind hole 501 of the heat sink 5 through the through hole 201 of the light source assembly 2 and extruded with the adhesive 4, at the same time, the protrusion 101 around the lens assembly 1 is clamped into the clamping groove 504 around the heat sink 5 and extruded with the sealing rubber ring 3, and the lens assembly 1 is compacted with the heat sink 5 as a whole, and the assembly is completed after standing for a set time.

[0055] Alternatively, in other alternative embodiments of the present application, the surface of the heat dissipation substrate 50 can be configured with one or more pin posts 102. The surface of the lens substrate 10 can be configured with one or more positioning blind holes 501 which are shaped to fit the pin posts 102. Thus, when the heat sink 5 and the lens assembly 1 are combined vertically, the one or more pin posts 102 on the surface of the heat dissipation substrate 50 can be correspondingly passed through the one or more through holes 201 on the surface of the light source substrate 20, so as to be correspondingly inserted into the one or more positioning blind holes 501 on the surface of the lens substrate 10, wherein each of the positioning blind holes 501 is pre-filled with the adhesive 4. In other words, the surface of the heat dissipation substrate 50 provided by the present application can be configured with any one of the positioning blind holes 501 and the pin posts 102, and the surface of the lens substrate 10 connected to the heat dissipation substrate 50 can be configured with any other one of the positioning blind holes 501 and the pin posts 102. Therefore, it can be understood that the arrangement of the positioning blind holes 501 and the pin posts 102 as shown in the drawings should not be considered as a specific limitation on the structure of the present application.

[0056] Further, in other alternative embodiments of the present application, the periphery of the heat dissipation substrate 50 can be configured with a boss 101 arranged around the heat dissipation substrate 50. The periphery of the lens substrate 10 can be configured with a clamping groove 504 which is shaped to fit the boss 101. Thus, when the heat sink 5 and the lens assembly 1 are combined vertically, the boss 101 on the periphery of the heat dissipation substrate 50 can be engaged into the clamping groove 504 on the periphery of the lens substrate 10, so as to align and connect the two, wherein the engagement gap between the boss 101 and the clamping groove 504 can be pre-filled with the sealing ring 3.
