[0049] The purpose of the present application is to provide a light source module 100 and an LED street lamp 200 using the light source module 100. The light source module 100 emits light when powered on, so that the LED street lamp is used to illuminate roads, streets, parks and other areas.

[0050] According to one aspect of this application, Figures 4 to 6As shown, the light source module 100 provided in the embodiment of the present application includes a heat sink 10, an LED light board 20, a lens 30 and a plurality of latch assemblies 40. The board surface of the heat sink 10 is provided with a plurality of connection structures 11. The LED light board 20 has a light-emitting side 21 and a backlight side, and the light-emitting side 21 and the backlight side are two opposite sides. The backlight side of the LED light board 20 is attached to the board surface of the heat sink 10, so that the heat generated by the LED light board 20 during the light-emitting process can be quickly transferred to the heat sink 10 to achieve the purpose of heat dissipation and cooling. The LED light board 20 is provided with a plurality of first through holes 23, and the plurality of first through holes 23 are arranged one-to-one with the plurality of connection structures 11. The lens 30 covers the light-emitting side 21 of the LED light board 20, and a plurality of optical structures 32 are formed on the lens 30, and the plurality of optical structures 32 are arranged one-to-one with the plurality of LED chips of the LED light board 20. The optical structure 32 adjusts the light emitted by the LED chip, so that the light emitted after the light is transmitted and dimmed by the lens 30 is uniform, soft and non-glaring. The lens 30 is provided with a plurality of second through holes 31, and the plurality of second through holes 31 are arranged one by one corresponding to the plurality of first through holes 23. The latch assembly 40 includes a latch rod 41, and the latch rod 41 is provided with a connection end structure 411 and a manual operation end structure 412. The manual operation end structure 412 can be manually operated by a staff member without the aid of a tool. The connection end structure 411 passes through the second through hole 31 and the first through hole 23 in sequence. The staff member manually screws the manual operation end structure 412 to drive the connection end structure 411 to rotate and connect with the connection structure 11, and the manual operation end structure 412 can block the lens 30, so as to lock the LED light board 20 and the lens 30 to the heat sink 10, so that the backlight side of the LED light board 20 is tightly against the board surface of the heat sink 10.

[0051] Using the light source module 100 provided by the present application, the LED light board 20 is powered on to emit light, the light is transmitted through the lens 30 to be dimmed and radiated out for lighting, and the heat sink 10 can effectively dissipate the heat generated by the LED light board 20. In the light source module 100 provided by the present application, the LED light board 20 and the lens 30 are locked on the heat sink 10 by multiple latch assemblies 40 after being stacked. When installing the light source module 100, the staff only needs to manually rotate the manual operation end structure 412 of the latch rod 41 to drive the connection end structure 411 of the latch rod 41 to rotate and complete the connection with the connection structure 11 on the heat sink 10, and the manual operation end structure 412 can block the lens 30, thereby locking the LED light board 20 and the lens 30 to the heat sink 10. When the LED light board 20 needs to be replaced, the staff only needs to manually rotate the manual operation end structure 412 in the opposite direction to drive the connection end structure 411 to unlock the connection structure 11, so that the LED light board 20 and the lens 30 can be easily and quickly removed from the heat sink 10, and then replaced with a new LED light board 20 and reinstalled. In this way, the staff can complete the disassembly and assembly of the light source module 100 without the help of tools, which greatly improves the work efficiency, reduces the time of the staff working at heights, and reduces the safety hazards of working at heights.

[0052] In addition, in the face of the current LED street lamps, when the staff climbs up to a high place and uses various tools such as screwdrivers and pliers to disassemble and assemble, because the light source module is quite heavy, one staff member is required to hold the light source module to prevent it from falling, and another staff member disassembles and assembles. When facing the LED street lamp 200 that uses the light source module 100 provided by the present application, because the staff can manually disassemble and assemble the light source module 100 without the help of tools, the staff can hold the light source module 100 with one hand and screw the manual operation end structure 412 with the other hand, and the disassembly and assembly work can be completed by one person. In this way, the number of people required to disassemble and assemble the light source module 100 is reduced, the number of personnel is reduced, and labor costs are greatly saved.

[0053] like Figure 5 and Figure 7 As shown, the latch assembly 40 also includes an elastic member 42, which is disposed on the latch rod 41. When the connection end structure 411 is connected to the connection structure 11, the elastic member 42 provides an elastic force toward the heat sink 10 to the lens 30, and then the lens 30 pushes the LED light board 20 toward the heat sink 10 under the action of the elastic force, so that the backlight side of the LED light board 20 is tightly against the board surface of the heat sink 10, thereby improving the heat conduction efficiency. Moreover, under the elastic force of the elastic member 42, the lens 30 and the LED light board 20 can always maintain a stable relative position relative to the heat sink 10, preventing the lens 30 and the LED light board 20 from loosening or shaking relative to the heat sink, and always maintaining stable light output.

[0054] Preferably, the elastic member 42 is a coil spring, which is sleeved on the latch rod 41 and located between the connecting end structure 411 and the manual operation end structure 412. That is, when the connecting end structure 411 is connected to the connecting structure 11, the coil spring is compressed to generate elastic force, so that the two ends of the coil spring abut against the lens 30 and the manual operation end structure 412 respectively. Before the latch assembly 40 is not connected to the connecting structure 11 of the heat sink 10, in order to prevent the coil spring from arbitrarily detaching from the latch rod 41, as shown in FIG. Figure 8 As shown, the latch rod 41 is further provided with a mounting structure 413 close to the manual operation end structure 412, and the coil spring is sleeved on the mounting structure 413. In this way, the mounting structure 413 plays an interference limiting role on the coil spring, so that the coil spring can form an integral module with the latch rod 41 to a certain extent, preventing the coil spring and the latch rod 41 from being separated from each other during the process of moving the latch assembly 40.

[0055] like Figures 5 to 7 , Fig. 9 and Fig.10 As shown, the connection structure 11 includes a fixing block 111 and a receiving groove 112 opened on the plate surface of the heat sink 10. The fixing block 111 is fixedly installed in the receiving groove 112, wherein, as shown in FIG. Fig. 9 and Fig.10 As shown, a screw mounting hole 14 is provided on the fixing block 111, and the screw 13 passes through the screw mounting hole 14 and is screwed and fixed on the heat sink 10, so that the fixing block 111 is completely locked in the receiving groove 112. The fixing block 111 is provided with a first clamping portion 113, and the connecting end structure 411 is configured as a second clamping portion adapted to be clamped with the first clamping portion 113. Therefore, after the connecting end structure 411 passes through the second through hole 31 and the first through hole 23 in sequence, the connecting end structure 411 (i.e., the second clamping portion) extends to the first clamping portion 113, and then the staff manually screws the manual operation end structure 412, which then drives the second clamping portion to rotate and completes the clamping with the first clamping portion 113, thereby compressing the coil spring to generate elastic force, so that the lens 30 and the LED light board 20 can always maintain a stable relative position relative to the heat sink 10 under the elastic force of the coil spring. Furthermore, since the first clamping portion 113 is provided on the fixing block 111, the receiving groove 112 can be provided as a sunken groove, that is, the receiving groove 112 does not need to penetrate the heat sink 10, so that the heat sink 10 can remain relatively intact.

[0056] In other embodiments of the present application, the connection structure 11 is a threaded hole, and the connection end structure 411 is configured as an external thread that is threadedly connected to the threaded hole. When the connection end structure 411 is connected to the connection structure 11, the staff manually screws the manual operation end structure 412, so that the external thread of the connection end structure 411 and the internal thread of the threaded hole are threadedly connected. In this embodiment, the threaded hole is a blind hole, so that the heat sink 10 can remain relatively intact.

[0057] In the light source module 100 provided in the embodiment of the present application, the heat sink 10 is a metal plate, so that the heat sink 10 has good thermal conductivity, so that the heat generated by the LED light board 20 when emitting light can be quickly transferred to the heat sink 10, and the heat dissipation and cooling efficiency is high. The heat sink 10 is formed by metal aluminum or aluminum alloy, and can also be formed by metal copper or copper alloy, which is not limited here. The heat sink 10 of the embodiment of the present application is preferably formed by metal aluminum or aluminum alloy, which is not only light in weight, but also has good thermal conductivity and sufficient strength.

[0058] like Figure 5 As shown, the heat sink 10 is provided with a wiring through hole 12. After the wire passes through the wiring through hole 12, it is smoothly electrically connected to the LED lamp board 20, which facilitates the wiring of the wires.

[0059] According to another aspect of the present application, an LED street lamp 200 is provided, such as Figures 1 to 3 As shown. The LED street lamp 200 includes a shell 210 and the aforementioned light source module 100. The shell 210 is provided with a mounting groove 211 and a mounting end 213. The heat sink 10 of the light source module 100 is arranged on the bottom wall 212 of the mounting groove 211, and the lens 30 of the light source module 100 is arranged opposite to the opening of the mounting groove 211. The LED street lamp 200 is installed and fixed to the street lamp pole as a whole through the mounting end 213. The LED street lamp 200 is used to illuminate roads, streets, parks and other areas. The LED lamp board 20 of the light source module 100 is powered on to emit light, and the light is transmitted through the lens 30 for dimming and emission. The light is radiated from the opening of the mounting groove 211 of the shell 210 for illumination.

[0060] In some embodiments of the present application, Figure 1 and Figure 2 , the heat sink 10 may include but is not limited to a bottom wall 212 that can be fastened to the mounting groove 211 by bolts. Alternatively, in other embodiments of the present application, such as Figure 3As shown, the heat sink 10 is integrally formed on the bottom wall 212 of the mounting groove 211. At this time, the receiving groove 112 is directly opened on the bottom wall 212 of the mounting groove 211 (the other structures of this embodiment are the same as those of the previous embodiment and are not repeated here). In this way, the heat generated by the LED light board 20 when emitting light is transferred to the heat sink 10 and then transferred to other positions of the housing 210, thereby improving the heat dissipation efficiency. Furthermore, a plurality of heat dissipation fins 214 are provided on the back side of the housing 210, such as Figure 1 As shown, the back area of ​​the shell 210 where the heat dissipating fins 214 are located is directly opposite to the heat dissipating plate 10. Therefore, most of the heat received by the heat dissipating plate 10 will be transferred to the heat dissipating fins 214, and then the heat dissipating fins 214 will dissipate the heat to the external air, further improving the heat dissipation efficiency.

[0061] When the LED street lamp 200 is repaired or upgraded by replacing the LED lamp board 20 and the lens 30, the staff only needs to manually rotate the manual operation end structure 412 to drive the connection end structure 411 to unlock the connection structure 11, so that the LED lamp board 20 and the lens 30 can be easily and quickly removed from the heat sink 10, and then replaced with a new LED lamp board 20. When the light source module 100 is reinstalled, the staff still only needs to manually rotate the manual operation end structure 412 of the latch rod 41 to drive the connection end structure 411 of the latch rod 41 to rotate and connect with the connection structure 11 on the heat sink 10, thereby locking the LED lamp board 20 and the lens 30 to the heat sink 10. The staff can complete the disassembly and assembly work without the help of tools, which greatly improves the work efficiency, reduces the time for the staff to work at heights, and reduces the safety hazards of working at heights.

[0062] In order to make the light emitted from the opening of the mounting groove 211 of the housing 210 more uniform and soft, Figure 2 As shown, the LED street lamp 200 also includes a diffuser plate 220, which is connected to the housing 210 and covers the opening of the mounting groove 211. In this way, after the light emitted by the LED lamp board 20 is adjusted for the first time by the optical structure 32 of the lens 30, the light is irradiated to the diffuser plate 220 for propagation, and the light is adjusted again by the diffuser plate 220 for illumination, thereby making the illumination light more uniform, soft, and non-glaring. In addition, the circumferential edge area of ​​the diffuser plate 220 and the opening edge of the mounting groove 211 are sealed by a sealing ring 221, so that the LED street lamp 200 has good dustproof and waterproof performance, meeting the dustproof and waterproof requirements of outdoor lighting fixtures.

[0063] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
