[0002] High-power LED laser light source lamps refer to lighting fixtures that use high-power LED chips and laser technology as light sources. Their power range is typically above 50W, and can even reach several hundred watts. These lamps use special optical designs and driving circuits to efficiently convert the light energy of LEDs or lasers into the light required for illumination.

[0003] Currently, waterproof lighting fixtures using high-power LED laser light sources generate a large amount of heat with uneven distribution, making traditional single-sided waterproof heat sinks inadequate for heat dissipation. The unique shape and large size of laser light sources significantly increase the complexity of waterproofing the heat sink's structure and assembly. In the market for lighter, faster, and smaller stage lighting and outdoor lighting, simply relying on bulky materials or reduced power in heat sinks is no longer sufficient. Utility Model Content

By combining two waterproof heat sinks, a frame is formed that encloses the light source in a waterproof enclosure, allowing heat dissipation to occur on all sides of the enclosure. This solves the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-9 In this embodiment of the present invention, a high-efficiency and compact waterproof heat dissipation structure for a high-power laser light source includes a waterproof cover 5 for the light source, the inner side of which is provided with a space for placing an LED laser light source 1; a light source fixing plate 2 is provided on one side of the waterproof cover 5; and a waterproof heat sink 3 and a waterproof heat sink 4 are provided on the outer side of the waterproof cover 5, with the waterproof cover 5 located between the waterproof heat sink 3 and the waterproof heat sink 4.

[0029] The space inside the waterproof cover 5 for placing the LED laser light source 1 is the same shape as the LED laser light source 1; the light source fixing plate 2 is provided with an opening for the light emitted from the LED laser light source 1 to pass through;

[0030] More specifically, the waterproof cover 5 of the light source is provided with a square waterproof rubber ring 8 near the second waterproof radiator 4, and both the waterproof cover 5 of the light source and the second waterproof radiator 4 are provided with grooves for embedding the square waterproof rubber ring 8; a U-shaped waterproof rubber ring 7 is embedded on the side of the waterproof cover 5 away from the second waterproof radiator 4, and the side of the U-shaped waterproof rubber ring 7 away from the waterproof cover 5 of the light source is in contact with the inner wall of the first waterproof radiator 3; a waterproof rubber ring 6 of the light source fixing plate is embedded on the side of the waterproof cover 5 of the light source near the light source fixing plate 2, and the waterproof rubber ring 6 of the light source fixing plate is in contact with the side of the light source fixing plate 2 near the waterproof cover 5 of the light source.

[0031] By adopting the above technical solution, the waterproof cover 5 of the light source is placed between the waterproof heat sink 3 and the waterproof heat sink 4. The two heat sinks dissipate heat from different sides simultaneously to the LED laser light source 1 inside the waterproof cover 5, which significantly increases the heat dissipation area and effectively solves the problem of insufficient heat dissipation efficiency of traditional single-sided heat sinks. This ensures that the heat generated by the high-power LED laser light source can be dissipated quickly and evenly, maintaining the light source at a suitable working temperature and improving the stability and service life of the lamp.

[0032] In this embodiment, the light source fixing plate 2 is fixedly connected to the light source waterproof cover 5 by a plurality of cross-head screws 13, and the light source fixing plate 2 is provided with through holes for the cross-head screws 13 to pass through, and the light source waterproof cover 5 is provided with threaded holes for threaded connection with the cross-head screws 13.

[0033] Each of the aforementioned cross-head screws 13 is coaxially fitted with a light source fixing plate O-ring 9. One side of the light source fixing plate O-ring 9 is in contact with the light source fixing plate 2, and the other side of the light source fixing plate O-ring 9 is in contact with the nut of the cross-head screw 13.

[0034] As a further explanation of the above embodiment, at the connection between the light source fixing plate 2 and the light source waterproof cover 5, the tightening force of the cross-head screw 13 can tightly press the O-ring 9 of the light source fixing plate between the light source fixing plate 2 and the screw nut, thereby forming an effective seal at the screw penetration point, preventing moisture or dust from seeping in from this gap, further enhancing the sealing performance of the connection between the light source fixing plate 2 and the light source waterproof cover 5. Together with the waterproof rubber ring 6 of the light source fixing plate, it constitutes a double waterproof guarantee for the connection surface, ensuring the waterproof reliability of the front opening area of ​​the LED laser light source 1.

[0035] The waterproof radiator 2 4 is fixedly connected to the light source waterproof cover 5 by a plurality of cross-head screws 12, and the waterproof radiator 2 4 is provided with through holes for the cross-head screws 12 to pass through. The end of the light source waterproof cover 5 near the waterproof radiator 2 4 is provided with a threaded hole for threaded connection with the cross-head screws 12. Each of the plurality of cross-head screws 12 is coaxially fitted with a waterproof gasket 11. One side of the waterproof gasket 11 is in contact with the outer wall of the light source waterproof cover 5, and the other side of the waterproof gasket 11 is in contact with the nut of the cross-head screw 12.

[0036] Furthermore, in the connection between the waterproof radiator 2 4 and the light source waterproof cover 5, the cross-head screw 12 passes through the through hole of the waterproof radiator 2 4 and is tightened into the threaded hole of the light source waterproof cover 5. During this process, the waterproof gasket 11, coaxially fitted on the cross-head screw 12, is tightly clamped by the screw and nut against the outer wall of the light source waterproof cover 5. The waterproof gasket 11 is made of elastic waterproof material, and its design can effectively fill the gap between the screw head and the surface of the radiator, preventing moisture from entering along the gap between the screw rod and the inner wall of the through hole. Together with the square waterproof rubber ring 8, it forms a multi-layer waterproof structure combining screw sealing and overall surface sealing at the connection surface, further improving the waterproof performance of the connection between the waterproof radiator 2 4 and the light source waterproof cover 5, and ensuring effective sealing from the rear end of the light source waterproof cover 5.

[0037] The waterproof radiator 3 is fixedly connected to the middle of the end of the waterproof cover 5 away from the waterproof radiator 4 by a plurality of cross-head screws 14. The four corners of the waterproof radiator 3 are fixedly connected to the four corners of the end of the waterproof cover 5 away from the waterproof radiator 4 by hex screws 15. The waterproof radiator 3 is provided with a plurality of through holes for the cross-head screws 14 and hex screws 15 to pass through. The waterproof cover 5 is provided with threaded holes for threaded connection with the cross-head screws 14 and hex screws 15.

[0038] Each of the aforementioned cross-head screws 14 has a heat sink O-ring 10 coaxially fitted on it. One side of the heat sink O-ring 10 is in contact with the light source waterproof cover 5, and the other side of the heat sink O-ring 10 is in contact with the nut of the cross-head screw 14.

[0039] By adopting the above technical solution, U-shaped waterproof rubber rings 7, square waterproof rubber rings 8, and O-rings 9 of the light source fixing plate are respectively installed at the connection points between the waterproof cover 5 of the light source and the waterproof radiator 1 3, the waterproof radiator 2 4, and the light source fixing plate 2. Through a specific groove design and screw fixing structure, the rubber rings can fit tightly together to form multiple waterproof barriers, effectively preventing moisture, dust and other impurities from entering the interior of the light source. This ensures the reliable operation of the lamp in humid environments such as outdoors, achieving the dual functions of efficient heat dissipation and reliable waterproofing. Moreover, the overall structure adopts a modular design, and the components are fixed and connected by screws, making the assembly and disassembly process convenient and conducive to production, installation and later maintenance.

[0040] The working principle of this utility model is as follows: When the LED laser light source 1 is working, the heat it generates is first transferred to the inner wall of the waterproof cover 5 that matches its shape. The waterproof cover 5 acts as an intermediate carrier for heat transfer, quickly conducting the heat to the waterproof heat sink 3 and the waterproof heat sink 4 on its outer side. Since the waterproof cover 5 is located between the two heat sinks, the heat can diffuse from multiple sides of the waterproof cover 5 to the two heat sinks simultaneously, greatly improving the heat transfer efficiency. The waterproof heat sink 3 and the waterproof heat sink 4 themselves have a large heat dissipation surface area, which can quickly dissipate the absorbed heat to the surrounding environment, thereby continuously reducing the internal temperature of the waterproof cover 5 and ensuring that the LED laser light source 1 works stably within a suitable temperature range.

[0041] In terms of waterproofing, the U-shaped waterproof rubber ring 7 between the light source waterproof cover 5 and the waterproof radiator 3 is tightly fitted to the side of the light source waterproof cover 5 by the compression of the waterproof radiator 3, effectively blocking water intrusion from that direction; the square waterproof rubber ring 8 between the light source waterproof cover 5 and the waterproof radiator 4 is embedded in the corresponding grooves of the two, and a tight seal is achieved by the tightening force of the cross-head screw 12; the light source fixing plate waterproof rubber ring 6 between the light source fixing plate 2 and the light source waterproof cover 5, and the light source fixing plate O-ring 9 on the cross-head screw 13, together ensure the waterproof performance of the opening at the front end of the light source; at the same time, the waterproof gasket 11 on the cross-head screw 12 and the radiator O-ring 10 on the cross-head screw 14 further seal the screw connection, preventing water from seeping in along the screw gaps; through this series of mutually cooperating heat dissipation paths and multiple waterproof barriers, this utility model achieves efficient heat dissipation while ensuring the long-term reliable operation of the LED laser light source 1 in complex environments.
