Abstract
Description
Technical field:
[0001] The utility model belongs to the technical field of lamps, and in particular relates to a universal LED lamp module. Background technology:
[0002] Streetlights, as a crucial urban lighting system, play a vital role in ensuring traffic safety. Traditional streetlights often use high-pressure sodium lamps. From a lighting professional perspective, these lamps have low overall luminous efficacy, high energy consumption, and a relatively short lifespan. LED streetlights, with their advantages of energy saving, environmental friendliness, long lifespan, and strong controllability, have gained widespread adoption in urban lighting. To facilitate maintenance and retrofitting, many LED streetlight accessories utilize a modular design, assembling interchangeable, universal LED lamp modules. Conventional lamp modules typically consist of components such as a heat sink, light source, lens assembly, and cables.
[0003] Currently, most LED lighting modules of this type have an IP65 protection rating, primarily requiring protection at the wiring outlet on the back of the module and the lens assembly fitting on the front. When the module is exposed or the matching lamp housing is not sealed, the sealing rubber ring at the wiring outlet on the back of the module will be directly exposed to the sun and rain. After a few years, it will age, causing rainwater, snow, and other water to flow from the wiring outlet on the back to the light source on the front of the module, causing the lamp to fail. Furthermore, the power of a single LED lighting module is typically between 30W and 60W. If the entire lamp needs to be 300W, 5 to 10 modules need to be installed inside the lamp housing, requiring a lamp housing large enough to accommodate the modules. This leads to high manufacturing costs for the lamp housing and the high cost of manufacturing multiple modules. Summary of the invention:
[0004] The technical problem to be solved by the utility model is to provide a universal LED lamp module, which has a high protection level and a long service life.
[0005] In order to solve the above technical problems, the universal LED lamp module of the present invention includes a radiator body, a light source assembly, and a power cord; it is characterized in that it also includes a waterproof connector and a sealing assembly; the radiator body is processed with a wire hole; one end of the power cord passes through the wire hole and is connected to the light source in the light source assembly, and the other end is connected to the external power supply line through a waterproof connector; the sealing assembly includes a sealing column, an O-ring and a waterproof hexagonal screw; the sealing column is tightly clamped on the power cord to seal the gap between the power cord and the waterproof hexagonal screw; the O-ring is tightly clamped on the waterproof hexagonal screw to seal the gap between the waterproof hexagonal screw and the wire hole.
[0006] Further, the middle of the heat sink body has a phase change cavity, an air inlet hole at the top of the phase change cavity is equipped with a sealing screw, the bottom opening is blocked by a bottom cover plate, and the top surface of the bottom cover plate has a micro groove group.
[0007] Further, the side surface of the bottom cover plate is press-sealed with the inner wall bottom of the phase change cavity through two layers of barb steps.
[0008] Further, the lower bottom plate of the heat sink body is an integral structure with the fins on the two sides of the phase change cavity, and the bottom plate is provided with heat dissipation convection holes parallel to each other at positions corresponding to intervals between the fins.
[0009] Further, the two sides of the bottom plate are provided with bending connecting parts.
[0010] Further, the heat sink body is provided with a sunken structure near the phase change cavity, and a wire hole is formed below the sunken structure.
[0011] Further, the power line passes through a waterproof hexagonal screw and then is connected with a waterproof connector through the gap between the adjacent two fins.
[0012] Further, the utility model also includes a baffle, a clamping groove is arranged on the inner wall of one side of the sunken structure, the baffle is a right-angle metal part, the vertical part of the baffle is inserted into the clamping groove, and the horizontal part covers the top opening of the sunken structure.
[0013] The sunken structure is square or rectangular, and the clamping groove is arranged on the inner wall close to the phase change cavity.
[0014] Further, the light source assembly comprises a light source, a rubber ring, a lens, and a pressing frame, the light source is fixed below the bottom cover plate, the rubber ring is wrapped around the edge of the lens, the lens is fixed below the bottom cover plate and covers the light source through the pressing frame, and the gap among the bottom cover plate, the lens and the pressing frame is sealed through the rubber ring.
[0015] Beneficial effects:
[0016] 1. The back wire inlet of the LED lamp module adopts a waterproof design in the form of a sealing assembly, and the protection level can reach IP67.
[0017] 2. The waterproof screw sealing position on the back of the LED lamp module adopts a sunken design, the wire outlet of the whole module is lower than the overall height of the back of the module, and the module can be assembled into more small-space lamp housings.
[0018] 3. A convenient baffle shielding structure is added above the waterproof screw sealing position on the back, when the module is used in a naked or semi-naked manner, the problem of water entering the module caused by the aging of the sealing ring after being exposed to the sun and rain for a long time can be effectively solved, and the service life of the LED lamp module is greatly prolonged.
[0019] 4. The phase change cavity is arranged at the middle part of the radiator body, the composite phase change heat dissipation technology is adopted, and reasonable heat dissipation convection holes are combined, so that the heat dissipation capacity of the LED module is greatly improved, and the power of a single general LED lamp module can reach 150W, which is much higher than most similar products.
[0020] 5. The existing few similar modules with phase change cavities need to seal both sides of the phase change cavity, need to machine two cover plates and two side openings of the phase change cavity, and need to fill sealing glue during sealing; the utility model only needs to process double-layer barb steps on the side wall of the bottom cover plate, then press the double-layer barb steps into the bottom opening of the phase change cavity, the double-layer barb steps are deformed, and the gap between the bottom cover plate and the inner wall of the phase change cavity is filled, so that the sealing effect of the phase change cavity is achieved.
