Embodiment Construction

[0018] Embodiment 1 of radiator for LED lamp is as figure 1 As shown in -5: the radiator includes a radiator body with a mounting surface 16 at the bottom. The heat sink body is provided with a plurality of heat dissipation holes penetrating the heat sink body in the vertical direction on the periphery of the mounting surface, and each heat dissipation hole is vertically arranged. The bottom of the cooling holes adjacent to the installation surface is connected with a splash-proof tube 11. In this embodiment, the cooling holes are arranged on the left and right sides of the installation surface, and the cooling holes on the left side of the installation surface are the first cooling holes and 5 are located at the second. The second heat dissipation hole 6 on the right side of the first heat dissipation hole, the second heat dissipation hole 6 is a strip-shaped heat dissipation hole with a length extending along the front and rear direction, there are multiple first heat dissi...

Abstract

The invention relates to a radiator for an LED lamp. The radiator for the LED lamp comprises a radiator body, and a mounting surface is arranged at the bottom of the radiator body. The radiator body is provided with a plurality of radiating holes on the periphery of the mounting surface, and the radiating holes penetrate through the radiator body in the vertical direction. The bottom of the radiating hole adjacent to the mounting surface communicates with a splash-proof barrel. The side, away from the mounting surface, of the splash-proof barrel is hinged to the radiator body. The side, close to the mounting surface, of the splash-proof barrel is connected with the radiator body through a corrugated pipe. The radiator body is movably provided with a water collecting tank in a vertically guiding mode, and the upper end of the water collecting tank is open. A water collecting tank return spring is arranged between the water collecting tank and the radiator body. A transmission mechanism is arranged between the water collecting tank and the splash-proof barrel and is used for driving the splash-proof barrel to swing towards the side away from the mounting surface after the water collecting tank collects water and moves downwards. The problem that rainwater possibly splashes onto a mounting surface via radiating holes nearby the mounting surface in the prior art is solved.

Description

technical field [0001] The invention relates to a heat sink for LED lamps in the lighting field. Background technique [0002] With its own excellent characteristics, LED lamps have become more and more popular nowadays. As we all know, high heat generation is an important problem of LED lamps, so each LED lamp needs to be equipped with a suitable radiator. The performance of the radiator directly affects the performance and service life of an LED lamp. For special LED lamps that require outdoor use, there are more special requirements for the radiator structure. , [0003] Existing LED lamps for outdoor use are disclosed in Chinese patent CN103148468B "A Honeycomb Blade Radiator and LED Lamp Group for Hollow Shaft Conductive Modular LED Lamps", which discloses a honeycomb blade radiator. Including the radiator body, the bottom surface of the radiator body is provided with a mounting surface for installing the LED light source, and the periphery of the radiator body is pr...
