Light-emitting diode (LED) high-roof lamp

Abstract

The invention discloses a light-emitting diode (LED) high-roof lamp, which comprises a driver, a radiator assembly and a light source assembly, wherein the radiator assembly has a bowl-shaped structure; radiating fins of the radiator assembly are arranged in a circumferential array and are buckled mutually to form a bowl wall frame; and the light source assembly has an integrally-encapsulated structure, is fixed to a bowl abdomen enclosed by the bowl wall frame and is electrically connected with the driver fixed to the bowl bottom of the bowl-shaped structure in a movable mode. According to the LED high-roof lamp, due to the utilization of a radiating structure of combining a heat conduction pipe and the radiating fins, a good radiating effect is ensured, and both the light source assembly and the radiator assembly are easy to disassemble and replace.

Description

technical field [0001] The invention belongs to the field of semiconductor lighting and relates to an LED (light emitting diode) high bay lamp. Background technique [0002] The light sources commonly used in current high bay lighting fixtures are high-pressure sodium lamps or metal halide lamps, which to a certain extent have the problem of uneven illumination. With the continuous advancement of human lighting technology, the industry has gradually begun to use LEDs as high-bay light sources. As a new type of green and high-efficiency semiconductor light source, LED has the following advantages and characteristics: high luminous efficiency, low reflection loss of lamps, energy saving, low-voltage safety, directional light emission is conducive to the design of light distribution of lamps, no stroboscopic phenomenon, long service life, etc. Wait. [0003] However, heat dissipation has always been one of the key problems to be solved for LED lamps (including LED high bay li...

AI Technical Summary

Problems solved by technology

[0004] However, at present, most manufacturers only consider meeting the requirements of LED light efficiency and brightness when designing LED high-bay lights, but do not consider the heat dissipation and maintenance of high-power LED high-bay lights in practical applications.

This will cause the heat generated by the LED light source to be unable to be exported smoothly during the use of the lamp, so that the junction temperature of the LED light source will increase rapidly, the light decay will accelerate, and the luminous flux will drop sharply.

Not only affects the lighting effect, but also greatly reduces the service life of LED lamps
