Easily radiated and high-power LED street lamp cap

Abstract

The invention relates to an easily radiated and high-power light emitting diode (LED) street lamp cap. The outer surface of a lamp shell body radiator is provided with a plurality of radiating fins, and the plurality of radiating fins are arranged in parallel strips along the axial direction of the lamp shell body radiator; the inner bottom of the lamp shell body radiator is provided with lug boss mounting faces of different angles, aluminum substrates are arranged on the lug boss mounting faces, LED light sources are arranged on the aluminum substrates, the LED light sources are connected by a printed circuit board, and circular pit lenses are arranged outside the LED light sources; and an upper cover is arranged at the front end of the lamp shell body radiator, and light transmission glass is arranged on the upper cover. The inner bottom of the lamp shell body radiator is provided with the lug boss mounting faces of different angles, so that different assembly modes can be adopted in the LED light sources according to different purposes, requirements of different occasions and different illumination ranges are met, the utilization efficiency of an LED is improved, and the illumination effect of a pavement is improved; and the LED street lamp cap has the advantages of power economization, good radiating and illumination effects, simple structure and the like, and is suitable for outdoor road illumination.

Description

technical field [0001] The invention relates to an LED semiconductor lighting fixture, in particular to an easy-to-dissipate, high-power LED lamp holder for street lamps. Background technique [0002] Traditional street light sources use high-pressure sodium lamps, high-pressure mercury lamps, fluorescent lamps, etc. The disadvantages of this type of light source are short life, poor heat dissipation performance, soft light, and high power consumption, which do not meet the green lighting requirements of energy saving and environmental protection in modern society. With the advancement of electronic technology, lighting fixtures using high-power light-emitting diodes (LEDs) are becoming more and more common, with the advantages of soft light color, low power consumption, and long service life. But because existing LED street lamp adopts high-power LED light source, its calorific value is bigger than general low-power LED, uses for a long time, will directly affect the life-s...

AI Technical Summary

Problems solved by technology

However, because the existing LED street lamps use high-power LED light sources, their heat generation is larger than that of ordinary low-power LEDs. Long-term use will directly affect the life of the LED light source and shorten its life.

Moreover, the LED light source is installed horizontally on the boss. Since most of the LED light sources emit direct light and have good light concentration, the LED light is irradiated at the same angle, which cannot fully illuminate the road, and has not passed a reasonable light distribution design. To achieve the light distribution required for road lighting

It not only affects the lighting effect, but also reduces the use efficiency of LED
