Environment friendly high-power LED street lamp

Abstract

The invention relates to the technical field of material science, optics and electronics, in particular to an environment friendly high-power LED (light-emitting diode) street lamp, i.e., a lamp using a high-power LED as the light source. The high-power LED street lamp comprises a housing, wherein the front and rear ends of the housing are respectively connected with a front end cover and a rear end cover; a drive power source is arranged in the front end cover; a mounting hole is formed in the middle of the rear end cover; a plurality of convection holes are formed at the bottom of the front end cover; a plurality of radiating fins are fixed at the upper part of the housing; grooves are respectively formed on two sides of the lower part of the housing; arc-shaped toughened glass is hermetically connected in the two grooves; reflection lampshades in matrix arrangement are arranged between the housing and the toughened glass; the reflection lampshades are fixed in the housing via fixing plates; the outer end of each reflection lampshade is rectangle-shaped and open-ended; lenses are arranged in each reflection lampshade; and a high-power LED bulb is arranged in each lens. The high-power LED street lamp of the invention has the advantages of high luminous efficiency, long service life, pollution-free application, dazzling prevention, good heat-dissipation effect and significant water-resisting and dust-resisting effects.

Description

technical field [0001] The invention relates to the technical fields of material science, optics, electronics and the like, in particular to a lamp using a high-power LED as a light source. Background technique [0002] With the development and maturity of LED technology, the current 1-3W white light power LED has entered the stage of stable batch industrialization, the technology with a luminous flux of 100Lm / W has been very stable, and 160Lm / W is also being popularized in the market. LED street lamps use chips with the highest brightness and high stability today, which have the advantages of high luminous efficiency, long service life, and no pollution. The luminous efficiency of LED white light has far exceeded that of ordinary incandescent lamps, while ordinary lighting has disadvantages such as large power consumption, high working voltage, dazzling, stroboscopic, ultraviolet radiation, long start-up time, and short service life. . As the government pays more and more...

AI Technical Summary

Problems solved by technology

[0003] The currently disclosed LED lighting products or design schemes have the following defects in summary: 1. The utilization rate of light energy is low; 2. It is easy to produce glare and light spots; 3. The heat dissipation effect is not good, which shortens the service life of LEDs.
