High-power LED lamp with remote-projection capacity

Abstract

The invention relates to an LED lamp, in particular to a high-power LED lamp with remote-projection capacity. The high-power LED lamp with the remote-projection capacity at least comprises a lampshade and an LED lamp body, and is characterized in that the LED lamp body is located in the center of a reflective paraboloid of the lampshade and is connected with a threaded lamp holder of the lampshade; the LED lamp body at least comprises a supporting body and a lamp cap, LEDs in serial connection or in parallel connection or in serial-parallel connection are distributed on the periphery of the supporting body, and the LEDs distributed on the periphery of the supporting body are wrapped into a whole through fluorescent materials; the LEDs in serial connection or in parallel connection or in serial-parallel connection emit light after being driven by a power supply, and after emitting the light, light emitted by the LEDs in serial connection or in parallel connection or in serial-parallel connection are converted into colors as needed through the fluorescent materials; the fluorescent materials are fluorescent glue. The high-power LED lamp with the remote-projection capacity has the advantages of being good in process, low in cost and high in power.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a high-power LED lamp with long-distance projection capability. Background technique [0002] Metal halide lamp is one of the most excellent electric light sources in the world. It has high luminous efficiency (65~140lm / w), long life (5000~20000h), good color rendering (Ra65~95), compact structure, stable performance, etc. features. It combines the advantages of fluorescent lamps, high-pressure mercury lamps, and high-pressure sodium lamps, and overcomes the defects of these lamps. The metal halide lamp brings together the main advantages of gas discharge light sources. In particular, the three advantages of high luminous efficiency, long life, and good light color. Therefore, metal halide lamps have developed rapidly and are used more and more widely. Metal halide lamps on the market are the same as other gas discharge lamps. Mercury is contained in the filling of the lamp. Mercury is a poisonou...

AI Technical Summary

Problems solved by technology

[0006] When multiple LEDs are connected in series or in parallel, each lamp should have a good radiator to dissipate heat to ensure the life of the LED. Due to the scattered distance, improving the overall long-range projection capability requires a good optical lens, which not only increases the cost, but also makes the Process complexity

[0007] The COB process can effectively improve the above problems, but it is very difficult to achieve the effect of a metal halide lamp with a single lens

The lens group increases the cost again
