Anti-dazzle high-efficiency LED (Light Emitting Diode) lamp

Abstract

The invention discloses an anti-dazzle high-efficiency LED (Light Emitting Diode) lamp which comprises an LED light source and a lamp back plate, wherein a diffuse reflection layer is arranged on the inner surface of the lamp back plate; an arc top surface, a first inner lateral surface and a second inner lateral surface are arranged on the lamp back plate; the first inner lateral surface and the second inner lateral surface are respectively connected with two end parts of the arc top surface; a first LED lamp strip and a second LED lamp strip are arranged on the LED light source; the first LED lamp strip is fixedly arranged on the first inner lateral surface; the second LED lamp strip is fixedly arranged on the second inner lateral surface; in addition, a mirror surface reflector is fixedly connected to the inner lateral surface by corresponding to each LED lamp strip; and the LED lamp strip is arranged between the arc top surface and the mirror surface reflector corresponding to the arc top surface. The anti-dazzle high-efficiency LED lamp disclosed by the invention has the advantages ofs less optical loss, high utilization rate of light and uniformity in brightness in the use process; and meanwhile, the dazzle of the light source is avoided.

Description

technical field [0001] The invention relates to a lighting device, in particular to an anti-glare and high-efficiency LED lamp. Background technique [0002] At present, the brightness of LED is increasing with the increase of luminous flux, and the brightness has exceeded 1000000cd / m2. LED light source will have visual tingling. [0003] Such as figure 1 As shown, the current solution to the high brightness of LED lamps is to hide the LED light source 2 fixed on the substrate 3, and use the high-reflectivity diffuse reflection material 1 to reflect and mix the light emitted by it multiple times, and then diffusely emit it from the surface of the lamp. However, this solution has the following disadvantages: [0004] 1) The interior of the lamp cavity is all diffuse reflection materials, even if the reflectance of the diffuse reflection materials is high, the infinite number of reflections will greatly reduce the luminous efficiency of the lamp; [0005] 2) The distance b...

AI Technical Summary

Problems solved by technology

[0004] 1) The interior of the lamp cavity is all diffuse reflection materials, even if the reflectance of the diffuse reflection materials is high, the infinite number of reflections will greatly reduce the luminous efficiency of the lamp;

[0005] 2) The distance between the LED and the diffuse reflection surface is too close, which usually causes the diffuse reflection light to be reflected to the LED or the LED aluminum substrate to be absorbed;

[0006] 3) The reflective surface close to the LED side will be too bright after being irradiated by the LED. When looking at the lamp from the outside of the lamp, there are two bright stripes distributed inside the lamp, which reduces the overall brightness uniformity effect of the lamp

[0007] 4) Because the LED itself is inherently lambertain-type light emitting, no matter how large θ is, the light distribution on the reflector cannot achieve high uniformity
