Abstract

The invention discloses a diffuse reflection LED lamp. The diffuse reflection LED lamp comprises a back lamp shell of which the bottom is in the shape of an arc surface concaved downwards and a surface ring arranged on the back lamp shell in a covering mode; diffuse reflection particles are fully distributed on the inner surface of the back lamp shell, an annular light source installation position is arranged on the back surface of the surface ring, LED light sources are installed on the light source installation position, the light emitting direction of the LED light sources faces the diffuse reflection particles, and light emitted by the LED light sources emits towards the diffuse reflection particles and emits out from light outlets formed in the surface ring through diffuse reflection. The light becomes softer after being subjected to diffuse reflection and cannot dazzle the eyes or generate glare light, and the light-out efficiency is improved. In addition, the LED light sources are hidden, and therefore the lamp appearance is more attractive and novel.
