Reflector and lighting device

Abstract

The invention discloses a reflector and an illuminating device. The reflector comprises a first reflecting surface, a second reflecting surface and a third reflecting surface, wherein the first reflecting surface, the second reflecting surface and the third reflecting surface are sequentially and smoothly connected and all adopt a curved surface structure; the first reflecting surface is close toa wall surface; the third reflecting surface is farthest away from the wall surface; and when the light of a light source irradiates downwards to the reflector from the position above the second reflecting surface, the reflector uniformly reflects the light to the wall surface. According to the invention, the reflector is asymmetrically designed in a sectional manner, and after the light of the light source is irradiated to the reflector, the light is secondarily distributed through the reflector, so that the light uniformly covers the wall surface, the problem of glare caused by light distribution by using a lens is avoided, the illumination comfort and the illumination effect are improved, and the reflector can be widely applied to the technical field of illumination.

Description

technical field [0001] The invention relates to the technical field of illumination, in particular to a reflector and an illumination device. Background technique [0002] With the rapid development of landscape lighting, LED wall washer has gradually become popular and has become one of the most important landscape lighting fixtures. Conventional LED wall washers generally use lenses to distribute the light of the lamps, and the efficiency of the lenses can reach about 85%-90%. The frosted surface makes the light passing through the lens diffuse randomly, causing glare. If the wall washer is installed in a place where people pass by, the glare will cause discomfort to the human eye and cause environmental light pollution. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a reflector and an illuminating device that can irradiate light evenly to the wall and avoid glare.
