Abstract

The invention discloses a lamp, which comprises a housing, an optical system and a light source, the optical system is installed in the housing, and the light emitted by the light source arranged in the optical system propagates forward after being reflected by the optical system; The optical system includes a back reflective surface, and a part of the back reflective surface is a non-smooth surface, or a non-smooth layer is attached to a part of the smooth back reflective surface; wherein, the light emitted by the light source is reflected by the back reflective surface and then goes forward spread. The present invention overcomes the existing technical prejudice. When applying the "wash" lighting method, the illumination of the "dark area" near the illuminated surface is improved by performing non-smooth treatment on the rear reflection surface in the optical system, thereby improving the illumination of the illuminated surface. Uniformity of illumination.

Description

technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to a lamp. Background technique [0002] In lighting engineering applications, "surface" lighting is an important lighting method. When evaluating the quality of lighting on a surface, a commonly used index is uniformity, that is, to examine whether the brightness of each point on the surface is consistent. The lower the uniformity, the "more obvious the difference between light and dark" seen by the eye. In order to improve the uniformity of illumination, it is necessary to reduce the dark area, expand the range of the bright area, and reduce the light-dark difference between the bright area and the dark area. The commonly used methods are: increase the distance from the lamp to the illuminated surface, expand the beam angle and reduce the The distance to the illuminated surface narrows the beam angle. Among them, the method of reducing the distance from the lamp to...
