Abstract

The invention discloses an optical system for illumination with asymmetrical light distribution. The optical system includes a back reflection surface, and part of the back reflection surface is a non-smooth surface, or a part of the smooth back reflection surface is attached with a Non-smooth layer; the light emitted by the light source is reflected by the back reflector and propagates forward. The present invention overcomes the existing technical prejudice. When the "wash" lighting method is applied, the illuminance of the "dark area" near the irradiated surface is improved by performing non-smooth treatment on the back reflective surface, thereby improving the illuminance uniformity of the irradiated surface. Spend.

Description

technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to an optical system for lighting with asymmetrical light distribution. 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. Such as figure 1 with figure 2 As shown, the illuminated surface in the figure is the facade, the lamp is a certain distance away from the facade, and the light emitted by the lamp is concentrated in the beam (note: the two lines indicating the beam in the figure are not the light and dark boundaries of the light. The actual distance of the lamp in all directions Light is distributed according to the lig...
