Abstract

A light distribution module configured to control light distribution of a light source includes a lens and an optical cover. The lens has a first light-incident surface, a first light-emitting surfaceopposite to the first light-incident surface, and an accommodating recess located at a side of the first light-incident surface, wherein the accommodating recess is configured to contain the light source. The optical cover covers the lens and has a second light-incident surface and a second light-emitting surface opposite to the second light-incident surface, wherein the second light-incident surface is located between the first light-emitting surface and the second light-emitting surface, and the second light-incident surface has a plurality of sub-curved surfaces. Boundaries between adjacent sub-curved surfaces are bent-shaped with respect to the adjacent sub-curved surfaces.

Description

technical field [0001] The invention relates to an optical module, and in particular to a light distribution module. Background technique [0002] In the design of traditional lighting devices, the light source is arranged on the optical housing to generate the required light shape. For lighting devices used for road lighting, in order to comply with lighting device installation regulations in different countries and different lighting requirements in different regions, the same lighting device often needs to design several or even dozens of optical housings to meet the requirements. Regulations and regional lighting needs. [0003] However, lighting fixtures for road lighting are often time-consuming and costly to develop. Furthermore, each additional lighting device also means an additional maintenance cost. Therefore, for manufacturers of lighting devices for road lighting, there is an urgent need for a lighting device that can reduce the number of developments of ligh...
