Abstract

The invention relates to a lighting device. The lighting device comprises a supporting part, at least one first light source which is positioned on the supporting part, and at least one second light source which is positioned on the supporting part, wherein the first light source has first light distribution, the second light source has second light distribution, and the first light distribution is different from the second light distribution.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a lighting device. Background technique [0002] The light distribution provided by the light source is usually constant. However, in order to meet different lighting needs, it is necessary to provide lighting devices with various light distributions. Therefore, in order to provide various light distributions, in the prior art, additional optical elements independent of the light source must be used, such as lenses, reflectors, diffusers, etc., to change the optical path of the light emitted from the light source. [0003] The Chinese patent application with publication number CN101438096 provides a specific implementation of the above-mentioned prior art, including: a lighting device, which includes a light source; Wet optical element; drive means arranged to operate said optical element between at least two predetermined states, said states being adapted to result in refract...
