Abstract

The invention provides a light source system and illumination equipment. The light source system comprises a light emitting module, a wavelength conversion device and a compensation device, wherein the light emitting module is used for emitting first light along a first light path and second light along a second light path; the wavelength conversion device is used for receiving the first light andemitting stimulated light with the color which is different from that of the first light; the compensation device is used for guiding the second light and adjusting the light emitting strength distribution of the second light; the second light emitted by the compensation device is roughly the same as the light emitting strength distribution of the stimulated light; and the stimulated light and the second light emitted by the compensation device are compounded to generate third light emitted by the light source system. The light emitting strength distribution of the first light and the secondlight in the third light is roughly the same and the colors of illumination light spots are uniform.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a light source system and lighting equipment thereof. Background technique [0002] This section is intended to provide a background or context to a detailed description of the invention that is recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] With the continuous increase in brightness requirements for special lighting such as stage lights, the integrated LED lighting source has encountered a bottleneck, and cannot maintain an acceptable volume while increasing the total brightness of the lamp. Therefore, some R&D personnel have turned to other technical approaches to solve the compatibility problem of light source brightness and volume. In particular, the application of laser-excited remote phosphor technology in this type of lighting device has attracted more and more attention. [0004] Generally, by gui...
