Abstract

The invention provides a light source system, a projection device and a lighting device. The light source system comprises: a laser light source used for emitting a first-color laser; a supplementarylight source used for emitting the laser as supplementary light; and an optical path selection element including a transmission part used for transmitting the first-color laser, a light path selectionpart used for sequentially reflecting the first-color laser to a first light path or a second light path at any time, and the driving part used for driving the transmission part and the light path selection part to be alternately positioned on the light path of the first color laser; a first wavelength conversion device used for generating second-color fluorescence under the excitation of the first-color laser transmitted along the first light path; and a second wavelength conversion device used for generating third-color fluorescence under the excitation of the first-color laser transmittedalong the second light path, wherein the second-color fluorescence, the third-color fluorescence and the supplementary light are combined with the first-color laser transmitted by the light path selection element and then emitted.

Description

technical field [0001] The present invention relates to the field of projection technology, in particular to a light source system, projection equipment and lighting equipment. 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] Laser fluorescent light source technology is a technology that uses the first color laser to excite phosphors to generate laser light. Usually, blue lasers are used as the first color laser. The phosphors can be yellow phosphors, green phosphors or red phosphors, etc., while The cost of blue laser is relatively low, the electro-optical conversion efficiency is high, and the excitation efficiency of phosphor is high; but the fluorescence spectrum is wide and the color purity is low, so it cannot directly meet the requirements of wide color gamut....
