Abstract

The invention belongs to the technical field of illumination, and particularly relates to a beam-combining and beam-splitting illumination system which comprises a plurality of first light source modules, a collimation module, a beam splitting module and a plurality of first beam combining modules. Parallel light beams emitted by the light source module I through the collimation module enter the incident plane of the light splitting module, the angle of the light splitting module is smaller than 30 degrees, the light splitting module is used for emitting the light beams into the incident plane of the beam combining modules I, and the beam combining modules I are used for combining the light beams emitted by the light splitting module and emitting the light beams to the beam combining modules II; according to the invention, the light splitting module adopts a light combination design of less than 30 degrees, so that the processing difficulty of a light combination mirror is reduced, and the cost is reduced. The system has great benefits for light combination of light sources with small dominant wavelength spacing, and the size of the system is greatly reduced by adopting the design of a mixed wave light source.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a beam combining and splitting lighting system. Background technique [0002] As a new type of solid-state lighting source, laser-based white light source has become the new favorite of industrial lighting and road lighting due to its advantages of long viewing distance, good color stability, and high resolution. [0003] Traditional light combining generally adopts multiple single-band light sources plus a 45° angle light combining mirror, which is used for light sources with small band spacing, and the processing of light combining mirrors is relatively difficult, and multiple single-band light sources combine light. This makes the volume of the system larger, and at the same time, the beam combining efficiency is lower. Contents of the invention [0004] The object of the present invention is to provide a beam-combining and splitting lighting system to solve the problems o...
