Light source system

Abstract

A light source system comprises a light source, a light splitting and combining assembly, a scattering assembly and a dodging element; the light source comprises a plurality of laser diodes or laser diode arrays and is used for generating laser, the laser comprises at least first wavelength light and second wavelength light, and the first wavelength light and the second wavelength light are different in color or wavelength; the light splitting and combining assembly is used for combining the laser to form a combined light beam; the scattering assembly is used for scattering and dodging the combined light beam, the scattering assembly comprises a first scattering element and a second scattering element, and the first scattering element and the second scattering element are independently arranged; the dodging element is located between the scattering assembly and the light splitting and combining assembly or located behind the scattering assembly or located between the first scattering element and the second scattering element and used for dodging of light beams entering the dodging element. According to the light source system, the multicolor laser is scattered through the two scattering elements which are independently arranged, the scattering effect is achieved, the size of the light source system is reduced, and light loss is reduced.

AI Technical Summary

Benefits of technology

This patented technology allows for multiple different colored lights from an LED (light emitting device) chip that are mixed together into white light without causing any color distortion during transmission. It also reduces the size of the entire light source by providing more space between neighbored lamps instead of just adding extra components like filters.

Problems solved by technology

The technical problem addressed by this patented solution relates to improving image quality when displaying images through laser displays without causing annoying noises caused by specks or ghost effects that can occur during use. Current methods involve adding an anti-speckling layer before the optical components, such as prismatic layers, to reduce these issues. This approach adds extra costs while also reducing the overall efficiency of the system.
