Illuminating device

一种发光装置

Abstract

The utility model discloses an illuminating device, include: the light source for form the incident beam, beam splitting device, be used for with the incident beam beam splitting is first light beam and second light beam, a collection device, be used for with first focusing of beam is to a wavelength converters, a wavelength converters for absorb the blue laser in the first light beam and excited the first laser that receives of transmission, the first not absorbed first light beam of light sum of being excited returns through a collection device collimation beam splitting device to form first emergent light, the 2nd collection device, be used for with the second focusing of beam is to the optical processing device, the optical processing device, it is right to be used for the second light beam carries out optical processing, light beam behind the optical processing returns beam splitting device through the 2nd collection device collimation to form the second emergent light. The utility model discloses the intensity and the colour that can make the emergent light are more even to reduce the loss of spectrum, improve laser lamp -house's efficiency.
本实用新型公开了一种发光装置,包括:光源,用于形成入射光束;分光装置,用于将所述入射光束分束为第一光束和第二光束;第一收集装置,用于将所述第一光束聚焦到第一波长转换装置;第一波长转换装置,用于吸收第一光束中的蓝色激光并受激发发射第一受激光,所述第一受激光和未被吸收的第一光束,经第一收集装置准直返回到所述分光装置,以形成第一出射光;第二收集装置,用于将所述第二光束聚焦到光学处理装置;光学处理装置,用于对所述第二光束进行光学处理;光学处理后的光束经第二收集装置准直返回到分光装置,以形成第二出射光。本实用新型能够使出射光的强度和颜色更加均匀,并减少光谱的损失,提高激光光源的效率。
