White laser light source

Abstract

The invention discloses a white laser light source which comprises a laser emitting unit, a laser scattering unit, a white light combining unit and a white light emitting unit, wherein the white light combining unit comprises a dichroscope, a blue light excitation module and a yellow light excitation module, and the laser scattering unit and the yellow light excitation module are located on the same side of the dichroscope. The white light emitting unit and the blue light excitation module are positioned on the same other side of the dichroscope; the blue light excitation module comprises a blue light lens and a blue light ceramic chip which are sequentially arranged in the laser beam propagation direction, and the yellow light excitation module comprises a yellow light lens and a fluorescent wheel which are sequentially arranged in the laser beam propagation direction. The mode that the yellow light lens and the fluorescent wheel are arranged in the yellow light excitation module is adopted, namely, the fluorescent wheel is adopted as a yellow light excitation component, the saturation phenomenon of a fluorescent piece is solved, the technical purpose of a high-power light source is achieved, meanwhile, the focusing effect of the yellow light lens is combined with the fluorescent wheel, and the optical density is improved.

Description

technical field [0001] The invention relates to the technical field of fluorescent lasers, in particular to a white light laser light source. Background technique [0002] Existing visible light laser lighting sources can be divided into blue light excitation phosphor to realize white light lighting and red, green and blue laser synthesis white laser or true color light lighting according to different principles. Laser lighting can greatly increase the throw distance, while being smaller and more compact. However, although the existing laser lighting sources have better performance than LEDs, the traditional fluorescent sheets used in them have saturation phenomenon, and the irradiation power has an upper limit, which can only realize low-power light source design. Therefore, it is urgent It is necessary to provide a light source that solves the light saturation and thermal saturation phenomena of the fluorescent sheet, so as to promote the development of fluorescent laser ...
