Reflection type laser illumination system

Abstract

The invention discloses a reflection type laser illumination system which comprises a light source, a beam splitter, a base plate, a wavelength conversion layer and a reflection film layer, wherein the base plate, the reflection film layer and the wavelength conversion layer are sequentially compounded; the beam splitter is arranged between the light source and the wavelength conversion layer; after light beams emitted from the light source are emitted onto the beam splitter, reflection light beams and wavelength conversion reflection light beams converted after the light beams pass through the beam splitter and are emitted onto the wavelength conversion layer are obtained; the reflection light beams and the wavelength conversion reflection light beams are merged in a light beam merging point; and mixed light is obtained. The functions of wavelength conversion, light reflection, light mixing, light homogenizing and the like are realized; the light efficiency is high; the irradiation distance can reach more than 10 km; and the laser illumination service life is long, is more than 5 times that of an existing mainstream illumination LED, and is more than 10 times that of a xenon lamp.

[0003] A current laser lighting system, such as a laser lighting spectroscopic device disclosed in Chinese Patent Application No. 2012203086829, includes a convex lens, a light source emitter, a lens frame and a base plate, and the convex lens is installed on a far-end cover, and the far-end cover It is connected with the light source emitter through two fixed guide rods fixed on the lens frame, the distal end cover is installed on the bottom plate by screws, and a double layer is installed on the lens frame. Gaussian uniform light film, an obvious defect in this patent is that it is difficult to apply high-power lighting, low light efficiency, light beams are greatly affected by installation accuracy, high cost, and difficult to apply in large quantities; another example is the adoption of Chinese patent application No. 2011204387369 Laser lighting device for optical fiber shaping and homogenization, including a laser with a cylindrical mirror and an optical fiber section as a homogenizer; a device is provided between the cylindrical mirror and the optical fiber section for coupling the laser beam shaped by the cylindrical mirror into the optical fiber Short-focus focusing lens in the segment; it is difficult to apply high-power lighting, high installation requirements, and very low production efficiency

[0004] To sum up, the obvious defects of the current laser lighting devices and designs are that it is difficult to apply high-power lighting, low light efficiency, high installation and positioning requirements, very high precision processing of structural parts, high cost, and low production efficiency.
