Abstract

The application discloses a projection display light source control system. The system includes: a first laser, used to emit light of a first wavelength, wherein the first wavelength light is blue light or purple light or ultraviolet light; a first wavelength conversion device is used to convert the first wavelength light, wherein the first The light converted by the wavelength conversion device includes light of multiple wavelengths, and the light of multiple wavelengths includes light of the first target wavelength; the second laser is used to emit light of the second wavelength, wherein the light of the second wavelength is used for the first target wavelength. A target wavelength of light is compensated. Through the present application, the problem of poor consistency of optical parameters in laser projection in the related art is solved.

Description

Projection display light source control system technical field [0001] The application relates to the technical field of light source control, in particular, to a projection display light source control system. Background technique There are many types of light source system designs on the market at present, such as LED light source, bulb light source, Laser light source, etc., but these The optical system of the light source should have its own advantages and disadvantages, mainly as follows: The advantages of the LED light source are that the light source is simple to control and has a long life. 20,000 hours, the disadvantages are low brightness and relatively high LED heat dissipation cost; the advantages of light bulb light source are control modularization, optical parameters Stable, the disadvantage is that the brightness is relatively low, and the service life is very short (2000 hours to 3000 hours). The control method is relatively simple. The advantages of ...
