Problems solved by technology

[0007] However, for the above-mentioned light source structure, since the rotation of the multi-segment fluorescent pink wheel or the double-segment fluorescent pink wheel must be precisely set in advance to be synchronized with the field color sequential LCOS or DLP or LCD panel, and the color control segment is at The multi-segment fluorescent pink wheel or double-segment fluorescent pink wheel is fixed when it is finished and cannot freely adjust the time ratio of different lights, so a more complicated control system is required

Abstract

The invention relates to a laser projection optical light source framework, and the architecture comprises a laser light source group, a color control device, a fluorescent powder device and an optical filter group; therefore, the laser projection optical light source framework does not need to consider the problem of synchronous rotation of the fluorescent powder device and the field color sequential LCOS or DLP or LCD panel, color control does not need to be set in advance, and different red, blue and green sections can be obtained by adjusting the position of the color control device. And the red, blue and green sections are adjusted through electronic synchronous setting to achieve the purpose of freely controlling colors, so that the problem that the multi-section color wheel cannot directly use the electronic adjustment section to freely control the colors is solved, and a relatively complex synchronous control system is not needed.

Description

【Technical field】 [0001] The invention relates to a laser projection optical light source structure, in particular to a light source structure in which a phosphor device does not need to be synchronized with a panel. 【Background technique】 [0002] The traditional single-chip LCOS optical machine technology can be divided into two types due to the different system panel technologies in the use of light sources: color filter type (Color Filter) and field color sequential type (Field Color Sequential), the latter of which Light use efficiency is higher. [0003] The light source technology in the field color sequence can be divided into two types: with color wheel (color wheel) and without color wheel, and the type of color wheel can be divided into two types: filter color wheel and fluorescent pink wheel. Among them, the light source module using the filter color wheel is usually a white light or a color mixed light source, and the multi-segment multi-color filter in the fil...
