The invention provides a projecting device, a light source system for displaying and control methods thereof. The light source system for displaying comprises a light source module and a control module. The light source module comprises a plurality of laser light sources; and the control module controls a plurality of the laser light sources to be at an opening / closing state according to a light power needed by displaying, so as to enable an actual output power of the light source module to be equal to the light power needed by displaying. With the adoption of the manner, the laser light source which is at the opening state can be ensured to work under the state that the output efficiency is relatively higher, and the optimization of the output efficiency can be realized.
Description
technical field [0001] The invention relates to the field of optical technology, in particular to a projection device, a display light source system and a control method thereof. Background technique [0002] At present, laser light sources are widely used in various display fields, for example, as an excitation light source of a projection device to excite a color wheel of a fluorescent material to generate a three-primary color light sequence. In practical applications, it is usually necessary to adjust the output optical power of the laser light source to achieve different display requirements. [0003] In the prior art, when adjusting the output optical power of the laser light source, the output optical power is usually adjusted by adjusting the driving current of the laser light source, so as to meet the optical power required by different display requirements. [0004] see figure 1 , figure 1 It is the curve diagram of the output optical power and output efficiency...
