Problems solved by technology

[0004] With the increasing use of computer-generated full-color photographic slides and liquid crystal display projection panels, the need to increase the height of projection systems, recent approaches to increasing brightness have focused on the use of more powerful tungsten-halogen lamps and the use of metal halide Lamp technology and high-efficiency anti-reflective reflective coatings on optical components, lamps with higher power tungsten-halogen filaments increase the difficulty of cooling, and arc discharge lamps such as metal halide lamps are more costly, To this end, we propose a multi-light source projector

Abstract

The invention discloses a multi-light-source projector. The multi-light-source projector comprises a shell, wherein one side of the shell is respectively provided with an infrared receiver, a projection lens and a ventilating hole; a cooling fan is arranged inside the ventilating hole; a mounting support and a locker are respectively arranged on the other side of the shell; a slot is formed in the mounting support and corresponds to a latch of the locker; an LED driver and a laser driver are respectively arranged on the mounting support; a red LED light source, a green LED light source and a blue LED light source are respectively arranged on the LED driver; and a laser lamp is arranged on the laser driver. The multi-light-source projector is provided with the red LED light source, the green LED light source, the blue LED light source and the laser lamp, the laser lamp is the main light source, colors of the laser lamp are supplemented by the three-color light sources, projection brightness is improved, and meanwhile, projection colors are saturated and full. The light sources of the multi-light-source projector are arranged on the mounting support, and are matched with one another through the locker and the slot of the mounting support, and therefore, the purpose of quickly mounting and dismounting the light sources is achieved.

Description

technical field [0001] The invention relates to the technical field of projectors, in particular to a multi-light source projector. Background technique [0002] Projectors Under the background of the country's policy of stimulating domestic demand and the continuous improvement of people's income, the implementation of the rural cultural sharing project has further promoted the rapid growth of China's projector market. According to statistics, in 2010 China's projector market shipments reached 1.28 million units, an increase of 43.6% compared to 2009. According to the analysis, China's projector market will continue to grow rapidly in 2011, with annual shipments reaching 1.67 million units and an annual growth rate of about 30%. In the next five years, the compound growth rate of China's projector market will reach 17.1%. [0003] China's projector product consumption market is mainly concentrated in large and medium-sized cities such as North China, East China, and South...
