Abstract
The invention discloses a laser projection display device which comprises red, green and blue three-color semiconductor laser light sources, three coupling optical fibers, a light-bundling sleeve, a light-adjusting frame and a DLP (Digital Light Procession) projection component, wherein the three-color semiconductor laser light sources are one-to-one corresponding to the three coupling optical fibers; three-color semiconductor laser lights are outputted through the coupling optical fibers; output ends of the three coupling optical fibers are bundled together by the light-bundling sleeve, thereby forming a combined white laser light; the light-bundling sleeve is mounted on the light-adjusting frame; the light-adjusting frame has two-dimensional angle adjustment and two-dimensional translation adjustment and is mainly used for adjusting an output direction of the combined laser light; the red, green and blue semiconductor laser lights pass through the coupling optical fibers and are combined into the white laser light; and the outputted white laser light passes through a color wheel, an optical component, a DMD (Digital Micromirror Device) and a projection lens in the DLP projection component and is projected and displayed under the control of a control system. The laser projection display device provided by the invention is low in energy consumption, long in service life and high in luminance. By using the laser projection display device, a projected image is clearer and brighter in color.
Description
Technical field
The present invention relates to a kind of laser projection display apparatus, relate in particular to the small-sized projector equipment of low-power consumption high brightness, belong to shadow casting technique's application.
Background technology
Commercial at present and home-use most of projector mainly adopts the white light source of light fixtures such as metal halid lamp or ultrahigh pressure mercury lamp as Projection Display; Projection bulb is the of paramount importance consumptive material of projector, and its performance quality is directly determining the sharpness and the brightness of projected image.Along with the prolongation of projection working time, the brightness of bulb can constantly reduce naturally, thereby influence the image projected sharpness, so bulb life and higher maintenance cost of later stage become the problem that highlights that has projector now; In addition, in order to obtain the display effect of high brightness, often to improve the lumen degree of light fixture; For projection light source, the luminous flux how many luxs its every watt electric weight can obtain is certain, so its lumen degree is directly proportional with electric power; Brightness (lumen) is high more, and power consumption is big more, and heat dissipation capacity is big more; Exhaust air rate is big more, and noise is big more, is the another problem that highlights that existing projector exists.
Along with the quick and marketing development of red, green, blue semiconductor laser product, laser becomes a kind of trend gradually as the light source of Projection Display.Laser projection shows to be compared with traditional bulb projection display technique: have bigger gamut range; Laser monochromaticity is good, and laser is line spectrum, has high color saturation, make color more truly, more bright-coloured; Laser direction property is good, and the divergence of light beam is little, can improve the sharpness of image; Power consumption is little, and reach up to ten thousand hours serviceable life, thereby becomes the significant development direction in demonstration field.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned many shortcomings that existing projector light source exists, provide that a kind of low energy consumption, high brightness, color are more bright-coloured, the laser projection display apparatus of long service life.
Technical scheme of the present invention is, a kind of laser projection display apparatus is characterized in that, this laser projection display apparatus comprises red, green, blue three look semiconductor laser light resources, three coupled fibers, bundle light sleeve pipe, light adjusting bracket, DLP projecting subassembly; Described red, green, blue three look semiconductor laser light resources are corresponding one by one with three coupled fibers respectively, and red, green, blue three look semiconductor lasers are through coupled fiber output; The output terminal of described three coupled fibers forms an output white light laser that closes bundle by bundle light sleeve pipe big envelope together; Describedly make three coupled fibers close bundle bundle light sleeve pipe together to be installed on the light adjusting bracket; Described smooth adjusting bracket has the two dimension angular adjusting and two-dimension translational is regulated, and is mainly used in to regulate the outbound course that closes Shu Jiguang; Described red, green, blue semiconductor laser is through coupled fiber and close colour wheel, optical module, DMD and the projection lens of white light laser in the DLP projecting subassembly of bundle output, under the control of control system, realizes Projection Display.
The invention has the beneficial effects as follows: a kind of laser projection display apparatus is provided; Overcome many shortcomings such as conventional projector is big as the power consumption that light source exists with bulb, the life-span is short; Thereby influence the problem such as sharpness and brightness of projected image, provide that a kind of low energy consumption, high brightness, color are more bright-coloured, the laser projection display apparatus of longer service life.
