Abstract
The invention discloses a dustproof, noise-reduction and heat-dissipation device of a laser television. The dustproof, noise-reduction and heat-dissipation device of the laser television is provided with a heat-dissipation structure matched with an optical engine, wherein the optical engine is a laser optical engine; a red semiconductor laser, a green semiconductor laser and a blue semiconductor laser are adopted as light sources of the optical engine; the heat-dissipation structure is composed of heat-dissipation fans and an air duct; the air duct has two air inlets and four air outlets, wherein the four air outlets respectively are a red light air outlet, a blue light air outlet, a green light air outlet and a polarizer air outlet, and the air inlets are provided with dust-proof nets; and the heat-dissipation fans are arranged in the air duct at a lower portion of the optical engine. With the dustproof, noise-reduction and heat-dissipation device of the laser television adopted, a large quantity of heat can be taken away, and heat dissipation ability can be improved, and dust entering the laser television can be reduced, and noise of a whole machine can be reduced.
Description
Technical field
The invention belongs to laser television technology field, be specifically related to a kind of laser television dust control and noise absorption heat abstractor.
Background technology
In the large screen televisions such as rear-projection TV, plasm TV, panel TV, all have a common problem at present, that is exactly dust control and noise absorption and the heat dissipation problem of TV.Light path system is the key that ensures complete machine picture quality, and its reasonability has determined that whether complete machine structure reasonable, determined whether complete machine can use for a long time and light path can be not contaminated, picture quality can not decline.Dust has very serious impact to laser television, because dust not only can have influence on the radiating effect of laser television, if once the camera lens of laser television simultaneously has dust accumulation around, will affect the quality of laser television picture, serious words also can have influence on the useful life of laser television light source.High temperature is the killer of electronic devices and components, and too high temperature can cause system unstable, accelerates the aging of electronic devices and components and optics, affects the useful life of laser television.
Summary of the invention
The object of the invention is to solve laser television dust control and noise absorption and heat dissipation problem in use, reduce the impact of dust on laser television internal electronic component, reduce the noise of complete machine, build good ventilating system, avoid Yin Gaowen and cause the aging of internal electronic component, thereby increase the service life.
For achieving the above object, the technical solution used in the present invention is: this laser television dust control and noise absorption heat abstractor, there is the radiator structure coordinating with the light engine that is positioned at casing, it is characterized in that: described light engine is laser optical engine, by red laser diode, green semiconductor laser and blue semiconductor laser are as the light source of light engine, described redness, laser green and blue semiconductor laser transmitting passes through respectively beam treatment module, polarization beam apparatus, LCOS chip imports color-combination prism, through the synthetic laser beam that comprises all image informations of color-combination prism, by projection lens, through speculum, image is projected on video screen, described radiator structure consists of radiator fan and air channel, described air channel has two air intake vent air channels and four air outlets, four air outlets are respectively ruddiness air outlet, blue light air outlet, green glow air outlet, polarizer air outlet, described air intake vent adds Air Filter, and the air channel that is positioned at laser optical engine bottom is provided with radiator fan.
Adopt the beneficial effect of technique scheme to be: this laser television has casing, video screen, is positioned at the light engine of casing, speculum, Core of TV set the electric circuit constitute.The heat that laser television produces mainly concentrates on light engine and internal circuit, and light engine consists of the Lights section and light path system.The special air duct building, forms from convection current the cold and hot circulation of air of laser television inside, can take away most of heat, makes the air of laser television inside can keep circulation, improves heat-sinking capability.By installing the Air Filter of disassembling cleaning additional, not only reduced the dust that enters laser television inside, and made the airtight space of the inner formation of laser television, reduced dust and enter laser television inside by radiator window, affect light path system and internal circuitry, also reduced the noise of complete machine.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, specific embodiments of the invention are described in further detail.
Fig. 1 is laser television structural representation.
Fig. 2 is laser optical engine light path system schematic diagram.
Fig. 3 is light engine air channel structure schematic diagram.
