Summary of the invention
The object of the present invention is to provide a kind of environment-friendly and energy-efficient double light source projection type simulation panel, remarkable to reach energy-saving effect, cut operating costs and the purpose of environmental protection; Can adapt to continuous variation of electric system electrical network again and cause the frequent requirement of revising of imitation screen.
Technical scheme of the present invention is: comprise light source cell, be successively set on the light element on the light path, image-display units, the optics amplifying unit, display screen, the regulation and control unit of control and adjusting image effect, it is characterized in that, described light source cell is made of microwave sulfur lamp light source and sunshine condenser two parts, described light element has the light pipe of two branches by a front end and the convex lens of light pipe rear end constitutes, two branches of light pipe are located at respectively on the light path of sunshine condenser and microwave sulfur lamp light source, the convex lens of light pipe rear end projects image-display units with light beam, the drive plate of image-display units is connected with the regulation and control unit, and described regulation and control unit is made up of computer motherboard and control loop.
Described microwave sulfur lamp light source comprises microwave sulfur lamp, and microwave sulfur lamp is connected with cold air duct, and a side of described cold air duct is equipped with exhaust fan, and the offside of exhaust fan has ventilation slot, imports and exports at cold air duct heat-protecting glass is housed, and heat-protecting glass is communicated with a branch of light pipe.
Described sunshine condenser is the combination of a condenser or a plurality of condensers or the combination of organizing condenser more.
Described image-display units is liquid crystal imaging technology or DLP digital projection technique or technique of laser imaging, is prior art.
Described image-display units is by liquid crystal panel, and the preceding Fresnel Lenses in liquid crystal panel the place ahead and the back Fresnel Lenses at liquid crystal panel rear and liquid crystal imaging drive plate are formed.
The model of described Fresnel Lenses and parameter are according to varying in size of liquid crystal panel and different.
When described projection screen size is 50-300; Can be designed to different size and size according to user's requirement.
Described projection screen is the rear-projection curtain or is just throwing curtain.
The present invention adopts microwave sulfur lamp to make light source, and this light source energy-saving effect is remarkable, is equipped with the sunshine condenser again and forms composite light source, daytime is when sunny, sunshine can provide light source separately, replenishes light source by microwave sulfur lamp again when sunlight is not enough, and separately provide light source by microwave sulfur lamp night; So saved the energy greatly, operation costs reduced greatly; The microwave sulfur lamp long service life has solved the problem that traditional projection pattern bulb can not work long hours; Microwave sulfur lamp does not have ultraviolet ray and ultrared pollution, not halogen-containing and mercury, environmentally safe, compliance with environmental protection requirements; The employing computer combines with projection, has eliminated slit and the inharmonic defective of integral color that screen test brings because of splicing; Eliminated brick pattern piece screen wiring complexity, defective difficult in maintenance, remedied the bus-structure type simulation screen system and revised untimely deficiency, can adapt to that electrical network constantly changes and the frequent requirement of revising of imitation screen that causes.
