Abstract
The present invention discloses a projection and screening technique with an intensifying function, and a device for the technique. In the present invention, a plurality of times of intensifying methods, namely one time of the main light source (or image source) and a plurality of times of auxiliary optical amplification, are used; by the intensifying mode of an electric light source, optical effect is improved. The device forms an image by using a light source, a non-transmission and non-reflection objective lens, a prism, a lens, a screen, etc., and entirely faxes the image through the special non-transmission and non-reflection objective lens by the intensifying mode and the lens imaging principle.
Description
The present invention relates to the optical, mechanical and electronic integration device of a kind of film, TV, nontransparent projection in kind and projection, particularly a kind of have the function of adding lustre to projection, a projecting device.
Existing transmission, reflection type projection, projection equipment, its projection, projection technology are varied, but its ultimate principle is of an identical nature, and light source all adopts disposable smooth method, and this thinking has had a strong impact on the development of projection, projection technology.Such as the projection of single mirror direct putting type, projection principle, although it has better solved the defective that three mirror pipes are thrown formula three-color light source crevice projection angle error, color rendition difference, brightness is dark partially, lumen is low excessively, and visuality is relatively poor.And for example three mirror pipes are thrown formula projection, projection principle, although brightness, lumen are higher than single mirror direct putting type, and complex process, and picture element is relatively poor, cost is quite high, has greatly influenced popularizing of product.
The object of the present invention is to provide a kind of formula projection, projecting device of adding lustre to, to improve projection, the color rendition degree of projection, lumen degree, sharpness, this installs, and not only picture element is good, and cost is suitable.
The present invention is made up of light source, semi-transparent semi-reflecting lens, prism, lens, screen and electrical structure spare etc.Its core technology is the method for adding lustre to for several times, i.e. for several times auxilliary light amplification of a main light source (or image source) improves light efficiency in the electric light source mode of adding lustre to, and its critical component is to close with the lens imaging principle through special semi-transparent semi-reflecting lens again, thereby image is absolutely faxed.
This technology is widely used, be used for cinematographic equipment and can show adhesive tape, can show nontransparent paper tape again, the 35mm film copy can be shown, the 70mm film copy can be shown again, can show light playback film, can show magnetic playback film again, being used for projector equipment is projectable's transparent film, the nontransparent picture in kind of projectable is used for television projection not only projectable's colour TV picture but also projectable's black-and-white television image again.
Below in conjunction with accompanying drawing six embodiment are described.

The color projection device light path, figure (four),
Secondary light source (4) and image-forming objective lens (2) are on same optical axis, and it is vertical with image source (5) optical axis, semi-transparent semi-reflecting lens (1) be centered close to above two optical axes crosspoint places.Secondary light source (4) and image-forming objective lens (2) are positioned at the both sides of semi-transparent semi-reflecting lens (1).
Non-transmission projection device light path, figure (five),
Secondary light source (4) and image-forming objective lens (2) on same optical axis, itself and the intersection point place that is centered close to above two optical axises of the vertical semi-transparent semi-reflecting lens of image source (5) optical axis (1).Secondary light source (4) and image-forming objective lens (2) are positioned at the both sides of semi-transparent semi-reflecting lens (1), and the optical axis of the optical axis of main light source and image source (5) is angled.
Transmission projection device light path, figure (six), secondary light source (4) and image-forming objective lens (2) are on same optical axis, and also on same optical axis, two optical axises are orthogonal for main light source (3) and image source (5), and semi-transparent semi-reflecting lens (1) is positioned at two optical axes crosspoint places.
Figure (seven) is a kind of example of comprehensive each figure of front.
