Abstract
The invention discloses a kind of projection, projection technology and device thereof with the function of adding lustre to.It has used 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.This device is closed with the lens imaging principle by the mode of adding lustre to through special non-anti-object lens again, thereby image is absolutely faxed by composition diagram pictures such as light source, non-anti-object lens, prism, lens, screens.
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, projection technology and a device thereof.
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 the disposable light method of using, 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, projection technology and device thereof of adding lustre to, to improve projection, the color rendition degree of projection, lumen degree, sharpness, this technique device not only picture element is good, and cost is suitable.
The present invention is made up of light source, non-anti-object 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 non-anti-object 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.

Colour TV projection arrangement index path (four)
Light enhancer (4) and image-forming objective lens (2) are on same optical axis, it is vertical with image source (5) optical axis, non-anti-object lens (1) be centered close to above two optical axes crosspoint places, Light enhancer (4) and image-forming objective lens (2) are positioned at the both sides of non-anti-object lens (1).
Non-transmission projection device index path (five)
Light enhancer (4) and image-forming objective lens (2) are on same optical axis, the intersection point place that is centered close to above two optical axises of its vertical non-anti-object lens of optical axis with image source (5) (1), Light enhancer (4) and image-forming objective lens (2) are positioned at the both sides of non-anti-object lens (1), and the optical axis of the optical axis of key light device and image source (5) is angled.
Transmission projection device index path (six)
Light enhancer (4) and image-forming objective lens (2) are on same optical axis, and also on same optical axis, two optical axises are orthogonal for key light device (3) and image source (5), and non-anti-object lens (1) are positioned at two optical axes crosspoint places.
Figure (seven) is a kind of example of comprehensive preceding each figure.
Claims (3)
1, a kind of formula projection, projection technology and device thereof of adding lustre to is characterized in that being made up of non-anti-object lens (1), image-forming objective lens (2), key light device (3), Light enhancer (4) image source (5).
