Abstract

The utility model discloses an illuminating optical system module, including a fluorescent lamp, two glass aspheric surface relay lens, a slice sphere relay lens, a slice planar mirror, a set of RTIR prism and chip subassemblies, each subassembly is fluorescent lamp, first single positive lens, second list positive lens, first speculum, third list positive lens, RTIR prism group, chip subassembly from a left side to the right side in proper order. Through the even photo polymerization of fluorescent lamp, make the inhomogeneous light outgoing uniformly of coming from the light source, make light uniform irradiation to the DMD chip to the refraction effect of light through relay lens's amplification effect and RTIR prism, every declines speculum around the rotation of torsion arm roof beam on the DMD chip again to light reflection to the projecting lens, on the projecting lens projects the screen, have the energy utilization height, advantage that image illumination uniformity is high.

Description

Lamp optical system module

Technical field

The utility model belongs to the video overhead display system technical field of photoelectric display technical field, particularly a kind of lamp optical system module of using on high-end, middle-end digital projector of being adapted to.

Background technology

Along with the development lifting of image information technology, digital technology, network technology and the variation in market, digitized video product technology is stepped into the new stage of upgrading transition, government is also increasing investment aspect voluntary culture and education simultaneously, progressively replace 16 traditional mm film projectors by digital projector, for national public good projection cause. Therefore, for promoting the sustained and rapid development of image industry, universal video image produce market, set up and reflect fast measure for market demand product, this just need to develop the product of modularized design, just extend by changing less parts the kind series products making new advances, realize the object dominating the market fast. As the video overhead display system of photoelectric display technical field---light engine lamp optical system, becomes the key factor of producing high imaging quality video image product, extending fast new product.

Utility model content

The utility model provide a kind of be suitable for high-end, middle-end optics market, capacity usage ratio is high, image quality is superior, and can be compatible 0.7 ", 0.65 ", 0.62 ", 0.55 " etc. different size dmd chip, extend fast the lamp optical system module of other projector's product.

A kind of lamp optical system module, comprise a light pipe, two sheet glass aspheric surface relay lens, a slice sphere relay lens, two plate plane speculums, one group of RTIR prism and chip assembly, described each assembly is followed successively by light pipe, the first single-positive-lens, the second single-positive-lens, the first speculum, the second speculum, the 3rd single-positive-lens, RTIR prism group, chip assembly from left to right, described the first single-positive-lens, the second single-positive-lens are glass aspheric surface relay lens, and described the 3rd single-positive-lens is sphere relay lens.

A kind of lamp optical system module, comprise a light pipe, two sheet glass aspheric surface relay lens, a slice sphere relay lens, a slice plane mirror, one group of RTIR prism and chip assembly, described each assembly is followed successively by light pipe, the first single-positive-lens, the second single-positive-lens, the first speculum, the 3rd single-positive-lens, RTIR prism group, chip assembly from left to right, described the first single-positive-lens, the second single-positive-lens are glass aspheric surface relay lens, and described the 3rd single-positive-lens is sphere relay lens.

By the even light action of light pipe, make the inhomogeneous light outgoing equably of coming from light source, amplification and RTIR prism through relay lens make light uniform irradiation to dmd chip to interception of rays, rotate around turning round arm beam through each micro-reflector on dmd chip again, thereby light reflection to projection lens, through projection lens projects to screen.

The lamp optical system module being designed to according to such scheme, adopt telecentric beam path (angle of chief ray and optical axis is less than 1 °) system, good imaging quality, capacity usage ratio is high, good uniformity, simple in structure, can change light pipe size according to different die size and extend different types of product. Compared with prior art, this light engine scheme not only has high imaging quality, high-energy utilization rate and high technical requirement uniformly, and only change the technical requirement of the light pipe size different size chips such as ", 0.55 " that just can adapt to 0.7 ", 0.65 ", 0.62, thereby design becomes a kind of be applicable to high, middle-end lamp optical system module, not only reduce product development cost, can also greatly shorten product development cycle, thereby can extend fast dissimilar height according to the market demand, middle-end projector product dominates the market.
