Description
Technical field
The present invention relates to a kind of projector's light structures, and in particular to a kind of projector's optical fiber light structures.
Background technology
At present, the light structures of projector and projection structure design for integral type, and technical sophistication degree is high, product access
Threshold is high, and the volume and weight of product is larger, victory inconvenient for use, and the progress that product enters market is slow.
The content of the invention
Goal of the invention：The invention aims to overcome deficiency of the prior art, there is provided a kind of light structures with into
Picture structure independently separates, plug and play, the optical fiber connection framework of the split type projector of parallel light path easy to use.
Technical scheme：In order to solve the above-mentioned technical problem, the optical fiber of the split type projector of parallel light path of the present invention
Framework is connected, it includes light source input interface and light source output interface, and the light source input interface and light source output interface pass through
Optical fiber is connected, and the optical fiber is fixedly connected by lock screw with light source input interface and light source output interface, in the light source
Input convex lens is provided with input interface, output end convex lens is provided with the light source output interface, the input convex lens leads to
Cross input port fixture to be fixed in light source input interface, the output end convex lens is fixed by output end port fixture
In light source output interface, input glass mirror is provided with the outside of the input convex lens, is set on the outside of the output end convex lens
There is output end glass mirror.
The input glass mirror is located at outside light source input interface.
The output end glass mirror is located at light source output interface internal.
Relay lens and DMD are sequentially provided with outside the light source output interface.
The present invention using the principle of fiber optic conduction illuminator is introduced according to the total reflection principle of light.According to light
Refraction principle, light enter optically thinner medium from optically denser medium, can be totally reflected in critical surface.Optically denser medium refractive index n2, light are dredged
Medium refractive index n1.Critical angle I.
SinI.=n1/n2.Using this principle, after illuminating bundle is collimated, illumination system of projector is transferred to through photoconductive tube
Unite entrance, it is incident after refocusing.Photoconductive tube can be as needed length make, by projector system split into two independent lists
Member is set up, and realizes the flexible connection of two modules.The complexity of the integrated projector of technology height is decomposed, becomes two solely
The design and producing of formwork erection block, technical sophistication degree reduce, reduce the threshold of product access, greatly speed up product and enter market
Progress.Meanwhile product is reduced using module volume and weight, the convenience used is also increased, it is easier to for consumer institute
Receive.
Illuminating system of projector and projection imaging system are separated, are projector using the illuminator of instant inserted and instant using type
Miniaturization, miniaturization create condition.By optical fiber by the energy conduction of light source to optical projection system, used to same projector more
Kind illuminator provides possibility.User can select bulb, LED light source or laser according to hobby, economic condition and quality requirements
Illuminator of the light source as projector.The diversity and facility of light source, facility that projector uses and demand will be brought
Expand.Development to whole projection industry will play great promotion and impetus.The illuminating ray imported by optical fiber, lead to
Outlet export is crossed, and DMD is introduced by the relay lens of projector.Parallel light path spstem is by the emergent light illuminator
Pupil（The entrance pupil of projecting lens）It is arranged on（Or close to）Infinite point.Enter DMD each visual field master by relay lens
Light ray parallel is incided in micromirror.The light that slave introduces in vitro is realized to illuminate optical projection system.
Beneficial effect：Compared with prior art, its remarkable advantage is the present invention：The present invention is connected by optical fiber, according to light
Refraction principle, light enters optically thinner medium from optically denser medium, can be totally reflected in critical surface, individually divided with projection imaging structure
Open, plug and play, projector system split realizes the flexible connection of two modules, make technology height into two independent units
The complexity of integrated projector is decomposed, and technical sophistication degree reduces, and reduces the threshold of product access, greatly speeds up product
Into the progress in market, module volume and weight reduces, and also increases the convenience used.
