Description
Affiliated technical field
The present invention relates to a kind of externally-connected light path of projector optical fiber, the externally-connected light path of projector optical fiber of external light source especially can be provided for micro projector.
Background technology
Micro projector is brought into use the LED miniature for reduced volume at present, but be subjected to the light-source brightness restriction, cause projection brightness, lumen very little, if use a plurality of led light source arrays, projector volume, lens design complexity have been increased, special-purpose projector brightness requirement is very high, so the micro projector of led light source does not reach the light-source brightness requirement, has limited to purposes.
Summary of the invention
In order to overcome the little deficiency that waits of existing micro projector light-source brightness, the invention provides a kind of externally-connected light path of projector optical fiber, this projector design can be used 1～N miniature built-in light source, can the external light source of external high brightness when needing, and make micro projector brightness satisfy professional requirement.
The technical solution adopted for the present invention to solve the technical problems is: design the external light source converting interface on the road of sharing the same light outside the built-in light source on micro projector, can connect external light source.At LED miniature built-in light source (1) peripheral hardware focusing light cone (2) or with LED miniature exterior design is the miniature focused light source of LED, connect fibre-optic bundle (3), wherein a fibre-optic bundle is provided with external light source converting interface (7), all fibre-optic bundle single fiber lack of alignment are aggregated into a branch of.Light is evenly projected on prism (4) and the liquid crystal wafer (5).
The invention has the beneficial effects as follows, use the present invention and can use built-in led light source simultaneously, satisfy and move portable needs, can external external higher source luminance when specialty needs, micro projector brightness is satisfied the demand.Light source is put the installation site freedom, and overall volume is little, the optical texture simplicity of design, and cost is low.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural map of externally-connected light path of projector optical fiber.
Fig. 1 is the structural map of the 2nd embodiment of externally-connected light path of projector optical fiber.
(1) miniature built-in light source among the figure, (2) focus on light cone, (3) fibre-optic bundle, (4) prism, (5) liquid crystal wafer, (6) converting interface focuses on light cone, (7) external light source converting interface.
Embodiment
In Fig. 1, on micro projector, outside the built-in light source, the external light source converting interface with light path is arranged, connect external light source.Built-in LED miniature built-in light source (1) outer design focused light awl (2) or be focused light source with LED miniature exterior design, light source focus place connects fibre-optic bundle respectively, fibre-optic bundle (3) has branch, wherein a fibre-optic bundle connects converting interface focusing light cone (6) and external light source converting interface (7), all fibre-optic bundle irregular alignments are aggregated into a branch of, terminal throwing is identical with prism (4) or liquid crystal wafer (5) according to the cross section, and light is evenly projected on projector prism (4) and the liquid crystal wafer (5).
In Fig. 2, the light of built-in LED miniature built-in light source (1) and external light source converting interface (7) directly is projected on projector prism (4) and the liquid crystal wafer (5) by optical system.
