Description
Technical field
The present invention relates to projection light source, especially a kind of connection method that projection light source is adapted to projector optical wand.The party
Method is incident in the optical wand of projector with making the beam orthogonal for showing light source sending.
Background technique
When a set of projection light source is adapted to different projectors, if light source position space is very big, can arbitrarily it put
It gives out light source, it is not scabrous for showing the alignment of the optical wand of light source and projector.But the case where frequently encountering, is, places light source
Space it is limited, projection light source can only be placed on a certain specific position, this position projection light source output light beam can not be straight
It connects and vertically inputs in the optical wand of the projector.
The optical wand of projector is a kind of strip cube, and end face is rectangle, and the light beam for showing light source output is rounded, such as
What is normally incident in the rectangle end face of the optical wand of projector, and have the method for solving this problem usually has three below
Kind:
1, using optical fiber as medium, the light beam of light source output is inputted to the optical wand of the projector through optical fiber, by optical fiber
Flexibility, realize the matching of dislocation, usual pure laser light source etendue is smaller, can get in optical fiber, fluorescent powder light
Source and LED light source etendue are larger, and spot size is larger, and optical fiber internal diameter is too small, and light is not achieved in optical fiber, makes by force
With optical fiber, it will cause optical fibre damage, light efficiency is low the problems such as.
2, be different projectors, design different light source matchings, this method, need to be adapted to more than mill model comparison when
It waits, it is time-consuming laborious, it is not a good method.
3, the same light source designs different shots matchs, and reservation light source body is constant, designs for different types different
Light source camera lens can give a little spatial margins if difference is smaller between type, design camera lens adaptation multiple light sources.This
It is not the method to get twice the result with half the effort.
Summary of the invention
