Light source.Laser projection function realizes the color space for being far longer than conventional light source, and color saturation reaches ultimate attainment, the throwing of LASER Light Source
Shadow machine causes its image quality exported to keep high brightness, saturation degree and contrast, picture color for a long time due to the low attenuation characteristic of light source
It is color as bright as new all the time.
Laser projection is different to brightness demand due to different clients, can use different designs, and between scheme
Widely different, little or no part that can be general will often be redesigned for brightness degree difference is big, resulting
It is costly.
Therefore be badly in need of a kind of quantity that laser module can be freely converted according to customer demand and position and use combined optical system
Holosymmetric light source modular structure.

New offer following technical scheme：
The utility model provides a kind of holosymmetric light source modular structure, including blue laser lamp, fluorescent wheel, convex lens,
Dichroic filter piece, optical channel and closing light structure, the closing light structure include reflective mirror and reflective prism, and the convex lens lead to
Four corners that metal eyeglass folder is fixed on light source modular structure are crossed, the dichroic filter piece is fixed on by metal clips
On the metallic support of light source module structural metal shell, the blue laser lamp, convex lens and dichroic filter piece are equipped with
Four, the both sides of light source modular structure are symmetrically distributed in two-by-two, and fluorescent wheel and reflective mirror are equipped with two, are symmetrically distributed in light source
The both sides of modular structure.Convex lens, which extend light, to converge.Dichroic filter piece can pass through gold-tinted, reflect blue light, gold-tinted
White light is synthesized here with blue light.
The blue laser lamp is screwed.Blue laser is converged on fluorescent wheel, is inspired gold-tinted and is reflected back again
Go.
The fluorescent wheel is fixed on support by metal fixed seat.
The optical channel is located at one end of light source modular structure, relative with fluorescent wheel.Optical channel can import light into back segment system
System.
The reflective mirror is clamping fixed by metal eyeglass.The reflective prism is by metal holder in metal clips mode
It is fixed on metallic support, the metallic support is located at light source module structural metal enclosure in reflective prism and reflective mirror table
Face can be with reflected white-light.
Advantage and beneficial effect of the present utility model are：Laser die can freely be converted according to customer demand by providing one kind
The quantity of block and position and the holosymmetric light source modular structure using combined optical system.One set of die can be shared, is divided into symmetrical
Two parts, save cost.
