It is not only easy to lift brightness, and is especially suitable for high-end engineering scialyscope product so as to which comprehensive cost performance is far above conventional bulb
Light source.Laser projection major part adds the technology of fluorescent material, the mode for obtaining the light of other colors using blue laser
To color light source.
At present adopting reflection mode or transmission mode Projection Design fluorescent wheel more, due to fluorescent material thickness it is thicker, apart from table
Face fluorescent material farther out is not typically all excited completely, so as to have lost fractional conversion energy.
For reflective fluorescent wheel is designed, blue laser injects excitated fluorescent powder from left side, and dichroic filter piece can be with
Reflection blue light, through gold-tinted, the gold-tinted for ejecting is transmitted away, and the fluorescent material launching efficiency of side on the upper side is relatively low；For transmission
The fluorescent wheel design of formula, blue laser inject excitated fluorescent powder from top, and dichroic filter piece passes through gold-tinted, ejects
Gold-tinted is transmitted away, and the fluorescent material launching efficiency of partial below is relatively low.
Therefore be badly in need of one kind and can increase fluorescent material efficiency, produce the two-way fluorescence excitation structure of more gold-tinted energy.
The content of the invention
In view of problem above, the present invention provides one kind and can increase fluorescent material efficiency, produces the two-way glimmering of more gold-tinted energy
Light excitation structure and its light path implementation method.
In order to realize foregoing invention purpose, the present invention provides technical scheme below：A kind of two-way fluorescence in the present invention swashs
Structure is sent out, the two-way fluorescence excitation structure includes reflective structure blue laser lamp, transmission-type structure blue laser lamp, fluorescence
Wheel, dichroic filter piece, the transmission-type structure blue laser lamp are in the surface of dichroic filter piece, described reflective
Structure blue laser lamp in the left side of dichroic filter piece, the fluorescent wheel be located at transmission-type structure blue laser lamp and two to
Between color filter glass.
Convex lens group is additionally provided between the reflective structure blue laser lamp and dichroic filter piece.
The reflective structure blue laser lamp and transmission-type structure blue laser lamp are screwed in excitation structure
Outside.
The reflective structure blue laser lamp and transmission-type structure blue laser lamp are formed by 1～8Bank combination of light sources.
The fluorescent wheel is fixed on support by metal fixed seat.
A kind of light path implementation method of two-way fluorescence excitation, the blueness sent by the blue laser lamp in transmission-type structure swash
Light injects fluorescent wheel, excites the most of fluorescent material in top to produce gold-tinted, the gold-tinted Jing dichroic filters piece transmission for ejecting
Go out, the blue laser sent by the blue laser lamp in reflective structure injects fluorescent wheel, excite the most of fluorescent material in lower section
Gold-tinted is produced, the gold-tinted Jing dichroic filter pieces for ejecting are transmitted away, realization is simultaneously bi-directionally excited from fluorescent wheel two sides
Fluorescent material.Both are combined, from fluorescent wheel two sides, effectively excitated fluorescent powder produces gold-tinted to blue laser simultaneously, utilizes fluorescent material
Efficiency is maximized.
The advantages of the present invention are to provide one kind to increase fluorescent material efficiency, produce more gold-tinted energy
Two-way fluorescence excitation structure and its light path implementation method.
