Description
The application is the divisional application of the Chinese invention patent application 201310087954.6 of invention entitled " light supply apparatus, light source generation method and the laser projection comprising light supply apparatus " that propose on 03 19th, 2013.
Technical field
The present invention relates to Color Laser Projection Technology, particularly to a kind of light supply apparatus, light source generation method and the laser projection comprising light supply apparatus.
Background technology
In recent years, laser projection is widely used in multiple occasion because of advantages such as its life-span length, picture brightness height and rich colors, such as television projection, micro projection and some commercial, education and home entertainment system etc..
It is known that optical frame at least needs by the light wave component of different dominant wavelengths, such as by blue, green and red light wave component.In current prior art, the light source of another kind of wavelength can be generated under normal circumstances using the light source of a kind of wavelength as exciting light, the most again with the light source time division emission of other wavelength, demonstrate various picture on the projection screen.For example, it is possible to the blue laser sent using blue semiconductor laser is as exciting light, excite green light fluorescent powder to produce green glow.
Fig. 1 is structure and the principle schematic of light supply apparatus in prior art.Seeing Fig. 1, light source here includes: the first light source 101, secondary light source (not shown in figure 1) and the 3rd light source 116 that wavelength is different.This light supply apparatus includes: collimating mirror 102, reflection lens group the 103, first collecting lens the 104, first dichroic sheet the 105, second collecting lens 106, fluorescent wheel the 107, first deviation mirror 109a, the second deviation mirror 109b, the first reflecting mirror 110a, the second reflecting mirror 110b, the second dichroic sheet the 111, the 3rd collecting lens 112, optical wand the 113, the 4th collecting lens 114 and the 3rd deviation mirror 115.
Wherein the first dichroic sheet 105 allows the first light source and the 3rd light source to pass through, reflect secondary light source, and the second dichroic sheet 111 allows the first light source to pass through, and reflects secondary light source and the 3rd light source.
Further, being coated with fluorescent material in the subregion of fluorescent wheel 107, in the case of with the first light source 101 as exciting light, the region being coated with fluorescent material produces secondary light source.Owing to fluorescent wheel is rotatable, the first light source is irradiated to the zones of different of fluorescent wheel 107, can produce the light of different wave length.
In FIG, the light beam with first wave length of the first light source 101 outgoing is that divergent shape is incident to collimating mirror 102, and this beam collimation is become collimated light beam by collimating mirror 102；The reflection of reflection lens group 103 makes the optical axis 90-degree rotation of this collimated light beam, and the collimated light beam after rotating optical axis is assembled, to the first dichroic sheet 105 outgoing by the first collecting lens 104；The light beam of the first light source is through after the first dichroic sheet 105, after the second collecting lens 106 convergence processes, arrives fluorescent wheel 107.
Fluorescent wheel 107 rotates under the driving driving motor 117.For the fluorescent wheel 107 in rotating, if the first light source 101 is incident in phosphor area, excitated fluorescent powder launches the secondary light source with second wave length, this secondary light source is with the direction outgoing in contrast to the first light source incidence direction, after arriving the first dichroic sheet 105, its optical axis is rotated by 90 degrees under reflection, then after the first deviation mirror 109a, the first reflecting mirror 110a, the second deviation mirror 109b, incident to the second dichroic sheet 111；Owing to secondary light source is reflected by the second dichroic sheet 111, then light beam directive the 3rd collecting lens 112 of secondary light source, finally focuses in optical wand 113.During in short, the first light source 101 is incident in the phosphor area of fluorescent wheel 107, what optical wand 113 was collected is the secondary light source with second wave length.
If the first light source 101 is incident in the penetrating region of uncoated fluorescent material on fluorescent wheel 107, first light source 101 transmission fluorescent wheel 107, after the 4th collecting lens the 114, second reflecting mirror 110b and the convergence of the 3rd deviation mirror 115, reflecting and turn to, transmit to the 3rd collecting lens 112 through the second dichroic sheet 111, finally focus in optical wand 113.During it is to say, the first light source 101 is incident in the penetrating region of fluorescent wheel 107, what optical wand 113 was collected is first light source with first wave length.
There is the 3rd light source 116 of the 3rd wavelength to be parallel to the direction outgoing of the optical axis of the first light source, after the convergence of the second collecting lens 106, arrive the first dichroic sheet 105, owing to the first dichroic sheet 105 allows the 3rd light source to pass through, then the 3rd light source is again after the first deviation mirror 109a, the first reflecting mirror 110a, the turning to, reflect and turn again to of the second deviation mirror 109b, and arrives the second dichroic sheet 111；Second dichroic sheet 111 is by the optical axis 90-degree rotation of the 3rd light source 116, through the 3rd collecting lens 112, finally focuses in optical wand 113.
Based on above structure and principle, by controlling the first light source and the lighting time of the 3rd light source, control the rotary speed of fluorescent wheel, it is possible to achieve the first light source, secondary light source, the 3rd light source timesharing enter in optical wand 113 simultaneously, obtain the hot spot of different colours, and then constitute display picture.
Although above-mentioned existing light supply apparatus makes laser projection be achieved, but, the driving motor 117 of the fluorescent wheel 107 from Fig. 1 it is found that in this light supply apparatus is electric rotating machine.Described electric rotating machine, due to the impact of rotary inertia, can make the motor shaft of described electric rotating machine have one periodically to swing around axle.Therefore, when electric rotating machine starts to rotate, the motor shaft of this electric rotating machine produces when swinging, described fluorescent wheel 107 will be made to have the movement before and after relative to predetermined design attitude, so that light source produced by above-mentioned light supply apparatus is also due to move before and after fluorescent wheel 107 and produce periodic brightness flop, thus result in the change of periodicity light and shade and the inhomogeneities of picture brightness of same projected picture, reduce the quality of projected picture.Meanwhile, the system of above-mentioned existing light supply apparatus is the most more complicated, debugs relatively difficult.Additionally, in light supply apparatus in the prior art, the motor of high speed rotating itself is also a potential safety hazard.
From the foregoing, it will be observed that light supply apparatus of the prior art there is also some above-mentioned problems, therefore, it is necessary to provide one can more preferable light supply apparatus, thus avoid light source to produce the problem of periodically brightness flop, the quality of raising projected picture.
