The light source regulating device of optical projection system
Technical field
The present invention relates to a kind of light source regulating device of optical projection system, the light source regulating device of the optical projection system of particularly a kind of adjustable light source position
Background technology
Along with the continuous progress of optics science and technology, optical projection system just is being widely used in the every field at present, for example in meeting, science and technology association, exhibition, all usually presents multimedia presentation content with optical projection system.In order to make the projection image's data that present clear and lively, projection brightness is a very important consideration.Generally, projection brightness is healed when high, and how therefore relative also better of the effect of projection utilize easy method to promote projection light source brightness in the optical projection system, and adjust calibration light source and make it can focus on the optimum position, just become a very important problem.
Generally speaking, digit optical is handled (Digital light Processing, DLP) action principle of optical projection system is for after the light that utilizes the spectroscope group that light source regulating device (being the optical projection system bulb) is provided tells R, G, B primaries, close the light colour mixture again, and then adjust needed optical image, wherein the brightness of light that light source regulating device provides and homogeneity have all been played the part of considerable role at this; Thereby in order to make optical projection system that more perfect projected picture quality can be provided, the adjustment of optical projection system light source regulating device and the optical frames group in the optical projection system are of equal importance.
See also Fig. 1, it has described traditional optical projection system light source regulating device; This light source regulating device 10 comprises a bulb 11, and the front side of this bulb 11 is directly fixed on the framework 13 by screw 12; This bulb 11 also is installed in the optical projection system (not shown) by this framework 13.In such design, the lighting position of bulb 11 can't be adjusted, and therefore, after optical projection system is gone in light source regulating device 10 installings, if its lighting position is desirable not to the utmost, then must install this light source regulating device 10 again.
And in order to promote the illumination efficiency of optical projection system light source regulating device, a kind of continuous color recovery technology of available technology adopting (SCR, Sequential Color Recapture) reaches this technique effect.See also Fig. 2, this technology is in optical projection system 21, dispose a catoptron 24 in the inboard of integration rod 22 inlet ends 23, the reflex by light reclaims light, make light that bulb 25 provided can be only by a micro-pore 26 incidents at these integration rod 22 centers.Such technology can effectively improve the illumination efficiency of optical projection system light source regulating device, and just wherein the focus of bulb 25 must accurately be aimed at the center of integration rod 22, to reduce the illumination loss; And because in traditional optical projection system light source regulating device, can't maneuverability ground adjust the lighting position of bulb, so still there is its where the shoe pinches in this technology when carrying out, if can flexibly adjust the bulb focal position, then can overcome this problem.
See also Fig. 3, it is a kind of exterior case synoptic diagram of optical projection system; This optical projection system device 30 comprises an exterior case 31, uncap 32, one opening 33 and a plurality of control knob 34; Wherein, place every intraware of this optical projection system device 30 in the exterior case 31 of this optical projection system device, and when every intraware all assemble complete after, then utilize this to uncap and 32 this optical projection system device 30 added a cover seal, to finish the equipped work of this optical projection system device 30; According to the design of the optical projection system device 30 of various different type of machines, these 32 front or back sides that can be positioned at the exterior case 31 of this optical projection system device of uncapping; This opening 33 is the opening of emission one light source; Described a plurality of control knob 32 then is in order to controlling every function of this optical projection system device 30, the quantity of wherein said a plurality of control knobs 32 and function then according to various different type of machines optical projection system device 30 and different.Because in the prior art, the adjusting module complex structure of bulb adjusting gear, processing are difficult for, when adding bulb adjustment each time, the exterior case of whole optical projection system all must be disassembled, could be adjusted the focal position of bulb again; The assembling of whole optical projection system device then be need wait until that bulb is reorientated after, could be equipped with the part of exterior case again, treat that assembling finishes after, could calculate the assembly work of finishing this optical projection system device 30.In the whole process, except expending the time of adjusting the bulb position, equipped again exterior case is wasted very many time and manpower especially, also therefore be severely limited on the production run, therefore cost also improves many, therefore improves the adjustment mode of bulb, becomes extremely important.
