Embodiment
In order to make explanation clearer, be easier to understand below in conjunction with accompanying drawing, scheme of the present utility model is elaborated.
In conjunction with Fig. 1, the utility model proposes the first embodiment.A kind of laser facula correction system, comprising: laser array and Light modulating device 2, wherein, laser array comprises at least two lasers 1 and Light modulating device 2.
(1) laser 1, for generation of laser, forms irradiating light beam.
Wherein, the number of laser 1 arranges as required, can arrange any number of.Each laser 1 all comprises a laser chip 11 and a collimating lens 12, laser chip 11 Emission Lasers, and this laser, after collimating lens 12 collimations, forms irradiating light beam.
(2) Light modulating device 2 is positioned at the outgoing beam direction of laser, wherein, a Light modulating device 2 is all set in the outgoing beam direction of each laser.Adjust the direction of irradiating light beam by mobile Light modulating device 2, form and correct light beam.Light modulating device 2 can adjust the direction of irradiating light beam automatically also can be by manually adjusting the direction of irradiating light beam.
Wherein, Light modulating device 2 can be the element of the direction of the outgoing beam that can be used for arbitrarily regulating laser, for example: speculum, convex lens, concavees lens, in the time that Light modulating device 2 is speculum, the outgoing beam of part laser, after speculum regulates, does not change the cross-sectional area of outgoing beam; In the time that regulating element 2 is concavees lens, the outgoing beam of laser is after concavees lens regulate, and it is large that the cross-sectional area of outgoing beam becomes; In the time that Light modulating device 2 is convex lens, the outgoing beam of laser is after convex lens regulate, and the cross-sectional area of outgoing beam changes.In the present embodiment, preferred, Light modulating device 2 is convex lens, and this technical scheme can make to correct light beam and propagate along predefined paths, the receipts light of being more convenient for follow-up.And this Light modulating device 2 also can make to correct more even that light beam becomes, such as the hot spot of light beam is wider on the slow-axis direction of convex lens, narrow on quick shaft direction, when after these convex lens, the hot spot of light beam broadens on quick shaft direction, thereby improves the uniformity of correcting light beam.Certainly, need also can adopt speculum and concavees lens according to difference.
Wherein, in the present embodiment the optical axis of at least one convex lens with and its corresponding laser 1 in the central axis of light-emitting area of laser chip 11 do not overlap.The technical program can make arbitrary outgoing beam propagate according to either direction, can effectively solve because laser chip 11 and collimating lens 12 exist error to cause outgoing beam not propagate the problem that this laser cannot normally be used according to predetermined direction when mounted.
The technique scheme of the present embodiment has solved in prior art and can not propagate and cause the utilance of light low according to predetermined direction because industrial error causes the outgoing beam of multiple lasers, the outgoing beam of various lasers intersects mutually, and direction is inconsistent makes the problem that outgoing beam dispersion angle is large, laser facula is large.The technique scheme of the present embodiment adopts Light modulating device to correct the outgoing beam of multiple lasers, the outgoing beam of each laser all can be propagated according to predetermined direction, thereby the utilance of the light of this laser is increased, reduce the difficulty of the follow-up processing to outgoing beam.Meanwhile, also reduce industrial difficulty of processing, increased the range of application of laser.
Based on the first embodiment, the utility model proposes the second embodiment, describe below in conjunction with Fig. 2 A, 2B.A kind of laser facula correction system, comprises laser array, Light modulating device 2 and collective optics 3.Wherein, laser array comprises at least two lasers 1.Laser diode 3 is positioned at Light modulating device 2 away from laser 1 one sides, for the rectification light beam from described Light modulating device is converged.
Wherein, collective optics 3 can be the element converging correcting light beam arbitrarily, for example: concave mirror, convex lens etc.Wherein, this concave mirror can converge at the light beam inciding on it a bit, as shown in Figure 2 B, this concave mirror has a focus, and when light beam is during according to certain direction incident, this light beam can be converged at a bit, wherein, while inciding on concave mirror by regulating position, the direction etc. of Light modulating device 2 to regulate to correct light beam the position that arrives concave mirror, making to correct light beam, concave mirror converges rectification light beam.These convex lens can converge at the light beam inciding on it a bit, as shown in Figure 2 A, while inciding on convex lens by regulating position, the direction etc. of Light modulating device 2 to regulate to correct light beam the position that arrives convex lens, making to correct light beam, convex lens converge rectification light beam.This technical scheme of the present embodiment, Light modulating device 2 is corrected with the spherical aberration that convex lens are realized multiple lasers jointly, thereby can obtain less laser facula, and the optical density of this laser facula is higher, the efficiency of laser while improving follow-up use.
Light modulating device 2 in the first embodiment or the second embodiment in the utility model has also been realized the laser facula of the elliposoidal as in Fig. 3 A has been corrected into as the hot spot of the sub-circular in Fig. 3 B, thereby reduce the angle of divergence of outgoing beam, be convenient to the follow-up even light time can realize light and be more evenly distributed.Wherein, the laser facula in Fig. 3 A is the hot spot from the outgoing beam in laser, and the laser facula in Fig. 3 B is the hot spot from the rectification light beam after regulating through Light modulating device 2.For clearer explanation, Light modulating device 2 is convex lens for example herein, after outgoing beam arrives convex lens, the major axis of the ellipse light spot of outgoing beam is propagated along the slow axis of convex lens, the minor axis of ellipse light spot is propagated along the fast axle of convex lens, because fast axle is propagated the speed of light beam faster than the speed of slow axis propagation light beam, again because lens have certain effect of converging, thereby the width of the hot spot of the light beam of propagating on fast axle is broadened, and angle diminishes, thereby form as the hot spot of the sub-circular in Fig. 3 B.
The utility model also comprises a kind of projection display equipment, comprise the laser facula correction system described in above-mentioned arbitrary embodiment, this structure is not described in detail at this, the structure of this projection display equipment is except the Lights section adopts laser facula correction system, and other structures are the structure that those skilled in the art know.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; everyly utilize the equivalent structure that the utility model specification and accompanying drawing content do or directly, be indirectly used in other relevant technical fields, being all considered as being included in scope of patent protection of the present utility model.
