By making use of a mechanical motor structure to control the one-way movement of the semiconductor laser or the both-way movement of the semiconductor laser and the lens device, the utility model realizes the electrical control of illuminating angles and the big changing range, furthermore, as the whole device adopts conventional equipment, the utility model has the advantages of the small size, the low cost and being convenient for realization.
Description
Technical field
The present invention relates to a kind of laser generator, refer more particularly to a kind of movable zooming device that is applied to the laser generator of safety-security area.
Technical background
At present, use laser generator on the market as lighting device, its Laser emission angle is generally all fixed, even remain with certain adjustable range in advance, but adjustable range is all smaller, and what mostly adopt is manual adjustments, in case regulate when installing, just be completely fixed, relatively be fit to be applied in the occasion of fixed range illumination.
In the time need being applied in the bigger occasion of far and near distance simultaneously, the illumination of said fixing angle just is difficult to reach requirement.Because target need be amplified when remote, pick-up lens changes to long burnt, and the visual field is little, requires light angle also smaller, just enough illumination can be arranged; And it is short burnt to need closely the time big visual field, pick-up lens to change to, and requires light angle also enough greatly, just can be full of whole visual field.If light angle is fixed, when being easy to cause pick-up lens length burnt, light angle is excessive, surpasses the visual field, and object illumination is not enough; And pick-up lens is when short burnt, and light angle is too little, can not be full of the visual field.
Summary of the invention
At the limitation of above-mentioned technology, the invention provides a kind of movable zooming device that can realize the electronic control of light angle, continuous variation on a large scale and the sufficient laser generator of illuminating ray.
The present invention is achieved through the following technical solutions:
A kind of movable zooming device of laser generator, comprise semiconductor laser, shaping Optical devices and lens devices, shaping Optical devices and lens devices are positioned at the same horizontal level of semiconductor laser front end successively, and the light source S after the shaping is positioned on the optical axis of lens devices, it is characterized in that: the lower end of described semiconductor laser is provided with one and drives its controlled mobile mechanical driving device; Described mechanical driving device is connected with motor.
As another kind of implementation of the present invention, the present invention also comprises following technology contents:
A kind of movable zooming device of laser generator, comprise semiconductor laser, shaping Optical devices and lens devices, shaping Optical devices and lens devices are positioned at the same horizontal level of semiconductor laser front end successively, and the light source S after the shaping is positioned on the optical axis of lens devices, it is characterized in that: an end of described mechanical driving device is connected with the lower end of semiconductor laser and lens devices simultaneously, and the other end is connected with motor; Semiconductor laser and lens devices are simultaneously controlled to be moved at horizontal level.
Described lens devices is simple lens or the combination of a plurality of eyeglass.
The present invention moves by unidirectional or semiconductor laser of mechanical motor structure control semiconductor laser and lens devices are two-way, and the relative position of lens devices and lasing light emitter is continuously changed, thus the variation continuously on a large scale of control light angle.
Its principle is as follows:
The light beam that semiconductor laser sends was generally about 10 ° (levels) X40 ° (vertically), by the shaping Optical devices, level and vertical divergence angle was made into basically identical (needed angle).Light beam is after the compression of lens devices angle after the shaping, and with the outgoing beam outgoing, the emergent light angle is relevant with distance L, and L is the distance between light source S and the lens devices.Motor will rotatablely move by mechanical driving device and be converted to rectilinear motion, and the drive semiconductor laser seesaws or drives semiconductor laser and the horizontal relative motion of lens devices simultaneously, adjustable range L, thereby the shooting angle of control outgoing beam.In the said apparatus motion, guarantee that all the time light source S is positioned on the optical axis of lens devices, whole optical system is coaxial.
The present invention has realized the electronic control of light angle, wide variation by adopting mechanical motor structure control semiconductor laser unidirectional or semiconductor laser is two-way mobile with lens devices; And whole device all adopts conventional equipment, and volume is little, and cost is low, realizes easy.
