Abstract
The utility model relates to a remote laser zooming lighting device. The technical scheme is that the remote laser zooming lighting device comprises a laser component and an optical zooming mechanism, wherein the optical zooming mechanism comprises a convex lens and a concave lens which move back and forth respectively from the side of an object in sequence along an optical axis, and during zooming of the optical zooming mechanism, the spot diameter at a diaphragm is unchanged and is equal to the aperture of the diaphragm. For remote monitoring, zooming lighting has obvious advantages than lighting with fixed focus, and a lighting angle can be continuously adjusted, so that the requirement on laser illuminance and different lighting angles is met when a video camera is used for observing far and near objects.
Description
Technical field
The utility model relates to a kind of laser lighting technology, especially relates to a kind of long distance laser zooming illuminating apparatus.
Background technology

Summary of the invention
The utility model is to the existing in prior technology shortcoming; Provide a kind of simple in structure, design the technical scheme of long distance laser zooming illuminating apparatus cleverly; The light angle size of present technique scheme is adjustable continuously, in the time of can satisfying the far and near different objects of cameras view to the demand of laser illumination and different light angles.
The utility model is realized through following technical measures: a kind of long distance laser zooming illuminating apparatus; Comprise laser assembly, optical zoom mechanic; Said optical zoom mechanic comprises and disposes the convex lens and the concavees lens that can move forward and backward respectively along optical axis from object side successively; Said optical zoom mechanic is in the zoom process, and the spot diameter at diaphragm place is constant and identical with the aperture of diaphragm.For remote monitor, the zoom light ratio focuses illumination has tangible advantage, and its light angle size is adjustable continuously, in the time of can satisfying the far and near different objects of cameras view to the demand of laser illumination and different light angles.
The zoom transmission component that above-mentioned optical zoom mechanic comprises sliding sleeve, is connected with sliding sleeve; Sliding sleeve is provided with two cam paths; Said concavees lens and convex lens are installed in respectively on the forward and backward mirror holder, and said forward and backward mirror holder is sleeved in the mirror body, and said mirror body is provided with the gathering sill that forward and backward sliding guide moves; Be fixed with forward and backward sliding guide on the said forward and backward mirror holder, the other end of said forward and backward sliding guide passes said gathering sill and slides and is flush-mounted in the corresponding cam path of sliding sleeve.
Above-mentioned laser assembly comprises semiconductor laser, semiconductor laser optical fiber coupling output tail optical fiber, fiber optic connector, and said semiconductor laser optical fiber coupling output tail optical fiber inserts optical zoom mechanic through fiber optic connector.Its light source is that optical fiber coupling output semiconductor laser is done light source, connects as optical fiber coupling output to have versatility, can realize compatibility and the versatility of light optics zoom mechanism to the different capacity light source.
The optical position that goes out of above-mentioned semiconductor laser optical fiber coupling output tail optical fiber does not satisfy image space all the time with optical zoom mechanic and concerns.The logical light area of low-angle concavees lens is less, thus during low-angle the optical fiber light output end approximate be positioned at concave lens focus with near, whether near the hot spot the focus can be described with being approximated to picture, but perfect imaging so hot spot avoid producing imaging facula; The logical light area of wide-angle two lens combinations is suitable, and concavees lens and convex lens are because spherical aberration is opposite, so spherical aberration corrector each other makes and the hot spot edge clear neither form images at this moment that hot spot also is to be in the homogenize state.Promptly in whole angle change procedure, do not have clear state of tangible hot spot and homogenize state variation, just be in homogenize state, hot spot uniformity all the time all the time.
Above-mentioned zoom transmission component comprises motor, is fixed with driving gear on the motor output shaft, the engagement of said driving gear and driven gear, said driven gear is fixedly connected with sliding sleeve, said driven gear also with the synchronizing potential device on fixed gear mesh.Adopt electronic control mode, can realize the adjustable continuously of laser lighting angle, the angle excursion can reach 0.5 °～17 °, and can reach with remote camera lens and cooperate synchronous zoom.
The beneficial effect of the utility model is: it is simple in structure, design is ingenious; Lens in the optical zoom mechanic are realized focal length variations through aggregate motion; Thereby change rising angle; The diaphragm place spot diameter of optical zoom mechanic is constant all the time in whole angle change procedure, thereby makes in whole angle change procedure, and laser instrument veiling glare and optical zoom mechanic sliding sleeve reverberation can be eliminated under the control of the diaphragm at this place; Also be equipped with in this technical scheme can the output potential value the synchronizing potential device, the corresponding potential value in the time of can obtaining different shooting angle, thus accurately orientation angle changes, thereby cooperates the realization synchronous zoom with the video camera zoom.
