Description
Technical field
The utility model belongs to optics light fixture class, relates in particular to backdeeps shooting lighting class.
Background technology
Underwater camera is to explore a kind of technological means commonly used such as geography, biology, physics, chemistry, mineral reserve under rivers, the ocean water.Reasons such as common chemical analysis, light refraction, reflection owing to seawater, its underwater camera quality serious degradation, its reason mainly contains:
1, because seawater is much bigger to the absorptance air of light, it is airborne 1/1000 that visual range has only, and below 100 meters, is exactly dark world in the depth of water basically therefore.
2, because the various particles in the water have strong scattering to light, dim a slice in the water, the contrast of scenery descend rapidly with the increase of distance.
3, because water is selectively to the scattering and the absorption of light, absorb less in the 440-560nm scope.And outside this scope, absorb and to increase rapidly, so that white light transmits in seawater behind the segment distance is seriously weak, remaining green glow only basically.
4, because the refractive index of seawater changes with the degree of depth, temperature, current, fluctuation, disturbance, so the image in the water is often disturbed and is out of shape.Simultaneously, underwater camera is subjected to the restriction of many conditions, as: distance is near, color colour cast etc.
Be the needs of the aspects such as secret of exploring the ocean, people adopt often in ocean underwater camera, photography at present:
1, high-power white light illumination is to improve shooting, photo distance.
2, the green laser illumination reaches farther shooting and measuring distance.
Though these methods can solve partial colour shooting, photography problem, and the problem that solves colour cast and distance is also had any problem.
As: increase light intensity, can improve illuminance really.But because the strong scattering process of seawater, backscatter light also strengthens thereupon, greatly reduces the contrast of image.
Secondly, because seawater is very inhomogeneous to the absorption of different wave length light, so the image of taking is all green partially.
Also have, though the brightness of laser is very high, it can produce the interference speckle, has a strong impact on the sharpness of image.Therefore the color of underwater photography, clear image etc. all are subjected to many influences.
Summary of the invention
The purpose of this utility model provides a kind of LED illuminating lamp of underwater camera colourity compensation, to solve an above-mentioned difficult problem.
The purpose of this utility model is achieved in that a kind of LED illuminating lamp of underwater camera colourity compensation, and it is provided with pedestal in the compensating illumination lamp box, and top one side of pedestal is provided with group strake LED electroluminescent lamp, and opposite side is provided with condenser.The compensating illumination lamp box is positioned at the condenser place and is provided with the resistance to compression windowpane, and the bottom is provided with outside input socket in the compensating illumination lamp box, and input socket also has lead to be connected with group strake LED electroluminescent lamp.
Because the utility model has adopted above technical scheme, but the active light source that it adopts Be Controlled such as colourity and intensity to change, and according to the operating depth of underwater photography, shooting, subject distance, waters parameter etc., the intensity of illumination and the colourity of required compensating illumination light source are provided, thereby, can obtain the color image of realistic colour under water during shooting by the compensating illumination light source that the utility model is launched.The needs that also be fit under water simultaneously, throw light in many places such as the colored shooting in deep-sea, (water) down-hole shooting, diving operation, underwater construction, subsea equipment maintenance, underwater robot vision system.And have characteristics of simple structure, easy to operate, many aspects such as compensation shooting color effect is good.
