Description
Technical field
The utility model relates to a kind of video display stage equipment, particularly relates to a kind of video display stage lamp that has square light-distribution lens.
Technical background
At present, domestic video display stage illumination, lighting light fixture market has emerged the new lamp of many employing large-power LED light beads as light source.Efficiently, energy-conservation, service life is extraordinary etc., and plurality of advantages makes LED video display light fixture become a unexpected rival in this market.The same with traditional video display stage lamp, the hot spot that LED video display stage lamp penetrates also is circular.In the middle of the video display stage illumination, lighting, the lamplight object mainly is personage and stage, recording equipment view finder and our picture seen side of being all, modal is 4: 3 rectangles.That is to say that the circular light spot that light fixture sends can " be cut " by the camera lens of camera-shooting and recording device and become a square Free Region, suppose 1 meter of the diameter position of circular light spot, then video camera is 0.8 * 0.6 meter at the maximum of the effective light area area of finding a view.
Facula area: 3.1416 * 0.5 * 0.5=0.785
Maximum usable area: 0.8 * 0.6=0.48
Maximum utilization ratio: 0.48 ÷, 0.785 * 100%=61%
Learn to have at least 39% light loss to lose as calculated.
In the middle of reality, the shape of stage, scene all is square or approaching square.If adopt traditional light fixture with circular light spot to carry out lighting, have two kinds of situations: lighting inequality or light source are overstocked, cause the wasting of resources.Suppose stage be 8 meters wide 6 meters dark, the circular light spot diameter of conventional lamp is 2 meters, can cause the lighting inequality with 12 desk lamps, then causes light source waste with 18 desk lamps, reduces the uniformity.
The utility model content
The purpose of this utility model is to provide a kind of video display stage lamp that has square light-distribution lens at the many weak points that have video display stage lamp circular light spot now.
In order to achieve the above object by the following technical solutions: a kind of video display stage lamp that has square light-distribution lens, comprise housing, illuminator and wiring board are housed in the housing, in the illuminator front square light-distribution lens is housed.
Described square light-distribution lens comprises framework and the uniform individual lenses that is arranged on the framework.
Institute's individual lenses is at least one; The color of individual lenses is a red, green, blue or transparent.
Described square light-distribution lens is fixed on above the illuminator.
For flexibly connecting, square light-distribution lens is positioned at the illuminator front between described square light-distribution lens and the housing.
Housing is provided with lamp bracket or handle.
Described active link be hinged, card is inserted, screw is fastening or binding.
Described square light-distribution lens is hinged on left side, right side, top or the bottom in housing front.
Described illuminator can be the one or any several combination in LED lamp pearl, based on halogen bulb, three primary colours cold light fluorescent tube, inert gas bulb, the laser body.
The framework outward appearance of described square light-distribution lens is rectangle, ellipse, parallelogram, trapezoidal, circular or square.
Adopt the utility model to have the video display stage lamp of square light-distribution lens, aspect shooting, the square focus spot that forms and the hot spot of similar rectangle and the shape of machine picture are consistent, therefore can maximally utilise light source, thereby saved limited battery power, made picture pick-up device obtain the longer working time.Aspect the stage lighting, adopt the utility model then can finish lighting very easily, the uniformity is very high again, improve efficient, reduced the light fixture usage quantity, reduced debug time, reduced fault rate, saved electric energy, very high social benefit and economic benefit have been arranged.
