Abstract
The utility model relates to a stage canopy projector, comprising a lamp house cover with the light emitting source inside; the lamp house cover is connected with LCD by the light condensing cylinder faced to light emitting source. The LCD is connected with drive plate by signal wires. The swing circle of LCD is connected with objective lens by guide bars, which can adjust the distance between the objective lens and LCD. The drive plate is connected with the switch of light emitting source, the power of drive plate and the interface connected with PC.LCD is positioned at the place of previous slides. An optical reflector is arranged beside the light emitting source for intensifying the light and can be provided with elevation fastening screw and lifting screw fastener. The utility model has the advantage that the stage canopy projector improves the projection effect dramatically by changing previous backward producing method due to adopting the liquid crystal projection art. The utility model also has the advantages of low cost, easy using and convenient maintenance.
Description
Technical field
The utility model relates to the projection magic lamp that uses when a kind of stage is performed, and particularly relates to a kind of stage canopy of the heavens projection magic lamp that utilizes the crystal projection technology and be made.
Background technology
Old-fashioned stage canopy of the heavens projection magic lamp, originally earlier will by professional stage artistic design teacher have drawing on the diaphragm base, composition, on color, there are not higher production technique and foundation of painting to be difficult to be drawn as lantern slide, be drawn as also to be installed in behind the lantern slide on the specific aluminum frame sheet fixing, then by lantern projection to the canopy of the heavens; Old-fashioned stage canopy of the heavens projection magic lamp has faced is abandoned, and there be limited evidence currently of has troupe to use in the middle of performance.
Stage performance light fixture usable range mainly is divided into two big regional Performance Area and canopy of the heavens districts.Current stage performance uses the kind of light fixture more and more, major part has all been done some different improvement at aspects such as the structure of light fixture, overall dimensions, illumination, colour temperature, the light velocity, color, patterns, kind has ordinary lamps and Computer lamp, and import and homemade multiple model are arranged.Yet these light fixtures all are to use in the scope of stage performance Performance Area, and the improvement of canopy of the heavens district light fixture almost seldom.
Summary of the invention
The purpose of this utility model is for the deficiency that addresses the above problem, and a kind of novel stage canopy of the heavens projection magic lamp is provided, and this stage canopy of the heavens projection magic lamp utilizes the crystal projection technology, has easy to usely, makes advantages such as effective.
The utility model is achieved through the following technical solutions: this stage canopy of the heavens projection magic lamp, include lamp box cover, and in lamp box cover, be provided with light emitting source, lamp box cover is connected with liquid crystal display by the optically focused lens barrel, and light emitting source is right against the optically focused lens barrel; Liquid crystal display is connected with drive plate by signal wire, and the rotation circle on the liquid crystal display is connected with object lens by guide rod, can regulate the distance between object lens and the liquid crystal display like this, makes the effect of projection better; Be connected with light emitting source Switching Power Supply, drive plate power supply and the interface that is connected with computer on the drive plate.
Stage recited above canopy of the heavens projection magic lamp, liquid crystal display is arranged on the position of original lantern slide.Be provided with the reflective mirror that is used to strengthen light on the light emitting source next door, light is better shone on the liquid crystal display, make projection more clear.
Stage recited above canopy of the heavens projection magic lamp, returning apparatus is useful on the elevation angle trip bolt of regulating liquid crystal display and promotes trip bolt on the projection magic lamp of the stage canopy of the heavens, can be by regulating elevation angle trip bolt and promoting the position that trip bolt is adjusted in projection on the canopy of the heavens.
The beneficial effects of the utility model: this stage canopy of the heavens projection magic lamp has been owing to adopted the crystal projection technology, thereby must become the method for producing of original backwardness, and drop shadow effect is improved than before greatly; And this stage canopy of the heavens projection magic lamp cost is low, uses simple, easy to maintenance.

Embodiment
Below in conjunction with specific embodiment the utility model is further described:
Embodiment 1: as shown in Figure 1, the fluorescent tube that is placed with the high colour temperature of usefulness import, high brightness in lamp box cover 1 is as light emitting source 2, be provided with reflective mirror 5 in the back of fluorescent tube, reflective mirror 5 makes and shines its surperficial light and can cross optically focused lens barrel 9 again and shine liquid crystal display 3, and liquid crystal display is connected with object lens 8 by rotation circle 11, guide rod 12; At the downside of stage canopy of the heavens projection magic lamp, also be provided with can regulate about it, the lifting trip bolt 14 at the elevation angle, elevation angle trip bolt 13.Wherein, circuit control system as shown in Figure 2, the Switching Power Supply 6 of computer 10, liquid crystal display 3, bulb, cooling electric fan 15, drive plate power supply 7 are connected with drive plate 4.
During use, open drive plate power supply 7, the Switching Power Supply 6 of bulb with the content of made in the computer 10, by liquid crystal display 3, projects on the canopy of the heavens through object lens 8.Regulate lifting trip bolt 14, elevation angle trip bolt 13 according to the height of want projection, again by regulating the rotation circle 11 of liquid crystal display 3 back, regulate distance between object lens 8 and the liquid crystal display 3 by the transmission of guide rod 12, with the image that reaches projection effect clearly.
