Description
Technical field:
The utility model relates to a kind of video display stage projector, specifically is a kind of varifocal LED video display stage projector that is used for multiple places such as arenas, studio.
Background technology:
At present, the LED lamp applications is comparatively extensive, is characterized in energy-saving and environmental protection, long service life.But single LEDs power is little, and wanting to improve power increases brightness, can only take many integrated modes.The LED light fixture adopts single LEDs to add convex lens, reflector, also can realize optically focused, astigmatism after many combinations, but shortcoming is to realize the poly-adjusting continuously of loosing in same light fixture, and the light source assembly physical dimension with constant power can be very big, lamp body is corresponding also to be increased, increase manufacturing cost, be unsuitable for the video display stage and use.The lamp light source that present each performance theater, studio are used generally all adopts halogen tungsten lamp.Halogen tungsten lamp is a thermal light source, and consumed power is big, and heat radiation is big, luminous efficacy is low.Want to satisfy the performance needs and must improve lamp power, increase light fixture quantity, increase cost like this, consumes energy is made troubles to the user.Therefore, a kind of high brightness video display stage projector that is used in led light source in the video display spotlight and can regulates optically focused, astigmatism of development is in the market a urgent need.
Summary of the invention:
The purpose of this utility model is to solve existing stage projector above shortcomings, provide a kind of adopt led array module illuminator, high-power, light efficiency is high, can regulate optically focused simultaneously, the LED video display stage projector of astigmatism.
The utility model is achieved through the following technical solutions:
A kind of varifocal LED video display stage projector comprises light source, radiator, the fan installed in lamp body, the lamp body, power supply, described light source adopts the led array module, be equiped with leading screw below the led array module, an end of leading screw is equipped with adjusting knob, and slide is housed on the leading screw; Described led array module is installed on the slide by light source bracket; Non-spherical lens is equipped with in front at the led array module, is equipped with and the corresponding Fresnel lens of non-spherical lens at the light-emitting window of lamp body.
Described led array module, is fixed on the holder on soaking plate by the plurality of LEDs array combination again.
The lens retainer plate is equipped with in the outer ring that is installed on the non-spherical lens in led array module front, and non-spherical lens is fixed on the holder by the lens retainer plate.
Described radiator is adhered to the back side of led array module with heat conductive silica gel, and described fan is fixed in the radiator rear.
The light source of the varifocal LED video display of the utility model stage projector adopts the plurality of LEDs array combination, and power can reach 100-400W, the luminous efficiency height.The plurality of LEDs array combination is encapsulated on the soaking plate, pastes with heat conductive silica gel and radiator again, have good performance of heat dissipation.Cause heat flow density big because of plurality of LEDs is densely arranged together, the bad LED illumination that will cause decays if dispel the heat, LED wears out and reduces service life, so except an affixed fan on the radiator at the led array module back side, also install a fan in the rear end of lamp body.During work, in time the heat of illuminator led array module generation is discharged with the fan that radiator is fixed together, the fan of rear end sucks lamp body with the outer cold wind of lamp body in the lamp body, and environment temperature in the reduction lamp body makes LED keep normal room temperature work.
Led array module in the utility model is similar to area source.The non-spherical lens in led array module front can be assembled the area source scattered light, shines the Fresnel lens in the place ahead again.At this moment, regulate the relative distance of light source assembly and Fresnel lens, just can change the beam angle size, realize optically focused, astigmatism.
The beneficial effects of the utility model are:
1, the utility model uses the led array module, with non-spherical lens and Fresnel lens, can change the beam angle size, realizes adjustable optically focused and astigmatism, satisfies the special requirement of video display stage illumination, lighting.
2, energy savings.The varifocal LED video display of the utility model stage projector light efficiency height, light efficiency be halogen tungsten lamp 5-6 doubly, long service life, be halogen tungsten lamp 60-120 doubly.
3, LED is applied to the video display stage projector, makes the light fixture miniaturization, and easy to operate, application prospect is extensive.
