Introduction:Along with the LED illumination popularization, LED the lamps and lanterns necessary part LED lens have also become the focal point.2007 year's end, our company spends several 1,000,000, the development and the official production produced the high efficiency LED lens.On the other hand the projecting apparatus with the Acrylic lens (Fresnel lens), the stage shoot the lamp and the solar energy focusing with the Fresnel lens.Use explanation: The Fresnel lens use in the LED photosource, gets up the increase light effect, enhances brightness the effect.Is opposite in the identical lens and the LED lamp, Focal length different, Distance is different, what establishes emergent light Angle willfully, single or many array LED lamp may act according to the demand design.Is suitable in the LED projecting light, seven color projecting lights, the flare, the scenery views the lanterns, the signal light, each kind of lamps and lanterns.Characteristic: The Fresnel lens ultra thin structure, ultra big Dimension, arbitrary shape cutting, the fine transmittance and more than the traditional convex lens merit, its weight is smaller than the convex lens, many kinds of situations are suitable.

Advantages:

Compared with traditional  spherical lenses of the same focal length ,fresnel lens has the advantages of lighter weight and thinner center while eliminating spherical aberration and improving the utilization of energy of light. The lens is suitable for replacing a special lens such as big-diameter lens.
