Application
Solar power generation series --- plastic Fresnel collector lens
Plastic Fresnel collective lens and solar panels generally use the box design to achieve the expected results. The Fresnel concentrating lens in the solar cell array is a precision optical element, a precision fine threaded process that guarantees high refractive index and minimizing light loss; and high strength, high light transmittance and aging. The anti-UV radiation, low price, etc., to increase the power generation of solar cells. And install on a photovoltaic power generation system with a day tracker.
In order to improve the resolution, clarity, brightness of the projector, our company specializes in the Fresnel lens of this purpose. The threaded distance, and the tooth shape are rationalized. In order to raise the picture, increase the scope of the ladder correction, use an eccentricity of the lens spotlight, so that the projector is hoisting or placed on the desktop, can achieve a good viewing effect.

Q: What does the focal length mean? How to choose the focal length for solar light?
A: The lens is positive for the sun, and the spot is formed, and when the spot is the least, the distance from the center of the lens is focused.
Q: Can the lens do not have a circle of concentric circles? Can the cloudy sky can be plagued?

A: The lens is an acrylic material (not a glass!) Don't break the energetic, no one can use 10 years, on, after, it will slowly yellow, and the light transmittance is gradually reduced, and it needs to be replaced.
Q: My light needs to catch light, how should I choose a lens?
A: The Fresnel lens used on the light needs to be satisfied: 1: The temperature does not exceed 80 °; 2: The lamp is not scattered, must be in the center, can be a single-point source, or the C0B integrated block, lamp beads The distance between the lens position is the focal length, the focal length is appropriate, the outlet angle is the smallest, the focal length is large or small, and the outlet angle increases.
Q: Can the outer ring have a yellow radius to solve it?
A: You can use a diaphragm Fresnel lens or matte Fresnel lens to solve it, and the photographic lamp is used in this. Use the temperature to be in 80 degrees.
