lens is a kind of made of transparent material for spherical surface part of the optical element. Are usually used PC lens and the glass lens two solar street lamps, these two lenses with different features, many customers don't know should choose PC lens or glass lens. 炥 xin lighting on the characteristics of two kinds of lens.
a, glass lens:
generally adopts high transmittance glass, glass lens with high transparency, pure, clear, uniform texture features, and have good how much is a refractive power, solar street lamps can be used not only on the street, but also all kinds of high-end camera lens, microscope lens, high-grade light indispensable core parts. High light transmittance, glass lens can reach more than 92%, and the light loss is small, light range, more reliable and reasonable. Glass lens have long service life, generally can be used in outdoor environment for more than 10 years, will not affect the light transmittance. But the process is relatively complex, glass lens material demand is high, prices are relatively high.
2, PC lens:
PC lens because of its low cost, convenient production, take a large part of the lens on the market. However, due to the limitations of its own material, PC lens in outdoor use for a long time will have the following several problems, such as yellow color after long time use PC lens, electrostatic adsorption dust, meet bad weather deformation, etc, will affect the light transmittance of lens, make the street lamps, etc. The overall performance.
so, think solar street lamps, outdoor lamps lighting should choose glass lens, as far as possible to ensure the good performance of street lamps, benefit the people.
