What kind of lens is better for a small lens to work with a large led lamp head?

No matter whether you buy solar street light or city circuit lights, LED lamp head is indispensable, and LED lamp head is often ignored by everyone. Today, litelsolar, the manufacturer of led solar street light, will tell you about the problem of LED lamp head lens - small lens acts as big led lamp head Which lens is best to use? Led lamp head consists of three parts: 1. Shell, 2. Light source, 3. Power supply. The shell is further divided into: 1. aluminum alloy lampshade; 2. lens; 3. radiator; 4. aluminum substrate. So how important is the lens? Transmittance is an important attribute of a lens. Under the same power, a lens with high transmittance can make more light, achieve higher illuminance, and reduce the temperature of the lamp. Another function of the lens is to refract light. A good lens can make the light distribution of the lamp uniform, meet the average illuminance requirements of customers, make the naked eye look more comfortable, reduce light waste, and can meet high illuminance requirements with lower power. Energy saving and environmental protection are more in line with the habits of the human eye. Usually, there are two kinds of lenses commonly used by street lamp manufacturers: one is glass lens, and the other is PC lens. Among them, the glass lens is generally made of high transmittance glass, which has the characteristics of high transparency, purity, colorless and uniform texture, and has good refractive power, high light transmittance, up to 92% or more, and small light loss. more reliable and reasonable. The glass lens has a long service life and can generally be used in an outdoor environment for more than 10 years without discoloration and without affecting the light transmittance. However, the glass lens manufacturing process is relatively complex, the material requirements are high, and the price is relatively high. The PC lens has seized a large part of the lens market because of its low price and convenient production. However, due to the limitations of its own material, the PC lens will have the following problems when used outdoors for a long time, such as yellowing and discoloration of the PC lens after long-term use, electrostatic adsorption of dust, deformation in case of bad weather, etc., which will affect the transparency of the lens. The light rate reduces the overall performance of street lights, etc. What kind of lens is better for a small lens to work with a large led lamp head? Seeing here is not clear in everyone's mind! The manufacturer of led solar street light reminds everyone not to save money when buying solar street light and commercial led solar street light, but only look at the price. Sometimes looking the same does not mean the same quality. Check it out on the spot.
