The light distribution of LED street lights is inseparable from the lens. Which lens is the best to choose?
LED street light products have been updated all the time, and people's various requirements for street light fixtures are improving. The good lighting light distribution design of LED street lights can bring people pleasing visual effects, and when it comes to light distribution, it is inseparable from the street light lens. .
The purpose of the lens is to distribute the light in a targeted manner rather than evenly distribute it over the entire space. The lens makes the light controllable, distributes the light illumination, reduces glare, makes the light more healthy and comfortable, and can provide a colorful lighting environment for life.
LED street lights are common utilities in daily life, and the requirements for the appearance and optical parameters of street lights are getting higher and higher. The irradiation angle of the traditional high-pressure sodium lamp is 360°, and it emits light in all directions, which wastes a lot of light efficiency. The LED street light is usually unidirectional, and the illumination angle is usually 120°. But to make the illumination angle of the street light wider or narrower, a lens is needed to intervene.
Lens is an important part of lighting fixtures, mainly used in LED street lights, LED flood lights, LED landscape lights, LED tunnel lights and other tools. There are two general types of lenses on the market:
1. Optical plastic lens: also known as PC lens, the product is formed by injection molding, it is easy to achieve aspherical concentrating, and reduce the macular phenomenon of the light spot; it has good oxidation resistance, and it will not turn yellow after long-term use. There are significant advantages in terms of cost. However, plastic lenses are slightly inferior in transmittance and high temperature resistance.
2. Glass lens: The glass material has the advantages of high temperature resistance, high transmittance, high hardness, high strength, and high chemical stability; at the same time, the glass lens has the disadvantages of heavy weight, brittleness, and high cost, so its use range is also limited. limitations.
The Shenzhen Yaorong Technology R&D team can customize the lens according to customer needs and the actual local road conditions, and then match the self-developed LED street lamps to optimize the brightness and heat dissipation of the street lamps.
