LED street lamp light distribution requirements

In road lighting, if not for the LED street lamp light source, light distribution and light irradiation on the pavement type for the circular light spot with larger area, there will be a part of the light scattered beyond the road without being used, typically need for LED street light with the light, LED street lamp light output on the road of light type or there is better to rectangle. In the process of power type LED manufacturing, packaging when the lens technology can improve the efficiency of light, reducing the loss of light output, change the light output characteristics, encapsulation of LED lens technology and high-power LED street lamp lighting has a certain relationship with light at a time. Through the lens of good packaging design, LED outdoor lights can obtain good light output characteristics. The total reflection lens LED the secondary light distribution. Headed by relatively light dense medium relatively light thin dielectric, can happen when the incident Angle is greater than the critical Angle of total, use this principle to design the axisymmetric total reflection lens. No matter what technology or solution, in terms of the LED street lamp light distribution, the light output characteristics meet the road lighting at night standard requirements, the use of the technology or solution has good value.
