LED Street Light The Key Factor

LED lights with light is to make the light as far as possible to be projected to the various areas of the road, LED Street Light in line with the requirements of road lighting light distribution, LED lights with light design is accurate in place whether it can replace the traditional one of the key factors.

In the road lighting, if there is no LED light source light, LED Street Light the light on the road surface for the larger circular spot, there will be part of the light scattered outside the road without being used

In order to meet the road surface brightness, LED Street Light illumination, uniformity requirements, LED Street Light and as much as possible so that most of the light are distributed in the road surface to improve the utilization of light to reduce unnecessary waste, usually need to LED light distribution, LED The light of the street light is illuminated. The light or light spot formed on the road surface is preferably rectangular

In the power LED manufacturing process, the use of lens technology package can improve light efficiency, reduce light output loss, change the light output characteristics, LED package lens technology and high-power LED street lighting a light distribution has a certain relationship. Through a good package lens design, LED can get better light output characteristics.

The use of double-headed lens package LED light distribution, can be a single LED light intensity output curve into a "bat wing" shape, LED Street Light in order to further achieve the overall light intensity of the overall output curve of the "bat wing" shaped light.

The use of all-reflective lens LED secondary light distribution. LED Street Light The light is directed from the relative optical density to the relative optical sparse medium, and the total reflection can occur when the incident angle is greater than the critical angle. Using this principle, LED Street Light the axisymmetric total reflection lens is designed.

The use of free-form lens LED secondary light distribution. In this design, the free surface optical element with asymmetric rectangular light distribution in the XY axis direction is used.

LED lights three times the light distribution is in the high-power LED on the basis of the completion of the second light, through a number of LED (unit module) superposition and space arrangement to meet the road lighting average brightness, average illumination and uniformity The request.

LED lights designed with XY-oriented asymmetric rectangular light distribution of the free surface optical components (lens or reflective cup), because the rectangular light distribution in a single LED optical components have been completed, so the entire LED lights only need to LED array On the plate can be.

A plurality of LEDs are arranged to form an LED module. The LED on the LED module is optically aligned with an axially symmetric, totally reflective lens or reflector, LED Street Light and the width of the radiation through the lens or reflector is sufficient to cover the width of the road.

LED light has a good direction, in order to obtain a better road light distribution, LED Street Light respectively, the design of each group of LED projection direction is responsible for lighting their respective regions, the more simple way is to use V-shaped surface.

Through the LED reflector design to get the street light output characteristics. LED Street Light For the individual LED design of the XY axis of the asymmetric reflector, LED Street Light this program is similar to the plane with light, the difference is the use of free-form surface reflector, LED Street Light to obtain light output close to the "bat wing" shape, the design of multiple reflectors And arranged in the same can get a better road lighting effect.
