LED Street Light The Design Of

LED light distribution program in the road lighting requirements on the basis of the same time to consider the control of glare and consider the environmental coefficient. For road lighting, LED Street Light the luminous efficiency and light distribution curve is two important parameters, the current LED lights with light the main program has the following basic forms.

In the power LED manufacturing process, LED Street Light the use of lens technology package can improve the 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, 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 when the incident angle is greater than the critical angle, the total reflection can occur. Using this principle, LED Street Light the axisymmetric total reflection lens is designed.

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 align the LED module On the plate can be.

A plurality of LEDs are arranged to form an LED module, LED Street Light and the LED on the LED module is optically aligned with an axially symmetric, totally reflective lens or reflector, 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 better road light distribution, respectively, the design of each group of LED projection direction is responsible for lighting their respective regions, LED Street Light the more simple way is to use V-shaped surface.

In the design of multi-fold face light distribution, the high power LED of each group in the street lamp is installed on different planes respectively. By adjusting the relative angle of each group,LED Street Light the light output characteristic and the approximate rectangular illumination effect of the street lamp are satisfied to meet the requirements of the road lighting standard Claim.
