LED Street Light The Key To Traditional Street Lights

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

LED street 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, the luminous efficiency and light distribution curve is two important parameters, the current LED lights with light the main program has the following basic form.

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 packaging lens technology and high-power LED street lighting a light distribution has a certain relationship. LED Street Light Through a good package lens design, LED can get better light output characteristics.

The use of double-headed lens package of 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.

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.

A plurality of LEDs are arranged to form an LED module. LED Street Light 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.

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

LED street 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, the luminous efficiency and light distribution curve is two important parameters, the current LED lights with light the main program has the following basic form.

In the power LED manufacturing process, LED Street Light the use of lens technology package can improve the light efficiency, reduce light output loss, LED Street Light change the light output characteristics, LED packaging 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 free-form lens LED secondary light distribution. In this design, the free-form surface optical element with asymmetric rectangular light distribution in the XY axis direction is used. For example, an evenly distributed light distribution of ± 60 ° is generated on the X-axis to meet the lighting requirements in the length direction of the road, and a uniform distribution of light distribution of ± 30 °LED Street Light  is generated on the Y-axis to obtain an LED "Batwing "Shaped with light. In the free surface design, the light distribution of the light source is matched with the illumination surface of the illumination target by including the differential equation method, the multi-parameter optimization method, LED Street Light the multi-surface simultaneous design method and the shear method.

LED street light design with XY direction asymmetric rectangular light distribution of the free surface optical components (lens or reflective cup), LED Street Light 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
