What Is the Role of Light Distribution in Street Lighting

Curry Law

Road lighting plays a very important role in street lighting. As the lighting of urban roads, LED street lights should be able to provide a good visual environment for drivers and pedestrians of various means of transportation, to ensure traffic safety, improve traffic rates, facilitate people's lives, reduce crime rates and beautify the urban environment.

The optic design of LED street light is to obtain a reasonable light distribution, so that the illumination range and luminosity curve (light distribution curve) of street lamps with a certain luminous flux meet or exceed road lighting (including average road brightness, total uniformity, longitudinal uniformity, technical parameters such as glare limit, environmental ratio, etc.), and meet the requirements of energy saving at the same time.

AGC lighting pays a lot of attention to the importance of light distribution. The light distribution of our products is diverse and complete, which can meet the needs of various places.

ST33-UNICO (CE, ENEC, ETL, DLC) is a beautiful and slim LED street light designed with excellent choice for new construction or retrofit application. High output LED and 30W-200W makes the power as a whole series.

ST33-UNICO (CE, ENEC, ETL, DLC) has 10 distributions and they are R01601 (Type I short), R01602 (Type II Short), R01603 (Type II Short), R01610 (Type II Short), R01604 (Type IV Short), R01605 (Type V Short), R01606 (Type II Short), R01609 (Type II Short), R01611 (Type II Medium), R01613 (TypeⅢ Medium). And we can customize the distribution for exact project according to clients’ needs to get the best lighting solution.

The light distribution of street lighting fixtures cannot fully illuminate the road surface. Such a light distribution is not even desirable for health or practical reasons. In highly urbanized areas, where roads are dense, buildings are close together, and strong street lights can disrupt the life and tranquility of residents. To illuminate cities and streets, another solution is used, the so-called negative contrast. It involves exposing the silhouette of a car or pedestrian, rather than illuminating the space entirely. This approach saves energy consumption and precisely locates light. Correctly chosen light distribution will increase the safety of traffic participants and create  a comfortable environment.

For complex lighting, it is best to use LED technology, which has low power consumption and can achieve a strong luminous flux. In addition to high parameters, the possibility of smooth adjustment of light intensity or distribution is equally important. Precise guidance of the optical flow reduces the risk of glare or light pollution effects. Also worth mentioning are the benefits of power saving, which reduces operating costs while extending the life of the light source.
