Street lamps are an indispensable and important item in people’s daily life. Since humans learned to control flames, they have learned how to get light in the dark. From bonfires, candles, tungsten lamps, incandescent lamps, fluorescent lamps, halogen lamps, high-pressure sodium lamps to LED lamps, people have never stopped researching street lamps, and the requirements for lamps are increasing, both in appearance and optical parameters. Good appearance design can create a pleasing appearance of lamps, and good light distribution gives lamps the core soul. Tianxiang is a street lamp manufacturer, and today I will share this knowledge with you.
Street lamp light distribution curve, also known as lighting curve or light curve, is a graph that describes the distribution of light intensity of a light source at different angles and distances. This curve is usually expressed in polar coordinates, where the angle represents the direction of the light source and the distance represents the position of the light source.
The main function of the street lamp light distribution curve is to help designers and engineers determine the layout and installation location of street lamps to achieve the best lighting effect. By analyzing the street light distribution curve, we can understand the light intensity of the street light at different angles and distances, so as to determine the parameters such as the height, spacing and number of street lights.
In road lighting, if the LED street light source is not distributed. The light type irradiated on the road surface will form a large circular light spot. Street lights without light distribution are prone to form partial dark areas and shadows, resulting in a “zebra effect”, which not only wastes energy, but also brings great inconvenience to night driving and creates safety hazards. In order to meet the requirements of brightness, illumination and uniformity of the road surface, and to make most of the light distributed on the road surface as much as possible, so as to improve the utilization rate of light and reduce unnecessary waste. It is necessary to distribute the light of LED street lights. The ideal situation is that the light type or light spot formed by the light output by the LED street lamp on the road surface is rectangular, and such light distribution has good road surface uniformity. Generally speaking, the best light distribution is to achieve a wide-angle “bat wing” light distribution.
Bat wing light distribution is a common road lighting light distribution, and its light distribution is similar to the shape of bat wings, providing more uniform lighting. The bat wing light distribution curve is a street lamp design scheme worthy of promotion and application. It can improve lighting effects, reduce light pollution, save energy, reduce glare, improve driving safety and driver’s visual comfort.
