Some little knowledge of LED street lights

LED streetlights are becoming increasingly popular as they're cheaper and more energy efficient. Ten percent of U.S. streetlights have already been converted to LEDs, and many more are on the way. While LEDs are more efficient than traditional bulbs, the brightness of the light may be too bright for night driving. LEDs tend to emit a blue hue, while normal bulbs emit a yellow one.

LED street lights are typically designed to provide uniform lighting over large areas. They have a precise beam pattern, excellent optical efficiency, and excellent vertical illuminance. Roadlights of this type can be classified into two basic types: transverse and lateral lighting. The primary difference between the two is beam pattern. This difference in light distribution will influence the lighting patterns. LED street lights have good uniformity for their entire area and can be installed on narrow or wide roads.

LEDs are faster than other lighting technologies. LEDs are more accurate in their ability to reproduce color. A higher color rendering index makes it easier for drivers to recognize objects in the road, which improves road safety. Additionally, LEDs are faster to turn on and off than other types of lamps. They don't have a delay between switching on and off, so they can be restarted immediately following a power failure or inadvertent turn-off.





LED road lights are becoming more popular with municipalities. The energy-efficient and long-lasting LEDs make them a great option for replacing older streetlights. Unlike traditional streetlights, they can save a city a significant amount of money on energy costs and maintenance. The American Medical Association policy statement emphasizes the importance of properly designing new lighting technologies, and the close relationship between light and health. So, it's time to upgrade your streetlights to LEDs.

LED street lights incorporate a thermal management technique to avoid premature failures. LEDs in streetlights are commonly used in high-traffic areas. A good thermal management system prevents premature failure due to thermal stress. A typical LED street light's PLCC package consists of a die-cast metal frame, an optical lens, and a heat sink. LED street lights are designed to withstand up to 500 hours of ultraviolet exposure.

LED streetlights also have the ability to target the spectral power distribution that is most effective for nighttime driving conditions. Using the proper spectral characteristics in the lighting system can improve the visibility of objects that are far off-axis. The human eye has two types of retinas, called rods and cones, which are responsible for visual acuity. These retinal structures have a peak in photopic light at 555 nm, and are relatively inactive during the day.
