Low Power Consumption and Long and Predictable Life Time

Low power consumption and long and predictable life time The lifetime of Led Street lights is usually 10 to 15 years which is three times the life of current technologies adopted. The LED’s also have low maintenance cost which adds to the benefit. Dimming LED’s can be dimmned at times when the use of the street lights is less like late nights and early mornings. Small package size High color rendering The color rendering index is the ability of a light source to correctly reproduce the colors of the objects in comparison to the normal light source. Quick turn on and off Unlike flourescent bulbs which take time to heat up once switched on LED’s turn on instantly. LED’s don’t have problem with hot ignition RoHS complaint free LED’s dont contain Hg/Pb and dont emit poisonous gases Less attraction to nocturnal insects Insects are sensitive to the UV-blue and green region of the light spectrum. Nocturnal insects are attracted to the emission of UV-blue and green light from conventional light sources. White LEDs, however, emit light in a small peak in the blue range and smaller in the green range, so nocturnal insects are less attracted to such light sources. Easy to design non glare lighting equipment Most LED street lights have a lens on the LED panel, which is designed to cast its light in a rectangular pattern, an advantage compared to traditional street lights, which typically have a reflector on the back side of a high-pressure sodium lamp. In this case much of the luminance of the light is lost and produces light pollution in the air and surrounding environment. Such street lights can also cause glare for drivers and pedestrians.
