LED streetlights to light up roads

CHANDIGARH: As a part of their initiative to use energy saving lights in the city, the administration has decided to replace the ordinary street lights with light emitting diodes (LED) ones in different sectors. This project would be extended to the entire city eventually.

In the coming months, LED street lights would be installed in Sectors 20, 21, 22, 23, 24, 25, 29, 30, 31, 32, 34, 35, 36, 37, 38, Dhanas, Maloya and Manimajra.

In comparison to the high pressure sodium lamp, these LED street light can save up to 50-70% energy and last longer. LED offers up to 8 times more brightness than the incandescent lamps without emissions that are harmful for the environment. Apart from this, these lights can be given a better direction. A highly-focused LED optical system projects a regular rectangular beam pattern, that reduces glare and help the vehicle drivers feel less fatigued.

The LED lights also come with the option of experimenting with differently-coloured elements to mix red, green and blue hues. For instance, during dusk and dawn, a combination of blue and green lights can be beamed to complement the red glow of the sun. This would also give better visibility to the drivers and pedestrians.
