Street lighting (also known as pedestrian light) is extremely essential for driving in the night or dark. That is why it’s one most essential aspect for sustaining a smooth & secure traffic following dusk. With the increasing figure of vehicles & roads, demand for such kind of lighting is also augmenting. For several years now, diverse companies concerned with the production of such lightings have relished a massive demand. Till the 90s they employed incandescent bulbs which employed mercury vapors or high pressure sodium.

More number of pedestrian lightings means more power needed to lighten them up. Mercury and sodium bulbs use too much energy. In early 90s, the energy usage by these sorts of lamp went further than the expectation. The scientist began seeking an alternative which was energy efficient. Following many researches, LED pedestrian light appeared as the most reliable one. They not just use far less energy in comparison to the traditional mercury or sodium lamps, but also generate better light.

All these attributes made premier cities in Europe and US shift from the traditional ones to LED pedestrian lighting. Primarily, they struggled to produce eminence LED light and were incapable to substitute the more energy wasting lamps, but the technology became superior with time and in recent years most of the large employing LED street lighting unit. LEDs are now also quite extensively used as traffic signal controller in many big cities worldwide.

The intelligent traffic controller are an instance of integrated lighting. Generally a solitary high-power LED lamp is employed to make such intense lighting, but several companies these days have started employing a series of low power LED bulbs to have the identical outcome.

Conventional street lamp consist a reflector at the back of the bulb which generally sources a considerable loss of lighting which causes light pollution. The radiance generated by such lighting is also not good for the drivers. The LED ones generally have a lens on the LED panel, which not just stops the loss of lighting but also offers them a well defined rectangular pattern. They don’t generate any radiations as well.

On the whole, LED pedestrian lights have several advantages in comparison to the conventional lighting. The biggest gain is the lower energy usage. Besides being energy efficient, they’re environment friendly as well. The life span of these lights is 50000 -100000 hours which’s much more than any traditional light.

All these attributes make LED pedestrian lights a preferred to illuminate the roads and high traffic areas.
