Slowly But Steadily LED Traffic Lights Replacing The Typical Incandescent Halogen Bulbs

It can't be denied that LED lighting is pretty beneficial not just to people but also big business and social groups as well. LED stands for light-emitting diode, which itself is a semiconductor light source and since the year 1962, it has been adapted widely for various types of equipment to serve several purposes that require lights. Today, LED lighting is widely used for different purposes such as automotive lighting, LED traffic light and in aviation. LED lights are known to be reliable due to it having adjustable switching speed, narrow bandwidth and compact size to name a few. Regardless of its shape and size, a LED is composed of a wire bond, reflective cavity, epoxy lens, a semiconductor die, an anvil post (the lead frame), a flat spot or surface, cathode (negative) and anode (positive).

You may have noticed an array of bulbs inside of traffic signal lights instead of the typical incandescent halogen bulbs. These lights in an array or LEDs (Light Emitting Diodes) are an efficient substitute to typical incandescent halogen bulbs inside traffic lights. Not only do they have a longer lifespan but they are much more energy efficient than incandescent bulbs. The longer lifespan also means lower overall maintenance costs.

Typical incandescent halogen bulbs last for a few months and the constant replacement carries a great financial toll. Traffic has to be stopped while the bulbs are being replaced. It costs a great deal of money to hire the repair people and trucks every time the traffic bulbs need to be replaced. Also, the replacement intervals are short when compared to LED units.

Also worth noting is that fact that LED are very durable and their daily use can last from fifty thousand hours to as long as one hundred thousand hours. That is a hundred times better than incandescent lights and around ten times better than fluorescents.

The advantages in energy consumption and operational maintenance costs of LED traffic signals outweigh the typical incandescent traffic signals. As a result many cities and town are choosing to go with LEDs for their traffic light modules.
