LED’s possess a solid history of effectiveness in commercial applications. Most traffic signals incorporate LED’s. The normal traffic light will contain 196 LED’s but will draw 10 watts. To provide the same light requirement with incandescent lights might consume 150 watts. It is estimated that replacing all 260, 000 U. S. traffic signals now using incandescent would reduce electrical consumption by 2. 5 billion kWh on a yearly basis. This is just the end of the iceberg of savings with this one example.

Maintaining the incandescent light bulbs in all these traffic signals is far more expensive than the electro-mechanical consumption. With and average life of 2, 000 a long time, a typical signal will have to have the bulbs changed at the least 4 times a year. Some LED’s will last 15-20 years. The cost savings in the reduced replacement cycle should justify the price tag on replacing the existing lamps, even with a unit cost for LED’s which runs 50-60 times that of an incandescent bulb.

But the savings do not end here. If LED’s began to replace lighting in your broader scope of lighting both residential we’d see savings from the reduced need to build new power facilities, reduced emission from reduced power requirements for any plants to produce, reduced recycling cost to process the burned out fluorescent and incandescent bulbs and a host of other power and economic impacts attendant to lighting.
For the reason that electrons stream across the semiconductor, they create electromagnetic the radiation. Some forms of this electromagnetic radiation will take the form of seen light, which humans can perceive via sight.

The technological know-how of emitting visible beam with diodes itself is not really new. Back in 1970s, LEDs were already applied to numeric displays and indicator lights. With the progress of technology, now LEDs have ended up used widely for all kinds of applications such as stop signs, accent luminaire, task lights, traffic signals, cove lighting, down lighting, signage and wall sconces.

Web site of benefits in using LEDs for lighting. LEDs are small in size, have long life circle allow low heat output. They’re just durable and energy-efficient lighting fixtures and thus called “green” lights. What is more captivating, LED lamps can be designed to meet special demands. Colour changing, dimming and distribution are able to all be specially designed as the users desire.

Currently, LED lighting has been dominating this market of exit sign and traffic signals with its features of saving electrical power and maintenance cost. As to architectural lighting market, the demand holds limited to white light LED lamp. Many lighting designers will realize the design flexibility of LED lights and present the modern world with innovative LED lighting fixtures once in a while.

What remains an issue is that white LEDs don’t produce enough lumen output to make them competitive with many other light sources. They also still have the problem of poor color rendering, and it takes to time to prove that LEDs really can last for decades as they are advertised. Such disadvantages make many people hesitate to choose LED lights when purchasing illumination products. The prime time involving LED lighting is yet to come.
