LED Lighting – The Next Generation Lighting Choice

posted in: Latest News | 0

LED stands for light emitting diode, which is the lighting source of an LED bulb. An LED creates visible ray using the movement of electricity along the path of its semiconductor. As the electrons stream across the semiconductor, they create electromagnetic radiation. Some forms of this electromagnetic radiation can take the form of visible light, which humans can perceive via sight.

The technology of emitting visible ray with diodes itself is not new. Back in 1970s, LEDs were already used in numeric displays and indicator lights. With the development of technology, now LEDs have been used widely for all kinds of applications such as exit signs, accent luminaire, task lights, traffic signals, cove lighting, down lighting, signage and wall sconces.

There are a number of benefits in using LEDs for lighting. LEDs are small in size, have long life circle and give low heat output. They are durable and energy-efficient lighting fixtures and thus called “green” lights. What is more attractive, LED lamps can be designed to meet special demands. Color changing, dimming and distribution can all be specially designed as the users desire.Watch movie online The Transporter Refueled (2015)

Currently, LED lighting has been dominating the market of exit sign and traffic signals with its features of saving energy and maintenance cost. As for architectural lighting market, the demand is still limited to white light LED lamp. Many lighting designers begin to realize the design flexibility of LED lights and present the world with innovative LED lighting fixtures now and then.

What remains a problem is that white LEDs do not 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 can really last for decades as they are advertised. Such disadvantages make many people hesitate to choose LED lights when purchasing lighting products. The prime time of LED lighting is yet to come.

Some more information about LED lighting…

As solid state semiconductor device, LED units are activated when electricity runs across the diode semiconductor crystal and causes electrons to move from negative charge carriers to positive charge carriers, and the energy produced by the movement is converted into light.

The color of the light emitted by an LED lamp varies depending on the chemical composition of the material being used as the semiconductor crystal. Different materials result in different light colors such as white, deep blue, blue, green, yellow, amber, orange, red, bright red and deep red.

Using low-voltage and low current for operation, LED lights, however, produce more efficacies than incandescent lamps and rivaling fluorescent lamps. It is expected that the efficacy of LED light can achieve 100 lumens per watt or even more in near future.
