LED Lighting – Next Generation Lighting Options

LED stands for light emitting diode, which is an LED bulb lighting source. LEDs create visible light using electrical motion along the semiconductor path. When electrons flow across the semiconductor, they create electromagnetic radiation. Some forms of electromagnetic radiation can take the form of visible light, which humans can feel through vision.

Technology emitting visible light with a diode itself is not new. Back in the 1970s, LEDs were already used in numerical displays and indicator lights. With the development of technology, LEDs are now widely used for all types of applications such as exit signs, luminaire accents, task lights, traffic signals, cove lighting, bottom lighting, signage and wall sconces.

There are a number of benefits to using LEDs for lighting. LEDs are small, have a long life circle and provide low heat output. They are durable and energy-efficient lighting fixtures and are therefore called “green” lights. Even more interesting, LED lights can be designed to meet special requests. Color changing, dimming and distribution can all be specifically designed according to the user’s wishes.

At present, LED lighting has dominated the exit and traffic signal market with energy saving features and maintenance costs. As for the architectural lighting market, demand is still limited to white light LED lamps. Many lighting designers are beginning to realize the flexibility of LED lighting designs 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 it competitive with many other light sources. They also still have poor color rendering problems, and it takes time to prove that LEDs really can last for decades when they are advertised. Such losses make many people hesitate to choose LED lights when buying lighting products. The main time LED lighting has not yet come.

Some more information about LED lighting

As a solid state semiconductor device, the LED unit is activated when electricity flows across the diode semiconductor crystal and causes electrons to move from a negative charge carrier to a positive charge carrier, and the energy produced by movement is converted to light.

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

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