What is an LED?
A light-emitting diode (LED) is a semiconductor device that emits narrow-spectrum light when electrically charged. An LED is a small bulb previously used in millions of physics experiments at school to demonstrate electrical current, use of switches etc. LED’s are being improved all the time to progress from experimental devices into the future of lighting technology.
LED is the common abbreviation for a light-emitting diode. Each individual LED consists of a semiconductor diode that emits light when a voltage is applied to it. The electronics industry has used LED technology for several decades as indicator lights for various electronic devices. In more recent years, LED technology has progressed to the point where it is viable for general lighting applications.
LED is the common abbreviation for a light-emitting diode. Each individual LED consists of a semiconductor diode that emits light when a voltage is applied to it. Unlike incandescent or fluorescent lamps, which create light with filaments and gases encased in a glass bulb, an LED is a semiconductor device, which emits visible light when an electric current passes through it. Advantages: · Durability and long life — LEDS in lighting fixtures can provide over 100,000 hours in solar applications. In comparison, an incandescent light bulb lasts approximately 1,000 hours. Energy and maintenance savings — can be powered by a solar array and require little maintenance because of their long life. Better quality of light – provide more than twice the luminous efficacy (lumens per watt) of incandescent lighting. Safer — LED systems are low voltage and are generally cool to the touch (energy is delivered in the visible spectrum). Smaller flexible light fixtures — resistant to vibration and shock
