Light Emitting Questions
Technology Insight Report: Light Emitting Diode Or Led Technology In Lighting
Light Emitting Diode or LED Technology in lighting can be traced back to 1927 although it didn’t make an entrance into commercial applications till much later. Having taken a back seat for many years largely owing to its high production cost LED lighting is rapidly gaining ground in the lighting space in more recent times. With the increasing demand for greener, more energy efficient products as well as the environmental strain on energy resources in our times is LED technology the answer to the future of our lighting needs? Where is LED technology headed and does it have the research momentum and industrial backing to take on the light bulb which was perhaps the most life-changing invention of our time?
Introduction to Light-Emitting-Diode or LED Technology
A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices, and are increasingly used for lighting. Introduced as a practical electronic component in 1962, early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet and infrared wavelengths, with very high brightness.
The LED is based on the semiconductor diode. When a diode is forward biased (switched on), electrons are able to recombine with holes within the device, releasing energy in the form of photons. This effect is called electroluminescence and the color of the light (corresponding to the energy of the photon) is determined by the energy gap of the semiconductor. An LED is usually small in area (less than 1 mm2), and integrated optical components are used to shape its radiation pattern and assist in reflection. LEDs present many advantages over incandescent light sources including lower energy consumption, longer lifetime, improved robustness, smaller size, faster switching, and greater durability and reliability.
