LED lights
Light-emitting diodes (LEDs) contain solid semi-conductor materials that convert electrical impulses into light through a process of electroluminescence. LEDs may include fluorescent materials that alter the colour of the light.
LED lights are packaged arrays of light emitting diodes that create uniform and bright light. They have high electrical efficacy, good reliability, and long lifespan. This results in energy savings, lower maintenance costs, and good environmental performance.
An LED light fixture will typically use 90% less electricity than an equivalent incandescent fixture. They have a similar efficiency to compact fluorescent lamps (CFLs) but are longer lasting. A good quality LED light can have a useful life of 25,000 hours or more. This is more than 25 times longer than traditional light bulbs. LEDs also lack filaments or glass enclosures, making them more durable than traditional alternatives.
Wall washing, cove lighting, backlighting, in ground lighting, and speciality lighting are the prime applications for LED products. The global LED lighting market was valued at approximately USD 20.0 billion in 2014. The market is dominated by Europe, which accounted for more than 30% of total demand in 2014.
Solar LED products and conventional LED products are the two major segments of the global market. The conventional LED products segment dominates the market at present.
