Light Emitting Diode, a semiconductor diode that glowswhen a voltage is applied. It is also called assemiconductor light source that converts electrical energyinto light energy. LED is a tiny light source that fit easily intoan electrical circuit.they do not have a filament that will burn out.What is LED ?
Short History The LED started life in October 1962 by Nick Holonyak Jr, as a single red illumination in aGeneral Electric research lab in New York state. Monsanto develops the first commercially available LEDs for HP35 Calculator In 1976 – T.P.Pearsall creates the first high-brightness high efficiency LED’s for optical fibertransmission wavelengths. In 1980 – LED development continues along the lines of increasing light output whilemaintaining efficiency and reliability. In 1997 – Nicha Corporation develops the first high brightness Bluish-Green and Blue LED’s inthe world. Philips Lumileds introduced power LED’s capable of continuous use at 1watt in 1999. TheseLED’s used much larger semiconductor die sizes to handle the large power inputs. Now : The LED lighting revolution begins with the first official standardizations of LED’s andLED fixtures in many international countries. People are widely pay attention to this energysaving technology and LED lighting begin to flowering all over the world in peoples indoorand outdoor life.
Dimmable Environmental Friendly Directional Energy EfficientWhy LED ?
No Heat Quick Start Long Life Low Power ConsumptionWhy LED ?
LED Indoor ApplicationsIndoor lighting is usuallyaccomplished using light fixtures,and is a key part of interiordesign.LED can save energy in place ofusing traditional lighting, whichrepresents a major component ofenergy consumption in buildings.
LED Outdoor ApplicationsOutdoor lights are used to lightroadways and walkways at night.LED and photovoltaic luminariesto provide an energy-efficientalternative to traditional streetlight fixtures.
LED SignageIn the old days of variablemessage signs which usedincandescent bulbs . Now trend isLED .LED Signage makes a grandlook , environmental friendly ,visual branding and save energy.
LED Video Display ,Signals & More..A LED display is a video displaywhich uses light-emitting diodes.
