LEDs have many advantages over incandescent light sources, including lower power consumption, a longer lifetime, improved physical robustness, smaller sizes, and faster switching. LEDs have also given rise to new types of displays and sensors, while their high switching rates are useful in advanced communications technology with applications as diverse as aviation lighting, fairy lights, strip lights, automotive headlamps, advertising, general lighting, traffic signals, camera flashes, lighted wallpaper, horticultural grow lights, and medical devices. Later developments produced LEDs available in visible, ultraviolet (UV), and infrared wavelengths with high, low, or intermediate light output, for instance, white LEDs suitable for room and outdoor area lighting. The first visible-light LEDs were of low intensity and limited to red.Įarly LEDs were often used as indicator lamps, replacing small incandescent bulbs, and in seven-segment displays. Infrared LEDs are used in remote-control circuits, such as those used with a wide variety of consumer electronics. Īppearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared (IR) light. White light is obtained by using multiple semiconductors or a layer of light-emitting phosphor on the semiconductor device. ![]() The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. A bulb-shaped modern retrofit LED lamp with aluminum heat sink, a light diffusing dome and E27 screw base, using a built-in power supply working on mains voltageĪ light-emitting diode ( LED) is a semiconductor device that emits light when current flows through it. Close-up image of a surface mount LED Close-up of an LED with the voltage being increased and decreased to show a detailed view of its operation. The flat bottom surfaces of the anvil and post embedded inside the epoxy act as anchors, to prevent the conductors from being forcefully pulled out via mechanical strain or vibration. ![]() Make the switch to LED flat panel lights today for an energy-saving light that saves on bills while lasting twice as long as its more traditional fluorescent counterpart.Parts of a conventional LED. Suitable for both retrofit and new construction office and conference room lighting. The LED provides a uniformly crisp, bright light while cutting energy costs. Rectangular led panel fixtures are ideal for illuminating office spaces, and are an easy replacement for fluorescent recessed ceilings. With a lifetime of some 50,000 hours, the no-glare LED panel is built for purpose. The recessed LED panels replace fluorescent troffers and are ideal for all locations which require commercial fixtures, including office buildings, schools, retail spaces, hotels and hospitals.
