The led
- 1. THE LED Group members: Andres Ladino Diego Avila
- 3. The inventor: Nick Holonyak, Jr. (born November 3, 1928, in Zeigler, Illinois) Useful Practically invented the first visible LED in 1962 while working as a consulting scientist at General Electric Company laboratory in Syracuse, New York and`ve Been Called "the father of the light-emitting diode "He is the John Bardeen Endowed Chair in Electrical and Computer Engineering and Physics and Professor of electrical and computer engineering at the University of Illinois at Urbana-Champaign WHERE I've Been Since 1963.
- 4. The led: light-emitting diode is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for other 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.
- 5. Light-emitting diodes Are Used in Applications as diverse as replacements for aviation lighting, automotive lighting (Particularly brake lamps, turn Signals and indicators) as well as in traffic Signals. The compact size, The Possibility of narrow bandwidth, switching speed, and extreme reliability of LEDs has allowed new text and video displays and sensors to Be Developed, while Their high switching rates are found Also Useful in advanced communications technology. Infrared LEDs Are Also Used in the remote control units of Many commercial products Including televisions, DVD players, and Other domestic appliances.
- 6. Using LED's as light fixtures. Until recently, the use of LED lighting was very low, its use was reduced almost to see if a device is working properly or just was on. This conception of the diodes in recent years has changed, are now beginning to be used for mass enlightenment such as public lighting and household. The reasons to possibly make this change and stop using the bulbs for so many years have been in force are:
- 7. - Size: For a luminosity similar to that of a light bulb, the size that occupy the corresponding LED would be much lower. What gives a greater capacity for integration. - Another benefit of this, is that having smaller can join many diodes with ease and thereby get even more light as a light bulb without ever reaching a tenth of its size. - Brightness: The brightness of an LED is usually lower than that of a bulb, but one advantage it has over this is that LED lighting is completely uniform throughout its surface, the opposite thing happens with a light bulb.
