Project at a Glance

Contents on the CD Rom

  • A light-emitting diode (LED) is a semiconductor diode that emits incoherent narrow-spectrum light when electrically biased in the forward direction of the p-n junction. This effect is a form of electroluminescence. An LED is usually a small area source, often with extra optics added to the chip that shapes its radiation pattern. The color of the emitted light depends on the composition and condition of the semi conducting material used, and can be infrared, visible, or near-ultraviolet.
  • LED chips and wafers :-
    The semiconductor chip consists of active layers that emit the light and the substrate, which supports the structure and upon which the active layers are grown. As with computing chips, they are produced in wafer form and then cut into chips.
  • Packaged LEDs
    The LED package provides the following functions:
    protects the semi-conductor,
    provides contacts for the electronics, provides basic optics to direct light as required, and converts the narrow spectrum light from the diode into broad spectrum white light, typically by
    using a phosphor.
  • Lighting modules:
    The LED package is integrated into a module with the power and controlling electronics and additional optics. The module may contain more than one LED package to produce the required lumen output.
  • Lamps and lighting systems:
    The module is then integrated with the rest of the lighting system. It varies significantly
    depending on the application, but will generally consist of at least one LED module, a heatsink, the luminaire (lighting fixture) and the control system.
  • Blue LEDs are based on the wide band gap semiconductors GaN (gallium nitride) and InGaN (indium gallium nitride). They can be added to existing red and green LEDs to produce the impression of white light, though white LEDs today rarely use this principle. Ultraviolet LEDs are becoming available on the market, in a range of wavelengths. Most "white" LEDs in production today are based on an InGaN-GaN structure, and emit blue light of wavelengths between 450 nm and 470 nm blue Ga.
  • Originally, LEDs were available in three colors: Red, Green, and Amber (Blue could not be produced), but were typically used for indoor systems because of intensity and durability limitations for use outdoors. As technology improved manufacturers were able to produce displays that had the intensity and long life required for outdoor use, but were limited in viewing angle.
  • First there was Liquid Crystal Display technology (LCD) then there was plasma, then Surface-conduction Electron-emitter (SED). Now these three are about to be joined by a fourth flat screen technology, one that has the potential of being the roll-up, wallpaper screen of fiction. It's called OLED or Organic Light Emitting Diode technology and it promises to revolutionize almost everything that uses displays from cell phones, PDAs and keyboards, to computer monitors and HDTVs.
  • The Project to manufacture  Packaged LEDs comes under high technology electronic domain and has very wide applications and market
  • According to some consultants,the project can be accomplished by getting the technology and equipments from the dominant players in the world now and the Investment required to put up a plant will be in the order of about one million USD
