    2. Solid State Lighting It refers to a type of lighting that utilizes light-emitting diodes (LEDs), organic light-emitting diodes (OLED), or polymer light-emitting diodes (PLED) as sources of illumination rather than electrical filaments or gas. The term "solid state" refers to the fact that light in an LED is emitted from a solid objecta block of semiconductorrather than from a vacuum or gas tube, as is the case in traditional incandescent light bulbs and fluorescent lamps 8/23/2012 GNIEM, Nagpur IIES-2011

    4. Todays Market For Conventional Lighting

    5. Importance of SSL Lamps based on the Hg-discharge provide nowadays about 50% of artificial light. Safe disposal of the burnt Hg lamps is a serious problem as Hg is potentially hazardous causing environmental pollution. These lamps are now phased out and lamps based on LED are used in developed countries. With the advent of GaN technology LEDs emitting around 390 nm have become available. These diodes are coated with phosphor blend, which on excitation by 390 nm emit in white. During last decade solid state lighting has emerged as a new area. No work has been done in India on development of phosphors for solid state lighting. It is likely that our country will go for large-scale import of such phosphors during next decade. It is fruitful to develop our own phosphors. 8/23/2012 GNIEM, Nagpur IIES-2011
