Solid-state lighting (SSL) is a type of

fluorescent lamps), or gas
.

white LEDs” convert blue light from a solid-state device to an (approximate) white light spectrum using photoluminescence
, the same principle used in conventional fluorescent tubes.

The typically small mass of a solid-state electronic lighting device provides for greater resistance to shock and vibration compared to brittle glass tubes/bulbs and long, thin filament wires. They also eliminate filament evaporation, potentially increasing the life span of the illumination device.

Solid-state lighting is often used in traffic lights and is also used in modern vehicle lights, street and parking lot lights, train marker lights, building exteriors, remote controls etc.[1] Controlling the light emission of LEDs may be done most effectively by using the principles of nonimaging optics.[2] Solid-state lighting has made significant advances in industry. In the entertainment lighting industry, standard incandescent tungsten-halogen lamps are being replaced by solid-state lighting fixtures.[3]
