'''Solid-state lighting''' ('''SSL''') is a type of [[lighting]] that uses [[light-emitting diode|semiconductor light-emitting diode]]s (LEDs), [[organic light-emitting diode]]s (OLED), or [[polymer light-emitting diode]]s (PLED) as sources of illumination rather than [[electrical filament]]s, [[Plasma (physics)|plasma]] (used in [[arc lamps]] such as [[fluorescent lamps]]), or [[gas lighting|gas]].

[[solid state (electronics)|Solid state]] electroluminescence is used in SSL, as opposed to incandescent bulbs (which use thermal radiation) or fluorescent tubes. Compared to incandescent lighting, SSL creates visible light with reduced heat generation and less energy dissipation. Most common "[[white LED]]s” 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 [[service life|life span]] of the [[illumination device]].
