Solid-state lighting (SSL) has evolved to the point where the light-emitting diode (LED) is now the preferred light source for many lighting applications. The LED lighting system is a mostly mature technology, and the LED market transformation is estimated to approach 50% by 2025. Organic light emitting diodes (OLEDs) for lighting applications are also on the horizon. Research and development work is now moving towards exploring how SSL can be customized and how to use lighting to gather information that brings greater value to both producers and users. The term "solid state" commonly refers to light Emitted by solid-state electroluminescence, Opposites to incandescent bulbs (using thermal radiation) or fluorescent tubes. Compared to incandescent lighting, SSL creates visible light with less heat generation and less power dissipation. The most common "white" LEDs convert blue light from a solid state device to a white (approximate) spectrum of light using photoluminescence, the same principle used in conventional fluorescent tubes.
The typically small mass of a solid state electronic lighting device provides greater resistance to shocks and vibrations compared to brittle glass tubes and long thin filament wires. They also eliminate evaporation of the filament, potentially increasing the life of the lighting device. Solid-state lighting is often used at traffic lights and is also frequently used in modern vehicle lights, street and parking lights, train marker lights, building exteriors, remote controls, etc. Control of the emission of light Of LEDs can be more effective by using the principles of non-image optics. Solid-state lighting has made significant advances in the industry. In the entertainment lighting industry, incandescent tungsten-halogen incandescent lamps are being replaced by solid-state lighting lamps.
