What Is Solid State Lighting?

Solid-state lighting (abbreviation: SSL) refers to lighting technology that uses solid-state electronic components, that is, semiconductor components, such as light-emitting diodes, organic light-emitting semiconductors, and polymer light-emitting diodes, as light sources. This is in contrast to lighting technologies that use light sources such as traditional electric bulbs or fluorescent lamps.

In the last century, the solid-state lighting market was dominated by light sources such as incandescent, fluorescent, and xenon lamps. In 1879, Swan and Edison independently developed the first electric lights, based on the principle of black body light emission. Edison invented the first incandescent lamp using a carbonized sewing thread taken from his wife's sewing box. His first commercial product used carbonized bamboo fiber with a power of about 60W and more than 100 In hours, the efficiency is about 1.4 lumens / watt. After long-term development, the efficiency of the current incandescent lamp has reached 15 lumens / watt (120 volts / 60 watts), and the average life expectancy has reached 1,000 hours.
