Brief History of Solid-State Lighting Technology

On June 5, 2013, in

Semiconductor electroluminescence was first reported by H.J. Round in 1907, and the first light-emitting diode (LED) was reported by O.V. Losev in 1927. Not until the birth of semiconductor physics in the 1940s and 1950s, however, was scientific development of technologies for light emission possible. For solid-state lighting (SSL), using semiconductor electroluminescence to produce visible […]
