Light-emitting diodes (LEDs) produce light (or infrared radiation) by the recombination of electrons and electron holes in a semiconductor, a process called "electroluminescence". The wavelength of the light produced depends on the energy band gap of the semiconductors used. Since these materials have a high index of refraction, design features of the devices such as special optical coatings and die shape are required to efficiently emit light. A LED is a long-lived light source, b… WebApr 8, 2024 · The Yorkshire club have hit a good run of form recently, picking up seven points from their last four games, while returning Palace boss Roy Hodgson led the Eagles to a 2-1 win over Leicester last ...
