NettetThe University of Leeds is a redbrick university in the city of Leeds, West Yorkshire. Officially founded in the early 20th century, the university’s origins can be traced back to the 19th century, when the Yorkshire College of Science was established. It was one of the first colleges in the UK for students of all faiths and backgrounds, set up to … A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor. White light is obtained by using multiple semiconductors or a layer of light-emitting phosphor on the semiconductor devi…
NettetFor over 400,000 years, humans have only had one method of generating light. Through the burning of organic materials, heat and light were generated. Over the course of the last century, we have learned that passing an electrical current through a resistor, a device that resists the passage of an electric current, also generates heat and light.
