Led Tv Repair
An LED is a semiconductor device that emits visible light when an electric current passes through it. The light is not particularly bright, but in most LEDs it is monochromatic, occurring at a single wavelength. In comparison with fluorescent lights, LEDs have significantly lower power requirements and convert power to light more efficiently so that less is lost as heat and focus it more precisely so that there is less light leakage, which can cause fuzziness. An LED also lasts much longer than most other lighting technologies.
