고휘도 LED

LEDs (light emitting diodes) are light sources based on semiconductor devices. LEDs are used for a broad range of applications, such as backlight illumination of mobile phones or displays, traffic signals with low maintenance, car head lamps and rear lights, head-up displays, projectors and general illumination. They offer a number of advantages compared to other light sources, including long lifetime, low total life cycle costs, compact size, easy implementation into end devices, and particularly, very high efficiency. The use of LEDs for illumination can save up to 85 % in energy consumption compared to standard light sources, offering the potential to reduce about 15 % of the total worldwide energy consumption if all standard light sources were substituted.
