Eight things you did not know about LED

This article is part of the Energy.gov series highlighting the “Top Things You Didn’t Know About…” Be sure to check back for more entries soon. 8. A light-emitting diode, or LED, is a type of solid-state lighting that uses a semiconductor to convert electricity into light. Today’s LED bulbs can be six-seven times more energy efficient than conventional incandescent lights and cut energy use by more than 80 percent. 7. Good-quality LED bulbs can have a useful life of 25,000 hours [...]

LED Basics

LED Basics Source: https://energy.gov/eere/ssl/led-basics Unlike incandescent lamps, LEDs are not inherently white light sources. Instead, LEDs emit nearly monochromatic light, making them highly efficient for colored light applications such as traffic lights and exit signs. However, to be used as a general light source, white light is needed. White light can be achieved with LEDs in three ways: Phosphor conversion, in which a phosphor is used on or near the LED to convert the colored light to white light RGB systems, in [...]
