What are LEDs?
LEDs, or light–emitting diodes, are semiconductor devices that
produce visible light when an electrical current passed through
them. LEDs are a type of Solid State Lighting (SSL), as are organic
light–emitting diodes (OLEDs) and light–emitting polymers (LEPs).
How is LED lighting different than other light sources, such as
incandescent and CFL?
1. LED lighting differs from incandescent and compact fluorescent
lighting in several ways. When designed well, LED lighting can be
more efficient, durable, versatile and longer lasting.
2. LED lighting products use light emitting diodes to produce light
very efficiently. An electrical current passes through
semiconductor material, which illuminates the tiny light sources we
call LEDs. The heat produced is absorbed into a heat sink.
3. Common LED colors include amber, red, green, and blue. There is
actually no such thing as a “white” LED. To get white light, the
kind we use for lighting our homes and offices, different color
LEDs are mixed or covered with a phosphor material that converts
the color of the light. The phosphor is the yellow material you can
see on some LED products. Colored LEDs are widely used as signal
lights and indicator lights, like the power button on a computer.
