What is LED Lighting? Most everyone is familiar with Light Emitting Diode (LED's) from their use as indicator lights in numeric displays on consumer electronic devices and message boards. With improvements in LED materials and production, brighter, more efficient and more colorful LED's are now available which have moved the technology to a wide range of lighting applications.
How does a LED light work? LED's are solid state semiconductor devices that convert electronic energy directly into light. LED?s produce ?cold? light which is very energy efficient because most of the energy used radiates in the visible spectrum. Incandescent and fluorescent lamps radiate energy in the non visible spectrum creating heat as well as light.
What color bulbs can be produced? There are three colored bulbs (Red, Green and Blue) that are typically used in LED lighting applications. It is possible to create the entire color spectrum (64 billion colors) to include white light with these three colored bulbs.
How can three colored bulbs make 64 billion colors? Color mixing is achieved by varying the voltage to each of the red, green and blue bulbs. The controller for the color mixing may be either an external unit or may be combined on the lighting unit itself.
How can LED Lighting be used? LED lighting can produce up to 64 billion different colors that can be used to wash walls light display cases or highlight architectural fixtures.
How much energy is used compared to standard lighting? LED lighting uses 90% less energy than a standard light bulb.
How long do LED light bulbs last? LED bulbs have a life for 100,000 hours (11.4 years). When is the last time you had a light bulb stay lit for 11 years straight?
