Lutron LED Features

Lutron LED Features

LED lighting systems (luminaires) operate a lot like fluorescent lighting systems in that they need compatible controls, drivers and light sources. This combination of elements should be designed to work together and should be thoroughly tested.

LED Basics
An LED is a semiconductor device that produces light when an electric current flows through it, and can be manufactured in a variety of color temperatures.
White LEDs do not exist, but an LED can provide white light in one of two ways:

  • Utilizing a blue or near ultraviolet LED with a phosphor coating
  • Combining RGB (Red, Green, Blue) LEDs and calibrating them to the correct white color temperature

For general illumination purposes LEDs are then grouped onto an LED array (also called an LED light engine). This array combines multiple LED chips into one complete light source that is equivalent to a lamp.

  • The LED array can be exclusively LEDs, LEDs with a few regulating components, or LEDs with an entire driver on the array
  • LED arrays are then integrated into a fixture or an LEDi lamp (with a screw in Edison base).

Lastly, LEDs DO produce heat! They do not radiate their heat like incandescents do, but the heat needs to be removed from the LEDs through a heatsink to avoid failure.

LED Applications

LED Applications: Downlights, Undercabinet, Cove and Outdoor Illumination

LEDs are emerging as a viable light source for general illumination and are excelling in many applications, including:

  • Downlights
  • Under Cabinet Lights
  • Cove Lights
  • Decorative Lights
  • Outdoor Lights

LEDs excel in these particular applications because they can easily rival incandescent and CFL light sources, as shown below:

The graph demonstrates the lifetime of an LED array in comparison to CFLs, Halogen, and incandescent lights. LEDs not only have longer lifetimes, but their light output remains bright as the other two sources fade. (source: DOE)
