| LED (Light Emitting Diode) lighting isn't new. It
has been around for decades, but in recent times, the technology has
grown by leaps and bounds, not only in brightness, but in control and
integration.
LED lighting fixtures work on the basis of additive color mixing. Each
fixture is comprised of three primary colored LED's: red, green, and blue. With
this combination of colors and the integration of the theatrical standard of
control, DMX512, there is a possibility of producing approximately 16.7 million
colors, or 16 bit color. The virtually endless color combinations lends
itself to some spectacular colors and effects. When a series of fixtures is
connected, a chasing rainbow can be created, or custom color chases and scrolls.
With certain LED fixtures, even video can be displayed.
One great benefit to LED lighting, is that they draw very small amounts of
power, thus alleviating the need for huge power supplies that would be required
for conventional lighting like PAR can's. Another great benefit is that (our)
LED's do not emit infrared or ultraviolet light waves and therefore do not
generate any heat. Conventional lighting fixtures like PAR cans produce heat and
cause whoever is on stage or in close proximity to the lights to have to deal
with the hotter temperatures and all of its affects. Another advantage of the
LED's ability to remain at room temperature is that fixtures are always cool to
the touch. If for some reason fixtures are placed discretely on the floor, there
is no risk to children or bystanders who may come into contact with an otherwise
hot lighting fixture.
