LED Facts
October 27, 2009
Light Emitting Diode, more commonly known as "LED", represents the cutting edge
of lighting technology. LEDs operate on a totally different concept than traditional
incandescent style lights. Instead of using a brittle metal filament that is susceptible
to shock and vibration, LEDs are solid-state devices with no moving parts utilizing
an electronic chip that is encapsulated in an epoxy substrate. This design provides
increased durability and a protective seal against outside or foreign elements.
EFFICIENCY - LEDs are very energy efficient and consume less power
(amp draw)...up to 90% less power than incandescent bulbs. This reduces the load
on your electrical system including your battery, alternator, and power converter
resulting in direct money-saving benefits.
NO HEAT - LED lights generate no heat therefore they are cool to
the touch and can be left on for hours without incident or consequence if touched.
LONGEVITY - LEDs are rated for 100,000 hours compared to 3,000
hours for incandescent bulbs. Consider real world circumstances where most incandescent
bulbs need to be replaced within one year. An LED light will last over 20 years
before needing replacement.
FUSING - Due to the low energy draw of LEDs, the gauge of wire
used can be reduced. CAUTION: Typical incandescent fusing requirements are too robust
for LEDs and therefore, fusing must be sized for the low LED circuit draw. Incorrect
fuse sizing can cause damage to your electrical system. Carolina LEDs Electronic
Engineering Staff can assist you when sizing your fuse requirements.
FUTURE - LEDs are vastly becoming the preferred low voltage lighting
resource versus incandescent lighting. New and brighter LEDs are under development
and will impact your future lighting requirements.
