ABOUT LEDs
LED Basics
An LED (Light Emitting Diode) is a semi conductor that produces photons of light when energized by an electrical current. LEDs are made up of
two semi-conductor layers, one positive and one negative, and is known as the P-N Junction. Where these two layers meet is called the “Depletion
Region”. When current is applied to the LED electrons flow across the depletion region causing it to emit photons. (Figure A)
Surface mounted high power LED’s are constructed of five main components, the diode or semiconductor (1), reflector cup (2), lens (3), heat sink
slug (4), and the anode and cathode leads (5). The heat sink slug while integral to the LED is designed to protrude from the bottom to ensure positive
contact with a larger heat sink designed to accommodate the total number of LED’s in the luminaire and conduct the heat away from the LED’s.
(Figure B)
LEDs are powered or driven by an electronic driver. The LED driver is used to convert the input AC line voltage to a lower DC voltage while producing
a constant DC current on the output. The amount of current at the output is critical as it affects both the light output and the junction temperature of
the LEDs. A constant current is also important as a fluctuating current will cause inconsistent light output.

Lifetime (Hours)
The three main design elements critical to the performance and useful life of LED’s
are junction temperature, drive current, and proper heat sinking. All three of these
elements must be considered from the design stage through the installation of the
luminaire to prevent adverse effects on system performance. When the junction
temperature of an LED reaches its maximum, the result can be lower light output
along with a color shift towards the higher end of the spectrum. A 30% to 50%
decrease in its useful life can be realized for every 10ºC increase in temperature.
For example, an LED being driven by 500mA of current operating in an ambient
environment of 25°C (77°F) producing a junction temperature of 85°C (185°F)
should realize a life expectancy of 60,000 hours. (See Fig. C) If the same LED
was exposed to an ambient environment of 35°C (95°F) The result would be an
increase in the junction temperature to 95°C (203°F) and the life expectancy would
be reduced to 40,000 hours.
Basically, as temperature increases in an LED system whether it is caused by
increased drive currents or higher ambient temperatures, the result is decreased
efficiency (less lumens per watt), a shortened useful life, or both.
