manufacturer:linear description:light emitting diodes leds are manufactured out of a variety of semiconductor materials and are comprised of a p and n type junction, which establishes a voltage potential across the junction. the led provides a light output when the diode is forward biased, causing current to flow through the device. the forward voltage (vf) of the diode will be different for the various materials and colors and ranges from approximately 1.5 v for red to 3.3 v for blue leds. a pulsating led drive circuit can enhance the light output of an led by using a peak current of a much higher level than sustainable under direct drive conditions [1][2]. a high peak current pulse of short duration with a off period between pulses allows time for the leds junction to cool down. high drive currents can result in a degradation of the light output and the life expectancy (time to half light output) of an led. however, the reduction in the life of a pulsed led is minimal if the peak current is below the maximum current limit specified for the device. |
