Brightest
white LED in market: Analysis of brightness, V & I characteristics
of HB LEDs
Voltage and current characteristics of high brightness
white LED.
High Bright (HB) white LEDs offer significant advantages
of space saving, power saving, and long life over CFTs and
other filament lights. However the LED light output is very
sensitive to the input voltage and current. This demands
highly regulated voltage and current to be fed to white
LED to derive optimal light output from white LEDs. White
LEDs released in year 2008 have significant improvement
in light output and other electrical characteristics. Here
in this short article the behavior of latest white LED for
varying voltage and current are analyzed and you have a
choice to choose the brightest LED. At these very initial
stages of white LED innovation, power designer has to be
wiser in selecting right component.
The forward voltage, Forward Current, and Max Light output
are compared and analyzed in this below table. Its kind
of reference selection guide for LED lamp/lighting design.
