The
stability of LED illumination The brightness of light-emitting diode
with the current size of the different, and the manufactured
light-emitting diode, its voltage and current curves slightly
different, so the brightness of LED lighting often changes with the
supply voltage can not be stabilized. In order to maintain the same
brightness stability and the need to light-emitting diode constant
drive to achieve. Constant-current driver can make light-emitting
diodes work in the fixed current mode, and thus the stability of high
brightness. Constant-current drivers are also to light-emitting diodes
in a certain current, long-term work to maintain a longer life
expectancy.
