AUTOMOTIVE LED-Constant-current

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.
