LED home lighting because of its energy saving, stability and other characteristics by everyone's favorite, today, LED home lighting manufacturers on the stability of the special for everyone to do a summary:
The brightness of the LED varies with the magnitude of the current, and the voltage of the LED is slightly different from the current curve, so that the brightness of the LED illumination is often unstable with the change of the voltage of the power supply. To maintain brightness consistency, a constant current driver with LEDs is needed. The constant current driver makes the LED work in a fixed current mode, so the brightness stability is high. The constant current driver also allows the LEDs to operate at a constant current for long periods of time.
