What is an LED driver?
|
Regardless of type, size, or power, all LEDs work best when driven with a constant current source since LED colour changes with small variations in driving current. LEDs often support varying system voltages and forward voltages, which can cause variations in LED brightness and colour. An LED driver is a self-contained power supply that has outputs matched to the electrical characteristics of your LED or array of LEDs. There are currently no industry standards (as of 2009), so understanding the electrical characteristics of your LED or array is critical in selecting or designing a driver circuit. Drivers should be current-regulated (deliver a consistent current over a range of load voltages). Drivers may also offer dimming by means of pulse width modulation (PWM) circuits. Drivers may have more than one channel for separate control of different LEDs or arrays. |
