Understanding LED Drivers - 1000Bulbs.com
www.1000bulbs.comConstant-Voltage Drivers Constant-voltage drivers power LEDs that require a fixed output voltage with a maximum output current. In these LEDs, the current is already regulated, either by simple resistors or an internal constant-current driver, within the LED module. These LEDs require one stable voltage, usually 12V DC or 24V DC.

engineering.purdue.eduobserver due to higher average forward current being supplied to the LED. For maximum brightness, a constant current (i.e., the duty ratio of the current pulse is one) will be supplied to the LED. The advantage of this method over the AM diming is the absence of spectral slide and uniform dimming over different LED strings.
Electronic Control Transmission (ECT)
autoshop101.comfour terminals: VC, VTA, IDL and E. A constant 5 volts is applied to terminal VC from the engine ECU. As the contact point slides along the resistor with throttle opening, voltage is applied to the VTA terminal. This voltage increases linearly from 0 volts at closed throttle to 5 volts at wide-open throttle.
