Led power circuit
Nettet4. jan. 2024 · An LED driver is an electronic circuit specially designed to drive or illuminate a set of LEDs safely through controlled current and voltage output, as per the specifications of the LEDs. Since LEDs are vulnerable semiconductors devices, they must be driven using a regulated current and voltage power supply. NettetMULTI-LED CIRCUITS. If several LEDs need to be driven from a single power source, this can be done by wiring all LEDs in series, as shown in Figure 10, provided that the supply voltage is significantly greater than the sum of the individual LED forward voltages. FIGURE 10. LEDs wired in series and driven via a single current-limiting resistor.
