Nettet5. aug. 2024 · LED stands for Light Emitting Diode; LEDs are semiconductor devices, just like transistors or other diode types, but with the added ability to convert electricity into light energy. This means that they operate on low DC voltages, and cannot be plugged directly into an AC mains supply like an incandescent light bulb. Nettet21. jul. 2016 · 1) put a diode in series with the LED. This reduces the resistor dissipation by half. 2) use a capacitive-type power supply to drive the LED. You will need a small series resistor to limit the inrush current but the total dissipation can be reduced by at least 90%.

Nettet23. aug. 2024 · LEDs run on a low voltage between 12 – 24 volts for direct current. So, an LED driver will rectify the current even if you’re running on a high voltage between 120 – 277 volts on AC. In short, it helps to step down alternating current to direct current. Or even balance high voltage to low voltage.

When the current flow is in the right direction, the LEDs will only light up when they are in the correct position. At high frequencies, an AC applied to anLED will cause it to blink on and off, and at low frequencies, it will not blink at all.

NettetThe reason for lights dimming is that when the AC starts it consumes very high startup current and it also happens that the lights share some of the wiring with the AC and that wiring has resistance high enough to allow for noticeable voltage drop. I saw a similar issue once many years ago - a fridge motor starting would make the lights dim.
