  • A brief tutorial on Romex® (Type NM-B) wiring.



    Dimming common offroad car/truck/ATV LED lights. PWM control of input power to lights.
    Offroad LED lights are very common for supplimental lighting. However, they maybe blinding for the incoming vehicle driver and lack brightness control. Since the LED lights have built-in LED drivers, varying the input voltage will not vary the light output. PWM control of the input power will change the output brightness, but it may not be the best solution.

    CH1: Output power +/- at LED light, DC 5.0V/div, top trace. 0.5ms/div. Trace to ground is LED on (GND-CH switching).
    CH2: Input power +/- at dimmer, AC 0.50V/div, bottom trace.
    Load: LED lights (9-30Vin), 23W (small, 13.8V 1.65A), 47W (large, 13.8V, 3.4A).
    PWM dimmer: N-CH MOSFET, 620Hz LED dimmer. 5′ input and 5′ output power cable.
    Battery: 12V lead-acid.
    Power supply. 30V 3A adjustable.

    Testing:
    Test 1: 23W LED light with battery. PWM dimming functional. Some induced switching voltage spikes at IN/OUT power cables.
    Test 2: 23W LED light with power supply. PWM dimming functional. Some induced switching voltage spikes at IN/OUT power cables. 620Hz audible switching noise.
    Test 3: 47W LED light with battery. PWM dimming functional. High induced switching voltage spikes at IN/OUT power cables (up to Vin p-p). Induced switching noise may cause interferrence with electronic equipment. PWM switching audible.
    Test 4: 47W LED light with power supply. PWM dimming functional. High induced switching voltage spikes at IN/OUT power cables (up to Vin p-p). PWM switching noise easily audible.

    Recommendation: Use PWM dimming for up to 50W LED power. Add extra capacitors for filtering. Greater than 50W not recommended. High switching noise. Large capacitor/inductor/diode filters required.
