How to Light an LED on High Voltage

Light Emitting Diode (LED) lighting is usually known as low voltage energy efficient, and is widely used world over because of its ability to consume less voltage. You can however also light an LED on high voltage.

LED lights have become commercial in the past few years because of the variety of colours they come in and the brightness they provide. If you want to light an LED on high voltage, then it is important that you should have proper knowledge of working with electricity equipments and the processes involved.

    First of all, you need to purchase high quality LEDs before you start lighting them on high voltage. You cannot use common LEDs on high voltage, as they cannot survive input from high voltage electricity.

    You can visit a nearby electrical store and ask for high voltage LED lights. Before purchasing LEDs, you can tell the storekeeper about the level of voltage you plan to work on, as this will help him provide you with suitable LEDs.

    Arrange LEDs in two arrays. The first array will be forward biased, and the other will be reverse biased. The forward biased array will be lighted when AC cycle will be in its positive half, and the negative half of the AC cycle will light the reverse biased array.

    Set the energise and the dе-energise cycle of the two LЕD arrays in such a way that it matches the cycle of the high voltage current. In order to get proper lighting results, the Alternating Current (AC) cycle is really crucial.

    Use redundant connections to wire receptacles, as this will prevent the wire from short circuit, or else, you may end up burning out the entire array. Try using a heavy gauge wire, which allows the high voltage to pass easily.

    If you use light gauge wire, then the arrays are most likely to heat up right after you connect them with the power source.

    Now you can test the circuits by connecting the high voltage AC power unit. If there is any bad connection, fix it and then turn on the electricity.
