How to Wire LED Lights in a Circuit

Many people do not know how to wire LED lights due to the accuracy required in the circuit values and the number of LEDs to use in a lighting circuit. For the circuit to work, you need to use accurate values for voltage, current, and resistance. It is quite difficulty to wire them due to the delicate parts involved. However, with the correct guidelines, anyone interested can succeed in wiring them. This is because the calculation of the values is straightforward. Here, are four steps that may help you in wiring LED lights.

STEP #1: Acquire the right LEDs

The first thing one needs to do in order to wire LED lights in a circuit is acquire the number of LEDs you require in your circuit. Most of the LEDs available in the market require just a little amount of power. Therefore, if you have a high power supply, you can wire as many LED lights as you want. You must be aware of the spec of the LEDs to use in your circuit. You must be aware of the voltage and current of the LEDs. To make the work easier, use LEDs with the same value of voltage and amperage.

STEP #2: Decide the type of circuit

You may decide to wire LED lights in series or parallel. It is advisable to decide which type to use in your circuit before you start wiring. However, your decision may be dependent on the power supply you have. If you have a high power supply, you may connect the LEDs in series. This is because in this type of connection, the required voltage is more than the sum of all the voltage of the LEDs you are using. Conversely, if you have a weak power supply, wiring in parallel is the best option, but in case you want to wire a few LEDs, a series connection is appropriate due to its simplicity.

STEP #3: Determine the resistor you need

The next step, when you want to wire LED lights in a circuit, is the determination of the resistors you require in the circuit. This is pretty easy because there are online LED circuit calculators you can use. You just need to go online and input the number of LEDs in your circuit, the voltage of your power supply, and the amperage and voltage of each LED. The calculator will provide the current of the resistor you require so that your circuit can work.

STEP #4: Wiring the resistor into the circuit

After determining the correct resistor, you need to wire it into the circuit. You may do this in two ways. One, you can use a resistor with current rating of the total circuit and fix it to the positive terminal of your power supply. Two, you can use a resistor with the same value, but with a lower current rating to the cathode of each LED. The cathode of each LED should be wired in parallel while the anodes should be wires to an SPST switch. Then make sure you have wired the other terminals of the switch to the negative terminal of your power supply. That way, you have managed to wire LED lights in circuit. If you have been wondering how you can wire LED lights in a circuit, here are simple steps that may guide you.
