How do you wire LED lights?

LED lights are a great way to add functional lighting or a bit of flair to a space. They’re also super easy to wire. You can connect an LED strip to an adapter and then plug it in to power it. You can also use a wire splicer to tap your LED lights into an existing and functioning wire to provide power for the lights.

What happens if you wire an LED backwards?

LEDs, being diodes, will only allow current to flow in one direction. And when there’s no current-flow, there’s no light. Luckily, this also means that you can’t break an LED by plugging it in backwards. … A reversed LED can keep an entire circuit from operating properly by blocking current flow.

What is the circuit symbol for an LED?

LED Circuits

The LED symbol is the standard symbol for a diode with the addition of two small arrows denoting emission (of light). Hence the name, light emitting diode (LED). The “A” indicates the anode, or plus (+) connection, and the “C” the cathode, or minus (-) connection.
