How to Wire LED Strip Lights (Wiring Diagram Included)

LED strip lights are popular because they're energy-efficient, long-lasting, and flexible. You can use them for decoration, lighting up a workspace, or setting a mood in your home. They're easy to install and can be cut to fit exactly where you need them. In this article, there are detailed guides about the various types of LED strip lights, like single color, tunable white, RGB, RGBW, RGB & CCT, and addressable LED strip lights.

To reach the great wiring work, firstly, we should learn three key factors linked with LED strip lights, parallel connection, voltage drop and PWM amplifier.

Understanding Parallel Connection: Simplified

When we talk about a parallel connection, imagine several paths laid out side by side. Electricity flows through these paths simultaneously. It's like having multiple roads in a city; cars (electricity) can choose different roads but reach the same destination. In a parallel circuit, if one path is blocked, electricity flows through the others. This setup keeps devices running smoothly even if one fails.

Please do NOT connect multiple strips in series to a power supply, controller, or amplifier.

Voltage Drop: A Simple Explanation

Think of voltage drop as a reduction in power as electricity travels along a wire. It's like when you're trying to water a garden with a long hose; the water pressure (voltage) decreases the further it has to travel. This happens in electrical circuits too. Over long distances, the energy supplied at the beginning of a wire isn't the same at the end. Understanding this helps in designing circuits that work efficiently.

PWM Amplifier: Turning Complex to Simple

A PWM (Pulse Width Modulation) amplifier controls the power to devices. Imagine turning a light switch on and off very fast. The light seems dimmer the faster you flick the switch. This is what a PWM amplifier does; it quickly turns the power on and off to control how much energy reaches a device. The longer the switch is on compared to off, the brighter the light.

A PWM amplifier takes small power signals and makes them stronger while keeping the on-off pattern the same. It's like using a megaphone to amplify your voice; the megaphone doesn't change what you say, it just makes it louder. This is useful in many electronics to control power efficiently without wasting too much energy.

Types of LED strip lights

LED strip lights are long, flexible lights that you can stick almost anywhere to add color or light. There are several types, each with its own special features.

1. Single Color LED Strips: These are the simplest type, shining in one color. They're perfect for creating a mood or highlighting areas in a room.
2. Tunable White LED Strip Lights: These lights let you change the shade of white, from a warm yellow to a cool blue. It's like adjusting the sunlight through a window during the day.
3. RGB LED Strips: RGB stands for Red, Green, Blue. These strips can mix these three colors to create a rainbow of colors. They're great for parties or when you want to change colors often.
4. RGBW LED Strips: These are like RGB strips but with an extra white LED. This means they can produce pure white light or colored light, making them more versatile for lighting a space.
5. RGB & CCT LED Strip Lights: RGB & CCT stands for Red, Green, Blue, and Correlated Color Temperature. These strips combine the color-changing abilities of RGB LEDs with the white light temperature control of CCT LEDs. You can pick any color or set the white light's warmth or coolness.
6. Addressable LED Strips: Each LED on these strips can show a different color at the same time. This allows for complex lighting effects, like animations or color waves. It's like having a bunch of tiny lights you can control individually to create patterns or designs.

How to Wire Single Color LED Strip Lights

Wiring single-color LED strip lights is straightforward. Begin by identifying the positive (+) and negative (-) terminals on both the LED strip and your power source, which could be a non-dimmable or dimmable LED driver. Connect the positive terminal of the LED strip to the positive output of the driver, and do the same with the negative terminals. Use a connector or solder the wires directly for a more secure connection.

Wiring Single Color LED Strip Lights with Non-Dimmable LED Drivers

Non-dimmable LED drivers supply a constant voltage. Simply connect the driver to your LED strip by matching the positive and negative wires. Ensure your LED driver's output voltage matches the voltage requirement of your LED strip.

Wiring Single Color LED Strip Lights with Dimmable LED Drivers

Dimmable LED drivers allow you to adjust the brightness of the LED strip. The wiring is similar to that of non-dimmable drivers but with the addition of a dimmer between the power source and the LED driver. Ensure compatibility between all components.

0-10V Dimmable LED Driver Connection Diagram

For a 0-10V system, you'll wire the positive and negative power wires directly to the LED strip and the dimming wires to a compatible 0-10V dimmer. This system allows for smooth dimming from 0% to 100% brightness.

How to wire addressable LED strip lights

Wiring addressable LED strip lights lets you control each LED individually. First, identify the data, ground, and power wires on your strip. Connect the power wire to your power source, and the ground wire to both the power source and your controller. Finally, connect the data wire to the controller's data output. Make sure to use a controller compatible with your strip's protocol, like WS2812B or APA102. Follow the strip's arrow direction for correct data flow. Secure connections with soldering or connectors for reliability. This setup allows you to create dynamic, colorful lighting effects programmable through your controller.

How to Wire SPI Addressable LED Strip Lights

SPI (Serial Peripheral Interface) addressable strips allow for individual LED control. Connect the data (and clock if required) lines to an SPI-compatible controller, with separate power connections to the strip.

SPI Addressable LED Strip Lights with Data Channel Only

Connect the data line from the controller to the data input on the strip, along with power connections, for basic addressable control.

SPI Addressable LED Strip Lights with Data and Clock Channels

For strips requiring a clock signal, connect both the data and clock lines from the controller to the strip, ensuring synchronized LED control.

SPI Addressable LED Strip Lights with Data and Backup Data Channels

Some strips offer a backup data channel for redundancy. Wire both primary and backup data lines for increased reliability in dynamic LED installations.

How to Wire DMX512 Addressable LED Strip Lights

To wire DMX512 addressable LED strip lights, start by connecting the strip's DMX input to a DMX controller's output. Use a DMX decoder if your strip isn't directly compatible. Link the power wires from the strip to your power supply, ensuring the voltage matches. Ground the strip and controller together. Set the DMX address on the decoder or strip to define where its control starts in your DMX chain. This setup allows you to control the LEDs' color and pattern through the DMX console, enabling precise and complex lighting scenes.

DMX512 addressable strips integrate into DMX systems. Use a DMX to SPI decoder if necessary, connecting DMX in/out to control individual LEDs via DMX commands.
