How do LED strip light connectors work?

Led strip connector is composed of a connector cover, a connector seat plate, two limit bars, and several metal sheets. The end of the metal sheets is fixed on the connector seat plate. By sliding the light strip into the open end of the metal sheet, and close the cover to fix the light strip, and the limit bars are inserted into the seat plate. We know that metal has very good conductivity, and the working principle of the led connector is to conduct electricity from one light strip to another through the metal sheet.

When the LED chip of your led strip light is damaged, cut out the damaged LED light chip, and connect the led light strip with led connectors. 


What are the different kinds of LED connectors? What connectors do you need for LED strip lights?

There are many kinds of led connectors in market, including strip-to-strip, strip-to-wire, and wire-to-wire connectors.

Strip-to-strip led light connectors

We mentioned briefly what kind of connector should be used for different led strip lights in the article How to know what your led strip light is.

2-pin led connectors are for single color led strip lights. There are two copper pads on the circuit board, one is the positive and the other is negative. And the two copper pads are the connection points of the strip light. This is the origin of the name of 2-pin. If your led strip light is white, red, blue, green, or other single color, please look for 2-pin led strip connectors.

What is CRI(color rendering index)?

3-pin led strip connectors are for tunable white led strip lights and single signal addressable led strips.

Tunable white led strip lights are also known as dual white led strips or CCT light strips, which have two different white color, warm white and daylight color. You can decide which color to use in different scenes. And they have three copper pads, one positive and two negatives for warm white and daylight lines.

Single signal addressable led strips are three copper pads as well. But one for positive, one for negative, and one for digital signal line. Although tunable white led strip lights and single signal addressable led strips are all 3-pin, the effect of their use is different.

4-pin strip connectors are for RGB color changing led strip lights, dual signal addressable LED strip lights and breakpoint resume addressable LED.

RGB strips are the most familiar led light strips for people. We often see people asking question how to connect RGB led strips. RGB color changing has four copper pads, one positive and R, G, B color lines which are the negative.

Dual signal addressable strip lights and breakpoint resume addressable are four copper pads too. And one for positive, one for negative, one for clock line, and one digital signal line.

Note that addressable RGB led strip lights do not necessarily use 4-pin connectors. When selecting led connectors for addressable light strips, the basis for selection is not to have several connection points, but to look at its signal line.

5-pin light strip connectors are for RGBW led strip lights, which have five copper pads. One positive line, and four negative lines for R, G, B, W color.

6-pin led strip light connectors are for RGBCCT led strips. The copper pads are six, one for positive as the same, and others for R, G, B, W, WW color lines. You can understand that an RGBCCT led strip light is equivalent to RGB light strip plus tunable white led strip.

There are other shape connectors for whom want to change the direction of the led strip light.

Strip-to-wire led strip connectors

The use of a strip to wire connector is like the strip-to-strip connectors. However, the strip-to-wire connector only uses one head to connect led strip light, and the other end is a wire. It is suitable for connecting light strips to power supply or led controller.

Wire-to-wire led connectors

During the installation process, you will encounter a situation where you need to connect two wires. At this time, it is obviously impossible to use strip to strip connectors. Since what needs to be connected is a wire and a wire, so when we choose the connector, we should choose a wire-to-wire connector. You can also use a nut cap to connect it. Strip the insulation layer of a section of wire, use a tool to wind the bare wires together, and then tighten them with a nut cap. But you should pay attention to that the positive pole needs to be connected to the positive pole, and the negative pole is the same when connecting polarity. This is a wrong way to connect the positive pole to the negative pole.

If you tend to connect one power supply to multiple led light strips, and you think the wiring is troublesome, you can try the cable splitter. And the light strips are connected in parallel. So the current of all the light strips can not exceed the maximum current carrying capacity of the cable splitter.
