What are the connection modes of constant voltage LED strips?

Indoor installation: When LED light strips are used for indoor decoration, the installation is very simple because they do not have to withstand wind and rain. Take the LED light bar produced by LEDER Lighting as an example, each LED light bar is pasted with self-adhesive 3M double-sided adhesive on the back. When installing, you can directly tear off the sticker on the surface of the 3M double-sided adhesive, and then fix the light bar on the place that needs to be installed. place, just press it flat with your hands.

As for some places that need corners or are too long, what should I do? Very simple, the LED light bar is a circuit structure composed of 3 LEDs in series and parallel, and each 3 LEDs can be cut and used separately.

Outdoor installation: Outdoor installation will be exposed to wind and rain. If 3M glue is used to fix it, the 3M adhesive will decrease over time and cause the LED strip to fall off. Therefore, outdoor installation often uses card slots to fix it. Where cutting and connection are required, the method is the same as indoor installation, except that waterproof glue is required to strengthen the waterproof effect of the connection point.

Power supply connection method: The general voltage of the LED light strip is DC 5V/12V and 24V, so a switching power supply is required for power supply. The size of the power supply is determined according to the power and connection length of the LED light strip. If you don’t want to use one power supply to control each LED light strip, you can buy a switching power supply with relatively high power as the total power supply, and then connect all the LED light strip input power supplies in parallel (if the wire size is not enough, you can extend it additionally), Unified power supply by the general switching power supply. The advantage of this is that it can be controlled centrally. The inconvenience is that the lighting effect and switch control of a single LED light bar cannot be realized. Which method to use can be measured by yourself.

Controller connection method: LED marquee strips and RGB full-color light strips need to use a controller to achieve changing effects, and the control distance of each controller is different. Generally speaking, the control distance of a simple controller is 10 to 15 meters , The control distance of the remote controller is 15 to 20 meters, and the longest distance can be controlled to 30 meters. If the connection distance of the LED light strip is long, and the controller cannot control such a long light strip, then a power amplifier is required for branching.

Pay attention to the connection distance of the LED light strip: Generally speaking, the longest connection distance of the 3528 series LED light strip is 20 meters, and the longest connection distance of the 5050 series LED light strip is 15 meters. If the connection distance is exceeded, the LED light strip will easily heat up, which will affect the service life of the LED light strip during use. Therefore, when installing, it must be installed according to the manufacturer's requirements, and the LED strip should not be overloaded.

Connection method for LED light strips longer than 5 meters: Due to the voltage drop of LED low-voltage light strips, and the maximum power of the controller can only drive LED light strips with limited power, so after a full load of the controller, it must be followed. Synchronous amplifier with controller The above is the connection diagram, which can be operated according to the above connection method.

The connection method of 5-meter LED strips is generally a roll of low-voltage LED strips every five meters because it can be driven by a controller.
