LED lamp with how to install the LED light strip how to eliminate the fault

Guide: Light strip, is the abbreviation of LED strip, most people say that the noun is too long, so the front LED is omitted, it is called the light strip. LED lights are still common in daily life. Let me introduce you how to install LED lights and how to eliminate LED lights.

How to install the LED light strip:

1. Indoor installation: When the LED light strip is used for interior decoration, it is very simple to install because it does not have to withstand wind and rain. Each LED light strip has a self-adhesive double-sided adhesive on the back. When installing, you can directly remove the sticker on the double-sided adhesive surface, and then fix the LED light strip in the place where you need to install it. As for some places that need a corner or a long length, it is very simple. The LED light strip is a circuit structure consisting of three LEDs in a series-parallel manner. Each of the three LEDs can be cut and used separately.

2, outdoor installation: outdoor installation will be subject to wind and rain, if the use of 3M glue fixed, the time will cause 3M adhesive viscosity to reduce the LED light strip off, so the outdoor installation often uses the card slot fixed way. The place that needs to be cut and connected is the same as the indoor installation, except that it needs to be additionally equipped with waterproof glue to consolidate the waterproof effect of the joint.

3, power connection method: LED light with a general voltage of 12V DC, so you need to use switching power supply, the size of the power supply according to the power of the LED light strip and the length of the connection. If you don't want each LED strip to be controlled by a single power supply, you can purchase a relatively large switching power supply for the total power supply, and then connect all the LED lights with the input power supply in parallel (when the wire size is not enough, you can extend it separately). Uniformly powered by the main switching power supply. The advantage of this is that it can be centrally controlled. The inconvenient place is that the lighting effect and switching control of a single LED strip cannot be achieved. The specific method can be measured by itself.

4, controller connection: LED marquee belt and RGB full-color light strips need to use the controller to achieve the change effect, and the control distance of each controller is not the same, in general, the simple controller control distance is 10 to At 15 meters, the remote controller has a control distance of 15 to 20 meters and a maximum distance of 30 meters. If the LED strip has a long connection distance and the controller cannot control such a long LED strip, then a power amplifier is needed for tapping.

5, pay attention to the connection distance of LED lights: In general, 3528 series of LED lights, the connection distance of up to 20 meters, 5050 series of LED lights, the longest connection distance of 15 meters. If this connection distance is exceeded, the LED strip is prone to heat, which will affect the service life of the LED strip during use. Therefore, the installation must be installed in accordance with the requirements of the manufacturer, should not let the LED lights with overload operation.

How to eliminate the fault of the LED strip:

No reason

1. The packaging protection of the flexible LED strip is imperfect, resulting in damage to the lamp bead during transportation.

2. The soldering point of the flexible LED strip has a phenomenon of virtual soldering, and the vibration during the transportation causes the solder joint to fall off and the light strip is not bright.

3, flexible LED lamp with less solder, the solder joints are easy to fall off

4. The quality of the flexible LED lamp with solder is not good. The soldering point of the LED flexible lamp strip is prone to brittle cracking and falling off during the bending process.

5. When the LED flexible lamp strip is installed, the bending angle is too large, causing the LED flexible lamp to be separated from the copper foil and causing the light to be off.

6. Excessive extrusion of the product when the flexible LED lamp is installed, resulting in damage to the flexible LED lamp with the chip or deformation of the solder joint without falling

7. The flexible LED lamp with the circuit board solder mask is too thick. The solder and the circuit board cannot be completely fused together during soldering, which is also a kind of virtual soldering phenomenon.

8. The flexible LED light strip can not be twisted during installation. If it is twisted, the solder joint of the flexible LED strip will fall off and cause no light.

9, static burning, because the LED is a static sensitive component, there is no static protection measures, it will lead to chip burnout.
