Matters needing attention when installing LED modules

Matters needing attention when installing LED modules 1. Special switching power supply for LED. The power supply can only be moisture-proof, not waterproof, so waterproof measures must be taken when the power supply is installed externally. 2. The output voltage of the switching power supply is adjusted according to the characteristics of the LED module. Please do not rotate the voltage adjustment button arbitrarily during use.

3. The LED modules all use low-voltage input, and the power supply is required to be installed within 10 meters of the LED light-emitting module. 4. LEDs are divided into positive and negative poles. When installing, pay attention to the positive and negative poles of the power port wiring. If the positive and negative poles are reversed, the module will not emit light and will not damage the LED module. Just change the connection and it will be normal. 5. The LED module adopts low-voltage input, so it must not be directly connected to 220V without going through the power supply, otherwise the whole module will be burned.

6. When installing the LED module, it is required to use double-sided tape or woodworking glue to make the module slot and the plastic bottom plate firmly adhered. When using double-sided tape, it is necessary to add glass glue, otherwise the module will fall off under the outdoor sunlight for a long time. 7. When installing modules in blister characters or boxes, use three-point and four-point lines as much as possible. When connecting lines, try to make the entire word or box form a loop, or multiple loops, that is, use red and black power supplies The lines connect the modules at the end of each stroke according to the positive and negative poles.

8. The number of series-connected groups of outlet modules at the power port should not exceed 50 groups, otherwise the brightness of the tail modules will decrease due to voltage attenuation. Although forming a loop can avoid attenuation, it should not connect too many modules. 9. For LED modules that have not been waterproofed, when they are installed in fonts or cabinets, rainwater should be prevented from entering the fonts or cabinets.

10. The distance between modules can be adjusted according to the brightness requirements, and it is best to control the distribution of points per square meter between 50 and 100 groups. 11. When the power cord is connected to the cabinet, it must first be connected to the corresponding four or three groups of modules through a four-point line or three-point line. After the power cord enters the box, a larger knot should be tied to prevent it from being torn off by force from the outside.

12. The length of the single branch line is 12~m and 15~m respectively, according to the actual use. The raised connecting wires (including unused connecting wire ends) should be fixed on the blister base with glass glue to prevent shading. 13. Do not push, squeeze or press the components on the module during installation, so as not to cause damage to the components and affect the overall effect.

14. In order to prevent the connecting wire from falling off the wire holder easily, the wire holder is designed with a barb. If it is inconvenient to insert, it should be withdrawn and reinserted. It must be confirmed that the connecting wire is firmly plugged in, otherwise it will cause it to fall off in the future.
