Fix the purchased molding iron sheet characters to the appropriate position, and drill holes with electric drill: 5mm or 8mm. The spacing depends on the installation height and production cost of the external signboard system. Generally, the center spacing of LED is 10-30mm. The smaller the spacing, the better the effect and the higher the cost.
2. Plug in light:
Clean up the drilled holes and place the lights one by one.
Led billboards are connected in series and then connected in parallel to the power supply and LCD advertising machine. This step is relatively difficult. Each string has a reserved wire end. Generally, the red wire end is connected to the positive pole of the power supply, and the black wire end is connected to the negative pole of the led special power supply.
4. Test aging:
After connecting all the LEDs, check and deal with the ones that are not on, and then carry out the aging test for 24 hours.
5. Sealing glue:
Fix the led to the iron sheet.
6. After the second test, the LED billboard can be installed.
