LED billboard is to make full use of the characteristics of LED energy saving and environmental protection, and make a colorful signboard. Billboards are also called: LED electronic light box, LED luminous characters, LED waterproof signboard, LED luminous characters, LED external luminous characters, LED tin luminous characters, LED zinc iron luminous characters, LED stainless steel luminous characters, LED titanium luminous characters, LED aluminum luminous characters, LED exposed luminous characters, LED colorful luminous characters, LED light box characters and so on.
1.Tools required for making LED billboards: 30W or 40W soldering iron, soldering tin, electric drill, glue gun, screwdriver, etc.
2. Materials required for LED billboard production: molding iron lettering (preferably purchased locally) to reduce transportation costs, glass glue, resistors (available from our factory), wires (available from our factory), and special power supply for LED signboards (available from our factory).
3. Manufacturing steps of 3.LED billboards:
1. drilling: fix the lettering of purchased molded iron in a proper position, and drill holes with an electric drill: 5MM or 8 mm. The spacing depends on the installation height and manufacturing cost of the external signboard. Generally, the spacing between LED centers is 10-30mm. The smaller the spacing, the better the effect and the higher the cost.
2. Plug in the lights: clean the drilled holes and turn on the lights one by one.
3. Connection: It is difficult to connect in series and then in parallel to the power supply. Don't worry, there are LED strings already made and connected, and each string has reserved terminals. Generally, the red terminal is connected to the positive pole of power supply, and the black terminal is connected to the negative pole of LED special power supply.
4. Test aging: After all LEDs are connected, check the ones that are not bright, and then conduct 24-hour aging test.
5. Glue sealing: Fix the LED on the iron sheet.
6. Retest and install.
