2. The customer's pattern needs to be carved and pasted on the aluminum-plastic board in the art department. It's more economical to use empty words next time.
3. According to the font and size of the characters, the distance of punching holes in the center of the characters with a pen is 1.5-2cm. Run around the lamp distance of 3cm and master it flexibly. The denser the lights, the better the effect. Can also be made into hollow characters, the effect is better. (Pay attention to the crossing distance when ordering)
4. punch holes with a flashlight or engraving machine, and then clean the burrs.
5. Install the lamp according to the mode (+,-) (+,-) for future connection. Make sure the light is in the proper position.
6. After installation, apply half glue on one side of the lamp bead to facilitate connection. The picture below shows the connection of running lights. The lamp corners can be fixed together, but they should be firm, and it is best to finish welding.
7. The LED lights of each word or pattern are connected in series, and the red color of each loop shall not exceed 1 15, the blue color shall not exceed 73, and the green color shall not exceed 80. When the number of characters or patterns exceeds the number used, an extra loop is added.
8. Word-to-word or pattern-to-pattern parallelism.
9, in the production process must do a good job of anti-static.
10, note that all LED pins must not be short-circuited.
1 1. Measure the current of each loop to ensure that the current is 15-20mA.
12. Select the number of resistors according to the number of patterned lamp beads, put the upper lead of resistance welding into a yellow wax tube and connect it in series between any two LEDs in the loop.
13, Led welding time can't exceed 3 seconds. (It is best to use a constant temperature soldering iron with grounding wire)
14. Connect the controller and watch the production effect. The light box shows that the assembly is completed after normal packaging with glue sticks.
15, the three-in-one (five-way) controller outputs DC 220v, red is the positive electrode, the positive electrode lead of the lamp bead is connected with red, the negative electrode lead of the light box is connected with yellow, and three green wires are the negative electrodes running all over the floor, one for each color. White is usually a bright negative electrode.
16, punch 1-2 8mm water leakage holes at the lower end of the light box frame. According to the size of the light box, drill holes on the edge of the aluminum-plastic plate on one side of the aluminum material, and fix the aluminum-plastic plate with screws to prevent the panel from being deformed.
17. Before installation, a 48-hour aging test should be conducted (the light box should be lit for 48 hours) to check the reliability of the light box.
18, the long angle of a single led is positive, and the short leg is negative. Even-pin leds look at the chip inside the lamp bead, the big one is the negative electrode, and the small one is the positive electrode, compared with a single LED.
19. Please refer to the table in the controller picture for the number of lamp bead resistance ratios.
20. The controller outputs 220v DC, so we must pay attention to safety in the production process. Do not operate when power is on.
2 1. When making the light box, put the painted aluminum-plastic plate into the frame and drill vertically in the form of bench drill.
