12vled light box billboard

With perforated iron characters, coupled with LED lights and controllers, you can achieve effects such as scanning, gradient, jump, and flowing water.

Here we first introduce the ordinary exposed LED lighting. How to make characters.

1. Tools required for making LED exposed luminous characters (signboard): 30W or 40W electric soldering iron, argon arc welding machine, needle nose pliers, scissors, wire strippers, jigsaw, electric drill , glue gun, screwdriver, etc., almost the same as making an electronic light box. Of course, the method is also similar.

2. Materials required for making LED exposed luminous characters (signboards): Iron plates are generally made of 08 or 1.0 concrete Depending on the size of the characters and the customer's requirements, LED lights (including light strings and light groups, single colors and seven colors, etc.), glass glue, strips, resistors, wires, solder, and special LED power supplies

3. Exposed LEDs Steps for making luminous characters (signboards):

1. Forming of metal characters:

① Saw the outline of the characters on the iron sheet. Of course, you need to write a character mold first and fix it to For the appropriate position, you can use iron sheet shears for thin iron sheets. If you want it to be nice or thick, use an engraving machine. There are also plasma cutting, laser cutting, wire cutting, etc. Use an electric drill to drill holes: 5MM or 9mm. Colorful lamps are generally 12MM. It can also be punched directly with punching equipment, which is convenient and fast. There are also punched boards for sale on the market. The spacing depends on the height of the exterior signboard production and installation and the production cost. Generally, the LED center spacing is: 10--30 mm. The smaller the spacing, the better the effect, and the higher the cost.

② Surround the back of the drilled hole with an iron sheet edge strip and weld it firmly. If the iron sheet is not thick, it is an argon arc welder. For thicker ones, you can use an electric welder directly. This depends on the individual level.

③ For polishing and baking treatment, spray painting is generally used more now.

Of course, if you don’t know how to do calligraphy at first, or you think it’s troublesome, just leave it to a professional calligrapher. You can also install the lights yourself.

2. Put three Or multiple LED lamp beads are welded in series with resistors and wires, and the resistors are added. The method of adding resistors is the same as that of making a light box, so I won’t go into that here. Made into LED light strings. And reserve enough wiring at the positive and negative terminals of each string. Someone asked whether the lamps used directly as light boxes can be used in series. Theoretically, it is possible, but it is not practical. First, the iron sheet is conductive and cannot be insulated. Second, it is best for such lamps to be separated, which requires a large angle. .It will be beautiful when you make it.

3. Insert the lights: Insert the lights one by one into the drilled iron holes. Note that the positive and negative wiring of each string of lights should be kept as close as possible to facilitate connection to the power supply.

4. Wiring: Weld the positive wiring of each string of lights in parallel with a long red wire, and weld the negative wiring in parallel with a long black wire. Connect the red wire to the positive pole of the LED-specific 5V or 12V power supply, and the black wire to the negative pole of the LED-specific 5V or 12V power supply (the positive and negative poles cannot be reversed).

5. Use sealant to fix the LED to the iron sheet.

6. Test aging: After connecting, turn on the power. Check if the handle is not bright, and then perform an aging test for 24 to 48 hours.

7. OK, ready for delivery

You will find that it is similar to making a light box, but this method is still more troublesome. Nowadays, most of them use ready-made lights. It is convenient and fast to install the lights directly on the string or light group, and it is also easy to maintain.

You will find that the lighting angle of this light is much wider, and it can be seen from the front and side, but it is also Choose according to specific circumstances
