How to make LED flashing light box?

(1)Light box production materials:

Exterior frame: generally made of aluminum alloy profiles.

Light source: light-emitting diode (LED).

Panel: Lv plastic board.

Bracket: generally with wooden bars or aluminum alloy bracket.

Controller: single-channel, 2-channel, 5-channel, 13-channel, etc. (new multi-functional three-in-one) (the role of the controller is to change the 220V AC power

into 220V DC. Coupled with the control itself circuit function to achieve a variety of changes in the effect).

(2) light box common tools: drill (recommended 4.9mm drill), soldering iron, small pliers, glue gun, plexiglass glue.

Tip pliers, soldering iron, multimeter, wallpaper cutter, hook knife, steel straightedge, small scissors, small hammer, plastic welding and so on.

Making steps:

(1) make the required word on the board (usually with a machine sticker) or pattern

(2) use a hand drill or engraving machine to hit the same size as the LED diode straight through the hole.

(3) each word or pattern in the LED lights in series (diode long leg for the positive, short leg for the negative, long leg and short leg screwed together, that is, positive and negative screwed together, with a soldering iron soldered together better. That is, in series), generally a group in series (red no more than 115,

blue no more than 73, green no more than 80), the number of resistors added and the number of LED lights between the relationship between the chart:

(4) between the word and the word or pattern and the pattern of the general parallel connection.

(5) After all the LED lights are connected, generally use a glue gun to fix them to seal. In order to prevent defending and water. Note that all LED two pins must not be shorted.

(6) According to the need to connect the controller to different lines, showing different flashing effects.

The following is the production process

The first step is to choose the material:

Use 2.5mm or 3mm aluminum composite panel as the plate. 2.5mm can only do

Small double-sided light box. Then cut the aluminum composite panel to the size you want. Usually you can use a craftsman's knife with a ruler.

After cutting, you need to tear off the protective film

The second step is to post the word:

Use the engraving machine to carve out the self-adhesive letters you want. The color of the sticker depends on the color of the LED

light you use.

Step 3 Eyeleting:

Eyelet the lettering you have attached. The distance between the lights is 1.5 centimeters. Running edges, then the lights are best to have a larger distance between a few. Generally we run edge will do 2 centimeters or 2.5 centimeters, so as to do out of the running light effect is much better. Running edge of the lamp must be well hit the line. So that the drilling out of the eye is relatively straight. After playing a good eye, we immediately have to light, but in order for us to make convenient, generally we are first drawn on the back of the alignment diagram, draw a good positive and negative poles, so you can save time, wiring is more convenient, will not be wired to look at the last wiring diagram.

The fourth step to install the light:

Installation of the light should be planned first. For example, you the word of that stroke to be connected with that stroke. It's not so troublesome to connect up the wires .

Serial connection: put the LED press + -, + -, ...... + -, + -? Solder the LEDs in series to create a positive terminal (labeled A+) and a negative terminal (labeled K-). The connections of the legs need to be soldered, or they can be screwed together and soldered. Remember: Always solder. Because the leg of the LED is iron silver-plated, there is a current through once the moisture will soon rust, will cause hidden danger to the light box, but also to the after-sales service will bring a lot of trouble. Now a lot of connected lights, with connected lights can save a lot of time to improve production efficiency, but only 20 lights per row, welding is unavoidable.

Insert the light-emitting diodes into the holes one by one. (Note: positive and negative poles to be connected to the end, hand-twisted, there can be no loose places, or use 40W soldering iron welding can be. You have to string all the small segments together. But the total number can not exceed the limit. If it exceeds the limit. You can divide it into 2 or 3 groups, and then we're going to string the resistors.

Note: Because resistors generate heat! So we usually use yellow wax tube cover! In order to achieve insulation and heat insulation!

The fifth step to install the lights:

Specific wiring method, please see the document inside the figure

Every six steps to connect the power:

Connect the power light! Here to pay attention to is to check whether the inside will be short-circuited! Whether there is contact with the aluminum composite panel, because the back of the aluminum composite panel is conductive.
