What materials do led electronic light boxes need?
Brief introduction of led electronic light box
The light body of Led electronic light box is generally made of aluminum-plastic plate, light-emitting diode and colloid. , light emitting diode as light source, aluminum alloy profile frame.
Second, the led electronic light box production materials:
1. outer frame: aluminum alloy profiles are generally used, depending on the area. There are four corners. Thickness: 2cm width: 2cm border material thickness:1.2mm.
2. Panel: aluminum-plastic board or PVC color board, acrylic, iron sheet. Whole size: 1.2m * 2.4m ... black.
3. Light source: light emitting diode (connected with foot lamp), appearance shape: upper ellipse and lower circle. Passing current: 20 mA. Large angle: 120 degrees. The color will depend on the requirements of the light box.
4. Bracket: Aluminum alloy bracket is generally used. Used to fix the light box.
5. Controller: one-way, two-way, five-way, etc. Connect directly to 220V v v.
6. There are two kinds of connecting wires: (1) with a length of 15cm. (2) The line length is 10cm. Thread area: 0. 16 square. Full coil: multiple colors. Thread area: 0. 16 square. Multi-strand Material: UL 1007 model.
7. Rectifier bridge: 2A
8. Power cord: 220V plug wire.
9. Resistance:1/2w, depending on the number of lamp beads.
Three, led electronic light box production materials tools:
Flashlight, 4.9mm drill, multimeter, light box resistance adapter, screw screwdriver, needle-nosed pliers, glue gun glue stick, electric soldering iron.
4. Manufacturing steps of 4.led electronic light box
A tutorial on making led electronic light boxes 1. Typesetting in CorelDRAW software,
Arrange the size and distance of the content, and arrange a circle with a diameter of 4.9 mm at the position where holes need to be punched in the future. Tutorial on making led electronic light box II. The sorted CorelDRAW files are exported as PLT files, and then imported into Wen Tai carving software, and the graphics are carved with a carving machine. Post-it notes are generally used as carving materials, and reflective films are recommended. Reflective film has better texture effect, but the price and cost are higher.
The third course of making led electronic light box. Remove the carved contents except the characters and stick the characters on the aluminum-plastic board. Generally, a black 3mm aluminum-plastic board is used as an electronic light box.
Course 4 of led electronic light box making. Punch holes according to the position of the circle arranged in the first step. Note: The diameters of LED lamps are 5mm and 3mm, and it is best to use 4.9mm and 2.9 drills when drilling holes.
Tutorial on making led electronic light box 5. Insert the lamp and pay attention to the positive and negative poles of the lamp. After the lights are plugged in, use LED electronic light box tester to test whether all the plugged lights are on, and then use glue stick or three-second glue to fix all the small lights on the aluminum-plastic board, which also plays a waterproof role.
Led electronic light box making course VI. Wiring, connect all the small LED lights in series, and then use the LED electronic light box to test each resistance, and remember that each current should be controlled between 13- 18 mA.
Too much current is easy to burn out, and too little current is insufficient brightness of LED lamp. The seventh course of making led electronic light box. Connect the controller and make the connection according to the circuit instructions on the controller. Connect 220V AC to test for about 5 minutes. Disconnect the alternating current and gently touch the resistor with your hand. If the resistance is hot, it means that the current in this circuit is relatively large, and you need to increase the resistance.
The eighth course of making led electronic light box. Packaging. Make sure all the above steps are ok. Spray the lamp feet of electronic lamps with self-spray paint. This step is to prevent short circuit and waterproof effect between lamps. After the paint is dry, wrap the front and rear boards with the special edge of F-shaped light box.
