When it comes to light boxes, I think everyone will not feel strange. Indeed, a light box refers to a kind of light that shines with lights and has a certain decorative effect on the periphery, so that when people see it, it has a warning effect or a decorative beautification effect. Now, many businesses will set up some light boxes in their own shops to attract customers. So, how is the light box made? You may not know much about this knowledge, so Xiaobian will introduce you to the method of making light boxes for your reference when necessary.
installation method
(1) The size of the aluminum-plastic board is 122×244, and the size is calculated and used reasonably, so don't waste it. Cut the appropriate size with wallpaper knife, and send the patterns that customers need to the art department to be carved and pasted on the aluminum-plastic board with instant stickers. I have carved hollow characters and used instant spray paint, which is better than post-it notes. Post-it notes fade after a year in the sun. It is more economical to use hollow characters next time.
(2) According to the font and size of the characters, the distance of punching holes in the center of the characters with a pen, the distance between pattern lights is 1.5-2cm, and the distance between running lights is 3cm. You should master it flexibly, and the denser it is, the better the effect will be. It can also be made into hollow characters for better effect. (pay attention to the crossing distance when ordering)
(3) punch holes with a flashlight or a engraving machine, and clean the burrs after finishing.
(4) install the lamp according to the pattern (+,-) (+,-) for later connection. Make sure the lights are in place.
(5) After installation, glue half of the lamp bead for connection. The picture below shows the connection of the running light. The lamp corners can be fixed together, but they should be firm, and it is best to finish soldering.
(6) The LED lights in each word or pattern are connected in series, with no more than 115 in red, no more than 73 in blue and no more than 81 in green in each loop. When the number of characters or patterns exceeds the number used, an additional loop is added.
(7) parallel connection between words or patterns.
(8) anti-static work must be done well in the production process.
(9) note that all the pins of the LED must not be short-circuited.
(11) Measure the current of each loop to ensure that the current is 1.5-21 mA.
(11) Select the number of resistors according to the number of patterned lamp beads, and put the upper lead of resistance welding into a yellow wax tube and string it between any two LEDs in the loop.
(12) The welding time of LED should not exceed 3 seconds. (It is best to use a constant temperature soldering iron with a grounding wire)
(13) Connect the controller and watch the production effect. The light box shows that the assembly is completed after it is normally encapsulated with a glue stick.
(14) The three-in-one (five-way) controller outputs DC 221v, and red is positive. Connect the positive lead of the lamp bead to red, the negative lead of the light box to yellow, and the three green lines are the running negative poles, one for each color. White is a normally bright negative electrode.
(15) Make 1-2 8mm leaking holes at the lower end of the light box frame. Drill holes on the edge of the aluminum-plastic plate on the side of aluminum material according to the size of the light box and fix the aluminum-plastic plate with screws to prevent the panel from deforming. This is the frame eye under the light box, two of which are waterproof eyes and the other two are connected with the fixing bracket. This is the screw used to fix the aluminum-plastic plate on the side frame eye of the light box to prevent the deformation of the frame and the corner, and to fix the side of the frame.
Precautions
Before installation, a 48-hour aging test (let the light box run for 48 hours) should be conducted to test the reliability of the light box.
the long angle of a single LED is the positive pole, and the short leg is the negative pole. Even-legged LED looks at the chip inside the lamp bead, the big one is the negative electrode, and the small one is the positive electrode, which is compared with the single LED.
refer to the table in the picture of Taobao controller for the number of lamp bead resistance ratios (click to enlarge and watch).
It's convenient to purchase and contact after collecting the store. There are light box kits with different prices in the store for you to make. I recommend you to buy a kit with an aluminum frame. (The aluminum material has been cut for easy assembly)
The controller outputs 221v DC, so be sure to pay attention to safety in the manufacturing process. Do not operate when power is on.
when making a light box, install the painted aluminum-plastic board into the frame and drill holes vertically in the form of a bench drill.
through the above description, xiaobian has introduced some methods of making light boxes for you, from which you can refer more, so as to have a certain basis when you need to set up light boxes. Xiaobian here would like to remind everyone that because light boxes are generally directly connected with 221 volts of high-voltage electricity, we must pay attention to safety when carrying out a series of operations on light boxes, so as to prevent accidents and ensure safety is a constant theme in our life and work!
