LED light box repair
Specifically, you can use the electronic watchs Ohm file to be positive and negative to the tube of the lamp. If the lights are not turned on, it means that this lamp is damaged and replace a new one.If the lamp beads are not bad, you can use an electronic meter to continue to see if it is a series of resistance or line.If there is no problem with all the above components, it is very likely that the LED control chip is caused by the damage of the chip. You can replace a chip to repair the LED light box.If you use these methods, you cannot restore your LED light box, then Xiaobian recommends that you go to professional maintenance shops for maintenance.
LED light box power
1. This method is to estimate the power by estimating the current.Assuming that each string of LED lamp beads is calculated at a standard of 20mA, the power consumption of each string of LED lamp beads is about 220V*0.02A = 4.4W2. This method is to estimate the power of the LED light box based on the number of pearls per string.First of all, the number of each string of LED lamp beads (if the number of work is large can be calculated at the average number), and then calculate the power of different colors of lamp beads, and finally add.For example, assuming that the power consumption of white and blue beads is basically equal, that is, the power consumption of each lamp bead is about 3V*0.02A = 0.06W; and the power consumption of red, green and yellow beads is basically equal, each lamp each lamp, each lampPearl power consumption is about 1.7V*0.02A = 0.035W, and then multiplied by the total number of lamp beads.

Two types of connection lines: (1) Line 15cm length.(2) Line length 10cm.The area of ??the line: 0.16 square meter of the line: multiple colors, the area of ??the line: 0.16 square meters, multi -shares, the material is: UL1007 model 7. Rect bridge: 2A8.One -half watt depends on the number of lamp beads.
LED light box price
This LED electronic light box is fine to make one by itself. Like this to make an advertising company a double -sided, it costs at least 350 yuan, and it will not exceed 180 yuan by yourself.
