LED Light Box Lights Do Not Have Any Other Way To Repair?

LED Light Box lights do not have any other way to repair?
LED Light Box light does not light Maintenance: If not bright, with a multimeter DC 250V file, black pen then green line, red pen then red line, if the instructions beating or 200-220V, indicating that the controller is normal; black pen does not move, Followed by measuring the voltage at each end of each led, if a LED two feet voltage difference is very large or no voltage, indicating that the LED damage, try again after the replacement.

LED Light Box assembly: I introduced a kind of inexpensive way, although the aluminum is beautiful but the higher cost I did not use. Material: 2 * .mm wood keel and 2. * mm aluminum angle (90 °), these materials are generally decorated in the market. Note: often have new customers to ask why green and blue light is easy to bad, in fact, most of the reasons is not the quality of the lamp problems, LED Light Box but the novice welding technology is not fully grasp, welding is not smooth, too long and cause LED lights are damaged, which need to improve the welding technology and speed to avoid the. There is the reason for static electricity, green and blue lights are afraid of static electricity, our body and soldering iron are static, so need to bring anti-static wrist (I are free to the customer's), the conditions can be used anti-static soldering iron. And then there is the quality of the purchase of LED Light Box too many reasons. All the purchase of LED Light Box accessories, need to choose large manufacturers of goods, choose partners to choose a good reputation seller.
Recently the emergence of LED Light Box flashing the problem? How should we be able to solve? In series connection: the LED Light Box by + -, + -, ... ... + -, + - series welding, resulting in a positive (as a mark A +) and a negative (for a mark K-). The connection of the lamp leg requires soldering with tin, or it can be screwed together and then welded. Do remember: be sure to weld. Because the LED legs are iron-plated, there is current through the damp once will soon rust, will give the light box caused by hidden dangers, but also to the aftermarket brought no small trouble. Now a lot of Siamese lights, with Siamese lights can save a lot of time to improve production efficiency, but each row has only 20 lights, welding can not be avoided. The long pin of the LED is "+" (positive) pole, LED Light Box and the short pin is "-" (negative) pole. Use acrylic plate, plastic plate, or other insulating material, I use black 2.5mm double aluminum plate when the majority. Will be the first word to do with the single-sided adhesive paper, affixed to the size of the aluminum-plastic plate, with a drill or engraving machine hit the hole (spacing according to the size of the word, the general distance of 10-15mm a), the size of the hole Diameter 5mm can not be too big. F5 spotlight to do the word is the best hole to be greater than 15mm, because we try to know. If the use of 546 oval lamp, the hole can be controlled between 20-10mm, the closer the effect the better.
LED Light Box production methods have no other way? Grouping (string): in accordance with the table is not greater than the color of the light-emitting diodes can be connected in series the maximum number of strings, such as each string of red LED should not be more than 120. The reason is very simple, LED Light Box the controller output is about 210V DC, red light is about 2V working voltage, that is, after each LED will be a step 2V, if the number of LEDs too much, then the controller output voltage can not reach the light When the voltage required for normal operation, the string will not light, or the brightness is too low. It is not recommended to add "*" in the table. When the number of LEDs in series is close to or exceeds the number of "*", it is easy to cause the circuit to be unstable, and it should be divided into two strings or more A group.
LED Light Box production: the use of acrylic board, plastic plate, or other insulating materials, I use black 2.5mm double aluminum plate when the majority. Will be the first word to do with the single-sided adhesive paper, affixed to the size of the aluminum-plastic plate, with a drill or engraving machine hit the hole (spacing according to the size of the word, the general distance of 10-15mm a), LED Light Box the size of the hole Diameter 5mm can not be too big.
