Sometimes LED light-emitting words in the use of the process may not light, at this time do not rush, as long as the correct method to find out the cause and timely correction can be, most of them are because the circuit or poor contact and other problems are not difficult to solve, but some detailed problems involved in the inspection still need to be noted. Specifically, the following aspects should be paid attention to when the LED luminous word is not bright.
1、 Attention should be paid to the use of gloves by professionals
When checking the LED light-emitting words, professional personnel are required to carry out disassembly and assembly, and the staff are required to wear gloves. When disassembling the plastic light-emitting words, they must wear pure cotton white operating gloves. Because there are oil, salt, acid, alkali and other ingredients in hand sweat, they are corrosive. If they are not carefully adhered to the stainless steel, the surface of the stainless steel will slowly corrode, which will cause the stainless steel surface to fade and change color, resulting in the loss of original beauty. Therefore, gloves should be worn for isolation.
2、 Handle with care
Due to the LED light-emitting words are generally more, so we need to pay attention to the angle of holding and pay attention to operate with a gentle way. Special attention should be paid to the disassembly and assembly of the outer frame of the plastic LED light-emitting words. It is forbidden to collide and twist. The outer frame should be placed flat on the ground. Then close the lower part of the luminous character and fix it with the hexagon screw.
3、 Pay attention to safety
LED light-emitting words manufacturers to pay attention to the safety of the circuit, check the need to cut off the power supply, unplug, and disconnect the power supply, it is worth reminding here is to prohibit the leakage protector as a power switch, and then check the original electrical appliances. The manufacturer of LED light-emitting words also reminds us to be careful in the inspection, such as the power line into the hole, the output terminal, the wire on the lamp holder, etc., and all the inspection process should pay attention to the prohibition of live operation.
The above are several aspects that need to be paid attention to when checking the LED light-emitting words. In addition, we should also pay attention to check whether the power line on the upper part of the blister light-emitting word is in the power access slot. If there is no need to make correction, plug in the power plug and close the main power switch to see whether the lighting is normal. If there is a phenomenon that one side is on and the other side is not on, the well-known LED luminous word manufacturers suggest that the power supply should be cut off, the plug should be pulled out and the lamp holder wires and tubes should be checked to see if they are not in place; whether the ballast input and output wires are loose.
