LED发光字是时下广告市场很火热的广告制作,因为用户居多,各种故障就很多,例如灯不亮,发光字不亮就有很多原因,当然对应的也就有很多维修方式。下面我们具体看下LED冲孔发光字不亮造成的原因有哪些?
LED light-emitting words are very popular in the advertising market nowadays. Because of the majority of users, there are many kinds of faults. For example, if the light is not on, there are many reasons for the light-emitting words not on. Of course, there are many maintenance methods. Let's take a look at the specific led punching light-emitting words do not light what are the reasons?
一、亮下一闪就全灭了:原因是变压器故障,把LED灯烧坏掉了。
1、 When it was on, it all went out: the reason was that the transformer failed and the LED lamp was burnt out.
二、灯全部不亮:这种原因不好找,线路不通,变压器坏掉,检查下线路与变压器。或是有虚焊。
2、 Lights are not on: this reason is not easy to find, the line is blocked, the transformer is broken, check the line and transformer. Or there is faulty welding.
三、有的亮,有的不亮:这是LED灯的原因。因为LED模组虽然是串线,但其电原因是并联。这就防止某个灯坏掉,影响全部灯的亮度。把灯换掉,就解决掉了。
3、 Some are on, some are not: This is the reason for LED lights. Although the LED module is in series, its electrical reason is parallel connection. This prevents one lamp from breaking down and affecting the brightness of all lights. Change the light and it's done.

那么,如何实施检查步骤呢?
So, how to implement the inspection steps?
1. 检查发光字的时候,需要专门的人员进行拆装,要求工作人员佩戴手套,拆装吸塑发光字时操作人员必须戴纯棉白色作业手套。因手汗中有油、盐、酸、碱等成份,均有腐蚀性,粘在不锈钢上会慢慢腐蚀不锈钢表面,使不锈钢表面慢慢退旧变色,失去原有的美观。
1. When checking the light-emitting words, special personnel are required to carry out disassembly and assembly, and the staff are required to wear gloves. When disassembling the plastic light-emitting words, the operators must wear pure cotton white operating gloves. Because there are oil, salt, acid, alkali and other components in hand sweat, they are corrosive. If they are stuck on the stainless steel, they will slowly corrode the stainless steel surface, so that the stainless steel surface will slowly fade and change color, and lose the original beauty.
2. 轻拿轻放,发光字一般比较的多,需要注意拿的角度,以及注意要轻男轻放,拆装吸塑发光字外框时一定要平拿轻放,禁止碰撞及扭曲,把外框平放在地面上。轻拿、平起、平挂,然后再把发光字下部合上,用内六角螺钉固定 。
2. Handle with care. Generally, there are many luminous characters. It is necessary to pay attention to the angle of holding, and pay attention to the gentle handling of men. When disassembling the outer frame of the blister luminous character, be sure to handle it flat. Do not collide or twist it. Put the frame flat on the ground. Then close the lower part of the luminous character and fix it with the hexagon screw.
3. 注意安全,线路的安全,检查的时候需要切断电源,拔下插头,断开电源(禁止将漏电保护器当作电源开关使用),再进行电器原件的检查(禁止带电操作);在检查时要求细致,如电源线进入孔、镇流器输入、输出接线柱、灯座上的电线等等
3. Pay attention to safety and the safety of the circuit. During the inspection, it is necessary to cut off the power supply, pull out the plug, disconnect the power supply (it is forbidden to use the leakage protector as the power switch), and then conduct the inspection of the electrical components (live operation is prohibited). During the inspection, it is required to be careful, such as the inlet hole of the power line, the input and output terminals of the ballast, the wires on the lamp holder, etc
4. 查看吸塑发光字上部电源线是否在电源经出入槽内,如没有须做更正,插上电源插头,合上总电源开关看灯光是否正常,如有一边亮一边不亮的现象,请先断开电源拔下插头,并检查灯座电线,灯管是否松动不到位;镇流器输入、输出电线是否松动等。
4. Check whether the power line on the upper part of the blister light-emitting character 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 one side is on and the other side is not on, please first disconnect the power supply, pull off the plug, and check whether the lamp holder wire is loose or not in place; whether the ballast input and output wires are loose, etc.
