浅析LED树脂发光字变暗的因素!

相信大家已经觉察到了当我们使用一段时间的树脂发光字之后,会发现有些发光字的字体会变暗,那么树脂放光字字体变暗的因素有哪些呢,我们来分析一下。
I believe you have noticed that when we use resin luminous characters for a period of time, we will find that some luminous characters will darken. So what are the factors that make resin luminous characters darken? Let's analyze them.
1、变压器短路,变压器短路是造成发光字变暗的一个原因,造成供电不足。需检查变压器找出漏电部分才能解决。
1. Transformer short-circuit, transformer short-circuit is one of the reasons for the luminous word darkening, resulting in insufficient power supply. Need to check the transformer to find out the leakage part to solve.
2、模组灯电线破裂造成电线短路。
2. The module lamp wire is broken, causing a short circuit.
3、变压器与灯珠电压不匹配,需更换相匹配的变压器。
3. The voltage of transformer and lamp bead does not match, so the matching transformer needs to be replaced.
4、电源与灯珠W数不成比,过小,造成供电不足,一般后期出现这种情况的主要是看是不是有搭配多个电源,有其中的电源损坏,造成供电不足。
4. The power supply is not in proportion to the w number of lamp beads, which is too small, resulting in insufficient power supply. Generally, the main reason for this situation in the later stage is whether there are multiple power supplies, and the power supply is damaged, resulting in insufficient power supply.
5、灯珠光衰,有些商家在制作时一味追求低价,提高自已价格竟争力,而采用一些低价,劣质不合格的灯珠模组,更有不法商家采用回收的LED蕊片模组,其灯珠往往采用加大电流方式使其具有与合格灯珠相等的亮度,但住住其光衰衰退讯速,一般在使用寿命在半年左右。
5. Some manufacturers blindly pursue low price to improve their price competitiveness, and use some low price, inferior and unqualified lamp bead modules. Some illegal manufacturers use recycled led core module. The lamp bead often increases the current to make it have the same brightness as the standard lamp bead. However, the service life of the lamp bead is generally less than half a year about.

6、树脂AB胶的耐黄变质量不合格,当然只要没有问题的树脂胶有点黄变也影响不大,如果黄变严重,立即换胶水。
6. The anti yellowing quality of resin AB glue is not up to standard. Of course, as long as there is no problem of resin glue yellowing, it has little effect. If the yellowing is serious, change the glue immediately.
其实导致LED产品光衰的原因很多,关键的还是热的问题,尽管很多厂商在次级产品不特别注重散热的问题,但这些次级LED产品长期使用下,光衰程度会比有注重散热的LED产品要高。LED芯片本身的热阻、银胶的影响、基板的散热效果,以及胶体和金线方面也都与光衰有关系。
In fact, there are many reasons leading to LED product light decay, the key is the heat problem. Although many manufacturers do not pay special attention to heat dissipation in secondary products, the light decay degree of these secondary LED products will be higher than that of LED products that pay attention to heat dissipation under long-term use. The thermal resistance of LED chip itself, the influence of silver glue, the heat dissipation effect of substrate, colloid and gold wire are also related to light decay.
具体原因还是要大家具体分析才可以,这样才能更好的对号入座从根本上解决问题,更多关于发光字的资讯可持续关注我们官网,或者随时与我们联系。
The specific reasons still need to be analyzed, so that we can better take the seat according to the number, fundamentally solve the problem, pay more attention to our official website, or contact us at any time.
