LED发光字寿命短怎样解决?

所属分类:新闻资讯 发布时间:2021-02-15 来源:买球赛竞猜的app哪个好 浏览量:

在使用LED发光字的时候,有一些LED发光字的发光源有寿命短的情况。那么LED发光字寿命短怎样解决?接下来小编就来为大家介绍相关的解决方法,一起跟着这篇文章来了解一下相关的知识,一起来看看吧。
In the use of LED light-emitting words, there are some LED light-emitting words of the light source has a short life. So how to solve the short life of LED luminous words? Next, let's introduce the relevant solutions. Let's follow this article to understand the relevant knowledge. Let's have a look.
led发光字购买正规厂家生产的合格led单颗灯粒,自己制作模组。切莫在电子市场贪图便宜购买LED单颗灯粒或已制作好的模块。如需购买模块,应看清模块上安装了几颗电阻,安装一颗电阻的模块尽量不要使用。电阻在模块中所起的是限流作用,很容易发热。长时间连续使用,一旦电阻烧坏,这个模组就不亮了。led灯一般不会坏。不要把模组扔掉,只需更换一只相同阻值的电阻即可正常使用。这样可为制作单位节省开支。

LED luminous word to buy qualified LED single lamp grain produced by regular manufacturers, and make their own modules. Don't buy LED single lamp or made module in the electronic market. If you need to buy a module, you should see how many resistors are installed on the module, and the module with one resistor should not be used as far as possible. Resistance in the module is the role of limiting current, it is easy to heat. If it is used continuously for a long time, once the resistance is burnt out, the module will not light up. LED lights generally don't break. Don't throw away the module, just replace a resistor with the same resistance value to use it normally. This will save money for the production unit.
为了减少麻烦、节省开支,选用安装有两颗电阻的模组。另外,对制作模组的供应商的生产设施要有所了解,看其在制作模组时是否采用了防静电设施。如果没有附加防静电设施,在使用中即使电阻没有被烧坏,led灯也很容易被击穿损坏。
In order to reduce trouble and save money, the module with two resistors is selected. In addition, we should know about the production facilities of the suppliers who make the modules to see whether they use anti-static facilities when making the modules. If there is no additional anti-static facilities, even if the resistance is not burned out in use, the LED lamp is easy to be broken down and damaged.
