The city of Wenzhou will use luminous fonts to decorate when carrying out lighting projects. In Wenzhou, the use of led luminous characters is frequent, but the led lights are still relatively short in the service life, because many luminous fonts have not been used for a year, the LED module needs to be frequently replaced, which will bring more trouble and economic losses to users and advertising manufacturers.

The suggestion on the short service life of the above LED is that customers should remember not to buy a single LED lamp particle or a module that has been made in the electronic market. If it is to purchase the module, you need to see how many resistors are installed on the module, because it is not necessary to use the module with only one resistor, because the resistance plays a role in the module is to limit the flow rate, and it is easy to produce heat. If it is used continuously for a long time, once the resistance is burned out, the module will not be bright.
