Luminous character is an electronic product. Waterproof measures should be taken for outdoor luminous signs. We often encounter the failure of luminous signboards due to the lack of rain proof measures. Therefore, we must inform the manufacturer where to use them and what waterproof measures are adopted for luminous signboards. The following is a brief introduction for you:
1、 Reserved water leakage hole of word shell
When cutting the bottom plate of the character shell, cut a small gap under the bottom plate, which is called water leakage hole. It is specially used for outdoor production to avoid the water entering into the luminous characters. When the water seeps into the shell, the built-in LED light source will be damaged.
2、 Use waterproof LED light source
After the leakage hole is treated, we should pay attention to whether the LED light source used in the shell is waterproof. The LED light source is also divided into two types, waterproof and waterproof.
3、 The top of the sign with luminous door head is rainproof
After the rainproof measures are taken for the light-emitting words, if they are used for the signboards at the door heads, the baffle plates can also be installed on the signboards at the door heads, so as to avoid the rainwater directly falling on the luminous words.
