Last week, a customer brought a light bar and said that this LED waterproof light bar is only 4.5 yuan. He immediately put it in the water and turned it on for me to show. I took a closer look, no, this is not a waterproof light bar, this is just an ordinary light bar. Light strips, ordinary light strips can also emit light when placed in water, but I don’t know that ordinary 12V/24V low-voltage LED light strips can also be lit in water, but this is not called waterproof LED light strips. There is no change, but over time, the oxidation of the circuit board and the lamp bead pins will affect the use effect and life of the LED light bar, and it will also cause a short circuit in the line, causing unpredictable danger. At present, the waterproof technology of waterproof LED light strips can be mainly divided into the following four types:

1. LED light bar IP65 waterproof: commonly known as surface drop glue waterproof light bar, currently it is made of epoxy resin glue and PU glue. Put the LED light strip flat on the glue-dipping table, fix the LED light strip with double-sided tape on the back, and then drop a layer of glue on the surface of the LED light strip to make the surface waterproof

2. LED light bar IP66 waterproof: usually also called hollow full casing waterproof light bar, the general casing is silicone full casing and PVC full casing.

3. LED light bar IP67 waterproof: usually also called half casing dripping waterproof or half casing glue waterproofing, that is, the bottom is covered with half casing, and then do glue or glue treatment. Waterproofing with glue will affect the heat dissipation of the light bar, and long-term use will cause the sealant to fall off.

4. LED light bar IP68 waterproof: usually called full casing glue-filling waterproof or full casing glue-pumping waterproof, it is the highest waterproof level of LED light bar at present, and can be used completely in water.

The above are the characteristics of waterproof LED strips. If you need more detailed information on waterproof LED strips, please consult Shenzhen SUNLITE Optoelectronics Co., Ltd.
