Many people may have such doubts at work. That is to use a buried IP lamp with a nominal IP67 when doing a lot of projects. It is confirmed that there are also test reports that are IP67. Many of them are international brands, but still There will be water leaks.
Then the IP67 buried light will leak water?
To understand the cause of the leak, you must first understand what IP67 stands for.
I don't know what IP67 means. Students can check: "Landscape lighting | The type of underwater light and application details" "iPhone 7 is IP67, what does IPXX mean?" Click on the topic to read, understand the IP of the fixture waterproof level.
The reasons for the leakage of the buried lamp are summarized as follows:
1 design is not reasonable
2 material defects
3 process defects
4 reasons for installation
1. Unreasonable design
For example, some of the lamps are filled with glue. When the lamps are shipped from the factory, the waterproof level is really no problem, and there will be no water leakage.
However, in an outdoor environment, it will start to age and turn yellow after about half a year, and the lamps will enter the water.
Therefore, the waterproofing of the glue is not reliable, and the waterproof structure is the king.
Teacher Xu said: "Because the unreasonable design of the product is not qualified, it should not exist."
Some of the lamp covers are not pressed, and the manufacturer does not press a few more points. It is important to know that buried lights are often in an environment that is eroded by water, and it is easy to leak water if the cover is not pressed properly.
There are only 3 screws in such a large luminaire. The distance between the screws is very far. Do you think it is pressed tightly?
Such a lamp cover is not pressed, and it will definitely be tilted up.
