Static electricity is a pernicious devil, the world countless electrostatic damage to electronic components, resulting in tens of millions of dollars in economic losses. So to prevent electrostatic damage to electronic components, is a very important task of the electronics industry, mains LED lights packaging, application of the enterprise do not take it lightly. Any link problems, will result in damage to the mains LED lights, the LED performance deterioration and even failure. We know that the human body static electricity (ESD) can reach about three kV, enough for the mains LED lights chip to breakdown damage in the LED packaging production line, the grounding resistance of various types of equipment to meet the requirements, it is also important, general requirements for the grounding resistance of 4 ohm, some of the occasions the grounding resistance even to achieve ≤ 2 ohms.
These requirements are for the electronics industry, people familiar with the key is in the actual implementation is in place, whether there is record. Not doing far as I understand private enterprise producing led high bay lights, anti-static measures in place, this is the most finding out grounding resistance test records, even if the ground resistance testing is also a once a year or a few years time, or have a problem check the grounding resistance, not knowing that the grounding resistance test is a very important task, at least four times a year (the test once each quarter), some of the requirements, the monthly for a ground resistance testing.
