In the electric strength test for general illuminative appliances, electric arc or light beads failure is common. The author studied the structure of general LED illuminative appliances, and provided a security level for the creepage distance between the interior live parts and the exterior. From analyzing the design of a bypass safety capacitor on the LED substrate surface, the author found an effective solution to mitigate electric arc or light beads failure in the electric strength test, which extends the light span of LED illuminative appliances and conforms to the safety regulations.
