Lighting is driven by a power Cheap LED lights and heat sink three -part
by Yang X. The foreign trade Lighting is driven by a power Cheap LED lights and heat sink three -part. Pressure test generally test-driven power input and the human body can come into contact pressure between the lamp housing values. Pressure achieved by insulation.
If the negative than the positive high voltage, the power transformer secondary winding and rectifier conduction, a voltage is forced to a positive voltage leveled, such a condition does not cause over crushed New T5 Counter LED Tubes, and if a positive voltage higher than the negative voltage, then there is current ( this current is different from the leakage current ) flows through the LED, which is in the pressure test, the LED will flash causes.
This article discusses the use of isolated power T8 LED assembled in the pressure during the test cheap led tube lights beads damaged main reasons: Measures are: 1. Selected voltage high drive power; 2 copper aluminum plate as large as possible, and the positive than the negative greatly; 3 good control of aluminum foil on the minimum creep age distance : 2.5KV of not less than 2.5MM. 4. Did not miss any one weak link, such as the input line (preferably with pressure above 5KV wire ) , aluminum plate exposed metal parts of the plug and socket point glue.
