How to detect the leakage of LED street lamp poles?
You can use a multimeter, remember to clear it first. Cut to the voltage of the gear, and then one end of the ground, one end of the lamp pole (to measure the exposed part of the metal), to see whether the pointer or digital data to the amount to know; there is a volume to the data, there is leakage.
With a multimeter, cut to the voltage of the gear, and one end of the ground, one end is connected with the lamp (to the metal exposed part), and see there is no pointer or digital quantity to know the amount of data; to data leakage is.
LLED street lamp: LED street lamp (Light, Emitting, Diode, light emitting two stage tube), that is, semiconductor lighting. It is a kind of form based on semiconductor pn junction with weak electricity can light efficient solid-state light source, in a positive bias voltage and injection current, injected into the P region of the hole and injected into the N region electron in diffusion into the active region after radiation and emit photons, the electric energy can be directly converted into light energy. It is a solid cold light source. It has the characteristics of environmental protection, pollution-free, less power consumption, high light efficiency, long life and so on. Therefore, LED street lamp will be the best choice for road lighting energy-saving reconstruction.
