Abstract

The invention discloses an LED (Light Emitting Diode) street lamp device loaded with a lightning arrester. The lightning arrester mainly comprises a U1 voltage dependent resistor, a U2 voltage dependent resistor, a U3 voltage dependent resistor, a U4 voltage dependent resistor, a U5 voltage dependent resistor, a FU1 fuse, a FU2 fuse, a D ceramic gas discharge tube and a PE (Polyethylene) earth wire. When the lightning arrester is subjected to lightning strike or surge voltage, high voltage electricity produced by the lightning strike or the surge voltage is earthed and discharged by the lightning arrester, and the fuse is burned out, so that an LED street lamp constant current source and an LED street lamp are prevented from being damaged.

Description

technical field [0001] The invention relates to the field of street lamps, in particular to an LED street lamp device equipped with a lightning arrester. Background technique [0002] The current LED street lamp constant current source in the prior art uses a current fuse as an overcurrent protection, and there is no lightning protection system at the front end to prevent surges or lightning strikes or surges. LED street lamps are generally installed outdoors and are extremely vulnerable to lightning strikes or surges. damage due to voltage. Contents of the invention [0003] In order to solve the above-mentioned technical problems, an LED street lamp device equipped with a lightning arrester of the present invention is to install a lightning arrester at the front end of the constant current source of the LED street lamp. When receiving a lightning strike or a surge voltage, the lightning arrester will The high-voltage electric ground is discharged, and the constant c...
