Embodiment Construction

[0011] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation of the protection scope of the present invention.

[0012] Such as figure 1 with figure 2 Shown: an LED street lamp device equipped with a lightning arrester is a commercial AC power supply that transmits power to the lightning arrester 10. The lightning arrester 10 is arranged at the front end of the LED street lamp constant current source 11, which is after the input AC power is rectified Output low-voltage DC power to the LED street lamp 12 to illuminate the LED street lamp 12. The lightning arrester 9 is mainly composed of U1 varistor 1, U2 varistor 2, U3 varistor 3, U4 varistor 4, U5 varistor 5, FU1 fuse wire 6, FU2 fuse wire 7, D ceramic gas discharge tube 8, PE grounding wire 9, the varistor 1 and U2 varistor...

Abstract

The invention discloses a light-emitting diode (LED) road lamp device additionally provided with a lightning arrester. The lightning arrester is mainly composed of 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, an FU1 fuse wire, an FU2 fuse wire, a D ceramic gas discharge tube and a (poly ethylene) PE ground connection wire. When the LED road lamp device is shocked by lightning stroke or surge voltage, the lightning arrester can enable high voltage generated by the lightning stroke or the surge voltage to be connected with the ground to be discharged, the fuse wires are burned out, and the an LED road lamp constant current source and the LED road 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 existing LED street lamp constant current source uses a current fuse as overcurrent protection, and there is no lightning protection system at its front end to prevent surges or lightning strikes or surges. LED street lamps are generally installed outdoors and are extremely vulnerable to lightning or surges. Voltage damage. Summary of the invention [0003] In order to solve the above technical problems, a lightning arrester-equipped LED street lamp device 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 it is struck by lightning or surge voltage, the lightning arrester will cause the lightning strike or surge voltage. High voltage electric grounding discharge, LED street lamp constant current source and ...
