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
The present invention relates to the street lamp field, relate in particular to a kind of LED road lamp device that installs lightning arrester additional.
Background technology
The LED street lamp constant-current source of prior art adopts the current insurance silk as overcurrent protection, at its front end lightning protection system is not set, is used for preventing surge or thunderbolt or surge, and the LED street lamp generally is installed in outdoor, very easily is struck by lightning or surge voltage and damaging.
Summary of the invention
For solving the problems of the technologies described above, a kind of LED road lamp device that installs lightning arrester additional of the present invention, namely at LED street lamp constant-current source front end one lightning arrester is set, be struck by lightning or during surge voltage, the high-tension electricity ground connection discharge that lightning arrester will be struck by lightning or surge voltage produces, LED street lamp constant-current source and LED street lamp exempt from damage.
In order to achieve the above object, technical scheme of the present invention is:
A kind of LED road lamp device that installs lightning arrester additional of the present invention, this device is to transmit electricity to lightning arrester in the mains ac power supply, lightning arrester is arranged on the front end of LED street lamp constant-current source, described LED street lamp constant-current source is for the LED street lighting with the backward LED street lamp output of the AC rectification of input low-voltage DC, described lightning arrester is mainly by the U1 piezo-resistance, the U2 piezo-resistance, the U3 piezo-resistance, the U4 piezo-resistance, the U5 piezo-resistance, FU1 fusible link, FU2 fusible link, the D ceramic gas discharge tube, the PE earth connection forms.
Further improvement of the present invention is: connect with the D ceramic gas discharge tube after the U1 piezo-resistance in the lightning arrester and the parallel connection of U2 piezo-resistance, connect with the parallel circuits that U3 piezo-resistance and U4 piezo-resistance form again, these series circuit two ends respectively with the FU1 fusible link with electric to constant-current source (11) output AC with output L1 after the U5 piezo-resistance is in parallel and N1 again after the FU2 fusible link is connected.
Operation principle of the present invention is: lightning arrester 10 is being struck by lightning or surge voltage and when surpassing rated voltage; one road electricity is with voltage U 1 piezo-resistance (1) in the parallel circuits; U2 piezo-resistance (2); the resistance value of U3 piezo-resistance (3) and U4 piezo-resistance (4) sharply descends and conducting; make high-tension electricity pass through to be discharged by PE earth connection (9) after D ceramic gas discharge tube (8) is released the Lightning Transient overvoltage; another road electricity sharply descends with U5 piezo-resistance (5) resistance value and conducting in the parallel circuits; heavy current is blown FU1 fusible link (6) and FU2 fusible link (7) to cause outage, thereby has protected LED street lamp constant-current source and LED street lamp to avoid being struck by lightning or the infringement of surge voltage.
The invention has the beneficial effects as follows: be struck by lightning or during surge voltage, the high-tension electricity ground connection discharge that lightning arrester will be struck by lightning or surge voltage produces makes LED street lamp constant-current source and LED street lamp exempt from damage.
