Abstract
The utility model discloses an LED street lamp device with a lightning arrester, wherein the lightning arrester is mainly composed of the following components: a U1 varistor, a U2 varistor, a U3 varistor, a U4 varistor, a U5 varistor, a FU1 fuse, a FU2 fuse, a D ceramic gas discharge tube and a PE ground wire. When lightning or surge voltage occurs, the lightning arrester performs grounding discharging on the high voltage which is generated by lightning or surge voltage, and the fuse is broken, thereby preventing damage of a constant current source of the LED street lamp and damage of the LED street lamp.
Description
Technical field
The utility model relates to the street lamp field, relates 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 electric current fuse 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 utility model, promptly one lightning arrester is set at LED street lamp constant-current source front end, 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 produced, LED street lamp constant-current source and LED street lamp exempt from damage.
In order to achieve the above object, the technical solution of the utility model is:
A kind of LED road lamp device that installs lightning arrester additional of the present utility model, 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 to supply the LED street lighting to LED street lamp output low-voltage DC after the AC rectification of input, 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 is formed.
Further improvement of the utility model is: connect with the D ceramic gas discharge tube after 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 are formed again, these series circuit two ends respectively with the FU1 fusible link with after the FU2 fusible link is connected again with output L1 after the U5 piezo-resistance is in parallel and N1 to constant-current source (11) output AC.
Operation principle of the present utility model 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 discharge by PE earth connection (9) after D ceramic gas discharge tube (8) is released the thunder and lightning temporary 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 beneficial effects of the utility model are: 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 produced makes LED street lamp constant-current source and LED street lamp exempt from damage.
