Abstract
The invention discloses an LED (Light-Emitting Diode) street lamp device additionally provided with a lightning arrester. The lightning arrester mainly comprises U1 to U5 piezoresistors, an FU1 fuse wire, an FU2 fuse wire, a D ceramic gas discharge tube, and a PE earthing wire. When being stroked by lightning or surge voltage, the lightning arrester leads high voltage generated by the lightning or surge voltage to be earthed for discharging, the fuse wire is burnt out so as to lead an LED street lamp constant source and an LED street lamp to be free 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 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 invention; 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, 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; Said LED street lamp constant-current source is with supplying the LED street lighting to LED street lamp output low-voltage DC behind the AC rectification of input, and described lightning arrester is mainly by the U1 piezo-resistance, the U2 piezo-resistance; The U3 piezo-resistance, U4 piezo-resistance, U5 piezo-resistance; The FU1 fusible link; The FU2 fusible link, the D ceramic gas discharge tube, the PE earth connection is formed.
Further improvement of the present invention is: connect with the D ceramic gas discharge tube after 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 parallelly connected and N1 to constant-current source (11) output AC.
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 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, and heavy current blows 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 produced makes LED street lamp constant-current source and LED street lamp exempt from damage.
