Power-cut emergency lighting device mainly is made of with the lead etc. that is connected between the inverter controller battery, inverter controller, light fixture and light fixture.In the prior art, because the design of inverter controller is unreasonable, when making lighting and be connected with inverter controller with fluorescent lamp, connection lead between the two has more than the six roots of sensation, and they are respectively that the 220V phase line of ballast enters line, ballast phase line output line, fluorescent lamp phase line and enters line, zero line and two starter return lines.When the 220V civil power, ballast phase line output line and fluorescent lamp phase line enter line and are connected by relay, and two starter return lines are also connected by relay, and six roots of sensation line constitutes current supply circuit and uses civil power; When the 220V mains failure, aforementioned relay disconnects, and the power supply of inverter controller is powered to fluorescent lamp by another loop that the fluorescent lamp phase line enters line and zero line formation.Obviously, such line design is complicated.It is same because the design of inverter controller is unreasonable, when making lighting and be connected with inverter controller with electricity-saving lamp, connection lead between the two still has four more than, and they are respectively that ballast 220V phase line enters line, ballast phase line output line, electricity-saving lamp phase line and zero line.When the 220V civil power, relay is connected ballast phase line output line and electricity-saving lamp phase line, and four lines constitute current supply circuit, and electricity-saving lamp uses civil power; When the 220V mains failure, above-mentioned relay disconnects, and the power supply of inverter controller is powered to electricity-saving lamp by another loop that electricity-saving lamp phase line and zero line constitute.As can be seen, adopting the current supply circuit line be different from the 220V civil power when inverter controller is battery-powered, is to cause that line is complicated, line is many, consume the root more than the material.
The purpose of patent of the present invention is for overcoming above-mentioned the deficiencies in the prior art part, and a kind of lead that is connected that reduces between light fixture and the inverter controller is provided, thereby can simplify installation, save the power-cut emergency lighting device of material.
The purpose of patent of the present invention is achieved by the following technical solution: a kind of power-cut emergency lighting device, constitute with the lead that is connected between the inversion control by the ballast of battery, inverter controller, light fixture, light fixture and light fixture, inverter controller includes charging circuit, oscillating circuit, high-voltage rectifier, relay etc., special feature is to form unique current supply circuit line between light fixture and the inverter controller, and this current supply circuit is linked in sequence and is formed by ballast phase line input line, ballast, ballast phase line output line, light fixture, zero line; The high-voltage rectifier output of 220V civil power phase line and inverter controller is connected with ballast phase line input line by relay.Further, during corresponding fluorescent lamp, establish two return lines that a relay connects starter.
Be further elaborated below in conjunction with the structure and the advantage of drawings and Examples patent of the present invention.
Embodiment one:
Referring to Fig. 1 and Fig. 3, present embodiment is with the light fixture of fluorescent lamp 4 as emergency lighting.Inverter controller 2 includes rectification constant voltage charging circuit, oscillating circuit, high-voltage rectifier, DC control circuit, relay etc., and wherein the rectification constant voltage charging circuit is by transformer T

4The 220V civil power is connected to input g, the h end of inverter controller 2, and 1 on battery is connected to input j, the l end of inverter controller 2, and 220V civil power phase line La is connected to relay J
1Normally opened contact, ballast phase line input line Lc succeeds electrical equipment J
1Movable contact, relay J
1The high position output of normally-closed contact NC and high-voltage rectifier link to each other; The return line Ld of starter 5 is connected to relay J
2Movable contact, its another return line Lb is connected to relay J
2Normally opened contact, normally-closed contact NC is unsettled; Zero line Le is connected to relay J
3Movable contact, relay J
3The input h end of normally opened contact and inverter controller 2 link to each other relay J
3The low level output of normally-closed contact NC and high-voltage rectifier link to each other; Relay J

4Normally-closed contact NC link to each other with the input of oscillating circuit, high-voltage rectifier, DC control circuit.
When 220V civil power normal power supply, each relay J
1-J
4Movable contact and normally opened contact connect, the 220V civil power is powered to fluorescent lamp 4 by the current supply circuit that the input h end by 220V civil power phase line La, ballast phase line input line Lc, ballast 3, ballast phase line output line Lf, fluorescent lamp 4, zero line Le and inverter controller 2 constitutes, and starter return line Lb, Ld are by relay J
2Conducting makes fluorescent lamp 4 energising work, and meanwhile, civil power charges to battery 1 by inverter controller 2.
When the 220V mains failure, each relay J
1-J
4Movable contact break away from normally opened contact, connect with normally-closed contact NC, battery 1 passes through relay J
4Normally-closed contact NC to power supplies such as oscillating circuit, high-voltage rectifier, DC control circuits, make the high position output of high-voltage rectifier produce the 600V alternating current, and export the current supply circuit that constitutes by the low level of importing line Lc, ballast 3, ballast phase line output line Lf, fluorescent lamp 4, zero line Le and high-voltage rectifier by the ballast phase line and power to fluorescent lamp 4, make fluorescent lamp 4 keep energising work, two starter return line Lb, the Ld of this moment are by relay J
2Open circuit.
As seen, still be battery 1 power supply no matter by the 220V civil power, the current supply circuit line of present embodiment is identical Lc, Lb, Ld, Le, thereby inverter controller 2 only needs four of Lc, Lb, Ld, Le with the lead that is connected between the fluorescent lamp 4, and lacks two than the six roots of sensation of prior art.
