Description

Improved power-cut emergency lighting device

The utility model relates to the technical field of power-cut emergency lighting.

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 this utility model 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 this utility model is achieved by the following technical solution: improved power-cut emergency lighting device, constitute with the lead etc. 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.

Below in conjunction with drawings and Examples structure of the present utility model and advantage are further elaborated.

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 ₁, commutation diode D ₁-D ₄, chip IC ₁And peripheral cell triode Q ₁, capacitor C ₁, resistance R ₁-R ₅Deng composition; Oscillating circuit is by chip IC ₂And Resistor-Capacitor Unit C on every side ₂-C ₄, R ₆-R ₉Form; High-voltage rectifier is by transformer T ₂, metal-oxide-semiconductor, commutation diode D ₅-D ₁₂Form; DC control circuit is by triode Q ₂-Q ₄And peripheral Resistor-Capacitor Unit R ₁₀-R ₁₄, C ₅-C ₇, D ₁₅Deng composition; Relay is J ₁-J 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, (NC) is unsettled for normally-closed contact; 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 ₄Movable contact link to each other relay J with input 1 end of inverter controller 2 ₄Normally opened contact and the Q of rectification constant voltage charging circuit ₁Link 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 the lead that is connected between inverter controller 2 and the fluorescent lamp 4 only needs (Lc, Lb, Ld, Le) four, lacks two than the six roots of sensation of prior art.
