Description

Improved power failure emergency lighting device

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

The power failure emergency lighting device is mainly composed of batteries, inverter controllers, lamps, and connecting wires between lamps and inverter controllers. In the prior art, due to the unreasonable design of the inverter controller, when fluorescent lamps are used as lighting fixtures to connect to the inverter controller, there are as many as six connecting wires between the two, which are respectively the 220V phase of the ballast. line entry line, ballast phase line output line, fluorescent lamp phase line entry line, neutral line and two starter return lines. When there is 220V mains power, the output line of the ballast phase line and the incoming line of the fluorescent lamp phase line are connected by a relay, and the two return lines of the starter are also connected by a relay, and the six lines form a power supply circuit to use the mains power; When there is a power failure, the aforementioned relay is disconnected, and the power supply of the inverter controller supplies power to the fluorescent lamp through another loop formed by the fluorescent lamp phase line entering line and the neutral line. Obviously, such a connection design is complicated. Also due to the unreasonable design of the inverter controller, when energy-saving lamps are used as lighting fixtures to connect with the inverter controller, there are still as many as four connecting wires between the two. Line, ballast phase line output line, energy-saving lamp phase line and neutral line. When there is 220V mains power, the relay connects the phase line output line of the ballast to the phase line of the energy-saving lamp, and the four wires form a power supply circuit, and the energy-saving lamp uses the mains power; The power supply of the controller supplies power to the energy-saving lamp through another loop formed by the energy-saving lamp phase line and the neutral line. It can be seen that when the inverter controller is powered by the battery, it uses a different power supply circuit connection than the 220V mains, which is the root cause of the complicated connection, many connections, and high material consumption.

The purpose of this utility model is to overcome the shortcomings of the above-mentioned prior art and provide a power failure emergency lighting device that can reduce the connecting wires between the lamp and the inverter controller, thereby simplifying installation and saving materials.

The inverter controller 2 includes a rectification constant voltage charging circuit, an oscillation circuit, a high voltage rectification circuit, a DC control circuit, a relay, etc., wherein the rectification constant voltage charging circuit consists of a transformer T ₁ , rectification diodes D ₁ -D ₄ , chip IC ₁ and Its peripheral components are composed of triode Q ₁ , capacitor C ₁ , resistors R ₁ -R ₅ , etc.; the oscillation circuit is composed of chip IC ₂ and its surrounding resistance-capacitance components C ₂ -C ₄ , R ₆ -R ₉ ; the high-voltage rectifier circuit is composed of transformers T ₂ , MOS tube, rectifier diode D ₅ -D ₁₂ ; the DC control circuit is composed of triode Q ₂ -Q ₄ and peripheral resistance-capacitance components R ₁₀ -R ₁₄ , C ₅ -C ₇ , D ₁₅ ; the relay is J ₁ -J ₄ . The 220V mains is connected to the input g and h terminals of the inverter controller 2, the battery 1 is connected to the input j and l terminals of the inverter controller 2, and the 220V mains phase line La is connected to the normally open contact of the relay _J1 , the phase line input line Lc of the ballast is connected to the moving contact of the relay _J1 , and the normally closed contact (NC) of the relay _J1 is connected to the high output of the high voltage rectifier circuit; the circuit line Ld of the starter 5 is connected to the relay J ₂ , the other circuit line Lb is connected to the normally open contact of relay J ₂ , and the normally closed contact (NC) is suspended in the air; the neutral line Le is connected to the moving contact of relay J ₃ , and the normally closed contact (NC) of relay J ₃ The open contact is connected to the input h terminal of the inverter controller 2, the normally closed contact (NC) of the relay J ₃ is connected to the low output of the high voltage rectifier circuit; the moving contact of the relay J ₄ is connected to the input of the inverter controller 2 Terminal 1 is connected, the normally open contact of relay J ₄ is connected with Q ₁ of the rectification constant voltage charging circuit, and the normally closed contact (NC) of relay J ₄ is connected with the input terminals of the oscillation circuit, high voltage rectification circuit and DC control circuit.

When the 220V mains is normally powered, the moving contacts of the relays J ₁ -J ₄ are connected to the normally open contacts, and the 220V mains passes through the 220V mains phase line La, the ballast phase line input line Lc, the ballast The power supply loop formed by the device 3, the ballast phase line output line Lf, the fluorescent lamp 4, the neutral line Le and the input h terminal of the inverter controller 2 supplies power to the fluorescent lamp 4, and the starter loop line Lb and Ld are guided by the relay _J2 To make the fluorescent lamp 4 energized to work, at the same time, the commercial power charges the battery 1 through the inverter controller 2 .

When the 220V mains power fails, the moving contacts of the relays J ₁ -J ₄ are separated from the normally open contacts and connected to the normally closed contacts (NC), and the battery 1 is charged to the battery through the normally closed contacts (NC) of the relay J ₄ .
