Abstract

A lamp that can be used for emergency illumination concurrently consists of a lamp holder and a lampshade. A lighting tube and a circuit wafer are arranged in the lamp holder. A rectifier, a relay and a ballast are arranged on the circuit wafer to provide electric energy for the lighting tube to give light. The utility model is characterized in that a detection circuit is connected with the firewire of a switch, a convertor is connected with the detection circuit and the convertor is connected with the touch switch of the lighting tube. The rectifier connects with an isolating circuit and a battery, and electricizes the battery connected with the convertor. The detection circuit can induce whether the firewire power is interrupted or not. When being interrupted, the convertor can start the same lighting tube to give light by using the electric energy provided by the battery.

Description

Have the light fixture that Emergency Light is used concurrently

The utility model relates to a kind of lighting.

General house and public place are most important for the lasting illumination that keeps lighting.The public safety of public place is subjected to generally paying attention to now, and especially when outage (no matter temporary interruption of the scheduled outage of Utilities Electric Co. or contingency), light fixture continues to keep the luminous usefulness that can be strain and escape illumination.Therefore the dealer develops various Emergency Light light fixture gradually, for the usefulness of house, workplace and public place.The Emergency Light lamp of commonly using is mainly an independent working flare, and it accepts power source charges on ordinary days, and accumulates electric energy with battery, when having a power failure by the required electric energy of battery supplied Emergency Light.And the illuminating lamp of commonly using also is an independent working flare, and it is accepted ac power supply on ordinary days and be luminous.

Other has a kind of light fixture as shown in Figure 3, and this light fixture 1 is mainly with shared same lamp socket 13 of Emergency Light lamp and general illumination lamp and lampshade 14, and with an Emergency Light fluorescent tube 12 external uninterrupted power supplys (UPS), makes the lamp luminescence illumination.This light fixture, though illuminating lamp tube 11 and Emergency Light fluorescent tube 12 in same lamp socket, but still symbolic animal of the birth year Different Individual independently mutually.Therefore light fixture be if will have the double duty of general illumination and Emergency Light concurrently, fluorescent tubes (bubble) more than essential two groups at least in the lamp socket then, and promptly illuminating lamp tube and Emergency Light fluorescent tube are provided with comparatively loaded down with trivial details and uneconomical.

The purpose of this utility model is: a kind of light fixture that Emergency Light is used that has concurrently is provided, and fluorescent tube or bulb that normal illumination is used also can luminous lightings when having a power failure.Make it to have the double duty of general illumination and Emergency Light.

The purpose of this utility model is achieved in that and is provided with fluorescent tube and circuit board in the lamp socket, and circuit board mainly comprises a rectifier, relay, stabilizer, and the live wire of power switch front end is connected with fluorescent tube after connecting a circuit for detecting, converter and touch switch; Converter also connects a buffer circuit, and buffer circuit is communicated with battery.Behind the rectifying and wave-filtering, power supply is to battery charge; Whether borrow circuit for detecting induction live wire power supply to interrupt, relay control touch switch during interruption, the electric energy of battery is changed the back to same lamp tube power supply illumination by converter (inverter) if connecting another circuit.

The utlity model has following advantage: same fluorescent tube or bulb still can throw light on when having a power failure, and have normal, Emergency Light double duty.Simplified the structure of fluorescent tubes more than dual-purpose lamp must possess two groups in the prior art, can reduce cost and the consumption expenditure, and simple installation.

Accompanying drawing provides embodiment of the present utility model.

Fig. 1 is a schematic perspective view of the present utility model;

Fig. 2 is the utility model circuit diagram;

Fig. 3 is for commonly using the light fixture three-dimensional exploded view.

Below in conjunction with accompanying drawing the utility model is elaborated.

See also Fig. 1, shown in Figure 2, the design has the light fixture that Emergency Light is used concurrently about a kind of, and this light fixture 2 mainly comprises lamp socket 23 and lampshade 24; Be provided with fluorescent tube 21 or bulb and circuit board in the lamp socket.Wherein lighting circuit is to connect a stabilizer 228 and fluorescent tube 21 and switch with power line.

This creation focuses on designing a loop, and this loop comprises:

One circuit for detecting 221 and converter 222, circuit for detecting one end connects power line, and the other end is connected to converter 222 (being inverter again).Converter 222 other ends are connected the state that formation can be switched on fluorescent tube 21 touch switch 220.Converter connects battery pack 225 in addition.

One rectifier 223 and battery pack 225, rectifier one end connects power line, and the other end connects buffer circuit 224 and battery pack.Charge to battery pack 225 after the rectification.Battery pack links to each other with converter.

One relay 226 connects the touch switch 22 of fluorescent tube 21, control touch switch 220 selectivity and power line or converter 222 break-makes.

When normal power supply when outage (non-), electric current is by power line, and lights fluorescent tube 21 through stabilizer 228.Charge to battery pack 225 by rectification simultaneously.

When having a power failure, after detecting electrical equipment 221 predicts, even relay 226 fluorescent tube touch switch 220 disconnect with power line and are connected with converter 222, and converter 222 is given in battery pack 225 power supplies simultaneously, the loop of illuminating lamp tube 21 power supplies this moment, by the converter power supply, make fluorescent tube 21 continue luminous use by battery pack 225, need not change.

Above-mentioned is the utility model one preferred embodiment, and all equalizations of doing according to present patent application change, and all belong to the application's protection domain.
