Background technology

Light fixture is used for to people, providing illumination at night, has a power failure suddenly or switch trip, and dark let us at the moment is in a rush, and personnel may cause in intensive place riot for the moment, gently injury to personnel, heavy threat to life.Therefore, the power failure emergency light has been arranged, provide floor light in the moment had a power failure, helped us to drive away dark fear.Yet in a single day existing power failure emergency light lights, until just can quit work in exhaustion of the accumulators or city power recovery, may have in during this period of time greatly the time we do not need illumination, cause waste of energy and light pollution; Or after the emergency light exhaustion of the accumulators, before city power recovery, we also will continue to provide illumination, because exhaustion of the accumulators can't provide.

The utility model content

The purpose of this utility model is effectively to overcome the deficiency of above-mentioned technology, and a kind of emergency light of controllable switch is provided, this controlled emergency light have a power failure or switch trip after, still can freely control the switch of light fixture, when not needing to throw light on, can close.

The technical solution of the utility model is achieved in that and comprises the single-pole double-throw switch (SPDT) be connected on civil power, it is characterized in that: a charging circuit in the output parallel connection of described single-pole double-throw switch (SPDT), one city's power detection circuit, one switch condition detection circuit and a LED driving power circuit, the output of described charging circuit is connecting a rechargeable battery, the output of described city power detection circuit is being connected a control circuit jointly with the output of switch condition detection circuit, the output of described LED driving power circuit is connecting a LED light source, and above-mentioned rechargeable battery and LED light source are electrically connected by control circuit.

In said structure, the input of described single-pole double-throw switch (SPDT) is connected on the live wire and zero line of civil power, the output of this single-pole double-throw switch (SPDT) has two contacts, and the one contact is connected on the zero line of above-mentioned civil power, and another contact is connected on the button of this single-pole double-throw switch (SPDT).

The beneficial effects of the utility model are: the utility model is in the normal situation of civil power the time, can control the LED driving power by single-pole double-throw switch (SPDT), thereby control the light on and off of LED light source, in the situation that during without civil power, single-pole double-throw switch (SPDT) is controlled rechargeable battery by switch condition detection circuit and control circuit and is powered to LED light source, reaches equally and by single-pole double-throw switch (SPDT), controls the purpose of turning on light, turning off the light.

The accompanying drawing explanation

Fig. 1 is schematic block circuit diagram of the present utility model.

Embodiment

The utility model will be further described below in conjunction with drawings and Examples.

With reference to shown in Figure 1, the utility model has disclosed a kind of controlled emergency light, this controlled emergency light comprises the single-pole double-throw switch (SPDT) 10 be connected on civil power, the input of single-pole double-throw switch (SPDT) 10 is connected on the live wire and zero line of civil power, and the output of this single-pole double-throw switch (SPDT) 10 has two contacts, and the one contact is connected on the zero line of above-mentioned civil power, another contact is connected on the button of this single-pole double-throw switch (SPDT) 10, therefore, by the effect of single-pole double-throw switch (SPDT) 10, can realize the function of power on/off.In parallel on two contacts of the output of single-pole double-throw switch (SPDT) 10 have charging circuit 20, mono-city's power detection circuit 30, a switch condition detection circuit 40 and a LED driving power circuit 50, the output of charging circuit 20 is connecting a rechargeable battery 201, the output of city's power detection circuit 30 is being connected a control circuit 60 jointly with the output of switch condition detection circuit 40, the output of LED driving power circuit 50 is connecting a LED light source 501, and above-mentioned rechargeable battery 201 is electrically connected by control circuit 60 with LED light source 501.

By above-mentioned circuit structure, we are described the course of work of the present utility model, and operating state of the present utility model has four kinds:

1, when not having a power failure, and when single-pole double-throw switch (SPDT) 10 is placed in " ON " end, connect civil power, civil power gives LED light source 501 power supplies by LED driving power circuit 50, light fixture is normally lighted, and charging circuit 20 gives rechargeable battery 201 chargings, and city's power detection circuit 30 and switch condition detection circuit 40 detect signal, city's power detection circuit 30 and switch condition detection circuit 40 stop rechargeable battery 201 to LED light source 501 power supplies by control circuit 60, and now light fixture is normally lighted;

2, when not having a power failure, and single-pole double-throw switch (SPDT) 10 is placed in " OFF " when end, and civil power disconnects, and LED driving power circuit 50 can not give LED light source 501 power supplies, and light fixture extinguishes, and charging circuit 20 can not give rechargeable battery 201 chargings; City's power detection circuit 30 and switch condition detection circuit 40 do not detect signal, and city's power detection circuit 30 and switch condition detection circuit 40 stop rechargeable battery 201 to LED light source 501 power supplies by control circuit 60, and now light fixture extinguishes;
