Abstract
An online emergency light comprises a power input end, a capacitance depressing voltage circuit, a rectifier filtering circuit, a rechargeable battery and a LED luminous tube. The utility model is characterized in that an electronic switch formed by a triode is connected in tandem between the battery and the LED luminous light, a control electrode of the electronic switch is connected with an output end of the rectifier filtering circuit and an output end of a photosensitive circuit respectively. The utility model utilizes the triode to control the work of the LED luminous tube, of which the circuit is simpler. A switch of the triode is controlled together by a voltage signal of the power input end and a output signal of the photosensitive circuit at the same time, only when the environmental light is insufficient and the power input is turn-off, the LED luminous tube lights, by which the automatic control is realized, thereby the emergency light can be inserted in an outlet for a long time and used conveniently as the online emergency light.
Description
Technical field the utility model relates to a kind of light fixture, is specifically related to a kind of emergency light.
The existing emergency light of background technology generally adopts fluorescent lamp as light fixture, adopts relay to carry out switching controls, the circuit complexity, and the cost height, and also for having a power failure on daytime or evening, prior art does not have full automation control, uses inconvenient.
The summary of the invention the purpose of this utility model is to disclose the simpler control of a kind of circuit small-sized online emergency light of automation more.
The purpose of this utility model is to realize like this, it comprises power input, capacity voltage dropping circuit, current rectifying and wave filtering circuit, chargeable battery and the LED luminous tube that connects successively, it is characterized in that: between battery and LED luminous tube, be serially connected with an electronic switch of forming by triode, the control utmost point of electronic switch, be connected respectively to the output of current rectifying and wave filtering circuit and the output of a photosensitive circuit.
Emergency light of the present utility model adopts triode to control the work of LED luminous tube as switch element, and circuit is simpler.The switch of triode is subjected to the common control of the output signal of the voltage signal of power input and photosensitive circuit simultaneously, have only when ambient light deficiency and power supply input outage, such as evening during grid power blackout, the LED luminous tube is just lighted, and evening, electrical network had electricity, perhaps daytime grid power blackout, emergency light can be not bright, use as online emergency light so should anxious lamp can be inserted in for a long time in the supply socket, the control of work full automation is used more convenient.
Description of drawings Fig. 1 is the circuit theory diagrams of an embodiment of the utility model.
With reference to the accompanying drawings, embodiments of the invention are described below the embodiment.
In the accompanying drawing 1, AC1, AC2 are power input, be connected with the power supply base of external electrical network during use, when electrical network has electricity, the AC power of AC1, AC2 input, through the capacity voltage dropping circuit step-down of forming by capacitor C 1, resistance R 1, form rectification circuit rectification and capacitor C 2 filtering by diode D1, D2, after the voltage-stabiliser tube D3 voltage stabilizing, the direct voltage of output 6V, this voltage charges to the rechargeable battery B1 that is made up of the Ni-MH battery group by D4.The effect of D4 is that the voltage reversal that prevents battery is input to current rectifying and wave filtering circuit.
LED luminous tube D5-D8 forms illuminating source, between LED luminous tube and battery B1, is serially connected with the electronic switch of being made up of triode Q1, and Q1 requires multiplication factor higher, also can adopt two triodes to form the form of multiple tube.The control utmost point of electronic switch, it also is the base stage of Q1, the output that is connected to current rectifying and wave filtering circuit on the one hand also is the output of capacitor C 2, is also connected to the output of the photosensitive circuit of being made up of Q2 and photo resistance RG on the other hand, is subjected to the control of both output signals simultaneously.When external electrical network had electricity, current rectifying and wave filtering circuit had VD, and Q1 ends, and LED can not light; When external electrical network was cut off the power supply, current rectifying and wave filtering circuit did not have output voltage, if at this moment be that daytime or ambient light are enough, then Q2 conducting also makes Q1 end, and LED can not light.Have only at night or other ambient light deficiencies, and during the external electrical network outage, at this moment Q2 ends, current rectifying and wave filtering circuit does not have output voltage yet, so Q1 conducting immediately, the LED luminous tube is lighted immediately, provides emergency lighting to the user.
Owing to should adopt Ni-MH battery and LED luminous tube by anxious lamp, cooperate electronic switch to control the work of LED luminous tube, so circuit is simpler, cost is lower.And work that should anxious lamp can realize full-automatic control, can be inserted in for a long time in the supply socket and use as online emergency light, uses more convenient.
