Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, the utility model is described in further detail below in conjunction with drawings and the specific embodiments.Should be appreciated that specific embodiment described herein only is used for explaining the utility model, be not limited to the utility model.
A kind of LED emergency light that the utility model provides comprises the emergent indicating circuit that carries out the bright light indication when civil power cuts off the power supply.
With reference to Fig. 1, the schematic block circuit diagram of the LED emergency light that the utility model embodiment provides.
A kind of LED emergency light comprises: be the LED lamp 200 of luminous energy with electric energy conversion; Input termination civil power 500 is with the power circuit 100 of civil power 500 rectifications, filtering, step-down; The output of input termination power circuit 100, the rechargeable battery 300 of the electric energy of storage power circuit 100 outputs; Moved end 3 connects LED lamp 200, the first and does not connect the output of power circuit 100 in moved end 1, second not moved end 2 connect the output of rechargeable battery 300, selecting civil power 500 or rechargeable battery 300 be the single-pole double-throw switch (SPDT) SW1 that LED lamp 200 is powered; Also comprise: detect the output of termination power circuit 100, the output of power supply termination rechargeable battery 300, the emergent indicating circuit 400 that when power circuit 100 outages are civil power 500 outage, carries out the bright light indication.
With reference to Fig. 2, the circuit theory diagrams of the LED emergency light that the utility model embodiment provides.
The source electrode of junction type P-channel field-effect transistor (PEFT) pipe Q1 is as the output of the power supply termination rechargeable battery 300 of emergent indicating circuit 400, and anode, grid that drain electrode meets diode D1 pass through resistance R 1 ground connection; The grid of junction type P-channel field-effect transistor (PEFT) pipe Q1 is the output of the detection termination power circuit 100 of the emergent indicating circuit 400 of conduct simultaneously; The negative electrode of diode D1 connects the output of power circuit 100; Capacitor C 1 is series between power circuit 100 and the ground; Capacitor C 2 is series between the drain electrode and ground of junction type P-channel field-effect transistor (PEFT) pipe Q1; The drain electrode of the anode access node type P-channel field-effect transistor (PEFT) pipe Q1 of light-emitting diode D2, negative electrode is by resistance R 2 ground connection.
Below the operation principle of LED emergency light that the utility model is provided be described further.
The cardinal principle of the emergency light indicating circuit 400 of the LED emergency light that the utility model embodiment provides is for adopting rechargeable battery 300 as the power supply of the light-emitting diode D2 of emergent indicating circuit 400, adopt junction type P-channel field-effect transistor (PEFT) pipe Q1 as switching tube, the grid of junction type P-channel field-effect transistor (PEFT) pipe Q1 is by power circuit 100 controls.
In the situation of civil power 500 normal power supplies, power circuit 100 is normal power supply also, the moved end 3 of single-pole double-throw switch (SPDT) SW1 connects the first moved end 1 not, and this moment, LED lamp 200 was that civil power 500 is powered by power circuit 100, and rechargeable battery 300 charges by power circuit 100.
Because the grid of junction type P-channel field-effect transistor (PEFT) pipe Q1 connects the output of power circuit 100, thereby so junction type P-channel field-effect transistor (PEFT) pipe Q1 be that high level is in cut-off state because of grid; This moment, light-emitting diode D2 access failure power supply was not luminous.
When power circuit 100 outages are civil power 500 outage, thereby junction type P-channel field-effect transistor (PEFT) pipe Q1 is that low level is in conducting state because of grid.Because the source electrode of junction type P-channel field-effect transistor (PEFT) pipe Q1 connects the output of rechargeable battery 300, therefore the electric current of rechargeable battery 300 flows to drain electrode by the source electrode of junction type P-channel field-effect transistor (PEFT) pipe Q1, and flowing to light-emitting diode D2, this moment, light-emitting diode D2 entered operating state, carried out bright light.This moment, emergent indicating circuit 400 was indicated the particular location of this LED emergency light by bright light, thus make things convenient for the user determine this LED emergency light particular location and with the moved end 3 of single-pole double-throw switch (SPDT) SW1 connect second not moved end 2 these LED emergency lights open.
In sum, the LED emergency light that the utility model provides, by emergent indicating circuit 400, can after civil power 500 outages, carry out the particular location that bright light is indicated this LED emergency light, thereby solve the LED emergency light with rechargeable battery of the prior art after the civil power outage can not continue to provide illumination, the user is difficult to the clearly particular location of this LED emergency light, thereby is difficult to problem that this LED emergency light is opened.
The above is the utility model preferred embodiment only, is not limited to the utility model, all any modifications of doing within principle of the present utility model, is equal to and replaces and improvement etc., all should be included within the scope of the utility model protection.
