Please refer to Fig. 7, is the schematic diagram of power module of the emergency lighting circuit of the embodiment of the present invention.The power supply of emergency lighting circuit provides constant electric current by power module, and the superperformance of power module provides good operating voltage for lamp plate, and power module work when civil power accesses for integrated circuit power supply, charges the battery simultaneously.Concrete, power module has output constant current, constant voltage, and for LED lamp panel module provides good operating voltage, when civil power accesses, power module work, provides a voltage to light LED lamp panel module.By another winding of power module, through diode D5 rectification, current-limiting resistance R4, filter capacitor C16, provide a direct voltage, triode Q1, thyristor TL1 form voltage stabilizing circuit, resistance R 15 is controlled the conducting size of triode Q1, capacitor C 17 makes thyristor TL1 working stability, resistance R 16, R17 form sample resistance, for the charging of battery provides stable operating voltage.This voltage charges the battery through diode D11 current limliting.Resistance R 21 current limlitings, capacitor C 19 filtering provide operating voltage to the second processor U4, and protective circuit is controlled by the second processor U4 and the 3rd processor U5, controls overcharging, crossing and put, overcurrent etc. of battery.The 3rd processor U5 inside is two groups of metal-oxide-semiconductors, reduces battery operated conducting internal resistance, and the second processor U4, the 3rd processor U5 work are self to be low-power consumption microampere order, make like this product can have the standby of enough length.Triode Q3, resistance R 23, resistance R 24, resistance R 25, protective circuit form red green indicating circuit.When the work of civil power access charge protector of battery, base current enters ground through resistance R 24 through protective circuit, now triode Q3 conducting, and electric current is lighted red led through triode Q3, resistance R 25, and indication circuit is just in charged state.When battery is full of, protective circuit quits work because overcharging, and triode Q3 base stage is not because there is no earth current cut-off work, and now electric current is lighted green indicating lamp through resistance R 23, represents that battery has been full of electricity.
Concrete, in the present invention, control module is comprised of U6 and peripheral circuit.C18 is filter capacitor, make first processor U6 working stability, when civil power accesses, the burning voltage providing through triode Q1, the 4th pin of access first processor U6, first processor U6 detects the 4th pin voltage, internal circuit resets, the 6th pin is high potential, and triode Q2 cut-off, does not work in emergent LED lamp panel module.When civil power disconnects, the 4th pin loss of voltage, first processor U6 detects also time delay 2-4 second, enter emergency rating, locking timing controlled time, the 6th pin output electronegative potential, triode Q2 conducting, cell voltage is lighted emergent required LED battle array example through triode Q2, realizes emergency lighting.Along with the continuity of emergency lighting time, reach after the timing of first processor U6 locking, the 6th pin output high potential, triode Q2 cut-off, LED lamp plate extinguishes.If now need emergency LED lamp plate bright, first processor U6 also can realize, and the 5th pin of first processor U6 opens or closes control for forcing, and S1 is force switch button, clicks switch lamp Chang Liang, as clicked lamp, often goes out again, and with this, circulates.
Meanwhile, as an embodiment, the course of work of light adjusting circuit is as follows: by power module after diode D6 rectification, C15 filtering, R30 current limliting, D9 voltage stabilizing, for control chip U7 provides stable operating voltage.When user opens switch on wall, power module work, by transformer, through current-limiting resistance R4, rectifier diode D7, filter capacitor C23, the 4th triode Q6 base stage, obtained electric, the 4th triode Q6 conducting, 1 pin of control chip is electronegative potential over the ground, 3 pin are exported electronegative potentials simultaneously, control the 5th triode Q5 conducting, due to the conducting of the 5th triode Q5, the grid voltage of field effect transistor Q4 is also along with decline, the voltage of Q4 source electrode is controlled, and the brightness of LED lamp panel module also changes along with the variation of voltage.When user turn-offs switch on wall, power module is not worked, and LED lamp plate breath goes out, while the 4th triode Q6 base stage dead electricity, and the 4th triode Q6 does not work.Due to the energy storage effect of the 5th capacitor C 22, control chip U7 is maintaining the work of awaiting orders of short time, counting internal data.When user's unlocking wall switch again, power module work, the 4th triode Q6 base stage again electric, 1 pin of control chip U7 is electronegative potential again, the internal trigger of control chip U7, its 4 pin output electronegative potential, because R34 resistance is less, strengthen the conducting to triode Q5, the voltage that the gate clamped of field effect transistor Q4 can not bright light to LED lamp plate, now LED lamp plate does not reach the voltage of bright light, and lamp does not work.The size of the 11 resistance R 33, the 12 resistance R 34 has determined the brightness of LED lamp plate.When user turn-offs again----unlocking wall switch, 1 pin of control chip U7 is electronegative potential again, now control chip U7 stops output, the 5th not conducting of triode Q5, the now conducting of field effect transistor Q4 is the strongest, and output voltage is maximum, and LED lamp plate is the brightest, the operation of user to switch on wall, realizes light modulation repeatedly.
As a preferred embodiment, when illuminating lamp of the present invention is used as domestic lighting, light modulation has three gears, and can arbitrarily adjust the brightness of each grade, light modulation object is all in order to meet people's different light intensity of needs under different occasions at home, for example, when seeing TV dark possibly, brighter possibly in the time of reading, can follow according to different clients and adjust at the different environment of application the brightness that LED is different.
In order to realize, shake control and emergent, the last step that we can the transfer the files emergent standby mode that is set to have a power failure, can realize at night and have a rest and do not want to make lamp bright, can know again it when is to have a power failure, can also realize the rear emergency lighting that has a power failure, and the lighting time of power-cut emergency lighting can be set, according to customer requirements, can do the different time and control.When disaster or urgent need illumination, can take off again when torch use, can freely control and open or close.Internal cell is used LiFePO4, has perfect battery to control and protective circuit, safe and reliable.
To sum up, lighting circuit of the present invention, not only in power-off, emergency light makes an immediate response, the purposes of performance emergency lighting, and user can regulate according to application scenario the brightness of lamp, thus the lighting hours that extends emergency light, lower, the easy to operate and energy savings of cost.This system applies arranges panel, can be set flexibly the operating time of emergency lighting according to people's demand, the phenomenons such as electric energy that avoid waste, and this emergency lighting system is installed simple, convenient and reliable, the occasion that need to throw light on while being widely used in power-off.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
