Description
[technical field]
The present invention relates to the emergency lighting technical field, the cut starting illuminating apparatus of particularly a kind of energy timer-controlled self-inspection.
[background technology]
At present, the fire emergency lamp of emergency lighting is widely used in various public arenas, Chinese patent discloses a kind of energy-saving corridor fire emergency lamp for No. 200420120794.7, include auxiliary relay J, DC power supply U, capacitor C and LED, between the positive pole of auxiliary relay J and DC power supply, be provided with the normal opened contact JK1 of auxiliary relay J.During normal the use, in ask that the coil of relay is charged, normal opened contact JK1 closure, normally closed contact JK2 disconnects, the civil power after transformation, rectification is the DC power supply charging, powers for light-emitting diode simultaneously; When civil power disconnected, normal opened contact disconnected, the normally closed contact closure, and DC power supply is connected with light-emitting diode.The same with present most emergency lights, all be to play illumination when having a power failure, the rechargeable battery by inside provides illumination energy, and non-outage is charged to battery by civil power.Whether yet there is a defective in this emergency light, does not have the function of timer-controlled self-inspection, can not prejudge it and lose efficacy or damages, and find just that when power failure its cisco unity malfunction, illuminating lamp do not work, and this will cause great inconvenience.
[summary of the invention]
For addressing the above problem, main purpose of the present invention is to provide a kind of cut starting illuminating apparatus that can timer-controlled self-inspection, judges by timer-controlled self-inspection whether emergency light lost efficacy or damage.
For achieving the above object, technical scheme of the present invention is:
The cut starting illuminating apparatus of a kind of energy timer-controlled self-inspection comprises multivibrator, the drive circuit that is connected with multivibrator, the startup self check relay that is connected with drive circuit and warning circuit and is connected in the fire emergency lamp basic circuit that starts between self check relay and the warning circuit.
Compared to prior art, the cut starting illuminating apparatus of the present invention's energy timer-controlled self-inspection has a power failure by simulation, and timer-controlled self-inspection judges that can the blackout period emergency light play the effect of illumination, prejudge it and whether lost efficacy or damage, cause unnecessary loss when avoiding having a power failure.
[description of drawings]
Fig. 1 is a theory diagram of the present invention.
Fig. 2 is circuit theory diagrams of the present invention.
[embodiment]
See also shown in Figure 1ly, a kind of cut starting illuminating apparatus that can timer-controlled self-inspection of the present invention comprises multivibrator, the drive circuit that is connected with multivibrator, the startup self check relay that is connected with drive circuit and warning circuit and is connected in fire emergency lamp basic circuit between startup self check relay and the warning circuit.Wherein, civil power is connected to the fire emergency lamp basic circuit through power supply, self check relay.Multivibrator output high level then begins self check, and drive circuit drives the self check relay contact and disconnects, and simulation has a power failure; Simultaneously, drive circuit also drives warning circuit during self check, reports to the police when fire emergency lamp basic circuit output low level.Fire emergency lamp basic circuit output low level shows that the bulb no current passes through.Fire emergency lamp basic circuit lamp when continuing to have a power failure is bright, and of short duration simulation has a power failure to determine according to the height of output level whether this emergency light is normal, but not period is given the charging of fire emergency lamp basic circuit by power supply in power failure.
See also shown in Figure 2, resistance R 7, R8, R9, R10 that multivibrator includes field effect transistor Q4, Q5, capacitor C 2, C3 and is connected in parallel.The triode Q7 that drive circuit includes triode Q6, is connected with triode Q6; Wherein, the base stage of triode Q6 is by the base stage that resistance R 11 is connected with multivibrator, emitter passes through resistance R 12 connection triode Q7, and the grounded emitter of triode Q7, collector electrode connects self check relay K 4.In addition, the emitter of triode Q6 also is connected to warning circuit.Warning circuit includes triode Q1, connects the triode Q3 of triode Q1 collector electrode, the buzzer of connection triode Q3 emitter and the thyristor Q2 that links to each other with the triode Q6 emitter of drive circuit by a resistance R 6 by a resistance R 5.The fire emergency lamp basic circuit connects the base stage of triode Q1 by a resistance R 4.
Obtain the direct voltage of 14V after the filtering of civil power through transformer T1 transformation, bridge rectifier D1 rectification and filter capacitor C1, this direct voltage is just often given the battery BT1 charging of fire emergency lamp basic circuit at civil power.Multivibrator is periodically exported high-low level, high level only continues 10ms during the self check, and the multivibrator output signal is through triode Q6, wherein leads up to triode Q7 control relay K4 then, other one tunnel control thyristor Q2, thereby control buzzer.If civil power is normal and be in during the non-self check, multivibrator output low level then, relay K 4 normally-closed contact closures, relay K 2 coils of fire emergency lamp basic circuit have the power supply power supply, contact 1 closure then, 14V voltage is given battery BT1 charging, and contact 2 disconnects, and the voltage on the battery BT1 fails to supply with bulb DS1, electric current on the sample resistance R3 is zero, therefore the potential difference at resistance R 3 two ends is 0, and triode Q1 ends, and its collector voltage is 14V, triode Q3 emitter voltage is 13.3V, but because this moment, thyristor Q2 controlled very low level, not conducting of thyristor Q2, buzzer is not reported to the police.When multivibrator output high level then begins to enter self check, simulate triode Q5 drain electrode output high level when having a power failure, through triode Q6 emitter following, triode Q7 saturation conduction, relay K 4 coils have electric current, its normally-closed contact disconnection.Under the normal condition, the not power supply of relay K 2 coils this moment, contact 1 disconnects, contact 2 closures, battery BT1 gives bulb DS1 power supply, and sample resistance R3 has electric current, and there is potential difference at the resistance two ends.Triode Q1 base stage obtains high level and saturation conduction, and current collection is low level very, through triode Q3 penetrate with, it launches very 0V, and buzzer is sounding not, because the energising of bulb short time is not luminous immediately, therefore bulb has electric current only to keep 10ms during the self check, and bulb also fails to light.Otherwise, during abnormal conditions, the bulb no current flows through, and then resistance R 3 two ends do not have potential difference (mean if continue the power failure bulb and do not work), and triode Q3 launches very 13.3V, and the thyristor Q2 control utmost point is high level at this moment, thyristor Q2 conducting, buzzer sends chimes of doom, presses the normally closed button of S1 when thyristor Q2 control utmost point low level, thyristor Q2 anode is ended less than holding current to the electric current of negative electrode, and buzzer stops to report to the police.Civil power continues to have a power failure and has a power failure as the self check simulation, and normal condition is luminous because bulb DS1 continues to have electric current, plays the effect of emergency lighting.
The present invention has a power failure by simulation, whether timer-controlled self-inspection judges that can the blackout period emergency light play the effect of illumination, have electric current to judge whether emergency light is normal by detecting bulb during the self check, because the energising of bulb short time is not bright at once, can avoid the self check phase the bright phenomenon of bulb to occur like this.
Most preferred embodiment described above only is that the present invention is set forth and illustrates, but is not limited to disclosed any concrete form, and it is possible carrying out many modifications and variations.
