Embodiment
This exposure book provides a kind of fluorescent lamp fault detect auto-power-off device that is installed in fluorescent start circuit, it can be by whether stablizing to judge by the electric current of fluorescent tube whether fluorescent tube or starter damage in one scheduled time of detecting, to avoid continuing flicker because of the fluorescent tube using for a long time or the life-span is about to exhaust, cause the people's health under this blinking light to produce uncomfortable.Below, describe a preferred embodiment that coordinates appended graphic demonstration in detail feature of the present utility model and effect.
Please refer to Fig. 1, is the circuit framework figure of the sight lamp start-up circuit of the fluorescent lamp fault detect auto-power-off device of application the utility model preferred embodiment.As shown in the figure, described fluorescent lamp fault detect auto-power-off device 100 is connected in a fluorescent lamp module 1, comprises a switch element 2, a current sense unit 3 and a control unit 4.Particularly, fluorescent lamp module 1 comprises fluorescent tube and starter (figure does not show); One end of fluorescent lamp module 1 is connected to a civil power 5 and the other end is connected to current sense unit 3, and meaning is that fluorescent lamp module 1 is to be series between civil power 5 and current sense unit 3.By this, civil power 5 can be supplied with the power supply that fluorescent tube starts, and after fluorescent tube is lighted, current sense unit 3 detects the electric current on tandem paths.In the present embodiment, current sense unit 3 can be current/voltage monitoring circuit (current/power monitor), but is not restricted to this.Switch element 2 comprises a switch portion 21 and a coil portion 22, and wherein coil portion 22 is connected to control unit 4 through one drive circuit 6; Switch portion 21 has one first controlled end 211 and one second controlled end 212, the first controlled ends 211 and is connected to equally 212 of civil power 5, the second controlled ends and is connected to current sense unit 3.In the present embodiment, switch element 2 can be a relay, but is not restricted to this.
Control unit 4 can be a microcontroller (as the PIC10F220 of microchip company), but the utility model is non-as limit.Control unit 4 has an input 41 and an output 42, and wherein input 41 is connected to current sense unit 3, and output 42 is connected to drive circuit 6.In the time that current sense unit 3 detects the electric current by fluorescent lamp module 1, an analog signal of this electric current is to control unit 4 relatively in output immediately, and control unit 4 can convert this analog signal to digital signal, and then judge whether electric current is stablized.
In more detail, above-mentioned judgment mode is the stability of detecting this analog signal within a scheduled time; If stable, 3 of current sense unit continue this analog signal of detecting, and export a high levle signal to switch element 2, and in process, drive circuit 6 can amplify this high levle signal.So, the coil portion 22 of switch element 2 can supply current flowing to produce galvanomagnetic effect, and switch portion 21 can be subject to the magnetic effect of coil portion 22 and be closure state, and then the fluorescent tube of civil power 5 sustainable supply fluorescent lamp modules 1 starts required power supply.If unstable, a low level signal is exported immediately to switch element 2 in current sense unit 3, to interrupt the current flowing of coil portion 22, now the switch portion 21 of switch element 2 is off-state because coil portion 22 stops magnetic effect, to cut off linking between civil power 5 and fluorescent lamp module 1.
Remark additionally, in fluorescent lamp module 1 is opened, can there is flicker according to fluorescent tube and interrupt in the analog signal that current sense unit 3 transmits, and the interruption times that so control unit 4 detects and time are to set in advance; Accordingly, as long as the interruption times of analog signal is no more than pre-determined number within a scheduled time, control unit 4 just can not ordered switch element 2 cut-offing instructions.
Drive circuit 6 comprises a pair of polarity junction transistor npn npn 61 and a protective resistance 62, protective resistance 62 wherein can current limliting with protection bipolarity junction transistor npn npn 61; Bipolarity junction transistor npn npn 61 has an emitter-base bandgap grading (Emitter) 611, a base stage junction (Base) 612 and a collector (Collector) 613; emitter-base bandgap grading 611 is connected to the coil portion 22 of relay; base stage junction 612 is connected with the output 42 of control unit 4 via protective resistance 62, and collector 613 couples an earthing potential 63.
The fluorescent lamp fault detect auto-power-off device 100 of the present embodiment can further comprise a pressurizer 7, and it can be but is not limited to rectifier diode.Pressurizer 7 is to be connected between the coil portion 22 and bipolarity junction transistor npn npn 61 of switch element, can prevent that the reaction electromotive force producing when switch element 2 is closed from impacting bipolarity junction transistor npn npn 61.
Referring to Fig. 2, is the applicating flow chart of the utility model fluorescent lamp fault detect auto-power-off device.And please coordinate with reference to figure 1, the application of described fluorescent lamp fault detect auto-power-off device comprises the following steps:
First as shown in square S1, a fluorescent lamp module 1 is connected to respectively to a civil power 5 and an above-mentioned fluorescent lamp fault detect auto-power-off device 100; Follow as shown in square S2, current sense unit 3 continues detecting by the electric current of fluorescent lamp module 1, and an analog signal of relative this electric current of output is to control unit 4; Then as shown in square S3, control unit 4 judges that within a scheduled time whether the analog signal of this electric current is stable relatively;
If so, as shown in square S4, control unit 4 is exported a high levle signal to switch element 2, makes switch element 2 continue conducting fluorescent lamp module 1 and civil power 5; If not,, as shown in square S5, control unit 4 is exported a low level signal to switch element 2, makes switch element 2 disconnect the link between fluorescent lamp module 1 and civil power 5.
Via the above, the utility model and existing structure can produce following beneficial effect in comparison:
Fluorescent lamp fault detect auto-power-off device of the present utility model can detecting real-time fluorescent tube or starter whether damage, once fluorescent tube, flicker occurring can be with by its power-off, to reduce energy resource consumption, and avoid continuing because of the fluorescent tube using for a long time or the life-span is about to exhaust light, the noise jamming that flicker produces.
2. above-mentioned fluorescent lamp fault detect auto-power-off device is by detecting in a scheduled time to judge by the current stability of fluorescent tube whether fluorescent tube or starter damage, the facts that the naturally of short duration flicker can avoid that erroneous judgement fluorescent tube occurs and just lighted time is damage.
Though the utility model discloses in preferred embodiment mode; so it is not in order to limit the utility model; anyly have the knack of this skill personage; not departing from the spirit and scope of the utility model; when doing various changes and modification, therefore the protection range of the utility model when depending on after the attached claim person of defining be as the criterion.
