Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 3 a shows a kind of lighting apparatus 1000 according to the utility model first embodiment, and wherein, energy saver 500 is connected between the supply module 100 and lighting module 200 of lighting apparatus.Supply module 100 is used to lighting module 200 that power supply is provided, for example the alternating current of 380V, 220V or 110V.Lighting module 200 comprises ballast 210, building-out capacitor 220, and trigger 230 and light source 240, wherein building-out capacitor 220, and trigger 230 and light emitting source 240 are parallel with one another, and ballast 210 is connected between building-out capacitor 220 and the trigger 230.
Under the normal condition, first end 331 and second end 332 of first switch 330 are connected, and first end 331 disconnects mutually with the 3rd end 333.Be appreciated that this moment, additional ballast 310 is in short-circuit condition, and ancillary relief electric capacity 320 is in off state, that is, energy saver 500 is not worked.Therefore, lighting module is in the full power operation state, and illumination intensity is the highest.
When not needing floodlighting, first end 331 and the 3rd end 333 of first switch 330 can be connected, and first end 331 disconnects mutually with second end 332, at this moment, 320 chargings of ancillary relief capacitor.Because additional ballast 310 is connected between ancillary relief electric capacity 320 and the building-out capacitor 220, and connect mutually with ballast 210, additional ballast 310 plays the effect of step-down current limliting, this makes the voltage at light source 240 two ends reduce, thereby lighting module is in and falls the power operating state, and illumination intensity reduces.Because additional ballast 310 self has ancillary relief electric capacity 320, therefore, even falling the power operating state, lighting apparatus 1000 is the power factor of correcting circuit well also, thereby improves luminous efficiency.
Refer again to accompanying drawing 3a, one of ordinary skill in the art will appreciate that, under the full power operation state, additional ballast 310 is by first switch, 330 short circuits, when the needs transfer power, when the moving head of first switch 330 leaves moment of second end 332, the effect of step-down has been realized in the additional ballast 310 cut-in operation loop of just connecting.That is to say that in the moment that can not occur cutting off the power supply, therefore, the energy saver in employing the utility model can be avoided the generation of electric arc disruption well in the transfer process of first switch 330.Correspondingly, the requirement to electronic switch also just reduces.
Fig. 3 b has shown the circuit diagram according to the energy saver of another preferred implementation of the present utility model.Compare with the energy saver that shows among Fig. 3 a, the energy-saving module 300 of the energy saver 500 that shows among Fig. 3 b further comprises resistance 350, and second switch 340.Resistance 350 and second switch 340 are connected mutually, and this series arm is connected in parallel on the two ends of additional ballast 310.When normal (high power) operation, first end 331 and second end 332 of first switch 330 are connected second switch 340 closures.Be appreciated that because first end 331 and second end 332 of first switch 330 is connected resistance 350 is the same with additional ballast 310, also be in short-circuit condition and do not work.
When not needing floodlighting, first switch 330 at first is triggered so that first end 331 and the 3rd end 333 are communicated with, and second switch 340 (for example, 5 seconds) in a period of time still is kept closed.In this section transitional period, the electric current that is provided by supply module 110 flows into lighting module 200 after by the parallel branch of being made up of resistance 350 and additional ballast 310.After this section time-delay, second switch 340 is disconnected, and resistance 350 is opened circuit and do not work, and at this moment, circuit is in the aforesaid power operating state of falling.It will be appreciated by those skilled in the art that, adopt this mode, in the moment of first switch, 330 conversions, even cause the momentary interruption of additional ballast 310 owing to the electric current that adds ballast 310 two ends can not suddenly change, because additional ballast 310 two ends are in parallel resistance 350, therefore lighting module momentary power failure phenomenon can not occur, thereby has avoided the generation of electric arc disruption further.
As shown in Figure 4, according to another execution mode of the present utility model, energy saver 500 may further include the control module 400 that is used for the control switch break-make.Control module 400 is connected between supply module 100 and the energy-saving module 300.As shown in the figure, control module 400 comprises power circuit 410 and timing circuit 420.Wherein, power circuit 410 provides power supply for timing circuit 420, and timing circuit 420 provides switching signal for first switch 330.
Preferably, can be according to power circuit 410 of the present utility model by transformer 411, full-wave rectifying circuit 412 and voltage regulator chip 413 are composed in series.
