Description of drawings
Fig. 1 is a concrete operation principle sketch map that adopts the reverse exciting topological circuit of the utility model.
Fig. 2 is a concrete employing reverse exciting topological of the utility model and makes the circuit working principle schematic of isolating with the light lotus root.
The practical implementation method:
To combine accompanying drawing that the utility model is done detailed introduction below: shown in Figure 1; The utility model mainly includes: it (can be the front and back of filter circuit 9 that an input connects civil power; Rectifier bridge 8 inputs) sampling diode 1, its output are connected in a waveform shaping circuit 2; The output of this waveform shaping circuit 2 is connected to a pulse number testing circuit 3; The output of this pulse number testing circuit 3 is connected in a pulsewidth output scanning circuit 4 again; It (is instance with a kind of common inverse-excitation type translation circuit here that this pulsewidth output scanning circuit 4 connects the drive circuit 5 of controlling bulb with the mode that changes output pulse width; Can be any other pulse-width modulation circuit during practical application), these bulb driving circuit 5 outputs are connected to bulb 10; Described waveform shaping circuit 2 and pulse number testing circuit 3 insert the electric capacity 6 of larger capacity, for example hundreds of or several thousand microfarads together with the power supply+quilt of pulsewidth output scanning circuit 4; And the power supply of control centre provides circuit to pass through diode 7 and described electric capacity 6, so that give electric capacity 6 chargings.
The utility model is built into light fixture simultaneously together with bulb driving circuit, and the course of work is: just can normal illumination as long as open or close mains switch 11 as normal use ordinary lamps usually, and civil power is through filter circuit 9 filtering; Provide bulb driving circuit 5 required energy after rectifier bridge 8 rectifications; Bulb 10 is normally lighted; Half-wave voltage signal from sampling diode 1 is shaped to the square-wave signal of 50Hz or 60Hz (frequency depends on mains frequency) by waveform shaping circuit 2, because this square-wave signal is the continuous impulse signal, stops output less than the interval of pulse so pulse number testing circuit 3 detects; And pulsewidth output scanning circuit 4 is owing to can not get the output triggering of pulse number testing circuit 3; So scanning process can't begin, this circuit will maintain the original state, and light does not have any variation.
When needs use dimming function; The user only need be closed fast under the state of electric power starting and driven primary power source switch 11; Civil power provides after through rectifier bridge 8 rectifications bulb driving circuit 5 required energy; Bulb 10 is lighted; And be shaped to the square-wave signal of 50Hz or 60Hz (frequency depends on mains frequency) by waveform shaping circuit 2 from the high pressure half-wave voltage signal of high-pressure sampling diode 1, because an interrupted pulse signal is exported in user's switch motion, pulse number testing circuit 3 detects this interrupted pulse signal and exports a triggering signal and give pulsewidth output scanning circuit 4 owing to this square-wave signal; Scanning circuit 4 will be narrowed down or by the narrow scanning that broadens by wide to the pulsewidth of its output, and this dynamic pulsewidth is exported to drive circuit 5; Bulb 10 brightness that are connected to it will change thereupon; When light reaches customer requirements; The user only needs the pass to drive primary power source switch 11 again; Be shaped to the low pressure square-wave signal of 50Hz or 60Hz (frequency depends on mains frequency) by waveform shaping circuit 2 from the half-wave voltage signal of high-pressure sampling diode 1; Owing to this low pressure square-wave signal is exported an interrupted pulse signal because of user's switch motion; Pulse number testing circuit 3 detects this interrupted pulse signal and exports a triggering signal and will stop the pulsewidth of its output is perhaps preserved by the narrow scanning that broadens and the width of this pulsewidth by wide narrowing down for once more pulsewidth output scanning circuit 4, scanning circuit 4, exports to bulb driving circuit 5 simultaneously; At this time bulb 10 can rest in the brightness that the user hopes, using the same method up to the user changes brightness once more.
Shown in Figure 2 is that one of the utility model specifically adopts reverse exciting topological and makes the circuit working principle schematic of isolating with the light lotus root; The difference of it and Fig. 1 is: control centre's circuit has been placed to output one side of bulb driving circuit 5; Half-wave voltage signal from diode 1 is connected to waveform shaping circuit 2 through 12 isolation of a light lotus root; And pulse number testing circuit 3 is connected to pulse width control circuit 4 through an other light lotus root 13 isolation; The benefit that this method is brought is, because control centre and load (bulb 10) are in the same side, so can create conditions for controlling bulb brightness more accurately.
The described bulb of the utility model is any luminous element, comprises but is not limited to fluorescent tube, cold-cathode tube, LED lamp string, incandescent lamp bulb, high-pressure sodium lamp, Metal halogen lamp, iodine-tungsten lamp.
In sum; The user can not use under any dimmer equipment and the situation that changes any civil power cabling and use this desk lamp with dimmer switch; Any mains switch that is connected to this lamp also is outstanding " dimmer " simultaneously; And owing to derive from same civil power from the half-wave voltage signal of diode 1, a mains switch can let the light modulation of a plurality of desk lamp with dimmer switch precise synchronization, great convenience use the user of a plurality of desk lamps with dimmer switch to use.
What particularly point out is, electric capacity 6 can let waveform shaping circuit 2 in the utility model circuit, pulse number testing circuit 3 and pulsewidth output scanning circuit 4 in user's light modulation process owing to power supply is kept the continued power to foregoing circuit by of short duration cut-out.
Other related technology of the utility model is technique known.The circuit of this area research and development engineer can implement the utility model easily on the content basis of understanding the utility model, utilize this technology, only successfully developed just can stepless dimming with mains switch LED fluorescent tube and LED bulb lamp.
