The pierce circuit is made up of capacitor charge and discharge circuit, comparison circuit and frequency dividing circuit.
The utility model has the advantages that:Simple structure, can all-around mobile shadowless lamp head, it is ensured that the illumination range of shadowless lamp It is maximum with illumination radiation angle, greatly subtract umbra light, eliminated impact of the umbra to performing the operation to the full extent.
Description of the drawings
This utility model is described in detail with reference to embodiment and accompanying drawing, wherein:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the circuit diagram of drive circuit of the present utility model.
Fig. 3 is the pierce circuit of Fig. 2.
Specific embodiment
Specific embodiment of the present utility model is expanded on further below in conjunction with the accompanying drawings:
As shown in Figure 1, 2, a kind of mobile shadowless lamp with drive circuit, including a slide rail 1, and set on the slide rail There is a fixed seat 2, and the fixed seat can be slided along the slide rail, and a fixed fix bar 3 in the fixed seat, and it is described solid One first fix bar is fixed in fixed pole, and the other end of first fix bar connects one second fix bar, and described second consolidates The other end of fixed pole connects one or three flap LED surgery lamps, and the fix bar is further fixed on the 3rd fix bar, and the described 3rd fixes The other end of bar is connected one the 4th fix bar, and the other end of the 4th fix bar connects one or four flap LED surgery lamps.Institute State the first fix bar and the 3rd fix bar can be rotated around the fix bar, and second fix bar can be around which with described The junction rotation of one fix bar, and the 4th fix bar can be around its junction rotation with the 3rd fix bar.It is described First fix bar is vertical with second fix bar, and the 3rd fix bar is vertical with the 4th fix bar, and described Three fix bars are parallel with first fix bar, and the 4th fix bar is parallel with the 3rd fix bar.
The three flaps LED surgery lamp and the four flaps LED surgery lamp include a LED, and the LED includes One drive circuit, and the drive circuit includes wireless switching processing module, oscillator module, reference voltage module, logic electricity Road control module, comparator module, on-off circuit module, low pressure detection module, digital regulation resistance module, synchronized update plus-minus skill Art module and Drive Module, drive circuit make electricity by the way of Analog Electronics Technique is combined with Digital Electronic Technique Road has the ripple output voltage of very little, obtains output of good performance.
As shown in figure 3, pierce circuit is made up of capacitor charge and discharge circuit, comparison circuit and frequency dividing circuit, its principle is: When comparator is output as low level, left side metal-oxide-semiconductor series circuit charging circuit conducting, discharge circuit cut-off are filled to electric capacity Electricity, when capacitance voltage is higher than resistance branch voltage, comparator output high level, metal-oxide-semiconductor conducting now in parallel with a resistor and Internal resistance is less than resistance connected in parallel, and comparator Vin- input terminal voltages are less than capacitance voltage and provide certain for discharge circuit Time remaining, now charging circuit cut-off, discharge circuit begin to turn on, and circuit discharging makes capacitance voltage less than Vin- inputs electricity Pressure, discharge circuit cut-off, metal-oxide-semiconductor cut-off in parallel with a resistor, charging circuit conducting enable the circuitry to persistent oscillation.In principle In figure, as charge-discharge velocity is different, the pulse duty factor of circuit output is different, therefore is amplified using frequency dividing circuit adjustment Device pulse duty factor and driving force is improved, spacing output circuit reduces the impact to its performance.
Circuit is using to capacitor charge and discharge, therefore the adjustment to frequency of oscillation need to only adjust its charging and discharging currents size, i.e., Adjust the parameters such as the breadth length ratio of metal-oxide-semiconductor, the comparison voltage of gate source voltage, capacitance size or Vin- ends and be capable of achieving frequency adjustment.Figure Middle employing metal-oxide-semiconductor tool in parallel with a resistor plays a very important role, if not having this control circuit, oscillating circuit can find one and put down Weighing apparatus point makes circuit keep constant output, it is impossible to realize vibration.The charging speed of circuit is understood by comparator output waveform dutycycle Degree is less than its velocity of discharge.
Preferred embodiment of the present utility model is the foregoing is only, it is not to limit this utility model, all at this Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in this utility model Protection domain within.
