Described bulb fixture 9 is hold-down screws, when bulb by after when being assemblied on the circuit board module forward, it is fixing with the rear end seat 12 of bulb that described hold-down screw passes circuit board module 11 after by forward direction.
Above-mentioned circuit board module can only be a trigger, also can comprise trigger and ballast.In the previous case, what said power was transmitted can be that (but being not limited to) frequency is 100Hz～800Hz, and voltage is the square wave alternating-current of hundreds of volts; Under latter event, what said power was transmitted can be (but being not limited to) 12V direct current.
Describe the operation principle of gas-discharge lamp of the present utility model, ballast and starter below in detail:
Integral structure is divided into three parts: one, front stage circuits: the input low-voltage DC flows through that the higher-order of oscillation, transformer boost, output one high voltage direct current behind the rectifying and wave-filtering; Two, late-class circuit: after the back grade vibrates filtering again, promptly obtain a square wave alternating-current from the direct current of front stage circuits output; Three, behind many voltage multiplying rectifiers,, after transformer coupled boosting, light the starter part of gas-discharge lamp work by discharge tube and the elementary effect of high-tension transformer.
Prime partly is a DC/DC conversion process, comprise the electric source filter circuit that is connected with circuit successively, input voltage sample circuit, pulse width control circuit, high-frequency oscillating circuits, rectifier filter circuit, also have output voltage, current sampling circuit, the output of its input and rectifier filter circuit joins, and the input of its output and pulse width control circuit joins.
The electric source filter circuit effect is to carrying out smothing filtering from 12V dc source or spike disturbing pulse, and delivery quality is direct current preferably.One prevents that input circuit from scurrying into noise, and it two suppresses noise that Switching Power Supply produces and feed back to input.
Pulse width control circuit comprises successively prime control module, a FET of an exportable high-frequency impulse control signal that links to each other with circuit, a transformer.Described prime control module comprises pulse control unit and power integral unit.
Output voltage, current sampling circuit, comprise a sample resistance, because in the switching tube, there be certain relation in grid level drive current with the output of leakage level, the variation of grid level input current has also been reacted in the variation of leaking the level electric current, just obtains a voltage signal that can compare by sample resistance.To send into the power integral unit after the sampling of prime field pipe leakage level output current signal, while prime output voltage sampled signal is the ingoing power integral unit also.By to output current and output voltage Integral Processing, can obtain reflecting the information of power output.This information is delivered to pulse control unit, and pulse control unit is exported by the driving pin of control module according to the information regulating impulse signal of power output again, thereby controls the break-make of prime FET, plays the purpose of power control.
The MOSFET power field effect pipe is a unijunction type device, by majority carrier conduction, does not have carrier to accumulate and time delay of producing, and switching speed is fast, and switch time is short, the conducting of its source electrode and drain electrode with end the control that is subjected to signal.By the operating frequency of the external resistance of oscillator in the prime control module, capacitance control prime field pipe, just make also to obtain high-frequency pulse current in the primary coil of transformer that the coupling by secondary coil is transferred to late-class circuit with electric energy.
The prime control module also limits according to current sampling information the electric current in the main circuit, if the current sampling value greater than the territory that sets, then the overcurrent comparator is exported a high level signal, forces pulsewidth to be turn-offed, thus the inversion process stops, and realizes overcurrent protection function.
Late-class circuit comprises the back level control module that connects with circuit successively, full-bridge circuit.A back grade control module provides 4 the road and drives signals, control back level FET (comprising first FET, second FET, the 3rd FET, the 4th FET) break-make, thus make the variation of electric current realization from the direct current to the ac square wave.Wherein the conducting simultaneously of first FET and the 3rd FET with end, the conducting simultaneously of second FET and the 4th FET with end, the two pairs of pipe alternate conduction with end, so direct current has just become square wave alternating-current.But after filter capacitor filtering, obtain the intact alternating current of the bright use of supplied gas discharge lamps bubble point.
Behind many voltage multiplying rectifiers, by the effect of high-tension transformer primary coil and the discharge tube that links to each other with primary coil, make gas-discharge lamp generation glow discharge again, process that gas-discharge lamp lights that Here it is from the inferior grade coupled high voltage of high-tension transformer.But after the arc through, because the change of bulb voltage characteristic, the voltage that requires to be added on the bulb must be got back on the normal arc discharge voltage at once, is generally 85V voltage, so control the stabling current of lighting a lamp by current-limiting resistance.
The utility model discloses the incorporate high-intensity gas discharge lamp of bulb and wiring board; though only use the annexation in the middle of two embodiment bright lamp bubbles and circuit board module and the reflector, any with circuit board module and bulb line direct connection relational and the HID lamp of circuit board module and reflector annexation all within protection domain of the present utility model.
