Abstract
An electronic ballast module is characterized in that the module consists of a thick film circuit consisting of eleven diodes and ten resistances and has eighteen pins. An ultraviolet lamp or a fluorescent lamp which adopts the utility model can obtain smaller volume, lower production cost, higher safety factor and convenience for installation and use.
Description
Technical field
The utility model relates to the electric ballast of a kind of uviol lamp or fluorescent lamp, refers in particular to the parts that constitute its electric ballast.
Prior art
Uviol lamp and the daylight lamp apparatus selling on the market and use roughly can be divided into two classes, the first kind is old-fashioned daylight lamp apparatus, it includes ballast and two kinds of parts of starter, and its ballast is made up of a bigger inductance element of volume, and starter and ballast are separated, so rate of breakdown height, power factor (PF) is low, and heavy, fluorescent lamp has noise when working, and the production routine complexity, be difficult for installing, progressively be eliminated; Another kind of employing be that electric ballast replaces above-mentioned ballast and starter, thereby starter need not be set, saved the space, reduced cost, noiseless during work, the flicker free phenomenon, therefore the power factor (PF) height has obtained extensive use; But for adopting this class daylight lamp apparatus of electric ballast, the parts in its circuit constitute by multiple electric elements, as diode, triode, inductance, resistance etc., when producing, its solder joint is more, and safety factor reduces relatively, and operation is also complicated; Therefore, the part components and parts with module replacement electric ballast seem very necessary.
Technical scheme
The purpose of this utility model is according to existing uviol lamp or sight lamp device, and the circuit that its part components and parts are constituted provides a kind of electric ballast module with a thick film circuit replacement.
The technical solution of the utility model is to produce like this:
See also this paper accompanying drawing 1, a kind of circuit of electronic ballast is provided, its operation principle is: form the input filtering rectification circuit by TNR, L1, C1, the high order harmonic component that is used for stoping ballast to produce feeds back to AC network, simultaneously also can prevent to invade electric ballast to the pollution of electrical network with to the interference of electronic equipment suppressing from the interference of electrical network.
Form full-wave rectifying circuit by D1-D4, C2, form Active PFC (PFC) circuit by D5-D7, C3, C4---passive harmonic current follow-up circuit, its effect are exactly to obtain the low current harmonic distortion, realize high power factor.
What its self-excited oscillation circuit adopted is voltage feed semi-bridge type inverter circuit.After electric ballast powers up, R10 flows through, the electric current of R5 is to starting capacitor C 6 chargings, be elevated to the breakover voltage value of D10 when the C6 both end voltage after, D10 avalanche breakdown, C6 then discharges by base stage-emitter of Q2, Q2 is because of the forward bias conducting, in Q2 conduction period, current path is: VDC+-C10-C9-choke (T2 is the utmost point just)-T1 primary coil L3---Q2 collector electrode---ground, the transient change of Q2 collector current is by two secondary winding L1 of T1, the L2 two ends produce an induced voltage, and the base potential of Q2 is raise, base current and collector current further increase, and this positive feedback makes Q2 enter the saturation conduction state immediately.When the Q2 conducting, starting capacitor C 6 will be by diode D13 and transistor Q2 discharge, to stop the Q2 base stage is produced further triggering, start-up circuit provides an outside instantaneous trigger signal, the foundation of oscillating circuit and keeping then by means of the coupling between the saturation transformer T1 winding---and produce positive feedback and realize.After T1 reaches capacity, induced potential in each winding is zero, and the Q2 base potential is on a declining curve, and the Q2 collector current reduces, but the induced potential of the elementary winding L 3 among the T1 will stop reducing of Q2 collector current, so the Q2 base potential descends, the Q1 base potential raises, this positive feedback makes Q2 withdraw from the saturated cut-off state that enters rapidly, 01 then by being saturation conduction by transition again, and when the Q1 saturation conduction, path of current is: Q1-T1 primary coil L3-T2 is elementary-and C9-C11-ground.When the T1 magnetic core enter saturated after, the very fast Q2 saturation conduction once more that makes again of interlock type positive feedback, Q1 then by conducting again transition for ending, so go round and begin again, Q1, Q2 take turns conducting, make that the sense of current constantly changes on the capacitor C 9 that is parallel to lamp tube ends, have caused the LC network generation series resonance that by T2 elementary and C9 etc. forms, thereby produce a high-voltage oscillation voltage at the C9 two ends and be applied on the fluorescent tube, make fluorescent tube trigger starter.
Formed the load open circuit protection circuit by D20, R12, R13, C7, D22, R11, SCR, R10 and Q3; when promptly output does not connect fluorescent tube; in about 1 time in second of energising; this protective circuit will be moved; make circuit be in the failure of oscillation state; outage such as having only to connect behind the fluorescent tube (load) energising again could startup work; form Working state checking circuit by R14, D21, C8, R15; promptly when ballast circuit is working properly; detect voltage one of two ends output; but when ballast is not worked, just there is not this voltage.
According to circuit shown in Figure 1, with 18 nodes of 11 diodes and 10 resistance, that forms with a thick film circuit replaces with 18 corresponding 18 pin of node, thereby has formed the technical solution of the utility model:
A kind of electric ballast module promptly is provided, it is characterized in that thick film circuit that it is made of 11 diodes and 10 resistance is formed, have 18 pin, corresponding one by one with node among the figure 1～18, the annexation of described 11 diodes and 10 resistance and 18 pin is:
