Description

Universal fast electronic starter for fluorescent

The utility model relates to a kind of daylight lamp glow starting device.

At present the starter for fluorescent that generally uses is still based on the neon starter, and this starter is except simple in structure, the shortcoming of beyond price is low, have that starting time is long, the life-span is short, the low temperature low-voltage can not glow starting fluorescent lamp.In order to solve these drawbacks, be seen in patent announcement just like solid-state starter of Chinese patent 91220632.2 fluorescent lamps and 92209921.9 electronic starter for fluorescent lamp, the circuit of the inside adopts one-way SCR to make starter switch, but the SCR control terminal circuit influences because of being subjected to the rectifier for daylight lamp parameter matching, can not be applicable to 3W～40W fluorescent lamp gamut, use to be subjected to certain restriction.The electronic starter for fluorescent lamp that also has has adopted capacitance voltage-multiplying, with the voltage more than the twice (440V) glow starting fluorescent lamp, though this high voltage can the fast starting fluorescent lamp, violates fluorescent lamp preheating starter technical conditions, thereby happen occasionally and burn the phenomenon of fluorescent tube.

The purpose of this utility model is the defective that will overcome neon starter, controllable silicon starter, capacitance voltage-multiplying starter, provide a kind of unfailing performance good, energy extended day light modulation tube lifetime, can not burn fluorescent tube, the general swift electron starter of the direct glow starting fluorescent lamp pipe of energy between 150V～240V voltage.

The purpose of this utility model is achieved in that the general swift electron starter of fluorescent lamp comprises shell, circuit board, external pin with the band bottom, circuit set on the circuit board forms two paths that are connected with external pin, wherein one the tunnel is by relay normally-closed contact J1, diode D1, piezo-resistance G1, relay coil B1 series connection, and electrochemical capacitor C1 in parallel on B1 again, by relay control contacting J1 or J2, the normally opened contact control of another route relay, it is characterized in that also being connected in the said series circuit isolating diode, what connect in the path of said relay normally open contact control is a rectifier diode, also can connect by the mode of short circuit.Both that is to say and to use semi-wave DC, also can use the alternating current glow starting fluorescent lamp, but be good with the former.

Advantage of the present utility model is as follows:

1, owing to adopt the dc voltage and current starter, the half-wave current preheating fluorescent tube filament after the AC rectification meets the technical conditions of the hot starter of fluorescent tube, so can directly not burn fluorescent tube when starter.

2, adopt half-wave DC electric current and voltage glow starting fluorescent lamp, utilize ballast magnetic saturation self-induced e.m.f voltage, can be in the voltage range of 150V～240V direct glow starting fluorescent lamp pipe.

3, the starter control circuit is arranged in the middle of the DC circuit of being isolated by rectifier diode D1, isolating diode D2, therefore be not subjected to the influence of AC field and ballast coupling, power of lamp tube, starting circuit control is reliable, can not produce misoperation because of ectocine.

4, contour structure size is suitable for existing starter for fluorescent socket and connects, and is convenient to exchange and upgrades.

Be described further below in conjunction with embodiment and accompanying drawing thereof:

Fig. 1 is the structural representation of utility model embodiment.

Fig. 2 is circuit theory diagrams.

Fig. 3 is another embodiment circuit diagram.

Fig. 1 is the sample structure schematic diagram of the general swift electron starter of fluorescent lamp: shell 1, wiring board 2, bottom connect pin 3, be welded with rectifier diode D1, D3 on the wiring board 2, every stream diode D2, piezo-resistance G1, delay capacitor C1, electromagnetic relay B1, bottom pin 3 usefulness two eradication edge leads are connected bottom pin A, B two ends and wiring board two exits respectively.Wiring board 2 inserted in the shells 1 and cover pin bottom 3 get final product.

Dotted line is common fluorescent tube T outward in the circuit diagram of Fig. 2, ballast S, K switch, in the dotted line is the schematic circuit of the general swift electron starter of the utility model fluorescent lamp: rectifier diode D1 one end is connected with backplane pin (3) A end by electromagnetic relay normally-closed contact J1, the other end of diode D1 and piezo-resistance W1, electromagnetic relay B1 coil, isolating diode D2 is cascaded, time-delay electrochemical capacitor C1 two ends and electromagnetic relay B1 coil two ends are connected in parallel, and the end of isolating diode D2 one end and rectifier diode D3 is connected and links to each other with backplane pin (3) B end.The other end of rectifier diode D3 connects electromagnetic relay normally opened contact J2, and the general tie point of electromagnetic relay links to each other with the end of backplane pin (3) B.

The embodiment that Fig. 3 represents is to have omitted D3 among Fig. 2 and use direct-connected situation instead on the passage of J2.In addition, in order further to improve stability, also and a voltage-stabiliser tube W arranged at the electromagnetic relay B1 of Fig. 1, Fig. 2 coil two ends.

The course of work of the present utility model is as follows: starter is inserted common starter for fluorescent socket, after the energized K switch, alternating voltage becomes direct voltage by lead along the bottom pin after the contact of electromagnetic relay B1 J1 arrives rectifier diode, when direct voltage during greater than the piezo-resistance pressure limiting, the piezo-resistance conducting, the piezoelectricity that transfinites flows to electrochemical capacitor C1 and charges, after finishing, electrochemical capacitor C1 charging flows to the discharge of electromagnetic relay B1 solenoid with the piezoelectricity that transfinites simultaneously, electromagnetic relay B1 work, J2 is shifted to by J1 in the contact, at this moment alternating voltage is shifted to rectifier diode D3 by electromagnetic relay B1 contact J2, give by after giving the daylight filament pre-heating and that ballast is entered is saturated through the half-wave voltage electric current after the rectifier diode D3 rectification, the ballast two ends produce a self-induced e.m.f voltage that raises gradually soon, when this self-induced e.m.f voltage that raises gradually reaches certain value, fluorescent tube will starter, fluorescent tube internal resistance behind the starter reduces, the supply voltage major part is fallen on ballast, starter base pin both end voltage reduces, when electromagnetic relay B1 solenoid discharge off, electromagnetic relay B1 shifts to J1 by J2 in the contact, alternating voltage becomes direct voltage through the contact of electromagnetic relay B1 J1 by rectifier diode, when direct voltage during less than the piezo-resistance pressure limiting, not conducting of piezo-resistance, electromagnetic relay B1 does not work, when fluorescent lamp does not also have starter, direct voltage is during greater than the piezo-resistance pressure limiting, piezo-resistance is conducting once more, make electromagnetic relay B1 work again, repeat the daylight lamp glow starting process, up to daylight lamp glow starting for this reason, whole process when 240V less than 1 second, when 150V less than 4 seconds.Therefore, use the general fast starter of this fluorescent lamp except energy fast starting fluorescent lamp, fluorescent lamp is increased the service life more than one times, be specially adapted to the lower power supply area of supply voltage.
