Glow starters are commonly used to start discharge lamps, such as fluorescent lamps. However, glow starters have the disadvantage that they require several seconds to start. For this reason, rapid start type ballasts have been put into practical use that can shorten the time required for starting. However, the fluorescent lamp used for this needs to have a special structure. Further, such a rapid start type ballast is large and expensive. For this reason, various types of instant-start rotors have been proposed that use semiconductor elements and have characteristics that replace glow starters. However, the current situation is that all of these instant start starters are expensive and their reliability is still not high enough.

On the other hand, in recent years, from the perspective of energy saving, in place of low-efficiency incandescent light bulbs, fluorescent lamps with essentially high efficiency have been miniaturized and have a single-cap structure, so-called light bulb-shaped fluorescent lamps (for example, Japanese Patent Laid-Open No. 54 −
147672) has been announced. Since all of these fluorescent lamps use a glow starter as a starter, the time required to start them is significantly slower than that of an incandescent lamp, and they may be difficult to use depending on the purpose. Therefore, it is of great significance to use an instant starter in such a light bulb-shaped fluorescent lamp. However, the instant start starters that have already been announced are still expensive and have low reliability, making them difficult to put into practical use.

An object of the present invention is to provide an inexpensive discharge lamp starting device.

FIG. 1 shows a circuit configuration of a discharge lamp starting device according to the present invention. In the figure, the DC discharge lamp DL has one preheated hot cathode K and at least one anode A. This kind of DC discharge lamp
As a DL, there is a DC-operated single-capped fluorescent lamp disclosed in the above-mentioned Japanese Patent Laid-Open No. 147672/1983. A DC output end of a full-wave rectifier circuit constituted by diodes DB1 to DB4 is connected between the anode A and the hot cathode K of the DC discharge lamp DL. The AC input terminal of this full-wave rectifier circuit and the AC power supply
A current limiting element made of a chiyoke L is connected between the input terminal of V1 and the input terminal of V1 . Furthermore, a DC multiplier circuit is constructed by diodes DB1, D1 and small capacitance capacitors C1 , C2 . Also,
The diodes DB 2 , DB 4 and the switch element Q constitute a preheating circuit for the hot cathode K. That is, the hot cathode K is connected in series with the switch element Q and further connected in parallel with the diode DB 2 to form a preheating circuit. Here, the switch element Q has a characteristic that it self-breaks down and becomes conductive when the applied voltage is higher than the discharge voltage value of the discharge lamp DL and lower than the peak value of the AC power source V1 . As such a switch element Q, SSS (Symmetrical
Silicon Switch Device). The above-mentioned DC multiplier circuit is constructed by sharing the diode DB1 that constitutes the full-wave rectifier circuit. Therefore, the full-wave rectifier circuit is basically composed of the diodes DB 1 to DB 4 as described above, but the diode D 1 is further added. That is, the full-wave rectifier circuit is actually composed of diodes DB 1 to DB 4 and diode D 1 . The DC multiplier circuit includes a series circuit consisting of a diode DB 1 and a diode D 1 , a small capacitor C 1 connected between the midpoint of this series circuit and one terminal of the AC power supply V 1 , It is composed of a small capacitor C2 connected in parallel to this series circuit.

Next, the operation of the discharge lamp starting device described above will be described. AC power applied to the AC power input terminal
When the voltage of V 1 has the polarity shown in the figure, a current flows from the AC power supply V 1 , the chain yoke L, the diode DB 1 , the capacitor C 1 , and the AC power supply V 1 to the closed circuit. As a result, capacitor C 1 is charged to the peak value of the voltage of AC power source V 1 . Then, when the voltage of AC power supply V 1 becomes the opposite polarity as shown, the AC power supply V 1 capacitor
A current flows through a closed circuit consisting of C 1 , diode D 1 , capacitor C 2 , choke L, and AC power source V 1 . As a result, the capacitor C2 is charged to a voltage higher than the voltage value of the AC power supply V1 . On the other hand, the voltage of the AC power supply V 1 is also applied to the switch element Q constituting the preheating circuit.
A closed circuit consisting of a diode DB 4 , a choke L, and an AC power source V 1 is formed to apply the voltage. Therefore, as described above, the switch element Q becomes conductive at a predetermined voltage value. As a result, a current flows through the above-mentioned closed circuit and heats the hot cathode K. Next, when the voltage of the AC power source V 1 becomes the polarity shown in the figure again, the voltage obtained by adding the voltage of the AC power source V 1 and the charging voltage of the capacitor C 2 will be applied to the anode A and the hot cathode K of the discharge lamp DL. It will be applied between Therefore, the discharge lamp DL starts discharging and lights up. The above-mentioned boosting mechanism is implemented by a DC multiplier circuit. This DC multiplier circuit is also called a Kotsukucroft circuit.

In other words, when using a glow starter like a conventional starter, it takes several seconds to generate the starting voltage after the power is turned on, but with the starting device of the present invention, the starting voltage is applied immediately, so it takes only 1 second. Can be started in less time.

Thus, the discharge lamp starting device according to the present invention has five
It consists of 2 diodes, 2 small capacity capacitors, and 1 switch element. Therefore,
The number of parts used is extremely small compared to previously proposed starting devices. Moreover, since the starting device of the present invention can be constructed using only parts that are likely to have high reliability, the starting device can be made highly reliable. Furthermore, when lighting a DC discharge lamp using alternating current, a full-wave rectifier circuit is originally required. It also requires a small capacitor to prevent noise. In other words, in order to shorten the starting time, only one diode, one small capacitor, and one switch element are newly required. That is, the starting device of the present invention is very inexpensive.

FIG. 2 shows a circuit configuration of another embodiment according to the present invention. In this embodiment, a DC series circuit consisting of a capacitor C and a choke L is used as the current limiting element. The inductance value of the yoke L may be sufficiently small since it is sufficient to prevent the high frequency current from returning to the AC power source V1 . Since the current limiting element is mainly capacitor C, a diode is installed in the preheating circuit to convert the preheating current into alternating current.
D 2 and D 3 are further added. The discharge lamp DL, full-wave rectifier circuit, and DC multiplier circuit are exactly the same as those in the embodiment shown in FIG.

In addition to the features of the embodiment shown in FIG. 1, the present embodiment has the following features. That is, in the case of a current limiting element that is essentially a capacitor, when a glow starter is used, there is no inductance induced voltage due to current interruption, and a high voltage for starting cannot be obtained. On the other hand, since the starting device of this embodiment does not utilize the kick voltage caused by current interruption of the inductance, it is possible to sufficiently start the discharge lamp even if a capacitor is used as the current limiting element.
