放電灯点灯装置が使用される。Generally, in order to light a DC discharge lamp, such as a xenon short arc lamp, a DC discharge lamp lighting device commonly called a ballast is used.

接続される。In the past, this ballast had a major drawback of being heavy, but recently, ultra-compact and lightweight ballasts that employ a semiconductor element opening/closing control system have been developed. An example of the design of the ballast that employs the current semiconductor element opening/closing control method will be explained with reference to FIG. 1.
In addition, an inverter constituted by a transformer T1 is connected, one 2A of the two secondary side output parts of the transformer TI is connected to a rectifier DI, and a current detection element following the rectifier DI is connected to the negative side of the rectifier DI. 3, a smoothing circuit 4 consisting of a high frequency choke coil LI and a capacitor C is connected, and its positive output terminal is connected to the positive side of the discharge lamp 6 via the starter 5, and the rental output terminal is connected to the discharge lamp 6.

電圧またはそれに近いものとされる。Here, since the inverter 10 outputs high frequency alternating current of 20 to 100 KHz, a choke coil suitable for high frequencies is used as the smoothing circuit 4. The discharge lamp 6 is
During stable lighting, the inverter 10 and rectifier D
1. Since the main circuit composed of the smoothing circuit 4 lights up the light, in order to design this main circuit most economically,
The output voltage of the main circuit during stable lighting is at or close to the rated voltage of the discharge lamp 6.

This high voltage superimposition circuit is usually composed of a transformer, a rectifier, a resistor, and a superposition capacitor, but in the example shown in FIG. A capacitor C constituting the smoothing circuit 4 is connected to one end via a series circuit of a rectifier diode ○2 and a resistor RI.
The other end of the capacitor C is connected to the positive side of the capacitor C, and the other end thereof is connected to the negative side of the capacitor C. That is, in this example,
The transformer TI is shared by the main circuit and the high voltage superimposition circuit, and the capacitor C is shared by the smoothing circuit 4 and the high voltage superimposition circuit. On the other hand, the signal from the current detection element 3 is sent as a feedback signal to a pulse width control circuit 8 comprising an error amplifier EA connected to a reference voltage source Vref and a pulse width converter PWM connected to an oscillator OSC. is,

である。When the starter 5 is activated and the discharge lamp 6 undergoes dielectric breakdown, a large amount of charge is instantly released from the capacitor C, causing a transition from the glow discharge seen at the beginning of lighting to arc discharge, and the discharge lamp 6 , after which it enters a stable lighting state.
しかしながら斯かる構成の従来の直流放電灯点灯装置に

消えが生ずることが判明した。However, it has been found that even in the conventional DC discharge lamp lighting device having such a configuration, the transition from glow discharge to arc discharge is not always achieved smoothly and reliably, and so-called extinction still occurs.

た。To explain this, the lamp voltage VL at the time of starting the discharge lamp 6 is as shown in FIG. By discharging, the superimposed voltage V^ is lowered, and as a result, the lamp current IL rises rapidly from time t to peak current IP at a time immediately after time t, as shown at the beginning of Figure 2. and then decreases. When the time reaches the time, the lamp voltage VL becomes about 1.5 to 3 times higher than the rated lamp voltage VB, and the lamp current IL becomes 4 times higher than the rated lamp current IB. Then, the time e.g.
Only then does the discharge lamp 6 enter a stable lighting state according to its rating. During the period from time t2 to W, so-called extinguishing occurs and the discharge lamp 6 is turned off. After examining various causes of this phenomenon, it was concluded that it is because the peak current IP appears too early.

とを目的とする。That is, as mentioned above, the peak current I is added to the lamp current IL.
P appears at time t immediately after activation of the starter 5, and at this time the lamp voltage VL is high enough to cause only glow discharge, and the cathode of the discharge lamp 6 is also sufficiently heated. Therefore, the effect of the peak current IP flowing is only to increase the area of the glow discharge generation region where the current density is constant on the surface of the cathode, which is necessary for transition to arc discharge. It remains uncontributed to the generation of arc formations. In other words, in order to facilitate the transition from glow-fin to arc discharge, it is not enough to simply supply a large amount of charge from the high voltage superimposition circuit to the discharge lamp at the initial stage of startup, as in the past. The ignitability of the discharge lamp is not always good at this time, and the discharge lamp cannot be lit reliably unless the timing at which the peak current IP appears is taken into consideration. The present invention relates to an improvement of a DC discharge lamp lighting device that employs a semiconductor element opening/closing control system, and facilitates the transition from glow discharge to arc discharge in the discharge lamp when starting the lighting of the DC discharge lamp. An object of the present invention is to provide a DC discharge lamp lighting device that can reliably light a discharge lamp.

In the present invention, as shown in FIG. 3, for example, a DC power supply 1 and an inverter 10 configured in the same manner as in FIG.
A smoothing circuit 4 comprising semiconductor switching elements TR1, TR2, a transformer T1, a rectifier D1, a current detection element 3, a high frequency choke coil LI and a capacitor C.
, a high voltage superimposition circuit, a pulse width control circuit 8, and a drive circuit 9, the positive output side of the capacitor C in the smoothing circuit 4 is connected to the positive side of the discharge lamp 6 via the starter 5, and the The negative output side of C is connected to the negative side of the discharge lamp 6 via the low frequency choke coil L2.

兼ねているが、平滑回路４を構成するコンデンサを兼用

るようにしてもよい。In this example, the capacitor C is a capacitor that constitutes the smoothing circuit 4 and also serves as a capacitor for high voltage superimposition, but it does not also serve as a capacitor that constitutes the smoothing circuit 4, but is separately used for high voltage superimposition. A superimposition capacitor may be provided.

なる。Since the present invention has the above-described configuration, when the starter 5 is activated, the lamp voltage VL is changed from the superimposed voltage VA of the capacitor C charged by the high voltage superimposing circuit, as shown in FIG. 4A. However, as shown in Figure 4, the lamp current IL is limited to a value slightly higher than the rated current 18 by the low frequency choke coil L2, and then gradually increases to reach the peak current IP at time 5. will reach .

したものである。In other words, unlike the case where the peak current IP flows during glow discharge when the lamp voltage VL is sufficiently high, by suppressing the lamp current IL to a relatively small value when the lamp voltage VL is sufficiently high, the minute tip of the discharge lamp 6 A device that heats the cathode by generating a glow discharge only in the area, and extends the heating time while keeping the peak value of the peak current IP low, thereby efficiently forming an arc neck point at the minute tip of the cathode. It is. As a result, the discharge lamp 6 smoothly transitions from the glow discharge state to the arc discharge state after time t, as shown in FIG. come to enter the state. In summary, in the present invention, by controlling the timing of the appearance of the peak current IP due to the discharge of charge from the capacitor C using a low frequency choke coil, conditions are created in which an arc dark spot is easily formed, and thus the discharge lamp This facilitates the transition from glow discharge to arc discharge at the initial stage of lighting startup.

It is sufficient to have frequency characteristics that can cause a delay of rsec or more.

流放電灯点灯装置を提供することができる。Specifically, this diode ○3 may be connected at the connection point between the diode D3 and the discharge lamp 6 so that both the connection terminals of the diode D3 and the discharge lamp 6 have the same polarity. In the case of FIG. 5, the cathode side of the diode D3 and the cathode side of the discharge lamp 6 are connected, and the anode side of the diode D3 and the negative side of the capacitor C are connected. By adding the diode ○3 in this way, the lighting performance at the time of starting the lighting becomes even better.
That is, when the diode D3 is not added, the discharge lamp 6, the low frequency choke coil L2, and the capacitor C form a so-called RLC circuit, so the lamp current IL oscillates, and this oscillation normally occurs. The larger the inductance of the coil, the larger the inductance. As a result, a situation occurs in which the lamp current IL becomes small, and at this time, there remains a possibility that flashing and extinguishing may occur. However, if the diode D3 is added, the lamp current IL will not oscillate due to the diode D3, thereby preventing the lamp from going out. In the example shown in FIG. 3, this low frequency choke coil L2 is inserted between the negative side of the capacitor C and the discharge lamp 6, but instead of this, or in addition to this, the positive side of the capacitor C Even if it is inserted between the side and the discharge lamp 6, exactly the same effect can be obtained. As described above, according to the present invention, with an extremely simple configuration, it is possible to easily transition from glow discharge to arc fin discharge at the time of starting the discharge lamp,
It is possible to provide a DC discharge lamp lighting device that can reliably light a discharge lamp after starting the lighting.

The problem that lighting may fail is solved by a simple configuration of adding a low-frequency choke coil, and this provides the advantage of improving lighting performance.

Therefore, it does not substantially impede the miniaturization and weight reduction of the device, which are the advantages of adopting the semiconductor element opening/closing control method.
