Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a circuit block diagram for explaining the concept of the present invention. In the figure, 11 is an AC power supply, 12 is a ballast, 13 is a first high voltage generating means, 14 is an output line of the ballast, 15 is a second high voltage generating means, 16 is a high pressure discharge lamp, and 18 is a lighting fixture. It is the main body. A metal halide lamp is most suitable as the high-pressure discharge lamp, but it can be applied to a high-pressure sodium lamp, a high-pressure mercury lamp or the like, if necessary. The ballast 12 has a discharge stabilizing element 12a, and is configured to supply the power necessary for lighting the high pressure discharge lamp from the output end via the output line 14.
The first high voltage generating means 13 may be built in the ballast 12 as shown in the figure or may be a separate body. The second high voltage generating means 15 includes a differentiating means 15a, is separated from the first high voltage generating means 13, and is disposed, for example, in the vicinity of the high pressure discharge lamp 16. In addition, 15b is a high voltage pulse generator. First and second high voltage generating means 13, 1
Although 5 may operate continuously during power-on, it can be controlled by a timer (not shown) so that it operates only for a certain period of time after power-on, if necessary. Further, the first and second high voltage generating means 1 are detected by detecting lighting of the high pressure discharge lamp.
The operation of 3 and 15 may be automatically stopped.

The ballast 12, the first high voltage generating means 13 and the second high voltage generating means 15 constitute a high pressure discharge lamp lighting device, and a high pressure discharge lamp 16 is added thereto to constitute a high pressure discharge lamp device. The lighting fixture body 1
8 is added to form a lighting device. Here, the luminaire main body includes any structure necessary for functioning as a luminaire such as a housing for accommodating a high pressure discharge lamp, a lamp socket, a light control means such as a reflector or a prism.

Next, the operation will be described with reference to FIGS. FIG. 10 is a voltage waveform diagram of each part in FIG. FIG. 11 is a composite waveform diagram of the first and second pulse voltages. When the power supply 11 is turned on, the power supply voltage indicated by V in FIG. 10 is applied to the input terminal of the ballast 12. Along with this, the secondary open circuit voltage of the ballast 12 is applied to the high pressure discharge lamp 16 via the first and second high voltage generating means 13 and 15. In this state, the high pressure discharge lamp cannot be started. However, the first high voltage generating means 13 starts its operation when the power is turned on, the first pulse voltage is generated at a predetermined phase as shown by P1 in FIG. 10, and the first pulse voltage is transmitted through the output line 14. And is applied to the high pressure discharge lamp 16 and the first high voltage generating means 15.

The first pulse voltage has a relatively low peak value, but a large time width, and therefore a large energy. The peak value is selected from 300 V to 6 KV, for example 3 KV, the time width is selected from 3 microseconds to 1 millisecond, for example 100 microseconds, and the cycle is selected from 10 to 20 milliseconds, for example 10 milliseconds.

When the first pulse voltage is applied to the second high voltage generating means 15, the differentiating means 15a is activated to generate the differential output voltage Vd shown in FIG. The differential voltage Vd is received, and the high-voltage pulse generator 15b starts operating in synchronization with this, so that the second pulse voltage V2 is generated in a predetermined phase.

The second pulse voltage has a relatively high crest value but a small time width, and therefore a small energy. The peak value is 10 KV or more, for example 50 KV, and the time width is 0.01 to
0.5 microseconds, for example 0.1 microseconds, and a period of 10 to 20 milliseconds, for example 10 milliseconds, are selected.

By the way, since the first pulse voltage P1 continues when the second pulse voltage is generated, both pulse voltages V1 and V2 are superimposed on each other as shown in FIG. It The time axis of FIG. 11 is expanded from that of FIG.

As a result, the high-pressure discharge lamp 16 is first easily dielectrically broken down by the second pulse voltage having a large peak value, and glow discharge is generated. Next, sufficient energy is supplied by the first pulse voltage having a relatively long time width and thus a large energy, and the glow discharge is switched to the arc discharge. These operations may be performed by first applying each pulse voltage, but the operation is performed as described above at least after several times of repeated application. Therefore, the high-pressure discharge lamp can be easily started or restarted, and can be restarted instantly.

Since the second high voltage generating means 15 is constructed as described above, the first and second high voltage generating means 13 and 15 are reliably synchronized with each other even if they are separated from each other. The first pulse voltage and the second pulse voltage can be applied to the high pressure discharge lamp 16 in a predetermined phase of.

FIG. 2 is a circuit diagram showing a first embodiment of the present invention. This embodiment shows an embodiment of the ballast 12 and the first high voltage generating means 13. The discharge stabilizing element 12a of the ballast 12 is composed of a single choke coil. Note that 12
Reference numeral b is a power factor improving capacitor connected in parallel between the input terminals of the ballast 12. The first high voltage generating means 13 comprises a series circuit of an inductor 13a, a switching means 13b and a capacitor 13c, and the inductor 13a is electromagnetically coupled to a single choke coil. The switching means 13b may be replaced with one having two terminals and one provided with a trigger circuit with three terminals.

The operation of this embodiment will be described. Since the ballast 12 has no boosting action, it is suitable for a 200V power supply. When AC power is applied, the switching means 13b
Turns on at a predetermined phase. Thereby, the capacitor 13c
When the charging current of 1 flows through the inductor 13a, a pulse voltage is generated across the inductor 13a, and the voltage is further boosted by the single choke coil to generate the desired first pulse voltage.

FIG. 3 is a circuit diagram showing a second embodiment of the present invention. In this embodiment, the first high voltage generating means 15 has a first
An example of is shown. The differentiating means 15a comprises a series circuit of a capacitor 15a1 connected between the output lines 14 of the ballast 12 and a primary winding 15a2 of the step-up transformer.

When the first pulse voltage is applied between the output lines 14, the differentiating means 15a operates to generate a differential output as described above. On the other hand, when power is applied between the common side of the output line 14 and the power line 17, the capacitor 15b1 is charged via the step-up transformer 15b4. The capacitor 15b1 cannot be discharged unless the air gap 15b3 is turned on.

When the differential output is generated, the air gap 15
b3 turns on. As a result, the electric charge of the capacitor 15b1 is discharged through the primary winding of the pulse transformer 15b2, so that a second pulse voltage is generated in the secondary winding of the pulse transformer 15b2 and sent to the output line 14.

FIG. 4 is a circuit diagram showing a third embodiment of the present invention. This embodiment shows another embodiment of the ballast 12 and the first high voltage generating means 13. The discharge stabilizing element 12a of the ballast 12 is composed of a leakage transformer. The secondary winding is an insulating type, but may be a non-insulating type if necessary. Since the power factor correction capacitor 12b is connected to the extension winding of the primary winding of the leakage transformer, the capacity of the capacitor can be reduced. The circuit configuration of the first high voltage generating means 13 is the same as that of FIG. 2, but in order to strengthen the coupling with the ballast, the first high voltage generating means 13 is wound so as to be overlapped with or adjacent to the secondary winding.

If necessary, the noise prevention capacitor 12c may be connected.

The operation of this embodiment will be described. When the power is turned on, the lighting tube 13 is activated, and its contact is eventually turned on. After a while, the lighting tube 13 is turned off again. At that moment, the first pulse voltage is generated by the electromagnetic energy accumulated in the discharge stabilizing element 12a of the ballast.

FIG. 6 is a circuit diagram showing a fifth embodiment of the present invention. This embodiment shows another embodiment of the second high voltage generating means 15. The difference from the first embodiment is that a plurality of air gaps 15b3 are changed to three-pole air gaps 15b5. The output terminal of the differentiating means 15a1 is connected to the control pole of the air gap 15b5. Since other configurations are the same as those in FIG. 3, the same parts are denoted by the same reference numerals and the description thereof will be omitted.

The differentiating means is an LR differential type, and is configured by directly connecting the resistor 15a4 and the step-up transformer 15a2. Its action is shown in Figure 3.
Since there is essentially no difference from the above, the description is omitted. The resistor may be replaced with a capacitor.

FIG. 9 is a circuit diagram showing an eighth embodiment of the present invention. This embodiment shows another embodiment of the second high voltage generating means. A semiconductor switching means 15b5 is used instead of the air gap, and a high voltage DC power supply 15b6 is connected between both ends of the capacitor 15b1. In addition, as a charging method of the capacitor 15b1 of the second high voltage generating means,
Modifications such as a multi-stage voltage doubler rectifier circuit, an inverter + step-up transformer, and a relaxation oscillator circuit + step-up transformer are allowed.

It may be externally attached to the ballast, or may be connected separately from the ballast, for example, between the output lines 14. It is effective that the second high-voltage generating means is disposed near the high-pressure discharge lamp, for example, in the main body of the luminaire, but the present invention is not limited to this, and is externally attached to the luminaire main body or the luminaire main body.
