ようにしたものである。[Detailed description of the invention] The present invention is a discharge lamp stage dimmer that switches between full lighting and dimmed lighting of the discharge lamp when the power supply current interruption time is within the reference time, and the reference time is short. The above switching can be carried out reliably with a simple operation.

生じる。 The lighting device is equipped with a switch that switches between main lighting and auxiliary lighting, and controls the switch to switch from lighting the main lighting to lighting the auxiliary lighting when the power supply current cutoff time is within the reference time. An invention is already known (Japanese Patent Publication No. 17353/1983) that allows switching between main lighting and auxiliary lighting with a simple operation. Therefore, it is conceivable to apply the present invention to a discharge lamp stage dimmer device so that the discharge lamp can be switched between full lighting and dimmed lighting with a simple operation. However, in this case, if the reference time is set for a long time, it will not only cause technical and cost disadvantages due to the need to increase the capacitance of the capacitor for setting the reference time.
The discharge lamp will go out and the discharge lamp will not be able to maintain full or dim lighting. Therefore, it is necessary to set the above-mentioned reference time to a short time (for example, within 1 second), which makes it difficult to cut off the power supply current within the reference time, making it difficult to turn on the entire discharge lamp and turn it on in a dimmed manner. The problem arises that the switching is not successful.

点にある。 This invention solves the above problems, and its feature is that it is equipped with a switch that switches between full lighting and dimming of the discharge lamp, and when the power supply current cutoff time is within the reference time, full lighting is provided. In a discharge lamp stage dimmer in which a changeover switch is controlled to switch between lighting and dimmer lighting, a power cutoff switch and a manual switch are provided, and a first switch is activated when the manual switch is turned on to turn off the power cutoff switch. The present invention includes a relay and a second relay that is activated by the first relay to stop the first relay within the reference time.

R3は抵抗である。 Hereinafter, the present invention will be explained according to the illustrated embodiment. In FIG. 1, E is an AC power source, SW 1 is a power switch, L is a discharge lamp, and CH 1 and CH 2 are chain yoke. X 1 and X 2 are relays, and relay X 1 is a contact
It has X 1a and B contact X 1b , and relay X 2 has A contact X 2a.
and a b contact X 2b , and the contacts X 1a , X 1b , X 2a , X 2b
This constitutes a changeover switch SW 2 that switches between full lighting and dimmed lighting of the discharge lamp L. C 1 and C 2 are capacitors, R 1 and R 2 are resistors, and D 1 and D 2 are diodes. When the power supply current cut-off time by turning on and off the power switch SW 1 is within the reference time (about 1 second),
The switch SW 2 is configured to control the discharge lamp L from dimmed lighting to full lighting.
R 3 is the resistance.

る。 SW 3 is a manual switch, and Y 1 is the first relay, which has two a contacts Y 1a and a b contact Y 1b , and the b contact Y 1b is connected in series to the power switch SW 1 and acts as a power cutoff switch. It forms SW 4 . Y 2 is a second relay, which has an a contact Y 2a and a b contact Y 2b , and is activated by turning on the a contact Y 1a and turning off the b contact Y 2b to switch the first relay Y 1 within the reference time. to stop.

る。 Next, the operation will be explained. When power switch SW 1 is turned on, relay X 1 is activated through B contact X 2b , so A contact X 1a turns on and B contact X 1b
is turned off, and then relay X 2 is activated as the capacitor C 1 is charged, turning on the a contact X 2a and turning off the b contact X 2b . A current flows through the discharge lamp L, and the discharge lamp L is dimmed and lit. The capacitor C2 is charged at the same time as the discharge lamp L is dimmed and turned on, and its capacity is large, so if you turn off the power switch SW1 while the discharge lamp L is dimmed and turned on, the capacitor C2 will be charged for a while (about 1 second) afterward.
The operating state of relay X 2 is maintained by the discharge current of C 2 . On the other hand, relay X 1 returns to the stopped state at the same time as power switch SW 1 is turned off. Therefore, if the cutoff time of the power supply current is shorter than the reference time, the contacts X 1b and X 2a of the changeover switch SW 2 will turn on contacts X 1a and X 2b.
is turned off, current flows through the discharge lamp L from the power source E through only one of the channels CH2 , and the discharge lamp L is fully lit. However, if the cut-off time is longer than the reference time, both relays X 1 and X 2 stop and the discharge lamp L goes out, and then the next power switch SW 1 is turned on and the discharge lamp L is adjusted again in the same way as above. The light turns on. Furthermore, if the power switch SW 1 is turned off while the discharge lamp L is fully lit, the residual charge in the capacitor C 2 will be discharged through the resistor R 1. Moreover, since the capacitor C 1 is only for rectification and has a small capacity, the relay X 2 will be turned off. It immediately stops and returns to its original state.

単かつ確実に切替えることができる。 Then, when manual switch SW 3 is turned on when power switch SW 1 is turned on, manual switch SW 3 is turned on.
Relay Y1 is activated through contact B and Y2b , turning on contact Y1a and turning off contact B , that is, power cutoff switch SW4 . Next, when the a contact Y 1a is turned on, the relay Y 2 is activated, and the a contact Y 2a is turned on, and the b contact Y 2b is turned off, and then the b contact Y 2b is turned on.
relay Y1 stops within the reference time due to turning off,
As a result, the a contact Y1a is turned off, and the power cutoff switch SW4 is turned on reliably within the reference time from the above-mentioned on point. After that, the relay Y2 is stopped by turning off the a contact Y1a , and the state returns to the original state. Therefore,
Since the operating time of relays Y 1 and Y 2 is from several mS to several tens of mS, by simply turning on manual switch SW 3 during dimming lighting, it is possible to ensure that the power supply current is cut off within the standard time. Thus, the discharge lamp L can be easily and reliably switched from dimmed lighting to full lighting without fear of going out.

とができる。 Figure 2 shows another embodiment, in which the second relay Y2 is operated for a certain period of time (within 0.05 seconds) to
This uses a timer relay that turns off contact Y 2b . To explain its operation, when manual switch SW 3 is turned on, relay Y 1 is activated through switch SW 3 and B contact Y 2b , and A contact Y 1a is turned on . When it turns on, power cutoff switch SW 4 turns off and the relay
Y 2 is activated. Then, after a certain period of time (within 0.05 seconds) has elapsed, the B contact Y2b is turned off, the relay Y1 is stopped, the A contact Y1a is turned off, and the power cutoff switch SW4 is turned on. Thereafter, relay Y2 is stopped by turning off contact Y1a and returns to its original state. Therefore, in this case as well, the power supply current can be reliably interrupted within the reference time by a simple operation as in the above embodiment.

Instead of this, the discharge lamp L is switched from full lighting to dimming when the power supply current cutoff time is within the reference time when the lamp is fully lit. In short, it can be applied as long as it switches between full lighting and dimmed lighting of the discharge lamp L when the cutoff time of the power supply current is within the reference time.

る。 According to the present invention, a power cutoff switch and a manual switch are provided, a first relay is activated to turn off the power cutoff switch when the manual switch is turned on, and a first relay is activated by the first relay to turn off the power cutoff switch within the reference time. Since the power switch is equipped with a second relay that stops the power supply, the power switch can be turned off and on in an extremely short time by turning on the manual switch. Therefore, the reference time can be set quite short. Even if the power supply current is cut off within the standard time, it can be done with a simple operation.
To easily and reliably switch between full lighting and dimmed lighting of a discharge lamp without fear of it going out.
