[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device provided with lighting state control means for switching lighting states in multiple stages.

0002

[Background Art] In conventional lighting devices, when switching between multiple lighting states such as dimming - full light - light bulb on - off, etc., one pull switch is provided to switch sequentially. Alternatively, lighting conditions were switched using a single-circuit power supply wiring and an open/close type power switch, as disclosed in Japanese Patent Publication No. 55-5840.

[0003] In the above-mentioned lighting device, it is necessary to change the switches in sequence in order to obtain a desired lighting state. For this reason, for example, in the case of a lighting device that has a cycle of dimming state - full light state - light bulb on - light off, if you want to change from full light state to dimming state, the light bulb on and off state It was not possible to dim the light without going through the following steps.

[0004] Furthermore, in the case of a lighting device that has a switch for switching the main power supply at the entrance to the room, the main power supply can be turned off.
When you turn it on again, it usually returns to the state it was in just before you turned it off. Also, if you turn off the light with a switch inside the room and want to turn it on from outside the next day, for example, you cannot turn it on with the switch at the doorway, so you have to go through the dark room and turn it on with the switch inside. I had to.

[0005]

[Problems to be Solved by the Invention] As mentioned above, in conventional lighting devices, it is not possible to switch the lighting state such as full light state to dimming state with a single switch operation, and it is difficult to switch the lighting state such as turning off the light. I had to go through a state. Furthermore, when turning on the light from the off state, it was only possible to obtain the illumination state immediately before the light went off. As described above, there has been a problem in that it is not possible to easily shift from a certain lighting state to a desired lighting state.

The present invention has been made in view of these circumstances, and it is an object of the present invention to provide a lighting device that can easily obtain a desired lighting state from any lighting state.

Here, when the output 12a of the inverter control circuit is at a high level and a long on period of the changeover switch 3 is detected, and the output 12a of the inverter control circuit is
In two cases, when a short ON period of the changeover switch 3 is detected when the output 14a of the miniature ball control circuit and the output 7a of the short pulse detection comparator are both at low level, the Q of the flip-flop 25 is The output is inverted, that is, the output 12a of the inverter control circuit is inverted.

The flip-flop 13 is connected to the inverter 16
When the output 7a of the short pulse detection comparator is input to the CK terminal, the Q output 13a is inverted, similar to the flip-flop 25. There is. Note that the output 12 of the inverter control circuit
By supplying a to the R terminal, the flip-flop 13 can be reset and the dimming/full-lighting state of the inverter 16 can be set to the initial state.

The miniature ball control circuit 14 is configured as shown in FIG. 3, for example. The output 6a of the long pulse detection comparator 6 is supplied to one input terminal of an AND circuit 31. Further, the output 7a of the short pulse detection comparator 7 is supplied to one input terminal of the NOR circuit 32 and the CK terminal of the flip-flop 33. The output 12a of the inverter control circuit is supplied to one input terminal of an AND circuit 31 and one input terminal of a NOR circuit 32.

The inverted output of Q and the D terminal are connected, and when a pulse signal is input to the CK terminal, the Q output is inverted. Here, when the output 12a of the inverter control circuit is at a high level and a long on period of the changeover switch 3 is detected, and when the output 14a of the miniature ball control circuit is at a high level, the output 12a of the inverter control circuit, In two cases, when the output 7a of the short pulse detection comparator is both at low level and a short on period of the changeover switch 3 is detected, the Q output of the flip-flop 36 is inverted, that is, the output of the miniature ball control circuit is The output 14a is inverted.

Next, the operation of the lighting device in the first embodiment will be described. In this embodiment, the on-period of the changeover switch 3 is detected by the on-period detection means 10, and based on this detection output, the illumination state control means 11 controls the lamp 1.
and controls the illumination state of the miniature bulb 2.

As shown in FIG. 4, the output 6a of the long pulse detection comparator and the output 7a of the short pulse detection comparator depend on the switch operation 3a of the changeover switch 3, that is, depending on whether the on period is long or short. are output respectively. Here, the voltage across the capacitor 4 in FIG. 1 becomes high when the on period of the changeover switch 3 is long, and is discharged in a low state when it is short. The reference voltage sources 8 and 9 connected to the comparators 6 and 7 have a higher reference voltage VL for the reference voltage source 8 for long pulse detection, and a lower reference voltage VL for the reference voltage source 9 for short pulse detection. A reference voltage VS is set respectively. Therefore, when the on period is long, the long pulse detection output 6a and the short pulse detection output 7a are at a high level, and when it is short, only the short pulse detection output 7a is at a high level.

When the output 12a of the inverter control circuit is at a high level and the on period is short, that is, when only the short pulse detection output 7a is at a high level, the output 12a of the inverter control circuit is determined by the AND circuit in FIG. Since the output of the NOR circuit 21 is at a low level and the output of the NOR circuit 22 remains at a low level, the output 12a is not inverted. Therefore, inverter 16 remains on. In addition, a flip-flop 13 which is a dimming/full-light switching means
The output 13a is inverted every time the short pulse detection output 7a rises, and the dimming/full-lighting state is switched. Regarding the output 14a of the miniature ball control circuit, since the output of the AND circuit 31 in FIG. 3 is at a low level and the output of the NOR circuit 22 remains at a low level, the output 14a
is not reversed.

Next, when the output 12a of the inverter control circuit is at a high level and the on period is long, that is, when both the long pulse detection output 6a and the short pulse detection output 7a are at high level, the AND circuit 21 The outputs of 31 and 31 become high level, and the output 12a of the inverter control circuit
and the output 14a of the miniature ball control circuit is inverted, and the inverter 1
6 turns off and miniature bulb 2 lights up.

[0024] Then, the output 12a of the inverter control circuit
is at a low level, regardless of the on period, when the output 14a of the miniature ball control circuit is at a high level, the output of the NOR circuit 32 is at a high level, and the output 14a of the miniature ball control circuit is inverted and the output 14a of the miniature ball control circuit is at a high level. Ball 2 goes out. Further, when the output 14a of the miniature ball control circuit is at a low level, the output of the NOR circuit 22 is at a high level, the output 12a of the inverter control circuit is inverted, and the inverter 16 is turned on. Note that by resetting the flip-flop 13 here, it is possible to set the dimming/full-lighting state when the inverter 16 is turned on and the lamp 1 is lit.

By the operation of the illumination condition control means 11 as described above, the illumination conditions of the lamp 1 and the miniature bulb 2 are changed as shown in FIG. When the changeover switch 3 is turned on from a state where all the lights are off, the lamp 1 lights up in a dimmed state. Next, when the selector switch 3 is turned on for a short on period, the dimming/full-lighting state is switched. Also, if the selector switch 3 is turned on for a long on period, the lamp 1
goes out and miniature bulb 2 lights up. Then, when the changeover switch 3 is turned on, the miniature bulb 2 is turned off and everything returns to the unlit state. Next, when the changeover switch 3 is turned on, the lamp 1 is turned on in the dimming state immediately before it was turned off, or the desired dimming/full-lighting state is set by resetting the flip-flop 13. and lights up.

Further, in the case of an illumination device in which the lamp 1 has three illumination states, the illumination states are switched as shown in FIG. In this case as well, the dimming A/dimming B/full light state and the lighting/lighting out state can be switched by the ON period of the changeover switch 3 as described above.

As described above, according to the first embodiment, two types of signals having different on periods of the changeover switch are used to
By detecting this on period, it is possible to switch between dimming/full light state and lighting/lighting out state. This makes it possible to easily obtain a desired illumination state from any illumination state.

FIG. 8 is a timing chart showing lighting conditions.

As shown in FIG. 7, in the second embodiment, a reset switch 41 and a reset circuit 42 are provided, and these constitute illumination state reset means. The rest of the structure is the same as that of the first embodiment. The reset circuit 42 is connected to the inverter control circuit 12 and the miniature ball control circuit 14, and these inverter control circuits 1
2 and the miniature ball control circuit 14 are reset.

In the second embodiment, similarly to the first embodiment, by detecting the ON period of the changeover switch 3, the dimming/full-light state and on/off state of the lamp 1 and the light bulb can be determined. The lighting/lighting out state of 2 can be switched. Here, by resetting the inverter control circuit 12 and the miniature bulb control circuit 14 by the reset circuit 42, the lamp 1 and the miniature bulb 2 are switched to a desired illumination state set in advance.

As shown in FIG. 8(A), for example, when the dimming A state is set by resetting, turning on the reset switch 41 with all the lights off,
Lamp 1 lights up in dimming A state. Further, as shown in (B), if the miniature bulb 2 is set to be lit by resetting, for example, when the reset switch 41 is turned on with all lights off, the miniature bulb 2 will be lit. Note that it is also possible to reset the illumination state control means from any illumination state and switch the lamp 1 and the miniature bulb 2 to a set desired illumination state.

As described above, according to the second embodiment, two types of signals having different on periods of the changeover switch are used to
By detecting this on period, it is possible to switch between dimming/full light state and lighting/lighting out state. Also,
By resetting the illumination state control means, the illumination lamp can be switched to a desired preset illumination state. This makes it possible to easily obtain a desired illumination state from any illumination state.

As for the illumination state control means, the illumination state of the illumination lamp can also be controlled by a microcomputer or the like. Also, regarding the on-period detection means,
It is also possible to measure the on period of the changeover switch, determine the length of the on period based on this time, and supply the determination result to the illumination state control means.
