A lighting state storage unit 5 (mono-multivibrator circuit 6, flip-flop circuits 7a, 7b, 7c, 3-state buffer circuits 8a, 8b, 8c, AND circuits 9a-9i, OR circuits 3c, 3d) for storing is provided. And this lighting control unit 3
It has a function to change the switching order of the lighting mode when the signal time of the switching signal becomes at least 1 second or more.
By doing so, when the input unit 1 is pressed for 1 second or longer, a signal that the next process is not carried out is stored, and it becomes possible to easily go to the desired lighting mode, which makes it easy to use. It is possible to obtain the luminaire.
Hereinafter, each circuit of FIG. 2 will be described. Switch circuit 1
Is a circuit for shaping the switch input signal 1a to form a switch output signal 1b. The counter circuit 3a has four outputs, and each time a signal is input, the counter outputs A, B, C, and D become logic "1" in sequence, and when a signal is further input, the counter output A becomes logic again. It is a circuit that becomes "1". The mono-multivibrator circuit 6 is a circuit that outputs a signal for a fixed time from the edge of the input signal. The flip-flop circuits 7a, 7b, and 7c have a reset input, a set input, and an output. When the set input is input, the output is a logical "1", and when the reset input is input, the output is a logical "0". The three-state buffer circuits 8a, 8b, and 8c are circuits that have the same logic output as the input when the control input is logic "0", and are in the high impedance state when the control input is logic "1". . Next, the relationship between these circuits and the switch input signal 1a
A description will be given based on FIG. 2 when is input. First, each circuit is in an initial state. That is, the counter circuit 3a
Of the counter output A is a logic "1", the output of the monomultivibrator circuit 6 is a logic "0", and the outputs of the flip-flop circuits 7a, 7b, 7c are a logic "0". (1) If the input time of the switch input signal 1a is short (normal switching signal, time is less than 1 second), the switch circuit 1
Waveform-shapes the switch input signal 1a and outputs the switch output signal 1b as a pulse signal of 1 second or less. The switch output signal 1b is input to the OR circuit 3b. At this time, since the other input is logic "0", the output is directly input to the counter circuit 3a. Counter circuit 3a
In the initial state, the counter output A was logical "1", but the input was input once, so the counter output B was logical "1".
Becomes Since the control input of the 3-state buffer circuit 8a is logic "0", the output E is logic "1".
Further, since the switch time identification circuit including the mono-multivibrator circuit 6 and the AND circuit 9a does not operate, the subsequent circuits also keep the initial values. After that, the switch input signal 1a is 1
In the case of less than a second, outputs F, G, A ... And become logically “1” in sequence. (2) When the input time of the switch input signal 1a is long (when the signal is input to skip the mode and the time is 1 second or longer), the switch circuit 1 waveform-shapes the switch input signal 1a and outputs it for 1 second or longer. The switch output signal 1b is output as a pulse signal. When the pulse output time of the mono multivibrator circuit 6 is set to 1 second or longer, the AND circuit 9a outputs a logical "1" which is the logical product of the pulse output and the switch output signal 1b. At this time, the counter circuit 3a
The following operations are performed depending on the output state of. (B) When the counter output A is logical "1", the output of the AND circuit 9b becomes logical "1" by the logical product, and the flip-flop circuits 7a, 7b, 7c are reset and the output is logical "1". It becomes 0 ". (B) When the counter output B, the counter output C, or the counter output D is logic "1", for example, when the counter output B is logic "1", the AND circuit 9d operates to count the counter output B and the preceding AND circuit 9a. The output becomes a logic "1" by the logical product of and, and the flip-flop circuit 7a is set to a logic "1", so that the output E of the three-state buffer circuit 8a becomes high impedance. At the same time, the output of the AND circuit 9g also becomes a logic "1" due to the logical product, becomes the input of the counter circuit 3a through the OR circuits 3c and 3b, and the counter output C becomes a logic "1". (C) When the counter output B, the counter output C, and the counter output D of the counter circuit 3a are respectively operated for a long time, the outputs of the flip-flop circuits 7a, 7b, and 7c are all output. Since it becomes a logic "1", the output of the AND circuit 9c becomes a logic "1",
After the OR circuit 3d, the flip-flop circuits 7a, 7b,
The reset terminal of 7c is set to logic "1", whereby the outputs of the flip-flop circuits 7a, 7b, 7c are reset to logic "0". FIG. 3 is a block diagram of the lighting fixture of this embodiment. In the figure, the control output A is in the off state, the control output E is in the full lighting state of the main lighting lamp 2a, the control output F is in the dimming state of the main lighting lamp 2a, and the control output G is in the lighting of the auxiliary lighting lamp 2b. And control each. In the figure, for example, the dimming state of the main lighting lamp 2a and the auxiliary lighting lamp 2b
The adjustment procedure for skipping the lighting state of is as follows. The switch input signal 1a of 1 second or less is input to control the control output F to bring the main lighting lamp 2a into the dimming state. Next, by inputting the switch input signal 1a for 1 second or more, the control output F is not output as described above. Next, the switch input signal 1a of 1 second or less is input, and the auxiliary illumination lamp 2b is turned on by the control output G. At this time, switch input signal 1a for 1 second or more
By inputting, the control output G is not output as described above. By performing these operations once, each time the switch input signal 1a of 1 second or less is input, the operation of repeating the full-lighting state and the extinguished state of the main lighting lamp 2a is repeated each time. In FIG. 1, 10 is a power supply, 11 is a switch switching control unit in which a lighting state storage unit 5 is provided in the lighting control unit 3, 10a is a power supply circuit, 10b is a commercial power supply, 10c is a high-voltage power supply, 10d
Is a low voltage power supply. As described above, according to the present embodiment, the user performs the extra switch operation twice each time when using the general appliance, whereas the appliance using the present embodiment presets the lighting mode in advance. In this case, the user does not need any extra operation.

As described above, according to the present invention, since the lighting state storage section for storing a plurality of lighting states is provided in the lighting control section, when the input section is pressed for 1 second or longer, a signal indicating that the next step is not performed is generated. By being stored, it is possible to easily go to a desired lighting mode, and it is possible to obtain a lighting device that is easy to use.
