In order to create an atmosphere suitable for the purpose of use of the room, it has several lighting patterns, and when the lighting pattern is changed, the lighting of the lamp is gradually brightened (fade in) or gradually darkened (fade out). There is an illumination device that performs dimming lighting.

In such a lighting device, a dimming level is designated by a remote controller, and the main power of the device is turned on / off by a wall switch.

[0004]

However, if a power failure occurs during the transition to the instructed dimming level, or the wall switch is inadvertently operated to turn off the main power of the apparatus, the power recovery from the power failure or the wall failure occurs. Even if the power is turned on by the operation of the switch, the control means of the apparatus is reset, so that the lamp does not turn on and the lighting operation has to be performed again.

It is difficult to make adjustments while checking the dimming level.

By the way, at the time of dimming lighting of the lamp,
An appropriate dimming level change rate can be set for each of the dimming lighting or all-light lighting from the unlit state, the dimming from the intermediate dimming lighting state, and the dimming from the all-light lighting state. But,
When the rate of change changes in this way, when dimming a plurality of lamps individually, it is difficult to visually grasp the change in brightness by each lamp, and the effect of dimming is low.

FIG. 1 shows a circuit diagram of an illuminating device, which includes an incandescent lamp 1, a high-intensity lamp 2 and a discharge lamp 3 as light sources. These light sources may be located in a single instrument or at different locations in the room.

The incandescent lamp 1 and the high-intensity lamp 2 are connected to a commercial AC power supply 4 via triacs 5 and 6 as dimming means, respectively. A series circuit composed of capacitors 7, 8 and resistors 9, 10 is connected in parallel with the triacs 5, 6, respectively.

The discharge lamp 3 is connected to dimming means 11 connected to the commercial AC power supply 4. This light control means 11
It is composed of a triac 12 and an inverter lighting device 13. Reference numeral 14 denotes a starting capacitor.

Each of the triacs 5, 6, and 12 is connected to control means 15. The control means 15 variably controls the amount of power supply to the incandescent lamp 1 and the high-intensity lamp 3 by the triacs 5 and 6, and variably controls the power supply to the inverter lighting device 13 by the triac 12. Therefore, dimming and lighting control of each of the lamps 1, 2, and 3 is performed, and fade-in and fade-out control are performed when the dimming level is changed. The dimming lighting means, for example, 5
Lighting at a dimming level such as 0% brightness and lighting at a full light level are also included.

The control means 15 is connected to a receiving section 17 for receiving a remote control signal transmitted from the remote control 16 as a dimming instruction means. Then, the control means 15 performs corresponding control based on a command from the remote controller 16.

The control means 15 is connected to a storage means 18 such as an EEPROM or a memory having a backup power supply, the storage of which is not erased even when the power is turned off.

Next, the operation of this embodiment will be described.

When the dimming level is instructed by operating the remote controller 16, the remote controller signal is received by the receiver 17 and input to the control means 15 (step 1).

The control means 15 first stores the designated dimming level in the storage means 18 (step 2). continue,
The brightness of each of the lamps 1, 2, 3 is gradually increased or the brightness is gradually reduced, and the lamps are dimmed and turned on to the designated dimming level (steps 3, 4). FIG. 2A shows a dimming start point A and a dimming end point B at a specified dimming level.

At an intermediate point C between the light control start point A and the light control completion point B, for example, a temporary power failure occurs, or the main power switch of the apparatus is inadvertently turned off. Then, the power of the apparatus is turned off, the lamps 1, 2, and 3 are turned off, and the current data in the control means 15 disappears.

After that, when the power of the apparatus is turned on again by the recovery from the power failure and the turning on of the main power switch, the control means 15
The dimming level data stored in the storage means 18 is read out (steps 5 and 6), and the process proceeds to step 3, where the lamps 1, 2 and 3 are turned on at the read dimming level. Of FIG.
(b) shows the dimming start point A1 and the dimming end point B1 of the read dimming level.

Therefore, the storage means for storing data even if the dimming level specified by the remote controller 16 is turned off.
Even if the power of the apparatus is turned off during the transition to the specified dimming level, the dimming level is read from the storage unit 18 when the power is turned on again, and the lamps 1 and 2 are stored.
Lights 2 and 3 can be reliably turned on at the specified dimming level.

Next, an embodiment according to the second aspect of the present invention will be described with reference to FIGS.

The remote controller 16 as the dimming instruction means has dimming buttons (not shown) for raising and lowering the dimming level, and generates a corresponding dimming signal in a stepwise manner only while the dimming button is pressed. Output. As shown in FIG. 5, the dimming signal first outputs a normal signal including the dimming up / down identification control data, and subsequently does not include the identification control data, but indicates a shortened signal indicating that the operation is continued. Is output intermittently.

The control means 15 receives a stepwise dimming signal from the remote controller 16 and continuously dims the lamps 1, 2, 3 during the signal input based on the dimming signal.

The control means 15 has a function of a light control holding means 15a for holding the change of the dimming level by the control means 15 at a constant level for a certain period of time when the dimming signal is input to the control means 15. Have.

Then, when, for example, a light control button for increasing the light control of the remote control 16 is operated, a light control signal is output from the remote control 16. First, the control means 15 inputs a normal light control signal (steps 11 and 12), and raises the light control levels of the lamps 1, 2 and 3 by a certain level (step 13).

The control means 15 subsequently receives the shortened signal of the dimming signal, counts it with a counter provided in the control means 15, and waits until the count value becomes 7 (steps 14, 14).
15, 16). That is, the dimming level of the lamps 1, 2, and 3 is held at a constant level for a fixed period by the function of the dimming holding unit 15a of the control unit 15. This period is set longer than a normal time described later.

When the count value reaches 7, the counter is reset (step 17), and the process proceeds to step 13, where the dimming levels of the lamps 1, 2, and 3 are increased by a certain level.

Thereafter, the flow advances to step 18 to count the shortened signal. When the count value reaches 2, the counter is reset (steps 19 and 20), and the flow advances to step 13 to control the dimming level of the lamps 1, 2, and 3. Is raised by a certain level.

Thereafter, each time the count value of the shortened signal becomes 2, the dimming level of the lamps 1, 2, 3 is increased by a fixed level.

Therefore, in the case where the light control button is pressed for a short time and the light control level is adjusted while confirming the light control level, the light control level is initially constant even if the time during which the light control button is pressed is slightly different depending on the operator. Since the light control level is maintained, the light control level can be easily adjusted while checking the light control level.

The function of suppressing a change in the dimming level at the initial stage of the operation may be provided on the remote controller 16 in accordance with the third aspect of the present invention. That is, the remote controller 16 is operated when the dimming level of the lamps 1, 2, and 3 is changed. During the continuous operation, the remote controller 16 continuously outputs a dimming signal that changes stepwise. Output with a longer variation range.

The control means 14 inputs a dimming signal that changes stepwise from the remote controller 16, and dims the lamps 1, 2, and 3 during signal input based on the step change of the dimming signal. I do.

In the case where the light control operation is performed for a short time and the light control level is adjusted while confirming the light control level, the light control signal is initially provided even when the light control operation time is slightly different depending on the operator. The dimming level does not change significantly by increasing the stepwise change width of the output.

The control means 15 dims each of the lamps 1, 2, 3 at the dimming level designated by the remote controller 16 at the corresponding constant change rate stored in the change rate storage means 18a.

FIG. 8 shows an example of lamp dimming, which shows a change in apparent brightness. In the figure, the one-dot chain line is the incandescent lamp 1 and the high-intensity lamp 2, the broken line is the discharge lamp 3, and the two-dot chain line is another discharge lamp (not shown).

When the lighting is instructed by the remote controller 16, the control means 15 reads out the rate of change of the dimming level for each of the lamps 1, 2 and 3 from the rate-of-change storage means 18a, and uses the rate of change. Dimming is performed so that the brightness of 1, 2, and 3 is constantly increased. It should be noted that the discharge lamp indicated by the two-dot chain line is all-lighted in accordance with all-lighting of the lamps 1, 2, and 3.

When the light-off is instructed, the rate of change is read out, and the dimming is performed so that the brightness of the lamps 1, 2, 3 is reduced at a constant rate. At the start of dimming of the lamps 1, 2, and 3, the discharge lamp indicated by the two-dot chain line is turned off.

FIG. 9 shows another example of dimming of the lamps. The dimming state for producing the atmosphere of the room is shown for each of scenes 1-4.
Perform each time. In each of scenes 1 to 4, a combination of lighting and extinguishing of a plurality of lamps and a dimming state are set. Then, when shifting from one scene to another scene, as described above, dimming is performed at a constant change rate of a dimming level predetermined for each lamp.

Therefore, since the brightness of each lamp changes at a predetermined constant rate of change, it is easy to visually grasp the change in brightness by each lamp, and the effect of dimming can be enhanced.

The constant change rate of the dimming level stored in advance in the change rate storage means 18a may be set differently for each lamp, and may be arbitrarily selected by a switch or the like. Is also good.

The rate of change of the dimming level between scenes 1 to 4 may be set to be different from that at the time of dimming from off to on or from on to off.
