Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dimming device for switching one or more lighting loads on and off, and switching between dimming operation states.

[0002]

2. Description of the Related Art In a conventional dimming device of this type, the operating states of full lighting, extinguishing, and dimming lighting can be switched by operating a switch provided on the device body. Further, in the conventional device, a sensor connected to the outside, for example, a brightness sensor (or a photoelectric automatic blinker) that outputs an on / off signal according to the surrounding illuminance, or a presence or absence of a human body within a detection range is detected. A function to control the lighting load in response to an on / off signal (generally, a no-voltage contact signal is used) from a human body detection sensor (or automatic thermal switch) that outputs an on / off signal Is not provided.

[0003] Therefore, when the above-described photoelectric automatic blinker or automatic thermal switch is used in combination with the dimmer, the photoelectric automatic blinker or the thermal automatic switch is provided between the power supply and the lighting load. A method is adopted in which the above-described conventional device is connected in parallel or in series with a switch or the like, and the function of the dimmer and the function of a photoelectric automatic blinker or the like are combined.

[0004]

However, according to the above-mentioned conventional configuration, the achievable functions differ depending on the difference in wiring between series and parallel. For example, consider a combination with a photoelectric automatic blinker that detects ambient brightness and outputs a signal according to each operating state of lighting, turning off, or dimming according to the detected brightness. When the light control device and the photoelectric automatic blinker are connected in parallel to the power supply and the lighting load, if the light control device is set to “turn off”, the lighting load is adjusted according to the output of the photoelectric automatic blinker. The lighting load is switched between unlit and fully lit, and the lighting load is switched between unlit and dimmed if the dimming device is set to "dimming". The lighting load is always fully lit regardless of the output of the automatic flasher. On the other hand, when the light control device and the photoelectric automatic blinker are connected in series to the power supply and the lighting load, if the light control device is set to “turn off”, the light control device always operates regardless of the output of the photoelectric automatic blinker. The lighting load is turned off, and if "dimming" is set in the dimmer, the lighting load is switched between off and dimming in accordance with the output of the photoelectric automatic blinker. ”, The lighting load is switched between off and full lighting. That is, in the case of the parallel connection, the lighting load cannot be switched between off and dimming lighting in accordance with the output of the photoelectric automatic blinker. It cannot be switched to all lighting.

Therefore, in the above-described conventional example, it is necessary to change the wiring according to a desired function. In other words, there is a problem that the functions that can be realized are limited by the way of wiring. SUMMARY OF THE INVENTION An object of the present invention is to provide a light control device capable of realizing a desired control function with respect to a lighting load regardless of a wiring method with a switch means. .

First, at time t = t ₁ , all the lighting switches 6 are operated and a one-shot signal is output to the control circuit 4.
(See (a) in the figure), the control circuit unit 4 controls the load drive circuit unit 2 to fully light the illumination load L at a dimming level of 100% (see (l) in the figure). . Incidentally, fade on-off switch SW ₁ in this case (see FIG. (G)) from being set off, the lighting load L is totally turned immediately without being turned fade in. The control circuit unit 4 turns off the green light-emitting diodes for display was lit up time t = t ₁ (see FIG. (M)). Then, at time t = t ₂ , the dimming lighting switch unit 7
Is operated and the one-shot signal is also output to the control circuit unit 4.
(See FIG. 2B), the control circuit unit 4 controls the load drive circuit unit 2 to turn on the illumination load L at a predetermined dimming level LV ₂ (for example, 50%). Figure (l)
reference). Further, at time t = t ₃ , when the light-off switch unit 8 is operated and a one-shot signal is input (see FIG. 3C), the control circuit unit 4 controls the load drive circuit unit 2 to control the lighting load. L is turned off (see (l) in the figure), and the green light emitting diode for display is turned on (see (m) in the figure). That is, the green light-emitting diode is lit when the lighting load L is turned off, and is turned off when the lighting load L is turned on (full lighting and dimming lighting), and an operation display is performed when the lighting load L is turned off. The location of the operation unit 6a and the like of the unit 6 can be visually recognized.

Then, at time t = t ₄ , fade-on
Off switch SW ₁ is turned on, after validating the fade function, if the time t = dimmer lighting switch unit 7 in t ₅ is operated (see FIG. (B)), the control circuit unit 4 load drive circuit controls part 2, performs fade-in lighting gradually increasing until the lighting load dimming level LV ₂ of the dimming level set of L (see FIG. (l)). Further, at time t
= The total turn-on switch unit 6 in t ₆ is operated, the control circuit unit 4 controls the load driver circuit portion 2 gradually increases the dimming level to the LV ₂ to 100% of the dimming level LV ₁ (Fade-in).

Here, when the down key switch section 10 is operated when the lighting load L is turned on (time t = t ₇ ), the control circuit section 4 operates while the down key switch section 10 is being operated, that is, the down key. The signal from the switch unit 10 is H
During the level (see (e) in the figure), the load driving circuit unit 2 is controlled to reduce (fade out) the dimming level at a constant rate (see (l) in the figure). On the other hand, if the up key switch section 9 is operated (time t = t ₈ ), the control circuit section 4 keeps the signal from the up key switch section 9 at the H level while the up key switch section 9 is operated. During this period (see (d) in the figure), the load driving circuit unit 2 is controlled to increase (fade in) the dimming level at a constant rate (see (l) in the figure).

Next, two sets of contact input terminals T ₁ , T ₁ , T
_2, to set the dimming level for the contact signal input from the T _2. First, an active set of the dimming level of the first setting switch SW ₂ as ON (time t = t _9, see FIG. (H)). Then, by operating the operation section 10a of the down key switch section 10, the dimming level is set to LV ₁ (= 100
%) To LV ₂ (= 50%) (time t = t
₁₀ , see FIG. (L)). Actually, the brightness of the illumination load L may be set while visually checking the brightness. Thereafter, by operating the operation portion 11a of the storage switch unit 11 (time t = t _11, see FIG. (F)), one of the switching means S set dimming levels LV _{2 per} (= 50
%) Is stored in the storage circuit unit 12 by the control circuit unit 4. Similarly, the first setting switch SW ₂ is turned off,
Second setting switches SW ₃ to set the operation to the dimming level all the lighting switch 6 with switch on the 100% dimming level LV ₁ (time t = t _12, FIG. (H)
(I) (a) (l)) Then, the storage switch unit 1
By operating one of the operation unit 11a (time t = t _13, the see FIG (f)), the contents control of the other switch means S ₂ set dimming levels LV ₁ against (= 100%) The data is stored in the storage circuit unit 12 by the circuit unit 4.

Further, at time t = t ₁₄ , the first and second setting switches SW ₂ and SW ₃ are both turned on, and the fade on / off switch SW ₁ is turned off.
When you are to full lighting of the lighting load L at 100% dimming level LV ₁ (time t = t _15), when the storage switch unit 11 is operated, the two contacts of the switch means S _1, S ₂ If the signal is input overlap, memory circuit portion 1 a dimming level as invalid fade function setting to the effect that full lighting the illumination load L as LV ₁ by the control circuit unit 4
2 is stored. After the lighting load L is turned off by operating the light-off switch section 8 (time t = t ₁₆ ), the time t = t _{16
At 17} , the first and second setting switches SW ₂ , SW
₃ fade on-off switch SW ₁ turned on both with and off, when the illumination load L is turned off (time t = t _18), operating the storage switch unit 11. Thus, when both of the contact signals from the _two switch means S ₁ and S ₂ are no longer input, the setting content of enabling the fade function to fade out and turn off the lighting load L is stored by the control circuit unit 4 in the storage circuit. Stored in the unit 12.

After the above setting is completed, when a contact signal is input from the switch means S _{2 at} time t = t ₁₉ (see FIG. 9 (k)), the control circuit section 4 is set in the storage circuit section 12. controlling the load driving circuit unit 2 in accordance with the content, the lighting load L causes fade lighting up to 100% of the dimming level LV _1, if there are no input contact signal from the switch means S ₂ (time t = t ₂₀₎ Then, the load driving circuit unit 2 is controlled so that the illumination load L is faded out and turned off (see FIG. 1 (l)). Here, while the contact signal from the switch means S ₂ is input, the control circuit unit 4 turns on the red light emitting diode for displaying the presence of the input of the contact signal from the switch means S ₂ (Fig. (O )reference).

Subsequently, when a contact signal is input from the other switch means S _{1 at} time t = t ₂₁ (see FIG. 10 (j)), the control circuit section 4 is set in the storage circuit section 12. The load driving circuit unit 2 is controlled according to the content, and the illumination load L is faded in to the dimming level LV ₂ (= 50%) (see (l) in the figure). At this time, (see FIG. (N)) the control circuit unit 4 to light the red light-emitting diodes for displaying the presence of the input of the contact signal from the switch means S _1. Further, when the contact signal from the other switch means S ₂ is input while the contact signal from the switch means S ₁ is input (time t = t _22), the control circuit unit 4 is a storage circuit section 12 controlling the load driving circuit 2 according to the contents set in, fade-to light the lighting load L to 100% of the dimming level LV ₁ (FIG. (l) refer)
Together, and turns on the red light emitting diode for displaying the presence of the input of the contact signal from the switch means S ₂ (see FIG. (O)). Then, if there is no more input of the contact signal from the switch means S ₂ (time t = t _23), the control circuit unit 4 controls the load driver circuit section 2 in accordance with the contents set in the memory circuit section 12, the lighting load L is allowed to fade from 100% dimming levels LV ₁ to dimming level LV ₂ 50% with (see FIG (l)), emission of red for displaying the presence of the input of the contact signal from the switch means S ₂ The diode is turned off (see FIG. 2 (o)). Finally, at time t = t ₂₄ , when the contact signal from the other switch means S ₁ is also not input (see FIG. 10 (j)), the control circuit section 4 follows the contents set in the storage circuit section 12. The load driving circuit unit 2 is controlled to fade out and turn off the illumination load L (see FIG. 1 (l)).

According to this embodiment, the switch means S ₁ ,
In conjunction with the presence or absence of the contact signal from a photoelectric flasher unit or heat sensitive automatic switch or timer that is connected to a light control device M as S _2, the lighting load L lighting can be turned off and dimming A variety of lighting scenes can be produced automatically. Further, there is no need to change the wiring as in the conventional example in order to make the desired function effective, and the construction becomes easy. Further, when a thermal sensation automatic switch for detecting a human body is connected as the switch means S ₁ , S ₂ , the illumination load L is suddenly turned on by fading in the illumination load L for nighttime visitors. In this embodiment, there is a conflicting need to prevent a surprise of a visitor and to suddenly turn on the lighting load L for an illegal intruder at midnight to fulfill the role of crime prevention. The fading function can be switched between enabled and disabled according to the situation of use and the user's preference, thereby improving usability.

(Embodiment 2) Conventionally, in a general house or store, lighting of a plurality of lighting loads provided in each room,
By changing the light-off state and the dimming state according to the TPO, a lighting effect suitable for the scene is performed. In order to perform various productions suitable for various scenes in this way,
Conventionally, each lighting load is turned on by a combination of an on / off switch and a dimming switch provided for each of a plurality of lighting loads, or a combination of lighting states of individual lighting loads by the on / off switch is stored. One operation of a predetermined switch is to reproduce a stored combination.

However, in the former case where each lighting load is turned on by a combination of an on / off switch and a dimming switch provided for each of the plurality of lighting loads, the lighting state of the plurality of lighting loads is adjusted in accordance with the TPO. This is inconvenient because it is necessary to change each of them individually, and it is difficult to reproduce exactly the same state, and it takes a lot of trouble. In the latter case where the combination of the on / off switches is stored, the same state can be easily reproduced. However, the combination of turning on and off a plurality of lighting loads is monotonous, and the detailed There is a problem that it is not possible to produce a light effect.
