Description

Description: TECHNICAL FIELD The present invention relates to a dimming device for an interior illumination lamp used in a dining room / living room or the like.

[Background Art] An indoor light control device capable of individually adjusting the light of a plurality of indoor lighting lamps according to the purpose of use has been used conventionally. FIG. 4 shows an example of a conventional product, for example, for individually adjusting the lights A, B, C, D of the living room ceiling, living wall, dining ceiling, dining wall, etc. The variable setting operation units Fa, Fb, Fc, Fd are installed side by side, but in actuality, when considering the lighting effect suitable for each time when visiting, eating, hanging after eating, reading, etc. It is troublesome to set the dimming setting, and therefore, there is almost no setting according to the purpose of use.

[Object of the Invention] The present invention has been made in view of the above problems, and an object of the present invention is to provide an indoor light control device in which the light control can be set in advance according to the purpose of use. There is.

DISCLOSURE OF THE INVENTION However, the indoor light control device of the present invention is provided with a plurality of sets of a plurality of variable setting sections for individually performing the light control of a plurality of illumination lamps arranged in a room, and an arbitrary selection switch for each purpose is used. The feature is that one set can be selected. By setting multiple dimming settings in advance, normally, just by operating the selection switch, the dimming suitable for the purpose of use can be immediately performed. It was done so.

FIG. 1 shows an embodiment of the device of the present invention. The indoor light control device of the present embodiment is provided with a plurality of selection switches (S1 to S4) 4 that are operated when the lighting condition in the room is changed according to the purpose of use, and the indoors corresponding to each of these selection switches 4. And a plurality of (16) variable time constant circuits 5 for individually adjusting the dimming of the plurality of lamps A, B, C, D arranged in. Then, each selection switch 4 and the variable setting dial 3 of the variable time constant circuit 5 are arranged on the front panel 2 provided on the front surface of the apparatus main body 1. Here, the variable setting dials 3 are arranged vertically and horizontally in a matrix so as to correspond to the respective selection switches 4 and the lamps A, B, C and D. Further, next to each selection switch 4, a display (“visitor”, “dranran”, “meal”, “reading”) for displaying the purpose of use of the selection switch 4 is attached. FIG. 2 is a block diagram showing the internal circuit configuration of the apparatus. The time constants of the 16 variable time constant circuits 5 provided corresponding to each variable setting dial 3 are set by the variable setting dial 3. Each variable time constant circuit 5 is connected to a lamp driving circuit 6 for controlling the phase of each lamp A, B, C, D via a relay contact operated by the selection switch 4, for example. It is connected.

In FIG. 1, for example, when the purpose-specific selection switch S1 is turned on in order to select the "visitor" mode, the uppermost four variable time constant circuits A1, B1, C1, D in FIG.
Only one is connected to the lamp drive circuit 6, respectively. At this time, operate the uppermost variable setting dial 3 to
The brightness of each of A, B, C, and D may be set while actually watching the brightness, or if the brightness is set in advance, simply turn on the selection switch S1 to set each brightness. The lamp can be turned on with a desired dimming pattern. FIG. 3 shows examples of dimming patterns for each set according to the purpose of use.

[Advantages of the Invention] As described above, in the present invention, a plurality of selection switches that are operated when the illumination state in the room is changed according to the purpose of use, and the selection switches that are arranged in the room corresponding to the respective selection switches. In addition, it has multiple variable time constant circuits that individually set the dimming settings for multiple illuminating lamps, so that you can use the lamps A, B, C, D in advance when visiting customers, hanging out, eating, reading, etc. The dimming level can be set in advance, and the desired dimming pattern can be immediately selected using the purpose-specific selection switch when necessary, so it can be changed each time, for example, when a customer suddenly arrives or when a meal changes to a lazy time. There is an advantage that you do not have to operate the dial to set the dimming degree of each lamp, and there is no danger of breaking the atmosphere on the spot due to a short break for dimming setting, and basically, a variable time constant. Since control is performed lighting state of each lamp in the road, it has a simple circuit configuration, has the advantage of cheaper costs in small systems. Also, since the variable setting dials are arranged in a matrix in the vertical and horizontal directions corresponding to each selection switch and the lighting, the relationship between the selection switch and the variable setting dial can be easily grasped, and further Since there is a display that indicates the purpose of use of the selection switch, it is possible to clearly understand which purpose each selection switch corresponds to, and to set the lighting condition according to each purpose of use. It has the advantage that it can be done easily.
