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 is conventionally used which is capable of individually adjusting the light of a plurality of indoor lighting lamps according to the purpose of use. 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 according to the present invention includes a triac for individually performing phase control of electric power supplied to a plurality of illuminating lamps set indoors, and a triac for performing dimming lighting, respectively. A variable time constant circuit that sets a plurality of phase control states for each triac, a plurality of selection switches that are operated when the lighting state in the room is changed according to the purpose of use, and a selection switch that operates according to the operation of each selection switch A relay having a plurality of contacts for selectively connecting one of the variable time constant circuits provided in each triac, and a power switch for controlling the supply of power to the circuits formed by the above respective configurations. Provided on the front panel of the main body of the device are the selection switches, the power switch, and the dial for operating the variable resistance of the variable time constant circuit. It is characterized in that it is arranged vertically and horizontally in a matrix form in correspondence with the switches and the illumination lamps, and a display indicating the purpose of use of the selection switch is attached next to each selection switch, which is variable in advance. By setting the dimming pattern in multiple desired states with variable resistors of the time constant circuit, it is possible to quickly perform dimming that suits the purpose of use, usually by simply operating the selection switch. .

FIG. 1 shows an embodiment of the device of the present invention. In the figure, m lamps are provided on the front panel 1 of the apparatus body.
N sets for setting the dimming degree of L ₁ , L ₂ , ..., Lm in n ways ×
m variable resistor operating dials 2 are lined up,
A selection switch 3 is provided for each set. Reference numeral 4 is a power switch. FIG. 2 shows the circuit configuration when there are four dimming patterns, that is, when n = 4, and the triac Q ₁ , respectively for each of the illumination lamps L ₁ , L ₂ , ..., Lm.
Q ₂ , ..., Qm are connected in series. In addition, in parallel with each triac, variable resistors VR ₁ , VR ₂ , VR ₃ , VR ₄ and relay contacts r ₁ ,
A variable time constant circuit composed of a variable resistor VR and a capacitor C, which are configured by connecting four sets of series circuits of r ₂ , r ₃ and r _{4 in} parallel, is connected, and the terminal voltage of the capacitor C is a trigger element. It is applied to the gate of each triac via T. In selecting switch for selecting the _{S 1, S 2, S 3} , S 4 dimming pattern, one of which the four relays _{R 1, R 2, R 3} , R 4 is selected, for example, When the relay R ₁ is selected, the relay contacts r ₁ connected to the respective lamps L ₁ , L ₂ , ..., Lm are closed, and the respective time constants of the variable resistor VR ₁ and the capacitor C are different. It will be decided.

Now, in FIG. 1, for example, the dimming pattern selection switch 3 is turned on to select the "customer" mode. In FIG. 2, the selection switch S ₁ is turned on and the relay R ₁
Operates, and relay contacts corresponding to m lamps
When r ₁ is closed, m variable resistors VR ₁ are selected. At this time, by operating the variable setting dial 2 on the uppermost stage of the front panel 1 in FIG. ₁ , the actual brightness of each lamp L ₁ , L ₂ , ... Alternatively, when the dimming degree is set in advance, each lamp can be turned on in a desired dimming pattern simply by operating the selection switch. FIG. 3 shows examples of dimming patterns for each set according to the purpose of use.

[Effects of the Invention] As described above, in the present invention, the triac for individually phase-controlling the electric power supplied to the plurality of illumination lamps set in the room for dimming and lighting, and the triacs respectively. A variable time constant circuit that sets a plurality of phase control states for each triac, a plurality of selection switches that are operated when the lighting state in the room is changed according to the purpose of use, and a selection switch that operates according to the operation of each selection switch A relay having a plurality of contacts for selectively connecting one of the variable time constant circuits provided in each triac, and a power switch for controlling the supply of power to the circuits formed by the above respective configurations. Since it has a configuration, the dimming degree of each lamp at the time of visiting, hanging out, eating, reading etc. is set in advance, and when necessary, select the selection switch according to the purpose of use. You can instantly select the desired dimming pattern, so it is easy to set the dimming degree of each lamp by operating the setting dial each time, for example, at the time of a natural visitor or at the transition from meals to meals. In addition to saving
There is an advantage that there is no danger of breaking the atmosphere of the place due to a short break for dimming setting, and basically the lighting condition of each lamp is controlled by a variable time constant circuit, so the circuit configuration is simple. The advantage is that the cost can be reduced in a small-scale system. Also, since the dials for variable resistance operation are arranged in a matrix in the vertical and horizontal directions corresponding to each selection switch and the illumination lamp, the relationship between the selection switch and the variable setting dial can be easily grasped, and each selection Since a display is displayed next to the switch to indicate the purpose of use of the selection switch, it is possible to clearly understand which purpose each selection switch is for operating the lighting pattern, and each purpose of use There is an effect that the illumination pattern can be easily set according to the above, and further, since the power switch is provided, there is an advantage that the operation when turning off all the illumination lamps can be easily performed.
