Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is a load control device using a soft touch switch, in particular, a load control device that uses a soft touch switch and a digital ■○, and presses and operates one soft touch switch. The present invention relates to ON-OFF control of a plurality of loads, and is suitable for, for example, combined drive control of a lighting device in which a plurality of lamps are switched in a predetermined order.

[Conventional technology]

This type of load control device that sequentially switches multiple loads with a single switch can be used, for example, to switch multiple lamps such as main lighting lamps, auxiliary lighting lamps, and night bulbs using a wall switch.
There is a device that performs a series of lighting control such as dimming, turning off the light at night, and turning off the light at all times (see Japanese Patent Publication No. 55-5840).

However, this lighting control device requires multiple relays, has a large number of parts, and is not easy to assemble, and the relay contact retention is OR
, the wall switch operation time is limited, resulting in poor operability.

[Problem to be solved by the invention]

The present invention has been proposed in view of the above, and an object of the present invention is to provide a load control device that uses individual soft-touch switches to drive and control multiple loads with good operability and has good assembly workability.

[Failure to solve the problem]

For this reason, the present invention utilizes a soft touch switch that emits a pulse signal every time a pressing operation is performed, a plurality of output terminals that sequentially switch and output a high level output every time a pulse signal is input to an input terminal, and a reset signal. A digital IC of a recade counter has a reset terminal that returns the level output to the first output terminal, and the output terminal is switched between high level and low level every time a pulse signal is input to the input terminal, and the output terminal is reset by inputting a reset signal. A control circuit is constructed with a flip-flop digital IC each having a plurality of reset terminals for setting the signal to a low level, and is configured to control a plurality of load circuits in combination.

More specifically, each of the plurality of sets of output terminals of the digital IC of the flip-flop is connected to a switch element corresponding to each of the plurality of controlled load circuits.

Therefore, a digital IC having at least as many output terminals as the number of controlled load circuits is used.

Further, among the plurality of output terminals of the digital IC of the recade counter, at least the output terminal in the previous stage position is connected to the input terminal of the flip-flop digital ■C related to the controlled ON-driving load circuit, and The output terminal in the next stage position following this is the OF of the ON drive load.
It is connected to the reset terminal of the clip-flop digital IC in connection with the load circuit to be driven by F.

[For production]

According to the above configuration, the first suppression operation of the soft touch switch can drive the predetermined load circuits in combination, and the subsequent suppression operation of the soft touch switch can turn off the load being driven. A plurality of load circuits can be freely combined and driven by pressing the soft touch switches.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a circuit diagram showing an example of a load control device 1 using a soft touch switch according to the present invention.

In the figure, 2 and 3 are two power loads that are driven and controlled, and are the first and second lamps in the lighting equipment. These first and second lamps 2 and 3 are connected to an AC power source 6 via first and second phototriacs 4 and 5, which are semiconductor switches, respectively. Each of the first and second phototriacs 4 and 5 has a first and a second switching transistor 7.

Further, 10 is a DC power source that supplies DC to the first and second switching transistors 7.8 and the control circuit 9.

On the left side of the control circuit 9, one soft touch switch 11 is connected to a DC power source 10 via a parallel circuit including a capacitor C and a resistor that generates a pulse potential. This soft touch switch lll1 is a tact switch whose contact point closes when the touch operation is lightly pressed and returns to normal when the pressure is released, and a pulse signal is generated in the leader line every time the switch J1 is touched. In addition, the next stage 12 is a digital IC of a Ricade counter, which has an input terminal (■), a plurality of output terminals Ql, Q2 r Qa, and a reset terminal R, and every time a pulse signal is input to the input terminal (■), The output terminal is switched from Ql to Q2 + Qa to output a high level. Also, when a high level is input to the reset terminal R, one of the output terminals Q is at a high level.

and second output terminals b and b', and two sets of input terminals each consisting of first and second reset terminals c and c', which respectively set these output terminals and b' to a low level by inputting a reset signal. , a Noritsu flop digital IC having an output terminal and a reset terminal group, each first
and second output terminals S, b' are connected to first and second switching transistors 7 and 8, respectively, which switch-control the first and second lamps 2, 3, respectively. The first output terminal Q1 of the Ricade counter is connected to the first and second input terminals a of the digital C13 through a series connection of a color mixing prevention diode D and a parallel connection of a pulse generation capacitor C and a resistor. , a', and when the soft touch switch 11 is pressed for the first time, the first
and a second lamp is activated to obtain a so-called full light-on condition.

Further, the second output terminal Q2 is connected to the first glue set terminal C of the digital IC. Therefore, by the second pressing operation of the soft touch switch 11, the first lamp 2 which is in the lighting state is turned off, and the second lamp 3 is continuously turned on, thereby obtaining a so-called dimmed lighting state.

Furthermore, the third output terminal Q3 is connected to the second reset terminal C' of the digital IC and to the reset terminal R of the recharge counter. Therefore, by pressing the soft touch switch 11 for the third time, the second lamp 3, which is lit in a dimming nail shape, is turned off, and a so-called light-off state is obtained. At the same time, the reset terminal R of the recade counter 12 is activated and the output is returned to the first output terminal Q1. Therefore, the fourth and subsequent pressing operations of the soft touch switch 11 perform the same lighting driving operation as those after the first pressing operation.

〔Effect of the invention〕

As described above, the present invention combines a soft-touch switch and a digital IC, and is configured to sequentially drive and control multiple loads by suppressing one soft-touch switch. In addition to improving operability, parts can be consolidated and assembly is improved.

In the above embodiment, the load is configured with only two circuits, but it is also easy to configure the load with three or more circuits.

Also, the drive control was all lights → spectroscopy → off, but spectroscopy →
It is also easy to perform appropriate load driving such as full light→spectral light→turn off.
