Description

DETAILED DESCRIPTION OF THE INVENTION The present invention attempts to switch the output of a timer in multiple stages and simultaneously dim the load by operating a blinking switch in a power supply circuit.

The status of the lighting load using a conventional flashing switch is ON or OFF.
Although only FF was used, lighting equipment in areas other than living rooms, such as hallway lights, entrance lights, and outside lights, can be considered to contribute to energy savings by dimming them.

When dimming the light equipment in such places, a timer is activated to extend the full lighting state, so that the user is not exposed to the dim dimming state. It is something.

When either of the three-way switches SW1 or SW2 of the circuit in the OFF state is turned on, the current flows from R to L to (B) to (A) to S in Figure 1, and the light bulb L is fully lit.

The control circuit in this state is shown in FIG.
Due to Q' of C1, there is no timer state.

Next, when pushbutton PS1 or PS2 in Figure 1 is operated, the circuit enters a half-wave operation, and the signal circuit (C) in Figure 2 momentarily becomes a no-voltage state, outputting a digital waveform from IC3, and
The count of C1 is advanced by one and set to Q''. When the push button shown in FIG. 1 is operated one more time, the output of IC1 advances by one more step and becomes Q'''. When the output of IC1 is Q'' or Q''', the timer IC2 is activated to keep the photoconductive cell HS in the fully lit state until the settling time, and then shifts to the dimming state.

Signal generation can also be used with gate circuits only.
