Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is an overall block diagram, and FIG. 3 is a perspective view of the main body 1. The main body 1 is detachably mounted on a standardized mounting plate 2 embedded in a wall or the like, and is connected to a commercial power supply and a lighting fixture 3 as a load via a power supply line on the rear side. .

A human body detection sensor 4 composed of a pyroelectric element is disposed on the front surface of the main body 1, and an optical sensor 5 composed of CdS for detecting ambient brightness is disposed below the human body detection sensor 4. A changeover switch 6 for switching between various modes is arranged below the optical sensor 5. A time display plate 7 composed of an LCD is disposed on the upper front of the main body 1, and a time setting unit 8 for setting the current time and operation time and displaying the current time in accordance with a normal position is provided below the time display plate 7. ing. Further, feed buttons 9 and 10 for setting "hour" and "minute"
Is provided.

In FIG. 2, a relay contact 13 of a relay drive circuit 12 driven and controlled by a CPU 11 is inserted and connected in a power supply line between a commercial power supply and a lighting fixture. Is controlled to blink. The CPU 11 receives signals from the optical sensor 5, the human body detection sensor 4, the delay time extinguishing time contact unit 17, the timer control unit 15, and the changeover switch 6 for switching the lighting mode. Power for each circuit is supplied from a power supply circuit 16.

The changeover switch 6 has a "OFF" switching position for setting the OFF mode for continuously turning off the lighting equipment, and a "ON" switching position for setting the ON mode for continuously lighting the lighting equipment. A switching position of “automatic” for setting an automatic mode for turning on a lighting fixture when the surroundings are dark by a signal from the optical sensor 5 and a human body is detected by a signal from the human body detection sensor 4, "Continuous timer" that turns on the lighting equipment continuously by a signal from the sensor 5 and switches to the automatic mode when a preset time comes and turns on the lighting equipment only when a human body detection sensor detects a person. Switching position.

When a person sets the changeover switch 6 to the "continuous timer" position instead of operating the switching between the off mode, the automatic mode, and the continuous mode, an electronic timer, that is, a timer control unit shown in FIG. The CPU 11 is controlled at 15 to automatically switch from the continuous mode to the automatic mode. FIG. 1A shows the operation mode when the changeover switch 6 is set to the “continuous timer” position, and the switching time from the continuous mode (continuous timer mode) to the automatic mode is set in advance. In this example, PM10: 30. In the evening (for example, PM5: 30), when the light sensor 5 is activated and the changeover switch 6 is in the “continuous timer” mode, the lighting equipment is turned on and the preset PM10: 30 is reached. If you switch to automatic mode,
Until the morning when it becomes bright thereafter, the lighting equipment is automatically turned on by the output of the human body detection sensor 4 only when a person is detected, and otherwise, the lighting equipment is turned off.

When the surroundings become brighter in the morning, the mode is switched from the automatic mode to the cutoff mode by the output of the light sensor 5, and the cutoff mode is set to turn off the lighting equipment in the daytime. The automatic switching of the mode is performed by the CPU
Going at 1. In addition, the brightness of the surroundings for lighting the lighting device which is in the continuous timer mode in the evening is, for example, 100 L
