BEST MODE FOR CARRYING OUT THE INVENTION One embodiment of the present invention is shown in FIGS.
This will be described with reference to FIG. In the following description, unless otherwise specified, the up, down, left, and right directions are defined in the direction shown in FIG. 8, and the front surface in FIG. 8 is referred to as the front surface.

FIG. 16 is a block diagram of an automatic switch with a heat ray sensor according to the present embodiment, which detects a heat ray from a human body and outputs a signal amplified by a built-in amplifier. 52 and a brightness sensor 53 such as CdS or a photodiode that detects the brightness of the surroundings, the outputs of the motion sensor 52 and the brightness sensor 53 are input to the microcomputer 51. The microcomputer 51 A / D-converts the outputs of the motion sensor 52 and the brightness sensor 53, and further determines the presence or absence of a person in a preset detection area based on the output value of the motion sensor 52. Human sensor 5
The second detection area is set by optical elements such as a lens, a mirror, and a light shielding plate, which are arranged in the path of the heat ray incident on the motion sensor 52. Inside the microcomputer 51, when it is determined that a person is present in the detection area based on the output of the human sensor 52, a human body detection signal is generated.

The microcomputer 51 has a function of turning on / off an opening / closing element 54 such as a triac via a driving unit 55. The switching element 54 is a commercial power supply AC
Connected between the power supply terminals t1 and t2 for connecting the lighting load L and the load terminals t3 and t4 for connecting the lighting load L (that is, between the power supply terminal t1 and the load terminal t4), and the conduction angle is controlled by the microcomputer 51. The power supply to the lighting load L is adjusted to light the lighting load L with a desired light output.
A DC stabilizing power supply 56 that receives a commercial power supply AC and generates a DC constant voltage is connected to the power supply terminals t1 and t2, and the DC stabilizing power supply 56 supplies operating power to an internal circuit.

The basic operation of the microcomputer 51 is such that the human sensor 52 is operated when the brightness detected by the brightness sensor 53 is darker than a preset threshold of brightness.
When a person is detected (when a human body detection signal is generated) based on a change in the heat dose incident on the lighting load L, the lighting load L is turned on (this time is called the operation holding time). ) Is timed by the timer means constituted by the microcomputer 51.

The timer means limits a predetermined operation holding time each time a human body detection signal is generated, and has a so-called retriggerable function. That is, when the human body detection signal is generated before the time-holding operation of the operation holding time ends, the lighting time of the lighting load L is extended by restarting the operation holding time again from the beginning. The operation holding time can be adjusted by the operation holding time setting unit 59.

The operation mode of the microcomputer 51 can be switched to three modes of the automatic mode, the off mode and the continuous on mode by using the operation mode setting section 57. When the automatic mode is set, the microcomputer 51 is operated. Reference numeral 51 automatically controls turning on / off of the lighting load L in accordance with detection signals from the human sensor 52 and the brightness sensor 53. Further, when the operation mode is set to the off mode or the continuous on mode, the microcomputer 51 forcibly turns off or lights the lighting load L regardless of the detection signal of the sensor.

Further, the brightness setting section 58 is used to switch the brightness threshold value between two levels of light (about 80 lux or less) and dark (about 20 lux or less), or a detection signal of the brightness sensor 53. It is also possible to set the lighting load L to be controlled based on only the human body detection signal of the human sensor 52 regardless of the above.
