In the following description, the input switch 8 is described as a push button switch. However, the present invention does not limit the shape of the input switch 8, and a slide switch or a switch that performs a toggle operation may be used.

The brightness setting switch 8d (brightness setting input switch) is used to set the mode of the supplied power in any of the above-mentioned operation modes (sensor mode and manual mode). Then, the brightness setting switch 8d is usually brightness setting switch 8d ₁ for supplying normal power all lighting is obtained, energy saving power setting for supplying reduced power reduction lamp is obtained switch 8d ₂ And That is, the lighting fixture body 1
By adjusting the power supplied to the lighting device 02, the power consumption can be reduced and the dimming of the lighting fixture body 102 can be controlled.

The control of the amount of power reduction is performed by chopping with a semiconductor such as a triac or thyristor provided in the output power control unit 16 or by stepping down by a sliding voltage regulator or a coil. It may be performed by an inverter. Further, the energy-saving power setting switch 8d ₂ by pressing several times, may be able to adjust the power to be phased out. Further, the set amount of power may be displayed on the display unit 16a of the remote controller 1a.

The timer setting switch 8e (input switch for setting the timer) is used to set the mode of the timer circuit 13 which has a meaning in the normal sensor mode. The timer setting switch 8e is a fixed time setting switch 8e ₁ for measuring a certain time by the timer 13 after the power is supplied and turned on to automatically switch off the power and switch off the light. When, and once made the normal supplying setting switch 8e ₂ Metropolitan for up after it is lit by supplying power to the off operation continues to supply power. Incidentally, a predetermined time set by the timer 13 can be changed by the number of times to press the fixed time setting switch 8e _1, in this embodiment example, and can be set up to 30 seconds to 5 minutes. In this embodiment, the timer setting switch 8e has a meaning in the sensor mode. However, the timer setting is also meaningful in the manual mode. For example, the timer setting switch 8e may be turned on for a certain time after pressing the lighting switch 8a. Can be easily considered.

Further, in this embodiment, the time set by the timer 13 can be confirmed by the LED display 13a of the remote controller 1a, but the present invention is not limited to this configuration. For example, LED display 13a
Alternatively, a liquid crystal display may be used, or the determination may be made based on the length and type of the beep sound emitted by the near-infrared / ambient illuminance detection unit 1b when the control signal of the near-infrared ray hν ′ is received. Such a configuration can be applied to the display by the display unit 16a. Further, the timer setting switch 8e may be provided on the lighting fixture 100 side.

Further, the surrounding illuminance monitoring setting switch 8f
The (input switch for ambient illuminance monitoring setting) is for setting an ambient illuminance monitoring mode that is meaningful in the sensor mode. Then, the surrounding illuminance monitoring setting switch 8f
Is ignored illumination control setting switch 8f ₁ for controlling whether to use a lit power supply by the human body detection in accordance ambient illumination, the ambient illumination by ambient illumination detection element 11 monitors the ambient illumination detection element 11 and illumination control stop switch 8f ₂ for, at bedtime, i.e., among the dark before the sun begins, and a sleep control switch 8f ₃ for maintaining the off state in the power non-supply.

It should be noted, by in this embodiment to press the illumination control setting switch 8f _1, a control operation mode for lighting the power supply by the human body detecting when the ambient illumination is bright, by the human body detection when the ambient illuminance is dark The control operation mode for lighting can be switched.
The setting state can be confirmed by the LED display 11a. Note that the LED display 11a may be used to confirm the setting state, as in the case of the LED display 13a described above. The threshold S ₂ as a reference for determining whether dark or ambient illumination is bright, adjustably can be made as indicated by the variable voltage, for example, in FIG. Further, it goes without saying that may be set a threshold value S ₂ in the remote controller 1a.

Further, when you press the sleep control switch 8f _3, together with the signal control circuit 12 stops the supply of power to the output power control unit 16, unless operation by later input switch 8, the human body detection Control is performed so that the output power control unit 16 does not supply power even if the operation is performed. Then, by monitoring the optical sensor 11, it is possible to once again confirm that the illuminance has been darkened after the ambient illuminance has been brightened by the sunshine or the like, and to restart the power supply according to the human body detection.

[0027] By doing so, by the user pressing before bedtime the sleep control switch 8f _3, not only do not accidentally turns on the involuntarily lighting, such as for rolling over while sleeping In the evening of the next day, automatic lighting can be performed again by human detection. It should be noted that the time during which no human body detection is performed can be performed by a long timer that can measure at least the time until the next morning.

Thus, (1) the lighting fixture 10 is provided by combining the infrared detector as the human body detector 5 and the remote controller 1a.
Since 0 can be controlled, wiring work can be eliminated as compared with the case where a system using an infrared switch of a wall or ceiling installation type is introduced.

In particular, the present invention is effective for use in an unfamiliar hotel. (2b) Further, in a living room or the like, the daily act of pressing a lighting switch once a day to turn it on in the evening can be eliminated.

(3) The light-off switch 8b, which stops the lighting of the lighting fixture body 102 when pressed, is provided with a certain period of time (for example, about 10 seconds) of a dead time for human body detection. In this case, it is possible to prevent lighting of the unmanned room after leaving, and to avoid waste of lighting in the unmanned room. That is, even if the light-off switch 8b is pressed from the lighting state and the human body H is in the infrared detection range of the pyrosensor 2 even after the light-off switch 8b is forcibly extinguished, the unmanned room is illuminated. In the remote controller 1a or the lighting fixture 100, a function of detecting the infrared rays from the human body H in the infrared detection range and lighting the lighting fixture 100 for a predetermined time (for example, about 10 seconds) is provided. In other words, the near-infrared remote controller control unit 6 on the remote controller 1a side and the lighting equipment 1 do not generate the near-infrared ray hν ′ ignoring the human-body detection signal from the human body detector 5.
