  The problem to be solved is that when installing a lighting device using a human sensor to various wiring fixtures fixed on the ceiling surface, the work is done at a high place near the ceiling, and the main body becomes a blind spot and the fitting work is not possible. Difficult, especially in the case of a square hook ceiling, there is a risk of damaging the square hook ceiling by rotating the main body in an incompletely fitted state. In addition, the human sensor is locked at the fitting position and cannot be locked at an arbitrary position.

  When the lighting device using the human sensor is attached to the round hook ceiling, the round full hook ceiling, and the full hook rosette fixed to the ceiling surface, the hook ceiling plug blade of the main body is connected to the wiring by the positioning guide. It enables easy positioning and fitting to the blade holder of the instrument. By strongly rotating the main body to the right, the human sensor is locked at an arbitrary position, and the detection area can be adjusted to an arbitrary angle. The square hook ceiling, the hook embedded rosette and the hook exposed rosette can be easily positioned and fitted by using an adapter.

  The lighting device using the human sensor according to the present invention can be fitted with various wiring fixtures fixed to the ceiling surface, locked to an arbitrary position of the human sensor, and an arbitrary sensing area of the human sensor. Because it can be adjusted to an angle, it contributes to extremely effective use.

  The round hook ceiling, round full hook ceiling and full hook rosette blade holders, and the hook ceiling plug of the lighting device body are easily positioned and fitted with a positioning guide for handling blind spots. To do. The human sensor is locked at an arbitrary position by strongly rotating the main body to the right by the contact mechanism that rotates and rubs. Further, the detection area of the human sensor can be adjusted to an arbitrary angle by a mechanism for adjusting the installation angle of the human sensor. For square hook ceilings, the adapter A attached to the positioning guide of the main body, and for the hook embedded rosette and the hook exposed rosette, the adapter B attached to the rosette, just like the round hook ceiling It is characterized by enabling positioning and fitting.

  FIG. 1 shows an embodiment of a lighting device using a human sensor according to the present invention, which is a round hook ceiling 2, a hook ceiling lighting fixture 5, and a round hook ceiling 2 and a hook ceiling type installed on a ceiling surface. FIG. 2 is an exploded perspective view of the main body 1 that is electrically interposed between the lighting fixture 5 and FIG. 2 is a cross-sectional view of the main body 1 taken along line AA and a.

  When the main body 1 is attached to the round hook ceiling 2, the main body 1 becomes a blind spot, and the round hook ceiling 2 cannot be seen. For this purpose, a circular pedestal 8 to which the hooking sealing plug blade 7 of the main body 1 is attached is provided with a positioning guide 9 that opens in a cylindrical shape that matches the outer diameter of the circular hooking ceiling 2. By positioning the round hook ceiling 2 in the positioning guide 9, the main body 1 and the round hook ceiling 2 can be positioned easily. Then, the main body 1 is rotated while being pushed lightly on the ceiling surface. When the hooking stopper blade 7 and the blade receiving groove 10-1 of the blade holder 10 of the round hook ceiling 2 are brought into contact with each other by the rotation, the main body 1 is moved to the hooking sealing plug blade 7. When the blade 7 is further rotated to the right from there, the plug blade 7 moves to and fits into the power feeding groove 10-2 of the blade receiver 10. (Fitting torque 2 N · m or less) Removal is performed by rotating the main body 1 counterclockwise. (Removal torque 0.5N ・ m or more)

  The human sensor 6 is installed at a position separated from the main body 1 in order to avoid the influence of heat generation from an incandescent light bulb (not shown). Further, in order to prevent the hook-and-ceiling lighting fixture 5 from becoming a blind spot in the detection area of the human sensor 6, it is necessary to lock the human sensor 6 at an arbitrary position. The contact mechanism 11 is provided between the fixed contact 11-1 on the main body side and the movable contact 11-2 on the hooking ceiling pedestal 8 side. FIG. 2.a shows a perspective view of the movable contact 11-2. The contact spring 11-3 is rotationally rubbed while being pressed against the fixed contact 11-1. The human sensor 6 is locked by strongly rotating the main body 1 from the fitting position to the right. The rotational friction torque is a rotational torque stronger than the fitting torque, for example, 4 N · m or more, and is adjusted and fixed by the central shaft bolt 12 and the screw 12-1. Further, a mechanism composed of the rotating part 13 and the tilt part 14 is provided at the attachment part of the human sensor 6 to adjust the installation angle of the human sensor 6. Thereby, the detection area of the human sensor is adjusted to an optimum angle according to the installation environment. The main body 1 and the hook ceiling type lighting fixture 5 are fitted by the blade holder 16 of the main body 1 and the plug blade 20 of the hook ceiling type lighting fixture 5. Further, a display lamp and an illuminance sensor are arranged near the human sensor 6. (Not shown)

The fixed contact 11-1 is connected to the commercial power input terminal T1 of the circuit board 15. For output to the lighting load, one end 12-3 on the opposite side of the central shaft bolt 12 and the output terminal T2 of the circuit board 15 are connected to a pair of blade supports 16.

  The power supply unit 15-1 of the circuit board 15 outputs a direct current constant voltage obtained by rectifying and stabilizing a commercial power supply in two systems, that is, a power supply that rapidly drops in voltage and a power supply that slowly drops in voltage. The mode setting switching control unit 15-2 includes initial mode settings for the short-time timer mode and the long-time timer mode, mode switching using the potential difference between the two power sources when the wall switch “disconnect / connect” is operated, and the long-time timer mode. Automatic switching when the time limit expires is instructed to the illumination control unit 15-3. The lighting control unit 15-3 sets a short time timer and a long time timer in cooperation with the human sensor 6, and instructs the opening / closing unit 15-4 to turn on / off the lighting load. The opening / closing unit 15-4 controls the lighting load to be turned on / off according to an instruction from the lighting control unit 15-3.
