DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a lighting device of the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected and demonstrated to the part corresponding to the part demonstrated by the prior art example.
[0012]
As shown in FIG. 4, the illuminating device 1 is provided with a reflector 3 in the fixture body 2, and two pairs of lamp sockets 4 are arranged at both ends of the reflector 3. Two straight-tube fluorescent lamps 5 are provided.
[0013]
Further, the reflection plate 3 is a human sensor as a human body detecting means for detecting whether or not there is a human body in a detection area inside a circle in a predetermined range below the instrument main body 2, for example, presence or absence. 6 is disposed.
[0014]
As shown in FIG. 1, the lighting device 1 includes a lighting device 11 such as an inverter circuit that is connected to a commercial AC power source e and turns on and off the fluorescent lamp 5 with all light and dimming. A control unit 12 as a control means for controlling 11 is connected. The control unit 12 has a first signal input unit 12a and a second signal input unit 12b, and the first signal input unit 12a has a human sensor 6 attached to the instrument body 2. Is connected, and a human sensor 6 mounted on another instrument body 2 is connected to the second signal input portion 12b.
[0015]
Further, the lighting state of the fluorescent lamp 5 can be made different between when the signal is input to the first signal input unit 12a and when the signal is input to the second signal input unit 12b. When a signal is input to the first signal input unit 12a, the fluorescent lamp 5 is turned on all the time. When a signal is input to the second signal input unit 12b, the fluorescent lamp 5 is turned on. Further, the control unit 12 controls the fluorescent lamp 5 with priority given to the signal input of the first signal input unit 12a over the signal input of the second signal input unit 12b. In any case, the illuminance may be arbitrarily set without being limited to all-light lighting or dimming lighting.
[0016]
When there is no signal input to either the first signal input unit 12a or the second signal input unit 12b, the control unit 12 causes the fluorescent lamp 5 to be dimmed or extinguished.
[0017]
Further, the lighting device 1 is arranged in a matrix as shown in FIG. 2, for example, and the human sensor 6 of the lighting device 1 adjacent in the vertical or horizontal direction is connected to the second signal input portion 12b. Similarly, the human sensor 6 of the three illuminating devices 1 is connected to the illuminating device 1 arranged at the periphery, and the human sensor 6 of the two illuminating devices 1 is similarly connected to the illuminating device 1 arranged at the corner. It is connected.
[0018]
And if a seating is detected within the detection area of the human sensor 6 of the corresponding lighting device 1, the corresponding lighting device 1 that has been detected by the human sensor 6 of the own appliance body 2 is turned on, and the other The corresponding lighting device 1 that detects presence by the human sensor 6 of the appliance main body 2 is dimmed, and the other lighting devices 1 that do not detect other seating remain off or in a dimmed state.
[0019]
For this reason, for example, even if there is no person at the B point, the lighting device 1 including the human sensor 6 having the detection area at the B point is turned on according to the output from the human sensor 6 having the detection area at the A point. However, the lighting device 1 to which the signal of the human sensor 6 having the detection area at the point A is not input is turned on / off or dimmed depending on the presence / absence of a person in the corresponding detection area.
[0020]
For this reason, when there is a person at the point A, as shown in FIG. 3, the lighting device 1 including the human sensor 6 having the detection area at the point A receives the first signal from the human sensor 6 at the point A. The lighting device 1 including the human sensor 6 having the B point as a detection area when the person is at the B point adjacent to the A point is input to the signal input unit 12a and is turned on. The lighting device 1 provided with the human sensor 6 having the B point as a detection area is dimmed by the human sensor 6 at the point A. Since the lighting device 1 having the human sensor having the detection point B as the detection area is turned on or dimmed, the illuminance at the point A does not change greatly depending on the presence or absence of the person at the point B, so that the feeling of incongruity is hardly given and energy saving is achieved. While making it difficult to feel discomfort. When there is a person at the B point, a signal is input from the human sensor 6 having the B point as the detection area to the second signal input unit 12b of the lighting device 1 having the human sensor 6 having the A point as the detection area. However, since a signal is input from the human sensor 6 to the first signal input unit 12a, the signal to the first signal input unit 12a has priority. The illuminating device 1 provided with the sensation sensor 6 lights up in all light.
[0021]
According to the embodiment described above, the lighting device 1 controls the fluorescent lamp 5 to be all-lighted or dimmed not only by the human sensor 6 of the own lighting device 1 but also by the human sensor 6 of the adjacent lighting device 1. Thus, without providing a new human sensor 6 or the like, the unnecessary lighting device 1 is dimmed or extinguished to save power and become a delicate lighting space suitable for the environment.
[0022]
【The invention's effect】
