The lighting device 1 includes a lighting device 3 for lighting a lamp L, and a control device 4 for controlling the lighting device 3. One human sensor 5 is connected to the control device 4. The motion sensor 5 uses, for example, a passive infrared detection method that detects the motion of the human body. If the motion of the human body is detected within the detection range of the motion sensor 5,
A signal is output from the motion sensor 5, and the control device 4 controls the lighting device 3 to turn on the lamp L. On the other hand, there is no motion of the human body within the detection range of the human sensor 5, and the human sensor 5

In FIG. 1, reference numeral 11 denotes an illuminating device. The illuminating device 11 includes a lamp L such as a fluorescent lamp as a light source, and a lighting device 12 including an inverter circuit for illuminating the lamp L at a high frequency. The lamp L and the lighting device 12 constitute illumination means. The lighting device 12 is connected to a control device 15 as control means. The control device 15 can also be called a sensor control device, and power is supplied to the control device 15 and the lighting device 12 from a commercial AC power supply E.

Further, a first motion sensor 21 and a second motion sensor 22 are connected to the control device 15.
The human sensor 21 and the second human sensor 22 constitute a human sensor 23. The first human sensor 21 and the second human sensor 22 have different detection ranges, but are arranged to detect, that is, detect the presence of a person in the same direction. That is, as shown in FIG. 2, the detection range of the first human sensor 21 is a first detection range A indicated by a dotted line, and the detection range of the second human sensor 22 is a second detection line indicated by a double line. Assuming that the detection range is B, the second detection range B
Is set to include the first detection range A and be wider than the first detection range A. Note that the detection range can be called a detection zone or a detection area.

When the first human sensor 21 and the second human sensor 22 detect the presence of a person, a signal is output from the first human sensor 21 and the second human sensor 22. Is input to the control device 15. Then, the control device 15 controls the lighting device 12 under the preset conditions, and controls the dimming of the output of the lamp L. Also, this dimming control
In addition to switching control of lighting and extinguishing, the lighting frequency of high frequency lighting is changed by an external signal input from the control device 15 to the lighting device 12, for example, a pulse width modulation (PWM) signal, and the output of the lamp L is stepwise or It is designed to change to an unspecified floor.

Next, the operation of the lighting device 11 will be described with reference to FIG.

First, when a person is only at the place 1 in the figure,
The first motion sensor 21 does not output a signal because it is outside the detection range, and the second motion sensor 22 outputs a signal because it is within the detection range. In this case, since the distance between the person and the lamp L as the light source is large, the control device 15
Send a signal to output the maximum.

When a person is only at the location 2 in the figure,
Since the first human sensor 21 and the second human sensor 22 are within the detection range, both output signals. In this case, since the distance between the person and the lamp L, which is a light source, is short, the control device 15 instructs the lighting device 12 to perform pulse width modulation in accordance with a predetermined setting so that the output of the lamp L becomes a dimmed and dimmed output. Send a signal.

According to this embodiment, a lighting control device for controlling a lighting output based on a signal detected by a human sensor for detecting the movement or presence of a human body is provided. The detection direction of the first human sensor 21 and the second human sensor 22 is set in the same direction using the human sensor device 23 including the two human sensors 22 and the detection range of each other is set. A state in which a person is present in the first detection range A close to the lamp L due to the difference in size, and a state in which a person is present outside the first detection range A and far from the lamp L and in the second detection range B Can be distinguished from each other, the output can be controlled over a wide range with a simple configuration, and the light can be delicately controlled by controlling the output of the lamp L, and illumination can be efficiently realized. That is, when no person is present, the lamp L is turned off. When the person is near the lamp L, the lamp L is dimmed to save power. When a person is located far from the lamp, the lamp L is turned off. The required illuminance can be secured by increasing the output of L.
