DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device for automatically controlling the lighting state of a lighting using a human sensor.

[0002]

2. Description of the Related Art FIG. 18 shows a configuration diagram of a conventional lighting device. The lighting device 11p is a so-called sensor-equipped lighting device, and includes a lamp 111, a lighting circuit unit 112 for lighting the lamp 111, and power supply to the lighting circuit unit 112 in accordance with a blink signal from a control unit 115p described later. A human output sensor 1 comprising a load output unit 113 to be controlled and a pyroelectric element for detecting the presence or absence of a person within a predetermined detection range
14 and a control unit 115p that controls the lamp 111 via the load output unit 113 and the lighting circuit unit 112.

FIG. 19 shows a flowchart executed by the control unit shown in FIG. In FIG. 19, when the power is turned on, initialization is performed in order to measure a predetermined time T11 (S900), and then, as a process of mode A, a lighting process of the lamp 111 is performed (S90).
1) As a result, the lamp 111 is turned on.

After that, a predetermined time T11 is counted (S902), and if the predetermined time T11 has not elapsed (S9).
02, N), the process returns to step S902, and the predetermined time T11
Has elapsed (Y in S902), the lamp 111 is turned off (S903), whereby the lamp 111 is turned off.

[0005] Thereafter, as a process of the mode B, it is determined whether or not a detection result indicating the presence of a person is obtained (there is an input) from the motion sensor 114 (S904). When there is an input (Y in S904), the lighting process of the lamp 111 is performed (S905), whereby the lamp 111 is turned on. Thereafter, the counter of the lighting holding time is cleared (S
906), the lighting holding time is counted (S90)
7). On the other hand, if there is no input (N in S904), the process proceeds to step S907.

[0006] Thereafter, it is determined whether or not the lighting hold time has elapsed (S908), and if it has not elapsed (S908).
N), the process returns to step S904, and if it elapses (S90)
Then, the lamp 111 is turned off (S90).
9) As a result, the lamp 111 is turned off. After this,
It returns to step S904.

In the lighting device 11p having the above configuration and operation, when the power is turned on as shown in FIG.
1) During a predetermined time T11, the lamp 111 is turned on, and at a time point t102 when the predetermined time T11 has elapsed, the lamp 111 is once turned off. Thereafter, when the presence sensor 114 detects the presence of a person (t103), The lamp 111 is turned on for a predetermined lighting holding time from the time point t103, and the lighting holding time is updated every time the presence of a person is detected by the human sensor 114 (see t104).

Thus, during the predetermined time T11, the lamp 1
The reason for forcibly turning on 11 is that the operation of the pyroelectric element is unstable for about several tens of seconds from the time of turning on the power, and the human sensor 114 constituted by the pyroelectric element determines whether or not there is a person. Instead, by outputting a detection signal indicating the presence of a person.
Therefore, conventionally, the predetermined time T11 is set to the human sensor 1
14 is set to about 30 seconds necessary for normal detection operation, and while the human sensor 114 cannot accurately detect the presence or absence of a person, the lamp 111 is forcibly turned on as a mode A. This prevents a malfunction from occurring. When the human sensor 114 can accurately detect the presence or absence of a person, the mode A is switched to the mode B in which the automatic lighting control of the lamp 111 is performed according to the detection result of the human sensor 114. Can be

[0009]

However, in the above-described lighting device, as shown in FIG.
If a person is present in the detection range of the human sensor 114 for a while after the elapse of the predetermined time T11 from the predetermined time T11, the predetermined time T11
During the period from the time point t112 when the presence sensor is detected by the human sensor 114 to the time point t113, the lamp 111 is turned off.

In order to solve such a problem, as shown in FIG. 22, control is performed such that a predetermined lighting holding time always starts from a time point t122 at which a predetermined time T11 has elapsed irrespective of the detection result of the human sensor 114. May be adopted. However, in this control, as shown in FIG. 22, the detection range of the human sensor 114 is from the time point t121 at which the power is turned on to the time point t123 at which the lighting hold time started at the time point t122 at which the predetermined time T11 elapses. There is another problem that the lamp 111 is turned on even when no person is present. As described above, if the lamp 111 is turned on even when no person exists, useless power is consumed.

The present invention has been made in view of the above circumstances, and can prevent useless power consumption.
Even if a person is present in the detection range, the lighting shifts to automatic lighting (light control) control of the lighting load according to the detection result of the human sensor without temporarily turning off (or turning on the lower limit) the lighting load. It is intended to provide a device.

According to this configuration, even when the lighting load is switched to the lighting as the lower limit when a person is in the detection range, the lighting sensor is detected by the human sensor while the lighting level of the lighting load is gradually decreasing. By performing a desired operation, it becomes possible to return the lighting level of the lighting load to the lighting level as the upper limit before lowering to the lighting level as the lower limit. In addition, since the degree of increase in the fade-in level is constant, the sense of discomfort in switching from lighting as the lower limit to lighting as the upper limit is reduced.

Further, the lighting device according to any one of claims 1 to 5 and 7, further comprising a selection means for selecting a lighting level as an upper limit with respect to the lighting load, and lighting as an upper limit selected by the selection means. When the level is switched to a lighting level as a lower limit lower than this, the lighting level of the lighting load is lowered by fading out, and the lighting level as the lower limit is switched to a lighting level as an upper limit selected by the selection means. In this case, the lighting level of the lighting load rises with a fade-in, and the degree of decrease of the fade-out level becomes constant irrespective of the lighting level selected by the selection means, and the time of the fade-in is determined by the selection means. The configuration may be constant regardless of the selected lighting level (claim 9). According to this configuration, when the lighting load switches from lighting as the upper limit to lighting as the lower limit, the amount of change in light per unit time is constant, so that the strangeness of the change in light to a nearby person is reduced. Further, when the lighting load switches from lighting as the lower limit to lighting as the upper limit, the switching is performed in a fixed time, so that a sense of discomfort with respect to the difference in the fade-in time during lighting as the upper limit is reduced.
