Embodiment approach 1

[0027] The lighting system 2 involved in this embodiment is as figure 1 As shown, there are a lighting control device 1 according to this embodiment, a plurality (five units in the illustrated example) of lighting loads Ln (n=1, 2, ..., 5) and a plurality (2 in the illustrated example) Taiwan) human sensor Sm (m = 1, 2). However, the number of lighting loads Ln is not limited to five, and the number of human detection sensors Sm is not limited to two.

[0028] Lighting load Ln e.g. figure 2 As shown, it is an LED lighting fixture including an LED module 30 as a light source, a lighting circuit unit 31 , a power supply circuit unit 32 , a lighting control unit 33 , and the like. The LED module 30 preferably consists of, for example, a series circuit of a plurality of white light emitting diodes. The power circuit unit 32 preferably converts an AC voltage supplied from a commercial AC power supply (electric power system) 6 into a DC voltage. For example, the power cir...

Embodiment approach 2

[0063] The lighting control device 1 according to the present embodiment has the same configuration as the lighting control device 1 according to the first embodiment. In addition, the lighting system 2 which concerns on this embodiment has the same structure as the lighting system 2 which concerns on Embodiment 1 except the point which does not provide the timer circuit 43 to the human detection sensor Sm. Therefore, among the configurations of the lighting control device 1 and the lighting system 2 according to the present embodiment, the same configurations as those of the lighting control device 1 and the lighting system 2 according to the first embodiment are denoted by the same symbols and illustrations and descriptions are omitted.

[0064] Next, refer to Figure 10 and Figure 11 The flowchart of the lighting control device 1 and the lighting system 2 are described in detail.

[0065] Initially, it is assumed that neither of the two human detection sensors S1...

Abstract

The invention provides an illumination control apparatus, an illumination system and an illumination control method. When a human sensing signal of another human-sensing sensor (S2) is input into a human-sensing sensor (S1) within second retention time, a control part (10) of the illumination control apparatus (1) selects the scene data preferably based on the input human sensing signal relative to the second retention time. As a result, during time t=t6-t7, a scene number 2 is switched into a scene number 3. On the other hand, in a comparison case that the scene data is not selected preferably based on the input human sensing signal relative to the second retention time, in a short time period in the time t=t6-t7, the scene number 2 is switched into a scene number 1, then the scene number 1 is switched into the scene number 3. Thus, the illumination control apparatus (1) can prevent unnecessary and frequent switching of the illumination environment (scene).

Description

technical field [0001] The present invention relates to a lighting control device, a lighting system, and a lighting control method. More specifically, it relates to a lighting control device that controls a lighting load according to the presence or absence of people, a lighting system including the lighting control device and a lighting load, and The lighting control device is a lighting control method for controlling lighting loads. Background technique [0002] For example, the load control device described in Japanese Patent Application Laid-Open No. 2008-10370 includes a control unit, a human sensor, a hold timer, and the like. The human sensor is configured to sense the presence of a human using infrared rays emitted from the human body, and output the sensing result to the control unit. The control unit controls the hold timer to measure an elapsed time after the presence of a person is detected by the human detection sensor. In addition, the control unit resets th...
