Embodiment approach 1

[0030] figure 1 It is a block diagram showing the lighting control device according to Embodiment 1 of the present invention.

[0031] figure 2 is shown by figure 1 An explanatory diagram of the relationship between the lighting controlled by the lighting control device and the position of the seats in the floor.

[0032] exist figure 2 In the example of , Lighting 1 is represented by a vertical □, and Seat 2 is represented by ○.

[0033] exist figure 1 Among them, the motion detection device 3 is arranged near the entrance and exit of the floor, or in the floor, and is an action to detect motion. The property information of entering a room or leaving a room from a floor) is sent to the device of the control device 4 .

[0034] The control device 4 is connected to the network of the same system as the dynamic detection device 3, and is capable of receiving the dynamic detection signal sent from the dynamic detection device 3, and sending a control command indicating th...

Embodiment approach 2

[0107] In the above-mentioned first embodiment, it was shown that the control target lighting setting unit 17 sets the same dimming levels of the in-seat and the out-of-seat lighting 1 in all the lighting 1 whose lighting IDs are recorded in the control table, and sets the The dimming level is recorded in the control table, but it is also possible to calculate the distance between the user's seat 2 and the control object lighting 1, set the dimming level corresponding to the distance in the seat and in the seat, and set the This dimming level is recorded in the control table.

[0108] Figure 10 is a configuration diagram showing the control device 4 of the lighting control device according to Embodiment 2 of the present invention, and in the figure, the image 3 The same symbols denote the same or corresponding parts, and thus descriptions thereof are omitted.

[0109] The correspondence relationship storage unit 21 is composed of a storage device such as a RAM or a hard di...

Embodiment approach 3

[0133] In Embodiments 1 and 2 above, the control area of ​​the lighting 1 centered on the user's seat 2 is specified from among the themes selected by the selection accepting unit 15, and the lighting 1 existing in the control area is controlled. However, if multiple users select a desired theme, if the positions of seats 2 of multiple users are close to each other, a part of multiple control areas determined from multiple themes may overlap, Illumination 1 present in overlapping portions of a plurality of control areas is repeatedly set as control-target lighting by the control-target lighting setting unit 17 (or the control-target lighting setting unit 22 ).

[0134] Figure 13 is an explanatory diagram showing a case where part of two control areas overlap, and in Figure 13 In the example, repeat in 2 parts.

[0135] In this third embodiment, the dimming level of the lighting 1 repeatedly set as the lighting to be controlled is set as follows.

[0136] Here, for conveni...

Abstract

The invention provides a lighting control device capable of satisfying slight requirements of each user to improve comfortability of the user. The lighting control device is provided with a lighting control area determining part (16) determining a control area centering as a seat (2) of the user according to the position of the seat (2) of the user and a theme chosen by a selection accepting part (15); a control object lighting determining part (17) determining the lighting (1) in the control area determined by the lighting control area determining part (16) and setting the lighting (1) as the lighting of the control object; and an on-seat judging part (18) judging that whether the user is on the seat or not. A dimming level control part (19) controls the dimming level of the lighting (1) of the control object determined by the control object lighting determining part (17) according to a judgement result of the on-seat judging part (18).

Description

technical field [0001] The present invention relates to a lighting control device for controlling the dimming level of lighting in each floor of a building. Background technique [0002] In recent years, in order to minimize the power consumption of lighting installed on each floor of a building, there has been proposed a lighting control device having a structure that detects an area where there is no one and does not need to turn on the lighting, and only minimizes the necessary lighting. Limited lighting is turned on at the minimum dimming level necessary. [0003] For example, in the lighting control device disclosed in Patent Document 1 below, a detection sensor installed in the lighting detects movement, determines the seat where a person is sitting, and only lights up the lighting installed on the seat, thereby reducing power consumption. [0004] However, in this lighting control device, when the seats of the occupants are sparsely located on the floor, only the lig...
