Description

  The present invention relates to a lighting system that has a general lighting fixture and a local lighting fixture, and controls indoor lighting in cooperation with them.

  In this type of lighting system, general lighting to brighten the entire space such as offices is performed with general lighting equipment from the ceiling, etc., and the lighting required for visual work on the table top surface etc. is from a short distance such as a desk lamp. By using a local lighting fixture, energy saving is achieved by reducing the number of general lighting fixtures and the illuminance.

  As this kind of lighting system, the interior space is generally illuminated, and when the presence of the user at the table is detected by a human sensor, a plurality of local lighting devices including the table in the illumination area are turned on. Is known (see, for example, Patent Document 1). However, although this system can save energy, for example, when the user enters a room that is turned off, the user needs to look for a lighting switch to turn on the general lighting. Even if the general lighting equipment is turned on, it is difficult to find the seating position or the like on the table immediately when the general lighting equipment is turned on when the illumination intensity is low for energy saving or the lighting area of the general lighting equipment is wide.

  Moreover, the local illumination light by the local illumination fixture 2 makes light intensity stronger than the general illumination light by the general illumination fixture 1, and the light color can be different from the general illumination light as described above. The general lighting device 1 and the local lighting device 2 are integrated with, for example, a plurality of light sources. The light sources are turned on and off for general lighting and local lighting, and the light distribution variable function is provided for the local lighting light source. For example, the general illumination and the local illumination may be properly used.

  As the human detection sensor 3, an image sensor of a CCD image sensor, a thermal image sensor, an infrared sensor, or the like can be mainly used. The human detection sensor 3 is disposed on the ceiling surface, the general lighting device 1, or the like, and outside the lighting area of the general lighting device 1. And whether or not there is a person in each of the inner areas, and transmits the person detection information to the control unit 4. Here, the human detection sensor 3 uses a high-sensitivity, wide-band image sensor that has sensitivity even in the near-infrared region as a sensor that can determine the presence of a person even in the dark (for example, when the light is off). The human detection sensor 3 is desirably mounted with a wide-angle lens or a fish-eye lens in order to look down on a wider area.

  The control unit 4 includes a microcomputer for lighting control and a storage device 5 that stores human detection information from the human detection sensor 3, and is arranged on the ceiling surface or the general lighting fixture 1 or the like. The storage device 5 stores image data based on the human detection information from the human detection sensor 3. The storage device 5 may be built in the control unit 4 or integrated with the human detection sensor 3.

  Here, the control unit 4 stores image data in the absence of a person in the storage device 5 for each predetermined detection area of the human detection sensor 3, and the image data stored in the past and the current image data are stored. Are compared in time series to analyze human detection information and determine the presence / absence of a person for each detection area. In addition, the control part 4 can also detect a person's positional information from the image data of person detection information. When the control unit 4 determines the presence / absence of a person, the control unit 4 sends blinking, dimming, and toning signals to the general lighting device 1 and the local lighting device 2, and the human detection sensor 3 detects the lighting area of the general lighting device 1. When a person is detected in the outer area, the general lighting apparatus 1 is turned on. When a person is detected in the inner area of the lighting area, the local lighting apparatus 2 is turned on.

  FIG. 2 shows an arrangement configuration of the general lighting fixture 1, the two local lighting fixtures 2 (2a, 2b), and the human detection sensor 3 in the present lighting system. The general lighting fixture 1 has a circle line type fluorescent lamp light source, and the local lighting fixture 2 has a spherical light source covered with a small conical cover for providing light distribution. These luminaires 1 and 2 are both provided on a disk-like support 6 and covered with an entire cover 7 such as a glove made of a light transmitting material. Further, the human detection sensor 3 is mounted on the periphery of the support 6 and, as described above, includes a semiconductor image sensor such as a high-sensitivity CCD image sensor that can detect a human even in the dark.

  FIG. 3 shows a state in which the lighting system is mounted on the ceiling surface 100 of the indoor space. The general lighting fixture 1 forms the lighting area 11, and the local lighting fixtures 2 a, 2 b form the lighting areas 21, 22. The human detection sensor 3 forms a human detection area 30 (31, 32).

  The illumination area 11 of the general lighting apparatus 1 is a relatively wide area that illuminates the indoor floor surface 101 with a circle line fluorescent lamp, and the lighting areas 21 and 22 of the local lighting apparatuses 2a and 2b are Each of the illumination areas 11 is a narrow predetermined area.

  The human detection sensor 3 includes a single image sensor, and detects a detection area 31 for detecting a person in the area within the illumination area 11 and a person outside the illumination area 11 up to the vicinity of the entrance 102 of the indoor space. And a wide human detection area 30 including a detection area 32 for the purpose. The storage device 5 (not shown) stores in advance image data when no person is present in each of the detection areas 31 and 32 and the illumination areas 21 and 22. Based on the detection of the presence / absence of a person in the detection areas 31 and 32, the control unit 4 detects which area the person is in. When the person is detected in the detection area 32, the general lighting apparatus 1 is automatically detected. When the person is detected in the detection area 31, the one close to the position of the detected person is turned on among the illumination areas 21 and 22 of the local lighting fixtures 2a and 2b.

  Illumination control in the case where the present illumination system configured as described above is applied to a dining room or the like in a house will be described with reference to FIGS. Here, before the user M1 enters the diving room, the general lighting apparatus 1 is in a state of being turned off. Note that the chair on which the user M1 is seated is not shown.

  FIG. 4A shows lighting control when the user (person) M1 enters the dining room and is in the vicinity of the entrance 102. FIG. Here, since the user M1 is located in the outer area of the illumination area 11 of the general lighting apparatus 1, when the person detection sensor 3 detects the user M1 in the detection area 32, the person detection that there is a person in the outer area of the illumination area 11 Generate information. Based on this person detection information, the control unit 4 turns on the illumination area 11 of the general lighting device 1. At this time, the interior of the illumination area 11 including the table 200 is illuminated, so that the user M1 can be guided to the direction of the table 200 while being aware of the table 200.

  Next, FIG. 4B shows the lighting control when the user M1 is guided to the general lighting and enters the inner area of the lighting area 11. Here, when the user M1 enters the inner area of the illumination area 11, the human detection sensor 3 generates human detection information based on the presence of the user M1 detected in the illumination area 11 and its position information. Based on the person detection information, the control unit 4 turns on the local lighting device 2a having the illumination area 21 located near the detected user M1. Here, the illumination area 21 is disposed so as to locally illuminate a predetermined area on the table 200.

  In the illumination area 21, lighting by the local luminaire 2a is added in the illumination area 11 of the general illumination that is already lit, and a light pool that is locally brightened is formed. Here, the local illumination has a light distribution that is more drastic than the general illumination, and the light pool is brightened so that the user M1 can easily recognize it. Therefore, the user M1 is conscious of the bright light pool on the table 200 due to the illumination area 21, and is thus guided to sit in the vicinity of the illumination area 21 of the table 200.

  Next, FIG. 4C shows the illumination control when a new user M2 enters the inner area of the illumination area 11. Here, since the user M1 is already in the illumination area 11, the general lighting apparatus 1 is in a lit state. At this time, when the human detection sensor 3 detects the second user M2 in the illumination area 11, the control unit 4 determines the illumination area 22 located nearby from the position information of the user M2 detected by the human detection sensor 3. The 2nd local lighting fixture 2b which it has is lighted. As the illumination area 22 is turned on, a new light pool is added on the table 200 so that the user M2 recognizes the light, as described above, so that the user M2 is guided to sit near the illumination area 22 of the table 200. Is done.

  As described above, according to the lighting system according to the present embodiment, the general lighting device 1 and the local lighting device 2 are turned on based on human detection, so that each of the areas outside and inside the lighting area 11 of the general lighting device 1 is turned on. A person who is present can be made aware of the lighting areas 11 and 21 sequentially. Thereby, a person outside the illumination area 11 can be easily guided into the illumination area 11 and further to a predetermined area by the illumination area 21. Therefore, it becomes easy to find the table direction and the seating position where the user M1 who enters the room sits. In addition, the two-stage lighting in which individual local lighting is added to the general lighting can produce a “hospitality” for the user M1, and an emotional lighting effect can be obtained.

  Moreover, in the lighting area 11 of one general lighting fixture 1, the lighting area 21 and 22 of the local lighting by two or more local lighting fixtures 2 (2a, 2b) is formed, and thereby it is possible for a plurality of users M1 and M2 In contrast, the same induction effect and “hospitality” can be produced. Note that when the users M1 and M2 are guided into the illumination area 11, the image sensor detects that each user is seated on the table 200, and then the lighting service is increased by making the lighting of the local lighting fixtures 2a and 2b brighter. May be emphasized.

  FIG. 5 shows a modification of the above embodiment. In the present modification, the human detection sensor 3 does not cover the entire human detection area 30 with one sensor, but a human detection sensor 3a for detecting the detection area 32 in the outer area of the illumination area 11, and the illumination And a human detection sensor 3b for detecting the detection area 31 in the inner region of the area 11. Here, for example, the human detection sensor 3a uses an infrared sensor that easily detects a person even in the dark, and the human detection sensor 3b uses an image sensor that detects a person mainly in a bright state when the general lighting apparatus 1 is lit. This makes it possible to detect a person with higher sensitivity when the room is turned off, and does not require an expensive high-sensitivity image sensor for darkness.

  In addition, this invention is not limited to the structure of the said various embodiment, A various deformation | transformation is possible suitably in the range which does not change the meaning of invention. For example, in each of the above-described embodiments, a case where only one illumination area 11 is generally illuminated with one general lighting fixture 1 is shown, but a plurality of general lighting fixtures 1 are used to generalize a plurality of indoor lighting areas 11. It may be illuminated. In addition, although the general lighting device 1 and the local lighting device 2 are turned on in two steps, the lighting service may be provided in three steps or more by adding a narrow range of lighting. In addition to ordinary homes, lighting control can be performed in the same manner as described above in non-residential facilities such as offices, schools, hospitals, stores, and restaurants.
