DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] In an embodiment of the present disclosure, a lighting system is proposed that includes a plurality of downlights provided on the underside of a roof of a carport, which is an example of a parking space, so as to make a vehicle parked in the carport look more attractive.

[0011] Conventional carport lighting did not take into account people's aesthetics or emotional evaluations. This is believed to be because no technology had been established for accurately analyzing people's sensory evaluations. The inventors established a technology for accurately analyzing people's sensory evaluations, and used the analysis technology to analyze subjects' sensory evaluations obtained through experiments on the installation positions and number of downlights. The installation positions, number, and illuminance of downlights that can make vehicles parked in carports look more attractive will be described based on the analysis results of the experiments.

[0012] 1 shows the configuration of a lighting system according to an embodiment. The lighting system 1 includes downlights 10a, 10b, 10c, 10d, 10e, and 10f (hereinafter collectively referred to as "downlights 10"), a nameplate light 11, a gate light 12, a planting light 13, a control device 50 that controls the brightness of at least some of these lights, and a communication network 40 that connects these lights and the control device 50.

[0013] The nameplate lamp 11 is provided on a gate sleeve 7 provided near the entrance 3, which is the entrance between the exterior and interior of the building 2.

[0014] The sleeve light 12 is provided near the lower part of the sleeve 7 and indirectly illuminates the space around the sleeve 7 by illuminating the sleeve 7.

[0015] The plant light 13 is provided near the bottom of a plant 8 provided in the passage 4 leading from the gate sleeve 7 to the entrance 3, and indirectly illuminates the space near the passage 4 by illuminating the plant 8.

[0016] The downlights 10 are provided in a plurality of rows along the front-rear direction of a vehicle 6 on the underside of the roof of a carport 5 provided near a gate sleeve 7, and illuminate the vehicle 6 parked in the carport 5 and the space near the carport 5.

[0017] [Carport lighting] A technique for illuminating the vehicle 6 so that the vehicle 6 looks more attractive using downlights 10 provided on the underside of the roof of the carport 5 will be described.

[0018] Figures 2 and 3 show examples of installation positions of the downlight 10. Figure 2 is a view of the carport 5 seen from above. Figure 3 is a view of the carport 5 seen from the front. The circle in Figure 2 and the triangle in Figure 3 typically show the lighting range of the downlight 10. In Figure 2, the small inner circle shows the lighting range at a height of 1 m from the ground, and the large outer circle shows the lighting range on the ground.

[0019] The downlights 10 include downlights 10a, 10b which illuminate the vicinity of both left and right ends of the front end 6a of a vehicle 6 parked in a carport 5, downlights 10e, 10f which illuminate the vicinity of both left and right ends of the rear end 6b of the vehicle 6, and downlights 10c, 10d which illuminate the vicinity of the left and right sides of a middle portion 6c between the front end 6a and the rear end 6b of the vehicle 6.

[0020] The front end 6a of the vehicle 6 may be a region from the front end of the vehicle 6 to the vicinity of the headlight 6d. The front end 6a of the vehicle 6 may be a region from the front end of the vehicle 6 to 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 15%, 20%, 25%, or 30% of the total length of the vehicle 6. The rear end 6b of the vehicle 6 may be a region from the rear end of the vehicle 6 to the vicinity of the tail lamp 6e. The rear end 6b of the vehicle 6 may be a region from the rear end of the vehicle 6 to 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 15%, 20%, 25%, or 30% of the total length of the vehicle 6. The middle portion 6c of the vehicle 6 may be a region excluding the front end 6a and the rear end 6b of the vehicle 6. The downlights 10c and 10d may be provided so as to illuminate the vicinity of the center of the vehicle 6 in the longitudinal direction (front-rear direction).

[0021] The downlights 10a and 10b may be provided in an area from the front end of the roof of the carport 5 to the rear end of the front end 6a of the vehicle 6. The downlights 10e and 10f may be provided in an area from the rear end of the roof of the carport 5 to the front end of the rear end 6b of the vehicle 6. The downlights 10c and 10d may be provided near the center of the carport 5 in the longitudinal direction.

[0022] At least a part of the downlight 10 may be provided outside the periphery of the vehicle 6 parked in the carport 5. This allows the side of the vehicle 6 to be effectively illuminated, making the vehicle 6 look more attractive. The optical axis of the downlight 10 may be directed vertically downward or may be inclined toward the side of the vehicle 6.

[0023] At least a part of the downlight 10 may be provided near the outer periphery of the vehicle 6 on the inner side of the outer periphery. The downlight 10 may be provided in an area from the outer periphery of the vehicle 6 to 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 15%, 20%, 25%, or 30% of the vehicle width of the vehicle 6. It is more preferable that the downlight 10 is provided in an area from the outer periphery of the vehicle 6 to 5% to 15% of the vehicle width of the vehicle 6. This allows the side of the vehicle 6 to be effectively illuminated, making the vehicle 6 look more attractive. The optical axis of the downlight 10 may be vertically downward or inclined toward the outer periphery of the vehicle 6.

[0024] The downlights 10a and 10b may be provided at intervals of 1500 mm or more. The downlights 10a and 10b may be provided at intervals of 1400 mm or more, 1450 mm or more, 1550 mm or more, 1600 mm or more, 1650 mm or more, 1700 mm or more, 1750 mm or more, or 1800 mm or more. The downlights 10a and 10b may be provided at intervals wider than the vehicle width of the front end of a typical vehicle. This allows the side of the vehicle 6 to be effectively illuminated, making the vehicle 6 look more attractive.

[0025] The downlights 10e and 10f may be provided at intervals of 1500 mm or more. The downlights 10e and 10f may be provided at intervals of 1400 mm or more, 1450 mm or more, 1550 mm or more, 1600 mm or more, 1650 mm or more, 1700 mm or more, 1750 mm or more, or 1800 mm or more. The downlights 10e and 10f may be provided at intervals wider than the vehicle width of the rear end of a typical vehicle. This allows the side of the vehicle 6 to be effectively illuminated, making the vehicle 6 look more attractive.

[0026] The downlights 10c and 10d may be provided at intervals of 1500 mm or more. The downlights 10c and 10d may be provided at intervals of 1400 mm or more, 1450 mm or more, 1550 mm or more, 1600 mm or more, 1650 mm or more, 1700 mm or more, 1750 mm or more, or 1800 mm or more. The downlights 10c and 10d may be provided at intervals wider than the vehicle width of the middle part of a general vehicle. This allows the side of the vehicle 6 to be effectively illuminated, making the vehicle 6 look more attractive.

[0027] The downlights 10a and 10b, the downlights 10c and 10d, and the downlights 10e and 10f may be provided in pairs on the left and right at the same position in the longitudinal direction of the vehicle 6.

[0028] The downlights 10 may be provided in parallel with equal widths in the front-rear direction of the vehicle 6, or some of the downlights 10 may be provided with widths different from the other downlights 10.

[0029] The downlights 10c, 10d for illuminating the middle part 6c of the vehicle 6 may be provided at a position farther away from the central axis 6f in the longitudinal direction of the vehicle 6 than the downlights 10a, 10b for illuminating the front end part 6a of the vehicle 6 or the downlights 10e, 10f for illuminating the rear end part 6b of the vehicle 6. In general, the width of the vehicle 6 is wider near the center in the longitudinal direction than the front end part 6a and the rear end part 6b. Therefore, by providing the downlights 10c, 10d for illuminating the middle part 6c of the vehicle 6 further outward, the side surface of the middle part 6c of the vehicle 6 can be illuminated more effectively, making the vehicle 6 look more attractive.

[0030] When the roof of the carport 5 is composed of a plurality of elongated long members 61 whose longitudinal direction is the longitudinal direction of the carport 5, the downlights 10c and 10d may be provided on the long member 61 adjacent to the outer side of the long member 61 on which the downlights 10a, 10b, 10e, or 10f are provided. The downlights 10c and 10d may be provided on the long member 61 two or more positions away from the outer side of the long member 61 on which the downlights 10a, 10b, 10e, or 10f are provided. The plurality of long members 61 are supported by a support column only on one side in the left-right direction (the left side in FIG. 3). The plurality of long members 61 may be supported by a support column only at the rear. The plurality of long members 61 are inclined in the left-right direction. In FIG. 3, the left side is inclined so that the left side is lower. The plurality of long members 61 may be inclined in the front-rear direction. The roof of the carport 5 may be composed of a plurality of long and narrow members whose short sides coincide with the longitudinal direction of the carport 5. A more detailed configuration of the carport 5 will be described later with reference to FIG.

[0031] The downlights 10c and 10d may be provided at an interval of 0 mm or more wider than the interval between the downlights 10a and 10b or the downlights 10e and 10f, and 300 mm or less. The downlights 10c and 10d may be provided at an interval of 5 mm or more, 10 mm or more, 20 mm or more, 30 mm or more, 40 mm or more, 50 mm or more, 100 mm or more, 150 mm or more, 200 mm or more, 250 mm or more, or 300 mm or more wider than the interval between the downlights 10a and 10b or the downlights 10e and 10f. This allows the side surface of the middle portion 6c of the vehicle 6 to be effectively illuminated, making the vehicle 6 look more attractive. The downlights 10c and 10d may be provided at the same interval as the interval between the downlights 10a and 10b or the downlights 10e and 10f. The downlights 10c and 10d, the downlights 10a and 10b, and the downlights 10e and 10f may be provided in series at the same intervals.

[0032] The installation intervals and installation positions of the downlights 10 may be adjusted according to the size of the carport 5 and the size, shape, width, length, etc. of the vehicle 6 parked in the carport 5. However, the downlights 10 are preferably provided near the inner periphery of the vehicle 6 or outside the periphery, and more preferably outside the periphery of the vehicle 6. This makes the vehicle 6 look more attractive.

[0033] The number of downlights 10 installed may be six as shown in Fig. 2, or may be five or less, or may be seven or more. Instead of or in addition to the downlights 10, line lights that illuminate linearly may be provided.

[0034] The downlights 10 may be provided near the ground of the carport 5 such that a part of the vehicle 6 is located within 10 to 40% of the illumination range of each downlight 10 (the range of the large circle in FIG. 2). The downlights 10 may be provided at a height of 1 m above the ground of the carport 5 such that a part of the vehicle 6 is located within 0 to 40% of the illumination range of each downlight 10 (the range of the small circle in FIG. 2).

[0035] In the case where the roof of the carport 5 is inclined in order to allow rainwater and the like accumulated on the upper surface of the roof of the carport 5 to fall, the downlight 10 may be provided so that its optical axis is inclined toward the vehicle 6. The downlight 10 may be provided so that its optical axis is approximately perpendicular to the inclination of the roof of the carport 5, or so that its optical axis is approximately perpendicular to the ground.

[0036] The carport 5 may be configured to park a plurality of vehicles 6. In this case, the carport 5 may be configured to park a plurality of vehicles 6 side by side, or may be configured to park a plurality of vehicles 6 vertically. When the carport 5 is configured to park a plurality of vehicles 6 side by side, the downlights 10 provided in the outermost rows on both the left and right sides when the plurality of vehicles 6 are parked side by side are arranged so that the intervals near the center are wider than the front and rear ends, making the vehicles 6 look more attractive.

[0037] The downlight 10 may be controlled to gradually light up when a human is detected by a human sensor installed near the building 2. This can give the occupant a sense of being greeted by the vehicle 6 when entering the building 2, enhancing emotionality. Furthermore, the downlight 10 is turned on when an intruder is detected, enhancing crime prevention. In this case, the lighting system 1 further includes a human sensor. The control device 50 acquires the detection result by the human sensor and controls the downlight 10. The human sensor may be installed near the entrance of the carport 5, near the gate of the building 2, near the gate sleeve 7, or the like. The control device 50 may set the fade-in time from when a human is detected by the human sensor to when the downlight 10 is turned on 100% to 1.5 seconds. The fade-in time may be 1 second, 1.5 seconds, 2 seconds, 2.5 seconds, or 3 seconds. The fade-in time may be adjusted according to the relative positions of the entrance 3, passageway 4, carport 5, gate sill 7, gate, etc. of the building 2, the installation position of the motion sensor, the age, sex, walking speed of the occupants, etc.

[0038] The downlights 10 may be turned on during standby when no people are detected around the carport 5. The control device 50 may turn on the downlights 10 at 10% illuminance during standby. This allows the vehicle 6 to look more attractive even during standby. The illuminance of the downlights 10 during standby may be 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, or 50%.

[0039] By providing the downlights 10 as described above, the side of the vehicle 6 parked in the carport 5 can be illuminated more effectively, making the vehicle 6 look more attractive. In addition, the surroundings of the vehicle 6 can also be illuminated effectively, reducing dark areas where light does not reach, improving crime prevention. In addition, a warm light effect can be provided, enhancing emotional appeal.

[0040] 4 shows the configuration of a carport 5. The carport 5 comprises a pair of posts 22 (pillars) erected on the ground 21, a beam 24 extending from the upper end of the posts 22 in a direction intersecting the posts, a roof body 26 connected to the lower part of the beam 24, a pair of roof body side cover members 28 (cover members), and a roof body tip cover member 65. The posts 22 and the beam 24 are formed from extruded shapes of aluminum material, and have a hollow structure with a hollow section.

[0041] The pair of pillars 22 are arranged on one side of the carport 5 in the left-right direction, spaced apart in the front-to-rear direction of the carport 5.

[0042] The pair of beams 24 are disposed at a distance from each other in the front-rear direction of the carport 5. Each of the pair of beams 24 extends in the left-right direction and is formed with a downward slope toward the support pillar 22. The base end side ends (right end parts) of the pair of beams 24 are connected to the upper ends of the support pillars 22 via L-shaped connecting members. The roof body 26 is connected to the lower parts of the pair of beams 24.

[0043] The roof body 26 has a hanging structure in which the roof body 26 is suspended from the lower parts of a pair of beams 24, and is attached (connected) to the lower parts of the pair of beams 24. The roof body 26 is configured by a plurality of long members (long members) 61 that are arranged side by side in the direction in which the beams 24 extend and are fitted and connected to each other.

[0044] Each of the long members 61 extends in the front-rear direction of the carport 5 (the direction perpendicular to the direction in which the beams 24 extend) and has a predetermined thickness. Each of the long members 61 is formed of an extruded aluminum material, and has a hollow structure with a hollow section formed in a hollow shape. The roof body 26 has an upper surface 26a and a lower surface 26b formed flat (planar). The roof body 26 is arranged on a downward slope with the support 22 side descending, and the upper surface 26a and the lower surface 26b are formed on a downward slope with the support 22 side descending. By connecting the long members 61 formed of an extruded aluminum material to form the roof body 26, the long members 61 can be used as a surface material of the roof body 26 and the strength of the roof body 26 can be ensured. Furthermore, by configuring the multiple long members 61 constituting the roof body 26 from members having hollow portions, the roof body 26 itself can be used as a strength member, and there is no need to provide a separate member for increasing the strength of the roof body 26. This allows the number of parts constituting the roof body 26 to be reduced. The long members 61 may have one or more holes in which the downlights 10 can be placed. Furthermore, each wiring of the downlights 10 may pass through the hollow portions of the long members 61 and be connected to a power supply unit.

[0045] [Lighting around the building] We will explain lighting technology around buildings that can enhance emotional appeal while improving crime prevention.

[0046] The gate sleeve lights 12 and planter lights 13 indirectly illuminate the space around the building 2, particularly the space near the entrance 3, by illuminating tall structures such as the gate sleeve 7 and planters 8. By appropriately setting the illuminance of these lights, it is possible to provide a warm and emotional lighting effect for residents and passersby, while providing a level of brightness that can discourage suspicious people from entering the building 2 or allow the suspicious people to be identified if they do enter the building 2.

[0047] Fig. 5 shows another example of the configuration of the lighting system according to the embodiment. The lighting system 1 shown in Fig. 5 includes a foot lamp 14 that illuminates the ground near the entrance 3, instead of the entrance lamp 12 and the planting lamp 13 of the lighting system 1 shown in Fig. 1.

[0048] The footlights 14 illuminate the ground or floor, thereby indirectly illuminating the space around the building 2, particularly the space near the entrance 3. By appropriately setting the illuminance of these lights, it is possible to provide a warm and emotional lighting effect for residents and passersby, while providing a level of brightness that can make a suspicious person give up on entering the building 2 or to identify the suspicious person if he or she does enter the building 2.

[0049] The gate lamps 12, plant lamps 13, and foot lamps 14 may be provided in any combination. For example, all of these lights may be provided, or only one of them may be provided. In addition to these lights, further lights may be provided around the building 2.

[0050] The average luminance around building 2 is 0.4 cd / m 2 It is preferable to illuminate the building so that the average luminance around the building 2 is 0.1 cd / m 2 More than 0.2cd / m 2 More than 0.3cd / m 2 More than 0.4cd / m 2 More than 0.5cd / m 2 More than 0.6cd / m 2 More than 0.7cd / m 2 More than 0.8cd / m 2 More than 0.9cd / m 2 More than 1cd / m 2 More than 1.5cd / m 2 More than 2cd / m 2 More than 2.5cd / m 2 More than 3cd / m 2 It may be more than that.

[0051] It is preferable to illuminate the area around the building 2 so that the illuminance at a position near the face of a person is 1.2 lux or more. The illuminance at a position near the face of a person may be 1 lux or more, 1.1 lux or more, 1.2 lux or more, 1.3 lux or more, 1.4 lux or more, 1.5 lux or more, 1.6 lux or more, 1.7 lux or more, 1.8 lux or more, 1.9 lux or more, 2 lux or more, 2.5 lux or more, 3 lux or more, 3.5 lux or more, 4 lux or more, 4.5 lux or more, 5 lux or more, 5.5 lux or more, or 6 lux or more.

[0052] The average luminance on the ground around building 2, especially near entrance 3, is 1.5 cd / m 2 It is preferable to illuminate the building so that the average luminance on the ground around the building 2 is 1 cd / m 2 More than 1.1cd / m 2 More than 1.2cd / m 2 More than 1.3cd / m 2 More than 1.4cd / m 2 More than 1 / 5cd / m 2 More than 1.6cd / m 2 More than 1.7cd / m 2 More than 1.8cd / m 2 Above, 1.9cd / m 2 More than 2cd / m 2 More than 2.5cd / m 2 More than 3cd / m 2 It may be more than that.

[0053] It is preferable to illuminate the ground of the carport 5 so that the illuminance on the ground is 5.3 lux or more. The illuminance on the ground of the carport 5 may be 1 lux or more, 1.1 lux or more, 1.2 lux or more, 1.3 lux or more, 1.4 lux or more, 1.5 lux or more, 1.6 lux or more, 1.7 lux or more, 1.8 lux or more, 1.9 lux or more, 2 lux or more, 2.5 lux or more, 3 lux or more, 3.5 lux or more, 4 lux or more, 4.5 lux or more, 5 lux or more, 5.5 lux or more, or 6 lux or more.

[0054] The lighting system 1 of the present embodiment can reduce dark areas where light does not reach, improving crime prevention. It can also provide a warm light effect, enhancing emotional impact.

[0055] [Evaluation experiment 1] In a test site simulating an ordinary house, subjects' evaluations of a downlight 10 in a carport 5 were analyzed.

[0056] [Evaluation experiment 1-1: Relationship between the number and location of downlights and the aesthetic appearance of the vehicle] In the experimental site shown in FIG. 1, the relationship between the number and installation positions of the downlights 10 in the carport 5 and the aesthetic appearance of the vehicle 6 was investigated. The subjects' evaluations were analyzed in the following cases: (1) when the downlights 10 were installed in three locations, namely, the center positions of the downlights 10a and 10b, the center positions of the downlights 10c and 10d, and the center positions of the downlights 10e and 10f; (2) when four downlights 10a, 10b, 10e, and 10f were installed; (3) when six downlights 10a, 10b, 10c, 10d, 10e, and 10f were installed in parallel with equal widths; (4) when six downlights 10a, 10b, 10c, 10d, 10e, and 10f were installed with a wide interval between the downlights 10c and 10d (installation positions shown in FIG. 2); and (5) when two line lights were installed at the left and right ends of the carport 5.

[0057] FIG. 6 shows the analysis results. In the cases of (3) and (4), more subjects felt that the car was "bright in color," "clear in outline," "the car had a three-dimensional feel," "the car looked cool," "I wanted to keep looking at the car," "bright," "luxurious," "elegant," "eye-catching," "dramatic," and "good taste" than in the cases of (1) and (2). Therefore, it is preferable to install six downlights 10 rather than three or four. In the case of (4), more subjects felt that the car had a three-dimensional feel, "the car looked cool," "luxurious," and "elegant" than in the case of (3). Therefore, it is preferable that the installation width of the downlights 10c and 10d that illuminate the middle part of the vehicle 6 is wider than the downlights 10a, 10b, 10e, and 10f that illuminate the front and rear ends. In the case of (5), more subjects felt that the car was "eye-catching," "dramatic," and "modern," and it was found that the evaluation of the space including the carport 5 was high when line lights were installed. In contrast, it was found that when six downlights 10 were installed, the evaluation of vehicle 6 was high.

[0058] [Evaluation experiment 1-2: Relationship between downlight illuminance during standby and vehicle aesthetics] The relationship between the illuminance of the lighting during standby when no people are detected around the carport 5 and the aesthetic appearance of the vehicle 6 was investigated. The subjects' evaluations were analyzed for a case in which the downlights 10 were turned off during standby and a case in which the downlights 10 were illuminated at 10% illuminance during standby.

[0059] The analysis results are shown in Figure 7. The subjects rated the downlight 10 at 10% illuminance during standby higher in all items. Therefore, it is preferable to turn on the downlight 10 even during standby.

[0060] [Evaluation experiment 1-3: Relationship between downlight fade-in time and emotional response] A motion sensor was installed near the gate of the building 2 or near the entrance to the carport 5, and as the subject walked from the gate towards the entrance 3, the downlight 10 was gradually turned on after the subject was detected by the motion sensor. The subject's evaluation was analyzed when the fade-in time from when the motion sensor detected the subject to when the downlight 10 was turned on 100% was set to 1.5 seconds and when it was set to 2.5 seconds.

[0061] FIG. 8 shows the analysis results. In either case, many subjects felt that they were welcomed by the downlight 10. Therefore, it is preferable to gradually turn on the downlight 10 when a person is detected. There were differences in the subjects' evaluations for the items "the timing of the light-on and the walking is in sync" and "the light-on time is just right." In the experimental site shown in FIG. 1, the highest evaluation was achieved when the human sensor was installed at the gate and the fade-in time was set to 1.5 seconds. The installation position of the human sensor and the fade-in time may be adjusted according to the relative positions of the gate, entrance 3, passage 4, carport 5, etc. in the building 2.

[0062] In this manner, it has been shown that the lighting system 1 of the present embodiment illuminates the vehicle 6 parked in the carport 5 so as to make it look attractive.

[0063] [Evaluation experiment 2] We investigated the relationship between the combination of lighting such as nameplate lights 11, gate lights 12, planting lights 13, foot lights 14, and down lights 10 and crime prevention. The subjects' evaluations were analyzed in the following cases: (1) when only the nameplate light 11 is installed; (2) when the nameplate light 11, footlight 14, and six downlights 10 are installed, and the fade-in time of the downlights 10 is set to 1.5 seconds; (3) when the nameplate light 11, gate sleeve light 12, planting light 13, and six downlights 10 are installed, and the fade-in time of the downlights 10 is set to 1.5 seconds; (4) when the nameplate light 11, gate sleeve light 12, planting light 13, and six downlights 10 are installed, and the fade-in time of the downlights 10 is set to 0 seconds (no fade-in); (5) when the nameplate light 11, gate sleeve light 12, planting light 13, and six downlights 10 are installed, and the downlights 10 are always on; and (6) when the nameplate light 11, gate sleeve light 12, planting light 13, and three downlights 10 are installed, and the fade-in time of the downlights 10 is set to 1.5 seconds. The subjects' evaluations were analyzed from the viewpoints of the residents, passersby, and intruders. For the viewpoints of the residents, the subjects' evaluations were analyzed for the gate, the entrance 3, and the carport 5.

[0064] [Evaluation experiment 2-1: Residents' line of sight near the gate] Figure 9 shows the results of the analysis. The subjects gave the case of (2) a high rating. It was found that while there is no need to ensure brightness more than necessary in places that are directly visible, direct lighting by footlights 14 or the like gives residents a greater sense of security in areas that are shaded. When the captured images were analyzed and the luminance was measured, the luminance near the gate in case (1) was 0.06 cd / m 2 It was.

[0065] [Evaluation experiment 2-2: Residents' line of sight near the entrance] Figure 10 shows the analysis results. The subjects rated the area in (1) low, and the area in (2) high. It was found that the residents felt more secure in the shadows when the area was directly lit by footlights 14 or the like. The luminance near the entrance in the cases of (3) to (6) was 0.3 cd / m 2 In the case of (2), the luminance near the entrance is 1.5 cd / m 2 It was.

[0066] [Evaluation experiment 2-3: Residents' line of sight near the carport] Figure 11 shows the analysis results. The subjects rated the case (1) low, and the case (2) high. It was found that in the shadows, direct lighting by downlights 10 or the like gives the residents a greater sense of security. The subjects rated the cases (3) to (5) higher than the case (6), and it was found that six downlights 10 provide sufficient brightness and fewer shadows than three downlights 10, giving the residents a greater sense of security. The luminance near the carport in the cases (3) to (6) was 0.30 cd / m 2 It was.

[0067] [Evaluation experiment 2-4: Passersby's line of sight] Figure 12 shows the analysis results. Many respondents said that it is possible to determine the gender and physique even in case (1), because it is generally possible to distinguish the gender and physique from just the outline, but many respondents said that it is not possible to determine in case (1), because sufficient brightness is required to distinguish the clothing and face. In cases (2) to (6), it was found that it is possible to obtain information to identify an intruder, because the space around the entrance 3 is indirectly illuminated by the gate sleeve lamp 12, planter lamp 13, foot lamp 14, etc. The luminance around the person's face is 0.1 cd / m in case (1). 2 and for (3) to (6), it is 0.4 cd / m 2 It was.

[0068] [Evaluation experiment 2-5: Intruder's perspective] Figure 13 shows the analysis results. (7) is the case of (1) with the curtains open (assuming the resident is at home), and (8) is the case of (3) with the curtains open (assuming the resident is at home). In the cases of (1) and (7), many subjects felt that it was easy to break in. In the cases of (2) to (5) and (8), many subjects felt that it was difficult to break in.
