[0025] Hereinafter, a method for adjusting the car lighting device 50 of the elevator 10 of the present invention will be described with reference to the drawings.

[0026] Fig. 1 is an explanatory diagram showing the schematic configuration of an elevator 10 according to one embodiment of the present invention. Note that only functions related to the present invention are shown in the figure. The elevator 10 is configured by disposing a car 30 in a shaft 12 that penetrates a building 11 so that the car 30 can ascend and descend.

[0027] The car 30 in which passengers board has a car door 31 through which passengers enter and exit. The car door 31 is automatically opened and closed by an opening and closing device 32.

[0028] A machine room 13 provided, for example, at the top of the shaft 12, houses a hoisting machine 14 and a brake 15. The hoisting machine 14 is provided with the brake 15 and a sheave 16 that rotates by the hoisting machine 14, and a deflection pulley 17 is provided in parallel with the sheave 16. A main rope 18 is hung between the sheave 16 and the deflection pulley 17. One end of the main rope 18 is supported by a car 30, and the other end is supported by a counterweight 19 for suspension.

[0029] Further, in the shaft 12, landing doors 21 leading to landings 20 on each floor of the building 11 are arranged, allowing communication between the inside of the shaft 12 and each landing 20. In normal operation, the hoist 14 is driven to raise and lower the car 30, and the car 30 is stopped at the landing 20 on a predetermined floor and the opening / closing device 32 is operated, whereby the landing doors 21 are opened and closed in conjunction with the opening and closing of the car doors 31.

[0030] At the landing 20 and the car 30, operation panels 22, 33 are arranged, which allow passengers to perform various operations such as landing calls, car calls, and door opening and closing.

[0031] The elevator 10 is controlled by an operation control unit 41 provided in the machine room 13 and a car control unit 42 provided in the car 30. Fig. 2 is a control block diagram of the main parts of the elevator 10. The operation control unit 41 controls the raising and lowering of the car 30, i.e., the hoist 14 and the brake 15, in response to car calls from the operation panels 22, 33, for example. The car control unit 42 also controls the opening and closing device 32, etc. In the present invention, the operation control unit 41, the car control unit 42, and the lighting control unit 43, which will be described next, are collectively referred to as the control device 40.

[0032] A car lighting device 50 is disposed inside the car 30. The car lighting device 50 can employ a light source such as an LED or an organic LED whose color temperature and brightness are adjustable. The car lighting device 50 can be disposed on the ceiling of the car 30, for example, as shown in FIG. 3. The car lighting device 50 is controlled by commands for on / off, color temperature, and brightness from a lighting control unit 43 shown in FIG. 2. The color temperature of the car lighting device 50 is synonymous with the color temperature reproduced inside the car 30, and by adjusting the color temperature of the car lighting device 50, the color temperature reproduced inside the car 30 can also be adjusted. Furthermore, by adjusting the brightness (luminous flux) of the car lighting device 50, the illuminance inside the car 30 illuminated by the car lighting device 50 can be adjusted.

[0033] More specifically, the lighting control unit 43 adjusts the color temperature and brightness of the car lighting device 50 based on parameters acquired by an acquisition unit 60 described next, thereby adjusting the color temperature and illuminance reproduced inside the car 30. The lighting control unit 43 has a storage unit 44 that stores a table in which parameters are associated with the color temperature and illuminance reproduced inside the car 30. A specific example of the table will be described later, but the lighting control unit 43 adjusts the color temperature and brightness of the car lighting device 50 so that the color temperature and illuminance inside the car 30 are reproduced at predetermined values. Note that the table may store, instead of the color temperature and illuminance inside the car 30, the color temperature and brightness of the car lighting device 50 required to achieve these.

[0034] An acquisition unit 60 that acquires parameters related to the elevator 10 is disposed in the elevator 10 .

[0035] The parameters related to the elevator 10 include, for example, the temperature inside the car, the outside air temperature of the environment where the elevator 10 is installed, the passenger ratio inside the car 30 (car floor occupancy rate), etc. The parameters are not limited to these, and in the embodiment, in addition to these, the illuminance of the hall 20 where the car 30 will next stop, the color of the belongings of the passenger boarding the car 30, and the solar altitude in the area where the elevator 10 is installed are listed.

[0036] The acquisition unit 60 is a sensor or the like according to the parameter. Specifically, when the parameter is the temperature inside the car, it is an in-car temperature sensor 61 (FIGS. 2 and 3) installed inside the car 30, when the parameter is the outside air temperature, it is an outside air temperature sensor 62 (FIGS. 1 and 2) installed outside the building 11, when the parameter is the outside air temperature, it is an occupancy ratio detection sensor 63 (FIGS. 2 and 3) that detects the occupancy ratio of passengers inside the car 30, etc. The occupancy ratio detection sensor 63 is, for example, a weight sensor 63a (FIGS. 1 and 2) that measures the load of the car 30.

[0037] In the present invention, based on the parameters related to the elevator 10 acquired by the acquisition unit 60, the lighting control unit 43 adjusts the color temperature and brightness of the car lighting device 50 so that the illuminance and color temperature inside the car 30 are reproduced.

[0038] For example, when the parameter is the inside-car temperature, the inside-car temperature sensor 61 is electrically connected to the lighting control unit 43. A table, such as Table 1 described below, that associates the inside-car temperature with the color temperature and illuminance reproduced in the car 30 is stored in the memory unit 44 of the lighting control unit 43. Then, the lighting control unit 43 reads out from the table the color temperature and illuminance corresponding to the inside-car temperature acquired by the inside-car temperature sensor 61, and adjusts the color temperature and brightness of the car lighting device 50 so that this color temperature and illuminance are reproduced.

[0039] The color temperature inside the car 30 and the illuminance for that color temperature can be set based on the psychological effect (Kluzoff effect) on the color temperature and illuminance of lighting. Figure 4 shows the Kluzoff effect. The Kluzoff effect shows a psychological effect in which the horizontal axis is color temperature (K) and the vertical axis is illuminance (lx), and when the color temperature and illuminance are within the comfort zone between the comfort curves shown in the figure (Kluzoff's comfort zone, "comfort zone" in Figure 4), a person feels comfortable, but when they are outside the comfort zone, a person feels uncomfortable.

[0040] For example, in the Kruzov effect, a color temperature of 3300K or less is considered to be a warm color, a color temperature of 5300K or more is considered to be a cold color, and a color temperature of 3300K to 5300K is considered to be an intermediate color. Also, an illuminance higher than the comfort zone is considered to be hot and uncomfortable, and an illuminance lower than the comfort zone is considered to be gloomy, dark, and cold, which also causes discomfort. For this reason, as described later in the embodiment of Table 1, the lighting control unit 43 adjusts the color temperature and brightness of the car lighting device 50 so that the color temperature and illuminance reproduced in the car 30 are 2700K and 100lx when the temperature inside the car is less than 18°C, 3800K and 500lx when the temperature inside the car is 18°C ​​or more and less than 28°C, and 7000K and 4000lx when the temperature inside the car is 28°C or more. Although the Kluzoff comfort zone has a certain width, the color temperature and illuminance reproduced in the car 30 and stored in the table of the memory unit 44 need only be within the comfort zone, and it is more preferable that they are at the midpoint of the Kluzoff comfort curve (shown by the straight line in FIG. 4).

[0041] Based on the Kruzov effect, by adjusting the color temperature and illuminance reproduced inside the car 30 corresponding to the parameter (temperature inside the car) as described above, when the temperature inside the car is low, passengers feel warmer due to the warm-colored lighting, and when the temperature inside the car is high, passengers feel cooler due to the cool-colored lighting, allowing them to ride in the car 30 comfortably.

[0042] Since it is desirable to adjust the color temperature and illuminance reproduced inside the car 30 in a gradual logarithmic change, it is preferable to adjust the color temperature and brightness of the car lighting device 50 in a gradual logarithmic change so as not to cause passengers to feel uncomfortable. EXAMPLES

[0043] Various examples of elevator-related parameters are given below, and the color temperature and brightness of the car lighting device 50 are adjusted accordingly so that the color temperature and illuminance inside the car 30 become desired values. Note that although various numerical values ​​are specified in this specification for explanation, these numerical values ​​are all merely examples.

[0044] <Example 1> The parameter is the temperature inside the car, and the color temperature and illuminance reproduced inside the car 30 are adjusted based on the temperature inside the car.

[0045] The acquisition unit 60 is an in-car temperature sensor 61 that measures the temperature inside the car 30, and is electrically connected to the lighting control unit 43 (FIGS. 2 and 3). The in-car temperature sensor 61 may be disposed inside the car 30, or, if a temperature sensor is mounted on an air conditioning mechanism such as an air conditioner, that temperature sensor can be used. For example, the temperature measurement can be performed each time the door of the car 30 is opened or closed.

[0046] Table 1 shows the relationship between the temperature inside the car and the color temperature and illuminance reproduced inside the car 30. In Table 1, the temperature inside the car is divided into three temperature ranges, and examples of optimal adjustment contents and specific setting values ​​for each temperature range are shown. The temperature ranges are not limited to three, as long as there are two or more ranges, and the color temperature and illuminance may be changed linearly with respect to each temperature.

[0047] [Table 1]

[0048] In Table 1, when the temperature inside the car is in the low temperature range, the color temperature is lowered and the illuminance is adjusted in accordance with the Kluzoff effect based on the color temperature (color temperature 2700K, illuminance 100lx), and when the temperature is in the high temperature range, the color temperature is raised and the illuminance is adjusted in accordance with the Kluzoff effect based on the color temperature (color temperature 7000K, illuminance 4000lx).

[0049] For the intermediate temperature range, that is, between 18°C ​​and 28°C, as an example, the illuminance inside the car 30 is set to 500lx as specified in JIS Z 9110:2010, and the color temperature is adjusted based on that illuminance in accordance with the Kluzoff effect (3800K). According to the "examples of values ​​reproduced inside the car" listed in Table 1, the color temperature and brightness of the car lighting device 50 are adjusted so that the color temperature and illuminance reproduced inside the car 30 can be realized. In the table, the adjustment content of the car lighting device 50 is shown in the "lighting adjustment content". When the illuminance reproduced inside the car 30 is as specified in the JIS standard (500lx), the column for the brightness of the car lighting device 50 states "no change", and when the brightness of the car lighting device 50 is adjusted based on the color temperature reproduced inside the car 30, it states "adjusted according to the Kluzoff effect based on the car color temperature". When the color temperature of the car lighting device 50 is adjusted based on the illuminance reproduced in the car 30, it is described as "adjusted according to the Kruzov effect based on the car illuminance." The same applies to the following examples.

[0050] According to the first embodiment, when the temperature inside the car is low, below 18°C, the passengers feel warm due to the warm-toned lighting, and when the temperature inside the car is high, above 28°C, the passengers feel cool due to the cool-toned lighting, so that they can ride in the car 30 comfortably.

[0051] <Example 2> In the second embodiment, the outside air temperature of the environment in which the elevator 10 is installed is adopted as a parameter, and the color temperature and illuminance reproduced inside the car 30 are adjusted based on the outside air temperature.

[0052] The acquisition unit 60 is an outside air temperature sensor 62 that is provided outside the building 11 and measures the outside air temperature, and is electrically connected to the lighting control unit 43 (FIGS. 1 and 2).

[0053] Table 2 shows the correspondence relationship between the outside air temperature and the color temperature and illuminance reproduced inside the car 30. In Table 1, the temperature inside the car is divided into three temperature ranges, and examples of optimal adjustment contents and specific setting values ​​for each temperature range are shown. Of course, the temperature ranges are not limited to three as long as there are two or more, and the color temperature and illuminance may be changed linearly with respect to each temperature.

[0054] [Table 2]

[0055] In Table 2, in the low temperature range of the outside air temperature, the color temperature is lowered and the illuminance is adjusted according to the Kluzoff effect based on the color temperature (color temperature 2800K, illuminance 150lx), and in the high temperature range, the color temperature is raised and the illuminance is adjusted according to the Kluzoff effect based on the color temperature (color temperature 6000K, illuminance 3000lx).

[0056] In the intermediate temperature range, i.e., between 0°C and 25°C, the illuminance of the cage 30 is set to, for example, an illuminance that satisfies the JIS standard, and the color temperature is adjusted based on the illuminance in accordance with the Kruzov effect (color temperature 3800K, illuminance 500lx).

[0057] According to the second embodiment, when the outside temperature is below 0°C, the passengers feel warm due to the warm-toned lighting, and when the outside temperature is 25°C or higher, the passengers feel cool due to the cool-toned lighting, so that they can ride in the cage 30 comfortably.

[0058] <Example 3> In the third embodiment, the temperature inside the car and the season are adopted as parameters, and the color temperature and illuminance reproduced inside the car 30 are adjusted in response to these.

[0059] As with the first embodiment, the car temperature is measured by using a car temperature sensor 61 as the acquisition unit 60. The seasons are determined by referring to a clock function installed in the control device 40, etc., and are meteorological seasons, for example, March to May is spring, June to August is summer, September to November is autumn, and December to February is winter. Specific embodiments are shown in Table 3.

[0060] In Table 3, the car lighting device 50 is adjusted so that the color temperature and illuminance inside the car 30 are reproduced according to the adjustment method of the present invention only when the season is high in summer and low in winter. For other relatively comfortable periods such as low temperatures in summer and high temperatures in winter, and in spring and winter, the car lighting device 50, for example, sets the illuminance reproduced in the car 30 to a brightness that satisfies the JIS standard, and adjusts the color temperature according to the Kruzov effect based on the illuminance reproduced in the car 30.

[0061] [Table 3]

[0062] Specifically, summer and winter are divided into two temperature ranges, with 28°C as the boundary. In summer, when the temperature inside the car is high, at or above 28°C, cool lighting with a high color temperature and illuminance is reproduced inside the car 30, giving a cool feeling. In winter, when the temperature inside the car is low, at or below 28°C, warm lighting with a low color temperature and illuminance is reproduced, giving a warm feeling. This allows passengers to ride in the car 30 comfortably.

[0063] <Example 4> In the fourth embodiment, the passenger occupancy rate in the car 30 is used as a parameter. The acquisition unit 60 for detecting the passenger occupancy rate is a passenger occupancy rate detection sensor 63, which can be, for example, a weight sensor 63a (FIGS. 1 and 2) for detecting the load in the car 30 or a camera 63b (FIGS. 2 and 3) for photographing the degree of congestion in the car 30. The weight sensor 63a can detect the passenger occupancy rate and the car floor occupancy rate based on the load in the car 30. The camera 63b can photograph the inside of the car 30 and detect the passenger occupancy rate and the car floor occupancy rate by image analysis. For example, when the passenger occupancy rate is the car floor occupancy rate Y, as shown in Table 4, the passenger occupancy rate can be defined as four levels of the car floor occupancy rate Y, 0 to 37%, more than 37% and less than 67%, more than 67% and less than 97%, and more than 97%. The definition of the passenger occupancy rate for each level is as shown in Table 4.

[0064] [Table 4]

[0065] The lighting control unit 43 adjusts the color temperature and brightness of the car lighting device 50 so that the color temperature and illuminance inside the car 30 are reproduced according to the level of the passenger occupancy rate (car floor occupancy rate Y) obtained from the passenger occupancy rate detection sensor 63 in Table 4. Generally, the higher the passenger occupancy rate inside the car 30, the more uncomfortable the passenger feels. For this reason, in this embodiment, as shown in Table 5, when the passenger occupancy rate reaches levels 3 and 4, the color temperature and illuminance reproduced inside the car 30 are adjusted according to the adjustment method of the present invention. The color temperature and brightness of the car lighting device 50 are adjusted according to the Kluzoff effect. On the other hand, at levels 2 and below, the passenger occupancy rate is low, so the illuminance reproduced inside the car 30 is set to, for example, an illuminance that satisfies the JIS standard, and the color temperature is adjusted according to the Kluzoff effect based on the illuminance.

[0066] [Table 5]

[0067] According to this embodiment, the higher the occupancy rate of the car 30, the cooler the lighting reproduced inside the car 30 is, with a higher color temperature and illuminance, so that the passengers can feel cooler. This allows the passengers to ride in the car 30 comfortably.

[0068] <Example 5> In this embodiment, the illuminance and temperature of the landing 20 are adopted as parameters to adjust the color temperature and illuminance reproduced inside the car 30. The acquisition unit 60 includes an illuminance sensor 64 that measures the illuminance of the landing 20, and a landing temperature sensor 65 that measures the temperature of the landing 20. The landing 20 is the landing where the car 30 will next stop.

[0069] It is desirable to install the illuminance sensor 64 at a height of about 1.5 m (at the height of an adult's head to neck) near the jamb on three sides of the landing door 21. The illuminance sensor 64 may not be able to measure the illuminance correctly due to shadows from passengers, etc. For this reason, it is desirable to install multiple illuminance sensors 64 at the landing 20, and have the lighting control unit 43 determine the illuminance of the landing 20 by excluding outliers from the obtained measured values.

[0070] It is also desirable to install the landing temperature sensor 65 at a position near the jamb of the landing door 21 at a height of about 1.5 m.

[0071] The illuminance sensor 64 and the hall temperature sensor 65 measure the illuminance and hall temperature of the hall 20 of the floor where the car will stop next in response to a car call or a hall call, and transmit the results to the lighting control unit 43. For example, when a passenger gets on the car 30 and the door closes, the lighting control unit 43 refers to the illuminance and hall temperature of the hall 20 of the floor where the car will stop next, and based on the illuminance and hall temperature, changes the color temperature and brightness of the car lighting device 50 so that the color temperature and illuminance inside the car 30 are reproduced, while ascending or descending to the hall 20 of the floor where the car will stop next. Specifically, when the car moves to the third floor in response to a car call after opening the door on the first floor, the illuminance and hall temperature measured by the illuminance sensor 64 and the hall temperature sensor 65 on the third floor are referred to after the door closes on the first floor. Then, the lighting control unit 43 changes the color temperature and brightness of the car lighting device 50 before the car 30 arrives at the third floor.

[0072] In addition, when the car 30 continues to land at the same landing 20 for a long time (for example, 3 hours) after the door is closed, such as at night, the illuminance and landing temperature of the landing 20 often change. For this reason, taking into consideration that the car control unit 42 receives a door-opening signal at the same floor, the illuminance and landing temperature of the landing 20 can be remeasured at regular intervals, and the color temperature and illuminance reproduced in the car 30 can be changed each time. In addition, when the car control unit 42 receives a door-opening signal at the same floor, the lighting control unit 43 may refer to the illuminance and landing temperature of the landing 20 again, and change the color temperature and illuminance reproduced in the car 30 by the time the door is opened. Of course, when there is a landing call at another floor, the illuminance and landing temperature of the landing 20 are measured while moving to that floor, and the color temperature and brightness of the car lighting device 50 may be changed so that the color temperature and illuminance in the car 30 are adjusted before the car 30 lands on the floor.

[0073] Incidentally, installing an illuminance sensor 64 and a landing temperature sensor 65 at each landing 20 incurs costs. For this reason, the illuminance and landing temperature may be measured when the elevator 10 is newly installed, and the car lighting device 50 may be controlled so that the color temperature and illuminance reproduced inside the car 30 are adjusted based on the measured illuminance and landing temperature. Then, the illuminance and temperature of each landing 20 may be measured again at the time of regular maintenance, and corrections may be made. In this case, an illuminance sensor and a landing temperature sensor may be brought into each landing 20 at the time of installation and maintenance, and measurements may be taken in sequence, so only one sensor per landing may be required.

[0074] In addition to the illuminance and hall temperature of each hall 20, the color temperature and illuminance reproduced inside the car 30 can also be adjusted by combining the car interior temperature shown in the first embodiment.

[0075] <Example 6> In this embodiment, the parameter is the color including the passenger's luggage (hereinafter referred to as "passenger's color"). The acquisition unit 60 is a color measurement sensor 66, for example a camera 63b. The lighting control unit 43 extracts pixels of the passenger and luggage from an image captured by the camera, for example, and makes a judgment based on information regarding the color of the pixels. If the pixel is treated as information of 256 gradations of RGB, the passenger's color can be the color that is the peak of the gradation.

[0076] The lighting control unit 43 has a table relating to the color tone of the passenger and the color temperature and illuminance reproduced inside the car 30. For example, the table sets the color temperature and illuminance reproduced inside the car 30 to be high to give the interior of the car 30 a calming color tone when the passenger has a dark color tone, and sets the color temperature and illuminance to be low to give the interior of the car 30 a calming color tone when the passenger has a bright color tone.

[0077] Specifically, a camera 63b (color measurement sensor 66: Figs. 2 and 3) is installed inside the car 30, and the lighting control unit 43 judges the color of the passengers by photographing the inside of the car 30. The judgment can be made every time the door is closed. Then, the color temperature and brightness of the car lighting device 50 are adjusted based on the judged color of the passengers.

[0078] As a result, when a passenger with darker skin tones gets in, the entire car will be dominated by dark colors, but a refreshing feeling can be achieved by increasing the color temperature and illuminance, and conversely, when a passenger with lighter skin tones gets in, the color temperature and illuminance reproduced inside the car 30 can be lowered to achieve a calmer feeling.

[0079] The lighting control unit 43 can also adjust the color temperature and illuminance reproduced inside the car 30 according to the color tone of the passengers including their luggage.

[0080] In addition, AI learning can be incorporated to store videos and images of passengers before and after boarding, and the color temperature and illuminance reproduced inside the car 30 can be adjusted so that the changes in color tone caused by passengers boarding are optimal.

[0081] The color temperature and illuminance reproduced inside the car 30 can be adjusted so that the passenger looks beautiful depending on the clothes, accessories, hair color, etc., that the passenger is wearing. For example, the color temperature and illuminance are set high for cool-colored clothes, and low for warm-colored clothes.

[0082] It is desirable for the color measurement sensor 66 to obtain a camera image of the inside of the car 30 when the door is closed, and to distinguish between passengers getting on and off based on the direction of movement of the passengers. Whether a passenger is getting on or off can also be determined by a weight sensor 63a or a photoelectric cell or an infrared sensor that is generally installed on the landing door 21.

[0083] Additionally, extraction of pixels for use in measuring the color tint of the passenger can be performed by comparison with an image of the interior of an unmanned car 30.

[0084] As another embodiment, in an elevator 10 in which a gate 70 and a destination floor registration device 71 are installed at the landing 20 as shown in Fig. 1, a color measurement sensor 66 is disposed near the gate 70 and the destination floor registration device 71. In this embodiment, the color of a passenger passing through the gate 70 and the color of a passenger operating the destination floor registration device 71 are measured in advance and can be used to adjust the color temperature and illuminance reproduced inside the car 30.

[0085] <Example 7> This embodiment adjusts the color temperature and illuminance reproduced inside the car 30 based on the solar altitude in the area where the elevator 10 is installed.

[0086] The acquisition unit 60 is configured to be able to calculate the date, time and solar altitude of the area. The acquisition unit 60 may be one function of the lighting control unit 43.

[0087] The table in the memory unit 44 contains preset values ​​such that, for example, the higher the solar altitude in the area where the elevator 10 is installed, the higher the color temperature and illuminance reproduced inside the car 30 will be, and the lower the solar altitude, the lower the color temperature and illuminance will be. It is also preferable that the color temperature and illuminance be even lower from sunset to sunrise.

[0088] Fig. 5 is a graph of the settings of the table based on the solar altitude on April 1st in Tokyo. The horizontal axis represents time. Sunrise is around 5:28, sunset is around 18:02, and the sun reaches noon at around 11:45. The graph shows the color temperature and illuminance inside the car 30 corresponding to the time.

[0089] By adjusting the color temperature and illuminance reproduced inside the car 30 according to FIG. 5, the color inside the car 30 will be warm from evening to morning, and during the daytime, the color temperature and illuminance are increased to produce a cool color.

[0090] The above description is for the purpose of explaining the present invention, and should not be interpreted as limiting the invention described in the claims or restricting the scope of the invention. Furthermore, the configuration of each part of the present invention is not limited to the above embodiment, and various modifications are possible within the technical scope described in the claims.

[0091] In the above embodiment and example, the color temperature and illuminance to be reproduced inside the car 30 are stored in a table, but the color temperature and brightness of the car lighting device 50 for realizing these color temperatures and illuminance may also be stored in a table.

[0092] Moreover, the car lighting device 50 may be controlled so that the color temperature and illuminance inside the car 30 are realized by combining two or more of the above-described embodiments.

[0093] The color temperature and illuminance reproduced in the car 30 can be adjusted by a maintenance person or a passenger within the comfort zone of the Kruzoff effect shown in Fig. 4 by displaying a brightness bar on the operation panel 33 or the like. Also, a maintenance person may connect a terminal device to the lighting control unit 43 and use the brightness bar or the like to adjust the color temperature and illuminance reproduced in the car 30 within the comfort zone of the Kruzoff effect shown in Fig. 4.
