Description

  The present invention relates to an elevator car lighting device, and more particularly to an elevator car lighting device that reduces power consumption during standby operation of an elevator.

  In general, in an elevator, in order to reduce the power consumed by the lighting equipment in the car, all calls that the elevator car should answer are completed and there are no users in the car. An automatic pause operation is performed in which the lighting apparatus is automatically turned off after a predetermined time has elapsed (see Patent Document 1).

  Furthermore, when a fluorescent lamp is used as a lighting fixture in the car, the fluorescent lamp may flicker when the fluorescent lamp is turned off and then turned on again. This flicker phenomenon of the fluorescent lamp may occur. When the user moves in, the user feels uneasy. In order to prevent this discomfort, the function to delay the door opening start time by a fixed time when the door is opened after the automatic pause operation. (See Patent Document 2).

  Originally, if there are no users in the car, it is ideal to turn off the lighting equipment in the car immediately to reduce power consumption. However, to reduce power consumption, the lighting equipment is turned on. Then, the time from turning off to turning off is shortened, and when the user of the car appears again, the lighting fixture is turned on again, so that the number of times of turning off and turning on the lighting increases.

  However, in the technology described in Patent Document 1, in an elevator with an automatic pause operation, the light source of the lighting fixture at that time was an incandescent lamp or a fluorescent lamp. For this reason, if the number of times of turning off and re-lighting the luminaire is increased, the life of the luminaire is shortened, an extra replacement cost of the luminaire is required, and maintenance work is involved, which makes the maintenance inspection work troublesome.

  In addition, when there are many opportunities to relight the luminaire, as a countermeasure against the flicker phenomenon of the luminaire, the door is turned on until the lighting state of the luminaire stabilizes after answering the call as in the technique of Patent Document 2. Since the opening time is delayed, the waiting time until the door is opened is troublesome and inconvenient for the user.

  The present invention has been made in view of the above, and its purpose is to reduce power consumption by quickly turning off the light source of the semiconductor element when there is no user in the elevator car.

The call signal R2 is output to the illumination control circuit 9a.

  The load detector 6 shown in FIG. 2 is installed under the car floor F, and a load signal R3 is output from the load detector 6 to the illumination control circuit 9a. The load detector 6 detects the weight of the user on the car floor F and outputs a load signal R3 to the lighting control circuit 9a, so that the lighting control circuit 9a is used on the car floor F. The number of people is grasped.

  The car call button 7 shown in FIG. 2 is used by the user as an input unit. However, the car call button 7 is provided on the car operation panel 3, and when the car call button 7 is pressed, a call signal R4 is displayed on the car. It is output to the illumination control circuit 9a of the duct 9. The lighting switch 10 is provided on the car operation panel 3, and when an administrator presses the lighting switch 10, for example, an on / off signal R5 of the lighting is output to the input / output circuit 9b of the car upper duct 9, for example.

  In the machine room M shown in FIG. 2, an elevator main control unit 8 is arranged. The main controller 8 supplies power to the illumination control circuit 9a. Information on the above-mentioned call signals R1, R2, load signal R3, call signal R4, and on / off signal R5 is sent to the main control unit 8 via a tail cord connected to the main control unit 8 of the machine room M from the car. By being sent, the car 101 of the elevator 100 shown in FIG. 1 is operated. Call signals R1 and R2 are landing call signals, and call signal R4 is a car call signal. These call signals R1, R2, load signal R3, and call signal R4 are output to the lighting control circuit 9a as a command for turning on and off the lighting fixtures 1R1 to 1R4 of the in-car lighting device 1. Is done.

  Next, the car upper duct 9 shown in FIG. 2 will be described.

  In the car upper duct 9 shown in FIG. 2, the lighting control circuit (substrate) 9a which is a unit for controlling the car lighting device 1 and an input / output circuit 9b are arranged. The illumination control circuit 9a and the input / output circuit 9b are electrically connected. The lighting control circuit 9a is electrically connected to the door control unit 12 in the car upper duct 9, and supplies a door opening / closing signal R6 between the lighting control circuit 9a and the door control unit 12. Thereby, the illumination control circuit 9a can control the opening and closing of the doors DR1 and DR2 of the car 101 shown in FIG. 1 by supplying the door opening / closing signal R6 to the door control unit 12.

  In addition, the input / output circuit 9b and the lighting devices 1R1 to 1R4 of the in-car lighting device 1 in the car ceiling 2 are electrically connected, and the in-car lighting device 1 in the car ceiling 2 is connected from the input / output circuit 9b. A power output R7 can be separately supplied to each of the lighting fixtures 1R1 to 1R4.

  The lighting control circuit 9a shown in FIG. 2 has input conditions for turning on and off the lighting fixtures 1R1 to 1R4 of the in-car lighting device 1 set by the operator operating the external lighting switch 10. The power supply state of the elevator from the main control unit 8 and the commands for turning on and off the lighting fixtures 1R1 to 1R4 based on the above-described call signals R1, R2, load signal R3, and call signal R4 are detected. It is like that.

  And the illumination control circuit 9a is based on the information on the input conditions, the power state of the elevator from the main control unit 8, and the lighting command and the extinguishing command of each lighting fixture 1R1 to 1R4 of the in-car lighting device 1. Through the input / output circuit 9b, the power supply output R7 is supplied to the lighting fixtures 1R1 to 1R4 of the in-car lighting device 1 in the normal state to turn on the lighting fixtures 1R1 to 1R4 of the in-car lighting device 1, and in an emergency. By disconnecting the power output R7 of each of the lighting fixtures 1R1 to 1R4 of the in-car lighting device 1 and turning off the respective lighting fixtures 1R1 to 1R4 of the in-car lighting device 1, the user is prevented from using the elevator. .

  When the administrator operates the lighting switch 10 shown in FIG. 2 to manually release the power output R7 to each of the lighting fixtures 1R1 to 1R4, the lighting fixtures 1R1 to 1R4 of the in-car lighting device 1 are turned off. It can also be made.

  Each of the lighting fixtures 1R1 to 1R4 of the in-car lighting device 1 includes one or a plurality of light sources 30 and resistors, which will be described later. For example, when the disabled person gets on and off the car, On the other hand, it is possible to adopt a configuration that can be switched by a relay contact so that the current value to be supplied is larger than the normal current value. In order to change the amount of light emitted from the light source 30, another light source and resistor unit may be provided, and this unit may be connected in parallel to the light source 30.

  Next, an operation example of turning on and off the lighting fixtures 1R1 to 1R4 of the above-described elevator car lighting device 1 will be described. When explaining an example of the operation of turning on and off the lighting fixtures 1R1 to 1R4 of the elevator car lighting device 1, "lighting control from the start to the end of standby operation (turning on and off)" and "call response operation" The explanation will be divided into “—Lighting control until turning on to the reference floor (turning on and off)”.

  First, “lighting control from start to end of standby operation (lighting and extinguishing)” when the car is waiting on the reference floor of the building will be described.

  FIG. 3 is a flowchart showing “lighting control from start to end of standby operation (lighting and extinguishing)” when the car is waiting on the reference floor of the building. FIG. 4 is a time table showing “lighting control (lighting and extinguishing) from the start to the end of standby operation” when the car is waiting on the reference floor of the building, similarly to the flowchart shown in FIG. It is the figure which compares with the time table of a prior art example.

  First, in FIG. 3, in the case where the automatic pause operation is performed when the car is standing by on the reference floor, the call button on the car operation panel 3 in FIG. If 7 is not pressed and the call signal R4 is not input to the illumination control circuit 9a, that is, if there is no car call, the process proceeds to step S2 in FIG.

  In step S2, the user has not pressed the hall call button 5a on the first floor, the hall call button 5b on the second floor, or the hall call button 5c in FIG. 2, and the call signals R1 and R2 are not input to the illumination control circuit 9a. If there is no state, that is, no hall call, the process proceeds to step S3 in FIG.

  In step S3, when the lighting control circuit 9a detects that the response has been completed without the car call and hall call as described above, the lighting control circuit 9a detects that the doors DR1 and DR2 are completely open based on the opening / closing signal R6 in FIG. Is determined to be closed. In step S3 of FIG. 3, the illumination control circuit 9a starts timer counting. In step S3-1, the lighting control circuit 9a starts in step S4 at a time earlier than the case where a conventional incandescent lamp or fluorescent lamp is used. The 2 lighting fixtures 1R1 to 1R4 are turned off.

  In the embodiment of the present invention, the timer count time of the lighting control circuit 9a is set to about several seconds in consideration of, for example, the time when the user leaves the door, and the lighting fixtures 1R1 to 1R4 can be turned off after about several seconds. This prevents the user from turning off before getting out of the car by preventing the lighting fixtures 1R1 to 1R4 of FIG. And the safety of the user can be ensured.

  Thereafter, in step S5 of FIG. 3, the user presses one of the hall call button 5a on the first floor, the hall call button 5b on the second floor, or the hall call button 5c, and the hall call call signal R1 or call shown in FIG. When the signal R2 is input to the lighting control circuit 9a, the lighting control circuit 9a relights the lighting fixtures 1R1 to 1R4 of the in-car lighting device 1 via the input / output circuit 9b. As described above, when the lighting fixtures 1R1 to 1R4 are turned on again, the lighting up time of each lighting fixture 1R1 to 1R4 is, for example, about 0.2 seconds, and the lighting up time of the light source 30 is incandescent or fluorescent. Faster than the rise time of the relighting.

The above-described illumination control operation shown in FIG. 3 will be described more specifically with reference to FIG.
FIG. 4 (A) shows the operating state of the elevator, FIG. 4 (B) shows the operation of turning on and off each lighting fixture 1R of the in-car lighting device 1 in the embodiment of the present invention, and FIG. ) Shows the operation of turning on and off in a conventional lighting fixture. In the operation state of the elevator car shown in FIG. 4 (A), standby of the elevator car operation is started at time T1, and the standby is ended at time T3.

  In the embodiment of the present invention shown in FIG. 4B, the lighting fixtures 1R1 to 1R4 of the in-car lighting device 1 are turned off at time T1, and are turned off at time T2 after about several seconds have elapsed. . Then, the lighting fixtures 1R1 to 1R4 of the in-car lighting device 1 are turned off at time T4 about 0.2 seconds after time T3.

  On the other hand, in the conventional example shown in FIG. 4C, the light is finally turned off at time T5 after about several minutes to several tens of minutes from the state where the lighting fixture is turned on at time T1. And at the time T3, it will be in the state which turned on again at the time T6 about 2-3 seconds after the state which the lighting fixture was light-extinguished.

  As can be seen by comparing FIG. 4B and FIG. 4C, the lighting fixture of the in-car lighting device 1 of the embodiment of the present invention has a turn-off start time (time T1) as compared with the conventional lighting fixture. Not only can be significantly shortened, but also the lighting start time (between times T3 and T4) can be greatly shortened.

  FIG. 5 is a flowchart showing “lighting control (lighting and extinguishing) from call answering operation to returning to the reference floor”. FIG. 6 compares the time table indicating “lighting control (lighting and extinguishing) from call answering operation to returning to the reference floor” with the time table of the conventional example, similarly to the flowchart shown in FIG. 5. FIG.

  First, starting from step S0 shown in FIG. 5, in step S11, the user presses one of the hall call button 5a on the first floor, the hall call button 5b on the second floor, and the hall call button 5c in FIG. If the signal R1 or the call signal R2 is input to the illumination control circuit 9a, that is, if there is a hall call, the process proceeds to step S12 in FIG.

  In step S12, the user has not pressed the call button 7 of the car operation panel 3 in FIG. 2, and the call signal R4 is not input to the illumination control circuit 9a, that is, there is no car call and the response is completed. If this is detected, the process proceeds to step S13 in FIG. In step S13, the car moves to the response floor while the lighting control circuit 9a continues to turn off the lighting fixtures 1R1 to 1R4 of the in-car lighting device 1.

  Here, the response floor refers to the floor where the user is waiting to call and register in the hall in order to use the elevator.

  Next, in step S14-1 in FIG. 5, the car 101 in FIG. 1 reaches the response floor. After the car 101 has landed on the response floor, in step S14-2, the EL main control unit 8 shown in FIG. 2 outputs an opening / closing signal R6 for opening the doors DR1 and DR2 to the door control unit 12. In step S14-3, the lighting control circuit 9a starts lighting the entire lighting fixtures 1R1 to 1R4 of the in-car lighting device 1. Then, the lighting of the lighting fixtures 1R1 to 1R4 in the car 101 is completed before or immediately after the doors (doors) DR1 and DR2 of the car and the car 101 start to open. Thereby, the inside of the car 101 is brightly illuminated, and the user can get into the car 101 safely.

  Thereafter, in step S15, when a user is placed in the car 101 on the response floor and the user presses the call button 7 in the car 101, the call signal R4 is input to the lighting control circuit 9a. The car 101 moves to the destination registration floor.

  In step S16 of FIG. 5, the number of registered car calls is smaller than the number of registrations set in advance, and the user's load on the car floor detected by the load detector 6 shown in FIG. 2 is greater than the preset load. When the load signal R3 indicating that the load is low is sent to the lighting control circuit 9a, the lighting control circuit 9a determines that the number of users in the car is small, for example, one or two users. Then, the process proceeds to step S17 in FIG.

  In step S17, the lighting control circuit 9a supplies the power output R7 only to the two lighting fixtures 1R1 and 1R2 on the front surface of the lighting fixtures 1R1 to 1R4 of the in-car lighting device 1 via the input / output circuit 9b. Thus, only the two lighting fixtures 1R1 and 1R2 on the front surface of the in-car lighting device 1 are turned on. In this way, only the two lighting fixtures 1R1 and 1R2 on the front surface of the lighting fixtures 1R1 to 1R4 are thinned and turned on. Thereby, when the number of users in the car is small, for example, when the number of users is one or two, the power consumption of the car lighting device 1 can be reduced.

  In step S16, when the number of users in the car increases and a load signal R3 indicating that the load detected by the load detector 6 shown in FIG. 2 is equal to or greater than a preset load is sent to the illumination control circuit 9a. The process proceeds to step S18 in FIG. In this step S18, since the number of users in the car is large, all the lighting fixtures 1R1 to 1R4 of the car lighting device 1 are turned on. Thereafter, when the process proceeds from step S17 or step S18 to step S19, the car is landed on the response floor and the door is opened, and then in step S20, all the lighting fixtures 1R1 to 1R4 are turned off.

An example of the illumination control operation shown in FIG. 5 will be described more specifically with reference to FIG.
FIG. 6 (A) shows the operating state of the elevator, FIG. 6 (B) shows the lighting and extinguishing operation of the car interior lighting device 1 in the embodiment of the present invention, and FIG. 6 (C) shows the conventional state. The lighting and extinguishing operation | movement in an illuminating device is shown.

  In the operation state of the elevator shown in FIG. 6 (A), the elevator response starts at time P1, the car moves to the third floor, and at time P2, the car reaches the third floor and the door opens. At time P3 when the car moves, the car moves from the third floor to the fifth floor and reaches the fifth floor. Further, the car moves from the fifth floor, and at time P4, the car reaches the seventh floor. At time P7, the car is landed on the reference floor.

  In the embodiment of the present invention shown in FIG. 6B, all lighting fixtures 1R1 to 1R4 of the in-car lighting device 1 are turned off at time P1, but all lighting fixtures at time P3 slightly before time P2. 1R1 to 1R4 are turned on once. However, at time P4 slightly after time P2, since it is determined that there are few users in the car, only the two front lighting fixtures 1R1 and 1R2 are turned on, and the two rear lighting fixtures 1R3. , 1R4 is turned off.

  At time P5 just before time P3, all the lighting fixtures 1R1 to 1R4 are turned on, and on the fifth floor, since there are three or more passengers in the car, all the lighting fixtures 1R1 to 1R4 are turned on to the home country P6. It remains. At time P6, since all the users in the car got off on the seventh floor, all the lighting fixtures 1R1 to 1R4 are turned off.

  On the other hand, in the lighting device of the conventional example shown in FIG. 6 (C), when it is lit at time P1, the lighting is continued as it is, and after time P7 when the car returns to the reference floor, time P8 is delayed. Will finally be turned off.

  As can be seen by comparing FIG. 6 (B) and FIG. 6 (C), the in-car lighting device 1 of the embodiment of the present invention greatly increases the lighting start time and the lighting start time compared to the conventional lighting fixture. The power consumption of the lighting device can be greatly reduced.

  When the user presses the handicapped person call button 5c shown in FIG. 2 and the call signal R2 is supplied to the lighting control circuit 9a, the lighting control circuit 9a controls the relay contacts of the lighting fixtures 1R1 to 1R4 when the door is opened and closed. As a result of the circuit being changed, a larger amount of current is allowed to flow than usual, so that the brightness of the light source 30 of the in-car illumination device 1 can be temporarily increased to increase the amount of light, so that the inside of the car can be illuminated brighter. As a result, when special attention is required, such as when a user such as a disabled person answers a call to a disabled person, the inside of the car can be brighter than usual, and the user can get on and off the car safely. it can.

  In the embodiment of the present invention, a light source 30 which is an example of a semiconductor element is used as a light emitting element of each of the lighting fixtures 1R1 to 1R4 of the in-car lighting device 1, which is turned on and off as compared with an incandescent lamp and a fluorescent lamp. The car lighting device 1 can be frequently switched to a standby state to reduce power consumption because there is little consumption due to and there is no particular limitation on the number of times of switching between lighting and extinguishing operations. Further, since the rise time when the light source 30 is turned on and the fall time when the light source 30 is turned off are shorter than the rise time and the fall time when the incandescent lamp or the fluorescent lamp is turned on, the flickering may occur with respect to the lighting device. There is no need to devise prevention or extra modifications.

  Each of the lighting fixtures 1R1 to 1R4 of the in-car lighting device 1 uses a light source 30 of a semiconductor element that rises quickly when it is turned on, and call signals R1 and R2 that notify that the lighting control circuit 9a uses the elevator. When it is recognized that there is no user in the car based on R4 and the call signal R4 from the load detector 6, each lighting fixture 1R of the car lighting device 1 is turned off and switched to standby operation. Can do. For this reason, power consumption can be reduced and the energy saving effect is high.

  In addition, even when each of the lighting fixtures 1R1 to 1R4 is turned on again, the light source 30 of the semiconductor element having a fast rise reaction time is used, so that the work of adjusting the door opening time is unnecessary, and the troublesomeness can be eliminated. When the number of users is small, the lighting fixtures 1R1 to 1R4 can be expected to further save energy by switching from all lighting to thinning lighting.

  FIG. 7 shows an example of a relay sequence of the car call detection circuit in the embodiment of the present invention.

  In the relay sequence circuit shown in FIG. 7, for example, hall call relay contact 2F-DN (downward button 5bd on the second floor hall call button 5b), hall call relay contact 2F-UP (hall call button 5b on the second floor hall) 1st floor car call relay contact 7, call relay 2FUP76, call relay 2FDN77, 2nd floor call relay contact 2FUP78, call relay contact 1K79, and load detector 6 are electrically connected. Yes. The call relay contact 2FUP78, the call relay contact 1K79, and the load detector 6 are electrically connected to the storage / determination circuit 50 of the illumination control circuit 9a. In step S3 shown in FIG. 3, the storage / determination circuit 50 determines that the doors DR1 and DR2 are completely closed based on the open / close signal R6 shown in FIG. In step S3, the lighting control circuit 9a starts a timer count. In step S3-1, the lighting fixtures 1R1 to 1R1 are used in step S4 at an earlier time point than in the case where a conventional incandescent lamp or fluorescent lamp is used. 1R4 can be turned off.

  FIG. 8 shows an example of a relay sequence of the illumination control circuit 9a in the embodiment of the present invention. In FIG. 8, the car interior lighting device 1, the load detector 6, and the lighting control circuit 9a are electrically connected.

  The load detector 6 is connected to the storage / determination circuit 50 of the illumination control circuit 9a, and the four lighting fixtures 1R1 to 1R4 of the in-car lighting device 1 are connected to the storage / determination circuit 50. The lighting switch 10, the elevator operation switch 72, and the lighting control relay contact 70 are connected to the lighting relay 71, and an on / off signal R <b> 5 from the lighting relay 71 is supplied to the storage / determination circuit 50.

  The lighting control relay contact 70 is opened in step S4 of FIG. 3 to turn off the lighting relay 71 and turn off the lighting fixtures 1R1 to 1R4. In step S6, the lighting control relay contact 70 is turned on and the lighting relay 71 is turned on to turn on the lighting fixtures 1R1 to 1R4. To do. The lighting control relay contact 70 is opened in step S13 in FIG. 5 to turn off the lighting relay 71 and turn off the lighting fixtures 1R1 to 1R4. In step S14, the lighting control relay contact 70 is turned on and the lighting relay 71 is turned on to turn on the lighting fixtures 1R1 to 1R4. To do. The lighting control relay contact 70 is closed in steps S17 and S18 of FIG. 5 to turn on the lighting relay 71 and light the lighting fixtures 1R1 to 1R4.

  In FIG. 8, in step S16 of FIG. 5, the car call registration number is smaller than the preset registration number, and the load of the user on the car floor detected by the load detector 6 is greater than the preset load. The load signal R3 indicating that the number is too small is sent to the storage / determination circuit 50 of the lighting control circuit 9a. The storage / determination circuit 50 has a small number of users in the car, for example, one or two users. If it is determined, the process proceeds to step S17. In step S17, the memory / determination circuit 50 supplies the power output R7 only to each of the two lighting fixtures 1R1 and 1R2 on the front of the lighting fixtures 1R1 to 1R4. Only one lighting fixture 1R1, 1R2 can be lit. In this way, only the two lighting fixtures 1R1 and 1R2 on the front surface of the lighting fixtures 1R1 to 1R4 are thinned and turned on. Thereby, reduction of the power consumption of the in-car illuminating device 1 can be aimed at.

  Further, in step S16, a load signal R3 indicating that the number of users on the car increases and the load detected by the load detector 6 shown in FIG. 2 is equal to or greater than a preset load (for example, 25% or more). When sent to the memory / determination circuit 50, since the number of users in the car is large in step S18, all the lighting fixtures 1R1 to 1R4 of the car lighting device 1 can be turned on.

  In addition, when the value of the load signal R3 is small and the memory / determination circuit 50 determines that the number of users in the car is, for example, one, only the right lighting device 1R1 on the front side can be turned on. Thereby, when the number of users is one, even if only the lighting fixture 1R1 is lit, the car operation panel 3 in the car can be sufficiently recognized, and the power consumption of the car lighting device 1 is reduced. Can be achieved.

  Incidentally, as shown in FIG. 8, each of the lighting fixtures 1R1 to 1R4 of the car interior lighting device 1 includes a light source 30 and a light amount adjusting unit 120 that adjusts the light amount generated by the light source 30. The light amount adjusting unit 120 includes a first series circuit of a relay switch 30S and a resistor 30R, and a second series circuit of a relay switch 30D for switching the light amount and another resistor 30H. The two series circuit is connected to the light source 30. The relay switch 30S and the relay switch 30D are interlocked so that on / off is reversed.

  When the relay switch 30S is turned on, the current passes through the resistor 30R and the light source 30, so that the light source 30 is lit with a normal light amount (luminance). On the other hand, when the switch 30D is turned on instead of the relay switch 30S, a larger amount of current passes through the resistor 30H and the light source 30, so that the light source 30 can be lit with a larger amount of light (luminance) than usual.

  Thereby, when the user presses the handicapped person call button 5c shown in FIG. 2 and the call signal R2 is supplied to the lighting control circuit 9a, the lighting control circuit 9a switches the relay switches of the lighting fixtures 1R1 to 1R4 when the door is opened and closed. The circuit is changed by the control so that a larger amount of current flows than usual, so that the brightness of the light source 30 of the in-car lighting device 1 can be temporarily increased to increase the amount of light so that the inside of the car can be illuminated brighter. Accordingly, since the inside of the car becomes brighter, the disabled can get on and off the car more safely.

  In the embodiment of the present invention, the user is placed in the elevator car, and after a certain period of time has passed without a call registration from the user, the car is turned off so that the user can enter the car. Power consumption during standby can be reduced. Using a light source of a semiconductor element that has a fast rise (reaction) time, and when there are no users in the elevator car, the light source can be turned off quickly to reduce power consumption. Even in the case of relighting, there is no need to adjust the door opening time until the lighting state is stabilized by quickly relighting the light source of the semiconductor element.

  The plurality of lighting fixtures are disposed on the ceiling of the car, and the light sources of the semiconductor elements of the plurality of lighting fixtures are turned off and on independently by the lighting control means. Thereby, since the lighting number of a lighting fixture can be changed according to the driving | running state of a car and the number of users in a car, power consumption can be reduced.

  The lighting control circuit 9a, which is a lighting control means, turns on the light sources 30 of the semiconductor elements 1R1 to 1R4 in accordance with the detected car call signal R4 and the hall call signals R1 and R2. Accordingly, the light source 30 that is the light source can be turned on and off depending on the situation. For example, when the car moves in response to a hall call (stop call) or when the car is returned to the reference floor. In addition, or when the number of users in the car is small, the lighting fixtures can be turned off or thinned out, and the power consumption can be reduced.

  The floor of the car has a load detector that detects the load of the user on the car, and the lighting control means supplies the light sources of the semiconductor elements of the plurality of lighting fixtures according to the load signal of the load detector. Select and light up. This makes it possible to change the number of lighting fixtures depending on the number of users in the car.For example, when the car moves in response to a hall call (stop call), the car moves to the reference floor. When returning to home or when the number of users in the car is small, the lighting fixtures can be turned off or thinned out, reducing the power consumption.

  The luminaire includes a light amount adjustment unit capable of adjusting the light amount of the light source of the semiconductor element. Thus, for example, when the user is disabled, for example, when opening and closing the door, special attention is required, such as when the door is opened / closed. The user can get on and off safely.

  The present invention is not limited to the above embodiment. For example, a semiconductor element that is a light-emitting light source used in a car interior lighting device is not limited to a light source, and may be other types of elements. The in-car lighting device 1 includes, for example, four lighting fixtures 1R1 to 1R4, but may include two, three, or five or more lighting fixtures.

  Furthermore, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiments of the present invention. For example, you may delete some components from all the components shown by embodiment of this invention. Furthermore, you may combine the component covering different embodiment suitably.
