Reference numeral 1 indicates a room such as a hospital, an elderly facility, or a general home, 2 indicates an outdoor space such as a corridor, and 3 indicates an entrance to the room 1.

  Reference numeral 4 denotes a bed installed in the room 1, and the bed 4 is provided with a bed detection means 5. That is, in this embodiment, the bed 4 supports the leg 6 by placing it on a load sensor 7 such as a load cell and detects the load of the bed 4 from the output of these load sensors 7 every moment. 8 is configured as a control device 9. When a user is present on the floor of the bed 4, the load detected by the load detection means 8 via the load sensor 7 is a value obtained by adding the weight of the user to the weight of the bed 4 itself. When the user gets off the floor of the bed 4, the weight of the user is reduced. Therefore, the load is changed so that the user is on the floor, i.e., the user is on the floor or not, It is possible to detect whether the user is not in bed. That is, the load sensor 7 and the load detection unit 8 constitute the above-described bed detection unit 5.

First, in step S1, the presence / absence of an operation for changing the illumination control mode is determined. Note that there are two illumination control modes, an automatic illumination control mode according to the present invention and a normal manual operation illumination control mode. The automatic illumination control mode is set, for example, at bedtime.

  If there is no operation for changing the illumination control mode in step S1, the process proceeds to step S3 to determine whether or not the automatic illumination control mode is set. If the automatic illumination control mode is not set, the process returns to step S1 to monitor the change of the illumination control mode. On the other hand, when the automatic lighting control mode is set, the process proceeds to step S4, and the presence detection means 5 determines whether the user is in the presence of the floor or not.

  In the case of being in the floor, the process goes to step S5 and continues to be turned off, so that the user's sleep is not hindered.

  On the other hand, when it becomes a non-bed state, it transfers to step S6 and turns on a lighting fixture, and the 1st lighting fixture 10 and the 2nd lighting fixture 11 in this case. Hospital rooms and the like are dimly lit even at night, so there is no problem in the operation until the user gets off the floor. When the user gets off, the first lighting device 10 and the second lighting device 11 are turned on. It is possible to safely walk indoors and walk outdoors.

  When the user gets on the floor again in this way, the process proceeds from step S4 to step S5, the first lighting apparatus 10 and the second lighting apparatus 11 are turned off, and thus the sleep environment is automatically adjusted. be able to.

  That is, in the second embodiment, the pressure sensor 17 is provided at the edge of the floor portion, and the pressure detection that detects the pressure at the edge of the floor portion by the pressure sensor 17 is performed in the control device 9 every moment. The means 18 is configured in the control device 9. When the weight of the user is applied to the edge of the floor, pressure is applied to the pressure-sensitive sensor 17, so whether or not the user is on the edge of the floor due to the change in pressure, that is, whether the user is in the end sitting position or not. Can be detected. That is, the pressure sensor 17, the pressure detection unit 18, and the control unit 13 constitute the above-described end sitting position detection unit 16.

In the above configuration, an example of the control operation of the illumination control mechanism of the present invention will be described with reference to the flowchart of FIG.
First, in step S11, it is determined whether or not there is an operation for changing the illumination control mode.

  If there is no operation for changing the illumination control mode in step S11, the process proceeds to step S13 to determine whether or not the automatic illumination control mode is set. If the automatic illumination control mode is not set, the process returns to step S11 to monitor the change of the illumination control mode. On the other hand, when the automatic illumination control mode is set, the process proceeds to step S14, and the end sitting position detection unit 16 determines whether or not the end sitting position state is set.

  When it is in the end-sitting position, the process proceeds to step S15 to turn on the lighting fixture, in this case, the first lighting fixture 10 and the second lighting fixture 11. Therefore, it is possible to safely perform the operation until the user gets off the floor, the indoor walk after that, the outdoor walk, and the like.

  The state determined not to be in the end-sitting position in step S14 may be when the user is on the floor or when the user is away from the bed. The detection means 5 determines whether the user is in a bed or not.

  In the case of being in the floor, the process proceeds to step S17 and continues to be turned off, so that the user's sleep is not hindered.

  On the other hand, in the case of a non-floating state, the process proceeds to step S15, and as described above, by continuing lighting of the lighting fixture, in this case, the first lighting fixture 10 and the second lighting fixture 11, It is possible to safely walk indoors after walking down from the floor, walk outside the user, and the like.

  When the user gets on the floor again in this way, the process proceeds from step S16 to step S17, the first lighting device 10 and the second lighting device 11 are turned off, and thus the sleep environment is automatically adjusted. be able to.

  Similarly to the above, if the control means 13 or the lighting controller 14 is provided with an off-delay operation means in the extinguishing operation, the lighting apparatus is kept on until the user enters the sleep position after getting on the floor. It is convenient because it can.

Since other control operations are the same as those in the flow of FIG. 4, the same steps are denoted by the same reference numerals, and redundant description is omitted.

  Here, the contents of the first lighting control and the second lighting control will be described. First, as the first example, the first lighting fixture for the side lower illumination of the bed 4 in the first lighting control is described. 10 can be turned on, and the third lighting fixture 12 outside can be turned on in the second lighting control.

  In such a control, in the end-sitting position, only the lower side of the bed is illuminated, so that when multiple beds are installed in a sickroom, the sleep of other bed users is inhibited. In addition, it is convenient because the illumination of the outdoor space such as the corridor and the washroom can be automatically turned on by leaving the bed.

  As another example, the first lighting fixture 10 for lighting the lower side of the side of the bed 4 is turned on in the first lighting control, and the other lighting fixtures in the room, that is, the second lighting fixture in the second lighting control. It can be set as the structure which lights the lighting fixture 11. FIG.

  In such a control, in the end sitting position, only the lower side of the bed is illuminated, and when the second lighting fixture 11 in the room is turned on for the first time when the bed is separated from the bed, the end sitting position is entered, When returning to the floor again, the second lighting device 11 can be prevented from being turned on.

Next, FIG. 6 is explanatory drawing which shows 3rd Embodiment of the automatic illumination control mechanism in the bed of this invention, FIG. 7, FIG. 8 shows an example of the flow of the control.

  If there is no operation for changing the illumination control mode in step S21, the process proceeds to step S23 to determine whether or not the automatic illumination control mode is set. If the automatic illumination control mode is not set, the process returns to step S21 to monitor the change of the illumination control mode. On the other hand, when the automatic illumination control mode is set, the process proceeds to step S24, and it is determined whether or not there is a person in the room by the person detecting means.

  If it is determined that there is no person, the process proceeds to step S28, and the lighting fixture, in this case, the second lighting fixture 11 in the room is turned off. On the other hand, if it is determined that there is a person, the process proceeds to step S25, and the end-sitting position detection means 16 determines whether or not the end-sitting state is set.

  When the end sitting position is reached, the process proceeds to step S26, and the lighting fixture, in this case, the first lighting fixture 10 and the second lighting fixture 11 are turned on. Therefore, it is possible to safely perform the operation until the user gets off the floor, the indoor walk after that, the outdoor walk, and the like.

  The state determined not to be in the end-sitting position in step S25 may be when the user is on the floor or when the user is away from the bed. The detection means 5 determines whether the user is in a bed or not.
