<< Embodiments >>
Hereinafter, five embodiments of the autonomous mobile lighting device according to the present embodiment will be described in detail with reference to the drawings. In all the drawings for explaining the embodiments, the same constituent elements are given the same reference numerals, and the duplicate description will be omitted as appropriate.

<< First Embodiment >>
As shown in FIG. 1, the autonomous mobile lighting device 10 includes an optical sensor 1, a photoelectric conversion unit 2, a storage battery 3, a light emitting unit 4, a moving unit 5, a control unit 6, and an external power supply connection unit 7. And an operation unit 8 and a GPS (Global Positioning System) information receiving unit 9.

The optical sensor 1 detects the illuminance of external light.
The photoelectric conversion unit 2 is means for converting light energy into electrical energy, and is realized by, for example, a photoelectric conversion element.
The storage battery 3 charges the electrical energy converted by the photoelectric conversion unit 2.

The light emitting unit 4 is a unit that emits light by electric energy charged in the storage battery 3 or electric energy supplied from an external power source (not shown) connected to the external power source connection unit 7, and is realized by, for example, a light emitting element. Is done.
The moving means 5 is a means for moving the autonomous mobile lighting device 10 and is realized by, for example, a tire and a drive mechanism.

The control unit 6 is means for acquiring information from other configurations (such as the optical sensor 1), performing various calculations, and controlling other configurations (such as the light emitting unit 4). Realized by Processing Unit).
The external power source connection unit 7 is a connection unit for connecting the autonomous mobile lighting device 10 to an external power source (not shown).

The operation unit 8 is an operation means for the user to set timing related to the operation of the autonomous mobile lighting device 10 or to perform manual operation.
The GPS information receiving unit 9 is means for receiving GPS information (information carried on electromagnetic waves) from a GPS satellite (not shown). The control unit 6 can calculate the position of the autonomous mobile lighting device 10 using the GPS information.

  Next, the basic operation of the autonomous mobile lighting device 10 shown in FIG. 1 will be described. When the optical sensor 1 detects an illuminance that is equal to or higher than the first threshold (for example, illuminance during the day), the control unit 6 controls the moving means 5 and is the most movable range within which the autonomous mobile lighting device 10 can be moved. Move to a place with high illuminance and stop. And the control part 6 makes the storage battery 3 charge the electrical energy generated by the photoelectric conversion part 2 in the place. As a result, the photoelectric conversion unit 2 can perform solar power generation in the brightest place, so that the power generation efficiency can be maximized. As the photoelectric conversion unit 2, for example, a solar cell, in particular, an organic solar cell (OPV: Organic Photo Voltaic) may be used.

  In addition, when the optical sensor 1 detects an illuminance less than the second threshold (for example, an illuminance from evening to night), the control unit 6 controls the moving unit 5 to move the autonomous mobile lighting device 10 It is moved to a place where the illuminance is lowest or a predetermined place and stopped. And the control part 6 makes the light emission part 4 light-emit with the electrical energy charged in the storage battery 3 in the place. Thereby, since the autonomous mobile illumination device 10 can emit light by the light emitting unit 4 in the darkest place or a predetermined place at night, an effective illumination can be realized. For example, an organic EL (OEL) element or an LED may be used as the light emitting unit 4.

  Here, the threshold value relating to the illuminance detected by the optical sensor 1 may be arbitrarily adjusted according to the environment or situation in which the autonomous mobile illumination device 10 is used, the user's preference, or the like. As an example of a standard for the illuminance threshold, the illuminance threshold (first threshold) when starting photovoltaic power generation and charging at the photoelectric conversion unit 2 at an illuminance of a predetermined value or higher is, for example, 300 Lux, preferably Is 500 Lux, particularly preferably 1000 Lux. In addition, the illuminance threshold value (second threshold value) when light emission is started in the light emitting unit 4 with illuminance less than a predetermined value is, for example, 100 Lux, preferably 50 Lux, and particularly preferably 10 Lux. In the above example, the first threshold value and the second threshold value are different from each other, but both threshold values may be the same.

  When the illuminance detected by the optical sensor 1 is a value between the first threshold value and the second threshold value when the first threshold value and the second threshold value are different, for example, the autonomous mobile illumination device 10 May be set so that nothing operates, but is not limited to this.

  In addition, when the remaining amount of electric energy charged in the storage battery 3 is equal to or less than a predetermined value (for example, 20% or less of the total capacity), the control unit 6 controls the moving unit 5 to activate the autonomous mobile lighting device 10. Move to an external power source (not shown). Then, the external power supply connection unit 7 is connected to an external power supply (not shown) for charging. As a result, even when the daytime is rainy or cloudy and the storage battery 3 is not sufficiently charged by the photoelectric conversion unit 2, the storage battery 3 is charged by an external power source (not shown). Can perform desired light emission and illumination at night. As a method of controlling the moving means 5 to move to a place where an external power source (not shown) exists, the autonomous mobile lighting device 10 includes a contact sensor, and the wall contacts the wall while the contact sensor contacts the wall. There is a method of guiding the autonomous mobile lighting device 10 to a place where an external power source (not shown) installed along the road exists.

  Further, when the remaining amount of the electric energy charged in the storage battery 3 is reduced to a predetermined value or less (for example, 20% or less of the total capacity) during the light emission of the light emitting unit 4, the control unit 6 Electrical energy can be acquired by connecting 7 to an external power source (not shown), and the light emission unit 4 can continue to emit light. Thereby, even when the capacity of the storage battery 3 is insufficient, the light emitting unit 4 can perform light emission and illumination at a desired place.

  Note that the intensity of illumination may be different according to the level of illuminance detected by the optical sensor 1. For example, the lower the illuminance, the stronger the illumination. Or you may set the intensity | strength of illumination according to every room, such as a study, a kitchen, and a washroom, beforehand.

  Furthermore, if the timing regarding the operation of the autonomous mobile lighting device 10 is set using the operation unit 8, the control unit 6 can start control based on the set timing. For example, the control unit 6 uses the illuminance detected by the optical sensor 1 and the timing set in the operation unit 8 to determine whether the AND condition or the OR condition is satisfied, so that the autonomous mobile lighting device 10 Movement control, charge control to the storage battery 3 by the photoelectric conversion unit 2, light emission control by the light emitting unit 4, and the like can be performed.

  In addition, the control unit 6 gives priority to the illuminance detected by the optical sensor 1 and controls the movement of the autonomous mobile lighting device 10, the charging control to the storage battery 3 by the photoelectric conversion unit 2, and the light emission based on the set timing. Light emission control by the unit 4 can be performed. Specifically, for example, it can be set to move to a window in a room at 6 o'clock in the morning to start charging, and to move to the center of a room at 6 o'clock in the evening to start light emission.

  In addition, the control unit 6 can perform various controls by specifying the moving path, the power generation location, the illumination location, and the like of the autonomous mobile lighting device 10 based on the GPS information from the GPS information receiving unit 9.

  Next, the configuration of the autonomous mobile lighting device 10 will be described. As shown in FIG. 2A, the autonomously moving illumination device 10a (10) is formed in a substantially cylindrical shape, and a photoelectric conversion unit 2 made of, for example, an organic solar cell (OPV) is mounted on the top surface. A plurality of (three in FIG. 2) photosensors 1 are arranged at substantially equal intervals around the circumference. In addition, a plurality of light emitting units 4 made of, for example, organic EL (OEL) are arranged on the substantially cylindrical side surface at substantially equal intervals. Further, as shown in FIG. 2B, a plurality (three in FIG. 2) of moving means 5 made of, for example, rubber rollers are attached to the substantially cylindrical bottom surface. These moving means 5 can change a moving direction freely like a caster of a base.

  In addition, since the storage battery 3, the control part 6, the operation part 8, the GPS information receiving part 9, etc. which are other components are mounted in the autonomous mobile lighting device 10a, they are not displayed in FIG. Moreover, although the rubber roller is shown in FIG. 2A as the moving means 5, it may be a rigid wheel for moving on the ground surface, a walking foot mechanism, a caterpillar, or the like.

  In addition, if there are a plurality of optical sensors 1 and each is arranged so that the illuminance detected by the direction of the light source is different from each other, the control unit 6 can adjust the illuminance detected by the plurality of optical sensors 1. Based on this, the direction of the light source can be specified, and movement control by the moving means 5 can be performed. In that case, it is necessary to adjust the direction of each of the optical sensors 1 so that the amount of light received by each of the optical sensors 1 is different for, for example, sunlight from an oblique direction.

  Moreover, the incident angle of the external light can be detected together with the illuminance of the external light by using the plurality of optical sensors 1. Therefore, the control unit 6 can control the lighting surface of the photoelectric conversion unit 2 to an optimum inclination angle based on the illuminance detected by the optical sensor 1 and the information on the incident angle. That is, as shown in FIG. 3, based on the information on the illuminance and incident angle of external light detected by a plurality of optical sensors 1, the control unit 6 uses a photoelectric conversion unit with the maximum illuminance of external light (sunlight). The inclination angle changing means 20 is controlled so as to be incident on 2, and the inclination angle of the photoelectric conversion unit 2 with respect to the horizontal plane can be set to an optimum value.

  If the incident angle of external light is not detected, control is performed such that the lighting surface of the photoelectric conversion unit 2 is moved little by little in various directions and the direction of the lighting surface of the photoelectric conversion unit 2 having higher power generation efficiency is searched. Also good. In that case, you may make it install each optical sensor 1 in the lighting surface of the photoelectric conversion part 2 so that the photoelectric conversion part 2 may not block the external light to the optical sensor 1. FIG.

  Next, another configuration example of the autonomous mobile lighting device 10 will be described. As shown in FIG. 4, the autonomously moving illumination device 10 b (10) has a substantially conical shape, the photoelectric conversion unit 2 is disposed on a part of the side surface, and the light emitting unit 4 is disposed on the other part of the side surface. . And the optical sensor 1 is arrange | positioned at the top part, and the rubber roller is arrange | positioned as the moving means 5 at the bottom face. As a result, the autonomous mobile lighting device 10b shown in FIG. 4 appropriately moves on the ground, performs solar power generation and charging with the photoelectric conversion unit 2 facing sunlight during the daytime, and desires the light emitting unit 4 at night. Light emission / irradiation can be performed toward the irradiation surface.

  Next, another configuration example of the autonomous mobile lighting device 10 will be described. As shown in FIG. 5, the autonomously moving illumination device 10 c (10) has a substantially spindle shape, the photoelectric conversion unit 2 is disposed on a part of the side surface, and the light emitting unit 4 is disposed on the other part of the side surface. . And the optical sensor 1 is arrange | positioned at the front-end | tip part of the right side of FIG. 5, and the propeller as the moving means 5a (5) is arrange | positioned at the front-end | tip part of the left side of FIG. Accordingly, the autonomously moving illumination device 10c shown in FIG. 5 moves appropriately while floating in the air, performs solar power generation and charging with the photoelectric conversion unit 2 facing sunlight during the daytime, and the light emitting unit 4 at nighttime. Can be emitted and irradiated toward a desired irradiation surface.

  The photoelectric conversion unit 2 and the light emitting unit 4 closed in a spindle shape are filled with a gas (such as helium) that is lighter than air, so that even when the propeller serving as the moving unit 5a is stopped, it moves autonomously. The mold lighting device 10c can float in the air. Further, the movement range may be limited by connecting the autonomously moving illumination device 10c with a rope or the like.

  Next, the flow of operation of the autonomous mobile lighting device 10 will be described. As shown in FIG. 6, this operation includes a daytime mode and a nighttime mode. First, in the daytime mode, when the main power is turned on by the operation of the operation unit 8 by the user (step S1), an illuminance check is performed by the optical sensor 1 and the control unit 6 (step S2). Here, when it is daytime and the illuminance is greater than or equal to a predetermined value (first threshold) (“high” in step S2), the charge amount of the storage battery 3 is checked by the control unit 6 (step S3). 3 is insufficient (“insufficient” in step S3), the control unit 6 controls the moving means 5 so that the autonomous mobile lighting device 10 moves to a bright place (step S4). .

  After step S4, the control unit 6 performs solar power generation by the photoelectric conversion unit 2, performs light reception charging to the storage battery 3 (step S5), and returns to step S2. In this way, steps S2 to S5 are repeated while constantly performing the illuminance check, and charging of the storage battery 3 by photovoltaic power generation is continued by the photoelectric conversion unit 2 during the daytime. If the charge amount of the storage battery 3 is sufficient in step S3 (“sufficient” in step S3), the charging mode by the photoelectric conversion unit 2 is temporarily stopped (step S6), the process returns to step S2, and the illuminance check is performed. Continue.

  Next, in the night mode, when the main power is turned on by the user operating the operation unit 8 (step S1) (or continuing from the daytime mode), the light sensor 1 and the control unit 6 perform illuminance check. (Step S2). Here, at night, when the illuminance is less than the predetermined value (second threshold) (“low” in step S2), the control unit 6 checks the charge amount of the storage battery 3 (step S13), and the storage battery 3 When the charging amount is sufficient (“sufficient” in step S13), the control unit 6 controls the moving means 5, so that the autonomous mobile lighting device 10 moves to a dark place or a predetermined place (step S14). ), The light emitting unit 4 emits light by the electric energy from the storage battery 3 (step S15), and the process returns to step S2. In this way, steps S2 and S13 to S15 are repeated while constantly performing an illuminance check, and illumination by the light emitting unit 4 is continued during the night.

  In addition, when the charged amount of the storage battery is insufficient in Step S13 (“insufficient”), it is checked whether or not the external power source is available by the control unit 6 (Step S16), and the external power source is available. If so ("possible" in step S16), the control unit 6 controls the moving means 5, so that the autonomous mobile lighting device 10 moves to a place where there is an external power source and performs electrical connection (step S17). ) Illumination is performed by causing the light emitting unit 4 to emit light with electric energy obtained from the external power source (step S15), and the process returns to step S2. On the other hand, if the external power source cannot be used in step S16 (“impossible” in step S16), the control unit 6 ends the process.

<< Second Embodiment >>
Next, the configuration of the autonomous mobile lighting device 10d (10) according to the second embodiment will be described. The autonomous mobile lighting device 10d shown in FIG. 7 is different from the autonomous mobile lighting device 10 shown in FIG. 1 in that an external information receiving unit 11 that receives external information related to illuminance and a human sensor 12 that detects surrounding people. And the cleaning means 13 which cleans the ground is added. Of course, these elements do not have to be added all at once, and each of them may be added alone.

  The autonomous mobile lighting device 10d includes the external information receiving unit 11, so that the control unit 6 moves the moving unit 5 based on external information such as weather information and sunshine forecast information received by the external information receiving unit 11. Can be controlled. That is, the control unit 6 can control the moving unit 5 so that, for example, the autonomously moving illumination device 10d does not go outdoors during rainy weather.

  In addition, since the autonomously moving illumination device 10d includes the human sensor 12, the control unit 6 can perform the presence / absence of an illumination operation by the light emitting unit 4 and adjustment of illuminance based on the detection information of the human sensor 12. it can. That is, for example, the control unit 6 does not perform the illumination operation by the light emitting unit 4 when the human sensor 12 does not detect a person around, and emits light when the human sensor 12 detects a person around. By performing control so that the illumination operation by the unit 4 is performed, both necessary illumination operation and power saving can be achieved. Further, by using the human sensor 12, the autonomously moving illumination device 10d can be moved in accordance with the movement of the person while performing the illumination operation by the light emitting unit 4.

  Furthermore, since the autonomously moving illumination device 10d includes the cleaning unit 13, when the autonomously movable illumination device 10d moves, the cleaning unit 13 can clean the ground in the movement path, and the effect of two birds with one stone can be achieved. it can.

<< Third Embodiment >>
Next, a third embodiment of the present invention will be described. As shown in FIG. 8, in the third embodiment, a plurality of autonomously moving illumination devices 10d (two in FIG. 8) are used and are connected to each other by mutual communication means 14 (for example, mutual communication interfaces). Yes. In this way, if the autonomous mobile lighting devices 10d communicate with each other, the lighting environment can be adjusted in cooperation with each other.

  Specifically, for example, a plurality of autonomous mobile lighting devices 10d gather at the same place to perform illumination, thereby providing a brighter environment, or each of the multiple autonomous mobile lighting devices 10d in a wide range. It is possible to provide an illumination environment that suits each user's preference, such as separately illuminating indoor rooms individually.
