JP 2002-242487 A

By the way, when using Kantera in a tent, the combustion material used in Kantera had to be carried. In addition, there is a problem that when the burning material is lost, another illumination means must be used.

  In addition, when using a flashlight, it is conceivable to use a so-called disaster flashlight equipped with a dynamo or the like. However, a light bulb used in the flashlight requires a large amount of power and is not efficient. Here, it is conceivable to use an LED (Light Emitting Diode) element with low power consumption, but there is a problem that a sufficient light cannot be secured with a normal LED element.

  Therefore, the present invention has been made in view of such a situation, and does not require a combustion material or the like, and it is possible to ensure sufficient brightness while suppressing power consumption, and the lighting device. It aims at providing a tent provided with a lighting fixture.

  Then, in order to solve the above-mentioned subject, the irradiation instrument concerning the present invention is provided with the electric power generation part which generates electric power, and the light-emitting device which generates light based on the electric power generated by the electric power generation part, The light emitting device includes a light guide plate that guides emitted light, and the light guide plate receives the light from a side surface and emits the incident light from an output surface constituted by one main surface. It is characterized by.

  According to this configuration, light emitted based on the power generated in the power generation unit is incident from the side surface of the light guide plate. Furthermore, the light incident on the light guide plate is emitted from the emission surface. In this case, since light is irradiated through the light guide plate, a small amount of power is generated in the power generation unit.

  The tent according to the present invention includes a curtain that forms a predetermined space, a support that holds the curtain in a predetermined shape, and the irradiation tool, and the irradiation tool further includes the irradiation tool that is attached to the tent. It is characterized by comprising holding means for holding on the outer surface.

  As mentioned above, according to the irradiation instrument and tent which concern on this invention, sufficient brightness can be ensured, suppressing a power consumption, without requiring a combustion material etc.

  Hereinafter, embodiments of the irradiation apparatus and tent according to the present invention will be described in detail.

  The tent is a person inhabited temporarily in the mountains, for example, and includes a curtain 1 that forms a predetermined space, a column 2 that holds the curtain 1 in a predetermined shape, and an irradiation device 3. The curtain 1 is a partition that secures a space in which a human temporarily lives, and is, for example, a sheet-like member that is waterproofed. Moreover, the support | pillar 2 is a member for hold | maintaining the curtain 1 in a predetermined | prescribed shape, for example, forms a stainless material etc. in a cylindrical shape and is formed by combining these in a predetermined | prescribed shape.

  For example, the irradiation device 3 is fixed and charged on the roof portion of the tent during the daytime, and irradiates the inside of the tent at night. As shown in FIGS. 2 a, 2 b, and 3, such an irradiating device 3 includes a housing 5 having a light emitting device 10 therein, an irradiation region 6 formed on the surface of the housing 5, and the housing 5. The solar panel 7 formed on the surface and the switch member 8 that controls on / off of the light emitting device 10 are configured. Moreover, the irradiation instrument 3 is provided with the power removal part which is not shown in figure.

  The housing 5 is a member that integrally holds the light emitting device 10 and includes a lid member 5a and a main body member 5b. The lid member 5a is a plate-like member having a hollow at the center. The main body member 5b is formed of a box-shaped member having a hollow interior and an open top surface, and includes the light emitting device 10 therein. A solar panel 7 and a fixing member 5 are fixed to the lower surface of the main body member 5b. When the irradiation instrument 3 is used, the light emitting device 10 is disposed in the hollow portion of the main body member 5b, and the lid member 5a is disposed on the upper surface. The casing 5 is formed by covering the main body member 5b with a lid member 5a. When disposing the light emitting device 10 inside the housing 5, the light emitting device 10 is disposed inside the main body member 5b and covered with the lid member 5a so as to cover the opening of the main body member 5b. By combining the lid member 5a and the main body member 5b in this manner, the light emitted from the light emitting device 10 passes through the irradiation region 6 and is irradiated from the irradiation region 6.

  An irradiation region 6 for irradiating light emitted from the light emitting device 10 is formed on the upper surface of the housing 5. When the user irradiates the inside of the tent using the illuminating device 3, first, the illuminating device 3 is fixed to the curtain 1 in the daytime so that the solar panel 7 is exposed to sunlight. At this time, the electric power generated in the solar panel 7 is supplied to a non-illustrated power supply unit electrically connected to the solar panel 7. The power removal unit (not shown) is a member for powering the power generated in the solar panel 7. Here, it is also possible to adopt a configuration in which the electric power generated in the solar panel 7 is supplied to both the power stripping unit and the light emitting device 10. For example, when the light is emitted from the light emitting device 10, if it is possible to generate power in the solar panel 7, the power generated in the solar panel 7 is directly supplied to the light emitting device 10. At the same time, surplus power that is not necessary for the light emitting device 10 to emit light is supplied to the power supply unit. In this manner, when the light emitting device 10 emits light and the power is continuously generated in the solar power generation unit, it is not possible to generate power in the solar panel 7. It is possible to emit light. Here, for example, a secondary battery or an electrolytic double-layer capacitor can be used as the power removal unit. Further, the power removal unit may be any device as long as the power generated in the solar panel 7 can be temporarily discharged and discharged as necessary.

  Then, at night, the illuminating device 3 is removed from the curtain 1 and brought into the tent to discharge the electric power discharged to the power discharging unit to the light emitting device 10. The light emitting device 10 supplied with electric power from the voltage destroyer emits light by a method described later and irradiates the inside of the tent. As a method of fixing the solar panel 7 to the curtain 1, for example, there is a method of providing a so-called magic tape (registered trademark) material for the curtain 1 and the casing 5, respectively. Further, there are a fixing method using a bolt or the like and a fixing method using a hook or the like, but any method may be used as long as the irradiation tool 1 can be fixed to the curtain 1.

Such a light emitting device 10 includes light emitting element arrays 11a and 11b in which a plurality of light emitting elements are arranged on a predetermined substrate, a reflecting plate 12 that reflects light, a light guide plate 13, and a diffusion plate 14. ing. The light emitting element arrays 11a and 11b are members formed by arranging a plurality of LED (Light Emitting Diode) elements, for example, and are disposed on different side surfaces of the light guide plate 13, respectively. When the user uses the irradiation device 3, the switch member 8 is used to control on / off of the selected light emitting element arrays 11 a and 11 b.

  The reflecting plate 12 is a member having a predetermined optical reflectance, and is a white member formed in a plate shape, for example. The reflection plate 12 is a member for reflecting light leaking from a main surface different from the irradiation surface S of the light guide plate 13. In addition, a light guide plate 13 is disposed on the upper surface of the reflection plate 12, and light incident on the light guide plate 13 from the light emitting element arrays 11 a and 11 b is reflected by the reflection plate 12 and irradiated surface S of the light guide plate 13.

As shown in b), it is a plate-like member in which a plurality of quadrangular pyramid-shaped recesses 13a are formed on the irradiation surface S. Such a recess 13a is formed by, for example, ultrasonic processing, high frequency processing, or thermal processing. Such a recess 13a is formed in the light guide plate 13, and light is emitted from the side surface of the light guide plate by the LED element. By making the light incident, the light extraction efficiency of the light guide plate 13 can be improved. In addition, the shape of the recessed part 13a may be other pyramid shapes such as a cone, a triangular pyramid, a hexagonal pyramid, and the projection surface may be provided with a uniform convex part.

  The diffusing plate 14 is a member that uniformly diffuses the light emitted from the light guide plate 13, is formed of an optically transparent material in a plate shape, and predetermined irregularities are formed on at least one main surface. . Such a diffusion plate 14 is disposed so as to contact the irradiation surface S of the light guide plate 13.

The light irradiated from the light-emitting element array 11a and the light-emitting element array 11b is selectively incident on the light-emitting element array 11 to emit light on the irradiation surface S of the light guide plate 13. Further, the light irradiated from the irradiation surface S of the light guide plate 13 is diffused by the diffusion plate 14 and is irradiated from the irradiation region 6.

  The lid member 4 is a plate-like member formed in a rectangular shape having substantially the same size as the housing 5. One long side of the lid member 4 is rotatably supported by one long side of the housing 5, and the irradiation region is obtained by rotating one main surface of the lid member 4 so as to contact the irradiation region 6. 6 can be protected. Moreover, the solar panel 7 is arrange | positioned by the other main surface of the cover member 4, The electric power obtained in the solar panel 7 is supplied to the light emitting element arrays 11a and 11b through a power strip part.
