Description

  The present invention relates to a phosphorescent illumination device that accumulates light emitted from a light source such as an LED, a fluorescent lamp, a discharge lamp, or a tungsten lamp as accumulated light, and radiates the accumulated accumulated light into illumination light.

Conventionally, for example, as described in Patent Document 1, a phosphorescent body (phosphorescent section) that accumulates light emitted from a lighting fixture is installed in the vicinity of the lighting fixture, and light emitted from the lighting fixture is stored in the phosphorescent body. After storing the light, it was removed from the vicinity of the luminaire and carried and illuminated by radiating the luminescence of this phosphor in a place far away from the luminaire.
Hereinafter, a conventional phosphorescent illumination device will be described with reference to the drawings.

  FIG. 7 is a cross-sectional view showing a configuration of a conventional phosphorescent illumination device.

  As shown in FIG. 7, the conventional phosphorescent illumination device 100 is configured by attaching a phosphorescent body 101 that can be attached and detached in the vicinity of a lighting fixture including a socket 102 and a light source 103 attached to the socket 102. Yes. The light source 103 is an incandescent lamp or an arc tube.

  The phosphorescent body 101 accumulates light by light emitted from the light source 103 when it is mounted in the vicinity of the lighting fixture. The phosphorescent body 101 is formed by applying a phosphorescent material on a base material made of a transparent or translucent material, and covers the light source 103 when mounted in the vicinity of the lighting fixture.

  In this embodiment, the phosphorescent body 101 is formed in a truncated cone shape from a disk-shaped bottom plate portion and a conical surface-like side wall portion. The upper end portion of the phosphorescent body 101 has a larger opening end than the bottom plate portion, and the light source 103 is inserted therein.

  Since the phosphorescent body 101 is disposed so as to cover the periphery of the light source 103, the phosphorescent material in the phosphorescent body 101 is directly excited by the light emitted from the light source 103. The phosphorescent material is, for example, a highly weatherable phosphorescent paint described in Non-Patent Document 1 is applied thinly on a transparent or semitransparent material so as to be translucent, and the light emitted from the light source 103 is reflected. A part is set to transmit the phosphorescent body 101.

  In this phosphorescent illumination device 100, when the phosphorescent body 101 is mounted in the vicinity of the luminaire, the light source 103 is put into a normal use state and emits light, whereby the surrounding illumination by this light is performed. At the same time, light storage by the light storage body 101 is performed.

At this time, a part of the light emitted from the light source 103 is consumed by excitation of the phosphorescent material in the phosphorescent body 101 and accumulated as phosphorescent light, and the remaining part is transmitted through the phosphorescent body 101 to illuminate the surroundings.
When the light source 103 is turned off, ambient light is emitted by radiating the light stored in the light storage body 101.

  Then, when the phosphorescent body 101 is detached from the vicinity of the lighting fixture, even if there is no light source 103, the phosphorescent body 101 can radiate the phosphorescent light accumulated in the phosphorescent body 101 to be used as illumination light. For this reason, the phosphorescent body 101 removed from the vicinity of the luminaire is carried and used as a non-feed-type phosphorescent illumination device.

Development of highly weather-resistant phosphorescent paint "HOTARU" Research by Yutaka Masuda and Masao Kobayashi Research on paints (Kansai Paint Co., Ltd. public relations magazine) 138 July 2002

In the conventional phosphorescent illumination device using the phosphorescent body as described above, the light emitted from the light source of the lighting fixture is stored in the phosphorescent body, and part of the light emitted from the light source of the lighting fixture is stored in the phosphorescent body. Therefore, the phosphor has to be transparent or translucent.
For this reason, in order to make a phosphorescent body transparent or translucent, the phosphorescent paint applied to the phosphorescent body must be applied thinly, so that a sufficient amount of stored light cannot be obtained, and the phosphorescent light emitted from the phosphorescent body is illuminated. There is a problem that the amount of light is insufficient for use as light.
In addition, when the phosphorescent body is removed from the lighting fixture and used as a non-feed-type phosphorescent illumination device, the phosphorescent body is composed of a disk-shaped bottom plate portion and a conical surface side wall portion, so that it is portable. It is inconvenient and further radiates phosphorescent light in all directions, so that there is a problem that the amount of illumination is remarkably insufficient in the direction where illumination is required.

  Therefore, the present invention has been proposed in view of the above-described circumstances, and an object thereof is to provide a phosphorescent illumination device that can sufficiently store the light necessary for illumination and is easy to carry.

  In the first invention of the present application, after storing incident light emitted from a light source such as sunlight, LED, fluorescent lamp, discharge lamp, tungsten lamp and the like to store the light, the stored light is emitted when the incident light is stopped.

The incident light incident from the other end side of the cylindrical portion 2 is irradiated and reflected on the reflecting portion 5 and the incident light reflecting portion 7 to be reflected, and reflected by the reflecting portion 5 and the incident light reflecting portion 7. The accumulated reflected light is accumulated in the luminous unit 3 to be stored, and when incident light incident from the other end side of the cylindrical unit 2 is stopped, the stored luminous in the luminous unit 3 is emitted to illuminate light. The phosphorescent illumination device 1 characterized by the above is provided.

  According to the present invention, after storing incident light emitted from a light source such as sunlight, an LED, a fluorescent lamp, a discharge lamp, a tungsten lamp, and the like to store light, when the incident light stops, the stored light is emitted and illuminated. In the phosphorescent illumination device 1 as light, a cylindrical portion 2 made of a transparent material such as plastic or glass, and a phosphorescent portion 3 in which a phosphorescent paint or phosphorescent paper is applied or laminated in a substantially semi-cylindrical shape inside the cylindrical portion 2; A disk-shaped fixing portion 4 made of a material such as plastic, metal, glass, or wood and fixed to one end of the cylindrical portion 2 with a screw, an adhesive, or the like, and a reflective member such as white paint or aluminum foil is provided on the fixing portion 4.

  The best mode for carrying out the present invention will be described with reference to FIGS. 1 to 6, but the present invention is not limited to such an embodiment.

Next, an example will be described.
As shown in FIGS. 1A and 1B, the phosphorescent illumination device 1 includes a cylindrical portion 2 made of a transparent material such as plastic or glass, and a phosphorescent paint or phosphorescent paper approximately halfway inside the cylindrical portion. A phosphorescent part 3 applied or bonded in a cylindrical shape, a disk-like fixing part 4 made of a material such as plastic, metal, glass, or wood and fixed to one end of the cylindrical part with a screw, an adhesive, etc., and white paint or aluminum A reflecting portion 5 in which a reflecting member such as a foil is applied or pasted on the fixing portion 4, and the cylindrical portion 2 or the fixing portion 4 is held by a screw, an adhesive, or the like, and has a joint at a substantially central position inside the cylindrical portion 2. A holding part 6 made of a material such as metal, plastic or glass, and a reflective member such as aluminum vapor deposition or aluminum foil on the surface of metal, plastic, glass or the like which is fixed to the joint part of the holding part 6 with a screw, an adhesive or the like. Applied It comprises a light reflecting portion 7, a removable protective lid portion 8 made of a transparent material such as plastic or glass, and a protective lid reflective portion 9 in which a white paint or aluminum foil is applied or bonded to the protective lid portion 8. The

The cylindrical portion 2 is formed as a hollow cylinder made of a transparent material such as plastic or glass such as acrylic or carbonate, and the outer diameter D2 is set to about 5 cm to 10 cm so as to be portable. The thickness is about 1 mm or more and less than 5 mm to give strength. The shape of the cylindrical portion 2 is a hollow cylinder, but a hollow polygonal tube may be used instead of the cylinder. For example, quadrangular, pentagonal, hexagonal, heptagonal, octagonal, etc. Of course, an ellipse may be used.
The phosphorescent unit 3 applies a white paint to the semi-cylindrical portion inside the cylindrical unit 2 in order to efficiently store the phosphor, and applies the phosphorescent paint to a thickness that allows sufficient phosphorescent storage thereon. If it does in this way, even if it permeate | transmits the phosphorescent coating material, the light which injected into the phosphorescent part 2 will be reflected by a white coating material, will be irradiated again and stored in the phosphorescent coating material. Moreover, even if the phosphorescence accumulated in the phosphorescent paint is radiated to the white paint side, it is reflected back to the phosphorescent paint side. A reflective member such as aluminum may be used instead of the white paint. In the case of using phosphorescent paper, an adhesive, white paper, phosphorescent paint, and a protective material composed of a protective material are commercially available (Komatsu Process Co., Ltd.).
The fixing part 4 has a disk-like shape with a diameter D2 made of a material such as plastic, metal, glass, or wood, and is fixed to one end (bottom part) of the cylindrical part 2 with a screw, an adhesive, or the like, and is not limited to being transparent. It may be opaque.
The reflecting portion 5 is formed on the fixed portion 4 so as to reflect light by applying or bonding a reflecting member such as white paint or aluminum foil.
The holding portion 6 is formed of a material such as metal, plastic, or glass that is held on the cylindrical portion 2 or the fixing portion 4 with a screw, an adhesive, or the like, and has a joint portion at the substantially central position inside the cylindrical portion 2, and is preferably transparent. However, when the shape is small, it may be opaque.
The incident light reflecting portion 7 is made of a material such as plastic, metal, glass or the like having a reflective member such as aluminum vapor deposition or aluminum foil on the surface, and is formed in a conical shape. It is fixed and fixed at a substantially central position inside the cylindrical portion 2. The shape may be a sphere or a polygonal sphere covered with a reflecting member in addition to a conical surface.
The protective lid 8 is formed in a disk shape having a diameter D2 so as to cover the other end (upper part) of the cylindrical portion 2 with a transparent material such as plastic or glass such as acrylic or carbonate.
The protective lid reflecting portion 9 is obtained by applying or pasting a reflective member such as a white paint or aluminum foil to the protective lid portion 8, and a region having a substantially diameter D <b> 1 at the center is blank as shown in FIG. 1.

Next, the operation will be described.
(When the protective lid 8 is attached to the phosphorescent illumination device 1)
As shown in FIG. 2, a portable light source such as a flashlight 10 is placed at the center position of the protective cover 8, and the light emission direction is directed toward the incident light reflecting portion 7 of the phosphorescent illumination device 1. When the flashlight 10 is turned on, incident light k0 is emitted and applied to the incident light reflecting portion 7. Of the incident light k0 irradiated to the incident light reflecting section 7, k1 is reflected at the position P1 of the phosphorescent section 3, k2 is reflected at the position P2, and k3 is reflected at the position P3 and accumulated as accumulated light. On the other hand, k4, k5, and k6 of the incident light k0 are reflected by the incident light reflecting portion 7 and used as the illumination light F0.
In this way, approximately half of the incident light k0 radiated from the flashlight 10 is accumulated as accumulated light in the entire phosphor storage unit 3, and the other approximately half is used as illumination light.
If the phosphorescent part 3 is deleted and a transparent cylinder is used, the incident light k0 is reflected in all directions, so that it can be used as a canter.

As shown in FIG. 3, when the flashlight 10 is turned off and the emission of the incident light incident on the phosphorescent illumination device 1 is stopped, the phosphorescent light accumulated in the phosphorescent unit 3 is emitted and used as the illumination light F1. The phosphorescent light emitted from the phosphorescent unit 3 is also reflected by the reflecting unit 5 and the protective lid reflecting unit 9 and added to the illumination light F1. When the holding part 6 is formed of a transparent material, the accumulated light passes as it is and becomes the illumination light F1.
When the flashlight 10 is radiated and illuminated to illuminate, if the flashlight 10 is detached and used only by the phosphorescent illumination device 1, portability is further improved.

  Thus, by installing the flashlight 10 in the phosphorescent illumination device 1, the incident light emitted from the flashlight 10 is irradiated with strong light because it is close to the phosphorescent unit 3, so that it is stored in the illumination. Necessary phosphorescence can be obtained in a short time. Moreover, since half of the incident light radiated | emitted from the flashlight 10 is reflected and used as illumination light also at the time of light storage, illumination can be performed simultaneously.

Next, another embodiment will be described with reference to FIGS. Since the configuration is the same except that the protective lid portion 8 is removed from FIG. 1, detailed description of each portion is omitted.
(When the protective lid 8 is removed from the phosphorescent illumination device 1)
As shown in FIGS. 4A and 4B, the operation when the protective lid 8 is removed from the phosphorescent illumination device 1 will be described with reference to FIGS.
First, when the protective cover 8 is removed from the phosphorescent illumination device 1 as shown in FIG. 5, sunlight, LED, A large amount of radiated light is emitted as incident light L0 from a light source such as a fluorescent lamp, a discharge lamp, or a tungsten lamp. Of the incident light L0, L1, L2, and L3 are reflected by the incident light reflecting portion 7, and L1 is reflected at the position P1 of the light storing portion 3, L2 is reflected at the position P2, and L3 is reflected at the position P3, respectively. Accumulated. L4, L5, and L6 are reflected by the incident light reflecting unit 7 in the opposite direction of the phosphorescent unit 3, and used as illumination light H0. Furthermore, L7 irradiated between the light storage unit 3 and the incident light reflection unit 7 in the incident light L0 is reflected by the reflection unit 5, and a part of the light is applied to the light storage unit 3 and added and stored as light storage.
In this way, approximately half of the incident light L0 emitted from the light source such as sunlight, LED, fluorescent lamp, discharge lamp, tungsten lamp, etc. and applied to the phosphorescent illumination device 1 is accumulated as phosphorous in the entire phosphorescent unit 3. The other half is used as illumination light H0.

  Next, as shown in FIG. 6, the emission from the light source of the incident light L0 emitted from the light source such as sunlight, LED, fluorescent lamp, discharge lamp, tungsten lamp, etc. and applied to the phosphorescent illumination device 1 is stopped. Then, the light storage accumulated in the light storage unit 3 is emitted and used as the illumination light H1. The phosphorescent light emitted from the phosphorescent unit 3 is also reflected by the reflecting unit 5 and added to the illumination light H1. When the holding part 6 is formed of a transparent material, the phosphorescence passes as it is.

Thus, a large amount of radiated light emitted from light sources such as sunlight, LEDs, fluorescent lamps, discharge lamps, tungsten lamps, and the like located at a position away from the side where the protective lid portion 8 of the phosphorescent illumination device 1 is removed. Can be used as the incident light L <b> 0, so that the phosphorescence is sufficiently accumulated in the phosphorescence unit 3.
Therefore, when the emitted light from the light source such as sunlight, LED, fluorescent lamp, discharge lamp, tungsten lamp is stopped, the light accumulated sufficiently in the light accumulating unit 3 can be emitted as illumination light sufficient for illumination. I can do it.
Here, the case where the protective lid portion 8 is removed has been described. However, if the protective lid reflecting portion 9 formed on the protective lid portion 8 is excluded, the same effect can be obtained even if the protective lid portion 8 is used as it is. I can do it. Furthermore, it is also possible to install the flashlight 10 on the protective lid 8 excluding the protective lid reflector 9.

As described above, even when the light source is at a close distance, it is possible to easily accumulate the light accumulation easily even if the light source is at a remote position. In addition, since the phosphorescent illumination device 1 of the present invention is configured in a portable cylindrical shape, it can easily move to a position where light is emitted from the light source, and the phosphorescent light can be stored at the moved position. Since it can be easily moved to another position after it has been sufficiently accumulated, it can be used as a portable phosphorescent illumination device that has a light source and can be easily moved to a place where light can be stored or where illumination is required.
Therefore, according to the embodiment of the present invention, it is possible to provide a phosphorescent illuminating device 1 that sufficiently stores the light necessary for illumination and is easy to carry.

In the present invention, incident light emitted from a light source is reflected by the incident light reflecting unit 7 to change the direction, irradiate the phosphor storage unit 3 and accumulate as accumulated phosphor, and then the accumulated phosphor is used as illumination light. It can be widely used for lighting devices with different directions of incident light and illumination light, and can also be applied to portable lighting devices such as outdoor lights and lanterns outdoors. It can be easily installed in settlements. It can also be used as an indoor emergency light or as a guide light when the lights are turned off during a performance at the performance hall.
In particular, since the light emission for obtaining the phosphorescence can be completed in a short time, it is obvious that the portable battery can be used effectively for a long period of time and is effective in energy saving.
