Description

  The present invention relates to an illumination device used for outdoor night illumination.

  Lighting devices such as street lamps, gardens and nightlights on the premises use a straight tube fluorescent lamp of several tens of watts with appropriate illuminance, a circle line, etc. as a light source, and are supplied with power from a commercial AC power source of 3 to 4 m. It illuminates from the height. Therefore, this type of illumination device has a different use from that for a roadway that illuminates from a height of 5 to 10 m using a mercury lamp or low-pressure sodium lamp having extremely high illuminance as a light source.

  In this type of lighting device, a light source is attached to the top of a 3 to 4 m post to illuminate the front obliquely from the height, and the illuminance of the light source is appropriately suppressed. Therefore, the illumination range is limited to the vicinity of the front of the post. In addition, the area around the base of the column could not be sufficiently illuminated, and the feet tended to be dark. For this reason, people with low vision, children, elderly people, people riding bicycles, etc., are difficult to see where they are away from the pillars and near the bases of the pillars. It was easy to do and sometimes fell.

For this reason, for example, Patent Document 1 proposes a technique in which an auxiliary lamp is provided at the lower part of a street light column and the lamp is illuminated by this lamp.
Japanese Patent Laid-Open No. 06-76613

  However, in Patent Document 1, an auxiliary lamp that illuminates in the 360-degree direction is used as an auxiliary lamp at the bottom of the support column. Therefore, even if the foot can be illuminated in the vicinity of the support column, it is possible to illuminate a place away from the support column. There wasn't. In addition, if the illuminance of the lamps at the upper part of the column and the auxiliary lamps at the lower part can be increased, the illumination range can be expanded, but as an illumination device such as a street light, a garden or a nightlight on the premises, too high illuminance is not preferable. The lighting range could not be easily expanded.

  Moreover, in this kind of illuminating device, the power supply which combined the solar cell and the storage battery may be used instead of a commercial alternating current power supply. In this case, it is essential to reduce power consumption, the illumination range becomes narrower, and the illuminance also decreases, making it more difficult to improve the visibility away from the column and near the base of the column.

  Therefore, the present invention has been made in view of the above-described conventional problems, and provides an illuminating device that can illuminate a place far from the vicinity of the base of the column while reducing power consumption. Objective.

  In order to solve the above-described problems, the illumination device of the present invention is provided with a support column that is erected, a main illumination unit that illuminates the vicinity of the support column, and a lower part of the support column. A sub-illumination unit having directivity, and the illumination range that cannot be illuminated by the main illumination unit is illuminated by the illumination of the sub-illumination unit having directivity.

  Moreover, in this invention, the light source of a subillumination part is LED.

  Furthermore, in this invention, the solar cell which produces | generates the electric power of a main illumination part and a subillumination part is provided.

  Moreover, in this invention, the solar cell is supported by the frame attached to the support | pillar.

  Furthermore, in the present invention, the upper part of the support is bent, the inclined head and the vertical trunk are provided on the support, and the main illumination part is divided into the inclined head and the vertical trunk.

  Further, in the present invention, at least a part of the sub-illumination part is protruded from the surface of the support column.

  Furthermore, in the present invention, the surface of the support column is a light reflecting surface in the vicinity of the sub-illumination unit.

  Moreover, in this invention, a support | pillar consists of stainless steel.

  Furthermore, in this invention, the support | pillar is made into a hollow structure and the storage battery which supplies the electric power of a main illumination part and a subillumination part is accommodated in the support | pillar.

  Moreover, in this invention, the storage battery is arrange | positioned between the main illumination part and the subillumination part.

  Furthermore, in this invention, the cross-sectional shape of the support | pillar is made into the polygon.

  According to the present invention, the main illuminating unit at the top of the column illuminates the vicinity of the column, and can illuminate, for example, the vicinity of the front of the column. In addition, the sub-illumination unit at the bottom of the column illuminates the illumination range that the main illumination unit cannot illuminate, and because it has directivity in the illumination direction, for example, it illuminates even a part far from the base of the column can do. Furthermore, since it has directivity in the illumination direction, even if the illuminance of the sub-illumination part is not particularly high, it is possible to efficiently illuminate a place far from the vicinity of the base of the column, and to improve the visibility of this illumination range. Can be secured. Therefore, the lighting device of the present invention is suitable as a street light, a garden or a nightlight on the premises, etc., and a person driving a bicycle or a car does not feel dazzled by the illumination of the sub-lighting unit. Moreover, since the illumination range of the sub-illumination unit is specified, the power consumption of the sub-illumination unit can be suppressed. Therefore, it is possible to illuminate a portion far from the vicinity of the base of the column while reducing power consumption.

  For street lights, gardens, night lights in the premises, etc., it is preferable that the height of the main illumination unit is 3 to 4 m and the height of the sub illumination unit is about 0.5 to 1.0 m.

  If there is no directivity in the illumination direction of the sub-illumination unit, it is necessary to increase the illuminance of the sub-illumination unit to illuminate the area far from the base of the column, for example, high-luminance gas sealing A light bulb or the like will be used. However, high-intensity gas-sealed light bulbs are not suitable as sub-lighting units for street lights, gardens, night lights, etc., and when used as sub-lighting units, the lighting of the sub-lighting unit is used by people who drive bicycles and cars. Feels dazzling, easily triggers an accident, and power consumption is extremely increased.

  Moreover, according to this invention, the light source of a subillumination part is LED. The LED has a full width at half maximum of, for example, about 10 degrees, has a sufficiently narrow directivity in the illumination direction, and irradiates only a specific illumination range without scattering the light. For this reason, it is possible to illuminate the road surface vividly even in the rainy or foggy night. Usually, since the illuminance per LED is low, a plurality (about 5 to 30) of LEDs arranged geometrically along a circle or polygonal line is used as the sub-illumination unit. Even in this case, the power consumption of the sub-illumination unit is only about 0.5 to 1.0 W. On the other hand, since a general light bulb does not have directivity, unless the illuminance is extremely high, it cannot serve as illumination and the power consumption becomes extremely high.

  Furthermore, according to this invention, the solar cell which produces | generates the electric power of a main illumination part and a subillumination part is provided. In this case, the power generated by the solar battery is once charged in the storage battery, and the main illumination unit and the sub-illumination unit are turned on by supplying power from the storage battery at night. Therefore, power supply from the commercial AC power supply is not required, and even if the power supply from the commercial AC power supply stops in the event of a disaster such as an earthquake, the main illumination unit and the sub-illumination unit can be turned on, and as an emergency light Can be useful.

  In addition, the main illumination unit and the sub-illumination unit are driven with a direct current, and no alternating current drive is required like a fluorescent lamp, so that it does not affect various radio devices, mobile phones, heart disease pacemakers, and the like.

  According to the present invention, since the solar cell is supported by the frame attached to the support column, the frame for supporting the solar cell itself and the frame for attaching the solar cell to the support column can be shared. Can be reduced, the structure can be simplified, the appearance can be improved, the number of parts can be reduced, and the cost can be reduced. In addition, the solar cell and the wind receiving area of the frame can be reduced to reduce their required strength, and accordingly the thickness and mass of the frame can be further reduced, and the thickness and mass of the column can also be reduced. Can do.

  Further, according to the present invention, the upper portion of the support is bent, the inclined head and the vertical trunk are provided on the support, and the main illumination unit is divided into the inclined head and the vertical trunk. As a result, the main illumination units can be distributed over a wide range, the illumination range of the main illumination unit can be set in various ways, and an excellent appearance can be obtained.

  For street lamps, night lights in gardens and premises, etc., the tilt angle of the tilted head is set to 20 to 30 degrees with respect to the horizontal, and the light of the main illumination unit is irradiated in a direction orthogonal to the tilt angle of the tilted head. Moreover, it is preferable to irradiate the light of a main illumination part in the direction of 45 degree | times diagonally downward from a vertical trunk | drum.

  Further, according to the present invention, since at least a part of the sub-illuminating unit protrudes from the surface of the support column, a slight amount of scattered light from the sub-illuminating unit is reflected by the surface of the support column and the foot is illuminated. . In this case, it is preferable to increase the light reflectivity on the surface of the support column in the vicinity of the sub-illumination unit by using the surface of the support column as a light reflection surface.

  Furthermore, because the support made of stainless steel is used, the light reflectivity of the entire surface of the support can be increased, and not only a slight amount of scattered light from the sub-illumination unit but also a slight amount from the main illumination unit. Scattered light can also be reflected from the surface of the column, and the column itself is illuminated, improving the visibility of the column and improving the appearance. In addition, the durability of the support becomes extremely high, so that painting is unnecessary, and long-term use in a fountain and a wetland is possible.

  Moreover, according to this invention, the support | pillar is made into a hollow structure and the storage battery which supplies the electric power of a main illumination part and a subillumination part is accommodated in the support | pillar. For example, the storage battery is disposed between the main illumination unit and the sub illumination unit. For this reason, a plurality of storage batteries can be accommodated in a stacked manner, and the main illumination unit and the sub-illumination unit are turned on for several days with almost no sunshine hours by a power source composed of a combination of each storage battery and a solar cell. It becomes possible. For this reason, it can serve not only as illumination but also as a guide light, a security light, an emergency light in the event of a disaster such as an earthquake.

  Furthermore, the cross-sectional shape of the column is a polygon. In this case, the pillar can be erected in a state where the pillar is not rotated by simply digging a hole in the ground, standing a pillar in the hole, pouring concrete into the hole, and hardening the concrete.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a perspective view showing Embodiment 1 of the illumination device of the present invention. 2 is a front view showing the lighting device of this embodiment, FIG. 3 is a side view showing the lighting device of this embodiment, and FIG. 4 is a plan view showing the lighting device of this embodiment as viewed from above. FIG. Furthermore, FIG. 5 is a side view showing an illumination range by the illumination device of the present embodiment.

  Hereinafter, as the lighting device of the present embodiment, a type that is fixed by a base plate and a type that is used by being embedded at a depth of 1 m in the ground without attaching a base plate will be described.

  In the illuminating device 1 of the present embodiment, the main illuminating unit 3 is provided above the support column 2, and the sub-illuminating unit 4 is provided below the support column 2. Moreover, the solar cell 5 is supported on the upper part of the support | pillar 2, and the some storage battery 6 and the charging / discharging unit 7 are arranged in the support | pillar 2 along with length. The charging / discharging unit 7 charges each storage battery 6 with the generated power of the solar battery 5 or supplies the power of each storage battery 6 to the main illumination unit 3 and the sub illumination unit 4, and the main illumination unit 3 and the sub illumination unit 4. Lights up.

  The support 2 is formed by sheet metal processing of a stainless steel plate having a thickness of 2 mm, and is a quadrangular prism-shaped hollow. The base plate 11 and each reinforcing plate 12 are made by cutting a stainless steel plate. The surface of the support | pillar 2, the base plate 11, and each reinforcement board 12 is a smooth mirror surface shape.

  The column 2 is passed through the hole 11a of the base plate 11, the base plate 11 is fixed at a position 1 m from the lower end of the column 2, and each side wall of the column 2 and the base plate 11 are connected by the four reinforcing plates 12 to the column 2 The base plate 11 is firmly attached. The support column 2, the base plate 11, and the reinforcing plates 12 are fixed to each other by welding or screwing.

  The upper part of the support column 2 is bent, and the upper part of the bent part is the inclined head part 2a, and the lower part is the vertical trunk part 2b. The inclined head 2a has a length set to about 0.6 m and an inclination angle set to 20 to 30 degrees with respect to the horizontal. The length of the vertical body 2b is set to 3.0 m for the base plate type and 4.0 m for the embedded type, and the length from the upper end of the vertical body 2b to the base plate 11 is 3 m. 0.0 m.

  The main illumination unit 3 is provided at a height of approximately 3 m (approximately 3 m above the ground) from the base plate 11, and includes six LED lamps 21 on the inclined head 2 a side and two LED lamps 22 on the vertical trunk 2 b side. Is provided. Each of the LED lamps 21 and 22 has the same structure, and as shown in FIG. 6, 18 LEDs 23 are geometrically arranged on a substrate 24 along a circle or a polygonal line, and each LED 23 and the substrate 24 are arranged. It is covered with a light scattering sphere 25, and a base 26 is fixed to the opening end 25 a of the light scattering sphere 25. The LEDs 23 are connected to each other by the wiring pattern of the substrate 24 and further connected to the base 26 via the substrate 24. The light scattering sphere 25 is, for example, a surface of a glass sphere coated with light scattering particles, and scatters light from each LED 23. Each LED 23 has a full width at half maximum of, for example, about 10 degrees, and the directivity in the illumination direction is sufficiently narrow, but those lights are scattered by the diffuser sphere 25. For this reason, the directivity as each LED lamp 21 and 22 becomes wide.

  Six circular holes 27 are provided in the lower side wall plate 2 c of the inclined head 2 a of the support column 2, and the sockets 28 are arranged and fixed behind the holes 27. Each LED lamp 21 is passed through each hole 27, and a base 26 of each LED lamp 21 is inserted and connected to each socket 28, and all LEDs 23 of each LED lamp 21 are connected to each socket 28.

  In this state, each LED lamp 21 is directed in a direction orthogonal to the inclined head 2 a inclined at 20 to 30 degrees, and is directed to the vicinity of the front of the column 2. Moreover, the directivity of each LED lamp 21 is wide. For this reason, each LED lamp 21 illuminates an illumination range A in the vicinity of the front side of the column 2 as shown in FIGS. 4 and 5. This illumination range A is about 2 m in diameter, for example.

  Further, one oval hole 31 is provided on the upper side of the front side wall plate 2d of the vertical body 2b, and two sockets 32 are arranged and fixed in the back of the hole 31. The LED lamps 22 are passed through the holes 31, and the caps 26 of the LED lamps 22 are inserted and connected to the sockets 32, and all the LEDs 23 of the LED lamps 22 are connected to the sockets 32.

  In this state, each LED lamp 22 is directed in the direction of 45 degrees obliquely downward from the vertical body portion 2b, and slightly forward of the support column 2. Moreover, the directivity of each LED lamp 22 is as wide as that of each LED 21. For this reason, each LED lamp 22 illuminates an illumination range B slightly away from the front of the column 2 as shown in FIGS. 4 and 5. This illumination range B is about 3 m in length, for example.

  Therefore, the main illumination unit 3 has a wide directivity in the illumination direction, and illuminates the illumination range A in the vicinity of the front of the column 2 shown in FIGS. 4 and 5 and the illumination range B slightly away from the front.

  The sub-illumination unit 4 includes two LED lamps 33 provided at a portion of the vertical body portion 2 b that is approximately 0.5 m (approximately 0.5 m above the ground) from the base plate 11. Each LED lamp 33 has substantially the same structure as each LED lamp 21, 22, and as shown in FIG. 7, nine LEDs 23 are geometrically arranged on a substrate 24 along a circle or polygonal line, Each LED 23 and substrate 24 are covered with a transparent sphere 29, and a base 26 is fixed to an open end 29 a of the transparent sphere 29. The LEDs 23 are connected to each other by the wiring pattern of the substrate 24 and further connected to the base 26 via the substrate 24. The transparent sphere 29 is different from the diffuse sphere 25 of the LED lamps 21 and 22, for example, is simply a transparent glass sphere, and transmits light from the LEDs 23 as it is. Therefore, the directivity of the LED lamp 33 substantially matches the directivity of each LED 23, and for example, the full width at half maximum is about 10 degrees and is sufficiently narrow, and the irradiation range is also narrowed.

  Two oblong holes 34 are provided on the lower side of the front side wall plate 2d of the vertical body 2b, and sockets 35 are arranged and fixed at the back of each hole 34, respectively. The LED lamps 33 are passed through the holes 34, and the caps 26 of the LED lamps 33 are inserted and connected to the sockets 35, and all the LEDs 23 of the LED lamps 33 are connected to the sockets 35.

  In this state, each LED lamp 33 is directed in the direction of 10 degrees obliquely downward from the vertical body portion 2 b and is directed farther forward of the column 2. Moreover, the directivity of each LED lamp 33 is narrow. For this reason, each LED lamp 33 illuminates the far front of the column 2.

  Furthermore, each LED lamp 33 slightly protrudes from each hole 34 of the front side wall plate 2d of the vertical body 2b as shown in FIG. For this reason, the slight scattered light reflected by the transparent sphere 29 of each LED lamp 33 and further reflected by the surface of the front side wall plate 2 d illuminates the vicinity of the base of the support column 2.

  Accordingly, each LED lamp 33 directly illuminates the far front of the column 2, and the scattered light of each LED lamp 33 indirectly illuminates the vicinity of the base of the column 2. That is, the sub-illumination unit 4 illuminates the illumination range C from the vicinity of the base of the support column 2 to the location far from the front as shown in FIGS. 4 and 5. The illumination range C has a maximum width of 2 m and a length of about 10 m, for example.

  Not only the LED lamps 33 but also the LED lamps 21 and 22 slightly protrude from the holes 27 and 31 of the support column 2, and the slight scattered light of the LED lamps 21 and 22 is reflected by the surface of the support column 2. Is done. Thereby, the support | pillar 2 itself is illuminated, the visibility of the support | pillar 2 improves, and an external appearance improves.

  Moreover, the illumination range C shown in FIG.4 and FIG.5 can also be directly illuminated by each LED lamp 33, shifting the inclination of each LED lamp 33 of the sub illumination part 4. FIG.

  Thus, in the illuminating device 1, the main illumination unit 3 not only illuminates the illumination range A in the vicinity of the front of the column 2 and the illumination range B slightly away from the front shown in FIG. 4 and FIG. 4 and the illumination range C from the vicinity of the base of the support 2 shown in FIG. For this reason, for example, as shown in FIG. 9, when the lighting device 1 is installed in a garden or the like, not only near the front of the column 2 of the lighting device 1, but also along the path made of the stepping stones 36 from the vicinity of the base of the column 2. Can be illuminated. Or when the illuminating device 1 is installed as a street light, it can illuminate along a street from the base vicinity of the support | pillar 2.

  Moreover, although the sub illumination part 4 is only two LED lamps 33 and the illumination intensity of each LED lamp 33 is not especially high, since it has directivity in the illumination direction of each LED lamp 33, it is near the base of the support | pillar 2 It is possible to efficiently illuminate more distant places and ensure the visibility of this illumination range. Therefore, the illuminating device 1 is suitable as a street light, a night light in a garden or a premises, etc., and a person driving a bicycle or a car does not feel the illumination of the sub-illumination unit 4 dazzling. Moreover, since the illumination range of the sub illumination unit 4 is specified, the power consumption of the sub illumination unit 4 can be suppressed. Therefore, it is possible to illuminate a portion far from the vicinity of the base of the support column 2 while reducing power consumption.

  If there is no directivity in the illumination direction of the sub-illumination unit 4, in order to illuminate a place far from the vicinity of the base of the support column 2, the illuminance of the sub-illumination unit 4 needs to be extremely high. A gas sealed bulb or the like is used. However, a high-intensity gas-sealed light bulb is not suitable as the sub-illumination unit 4 such as a street light, a garden or a nightlight on the premises, and when used as the sub-illumination unit 4, the illumination of the sub-illumination unit 4 is used for a bicycle or a car. The driver feels dazzling, easily triggers an accident, and the power consumption is extremely increased.

  Further, as described above, the LED lamps 21 and 22 of the main illumination unit 3 are each provided with 18 LEDs 23, the power consumption of the main illumination unit 3 is about several W, and the LEDs of the sub illumination unit 4 Since the lamp 33 includes each of the nine LEDs 23 and the power consumption of the sub-illumination unit 4 is about 0.5 to 1.0 W, the power consumption can be reduced. For this reason, if 2 to 6 12V long-life storage batteries are applied as each storage battery 6, the power source composed of a combination of the solar battery 5 and each storage battery 6 can be used for 5 to 10 days even if there is almost no sunshine time. The main illumination unit 3 and the sub illumination unit 4 can be turned on. For this reason, the illuminating device 1 can serve not only as illumination but also as a guide light, a security light, an emergency light in the event of a disaster such as an earthquake.

  Moreover, in each LED lamp 21, 22, 33, since several LED is geometrically arrange | positioned, the light emission itself of each LED is excellent in design, and gives a feeling of comfort to a person.

  Next, the solar cell 5, each storage battery 6, and the charge / discharge unit 7 will be described.

  The solar cell 5 is supported by a support frame 41, and the support frame 41 is rotatably supported by a shaft 42 that protrudes from the upper end of the vertical trunk portion 2 b of the column 2. FIG. 10 is a cross-sectional view showing the solar cell 5, the support frame 41, the shaft 42, and the like. The solar cell 5 has a lifetime of 20 to 30 years. For example, a single-crystal or polycrystalline solar cell is mounted and supported on the back side of a tempered glass having high sunlight transmittance, and a weather-resistant white film is bonded thereto. These are reinforced with EVA (ethylene vinyl acetate copolymer), silicone resin, or the like, and further attached with a connector box 5a. The support frame 41 is formed by sheet metal processing of stainless steel, and supports the edge of the solar cell 5 by hooking it. Further, the central portion of the support frame 41 bulges downward and becomes hollow, and the structural strength of the solar cell 5 and the support frame 41 is increased, and design changes are also provided. The connector box 5a of the solar cell 5 is accommodated here. Further, a cylindrical shaft receiver 43 is provided on the back surface of the support frame 41 so as to be inclined by 70 to 45 degrees with respect to the light receiving surface of the solar cell 5.

  The support frame 41 is rotatably supported by fitting the shaft receiver 43 on the back surface thereof to the shaft 42 at the upper end of the vertical trunk portion 2 b of the column 2. In a state of 70 degrees with respect to the light receiving surface, the light receiving surface of the solar cell 5 is inclined 20 degrees with respect to the horizontal direction. The inclination of 20 degrees is poor in the installation environment of the lighting device 1 such as a lot of light receiving obstacles caused by mountain shadows, nearby buildings, structures, etc., and direct light from the sun is almost incident on the solar cell 5 above the support column 2. When not, it is set so that more indirect light from the sky enters the solar cell 5 in place of the direct light.

  Moreover, when the installation environment of the illuminating device 1 is good and the direct light from the sun is incident on the solar cell 5 above the support column 2, the light receiving surface of the solar cell 5 is preferably inclined approximately 35 degrees with respect to the horizontal direction.

  In areas where there is a little snow in the winter season and areas where the amount of solar radiation is extremely low, such as December and throughout the year, it is better to tilt approximately 45 degrees to increase the snow sliding effect.

  Further, the support frame 41 is rotated so that the solar cell 5 is directed in the vicinity of the south direction so that the power generated by the solar cell 5 is maximized.

  A detachable back plate 2 e is screwed to the back side of the column 2. The length of the back plate 2e is substantially equal to the length of the arrangement space of each storage battery 6 and the charging / discharging unit 7. If this back plate 2e is removed, the maintenance of each storage battery 6 and the charging / discharging unit 7 is performed. Can do.

  Further, gaps are provided between the four corners of the inner wall of the support column 2 and each of the storage batteries 6 and the charge / discharge unit 7. This gap is used to discharge air that has risen in the support column 2 in the summer and gas generated from each storage battery 6 through the LED lamp holes of the support column 2 or rainwater that has entered the support column 2. And is provided for draining water from a drain hole (not shown) of the support column 2 through the condensation downward.

  Here, the generated power of the solar cell 5 is supplied to the charge / discharge unit 7. The charge / discharge unit 7 charges each storage battery 6 with the generated power of the solar battery 5. Moreover, since the power generation voltage of the solar cell 5 decreases after sunset, the charging / discharging unit 7 senses sunset when the power generation voltage of the solar cell 5 becomes a certain value or less, and mainly uses the power of each storage battery 6. Supplying to the illumination unit 3 and the sub-illumination unit 4, the main illumination unit 3 and the sub-illumination unit 4 are turned on. Further, the charging / discharging unit 7 measures the lighting time of the main lighting unit 3 and the sub lighting unit 4 and turns off the main lighting unit 3 and the sub lighting unit 4 when the set lighting time reaches a certain time. This is generally done to save power because no lighting is required at midnight. However, when the role of the lighting device 1 as a safety light or emergency light is emphasized, the main lighting unit 3 and the sub-lighting unit 4 are turned on until the remaining power of the storage battery 5 does not fall below a certain value until dawn. You may continue.

  This lighting time can be set to any time from 1 to 10 hours, and can also be set from sunset to sunrise.

  Thus, in the illuminating device 1, since the solar cell 5 is directly supported by the support frame 41, the frame for supporting the solar cell 5 itself and the frame for attaching the solar cell 5 to the support column 2 can be shared. The support frame 41 can be reduced in size, simplified in structure, improved in appearance, reduced in the number of parts, reduced in cost, and the like. Moreover, the wind receiving area of the solar cell 5 and the support frame 41 can be reduced to reduce the necessary strength thereof, and accordingly, the thickness and mass of the support frame 41 can be further reduced, and the thickness of the support column 2 can be reduced. And mass can be reduced.

  Usually, a commercially available solar cell is provided with an aluminum frame having a thickness of about 25 to 50 mm. If a double structure in which this aluminum frame is further supported by the support frame 41 of the support column 2 is adopted, the size, the structure becomes complicated, the appearance deteriorates, the number of parts increases, the cost increases, etc. Invite. Moreover, since the wind receiving area of a solar cell and a frame increases, it is necessary to increase the intensity | strength of those and the intensity | strength of a support | pillar.

  Moreover, since the power supply which consists of the combination of the solar cell 5 and each storage battery 6 is adopted, the power supply from a commercial AC power supply stops at the time of disasters, such as an earthquake, without requiring the power supply from a commercial AC power supply. In addition, the main illumination unit and the sub-illumination unit can be turned on, which can be used as an emergency light. Furthermore, the wiring work for connecting with a commercial AC power supply is not required, and the solar battery 5 can be installed in any place as long as the power generation is possible.

  Furthermore, since each storage battery 6 and the charge / discharge unit 7 are accommodated vertically between the main illumination unit 3 and the sub-illumination unit 4 in the rectangular column-shaped hollow column 2, the space in the column 2 is effectively used. be able to.

  In addition, since the sub-illumination unit 4 is disposed approximately 0.5 m above the ground, and the storage batteries 6 and the charge / discharge units 7 are disposed above the sub-illumination unit 4, even if a typhoon, heavy rain, river flooding, etc. occurs, the accuracy is The subillumination unit 4, each storage battery 6, and the charge / discharge unit 7 will not be submerged in flooding up to many below the knees.

  In addition, the main illumination unit 3 and the sub-illumination unit 4 are driven with a direct current and do not require an alternating current drive like a fluorescent lamp, which affects various wireless devices, cellular phones, heart disease pacemakers, etc. There is no.

  The base plate type is optimal when there is a possibility of relocation at a later date. It takes 2 days to dig a hole in the ground, set the anchor bolt, and then pour the concrete into it, and then install the main body after the next day the concrete has hardened.

  On the other hand, in the buried type, the installation and concrete pouring are completed in the morning, and the auxiliary stick can be removed in the evening.

  Here, the construction method of the embedment type lighting device 1 of the present embodiment will be described.

  First, the back plate 2e of the support 2 is removed, each storage battery 6 and the charge / discharge unit 7 are removed, and the weight of the lighting device 1 is reduced. In this state, since the support column 2 is formed by sheet metal processing of a stainless steel plate having a thickness of 2 mm, the weight of the illuminating device 1 is about 60 Kg and can be easily carried in manually by about two workers. And installation becomes possible.

  The thing which attaches and detaches the front plate of the support 2 is also manufactured, and the same effect has been confirmed.

  In addition, a hole with a depth of about 1 m is dug in the place where the lighting device 1 is installed, and quarry stone, chestnut stone, or the like is laid on the bottom surface of the hole. Then, the support column 2 is put in the hole, and the support column 2 is erected using an auxiliary stick or the like, and the concrete is poured into the hole so that the surface of the concrete becomes substantially the same height as the position of the base plate 11 of the support column 2. Equalize. In this state, after the concrete is hardened, the auxiliary sticks are removed.

  Furthermore, each storage battery 6 and the charging / discharging unit 7 are accommodated in the support | pillar 2, a wiring is connected, the back plate 2e is attached to the back surface of the support | pillar 2, and is screwed.

  Therefore, construction equipment such as a crane truck or excavator is not required, and the lighting device 1 can be installed by only about two workers. In addition, the lighting device 1 can be installed even in an area where there is no road or a steep slope where heavy construction equipment cannot enter. Furthermore, traffic restrictions during installation work, placement of guardmen, etc. are unnecessary.

  Moreover, since the support | pillar 2 is square pillar shape, the rotation by the typhoon or the strong wind etc. of the support | pillar 2 is prohibited by the solidified concrete. For this reason, the special structure for stopping rotation of the support | pillar 2 is not required.

  In addition, this invention is not limited to the said Example, It can deform | transform variously. For example, the number and arrangement of the LED lamps and the number and arrangement of the LEDs of the LED lamp may be appropriately changed. Moreover, you may employ | adopt the structure which can change or adjust the illumination direction of the main illumination part 3 and the subillumination part 4 suitably. Further, as the main illumination unit 3, various types of light sources may be employed instead of the LED lamps. Alternatively, as the sub-illumination unit 4, instead of the LED lamp, a combination of another type of light source and a reflecting plate may be adopted to give the sub-illumination unit 4 directivity. Moreover, you may make the color of the irradiation light of the main illumination part 3 and the subillumination part 4 mutually differ.

  Furthermore, a power source composed of a combination of a solar battery and a storage battery and a commercial AC power source may be selectively used, or only a commercial AC power source may be used.

  Moreover, you may change the shape and material of a support | pillar etc. suitably.
