It is characterized in that it is supported so as to be able to approach and separate from the supported separation position.

  In addition, the support body includes a lighting support portion that supports the back side of the lighting portion, a solar panel support portion that supports the back surface of the solar panel, and one end pivotally supported by the lighting support portion. It is preferable that the armature has an accommodating portion which is composed of an arm whose end is pivotally supported and accommodates the support at the joint position.

  Further, it is preferable that the accommodating portion is formed by a recess from the back side of the lighting portion, and the accommodating portion is located inside the outer peripheral surface of the lighting portion.

  In addition, it is preferable that the outer peripheral surface of the cylindrical lighting unit and the outer peripheral surface of the cylindrical solar panel be an integrated cylindrical body at the joining position.

  The accommodation section has a rotation area in which the arm rotates 90 degrees or more from the joint position, and rotates the arm 90 degrees or more as the detachment position, rotates the solar panel support section, and turns the solar panel to the illumination section. Is preferably located above the.

  In addition, it is preferable that the rear surface of the solar panel has an annular recess on the inner peripheral side of the outer peripheral edge.

  According to the invention as set forth in claim 1, the solar panel is extended by the support portion, and the direction of the solar panel can be separated from the irradiation direction of the illumination portion and can be independently changed. And the electricity can be stably stored by the solar panel. Further, the solar panel is located in a dead space such as above or behind the lighting unit, so that the sensor light can be made compact.

  According to the second aspect of the present invention, the solar panel can be positioned with a degree of freedom while the joint position and the detached position where the solar panel is detached are connected by the arm.

  The illuminating section 2 has a columnar shape having a certain length in the front-rear direction. The illuminating unit 2 is covered with a convex translucent plate 10 on the front surface to form an illuminating surface 2a, and includes a light source (not shown) made of an LED therein. The illuminating section 2 is capable of irradiating the light from the light source in a wide range by the light transmitting plate 10.

  On the back surface 2b of the lighting unit 2, as shown in FIG. 3, a small recess 2c into which a finger is inserted when the solar panel 3 is extended downward, and a housing portion having a large recess inside to accommodate the support 4 8 is provided. The small recess 2c has a semicircular shape and is formed on the lower edge of the illumination unit 2. In addition, as another embodiment, the accommodation unit 8 may be arranged on the solar panel 3 side.

  As described above, the housing portion 8 is a vertically long rectangular space that is largely recessed from the back surface 2b of the illumination portion 2. In the rear view of the illumination unit 2, the back surface 2 b is circular, and the vertical direction of the housing unit extends from near the center position (center of the circle) of the back surface 2 b to slightly near the upper edge of the back surface 2 b. Also, considering that the housing part 8 is divided into two parts on the left and right, the left part has a plate-shaped protection part 8a hanging from the upper edge, and the right part extends from the upper edge of the back surface 2b to a slightly lower part. The upper side of the housing portion 8 has a step. As will be described later, the protection part 8a protects the upper side of the lighting support part 5 of the support body 4, and is open to the right without the protection part 8a so that the arm 6 rotates 90 degrees or more from the accommodation position. The upper edge of the accommodating portion 8 is located lower (inner diameter side) than the outer peripheral surface of the illuminating portion 2 and is formed so as to be exposed to the outer peripheral side of the illuminating portion 2 so as not to be damaged by wind and rain.

  The support 4 includes a lighting support 5 connected to the lighting unit 2, a solar panel support 7 connected to the rear surface 3 b of the solar panel 3, and a long arm connecting the lighting support 5 and the solar panel support 7. 6 In the accommodation position, the illumination support part 5 is arranged on the upper left side of the accommodation part 8, the solar panel support part 7 is arranged on the lower left part, and the arm 6 is arranged on the right side of the accommodation part 8. With this configuration, it is possible to prevent the support 4 from protruding from the back surface 2b of the illumination unit 2 in the housed state, and to form the solar panel 3 and the illumination unit 2 into an integral cylindrical body.

  The lighting support part 5 is a part where the connection position with the lighting part 2 is rectangular and the surface on the solar panel 3 side is a curved surface, and is located at the upper left side of the housing part 8 as described above. The lighting support part 5 is made of a thick plate, and the left end face is opposed to the left inner side face of the housing part 8 with a gap in the left and right direction, and the right end face is located at the left and right center of the housing part 8 and is adjacent to the arm 6. ing. The illumination support portion 5 is formed so as to protrude from the bottom (front bottom surface) of the housing portion 8, and the tip (curved surface) is located inside the opening of the housing portion 8. The distal end of the lighting support 5 supports one end in the longitudinal direction of the arm 6 via a rotating shaft 4a having a left-right axial direction.

  The arm 6 has a thick plate shape longer than the illumination support portion 5, and has both edges in the longitudinal direction having a rounded arc shape to prevent interference due to rotation. The arm 6 is rotatable up and down in a region on the right side of the housing portion 8 about a connection portion (the rotation shaft 4a) with the illumination support portion 5 as a fulcrum. The left and right dimensions of the arm 6 are substantially the same as the left and right dimensions of the illumination support 5.

  The arm 6 is located at the accommodation position by arranging the arm 6 in the accommodation section 8 along the vertical direction, and fits on the right side in the accommodation section 8. In the storage position, the right end surface of the arm 6 faces the right inner side surface of the storage portion 8 with a gap left and right. The left end face of the arm 6 is located at the center in the left and right direction of the storage unit 8, and is adjacent to the lighting support unit 5 and the solar panel support unit 7.

  When the arm 6 is rotated from the accommodation position so that the other end in the longitudinal direction is located at the uppermost position, the arm 6 is positioned so that the longitudinal direction is slightly higher than the posture along the front-rear direction (90 degrees from the accommodation position). Can rotate up to about 100 degrees. In the rotating state, it is locked by contacting the upper side of the housing portion 8. The other end in the longitudinal direction of the arm 6 pivotally supports the solar panel support 7 via a rotating shaft 4b having an axial direction on the left and right.

  The solar panel supporting portion 7 is a portion having a rectangular connection position with the solar panel 3 and a curved surface on the side of the lighting unit 2. As described above, the solar panel supporting portion 7 is located at the lower left portion of the housing portion 8 in the housed state. , At the position facing the lighting connection unit 5. The connection portion is formed so as to protrude from the back surface 3b (front surface) of the solar panel 3 (see FIG. 4), and the tip portion (curved surface) is pivotally supported by the arm 6 by a rotation shaft 4b, and is rotatable up and down. In the storage position, the solar panel supporting portion 7 is located on the lower left side of the arm 6 in a posture parallel to the longitudinal direction of the arm 6, and is perpendicular to the posture parallel to the arm 6 when the arm 6 is rotated upward and extended. (90 degrees).

  In the storage position, the left end face of the solar panel support part 7 faces the left inner side surface of the storage part 8 with a gap in the left-right direction, and the right end face is located at the left and right center of the storage part 8. Further, the solar panel supporting portion 7 is pivotally supported at the accommodation position such that the right end face of the tip end faces the left end face of the other end of the arm 6 in the longitudinal direction.

  As shown in FIGS. 4 and 5, the solar panel 3 has a panel shape having a disk shape having substantially the same diameter as the illumination unit 2 and having a front surface 3 a (rear surface) of the disk as a light receiving surface. The solar panel 3 is brought into close contact with the back surface 2b so as to cover the back surface 2b of the illumination unit 2 in a state where the support body 4 is accommodated in the accommodation unit 8, and has an outer peripheral surface having the same diameter and a central axis. 2 together with a cylindrical body. Further, the solar panel 3 can be extended by the arm 6 of the support 4 to separate the back surface 3b from the back surface 2b of the illumination unit 2 and to be located at the detached position supported only by the arm 6 of the support 4. For example, as shown in FIG. 4, as one of the detached positions, when the arm 6 is turned 90 degrees while the solar panel supporting part 7 is being turned and is extended from the housing part 8, the solar panel 3 is placed above the lighting part 2. It can be mounted.

  In addition, as shown in FIG. 5, the solar panel 3 has a recess 11 that is annularly recessed in an inner peripheral portion of the back surface 3b from the outer peripheral edge. The inner peripheral end of the outer peripheral edge of the back surface 3b (the outer peripheral edge of the recess 11) is located on the inner peripheral side with respect to the upper edge of the housing portion 8 in a state in which the support 4 is housed, thereby stabilizing the back surface 3b of the solar panel 3. As a result, it is possible to come into contact with the back surface 2b of the lighting unit 2. Such a use example has an important effect when it is installed on an outdoor wall surface 20 such as an eaves or an entrance. That is, when the solar panel 3 is installed outdoors, the solar panel 3 is exposed to wind and rain, but there is a problem that the installation position of the solar panel 3 is shifted under various conditions such as rainfall. When the edge of the illumination unit 2 is engaged with the recess 11 on the back surface 3b as in the present embodiment, the installation position of the solar panel 3 can be maintained in the inclined position without shifting even under rainfall or snowfall conditions. Becomes possible.

  Also, the recess 11 makes it difficult for the rear surface 3b of the solar panel 3 and the rear edge of the illumination unit 2 to interfere with each other when the arm 6 is extended and retracted by the support 4, so that the position of the solar panel 3 is free. ing. For example, even if the arm 6 is rotated only with respect to the illumination support portion 5 from the state in which the solar panel support portion 7 is accommodated while being held at the angle of the accommodation state, the back surface 3 b interferes with the rear edge of the illumination portion 2. The solar panel 3 can be moved so as to be placed above the lighting unit 2 without the need for this. In addition, as shown in FIG. 6, the solar panel 3 can be arranged close to the lighting unit 2.

  Further, the back surface 3b of the solar panel 3 has a smaller cylindrical portion 3c on the inner peripheral side than the concave portion 11 and a smaller projecting amount than the outer peripheral side. The recess 11 has an annular outer circumferential surface and an inner circumferential surface that are inclined toward the bottom side, so that even when the recess 11 comes into contact with the rear edge of the illumination unit 2, the recess 11 is smoothly shifted to prevent damage.
