Mode for Carrying Out the Invention

[0016] Hereinafter, the stand light 10 as an electric device according to the present embodiment will be described with reference to the drawings. The arrows UP, FR, and RH appropriately shown in the drawings indicate the upper side, the front side, and the right side of the stand light 10, respectively. In the following description, when the up-down, front-rear, and left-right directions are used for explanation, unless otherwise specified, they indicate the up-down, front-rear, and left-right directions of the stand light 10.

[0017] As shown in FIGS. 1 and 2, the stand light 10 includes a stand part 20 (an element regarded as the main body of the device in a broad sense) and a light unit 70. The stand light 10 is configured to be switchable between a folded state (the state shown in FIG. 1) and an unfolded state (the state shown in FIG. 2) developed from the folded state. For example, when the stand light 10 is not in use, the stand light 10 is folded for storage. On the other hand, when the stand light 10 is in use, the unfolded stand light 10 is placed on the ground or the like to illuminate the surrounding area of the stand light 10. Hereinafter, each component of the stand light 10 will be described.

[0018] (Regarding the stand part 20) The stand part 20 includes a three-leg part 30, a head part 40, and a support pipe 50 as a support column.

[0019] (Regarding the three-leg part 30) The three-leg part comprises a lower end portion of the stand part 20. The three-leg part 30 includes a support column 31, a slide member 33, and three legs 34. The support column 31 is formed in a substantially cylindrical shape with the vertical direction as the axial direction. A battery mounting portion 32 is provided at the lower end of the support column 31, and the battery mounting portion 32 is formed in a hollow rectangular box shape. A battery (not shown) is accommodated in the battery mounting portion 32, and the battery is electrically connected to a control portion provided in the battery mounting portion 32. Then, power is supplied from the battery to a first light source 84 and a second light source 94 described later.

[0020] The sliding member 33 is formed in a substantially cylindrical shape with its axial direction in the vertical direction and is externally fitted onto the support column 31 so as to be movable in the vertical direction. Specifically, when the stand light 10 is folded, the sliding member 33 is located at the top of the support column 31, and when the stand light 10 is unfolded, the sliding member 33 is located at the bottom of the support column 31. A locking pin (not shown) is provided inside the sliding member 33, and the locking pin locks onto the support column 31, holding the sliding member 33 at the upper or lower end of the support column 31.

[0021] A tripod-side handle portion 33A is integrally provided on the sliding member 33. The tripod-side handle portion 33A extends vertically on the front side of the sliding member 33, and both longitudinal ends of the tripod-side handle portion 33A are bent to the rear and connected to the sliding member 33. A release button 36 is provided on the tripod-side handle portion 33A, and by operating the release button 36, the locking pin is released from its locking state to the support column 31.

[0022] The legs 34 are formed in a substantially elongated shape that extends vertically when the stand light 10 is folded, and are positioned radially outward of the slide member 33. Specifically, one leg 34 is positioned behind the slide member 33, and three legs 34 are arranged at equal intervals around the slide member 33. The upper end of each leg 34 is rotatably connected to the slide member 33, and the vertical middle portion of each leg 34 is connected to the lower end of the slide member 33 via a link member 35. By moving the slide member 33 from the upper end to the lower end of the support column 31, the lower end of each leg 34 moves radially outward of the slide member 33, causing the legs 34 to unfold.

[0023] (Regarding head section 40) As shown in Figures 1 to 5, the head portion 40 is formed as a roughly bottomed rectangular cylinder that is open upwards and fixed to the upper end of the support column 31. Specifically, the head portion 40 is composed of a head base portion 41 that constitutes the lower end of the head portion 40, a light cover portion 42 that serves as a cover portion that constitutes the upper end of the head portion 40, and a pair of left and right cover connecting portions 43 that connect the head base portion 41 and the light cover portion 42.

[0024] The head base portion 41 is formed in a roughly rectangular, flattened shape with the vertical direction being the thickness direction. The upper end of the support column 31 is fitted into a fixing hole (not shown) formed in the approximate center of the head base portion 41, thereby fixing the head base portion 41 to the upper end of the support column 31. A handle 41A is integrally provided on the head base portion 41. The handle 41A is formed in a roughly U-shape that is open to the rear in a plan view, and both longitudinal ends of the handle 41A are connected to the front end of the head base portion 41. The left-right dimension of the handle 41A is set to be slightly smaller than the left-right dimension of the head base portion 41.

[0025] A switch button 44 (see Figure 3) is provided in the middle of the front end of the head base portion 41 in the left-right direction. The switch button 44 is exposed upward from the head base portion 41 so that it can be pressed downward. A switch (not shown) operated by the switch button 44 is provided inside the head base portion 41, and the switch is electrically connected to the control unit.

[0026] The light cover section 42 is formed in a roughly stepped rectangular cylindrical shape that opens upwards. More specifically, the outer shape of the upper part of the light cover section 42 is set to be larger than the outer shape of the lower part of the light cover section 42. In the folded state, most of the light unit 70, which will be described later, is housed inside the light cover section 42, and the light cover section 42 covers the light unit 70 from both the front-to-back and left-to-right sides (see Figure 4).

[0027] The cover connecting portion 43 is integrally formed with the light cover portion 42, extends downward from both the left and right sides of the light cover portion 42, and is fastened and fixed to the head base portion 41. More specifically, the cover connecting portion 43 is formed in a substantially U-shape that is open upward when viewed from the side, the lower end of the cover connecting portion 43 is fastened and fixed to the left and right outer ends of the head base portion 41, and the upper end of the cover connecting portion 43 is connected to the front and rear ends of the left and right outer ends of the light cover portion 42.

[0028] (Regarding support pipe 50) As shown in Figure 2, the support pipe 50 extends vertically, and its upper end is covered by a pipe cap 56 (see Figure 1). The support pipe 50 has a double-pipe structure; in the folded state, the support pipe 50 is stored inside the support column 31, and in the unfolded state, the support pipe 50 extends upward from the head base portion 41. Specifically, the support pipe 50 has a lower extension pipe 51 as the lower pipe extending vertically, and an upper extension pipe 52 as the upper pipe. In the folded state, the lower extension pipe 51 is located inside the support column 31, and the upper extension pipe 52 is located inside the lower extension pipe 51. In addition, a cylindrical lower clamp portion 53 that protrudes upward is provided approximately in the center of the head base portion 41, and the lower extension pipe 51 is inserted into and supported by the lower clamp portion 53. Furthermore, an upper clamp portion 54, which is a cylindrical clamp portion, is provided at the upper end of the lower extension pipe 51, and the upper extension pipe 52 is inserted into the upper clamp portion 54 and supported by the upper clamp portion 54. When using the stand light 10, the lower extension pipe 51 is extended upward from the head base portion 41 by releasing the clamp state of the lower clamp portion 53 on the lower extension pipe 51. Similarly, the upper extension pipe 52 is extended upward from the lower extension pipe 51 by releasing the clamp state of the upper clamp portion 54 on the upper extension pipe 52. The lower clamp portion 53 and the upper clamp portion 54 are clamp members having a well-known lever-type clamping mechanism.

[0029] As shown in Figure 10, a cord insertion portion 52A is provided at the rear end of the upper end of the upper extension pipe 52. The cord insertion portion 52A is formed in the shape of a groove that extends vertically and penetrates in the front-to-back direction, and the upper end of the cord insertion portion 52A is open to the upper side. Three pipe-side fixing portions 52B are provided on the inner circumference of the upper extension pipe 52. In a plan view, the pipe-side fixing portions 52B are formed in the shape of a roughly C-shaped column that is open radially inward and extends vertically.

[0030] A wiring cord 55 connecting the control unit and the first light source 84 and the second light source 94 in the light unit 70 (described later) is inserted through the cord insertion section 52A. Specifically, the wiring cord 55 extending from the control unit is routed within the support column 31 and the support pipe 50, and also extends from the cord insertion section 52A to the outside of the upper extension pipe 52. Furthermore, the portion of the wiring cord 55 routed within the support column 31 and the support pipe 50, and the portion of the wiring cord 55 extending to the outside from the cord insertion section 52A, are configured as a so-called coiled cord (see Figures 4 to 6). As a result, the wiring cord 55 is configured to be retractable.

[0031] A cord bush 55A is provided on the outer circumference of the portion of the wiring cord 55 corresponding to the cord insertion portion 52A. The cord bush 55A is formed in a substantially cylindrical shape with the front-to-back direction as its axial direction. A flange 55B is formed at the front end of the outer circumference of the cord bush 55A, projecting radially outward. A bush groove 55C is formed on the outer circumference of the middle portion of the cord bush 55A in the front-to-back direction, behind the flange 55B. The bush groove 55C extends along the circumferential direction of the cord bush 55A and is formed around the entire circumference of the cord bush 55A. The edge of the cord insertion portion 52A is inserted into the bush groove 55C of the cord bush 55A, and the cord bush 55A is positioned within the lower end of the cord insertion portion 52A. As a result, the wiring cord 55 is assembled in a state where it is engaged in the front-to-back direction with the upper end of the upper extension pipe 52 (see Figures 4 and 8).

[0032] As shown in Figures 4, 6-8, and 10, the pipe cap 56 is made of resin and is provided on the upper end of the upper extension pipe 52. The pipe cap 56 is formed in a roughly stepped, bottomed cylindrical shape that is open to the bottom, and the outer diameter of the lower part of the pipe cap 56 is set to be larger than the outer diameter of the upper part of the pipe cap 56. The upper end of the upper extension pipe 52 is inserted into the pipe cap 56, and the upper end of the upper extension pipe 52 is covered by the pipe cap 56. Three fixing holes 56A are formed through the outer circumference of the upper wall of the pipe cap 56 at positions corresponding to the pipe-side fixing part 52B of the upper extension pipe 52. Fixing screws 58 are inserted into the fixing holes 56A from above and screwed into the inner circumference of the pipe-side fixing part 52B, thereby fixing the pipe cap 56 to the upper extension pipe 52.

[0033] The upper wall of the pipe cap 56 is integrally provided with a cap-side fixing portion 56B in the center for fixing the connecting cap 60, which will be described later. The cap-side fixing portion 56B is formed in a substantially stepped cylindrical shape with the vertical direction as the axial direction, and protrudes upward and downward from the upper wall of the pipe cap 56. The outer diameter of the lower part of the cap-side fixing portion 56B (the part that protrudes downward from the upper wall of the pipe cap 56) is set to be slightly larger than the outer diameter of the upper part of the cap-side fixing portion 56B (the part that protrudes upward from the upper wall of the pipe cap 56). A nut 57 is provided inside the lower part of the cap-side fixing portion 56B, and the nut 57 is integrally molded with the cap-side fixing portion 56B (pipe cap 56) by a method such as insert molding.

[0034] The lower end of the pipe cap 56 is located below the cord bush 55A of the wiring cord 55, and a notch 56C is formed at the lower end of the pipe cap 56 at a position corresponding to the cord bush 55A. The notch 56C is formed as a roughly inverted U-shaped groove that opens downward when viewed from the rear, and penetrates the pipe cap 56 radially. The cord bush 55A is positioned within the notch 56C and adjacent to the lower side of the upper inner circumferential surface of the notch 56C. As a result, the wiring cord 55 (cord bush 55A) is covered by the pipe cap 56 from above and on both sides in the circumferential direction of the upper extension pipe 52 (see Figure 6). In addition, when the upper extension pipe 52 is not extended, the upper clamp portion 54 is positioned adjacent to the lower side of the pipe cap 56, and the lower opening of the notch 56C is closed by the upper clamp portion 54 (see the upper clamp portion 54 shown by the dashed line in Figure 6).

[0035] An engaging piece 56D (see Figure 4) is provided on the inner circumferential surface of the upper end of the notch 56C, and the engaging piece 56D extends downward from the upper end of the notch 56C with the front-rear direction being the thickness direction of the plate. The engaging piece 56D is inserted from above into the bush groove 55C of the cord bush 55A, and the engaging piece 56D and the cord bush 55A are engaged in the front-rear direction.

[0036] (Regarding Light Unit 70) As shown in Figures 4 to 8, the light unit 70 is connected to the upper extension pipe 52 by a connecting cap 60, which serves as a pipe-side connecting part provided at the upper end of the upper extension pipe 52. The connecting cap 60 will be described first, followed by the light unit 70.

[0037] The connecting cap 60 is formed in a substantially cylindrical shape that is open to the bottom and is fitted onto the top of the pipe cap 56 from above. That is, the connecting cap 60 covers the top of the pipe cap 56 and the head of the fixing screw 58. A fixing recess 60A is formed in the center of the upper wall of the connecting cap 60, which is open to the top and protrudes to the bottom, and a fixing hole 60B is formed through the center of the bottom wall of the fixing recess 60A. The fixing recess 60A is positioned adjacent to the upper side of the cap-side fixing portion 56B of the pipe cap 56, and a fixing bolt 61 is inserted into the fixing hole 60B and screwed into the nut 57 of the pipe cap 56, thereby fixing the connecting cap 60 to the pipe cap 56.

[0038] A pair of left and right hinge shafts 60C are integrally provided on the outer circumference of the connecting cap 60. The hinge shafts 60C (see Figure 7) are formed in a substantially cylindrical shape with the left-right direction as the axial direction, and protrude outward from the connecting cap 60 in the left-right direction.

[0039] As shown in Figures 1 to 9, the light unit 70 is configured to include a first light 80 as a single light and a second light 90 as a pair of left and right lights. When using the stand light 10, it is configured to be switchable between a first state in which the first light 80 and the second light 90 face forward (the state shown in Figure 5), a second state in which the first light 80 faces forward and the second light 90 faces outward in the left and right directions (the state of the second light 90 shown by the dashed-dot line in Figure 5), and a third state in which the first light 80 and the second light 90 face upward (the state shown by the dashed-dot line in Figure 8). The configuration of the light unit 70 will be described below using the light unit 70 in the forward illumination state.

[0040] As shown in Figures 5 to 8, the first light 80 is composed of a first light section 81 which constitutes the front part of the first light 80 and a base section 82 which constitutes the rear part of the first light 80. The outer shell of the first light 80 is composed of a plurality of housing members, and the first light 80 is formed by assembling these housing members together. The outer shell of the first light section 81 is formed in a substantially rectangular box shape with the vertical direction as the longitudinal direction and opening to the front. A first light substrate 83 is provided inside the first light section 81, and the first light substrate 83 is formed in a rectangular plate shape with the front-to-back direction as the thickness direction and the vertical direction as the longitudinal direction. A first light source 84, which is a plurality of light sources composed of LEDs or the like, is provided on the front surface of the first light substrate 83. The first light source 84 is electrically connected to the control unit by a wiring cord 55 and irradiates the emitted light toward the front. Specifically, a wiring cord 55 extending from the upper extension pipe 52 is routed within the base portion 82 of the first light 80 and connected to the first light board 83. A light-transmitting light cover 85 is provided on the front side of the first light board 83, and the front opening of the first light unit 81 is closed by the light cover 85.

[0041] The base portion 82, when viewed from the rear, is formed in a hollow, roughly I-shaped block and protrudes to the rear from the vertically intermediate portion of the first light portion 81. Specifically, the base portion 82 is composed of a base body portion 82A extending in the vertical direction, a pair of left and right upper connecting portions 82B extending outward in the left and right direction from the upper end of the base body portion 82A, and a pair of left and right lower connecting portions 82C extending outward in the left and right direction from the lower end of the base body portion 82A (see Figure 6). The vertical dimension of the base body portion 82A is set to be smaller than the vertical dimension of the first light portion 81, and when viewed from the rear, the first light portion 81 protrudes above and below the base body portion 82A. The pair of left and right upper connecting portions 82B and lower connecting portions 82C protrude outward in the left and right direction from the first light portion 81.

[0042] At both ends of the base body 82A in the left-right direction, a pair of left and right hinge portions 82D are integrally provided in the middle section in the vertical direction, and the hinge portions 82D protrude rearward from the base body 82A. A counterbore portion 82E (see Figure 7) is formed at the rear end of the hinge portion 82D, which is open outward in the left-right direction, and a hinge hole 82F (see Figure 7) is formed through the bottom wall of the counterbore portion 82E in the left-right direction. The hinge portion 82D is positioned on the left-right outer side of the connecting cap 60, and the hinge shaft 60C is inserted into the hinge hole 82F, so that the base portion 82 is rotatably supported on the connecting cap 60 with the left-right direction as the axial direction. In other words, the light unit 70 is rotatably connected to the upper end of the upper extension pipe 52 with the left-right direction as the axial direction, and the first light 80 (first light portion 81 and base portion 82) is positioned in front of the upper extension pipe 52. This allows the light unit 70 to be switched between a forward-illuminating state and an upward-illuminating state by rotating the light unit 70 around the axis of the hinge shaft 60C. A screw 86 is threaded into the inner circumference of the hinge shaft 60C, and the light unit 70 is held in the forward-illuminating or upward-illuminating state by tightening the screw 86.

[0043] As shown in Figures 5, 6, and 9, the pair of left and right second lights 90 are configured symmetrically in the left-right direction. Therefore, the configuration of the second light 90 will be described below using the second light 90 positioned to the right of the first light 80. The second light 90 is composed of a second light section 91 which constitutes the front part of the second light 90, and a light connecting section 92 which serves as a connecting section that constitutes the rear part of the second light section 91. The outer shell of the second light 90 has a plurality of housing members, and the second light 90 is formed by assembling these housing members together.

[0044] The second light unit 91 has the same configuration as the first light unit 81. That is, the outer shell of the second light unit 91 is formed in a roughly rectangular box shape with the vertical direction as the longitudinal direction and opening to the front. The external shape of the second light unit 91 in a front view is set to be the same as the external shape of the first light unit 81. Inside the second light unit 91, a second light substrate 93 is provided, and the second light substrate 93 is formed in a rectangular plate shape with the front-to-back direction as the thickness direction and the vertical direction as the longitudinal direction. On the front surface of the second light substrate 93, a second light source 94 is provided, which is a plurality of light sources composed of LEDs or the like. The second light source 94 is electrically connected to the control unit by a wiring cord 55 and irradiates the emitted light toward the front. Specifically, the wiring cord 55 routed inside the base unit 82 of the first light 80 is routed inside the second light 90 and connected to the second light substrate 93. A light-transmitting light cover 95 is provided on the front side of the second light substrate 93, and the front opening of the second light unit 91 is closed by the light cover 95. In addition, the second light unit 91 is positioned adjacent to the right side of the first light unit 81, so that the base portion 82 of the first light 80 is not visible when viewed from the front.

[0045] The light connecting section 92 is formed as a hollow, roughly rectangular block extending in the vertical direction. The light connecting section 92 is provided with a pair of upper and lower connecting shafts 92A, which are formed as roughly cylindrical shapes with the vertical direction as their axial direction and protrude outward from the light connecting section 92 in the vertical direction. The light connecting section 92 is positioned between the upper connecting section 82B and the lower connecting section 82C of the first light 80, and the pair of upper and lower connecting shafts 92A are rotatably connected to the upper connecting section 82B and the lower connecting section 82C. As a result, the second light 90 is rotatably connected to the first light 80 with the vertical direction as its axial direction, and as shown in Figure 5, in the multi-directional illumination state, the second light 90 is rotated approximately 120 degrees to the rear, so that the second light 90 faces diagonally to the right rear. In other words, in the multi-directional illumination state, in a plan view, the light from the second light source 94 of the second light 90 is directed in a direction that intersects with the direction of illumination of the light from the first light source 84 of the first light 80. A screw 96 (see Figure 9) is screwed into the inner circumference of the light connecting part 92, and the screw 96 contacts the upper connecting part 82B and the lower connecting part 82C to fix the light in the forward illumination state or the multi-directional illumination state.

[0046] Furthermore, in the multi-directional illumination state, in a plan view, the intersection point P of the centerlines CL in the width direction (left-right direction) of the first light section 81 and the second light section 91 is located in front of the upper extension pipe 52 and overlaps with the base section 82. In addition, in the multi-directional illumination state, in a plan view, the left and right second light sections 91 are located outside the upper extension pipe 52 in the left-right direction. For this reason, for example, the stand light 10 can be used even when the light unit 70 in the multi-directional illumination state is rotated 90 degrees upward around the axis of the hinge shaft 60C.

[0047] Furthermore, when the light unit 70 is illuminating upwards, the base body portion 82A of the base portion 82 is positioned above the upper extension pipe 52. Also, as shown in Figure 4, when the stand light 10 is folded, the light unit 70 in the upward illuminating state is housed inside the light cover portion 42, and the light unit 70 is covered by the light cover portion 42 from both the front-to-back and left-to-right sides. Specifically, the rear of the first light portion 81 where the first light board 83 is housed, the rear of the second light portion 91 where the second light board 93 is housed, and the base portion 82 excluding the hinge portion 82D are covered by the light cover portion 42 from both the front-to-back and left-to-right sides.

[0048] (Effects and Benefits) Next, the operation and effects of this embodiment will be described.

[0049] When illuminating the area around the stand light 10 as described above, the stand light 10 is unfolded and the legs 34 of the tripod 30 are placed on the ground or other surface. This allows the stand light 10 to stand upright on the ground. The user can also operate the light unit 70 to illuminate forward, so that the first light section 81 and the second light section 91 face forward. Then, when the user presses the switch button 44, light is emitted forward from the first light source 84 and the second light source 94. Therefore, by placing the stand light 10 on the ground so that the object to be illuminated is located in front of the stand light 10, the object to be illuminated can be properly illuminated.

[0050] Furthermore, by operating the second light 90 relative to the first light 80, the second light unit 91 can be positioned to face diagonally outward and rearward in the left-right direction, thereby enabling the light unit 70 to illuminate in multiple directions. As a result, when viewed from above, the light from the first light source 84 and the second light source 94 can be emitted radially from the light unit 70 in three directions. Therefore, when illuminating the entire area around the stand lamp 10 simultaneously, the area around the stand lamp 10 can be well illuminated by setting the light unit 70 to the multi-directional illumination state.

[0051] As described above, according to the stand light 10 of this embodiment, the light unit 70 having a first light section 81 and a second light section 91 is configured to be switchable between a forward illumination state and a multi-directional illumination state. In the forward illumination state, the first light source 84 of the first light section 81 and the second light source 94 of the second light section 91 emit light forward. In the multi-directional illumination state, the first light source 84 emits light forward, and the second light section 91 is positioned so that, when viewed from above, the second light source 94 emits light diagonally outward and backward in the left and right directions. As a result, for example, by switching the light unit 70 between a forward illumination state and a multi-directional illumination state depending on the lighting configuration, the object to be illuminated can be effectively illuminated. Therefore, according to the stand light 10 of this embodiment, convenience can be improved.

[0052] Furthermore, in the forward-illuminating state of the light unit 70, the second light section 91 is positioned adjacent to the left-right outer side of the first light section 81, and the base section 82 is obscured from view from the front by the first light section 81 and the second light section 91. In other words, in the forward-illuminating state of the light unit 70, the first light section 81 and the second light section 91 are positioned in close contact in the left-right direction. Therefore, in the forward-illuminating state of the light unit 70, compared to the case where the first light section 81 and the second light section 91 are positioned spaced apart, the object to be illuminated in front can be illuminated more effectively.

[0053] In other words, when the light unit 70 is illuminating forward, if the first light section 81 and the second light section 91 are spaced apart in the left-right direction, the three light sections will be arranged side by side with a predetermined gap between them in the left-right direction, which may reduce the illuminance on the object being illuminated. In contrast, when the light unit 70 is illuminating forward, by arranging the first light section 81 and the pair of second light sections 91 in close proximity in the left-right direction, the first light section 81 and the pair of second light sections 91 can function as a single light section, illuminating the object being illuminated forward. Therefore, the illuminance on the object being illuminated can be increased. Accordingly, with the stand light 10 of this embodiment, when the light unit 70 is illuminating forward, the object being illuminated in front can be effectively illuminated.

[0054] Furthermore, the first light section 81 and the second light section 91 are arranged in a substantially rectangular shape with the left-right direction as the width and the up-down direction as the length when illuminating forward. Therefore, when the light unit 70 is illuminating forward, the light unit 70 can be made substantially square when viewed from the front. Thus, the light unit 70 can be miniaturized while effectively illuminating objects in front.

[0055] Furthermore, in the multi-directional illumination state, in a plan view, the intersection point P of the centerlines CL in the width direction of the first light section 81 and the second light section 91 is positioned in front of the upper extension pipe 52 and overlaps with the base section 82. Therefore, compared to, for example, the case where the intersection point P is positioned to overlap with the upper extension pipe 52 in a plan view, the increase in the size of the light unit 70 in the front-to-back direction in the multi-directional illumination state can be suppressed.

[0056] Furthermore, the base portion 82 is rotatably connected to the connecting cap 60 of the support pipe 50 in the left-right direction as the axial direction. By rotating the light unit 70 from the forward-illuminating state, the light unit 70 switches to an upward-illuminating state, in which case the first light source 84 and the second light source 94 emit light upwards. This makes it possible to switch the illumination direction of the light unit 70 in the up and down directions. Therefore, convenience for the user can be further improved. In addition, in the upward-illuminating state, the base portion 82 is positioned above the upper extension pipe 52. This makes it possible to stabilize the posture of the stand light 10 in the upward-illuminating state.

[0057] Furthermore, in the folded state, the light unit 70 is housed within the light cover portion 42 of the head portion 40, and the base portion 82 is covered by the light cover portion 42 from both the left-right and front-back sides. This improves the protective performance of the light unit 70 when the stand light 10 is not in use, for example. In particular, since the base portion 82 connecting the first light 80 and the second light 90 of the light unit 70 is covered by the light cover portion 42 from both the left-right and front-back sides, the connection between the first light 80 and the second light 90 can be well protected.

[0058] Furthermore, in the stand light 10, the wiring cord 55 extending from the light unit 70 is routed inside the support pipe 50 by passing it through the cord insertion portion 52A of the support pipe 50. Here, the upper end of the support pipe 50 is covered by a bottomed cylindrical pipe cap 56 that is open to the lower side. A groove-shaped notch 56C that is open to the lower side is formed at the lower end of the pipe cap 56, and the cord bush 55A of the wiring cord 55 is positioned inside the notch 56C. As a result, the pipe cap 56 can cover the wiring cord 55 (cord bush 55A) protruding from the support pipe 50 from above and from the outside in the circumferential direction of the support pipe 50 while closing the upper end opening of the support pipe 50. As a result, for example, it is possible to suppress the ingress of liquids such as water into the support pipe 50 from the cord insertion portion 52A, and to suppress the ingress of dust and other particles into the support pipe 50 from the cord insertion portion 52A. Therefore, the waterproof and dustproof properties of the stand light 10 can be improved.

[0059] Furthermore, in the support pipe 50, the upper extension pipe 52, which constitutes the upper part of the support pipe 50, is extendedly connected to the lower extension pipe 51, which constitutes the lower part of the support pipe 50. The lower end of the pipe cap 56 is located below the wiring cord 55 (cord bush 55A) protruding from the cord insertion part 52A, and in the non-extended state of the upper extension pipe 52, the upper clamp part 54 that holds the upper extension pipe 52 is positioned adjacent to the lower side of the pipe cap 56. This prevents the wiring cord 55 from being pinched between the pipe cap 56 and the upper clamp part 54 when the upper extension pipe 52 is not extended. Therefore, breakage of the wiring cord 55 can be suppressed.

[0060] Furthermore, the clamping force of the upper clamp portion 54 on the upper extension pipe 52 can be effectively applied. That is, in the support pipe 50 which has a double pipe structure, for example, a groove corresponding to the notch 56C of the pipe cap 56 can be formed at the upper end of the upper clamp portion 54, and the notch 56C of the pipe cap 56 can be omitted. In this case, the contact area between the upper clamp portion 54 and the upper extension pipe 52 is reduced by the groove corresponding to the notch 56C, so the clamping force of the upper clamp portion 54 on the upper extension pipe 52 may decrease. In contrast, in this embodiment, since the notch 56C is formed in the pipe cap 56, there is no need to form the groove in the upper clamp portion 54. As a result, the reduction in the contact area between the upper clamp portion 54 and the upper extension pipe 52 can be suppressed. Therefore, the clamping force of the upper clamp portion 54 on the upper extension pipe 52 can be effectively applied.

[0061] Furthermore, the pipe cap 56 is fastened and fixed to the upper extension pipe 52 by a fixing screw 58. This restricts the relative movement (rotation) of the pipe cap 56 with respect to the upper extension pipe 52. Therefore, it is possible to suppress, for example, disconnection of the wiring cord 55 caused by the relative movement of the pipe cap 56 with respect to the upper extension pipe 52. Thus, the reliability of the stand light 10 can be improved.

[0062] Furthermore, a connecting cap 60 for connecting the light unit 70 is provided at the upper end of the upper extension pipe 52. The connecting cap 60 is formed in a substantially bottomed cylindrical shape that is open to the bottom and covers the upper part of the pipe cap 56 and the fixing screw 58. Therefore, the connecting cap 60 for connecting the light unit 70 can be used to cover the pipe cap 56 and make the fixing screw 58 invisible. In other words, a double cover structure can be realized by using the connecting cap 60 and the pipe cap 56. Consequently, the waterproof and dustproof properties of the upper extension pipe 52 can be further enhanced, and the design of the stand light 10 can be improved.

[0063] Furthermore, a cord bush 55A is provided on the outer circumference of the wiring cord 55, and a bush groove 55C is formed on the outer circumference of the cord bush 55A. The edge of the cord insertion portion 52A is inserted into the bush groove 55C of the cord bush 55A, and the wiring cord 55 engages with the upper end of the upper extension pipe 52 in the front-rear direction (radial direction of the upper extension pipe 52). As a result, a so-called labyrinth structure is formed by the bush groove 55C and the edge of the cord insertion portion 52A, which effectively enhances the waterproof and dustproof properties of the upper extension pipe 52.

[0064] Furthermore, an engaging piece 56D is provided on the inner circumferential surface of the upper end of the notch 56C in the pipe cap 56, and the engaging piece 56D extends downward from the upper end of the notch 56C. The engaging piece 56D is inserted from above into the bush groove 55C of the cord bush 55A, and the engaging piece 56D and the cord bush 55A are engaged in the front-rear direction. As a result, a so-called labyrinth structure is formed by the bush groove 55C and the engaging piece 56D, which effectively enhances the waterproof and dustproof properties of the upper extension pipe 52.

[0065] In this embodiment, the light unit 70 is configured to be switchable between a forward illumination state and a multi-directional illumination state. However, the second light 90 may be positioned at any position between the forward illumination state and the multi-directional illumination state, and the stand light 10 may be used. Alternatively, the light unit 70 may be positioned at any position between the forward illumination state and the upward illumination state, and the stand light 10 may be used.
