[ outline of the Lighting device ]

Fig. 1 is a diagram schematically showing an illumination device 1 according to an embodiment. As shown in fig. 1, the lighting device 1 includes: a main body portion 2 including a weight 25, a light emitting portion 3 arranged above the main body portion 2 and emitting illumination light, a battery mounting portion 5 to which a battery 4 for an electric power tool is mounted, an upper grip 6 arranged so as to surround an upper portion of the main body portion 2, a lower grip 7 provided on the main body portion 2, a protruding portion 8 protruding from the main body portion 2, and an interface device 9. The lighting device 1 is installed in a work site such as a construction site or a construction site, an open place, or other places requiring illumination light. The lighting device 1 is operated by electric power supplied from a battery 4 for an electric power tool. Since the battery 4 for the electric power tool is used as the power source of the illumination device 1, the installation location of the illumination device 1 can be prevented from being limited. The user of the lighting device 1 can easily change the installation place of the lighting device 1.

The illumination device 1 is a self-return type illumination device that naturally returns to a predetermined posture even if the posture is changed by an external force in a state where the illumination device is installed on the installation surface FL in the predetermined posture. In a state where the illumination device 1 is disposed on the installation surface FL, for example, an external force may act on the illumination device 1 due to contact with an object. There is a possibility that the posture of the lighting device 1 is changed from a predetermined posture by an external force acting on the lighting device 1. There is a possibility that the lighting device 1 is tilted, for example, due to an external force acting on the lighting device 1. The lighting device 1 naturally returns to the predetermined posture even when it is tilted by an external force. In the embodiment, the predetermined posture is an upright posture in which the center line AX of the body 2 is parallel to the Z axis (vertical line). Even if an external force acts on the illumination device 1 so that the center line AX is inclined with respect to the Z axis, the posture of the illumination device 1 is restored so that the center line AX of the body 2 is parallel to the Z axis.

In the following description, the positional relationship of the respective portions will be described as a case where the lighting device 1 is maintained in the upright posture. That is, in the following description, the direction parallel to the center line AX is the Z-axis direction, the directions orthogonal to the center line AX are the X-axis direction and the Y-axis direction, and the plane orthogonal to the center line AX is the XY plane.

A dimension H of the body 2 in the Z-axis direction parallel to the centerline AX is larger than a dimension W of the body 2 in the X-axis direction and the Y-axis direction orthogonal to the centerline AX. That is, the main body 2 is long in the Z-axis direction. The light emitting unit 3 is disposed above the main body unit 2. Since the light emitting unit 3 is disposed at a high position, the lighting device 1 can sufficiently illuminate surrounding objects.

After the battery 4 and the battery mounting portion 5 are released from the fixed state, the battery 4 slides toward the opening 23 and is pulled out from the battery mounting portion 5. The battery 4 pulled out of the battery mounting portion 5 moves toward the opening 23 while being guided by the guide portion 12G. The battery 4 moves obliquely upward from the battery mounting portion 5 toward the opening 23. The battery 4 exits from the inner space 10 via the opening 23.

At least a part of the opening 23 is provided above the battery mounting portion 5 on the side surface 27 of the lower case 21. This allows the user to smoothly perform the work of inserting the battery 4 into the internal space 10 through the opening 23 and the work of withdrawing the battery 4 from the internal space 10 through the opening 23. The battery mounting portion 5 is inclined downward as it is farther from the opening 23. Thus, the battery 4 inserted into the internal space 10 from the opening 23 is mounted to the battery mounting portion 5 at the lower portion of the internal space 10. The battery 4 is mounted to the battery mounting portion 5 in the lower portion of the internal space 10, and therefore the center of gravity G of the lighting device 1 is maintained at a low position. Therefore, even if an external force acts on the lighting device 1 to change the posture of the lighting device 1, the lighting device 1 can naturally return to the upright posture.

[ Upper handle ]

As shown in fig. 1, 2, 3, 4, 5, 6, 8, 9, 10, 11, and the like, the lighting device 1 includes an upper handle 6 held by a user. The upper handle 6 is disposed to surround the upper portion of the main body 2. The upper handle 6 is an annular member disposed to surround the upper portion of the support portion 2B. The upper handle 6 is separated from the main body 2 and the light emitting unit 3. The upper handle 6 is coupled to the upper case 22 of the support portion 2B via a coupling member 6A. The connecting member 6A is a rod-shaped member. A plurality of coupling members 6A are disposed around the central axis AX. The coupling member 6A is coupled to the upper handle 6 and the upper case 22 such that the longitudinal direction of the coupling member 6A is parallel to the radial direction of the central axis AX. The plurality of coupling members 6A are arranged at regular intervals around the central axis AX. As shown in fig. 6, 4 coupling members 6A are disposed between the upper handle 6 and the upper case 22.

The center of the light-emitting portion 3 substantially coincides with the center of the upper handle 6 in an XY plane orthogonal to the center line AX. The outer shape of the upper handle 6 is larger than the outer shape of the light emitting portion 3 and smaller than the outer shape of the weight portion 2A in an XY plane orthogonal to the central axis AX.

Fig. 18 is a diagram showing a state in which the illumination device 1 according to the embodiment is placed on the installation surface FL. As shown in fig. 18, in a state where the upper handle 6 and the weight portion 2A are in contact with the flat installation surface FL, the light emitting portion 3 is separated from the installation surface FL.

Even if the lighting device 1 falls down, the contact of the light emitting section 3 with the installation surface FL can be suppressed by the upper handle 6. The upper handle 6 functions as a protective member that can prevent the light emitting section 3 from coming into contact with the installation surface FL even when the lighting device 1 falls down, and can protect the light emitting section 3.

[ lower handle ]

As shown in fig. 1, 2, 5, 6, 7, 11, 12, 13, and the like, the lighting device 1 includes a lower handle 7 held by a user. The lower handle 7 is disposed on the weight portion 2A. A recess 29 is provided in a part of the side surface 27 of the weight portion 2A. The lower handle 7 faces the inner surface of the recess 29 with a gap therebetween.

The lower handle 7 has an arc shape in an XY plane orthogonal to the central axis AX. The position of the lower handle 7 is substantially equal to the position of the boundary 27C in the Z-axis direction parallel to the center line AX. Both ends of the lower handle 7 are connected to the boundary 27C in the circumferential direction of the center line AX.

Fig. 19 is a diagram showing a state in which the lower handle 7 according to the embodiment is held by a user. As described above, the center of gravity G of the lighting device 1 is disposed in the weight portion 2A. The user holds the lower handle 7, thereby being able to hold at least a portion of the lighting device 1 near the center of gravity G.

[ protrusions ]

As shown in fig. 1, 2, 3, 4, 5, 6, 7, 8, 11, 13, and the like, the lighting device 1 includes the protrusion 8 provided in the weight portion 2A. The protrusion 8 protrudes outward in the radial direction of the center line AX from the side surface 27 of the weight 2A. The projection 8 is provided on the upper portion of the curved surface 27A of the weight 2A. The protrusion 8 may be provided on the boundary 27C. The plurality of protrusions 8 are arranged at intervals in the circumferential direction of the center line AX. The projection 8 may contact the installation surface FL in a state where the upper handle 6 and the weight 2A are in contact with the installation surface FL.

Fig. 20 is a diagram illustrating an operation of the protrusion 8 according to the embodiment. When the illumination device 1 is tilted and the upper handle 6 and the weight portion 2A contact the installation surface FL, the illumination device 1 may roll on the installation surface FL. When the lighting device 1 rolls, as shown in fig. 20, the projection 8 contacts the installation surface FL. This can suppress the lighting device 1 from continuing to scroll.

[ interface device ]

As shown in fig. 1, 2, 5, and the like, the lighting device 1 includes an interface device 9 provided on the main body portion 2. The interface device 9 is disposed on the surface of the support portion 2B (upper case 22). The interface device 9 is disposed above the door 24.

The interface device 9 includes an operation unit operated by a user at least for controlling the light emitting unit 3, and a display unit for providing a user with at least an operation state of the light emitting unit 3.

As shown in fig. 5, the interface device 9 has, as a display section, an intensity indicator 91 that displays the intensity of illumination light emitted from the light emitting section 3. The interface device 9 includes, as operation units, an intensity switching button 92 that changes the intensity of the illumination light emitted from the light emitting unit 3, a power button 93 that switches the power of the illumination device 1 on and off, and a lighting switching button 94 that switches the light source 31 to be lit among the plurality of light sources 31.

[ AC terminals ]

As shown in fig. 3, 4, 8, 13, and the like, the lighting device 1 includes an ac terminal 15. The ac terminal 15 is disposed below the side surface 27 of the weight portion 2A. The ac terminal 15 is connected to a commercial power supply (ac power supply) via a cable. The ac terminal 15 is covered with a cover 16.

That is, the lighting device 1 can use not only the battery 4 but also a commercial power supply as a power supply.

As shown in fig. 13, the ac terminal 15 includes an input terminal 15A and an output terminal 15B. The input terminal 15A is connected to a commercial power supply via a cable. The output terminal 15B is connected to the input terminal 15A of another lighting device 1 via a cable. In the embodiment, the plurality of lighting devices 1 can be connected in series via the ac terminal 15 and the cable.

As shown in fig. 3, 4, 8, 9, 11, and the like, the lighting device 1 includes a cable hook 14 for suspending a cable. The cable hook 14 includes a lower hook 14A provided on the surface of the weight portion 2A and an upper hook 14B provided on the surface of the support portion 2B. The upper hook 14B is disposed above the lower hook 14A. When the cable is not in use, it is wound around the cable hook 14.

[ Effect ]

As described above, the battery 4 for the electric power tool is used as the power source of the lighting device 1. This can prevent the installation location of the lighting device 1 from being limited. The user of the lighting device 1 can easily change the installation place of the lighting device 1.

In the self-return type lighting device 1 which naturally returns to the predetermined posture even when the posture is changed, the battery mounting portion 5 is inclined downward in the internal space of the main body portion 2 as it is farther from the opening 23. The battery mounting portion 5 is provided at a lower portion of the internal space 10. Thus, the battery 4 inserted into the internal space 10 from the opening 23 is mounted to the battery mounting portion 5 at the lower portion of the internal space 10. Since the battery 4 is mounted to the lower portion of the internal space 10 and to the battery mounting portion 5, the center of gravity G of the lighting device 1 is maintained at a low position. Therefore, even if an external force acts on the illumination device 1 and the posture of the illumination device 1 is changed, the illumination device 1 can naturally return to the predetermined posture. That is, since the battery mounting portion 5 is inclined downward as it is farther from the opening 23 and the battery mounting portion 5 is disposed below the main body portion 2, the self-recovery function of the lighting device 1 that naturally recovers to the predetermined posture can be suppressed from being damaged.

Further, since the battery mounting portion 5 is inclined downward as it is farther from the opening 23, the user can smoothly perform the work of mounting the battery 4 to the battery mounting portion 5 while moving the battery 4 obliquely downward and the work of removing the battery 4 from the battery mounting portion 5 while moving the battery 4 obliquely upward.

At least a part of the opening 23 is provided above the battery mounting portion 5 on the side surface 27 of the lower case 21. This allows the user to smoothly perform the work of inserting the battery 4 into the internal space 10 through the opening 23 and the work of withdrawing the battery 4 from the internal space 10 through the opening 23.

The guide rail 51 of the battery mounting portion 5 is inclined downward as it is farther from the opening 23. This allows the user to smoothly perform the work of mounting the battery 4 to the battery mounting portion 5 while moving the battery 4 obliquely downward, and the work of removing the battery 4 from the battery mounting portion 5 while moving the battery 4 obliquely upward.

The guide portion 12G is inclined downward as it is farther from the opening 23 between the opening 23 and the battery mounting portion 5, and guides the battery 4. Thus, even if the opening 23 is separated from the battery mounting portion 5, the user can smoothly perform the work of mounting the battery 4 to the battery mounting portion 5 while moving the battery 4 obliquely downward and the work of removing the battery 4 from the battery mounting portion 5 while moving the battery 4 obliquely upward by the guide portion 12G.

Battery mounting portion 5 is disposed in internal space 10 of weight portion 2A. Thereby, the center of gravity G of the lighting device 1 is maintained at a low position.

At least a part of the battery mounting portion 5 is disposed at the center of the weight portion 2A in an XY plane orthogonal to the center line AX. This can suppress the deviation of the weight balance of the illumination device 1 in the XY plane.

In the Z-axis direction parallel to the center line AX, the battery mounting portion 5 is disposed below a boundary 27C between the curved surface 27A and the inclined surface 27B. In a state of being mounted on the battery mounting portion 5, at least a part of the battery 4 is disposed below the boundary 27C. Thereby, the center of gravity G of the lighting device 1 is maintained at a low position. In a state where at least the curved surface 27A is in contact with the installation surface FL, the lighting device 1 can naturally return to a predetermined posture.

At least a part of the opening 23 is provided in the inclined surface 27B of the weight portion 2A. Thereby, at least a part of the opening 23 faces upward. Therefore, the user can smoothly perform the work of mounting the battery 4 to the battery mounting portion 5 while moving the battery 4 obliquely downward and the work of removing the battery 4 from the battery mounting portion 5 while moving the battery 4 obliquely upward.

The upper handle 6 is disposed to surround the upper portion of the main body 2. The user can carry the lighting device 1 by holding the upper handle 6. The user can easily change the installation place of the lighting device 1. In addition, the outer shape of the upper handle 6 is larger than the outer shape of the light emitting part 3 in an XY plane orthogonal to the center line AX. As described with reference to fig. 18 and the like, the contact between the light emitting unit 3 and the installation surface FL is suppressed in a state where the upper handle 6 and the weight 2A are in contact with the installation surface FL. This protects the light emitting section 3.

A lower handle 7 is provided on the weight portion 2A. As described with reference to fig. 19 and the like, the user can carry the lighting device 1 while holding the lower handle 7. The user can easily change the installation place of the lighting device 1. The center of gravity G of the illumination device 1 is disposed at the weight portion 2A. The user holds the lower handle 7, thereby being able to hold at least a portion of the lighting device 1 near the center of gravity G. Therefore, the user can smoothly carry the lighting device 1.

A recess 29 is provided on a side surface of the weight portion 2A. The lower handle 7 faces the inner surface of the recess 29 with a gap therebetween. Thereby, the user can insert the hand into the space between the lower handle 7 and the inner surface of the recess 29. Therefore, the user can smoothly carry the lighting device 1.

A projection 8 is provided on the upper portion of the curved surface 27A. The projection 8 projects outward in the radial direction of the center line AX. As described with reference to fig. 20 and the like, therefore, when the upper handle 6 and the weight 2A are in contact with the installation surface FL, the lighting device 1 can be prevented from continuing to roll.

A door 24 for opening and closing the opening 23 is provided. The upper portion of the door 24 and at least a part of the housing 20 are coupled via a hinge 24A. The door 24 functions as a shield for preventing foreign matter from entering the opening 23 from above the opening 23 in a state of being pivoted upward. This can prevent foreign matter from entering the internal space 10 through the opening 23. Therefore, for example, contamination of the battery mounting portion 5 can be suppressed.

A plurality of battery mounting portions 5 are provided. The battery 4 is mounted on each of the plurality of battery mounting portions 5, whereby the battery 4 can supply electric power for a long period of time. The battery 4 and the battery mounting portion 5 are detachable. Therefore, only one battery 4 or a plurality of batteries 4 can be used.

[ other embodiments ]

In the above-described embodiment, the battery mounting portion 5 is disposed below the boundary 27C in the internal space 10 of the weight portion 2A. Battery mounting portion 5 may be disposed above boundary 27C in internal space 10 of weight portion 2A.

In the above-described embodiment, the battery mounting portion 5 is disposed in the internal space 10 of the weight portion 2A. The battery mounting portion 5 may be disposed in the internal space 10 of the support portion 2B.

In the above-described embodiment, a plurality of battery mounting portions 5 are provided. The battery mounting portion 5 may be one. Even if there is one battery mounting portion 5, by disposing at least a part of the battery mounting portion 5 at the center of the weight portion 2A in the XY plane orthogonal to the center line AX, it is possible to suppress deviation of the weight balance of the illumination device 1.
