The second member includes a base that is disposed closing the other opening of the tubular shape and on which a light source is placed; a second lateral wall portion that is adjacent to a side end of the first lateral wall portion and continuous from the base, is part of a lateral wall of the tubular shape, and covers part of the peripheral edge of the circuit board; and a second divided connecting portion that is continuous with the second lateral wall portion and is part of the first connecting portion.
A portable lighting appliance disclosed in the embodiment includes a first tubular body including a first member and a second member, having a tubular shape when the first member and the second member are combined, including a first connecting portion on one opening side of the tubular shape, and including a circuit board inside the tubular shape; and a second tubular body having a tubular shape, the second tubular body including a first holding portion that holds the first connecting portion of the first tubular body and accommodating a power supply. The first member includes a first lateral wall portion that is part of a lateral wall of the tubular shape and covers part of a peripheral edge of the circuit board accommodated inside the tubular shape; and a first divided connecting portion that is continuous with the first lateral wall portion and is part of the first connecting portion. The second member includes a base that is disposed closing the other opening of the tubular shape and on which a light source is placed; a second lateral wall portion that is adjacent to a side end of the first lateral wall portion and continuous from the base, is part of a lateral wall of the tubular shape, and covers part of the peripheral edge of the circuit board accommodated inside the tubular shape; and a second divided connecting portion that is continuous with the second lateral wall portion and is part of the first connecting portion.
According to the embodiments of the present disclosure, it is possible to provide a lighting appliance tubular body and a portable lighting appliance that can be miniaturized.

Portable Lighting Appliance
A portable lighting appliance 100 according to an embodiment will be described with reference to
As illustrated in
Here, for example, the lighting appliance tubular body 1 includes a first tubular body 10 that includes a first member 11 and a second member 12, has a tubular shape when the first member 11 and the second member 12 are combined with each other, and includes a first connecting portion 15 on one opening side of the tubular shape; and a second tubular body 20 having a tubular shape, the second tubular body 20 including a first holding portion 22 that holds the first connecting portion 15 of the first tubular body 10 and accommodating the power supply B.
Further, the first member 11 includes a first lateral wall portion 11a and a first divided connecting portion 15a, and the second member 12 includes a base 13, a second lateral wall portion 14, and a second divided connecting portion 15b.
Further, in the lighting appliance tubular body 1 and the portable lighting appliance 100, for example, the second tubular body 20 is detachably attached to one side of the first tubular body 10, and the third tubular body 30 is detachably attached to the other side of the first tubular body 10. In addition, the first tubular body 10 includes a third holding portion 17 that holds a third tubular body 30 having a tubular shape on the peripheral edge of the base 13. The third tubular body 30 includes an accommodating portion 31 having a tubular shape that accommodates a lens 35, and a third connecting portion 32 that is continuous with the accommodating portion 31 and is detachably connected to the third holding portion 17. Further, the second tubular body 20 will be described as having a lid portion 40 detachably attached to the opposite side of the first tubular body 10. Configurations of the lighting appliance tubular body 1 and the portable lighting appliance 100 will be described below.
As illustrated in
In the first tubular body 10, the first connecting portion 15 having a tubular shape is disposed on the outer side of the first electrode 18a. Further, the first tubular body 10 supports the circuit board 60 such that the circuit board 60 is accommodated inside the tubular shape. The first connecting portion 15 is attached to the first holding portion 22 so as to be located on the inner side of the first holding portion 22, the second divided connecting portion 15b includes part of a screw portion that engages with a screw structure of the first holding portion 22, and the first divided connecting portion 15a includes a contact surface 15a1 that comes into contact with a top portion of the screw structure of the first holding portion 22. The first tubular body 10 can be formed of a metal such as Al, Cu, or SUS (stainless steel), or an alloy metal, or can be formed of a resin having a self-extinguishing property and impact resistance, such as PC (polycarbonate).
The first member 11 together with the second member 12 constitutes the first tubular body 10. The first member 11 includes a first lateral wall portion 11a that is part of a lateral wall of the tubular shape and covers part of the peripheral edge of the circuit board 60 accommodated inside the tubular shape, and a first divided connecting portion 15a that is continuous with the first lateral wall portion 11a and is part of the first connecting portion 15.
The first lateral wall portion 11a is an arc-shaped surface and has a size such that an upper end of the first lateral wall portion 11a comes into contact with a lower end side of the base 13 of the second member 12 and both side ends of the first lateral wall portion 11a come into contact with the second lateral wall portion 14 of the second member 12. The arc-shaped surface refers to a surface having an arc-shaped cross section. The first lateral wall portion 11a is formed so as to be a semicircular arc surface. For example, the first lateral wall portion 11a is adjacent to an annular outer peripheral surface 14a on the lower end side of the base 13. In addition, the third tubular body 30 side may be described as an upper side, and the second tubular body 20 side may be described as a lower side.
The first divided connecting portion 15a is a portion to be part of the first connecting portion 15 of the first tubular body 10. The first divided connecting portion 15a is disposed continuously from the first lateral wall portion 11a via a step so as to have a semicircular arc shape having a diameter smaller than a diameter of the semicircular arc of the first lateral wall portion 11a.
In the first divided connecting portion 15a, the contact surface 15a1 and the back surface of the contact surface 15a1, which are the arc-shaped surfaces, are smooth curved surfaces. The contact surface 15a1 having an arc shape of the first divided connecting portion 15a is disposed at the same height as the root portion of the thread formed on the second divided connecting portion 15b of the second member 12. Therefore, when the first divided connecting portion 15a together with the second divided connecting portion 15b is screwed as the first connecting portion 15 into the screw portion of the first holding portion 22, the first divided connecting portion 15a slides in a state of being in contact with the top portion of the thread of the first holding portion 22. As will be described below, the first holding portion 22 can detachably hold the first connecting portion 15 that is screwed from the outside. Therefore, the contact surface 15a1 of the first divided connecting portion 15a comes into contact with the inner peripheral end surface which is the top portion of the thread of the screw structure of the first holding portion 22.
In addition, the first divided connecting portion 15a includes, in a plate thickness portion serving as a side end surface of the contact surface 15a1, engagement holes 15a2 with which engagement pins 15b2 disposed protruding from a plate thickness portion serving as a side end surface of the second divided connecting portion 15b are engaged. The engagement holes 15a2 are formed in shapes corresponding to the shapes of the engagement pins 15b2, and here, the engagement holes 15a2 are formed in circular shapes in a plan view, for example.
The second member 12 together with the first member 11 constitutes the first tubular body 10. The second member 12 includes the base 13 that is disposed adjacent to the first lateral wall portion 11a, closing the other opening of the tubular shape, and on which the light source 50 is placed, the second lateral wall portion 14 that is adjacent to the side ends of the first lateral wall portion 11a and continuous from the base 13 to form the lateral wall of the tubular shape and covers part of the peripheral edge of the circuit board 60, and the second divided connecting portion 15b that is continuous from the second lateral wall portion 14 and is part of the first connecting portion 15.
The base 13 is disposed closing one opening of the tubular shape of the first tubular body 10, and the light source 50 is placed on the base 13. The base 13 includes the third holding portion 17 that holds the third tubular body 30 having a tubular shape, on a peripheral edge of the base 13. The base 13 has a flat placement surface 13a on which the light source 50 is placed, and the placement surface 13a is formed in a circular shape in a plan view, for example. The light source 50 is placed on the placement surface 13a by attaching a mounting substrate 51 of a light-emitting device 52 to the placement surface 13a with screws or the like. The placement surface 13a includes a through hole penetrating the base 13 in the plate thickness direction, so that a wiring line can be electrically connected to the light source 50.
As illustrated in
Further, the base 13 includes the third holding portion 17 at a position one step lower than the placement surface 13a. The third holding portion 17 has, for example, a screw structure; it includes a portion in which a screw is formed over a predetermined width on the outer peripheral surface at a position one step lower than the placement surface 13a. A portion with the screw structure of the third connecting portion 32 of the third tubular body 30 is screwed to the third holding portion 17 from the outside. Therefore, the first tubular body 10 and the third tubular body 30 can be detachably attached and detached by the third holding portion 17 and the third connecting portion 32.
Here, the third tubular body 30 connected to the first tubular body 10 accommodates the lens 35 therein as described below.
As illustrated in
The annular outer peripheral surface 14a is adjacent to the upper end of the first lateral wall portion 11a of the first member 11, and the arc-shaped outer peripheral surface 14b is disposed adjacent to the side ends of the first lateral wall portion 11a of the first member. The arc-shaped outer peripheral surface 14b is disposed having an arc length of a semicircular arc. This arc-shaped outer peripheral surface 14b and the first lateral wall portion 11a of the first member are combined to form a cylindrical shape, and the board support portion 16 is provided on the inner peripheral surface side of the arc-shaped outer peripheral surface 14b, whereby the circuit board 60 is accommodated and supported inside the tubular shape.
As an example, the board support portion 16 detachably supports the circuit board 60 by detachably fitting the circuit board 60 into the inner peripheral surface of the second lateral wall portion 14. Here, the board support portion 16 includes the first support portion 16a and the second support portion 16b that support the circuit board 60 when part of the peripheral edge of the circuit board 60 is fitted into the grooves. In the circuit board 60, a first board 61 is supported by the first support portion 16a, and a second board 62 is supported by the second support portion 16b. Note that the board support portion 16 does not need to be provided on the first lateral wall portion 11a as long as the board support portion 16 is provided on the second lateral wall portion 14. Thus, the structure of the first lateral wall portion 11a can be simplified.
The first support portion 16a has a groove portion in which a peripheral edge portion in a predetermined range in the circumferential direction of the first board 61 is fitted and supported, in the inner peripheral surface of the second lateral wall portion 14. The second support portion 16b has a groove portion in the inner peripheral surface of the second lateral wall portion 14 such that the second board 62 is supported at a position spaced apart from the first board 61 supported by the first support portion 16a. The first support portion 16a and the second support portion 16b each have a recessed groove portion in the thickness-wise direction along the second lateral wall portion 14 having the arc shape. Projecting portions can be provided in the groove portions of the second lateral wall portion 14 so as to be engaged with recessed portions 61a and 62a respectively provided in the first board 61 and the second board 62.
The first board 61 supported by the first support portion 16a is, for example, a board provided with a booster circuit. The second board 62 supported by the second support portion 16b is, for example, a board provided with a driver circuit of the light-emitting device 52. The second board 62 is formed including in advance an opening portion 62b formed by cutting out part of the disk shape such that the opening portion 62b has a fan shape. The opening portion of the second board can be used to improve the circulation of air in the tube and to dispose a wiring line, for example. In addition, the first support portion 16a and the second support portion 16b can be in contact with the electrode of the circuit board 60 inside the grooves, thereby allowing electrical connection with the power supply B.
The second divided connecting portion 15b constitutes the first connecting portion 15 together with the first divided connecting portion 15a of the first member 11. The second divided connecting portion 15b is disposed continuously from the second lateral wall portion 14 via a step so as to have a semicircular arc shape having a diameter smaller than a diameter of the semicircular arc of the second lateral wall portion 14.
The second divided connecting portion 15b includes a screw portion 15b1 in an arc-shaped portion thereof. Therefore, when the second divided connecting portion 15b together with the first divided connecting portion 15a is screwed as the first connecting portion 15 into the screw portion of the first holding portion 22, the second divided connecting portion 15b is screwed into the screw portion of the first holding portion 22. As will be described below, the first holding portion 22 can detachably hold the first connecting portion 15 when the first connecting portion 15 is screwed into the first holding portion 22 from the outside. Therefore, the screw portion 15b1 of the second divided connecting portion 15b is engaged with the screw portion of the first holding portion 22.
In addition, the second divided connecting portion 15b includes, on the plate thickness portion serving as the side end surface of the screw portion 15b1, the engagement pins 15b2 disposed protruding from the thickness portion so that the engagement pins 15b2 are fitted into the engagement holes 15a2 provided in the side end surface of the first divided connecting portion 15a. The engagement pins 15b2 are formed in shapes corresponding to the shapes of the engagement holes 15a2, and are formed in columnar shapes here, for example.
Alternatively, the engagement pin 15b2 can be provided as a member separate from the second divided connecting portion 15b, and the second divided connecting portion 15b can include an engagement hole with which the engagement pin 15b2 engages, in a plate thickness portion serving as a side end surface of the screw portion 15b1.
In the second member 12, the first electrode 18a serving as one of the power supply electrodes 18 is disposed in contact with one electrode of a battery serving as the power supply B in a direction in which the opening of the tubular shape is closed, on the inner side of the second divided connecting portion 15b.
The first electrode 18a is disposed in a plate shape substantially parallel to the first board 61 in the tube so as to be spaced apart from the first board 61 supported by the first support portion 16a. The first electrode 18a is formed in a semicircular shape or a major arc shape, and is disposed including a metallic electrode at the center of the tubular shape. For example, the first electrode 18a is disposed detachably fitted into the recessed groove provided on the inner peripheral surface side of the second member 12. In the first electrodes 18a, a circular metal piece with which the electrode of the power supply B comes into contact is disposed at a predetermined position of an insulating resinous substrate.
As illustrated in
For example, the second tubular body 20 is formed in a cylindrical shape, and serves as a portion of the portable lighting appliance 100 to be held by a user together with the first tubular body 10.
The second tubular body 20 can be formed of, for example, a metal such as aluminum (Al) or copper Cu, an alloy thereof, or a metal such as stainless steel (SUS).
Further, the first connecting portion 15 of the first tubular body 10 has a diameter smaller than a diameter of the tubular portion (outer lateral wall 10A) of the first tubular body 10, the first holding portion 22 of the second tubular body 20 is located on the outer side of the first connecting portion 15, and the tubular portion (outer lateral wall 20A) of the second tubular body 20 has substantially the same diameter as the diameter of the tubular portion (outer lateral wall 10A) of the first tubular body 10.
The first holding portion 22 detachably holds the first connecting portion 15 of the first tubular body 10, and has a screw structure as an example. The diameter of the first holding portion 22 is larger than the diameter of the first connecting portion 15, and the first holding portion 22 holds the first connecting portion 15 such that it is accommodated inside the tube. The screw structure of the second divided connecting portion 15b of the first connecting portion 15 is screwed into the first holding portion 22 and the contact surface 15a1 of the first divided connecting portion 15a of the first connecting portion 15 comes into contact with the top portion of the thread of the first holding portion 22, whereby the first holding portion 22 holds the first connecting portion 15.
The second holding portion 23 detachably holds the second connecting portion 41 of the lid portion 40. The second holding portion 23 has, for example, a screw structure that can correspond to the screw structure of the second connecting portion 41. The second holding portion 23 holds the second connecting portion 41 such that it is accommodated inside the tube. The second holding portion 23 detachably holds the second connecting portion 41 when the screw structure of the second connecting portion 41 is screwed into the second holding portion 23.
The third tubular body 30 is disposed connected to the first tubular body 10. The third tubular body 30 is disposed to accommodate the lens 35 therein and send light from the light source 50 to a distant place.
The outer lateral wall 30A of the third tubular body 30 is disposed so as to be substantially flush with the outer lateral wall 10A of the first tubular body 10 and the outer lateral wall 20A of the second tubular body 20.
The accommodating portion 31 includes a space for accommodating the lens 35 inside the tubular body formed in the cylindrical shape as an example. The accommodating portion 31 includes an uneven portion on the inner peripheral surface of the tube in accordance with the shape of the lens 35 so that the lens 35 does not move when the lens 35 is accommodated, and has a fixing groove 33 for fixing the peripheral edge of the tip surface of the lens 35, on the inner peripheral surface of the tube. The accommodating portion 31 is configured such that heat from the light source 50 is released. For example, an annular member 36 is disposed in the accommodating portion 31 in order to improve heat dissipation. In the annular member 36, the thickness on the nine-section side close to the light source 50 is increased to increase the surface area, thereby enhancing the heat dissipation.
As the lens 35, for example, a collimating lens that collimates light from the light source 50 is used. The lens 35 includes a flat irradiation surface 35a for emitting light at one end, an inclined surface 35b having a radius decreasing toward the other end opposite to the irradiation surface 35a, and a recessed portion 35c at the other end. The recessed portion 35c is disposed facing the light-emitting device 52 of the light source 50 such that light from the light-emitting device 52 enters the recessed portion 35c. Although the lens 35 is disposed such that the irradiation surface 35a for emitting light is directly exposed to the outside, a light-transmissive protective cover can be disposed in the fixing groove 33. When a disc-shaped protective cover is disposed, the fixing grooves 33 are disposed at two positions at an interval in the axial direction of the tubular shape; thus, the peripheral edge of the lens 35 is fixed in one of the fixing grooves 33, and the protective cover is fixed in the other fixing groove 33.
The lid portion 40 is detachably held by the second holding portion 23 of the second tubular body 20. The lid portion 40 includes the second connecting portion 41 that is detachably connected to the second holding portion 23, and a second electrode 18b that is in contact with the other electrode of the battery as the power supply B and serves as the other of the power supply electrodes 18. The lid portion 40 is formed having a size and a shape such that the outer lateral wall 40A of the lid portion 40 and the outer lateral wall 20A of the second tubular body 20 are flush with each other when the lid portion 40 is attached to the second tubular body 20. The lid portion 40 is, for example, a member that includes the second electrode 18b in contact with the other electrode of the power supply B and closes the opening on the other end side of the second tubular body 20. The lid portion 40 includes the second connecting portion 41 and a power switch 42. Here, the lid portion 40 includes a lid tubular body 45 including a first lid member 43 and a second lid member 44.
The second connecting portion 41 is detachably held by the second holding portion 23 of the second tubular body 20 via the screw structure. The screw structure of the second connecting portion 41 is disposed on the inner side of the second holding portion 23. The second connecting portion 41 is disposed on the second lid member 44.
The first lid member 43 is a disc-shaped member, and the power switch 42 is disposed at the center thereof. The first lid member 43 includes, on the peripheral edge side thereof, a first screw portion 43a detachable from the second screw portion 44a of the second lid member 44.
The lid tubular body 45 is detachable by screwing the first screw portion 43a of the first lid member 43 into the second screw portion 44a of the second lid member 44, and has a configuration facilitating the attachment work of the power switch 42 disposed inside the lid tubular body 45. The power switch 42 is a general switch that operates such that the second electrode 18b is pushed out and brought into contact with the power supply B to turn on the power supply when the power switch 42 is pressed, and the second electrode 18b is separated from the power supply B to turn off the power supply when the power switch 42 is pressed again.
As described above, the lighting appliance tubular body 1 and the portable lighting appliance 100 have the following operations and effects by including the members.
In the portable lighting appliance 100 and the lighting appliance tubular body 1, the first tubular body 10 is divided into the first member 11 and the second member 12, and a tubular shape is formed by combining the first member 11 and the second member 12, whereby the circuit board 60 having a size corresponding to the diameter of the tubular body can be incorporated. Therefore, it is not necessary to increase the size of one opening of the tubular body and accommodate the circuit board 60 from the opening, which eliminates the need to increase the size of the outer shape of the portable lighting appliance 100. That is, for the portable lighting appliance 100 and the lighting appliance tubular body 1, it is possible to reduce the overall size and achieve miniaturization. In addition, even in a case in which a plurality of boards such as the first board 61 and the second board 62 are used, since the first board 61 and the second board 62 can be supported by the board support portion 16 of the second member with a certain distance therebetween, it is possible to appropriately dissipate heat generated from the boards.
Further, the portable lighting appliance 100 can output light from the light source 50 via the lens 35 such that the light can reach, for example, a place 1 km or more away from the light source 50. That is, even if the external size of the portable lighting appliance 100 is small, by using the light-emitting device 52 such as an LD and providing the first board 61 provided with a booster circuit and the second board 62 provided with a driver circuit, it is possible to increase the output and make emitted light reach a distant place.
The lighting appliance tubular body 1 and the portable lighting appliance 100 have been described as having a cylindrical outer shape, but the outer shape is not limited to a cylindrical shape, and can be a rectangular tubular shape, a regular polygonal tubular shape, an elliptical cylindrical shape, or the like. Further, in the lighting appliance tubular body 1 and the portable lighting appliance 100, the first lateral wall portion 11a of the first member and the second lateral wall portion 14 of the second member have been described as having a semicircular arc shape in cross section, but one of them can have a minor arc shape and the other can have a major arc shape. Further, as long as the first lateral wall portion 11a and the second lateral wall portion 14 are combined to form a cylindrical shape (tubular shape), the first lateral wall portion 11a and the second lateral wall portion 14 can have bilaterally symmetrical shapes or bilaterally asymmetrical shapes.
In addition, the first divided connecting portion 15a includes the contact surface 15a1 that does not have a screw structure in a portion that is screwed into the first holding portion 22, but can have a screw structure. That is, the first connecting portion 15 can have a screw structure, and the first holding portion 22 can have a screw structure that detachably holds the first connecting portion 15. When the screw structure is provided, it is necessary to adjust the positions of the screw structure of the screw portion 15b1 of the second divided connecting portion 15b and the screw structure on the first divided connecting portion 15a side. When the first divided connecting portion 15a includes the contact surface 15a1 having no screw structure, the position adjustment of the screw structure is unnecessary. In the above description, the contact surface 15a1 is in contact with the top portion of the screw structure of the first holding portion 22; however, the contact is not essential, and a gap can be provided therebetween.
Further, for the sizes of the outer shapes of the first tubular body 10 and the second tubular body 20, for example, the first connecting portion 15 of the first tubular body 10 has a diameter smaller than a diameter of the tubular portion (outer lateral wall 10A) of the first tubular body 10, the first holding portion 22 of the second tubular body 20 is located on the outer side of the first connecting portion 15, and the tubular portion (outer lateral wall 20A) of the second tubular body 20 has a diameter smaller than the diameter of the tubular portion (outer lateral wall 10A) of the first tubular body 10. In this case, the lid portion 40 attached to the second tubular body 20 can have substantially the same diameter as the diameter of the tubular portion (outer lateral wall 20A) of the second tubular body 20, or can have substantially the same diameter as the diameter of the tubular portion (outer lateral wall 10A) of the first tubular body 10.
In the above description, the terms “substantially the same diameter”, “substantially flush”, and “substantially the same size” mean that one has a margin of error of ±3% with respect to the other. The expression “substantially the same diameter in the case of a non-circular shape” means that, for example, in the case of a quadrangular shape, a regular polygonal shape, or an elliptical shape, the outer shape is the same and the size of one shape has a margin of error of ±3% with respect to the size of the other shape. The first tubular body 10 can have a circular shape or a regular polygonal shape in a cross-sectional view in a direction orthogonal to an axis of the tubular shape, and the second tubular body 20 can have a circular shape or a regular polygonal shape in a cross-sectional view in a direction orthogonal to an axis of the tubular shape and have a size such that a battery can be accommodated inside the tubular shape. The outer shapes of the first tubular body 10, the second tubular body 20, the third tubular body 30, and the lid portion 40 can be different from each other.
Although the second member 12 includes the board support portion 16 for the circuit board 60 in the above description, the board support portion 16 can also be disposed in the first member 11.
Furthermore, the battery used as the power supply B can be a dry battery, a rechargeable battery, a button battery, or the like, as long as it has a size small enough for portable use. When a button battery is used, the length of the tubular main body 21 of the second tubular body 20 can be made equal to or shorter than when a dry battery is used. When a button battery is used, using a plurality of button batteries connected in series is preferable to using one button battery.
In addition, members which can be attached and detached by screw structures can be fixed so as to be non-detachable at a stage in which the portable lighting appliance 100 is completed.
