DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present teachings discloses an illumination system. The illumination system may include a light and a holder. The light may include: an illumination part from which light is emitted; a fixing part connected to the illumination part; and a battery mounting part to and from which a battery pack is attached and detached. The holder may include: a holder body; an attachment part connected to the holder body and to be attached to a subject; and an annular clamp unit connected to the holder body and disposed around the fixing part.

In the above structure, since the clamp unit of the holder is annular, the clamp unit is disposed around the fixing part of the light. As a result, the holder can stably hold the light that is heavy in weight when the battery pack is attached thereto. The subject to which the attachment part is attached is, for example, a hood (bonnet), a rear hatch, or a roof of an automobile, between cargo beds of a truck, between pipes, or a shelf.

In one or more embodiments, the fixing part of the light may be connected to an end of the illumination part.

In the above structure, the light emitted from the illumination part is prevented from being blocked by the fixing part.

In one or more embodiments, the light may include a handle unit. The fixing part may be disposed between the illumination part and the handle unit. The illumination system may include a plurality of the fixing parts. The fixing parts may be connected to the illumination part. At least one of the fixing parts may be disposed between the illumination part and the handle unit.

In the above structure, a user can grip the handle unit while the fixing part of the light is held by the clamp unit of the holder.

In one or more embodiments, the clamp unit may include a base part, an arm, a lock lever, and a spring. The base part may be disposed at a part of the circumference of the fixing part. The arm may be turnably connected to one end of the base part. The lock lever may be movably supported by the other end of the base part. The lock lever may lock the arm. The spring may apply an elastic force to the lock lever. The lock lever may be movable between a lock position at which the arm is locked and a release position at which the arm is unlocked. The spring may apply an elastic force to the lock lever in such a manner that the locking lever moves towards the lock position.

In the above structure, with the lock lever operated so as to move from the lock position to the release position against the elastic force of the spring, the lock of the arm is released, and an opening of the base part is opened. The user can insert the fixing part into the base part or remove the fixing part from the base part via the opening of the base part. In order that the fixing part is held by the clamp unit, the arm is operated so as to be pushed into the base part after the fixing part is inserted into the base part. With the arm operated so as to be pushed into the base part, the lock lever is pushed together with the arm toward the release position. Since the spring applies the elastic force to the lock lever in such a manner that the lock lever moves toward the lock position, the lock lever is pushed toward the release position together with the arm and then moves toward the lock position by the elastic force of the spring. As a result, the arm is automatically locked by the lock lever.

In one or more embodiments, the light may include a rotation unit that connects the illumination part and the battery mounting part in a relatively rotatable manner.

In the above structure, the orientation of the illumination part can be changed without changing the orientation of the battery pack. The emission direction of light emitted from the illumination part can be changed without changing the orientation of the battery pack.

In one or more embodiments, the attachment part of the holder may include a first attachment part and a second attachment part. The holder may include an extendable unit that connects the first attachment part and the second attachment part in a relatively movable manner.

In one or more embodiments, the light may include: an illumination part from which light is emitted; and a fixing part connected to an end of the illumination part. The light holding part may have an annular shape that surrounds the fixing part.

In the above structure, since the light holding part has an annular shape to surround the fixing part of the light, the fixing part of the light hardly comes off from the light holding part.

In one or more embodiments, the light holding part may include: a base part to be disposed at a part of the circumference of the fixing part; an arm turnably connected to one end of the base part; a lock lever that is movably supported by the other end of the base part and is capable of locking the arm; and a spring that applies an elastic force to the lock lever. The lock lever may be movable between a lock position at which the arm is locked and a release position at which the arm is unlocked. The spring may apply an elastic force to the lock lever in such a manner that the locking lever moves towards the lock position.

In the above structure, with the lock lever operated so as to move from the lock position to the release position against the elastic force of the spring, the lock of the arm is released, and an opening of the base part is opened. The user can insert the fixing part into the base part or remove the fixing part from the base part via the opening of the base part. In order that the fixing part is held by the light holding part, the arm is operated to so as to be pushed into the base part after the fixing part is inserted into the base part. With the arm operated so as to be pushed into the base part, the lock lever is pushed together with the arm toward the release position. Since the spring applies the elastic force to the lock lever in such a manner that the lock lever moves toward the lock position, the lock lever is pushed toward the release position together with the arm and then moves toward the lock position by the elastic force of the spring. As a result, the arm is automatically locked by the lock lever.

Clamp Unit

FIG.3is a perspective view illustrating the second clamp unit17B and the second attachment part16B of the embodiment.FIG.4is a perspective view illustrating the second clamp unit17B of the embodiment.FIG.5is a cross-sectional view illustrating the second clamp unit17B of the embodiment. The first clamp unit17A and the second clamp unit17B have equivalent structures. Hereinafter, the second clamp unit17B will be mainly described, and description of the first clamp unit17A will be simplified or omitted.

The second clamp unit17B includes a base part171, an arm173, a lock lever174, and a spring175.

The base part171is to be disposed on a part of the circumference of the fixing part19. The base part171includes an arcuate part171A, a protrusion171B protruding upward from the arcuate part171A, and a slide part171C disposed in a guide groove151provided in the holder body15. In addition, the base part171has: a hole171D formed to penetrate the protrusion171B; and a housing part171E in which at least a part of the lock lever174and the spring175are housed. The housing part171E is connected to the external space via the opening171F. A screw177is disposed in the hole171D via a bush176. With the screw177coupled to a screw hole provided in the holder body15, the second clamp unit17B is fixed to the holder body15.

The arm173is turnably connected to one end (first end) of the base part171via a turning part172. The arm173has a substantially arc shape.

The lock lever174is movably supported by the other end (second end) of the base part171. The lock lever174can lock the arm173. The lock lever174includes an operation part174A disposed on an outer side with respect to the outer curved surface of the arcuate part171A, a moving portion174B disposed inside the housing part171E, a protrusion174C inserted into a lower end of the spring175, and a pin174D provided to the moving portion174B. The lock lever174is movable between a lock position Pa at which the arm173is locked and a release position Pb at which the arm173is unlocked. The movement range of the lock lever174is defined by an opening171F. The lock position Pa is defined below the release position Pb. A position where at least a part of the lock lever174abuts against the lower end of the opening171F is the lock position Pa. A position where at least a part of the lock lever174abuts against the upper end of the opening171F is the release position Pb. As illustrated inFIG.5, in a state where the lock lever174is disposed at the lock position Pa, a recess173A provided in a distal end of the arm173is hooked on the pin174D, whereby the arm173is locked.

The spring175applies an elastic force to the lock lever174. The spring175is in contact with at least a part of the lock lever174. The spring175is disposed in the housing part171E. An upper end of the spring175is in contact with an upper wall surface171G of the housing part171E of the base part171. The lower end of the spring175is in contact with a support surface174E provided in the moving portion174B of the lock lever174. The spring175is disposed between the upper wall surface171G and the support surface174E in a compressed state. The spring175applies the elastic force to the lock lever174in such a manner that the lock lever174moves toward the lock position Pa. The pin174D presses the recess173A by the elastic force of the spring175.

Each ofFIGS.6and7is a cross-sectional view for explaining the operation of the second clamp unit17B of the embodiment.

To release the lock of the arm173by the lock lever174, as illustrated inFIG.6, the operation part174A is operated such that the lock lever174moves from the lock position Pa to the release position Pb. That is, the lock lever174is moved in a direction indicated by an arrow Ya inFIG.6. The user moves the lock lever174from the lock position Pa to the release position Pb against the elastic force of the spring175. With the lock lever174moving to the release position Pb, the pin174D is detached from the recess173A. As a result, the lock by the lock lever174is released. When the lock is released, the arm173turns in a direction indicated by an arrow Ra. As a result, as illustrated inFIG.7, the base part171and the arm173are separated. The user can insert the fixing part19into the inside of the base part171or remove the fixing part19from the inside of the base part171. When the user releases the lock lever174, the lock lever174returns to the lock position Pa due to the elastic force of the spring175as illustrated inFIG.7.

In order that the second clamp unit17B holds the fixing part19; after disposing the fixing part19inside the base part171, the user operates the arm173such that the arm173turns in the direction indicated by the arrow Rb illustrated inFIG.6. With the arm173turning in the direction indicated by the arrow Rb, the pin174D is disposed in the recess173A. The spring175applies the elastic force to the lock lever174such that the lock lever174moves toward the lock position Pa. Therefore, after the pin174D is hooked on the recess173A, the lock lever174moves in the direction indicated by the arrow Yb by the elastic force of the spring175. As a result, the pin174D is hooked on the recess173A, and the arm173is locked by the lock lever174.

Rotation Unit

FIG.8is a perspective view for explaining the operation of the rotation unit14of the embodiment. InFIG.8, a first state is a state in which the light emitting plane7B and the light emitting plane9B face downward. In a state where the attitude (orientation or the like) of the holder3and the attitude (orientation or the like) of the battery pack12are maintained by the rotation unit14; for example, it is possible to shift to a second state in which the light emitting plane7B and the light emitting plane9B face rearward. In a case where the rotation unit14is not included, for example, when the light2is rotated such that the light emitting plane7B and the light emitting plane9B face rearward, the battery pack12also rotates. The weight of the battery pack12is heavy. Therefore, even when the light2is rotated such that the light emitting plane7B and the light emitting plane9B face rearward, there may be a possibility that the entire light2rotates such that the light emitting plane7B and the light emitting plane9B face, for example, downward due to the gravity (action of gravity) on the battery pack12. In the embodiment, in a state where the attitude of the battery pack12is maintained by the rotation unit14, the user can rotate a part of the light2to shift from, for example, the first state in which the light emitting plane7B and the light emitting plane9B face downward to the second state in which the light emitting plane7B and the light emitting plane9B face rearward. The light emitting plane7B and the light emitting plane9B can face any direction without being affected by the weight of the battery pack12.

FIG.9is a perspective view illustrating the rotation unit14of the embodiment. The rotation unit14connects the illumination part7and the illumination part9to the handle unit11provided with the battery mounting part13in a relatively rotatable manner about a rotation axis CX parallel to a left-right axis. The rotation unit14includes a fixing ring141that rotatably supports the fixing part19, a rotation plate142that rotates together with the fixing part19, a lock pin144that is inserted in a hole143included in the rotation plate142, and a spring145that applies an elastic force to the lock pin144such that the lock pin144is inserted into the hole143. The lock pin144and the spring145are disposed in an internal space of the handle unit11. The lock pin144and the spring145are supported by the handle unit11via a support member146. A plurality of the holes143is provided around the rotation axis CX. The holes143are provided, for example, at intervals of 45 degrees-apart around the rotation axis CX. The user can rotate the rotation plate142via the fixing part19against the restriction force of the lock pin144and the elastic force of the spring145. When the lock pin144and any one of the holes143coincide in position with each other while the rotation plate142is rotated, the lock pin144is inserted into that hole143. Insertion of the lock pin144into the hole143prevents rotation of the rotation plate142. That is, by inserting the lock pin144into the hole143, the rotation plate142is positioned in the rotation direction. The user can rotate the rotation plate142such that the handle unit11provided with the battery mounting part13forms any angle with respect to the illumination part7and the illumination part9.

Extendable Unit

FIG.10is a cross-sectional view illustrating the holder3of the embodiment. The holder3includes an extendable unit20that connects the first attachment part16A and the second attachment part16B in a relatively movable manner. The relative distance between the first attachment part16A and the second attachment part16B is changed by the extendable unit20. The extendable unit20is disposed inside the holder body15and includes a spring21that connects the first attachment part16A and the second attachment part16B. One end (right end) of the spring21is connected to the first attachment part16A via a coupling member22A. The other end (left end) of the spring21is connected to the second attachment part16B via a coupling member22B. The spring21generates an elastic force such that the first attachment part16A and the second attachment part16B approach each other. In a case of mounting the holder3to a subject S having a wide width, a user separates the first attachment part16A and the second attachment part16B from each other against the elastic force of the spring21and then hooks the first attachment part16A on a right end of the subject S and the second attachment part16B on a left end of the subject S. As a result, the subject S is clamped between the first attachment part16A and the second attachment part16B, and the holder3is attached to the subject S.

Bent Unit

FIG.11is a perspective view for explaining the operation of the bent unit6of the embodiment. As illustrated inFIG.11, the bent unit6relatively turns the first light unit4and the second light unit5. The bent unit6turns the first light unit4and the second light unit5in such a manner that the light emitting plane7B of the first light unit4and the light emitting plane9B of the second light unit5do not face each other.

FIG.12is a perspective view illustrating the bent unit6of the embodiment. The bent unit6includes: a first fixing part61fixed to the second light unit5; and a second fixing part62fixed to the first light unit4. The first fixing part61includes: a cap part61A to be mounted to the second light unit5and fixed to the second light unit5by screws63; and a turning part61B. The second fixing part62includes a cap part62A to be mounted to the first light unit4and fixed to the first light unit4by screws64and a turning part62B. The turning part61B and the turning part62B are supported by a hinge unit60. The hinge unit60includes: a lock pin65that locks the turning part62B via the turning part61B; and a spring66that applies an elastic force to the lock pin65in such a manner that the lock pin65is pressed against the turning part62B.

For example, a user can turn the first light unit4with respect to the second light unit5against the regulating force of the lock pin65and the elastic force of the spring66. When the lock pin65and a positioning hole (not illustrated) included in the turning part62B coincide with each other while the first light unit4is turned, the lock pin65is inserted into the positioning hole. With the lock pin65inserted in the positioning hole, the first light unit4is positioned in the turning direction. The user can relatively rotate the first light unit4and the second light unit5so that the first light unit4and the second light unit5are put in a state (straight state) in which the first light unit4and the second light unit5extend straight or a state (bending state) in which the first light unit4and the second light unit5are turned.

Switch

FIG.26is a diagram illustrating the handle unit11of the light2of the embodiment. As illustrated inFIG.26, a main power switch100, an irradiation mode changeover switch101, and a color temperature changeover switch102are arranged in the handle unit11.

The main power switch100is operated in order to switch on and off the light2. The main power switch100is operated in order to change the luminance of the light2. When the main power switch100is operated once in an off state, the light2is turned on in a high luminance mode. When the main power switch100is operated once in a state where the light2is on in the high luminance mode, the light2is turned on in a medium luminance mode. When the main power switch100is operated once in a state where the light2is on in the medium luminance mode, the light2is turned on in a low luminance mode. When the main power switch100is operated once in a state where the light2is on in the low luminance mode, the light2is turned off.

The irradiation mode changeover switch101is operated in order to change the irradiation mode of the light2. The irradiation mode of the light2includes an all-on mode in which both the first light unit4and the second light unit5are turned on, a first half-on mode in which the first light unit4is turned on and the second light unit5is turned off, and a second half-on mode in which the second light unit5is turned on and the first light unit4is turned off. When the main power switch100is operated once in the off state, the light2is turned on in an irradiation mode as of the time when the light was turned off last time. For example, when the main power switch100is operated in order to turn on the light2after the main power switch100has been operated to turn off the light2in the all-on mode, the light2is turned on in the all-on mode. When the irradiation mode changeover switch101is operated once in the all-on mode, the light2is turned on in the second half-on mode. When the irradiation mode changeover switch101is operated once in the second half-on mode, the light2is turned on in the first half-on mode. When the irradiation mode changeover switch101is operated once in the first half-on mode, the light2is turned on in the all-on mode.

The color temperature changeover switch102is operated in order to change the color temperature of light emitted from the light2. The color temperature of the light emitted from the light2includes daylight white, a warm color, and an intermediate color. When the main power switch100is operated once in the off state, light having a color temperature as of the time when the light was turned off last time is emitted from the light2. For example, when the main power switch100is operated to turn off the light2in a state where the light2emits daylight white light and then the main power switch100is operated to turn on the light2, the color temperature of the light emitted from the light2is daylight white. When the irradiation mode changeover switch101is operated once in a state where daylight white light is emitted from the light2, warm light is emitted from the light2. When the irradiation mode changeover switch101is operated once in a state where warm color light is emitted from the light2, intermediate color light is emitted from the light2. When the irradiation mode changeover switch101is operated once in a state where intermediate color light is emitted from the light2, daylight white light is emitted from the light2.

The light2includes: the illumination part7and the illumination part9from which light is emitted; the fixing part18connected to the illumination part7and the fixing part19connected to the illumination part9; and the battery mounting part13to and from which the battery pack12is attached and detached. The holder3includes: the holder body15; the attachment parts16connected to the holder body15and to be attached to the subject S; and the annular clamp units17each connected to the holder body15and respectively arranged around the fixing parts18and19.

In the above structure, since the clamp units17of the holder3are annular, the clamp units17are respectively arranged around the fixing parts18and19of the light2. As a result, the holder3can stably hold the light2that is heavy in weight when the battery pack12is attached.

In the embodiment, the fixing parts18and19of the light2are respectively connected to ends of the illumination parts7and9.

In the above structure, the light emitted from the illumination parts7and9is prevented from being blocked by the fixing parts18and19.

In the embodiment, the light2include the handle unit11. The fixing part18is connected to the illumination part7, and the fixing part19is connected to the illumination part9. Among the fixing parts18and19, at least the fixing part19is disposed between the illumination part9and the handle unit11.

The spring175applies the elastic force to the lock lever174in such a manner that the lock lever174moves toward the lock position Pa.

In the above structure, with the lock lever174operated so as to move from the lock position Pa to the release position Pb against the elastic force of the spring175, the lock of the arm173is released, and the opening of the base part171is opened. The user can insert the fixing part18or19into the base part171or remove the fixing part18or19from the base part171via the opening of the base part171. In order that the fixing part18or19is held by the clamp unit17, the arm173is operated so as to be pushed into the base part171after the fixing part18or19is inserted into the base part171. With the arm173operated so as to be pushed into the base part171, the lock lever174is pushed together with the arm173toward the release position Pb. Since the spring175applies the elastic force to the lock lever174in such a manner that the lock lever174moves toward the lock position Pa, the lock lever174is pushed toward the release position Pb together with the arm173and then moves toward the lock position Pa by the elastic force of the spring175. As a result, the arm173is automatically locked by the lock lever174.

In the embodiment, the light2includes the rotation unit14that connects the illumination parts7and9to the battery mounting part13in a relatively rotatable manner.
