However, there is a problem that not only is it very difficult to control the operation of multiple lighting devices at once, but also the position setting control due to a sudden power cut is difficult.

[0005] In particular, when the lighting device is equipped with a spot light that emits a narrow beam, it is common to mount a large number of LED elements densely in a small area to increase the light distribution effect.

[0076] A lighting device (1) according to one embodiment of the present invention includes, as referenced in FIGS. 1A to 6B, a lighting body (110) having a vertical cross-section shape of approximately a rectangle (or square), but having a very slim thickness in the front-back direction and an open front, and an LED unit (150) that is mounted and coupled to an installation space (110S) provided on the inside of the lighting body (110) and includes an LED substrate (151) on which a plurality of LED elements (155) are mounted.

[0077] In the front part of the lighting body (110), an installation space (110S) for stacking and installing the LED unit (150) described above is provided in the form of a groove with the front side open, and in the back part of the lighting body (110), a plurality of press-fitting portions (130) for press-fitting and installing the heat dissipation unit (200) described later can be integrally formed.

[0078] In addition, a plurality of screw fastening holes (112h) for screw assembly of the light-emitting panel (120) described later may be formed at a distance from each other on the front edge of the lighting body (110).

[0079] Meanwhile, a lighting device (100) according to one embodiment of the present invention, as referenced in FIGS. 3A to 6B, is made of a transparent material (or a translucent material) that transmits light generated from an LED unit (150) forward, but may further include a light-transmitting panel (120) that shields the open front of the lighting body (110).

[0080] More specifically, the light-emitting panel (120) may include a light-emitting glass (121) provided in the form of a panel made of a transparent material (or a translucent material), as shown in FIGS. 6A and 6B, a fixing frame (123) that mediates screw assembly of the light-emitting glass (121) to the front end of the lighting body (110) using a plurality of fixing screws (127), and a waterproof gasket (125) that is interposed between the fixing frame (123) and the front end edge of the lighting body (110) and performs a waterproof function.

[0081] At the edge end of the fixed frame (123), a plurality of screw penetration holes (129h) may be formed at positions corresponding to a plurality of screw fastening holes (112h) formed at the front end of the lighting body (110) so that the above-described fixing screws (127) may pass through.

[0082] Here, the waterproof gasket (125) is made of rubber material, and when the fastening force of the fixing screw (127) is provided to the fixing frame (123), it is compressed and deformed, thereby preventing foreign substances including rain from entering the interior.

[0083] Meanwhile, a plurality of press-fitting portions (130) can be integrally formed on the back surface of the lighting body (110) as described above.

[0084] A plurality of press-fit portions (130) are provided as a portion where a plurality of heat dissipation units (200) described later are detachably installed, and are provided in the form of a pair of slot ribs (130a, 130b) whose ends protrude rearward by a predetermined length from the rear surface of the lighting body (110), and the heat dissipation unit (200) can be installed by being press-fitted so that a part thereof (e.g., a part of the refrigerant flow space (205) described later) is positioned within an installation groove (130h) formed between the pair of slot ribs (130a, 130b).

[0085] The heat dissipation unit (200) is a component corresponding to a core heat dissipation means of an electronic device, such as a lighting device (100) according to one embodiment of the present invention, which generates a lot of heat during operation and whose lifespan is determined by whether the heat is quickly dissipated to the outside. The most important design element is to design it so that no temperature deviation occurs between the LED elements (155) constituting the LED unit (150).

[0086] In particular, in the case of spot lighting equipped to emit a narrow beam, there is an even greater need for a layout design of a heat dissipation unit (200) to densely mount small-sized light sources (LED elements) while minimizing temperature deviation.

[0087] A lighting device (100) according to one embodiment of the present invention may further include a plurality of heat dissipation units (200) that are press-fitted and installed in press-fit portions (130) formed on the rear surface of the lighting body (110), as shown in FIGS. 1A to 6B.

[0088] In addition, a clamping device (600) for clamping a lighting device (100) according to one embodiment of the present invention is coupled to the lower side of the lighting body (110), thereby allowing adjustment of the irradiation angle with respect to the lighting direction of the lighting body (110). The specific configuration and function of the clamping device (600) for an electronic device according to one embodiment of the present invention will be described in more detail later.

[0089] Meanwhile, a finger guard assembly (500) may be further combined on the back surface of the lighting body (110) so as to cover all but the lower portion of the plurality of heat dissipation units (200) described above, but provided in the form of a grill so that external air (outside air) can be ventilated for heat exchange with the heat dissipation units (200).

[0090] The finger guard assembly (500) may include, as referenced in FIGS. 2A to 3B, a left finger guard panel (500L) covering the left side of a plurality of heat dissipation units (200), a right finger guard panel (500R) covering the right side of a plurality of heat dissipation units (200), a lower horizontal support bar (500DB) whose ends are horizontally connected to the lower rear portions of the left finger guard panel (500L) and the right finger guard panel (500R) and supported, and a plurality of support pipes (510) whose ends are horizontally connected to the left and right sides at a plurality of portions of the left finger guard panel (500L) and the right finger guard panel (500R).

[0091] Here, the left finger guard panel (500L) and the right finger guard panel (500R) may be provided in the form of panels including a number of heat dissipation holes (not indicated in the drawing) through which air can pass and flow.

[0092] A plurality of support pipes (510) are formed in a roughly circular pipe shape and can be screw-assembled using a plurality of pipe assembly screws (503) assembled on the outer side of the left finger guard panel (500L) and the outer side of the right finger guard panel (500R).

[0093] In addition, a plurality of support slots (507) may be formed in a plurality of support pipes (510) so that a portion of each rear end of a plurality of heat dissipation units (200) described later may be inserted and supported in contact therewith.

[0094] Meanwhile, as shown in FIGS. 2A and 3A, a lower horizontal support bar (500DB) has a downwardly inclined mounting groove (505) formed at the front end. An air vent tube (270) of the heat dissipation unit (200) described later can be accommodated in this mounting groove to protect it from the outside.

[0095] Each finger guard panel (500L, 500R) of the finger guard panel assembly (500) may be provided in the form of a panel having a number of heat dissipation holes of a somewhat small diameter to facilitate the inflow and exhaust of outside air to and from the heat dissipation unit (200) that is the object of protection inside, while preventing burn damage to an outside worker. However, in general, since the lighting device (100) according to one embodiment of the present invention is installed at a high location that is not easily accessible to the general public other than the worker, as referenced in FIGS. 2A to 3B, it may be provided with somewhat large heat dissipation holes or mesh-shaped heat dissipation holes between adjacent support pipes (510) and in the left finger guard panel (500L) and the right finger guard panel (500R) themselves so as to further increase the flow rate of outside air.

[0096] The heat dissipation unit (200) can be arranged in a vertical straight line (vertical) direction on the back surface of the lighting body (110) as shown in FIGS. 2A to 3B, and a plurality of units can be arranged at a predetermined distance apart from each other in the left and right directions of the lighting body (110).

[0097] Here, in order to install a plurality of heat dissipation units (200), the press-fitting portions (130) provided on the back surface of the lighting body (110) are also arranged in a long vertical straight (vertical) direction, and each press-fitting portion (130) can also be arranged in parallel with a predetermined distance apart in the left and right directions.

[0098] According to the press-fit portion (130) having such a configuration and the heat dissipation unit (200) installed therein, when the rising air current generated by each heat dissipation unit (200) flows directly upward on the back surface of the lighting body (110), the flow resistance thereof is minimized, thereby providing an advantage in heat dissipation design in that the circulation cycle speed of the outside air is increased.

[0099] The heat dissipation unit (200) can form a refrigerant flow space (not shown) in which refrigerant is filled inside.

[0100] Here, the heat dissipation unit (200) may include a one-side heat conduction panel (not indicated in the drawing) forming one side in the thickness direction of the refrigerant flow space, and a other-side heat conduction panel (not indicated in the drawing) forming the other side in the thickness direction of the refrigerant flow space.

[0101] A heat dissipation unit (200) of this type is formed by a method in which a heat-conducting panel on one side and a heat-conducting panel on the other side form a refrigerant flow space inside, and a metal panel member made of SUS material is joined, and a refrigerant containing water is filled in the refrigerant flow space inside, and heat transferred from an LED unit (150) can be efficiently dissipated through a phase-change gas-liquid circulation.

[0102] By employing a heat dissipation unit (200) that uses a refrigerant capable of phase change as a heat transfer medium, it is possible to achieve the heat dissipation requirement according to the dense mounting of LED elements (155) to create a somewhat narrow beam, thereby providing the advantage of greatly improving light distribution performance.

[0106] Here, the clamping device (600) may further include a housing portion (605) that covers and shields at least a portion of the steering portion (620) and the tilting portion (630).

[0107] The housing part (605) may include a housing base panel part (610) that primarily supports the steering part (620) among the steering part (620) and the tilting part (630) and mediates installation in a place requiring lighting, a front housing (605a) arranged to cover the steering part (620) and the tilting part (630) from the front, and a rear housing (605b) arranged to cover the steering part (620) and the tilting part (630) from the rear.

[0109] The rear housing (605b) can be coupled to one side of the front housing (605a) to cover or provide a coupling portion for the steering drive motor (640) and the tilting drive motor (650) among the components of the steering unit (620) and the tilting unit (630), which will be described later, and the control PCB (660), as referenced in FIGS. 8a and 8b.

[0112] Additionally, a cover screw through hole (609h-d) for screw connection to the outer end of the rear housing (605b) may be formed in the rear housing cover (607).

[0113] Meanwhile, the front housing (605a) may be formed to have an open lower portion. The opened lower portion of the front housing (605a) may be shielded by a steering panel cover (604). The steering panel cover (604) may be positioned to be spaced upward from a housing base panel portion (610) provided at the lower portion. That is, when a steering worm wheel gear portion (629) described later is coupled to a steering shaft boss (615) provided at the lower portion of the housing base panel portion (510), the steering panel cover (604) is spaced upward by a predetermined distance so that it rotates without interfering with the upper surface of the housing base panel portion (610).

[0114] Therefore, the front housing (605a), the rear housing (605b) and the steering panel cover (604) can be provided to be able to rotate left and right about the steering axis (626) described later at the upper portion of the housing base panel portion (610).

[0115] Meanwhile, as referenced in FIGS. 9a and 9b, a steering shaft boss (615) may be provided in the upper middle portion of the housing base panel portion (610) to allow the steering shaft (626) to penetrate from the bottom and be coupled to the steering base panel (621) of the steering portion (630) described later.

[0116] In addition, a steering detection dog (614) may be provided in the form of a rib with a circular arc shape at a predetermined angle around the steering shaft boss (615) of the housing base panel portion (610).

[0117] More specifically, a steering shaft boss (615) may be provided in the housing base panel portion (610) to penetrate the center of an installation hole (613) formed in a circular hole shape in the steering panel cover (604). Here, the steering detection dog (614) may be formed on the upper surface of the housing base panel portion (610), and may be provided in the form of a rib that protrudes upward through the installation hole (613) of the steering panel cover (604) so ​​as to have an arc of the angle described above among the inner circumferential surfaces of the installation hole (613) of the steering panel cover (604).

More specifically, the steer photo sensor unit (618) can be formed to extend horizontally so as to be parallel to the upper surface of the steering panel cover (604), and then extended downwardly so that the photo sensor (618a) is positioned between the steering worm wheel gear unit (629) and the steering detection dog (614).

[0120] Here, the steering photo sensor unit (618) detects the steering rotation angle by rotating in conjunction with the steering panel cover (604) when the front housing (605a) and the rear housing (605b) are rotated by the steering wheel.

[0121] In particular, the steering photo sensor unit (618) can distinguish the left and right origins when the steering of the lighting body (110) is rotated by using the photo sensor (618a). The function of this photo sensor (618a) is that even if the current position is lost due to a sudden power cut, the lighting body (110) can be restored to the initial position (origin) through the detected current position when the operating power is supplied again later.

[0122] In addition, the steering photo sensor unit (618) can additionally perform a function of compensating for the disadvantage of not being able to detect the steering angle (left and right position) in a stationary state when the initial power is applied because the tilt IMU sensor unit (638) described later is equipped as a type of acceleration sensor by including the above-described photo sensor (618a).

[0123] Meanwhile, the steering shaft (626) is provided in the form of a bolt and can be bolted to the upper steering base panel (621) by passing through the steering shaft boss (615) at the lower part of the housing base panel (510).

[0128] A plurality of worm wheel gear teeth may be formed on the outer surface of the steering worm wheel gear portion (629), and at least one stopping protrusion (629P) and a stopping groove (629H) may be formed on the lower surface of the steering worm wheel gear portion (629) so as to be fixed without rotating relative to the housing base panel portion (610).

[0129] Here, a corresponding stopping protrusion (615P) and a corresponding stopping groove (615H) can be formed on the upper surface of the steering shaft boss (615) of the housing base panel portion (610) so that the stopping protrusion (629P) and the stopping groove (629H) of the steering worm wheel gear portion (629) are mutually matched.

[0130] Accordingly, when the steering shaft (626) penetrates the steering shaft boss (615) and is fastened to the lower surface of the steering base panel (621), the stopping protrusion (629P) and the stopping groove (629H) of the steering worm wheel gear portion (629) and the stopping protrusion (615P) and the stopping groove (615H) of the steering shaft boss (615) are mutually engaged, so that the steering worm wheel gear portion (629) is fixed to the housing base panel portion (610) so that no axial rotation occurs around the steering shaft (626).

[0131] The steering worm gear portion (641) can be provided to be rotatable via a worm gear installation bracket (642) coupled to the lower portion of the steering base panel (621).

[0132] A worm gear installation bracket (642) may be coupled to a gear installation section (644) provided with an installation hole (643h-1) in which one of the two ends of the steering worm gear section (641) is rotatably supported, as shown in FIGS. 11a to 11d, and an installation hole (643h-2) in which the other of the two ends of the steering worm gear section (641) is rotatably supported.

[0133] Here, the worm gear installation bracket (642) is firmly fixed to the lower surface of the steering base panel (621) by a pair of bracket installation screws (624) that directly penetrate the steering base panel (621) in the vertical direction, and the gear installation section (644) can be fixed by a pair of gear stage fixing screws (625) that simultaneously penetrate the steering base panel (621) and the worm gear installation bracket (642) or at least penetrate the worm gear installation bracket (642).

[0134] Meanwhile, a worm gear support bearing (643) that rotatably supports both ends of the steering worm gear portion (641) may be interposed in the installation hole (643h-1) of the worm gear installation bracket (642) and the installation hole (643h-2) of the gear installation section (644), respectively.

[0135] Here, the steering worm wheel gear portion (629) is interposed on the outer surface of the steering shaft (626), and a worm wheel gear tooth (not shown) that meshes with the worm gear tooth of the steering worm gear portion (641) may be formed on a portion of the outer surface.

[0136] In addition, the steering unit (620) may further include a wheel bearing unit (628) interposed between the outer surface of the steering worm wheel gear unit (629) and a guide rib (621a) formed to protrude downward on the lower surface of the steering base panel (621), as referenced in FIGS. 11a to 11d.

[0137] The inner ring (not indicated in the drawing) of the wheel bearing part (628) is press-fitted and fixed to the remaining area of ​​the outer surface of the steering worm wheel gear part (629) where no worm wheel gear teeth are formed, and the outer ring (not indicated in the drawing) of the wheel bearing part (628) is fixed to the inner surface of the guide rib (621a) of the steering base panel (621), thereby supporting the steering rotation of the steering base panel (621) with the steering worm wheel gear part (629) as the rotation center.

The steering drive motor (640) may be provided with a motor shaft (640C) directly connected to either end of the steering worm gear unit (641). The steering drive motor (640) may be coupled to one side of the front housing (605a) via a steering motor installation bracket (645).

[0139] Here, the motor shaft (640C) of the steering drive motor (640) can be directly connected to one end of the steering worm gear portion (641) provided on the inside of the front housing (605a) by penetrating one side of the front housing (605a).

[0140] The steering drive motor (640) is configured to electrically rotate the motor shaft (640C), thereby providing the advantage of remote automatic adjustment compared to a conventional worker (or installer) manually adjusting the direction of investigation.

[0141] However, depending on the embodiment, it is not necessary to have a steering drive motor (640), and it will be natural that the worker (or installer) can adjust the direction of illumination by manually rotating the steering worm gear part (641).

[0142] The steering unit (620) configured as such is such that when a user applies power to the steering drive motor (640) and then inputs a predetermined signal, the steering drive motor (640) is driven to rotate the motor shaft (640C) in one direction or the other, and accordingly, the steering worm gear unit (641) having the worm gear teeth meshed with the worm wheel gear teeth of the fixed steering worm wheel gear unit (629) rotates along the axis, and the steering base panel (621) to which the worm gear installation bracket (642) is fixed can rotate in the left and right horizontal directions.

[0143] When the steering base panel (621) is rotated, the front housing (605a) and the rear housing (605b) that are provided to be capable of steering rotation in the left and right horizontal directions with respect to the housing base panel portion (610) are interlocked and rotated for steering, so that the irradiation direction of the lighting device (100) according to one embodiment of the present invention can be adjusted in the steering rotation direction.

[0144] FIGS. 12a and 12b are perspective views of one side and the other side showing the tilting part of the configuration of FIG. 8, and FIGS. 13a and 13b are exploded perspective views showing the tilting part of FIGS. 12a and 12b disassembled.

[0145] The tilting part (630), as referenced in FIGS. 12A to 13B, may include a tilting axis (636) provided horizontally with respect to the upper surface of the steering base panel (621), and a tilting bracket panel (631) that tilts and rotates in the up-down or front-back direction around the tilting axis (636), and to which the lower part of the lighting body (110) of the lighting device (100) according to one embodiment of the present invention is fixed.

[0146] On the upper surface of the steering base panel (621), a pair of vertical mounting panels (622) may be arranged at a predetermined distance apart in the left and right directions, and a tilting axis installation hole (622h) may be formed in each of the pair of vertical mounting panels (622) in which a tilting axis (636) is installed to be rotatably supported via a rotation support bearing part (623).

[0147] In addition, the tilting part (630) may further include a tilting worm wheel gear part (639) that is integrally formed on the outer surface of the tilting shaft (636), rotates coaxially with the center of the tilting shaft (636), is provided in an arc shape, and has worm wheel gear teeth (not shown) formed on the outer surface, as shown in FIGS. 12A to 13B, and a tilting worm gear part (651) that has worm gear teeth (not shown) formed on the outer surface to mesh with the worm wheel gear teeth of the tilting worm wheel gear part (639).

[0148] Here, the tilting worm gear portion (651) can also be fixed to the upper surface of the steering base panel (621) via the worm gear installation bracket (652), similar to the steering worm gear portion (641), as shown in FIGS. 9A and 9B. Accordingly, when the steering base panel (621) rotates, the tilting worm gear portion (651) can also rotate in conjunction with the steering.

[0149] At this time, the tilting worm gear part (651) may be arranged so as to be long in the front-back horizontal direction, but positioned between a pair of vertical mounting panels (622), and the tilting worm wheel gear part (639) may be arranged so as to be integrally formed on the outer surface of the tilting axis (636) relatively higher.

[0150] The worm gear installation bracket (652) may be provided with an installation hole (653h) in which both ends of the tilting worm gear part (651) are installed to be rotatably supported, and the tilting worm gear part (651) may be rotatably supported by a wheel bearing part (653) interposed on the outer surface of both ends of the tilting worm gear part (651) inside the installation hole (653h).

[0151] Meanwhile, on the lower surface of the tilting bracket panel (631), a pair of tilting mounting panels (632) can be vertically coupled to mediate coupling to each outer surface of a pair of vertical mounting panels (622), as shown in FIGS. 12a to 13b.

[0152] At least one panel screw penetration hole (634h-1) for screw connection of a pair of tilting mounting panels (632) may be formed vertically in the tilting bracket panel (631), and a panel screw fastening hole (634h-2) may be formed in a portion corresponding to the formation position of the panel screw penetration hole (634h-1) on the upper surface of the pair of tilting mounting panels (632).

[0153] The coupling of the tilting mounting panel (632) to the lower surface of the tilting bracket panel (631) can be completed by a screw coupling operation in which a mounting screw (633) provided in a flat-head screw shape sequentially passes through the panel screw penetration hole (634h-1) and is then fastened to the panel screw fastening hole (634h-2).

[0154] Meanwhile, both ends of the tilting axis (636) can be exposed to the outside by passing through the tilting axis installation holes (622h) of a pair of vertical mounting panels (622).

[0155] Here, at both ends of the tilting axis (636) exposed to the outside through the tilting axis installation hole (622h), at least one shaped projection (636P) forming both end surfaces and at least one shaped groove (636H) formed inwardly from both end surfaces of the tilting axis (636) can be formed.

[0156] In addition, on the inner side of each of the two sides of a pair of tilting mounting panels (632) facing the tilting axis installation hole (622h), a corresponding matching protrusion (632P) and a corresponding matching groove (632H) that are respectively matched to the matching protrusion (636P) and matching groove (636H) formed at both ends of the tilting axis (636) may be formed.

[0157] In this way, the corresponding matching protrusions (632P) and matching grooves (632H) of a pair of tilting mounting panels (632) are coupled to the matching protrusions (636P) and matching grooves (636H) formed at both ends of the tilting axis (636) so as to be matched, so that when the tilting axis (636) rotates about its axis, the pair of tilting mounting panels (632) and the tilting bracket panel (631) can tilt and rotate in the forward and backward direction (or up and down direction) based on the tilting axis (636), thereby enabling the tilting adjustment of the irradiation direction of the lighting device (100) according to one embodiment of the present invention.

[0158] Here, the tilting bracket panel (631) and a pair of tilting mounting panels (632) can be installed so as to be exposed to the outside of the front housing (605a) so as to be coupled to both ends of the tilting axis (636) through the outer tilting axis installation hole (606) formed on both sides of the upper portion of the front housing (605a) and formed to penetrate the inside and outside.

[0159] Meanwhile, the tilting unit (630) may further include a tilt IMU sensor unit (638) provided on one side of the outer circumferential surface of the tilting axis (636) to detect the tilting angle of the lighting device (100) according to one embodiment of the present invention, as referenced in FIGS. 12A to 13B.

[0160] The tilt IMU (Inertial Measurement Unit) sensor unit (638) is an inertial measurement device and is a single sensor device that includes an acceleration sensor, a gyroscope, and a geomagnetic sensor. The tilt IMU sensor unit (638) is a type of acceleration sensor and can perform the function of maintaining the origin of the lighting body (110) even when the installation environment of the lighting body (110) is tilted.

[0161] By utilizing the function of the tilt IMU sensor unit (638) as described above, the lighting body (110) can always be moved to an accurate position, and also provides the advantage of being able to move to a desired position when an aiming (need to adjust the direction of illumination) event of the lighting device (100) according to one embodiment of the present invention occurs.

[0162] Meanwhile, the tilting unit (630) may further include a tilting drive motor (650), as referenced in FIGS. 12A to 13B. The tilting drive motor (650) may be provided with a motor shaft (650C) directly connected to either end of the tilting worm gear unit (651). The tilting drive motor (650) may be coupled to one side of the front housing (605a) via a tilting motor installation bracket (655).

[0163] Here, the motor shaft (650C) of the tilting drive motor (650) can be directly connected to one end of the tilting worm gear portion (651) provided on the inside of the front housing (605a) by penetrating one side of the front housing (605a).

[0164] The tilting drive motor (650) may be configured to electrically rotate the motor shaft (650C), but it is not necessary to have the tilting drive motor (650), and it will be understood that the worker (or installer) can manually rotate the tilting worm gear unit (651).

[0165] The tilting part (630) having such a configuration is configured so that when a user inputs a predetermined signal after applying power to the tilting drive motor (650), the tilting drive motor (650) is driven to rotate the motor shaft (650C) in one direction or the other, and accordingly, the tilting worm gear part (651) having worm gear teeth meshed with the worm wheel gear teeth of the tilting worm wheel gear part (639) integrally formed on the tilting shaft (636) rotates, thereby tilting the tilting bracket panel (631) in the forward and backward direction (or up and down direction).

[0166] FIG. 14a and FIG. 14b are cross-sectional views taken along lines BB and CC of FIG. 7, FIG. 15 is a tilting operation diagram showing various angle adjustments of a lighting body using a clamping device for clamping a lighting device according to one embodiment of the present invention, and FIG. 16 is a tilting operation diagram showing various angle adjustments of a lighting body using a clamping device for clamping a lighting device according to another embodiment of the present invention.

[0167] Referring to FIG. 14a, when the steering drive motor (640) is electrically driven and the steering worm gear portion (641) directly connected to the motor shaft (640C) rotates in one direction or the other, the steering worm wheel gear portion (629) fixed to the housing base panel portion (610) rotates in the rotational direction along the outer surface thereof, thereby causing the front housing (605a) and the rear housing (605b) to rotate in the left and right horizontal directions.

[0168] At this time, the photo sensor (618a) of the steering photo sensor unit (618) is placed between the steering detection dog (614) and the steering worm wheel gear unit (629) to accurately detect the initial position regardless of a sudden power cut-off, thereby providing the advantage of ensuring the reliability of the adjustment position according to the subsequent power operation.

[0169] Meanwhile, referring to FIG. 14b, when the tilting drive motor (650) is electrically driven and the tilting worm gear part (651) directly connected to the motor shaft (650C) rotates in one direction or the other, the worm wheel gear teeth and the worm gear teeth on the outer surface of the tilting worm wheel gear part (639) integrally formed with respect to the tilting shaft (636) engage each other, thereby rotating the tilting shaft (636), thereby rotating the tilting bracket panel (631) with respect to the tilting shaft (636) to tilt and rotate the lighting body (110) in the forward and backward direction (or up and down direction).

[0170] At this time, the tilt IMU sensor unit (638) is equipped with an acceleration sensor, which provides the advantage of being able to accurately detect the tilting angle according to the tilting rotation.

[0171] In this way, according to the clamping device (600) that clamps the lighting device (100) according to one embodiment of the present invention, the initial position of the lighting body (110) can be set and controlled when the lighting device (100) is re-operated after a sudden power outage (power cut) by re-supplying power through the steer photo sensor unit (618) and the tilt IMU sensor unit (638).

[0172] When a lighting device (100) according to an embodiment of the present invention configured as described above is installed in multiple locations where lighting is required, such as a playground or a track of a playground, it can provide an advantage of being able to simultaneously control movement to set coordinates according to the address of each lighting device (100) even when controlled using the commonly used RS485 communication.

[0173] In particular, a lighting device (100) according to one embodiment of the present invention including a lighting body (110) by a tilting part (630) may be provided so that it can be tilted and rotated from -90deg forward to 10deg backward, assuming that the surface on which the LED unit (150) is installed is vertically 0deg, as shown in FIG. 15.

[0174] However, the lighting device (100) according to one embodiment of the present invention implemented in FIG. 15 is a tilting rotational configuration that exemplifies a case where the clamping device (600) is mounted on the lower side of the lighting body (110) as a general specification, and as referenced in FIG. 16, if the clamping device (600) is a reverse type located above the lighting body (110), considering the limitation according to the area where the operation control device (600) is fixed (e.g., the ceiling surface), assuming that the surface on which the LED unit (150) is installed is 0deg vertically up and down, it will be natural that the maximum tilting angle can be set to approximately 70deg backward.

[0175] In this way, the lighting device (100) according to one embodiment of the present invention provides an additional advantage of reducing the overall number of lighting devices (100) used, since the lighting device (100) can be immediately controlled in the direction of illumination through steering rotation and tilting rotation to a desired location, such as a playground or a track of a playground, by using a clamping device (600).

[0176] Meanwhile, the clamping device (600) described above is described as being applied only to the lighting device (100), but it should be noted that it is not necessarily limited to the lighting device (100).

[0177] For example, the clamping device (600) can be applied to should be broadly interpreted to include all electronic devices that require tilting or steering adjustment, such as a lighting device (100).

[0178] Therefore, a clamping device (600) for an electronic device according to one embodiment of the present invention may be defined as including a housing base panel portion (610) that fixes an electronic device requiring tilting or steering adjustment to a predetermined position, a steering base panel (621) that is steered and rotated left and right based on a steering axis (626) that is vertical to the housing base panel portion (610), and a tilting bracket panel (631) that is tilted and rotated forward and backward via a tilting axis (636) that is horizontal to the steering base panel (621) and to which a lower end of the electronic device is connected, and further including a steering photo sensor portion (618) and a tilt IMU sensor portion (638) that detect tilting rotation and steering rotation angles of an object and set and control the initial position of the electronic device when it is re-operated following a power cut-off and a re-supply of power.

[0179]
