When the main panel 121, the first sub-panel 122, the second sub-panel 123 and the third sub-panel 124 are all located in the same plane, the panel assembly 12 can emit light in the same direction. When the first, second and third sub-panels 122, 123 and 124 are rotated to different positions relative to the main panel 121, the first, second and third sub-panels 122, 123 and 124 can emit light in respective planes. Thus, the illumination device 100 may be configured to emit light toward any direction at the same time, and may also be configured to emit light focused to one direction. The lighting device 100 further comprises a first lighting pattern and a second lighting pattern. In particular, when the work environment requires only local illumination, the lighting device 100 may be operated to control one of the panel assemblies 12 to light up. In the present embodiment, when the lighting device 100 is in the first lighting mode, the first sub-panel 122 is lit, and the main panel 121, the second sub-panel 123, and the third sub-panel 124 are turned off. At this time, the first sub-panel 122 may also be adjusted to output different lumen values. Specifically, the first secondary panel 122 may output a fourth gear lumen value according to environmental requirements. . When the environment illumination is required, that is, the whole area is illuminated, the illumination apparatus 100 may be operated to control all the panels to be lit up, so as to illuminate the environment where the illumination apparatus 100 is currently located in all directions, where the illumination apparatus 100 is in the second illumination mode, and the main panel 121, the first sub-panel 122, the second sub-panel 123 and the third sub-panel 124 are all lit up, that is, the illumination apparatus 100 may illuminate the area within the range of 360 °. When the lighting device 100 is in the second lighting mode, the first sub-panel 122, the second sub-panel 123, and the third sub-panel 124 are further operable to rotate about the respective axes of rotation to adjust the lighting device 100 to an optimal lighting state. The illumination device 100 also has a brightness adjustment device. The panel assemblies 12 can each be adjusted to output different values of lumens when the lighting device 100 is in different lighting modes, thereby causing the lighting device 100 to emit light of different intensities. In addition, the lighting device 100 further includes a third lighting pattern, a fourth lighting pattern, and a fifth lighting pattern. Specifically, when the lighting device 100 is in the third lighting mode, the first sub-panel 122, the second sub-panel 123, and the third sub-panel 124 are lit, and the main panel 121 is turned off, so that the lighting device 100 can illuminate the high-distance direction. When the lighting device 100 is in the fourth lighting mode, the main panel 121, the first sub-panel 122, the second sub-panel 123 and the third sub-panel 124 are all lit, and the panel assembly 12 blinks 2-3 times per second, thereby having an alarm function. When the lighting device 100 is in the fifth lighting mode, the primary panel 121, the first secondary panel 122, the second secondary panel 123 and the third secondary panel 124 are all lit, and the first secondary panel 122, the second secondary panel 123 and the third secondary panel 124 can be adjusted to output the maximum lumen value, at which time the lighting device 100 illuminates the environment with the strongest lighting state and can output a greater lumen value at the maximum power than in the second lighting mode.
The lighting device 100 includes a deployed state as shown in fig. 1 and a stowed state as shown in fig. 2. The lighting device 100 is further provided with a cover plate 14 covering at least part of the power module 13. The cover plate 14 may be extended to cover at least part of the power module 13. For clarity of explanation of the technical solution of the present invention, a front side, a rear side, a left side, a right side, an upper side and a lower side as shown in fig. 2 are also defined. When the lighting device 100 is in the storage state shown in fig. 2, the power supply unit 13 is vertically insertable into and removable from the main panel 121. In fact, the power module 13 may be inserted into or removed from the base 11, the weight of the power module 13 may be directly added to the base 11 to make the base 11 more stable for supporting other structures, the removal mechanism may be located on the back of the main panel 121, the back being the side opposite to the illumination area, and after the power module 13 is connected to the housing on the back of the main panel 121, one side of the power module 13 may contact the surface of the base or may have a gap from the surface of the base 11, and then the weight of the power module 13 may be added to the main panel 121 to make the main panel more stable as the most dominant light source. When the power supply module 13 is mounted to the main panel 121, the lighting device 100 has a first center of gravity, the first sub-panel 122, the second sub-panel 123, and the third sub-panel 124 can be rotated to any position, and the lighting device 100 does not topple. The orthographic projection of the power supply assembly 13 on the plane of the base is within the base 11 or substantially within the base 11 such that the orthographic projection of the first centre of gravity on the plane of the base 11 is in the middle of the base. When the power supply device is detached from the main panel 121, the lighting device 100 has a second center of gravity, and the first sub-panel 122, the second sub-panel 123, and the third sub-panel 124 can be rotated to any position without the lighting device 100 being overturned. The distance between the first center of gravity and the second center of gravity is 40mm or less in the front-rear direction.
Specifically, the base 11 is further provided with a control device inside, and the control device is located substantially at the rear side of the base 11 in the front-rear direction, so that when the first sub-panel 122, the second sub-panel 123, and the third sub-panel 124 are rotated to the frontmost side, the lighting device 100 can be maintained stable without overturning. It will be appreciated that the panel assembly 12 at least partially encloses the power supply assembly 13 when the lighting device 100 is in the stowed position, thereby protecting the power supply assembly from cost.
More specifically, when the illumination device 100 is in the unfolded state, its volume is larger thanIs equal to 42dm 3 67dm or less 3 (ii) a When the lighting device 100 is in the storage state, the volume thereof is 10dm or more 3 And is not more than 15dm 3 . In the present embodiment, the power of the illumination device 100 is set to 100W or more and 200W or less. Thus, the power-to-volume ratio of the illumination device 100 is set to 4.8W/dm or more 3 And is not more than 17W/dm 3 The value range at least covers different volume values when the lighting device 100 is in the storage state, but is not limited to the case where the lighting device 100 is in the storage state. Further, when the power-to-volume ratio of the illumination apparatus 100 is set to 6W/dm or more 3 And less than or equal to 10, it has the best transport, storage and use state.
The lighting device 100 further comprises a first handle 15 and a second handle 16. Wherein the first handle 15 is provided on the first sub-panel 122 and the second handle 16 is provided on the main panel 121. The first handle 15 can be manipulated to transport the lighting device 100 when the lighting device 100 is in the deployed state. The second handle 16 may be operated to transport the lighting device 100 when the lighting device 100 is in the stowed state. By providing the first handle 15 and the second handle 16, the lighting device 100 can be transported quickly in any state without interference between the handles and the lighting device 100 during transportation.
In the present embodiment, the base 11 is further provided with a positioning groove 111, and the second sub-panel 123 and the third sub-panel 124 are further provided with a positioning projection 17. When the lighting device 100 is in the storage state, the positioning protrusions 17 on the second sub-panel 123 and the third sub-panel 124 are engaged with the positioning grooves 111 on the base 11, so that the lighting device 100 can be kept in the storage state in a stable state, and the second sub-panel 123 or the third sub-panel 124 is prevented from being separated from the base when shaking. The base 11 is also made of a tough anti-falling material, so that the falling resistance of the lighting device 100 can be effectively increased. In addition, the positioning protrusion 17 is made of a rigid material and is mounted on the second sub-panel 123 and the third sub-panel 124, so that the stability of the lighting device 100 in the storage state can be effectively ensured.
As shown in fig. 3 to 5, in the present embodiment, the main panel 121, the first sub-panel 122, the second sub-panel 123, and the third sub-panel 124 are all provided with substantially the same heat dissipation structure. As for the main panel 121, it is provided to include: casing 1211 and lamp panel 1214. The casing 1211 is formed with an accommodating space 1213c, and the lamp panel 1214 is disposed in the accommodating space 1213 c. Specifically, the housing 1211 includes a first housing portion 1212 and a second housing portion 1213, and the first housing portion 1212 and the second housing portion 1213 are connected to form an accommodating space 1213 c. Lamp bulb 1214a is arranged on lamp panel 1214. In order to facilitate rapid dissipation of heat emitted by the lamp beads 1214a, the lamp panel 1214 is further made of an aluminum plate. A heat sink 1215 is further disposed on a side of the lamp panel 1214 away from the lamp bead 1214a, and the heat sink 1215 is fixedly connected to the lamp panel 1214 and can lead out heat emitted by the lamp bead 1214a on the lamp panel 1214. One side of the lamp panel 1214 close to the lamp bead 1214a is also provided with a reflective cup 1216, and the reflective cup 1216 is matched with the lamp bead 1214 a. Specifically, in order to reduce the weight of the entire panel and maintain a good heat dissipation effect, the heat sink 1215 is entirely thin, thereby effectively reducing the weight of the heat sink 1215. Further, a heat conducting member 1217 is disposed between the heat dissipating plate and the first housing portion 1212, and the heat conducting member 1217 can transfer the heat of the heat dissipating plate 1215 to the first housing 1211 and dissipate the heat through the first housing 1211.
As an implementation, the thermal conductive member 1217 is supported by a thermal conductive silicone pad, and has a thermal conductivity of 1.5W/(m · K) or more, so that heat on the heat sink 1215 can be rapidly conducted out. It is understood that the thermal conductor 1217 may also be made of a thermally conductive material such as: when the carbon nanotube composite material is used, the carbon nanotube composite material is added to the inside of the rubber-based elastomer, and the carbon nanotube composite material and the heat conductor having excellent uniformity and high thermal conductivity are realized by utilizing the high thermal conductivity of the carbon nanotube composite material. When the multilayer graphene and the derivative (graphene oxide) composite material thereof are adopted, the excellent Young modulus value, thermal stability and thermal conductivity (4000W/(m.K) -5000W/(m.K)) of the graphene are utilized, and the heat dissipation effect of the lamp body is enhanced. Can also be at the attached high heat conductivity ceramic layer in the surface of lamp plate 1214, do not establish the binder between lamp plate 1214 and the ceramic layer, combine through the atomic force between lamp plate 1214 and the ceramic layer crystalline grain, can reduce the thermal resistance between lamp plate 1214 and the ceramic layer for the heat of lamp pearl 1214a is transmitted the ceramic layer by lamp plate 1214 is quick, transmits the surface to first casing 1211. The heat conductive member 1217 may be provided with other materials having excellent heat conductive effects and thermal stability, which will not be described herein.
When the thermal conductor 1217 transfers heat to the first housing portion 1212, the first housing portion 1212 is further provided with heat dissipating ribs 1212a for quickly dissipating heat. The heat dissipating ribs 1212a are distributed around the outer surface of the first housing 1211, which effectively increases the surface area of the outer surface of the first housing portion 1212, thereby increasing heat dissipation efficiency. It is understood that the heat dissipating ribs 1212a may also be disposed on the outer surface of the second housing portion 1213, thereby further increasing the heat dissipating efficiency of the panel. In fact, through the arrangement of the heat dissipation structure, when the lamp bead 1214a inside the panel is in an operating state, the heat generated by the lamp bead 1214a can be quickly transmitted to the heat conducting member 1217 through the heat dissipation sheet 1215, and can be quickly transmitted to the first housing portion 1212 through the heat conducting member 1217, so that the heat in the accommodating space 1213c can be quickly dissipated. In this embodiment, the heat generated by the lamp beads 1214a is dissipated by heat transfer and air cooling, and the casing 1211 does not need to be provided with a separate heat dissipation air opening, thereby effectively increasing the sealing performance of the panel. In order to further increase the sealing of the panel, a sealing structure is also provided.
Specifically, the first and second housing portions 1212, 1213 are provided with a card slot arrangement. In one implementation, a groove 1212b is formed in the first housing portion 1212, a protrusion 1213a is formed in the second housing portion 1213, and when the first housing portion 1212 and the second housing portion 1213 are connected to form a whole, the protrusion 1213a is coupled with the groove 1212b to form a first sealing structure. It will be appreciated that it is also contemplated, without limitation, that first housing portion 1212 may have a protrusion formed thereon and second housing portion 1213 may have a recess formed thereon that cooperate to provide a seal. In this embodiment, the second housing portion 1213 further has an opening 1213b formed therein, and the opening 1213b allows light to be emitted. The opening 1213b is also provided with a transparent cover 1213d through which light can pass, and the transparent cover 1213d closes the opening 1213 b. In this embodiment, the transparent cover 1213d and the second housing portion 1213 are also provided with a card slot structure, which is substantially the same as the card slot structure provided on the first housing portion 1212 and the second housing portion 1213, and the description thereof is omitted here. In fact, the card slot structure provided on the first and second housing portions 1212 and 1213 and the card slot structure provided on the transparent cover 1213d and the second housing portion 1213 together constitute a first layer of sealing structure of the accommodating space 1213 c.
A sealing ring 1218 fitted with a transparent cover 1213d is also provided in the accommodating space 1213 c. Specifically, a first stopper portion 1212c that engages with the sealing ring 1218 is formed or connected to the first housing portion 1212, and a second stopper portion 1218a that engages with the first stopper portion 1212c is formed on the sealing ring 1218. When the first position-limiting portion 1212c is engaged with the second position-limiting portion 1218a, the sealing ring 1218 can be engaged with the first housing portion 1212 and at least partially fixed to the first housing portion 1212.

The hook assembly 18 is rotatably connected to the base 11 and can be rotated to a stowed position and a hanging position. When the hook assembly 18 is in the storage position, the hook is located inside the base 11 in the up-down direction, i.e. not protruding from the plane on which the lower side of the base 11 is located. When the hook assembly 18 is in the hanging position, the hook can be rotated out of the way and out of the plane of the lowermost side of the base 11. The lighting device 100 can now be suspended in a suitable position. Fig. 6 also shows a chute 112 that can connect the lighting device 100 to other tools, i.e. the lighting device 100 can also be connected to the chute 112 and fixed to other tools as well as other accessories. In addition, a nut 113 for connecting to another tool is formed or attached to the base 11, and is used to fix the lighting device 100 to another tool or other place.
As shown in fig. 7 to 9, the first sub-panel 122 is rotatably connected to the main panel 121, and is provided with a damping mechanism. Specifically, the first sub-panel 122 is connected to or formed with a pivot axis 1221, and the pivot axis 1221 is hollow inside and formed with a first pivot portion 1222. The main panel 121 is connected or formed with a first sleeve 121a and a second sleeve 121c for connecting the pivot shafts 1221. The first sleeve 121a and the second sleeve 121c are each formed with a through hole through which the first spindle portion 1222 passes. The first sleeve 121a further forms a channel 121b through which a wire can pass. In this embodiment, the wires pass out of the main panel 121 through the channel 121b of the first sleeve 121a, are distributed around the first pivot portion 1222, and are routed out of the opening 1213b of the pivot 1221, and then are routed into the first sub-panel 122. Thus, when the first sub-panel 122 rotates relative to the main panel 121, the wires do not interfere with the pivot 1221. More specifically, the lighting device 100 includes a retainer 1223 for at least partially enclosing the wire, the retainer 1223 being distributed around the second pivot portion 1224. The second spindle portion 1224 is inserted at least partially inside the first spindle portion 1222 to enclose the wire with the retainer 1223 and prevent the wire from being detached from the first spindle portion 1222. The lighting device 100 further includes a first knob 1225 for fixing the second rotating shaft portion 1224, the first knob 1225 is formed with a receiving groove for receiving at least a portion of the second rotating shaft portion 1224, and the receiving groove is engaged with or threaded with the second rotating shaft portion 1224, which will not be described herein. The first knob 1225 is also snap-fitted to the first sleeve 121a so as to be fixed to the first sleeve 121 a. The lighting device 100 further comprises a damping member 1226 detachably connected to the pivot shaft 1221, wherein the damping member 1226 can generate a damping effect between the pivot shaft 1221 and the second sleeve 121c when the first sub-panel 122 rotates relative to the main panel 121, so that the first sub-panel 122 is fixed at a predetermined position relative to the main panel 121. The lighting device 100 further comprises an adjusting piece 1228 for adjusting the damping force of the damping piece 1226, the adjusting piece 1228 is formed or connected with an adjusting rod 1229, a connecting hole 1227 matched with the adjusting rod 1229 is formed in the damping piece 1226, when the adjusting rod 1229 is inserted into the through hole, the damping force of the damping piece 1226 can be adjusted, and the first secondary panel 122 is prevented from being loosened and cannot be fixed to the preset position when rotating to the preset position relative to the main panel 121.
As shown in fig. 10, the second sub-panel 123 is also rotatably connected to the first sub-panel 122, and a damping device 19 is formed at the connecting portion, so that the second sub-panel 123 can be rotated to an arbitrary position with respect to the first sub-panel 122 and fixed at the current position. It will be appreciated that the third sub-panel 124 is also pivotally connected to the first sub-panel 122 and the damping means 19 is formed at the connection so that the third sub-panel 124 can be pivoted to any position relative to the first sub-panel 122 and fixed in the current position.
