[0041] Please refer to Figure 1 and Figure 2 , the present utility model proposes a liftable column lamp, which has a housing group 10 and a main body 20. The liftable column lamp has a retracted state as shown in Figure 1 and an extended state as shown in Figure 2 .
[0042] Please refer to Figures 3 to 6 , the housing group 10 can be disposed under the ground surface, and the housing group 10 includes a housing 11, an inner housing 12, and a top cover 13. The housing 11 is tubular and is disposed along a vertical direction.
[0043] The inner housing 12 is also tubular, and the inner housing 12 is disposed in the housing 11 along an extending direction of the housing 11. In this embodiment, the inner housing 12 and the housing 11 are spaced apart, in other words, a gap is formed between the inner housing 12 and the housing 11, so it is convenient for the user to dispose the inner housing 12, but it is not limited thereto.
[0044] The inner housing 12 has a rack 122 and a guide rail 123. The rack 122 is disposed on an inner wall surface 124 of the inner housing 12, and the rack 122 extends along the extending direction of the inner housing 12. Similarly, the guide rail 123 is disposed on the inner wall surface 124 of the inner housing 12, and the guide rail 123 extends along the extending direction of the inner housing 12.
[0045] Specifically, in this embodiment, the cross-section of the inner housing 12 is polygonal and has a plurality of inner wall surfaces 124, which are connected to each other and jointly surround the interior of the inner housing 12, and the rack 122 and the guide rail 123 are respectively formed on one of the inner wall surfaces 124. In addition, the inner housing 12 can include a plurality of guide rails 123, which are respectively formed on a plurality of different inner wall surfaces 124, but it is not limited thereto.
[0046] In this embodiment, the guide rail 123 has a groove 1231, which extends along the extending direction of the inner housing 12, but it is not limited thereto, and the form of the guide rail 123 can be adjusted according to requirements.
[0047] Please refer toFigures 3 to 5 and Figure 7 The top cover 13 is disposed at a top end 111 of the outer shell 11 and a top end 121 of the inner shell 12; specifically, the top cover 13 is sealed to the top end 111 of the outer shell 11 and the top end 121 of the inner shell 12 to prevent water or dust from falling into the gap between the inner shell 12 and the outer shell 11. In this embodiment, the top cover 13 is detachably disposed on the outer shell 11 and the inner shell 12, whereby it is easy to install or disassemble the present utility model.
[0048] The top cover 13 has a top surface 131, a bottom surface 132, a top opening 133, a scraping member 134, and a roller 135. The top surface 131 and the bottom surface 132 are two opposite surfaces of the top cover 13. In this embodiment, the top surface 131 faces upward and is flush with the ground surface.
[0049] The top opening 133 is formed through the top surface 131 and the bottom surface 132, and thereby the exterior and the interior of the inner shell 12 are spatially connected to each other. In this embodiment, the top opening 133 is a rectangle with rounded corners, but is not limited thereto.
[0050] The scraping member 134 surrounds the top opening 133 and protrudes inward from the edge of the top opening 133. In this embodiment, the scraping member 134 is disposed between the top surface 131 and the bottom surface 132, but in other embodiments, the scraping member 134 can also be disposed on the top surface 131 or the bottom surface 132. The scraping member 134 has elasticity and contacts the main body 20, thereby preventing water or dust from entering the inner shell 12 through the top opening 133.
[0051] The roller 135 is rotatably disposed on the bottom surface 132 of the top cover 13 and is located at the position of the top opening 133; specifically, the roller 135 is cylindrical and is disposed along the edge of the top opening 133. The roller 135 contacts the main body 20 and thereby makes the movement of the main body 20 smoother.
[0052] Please refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 , the main body 20 is movably disposed within the housing group 10.
[0053] Please refer to Figures 3 to 6 and Figure 13 , the main body 20 has a moving component 21, a light source component 22, and a power module 23.
[0054] The moving component 21 is disposed inside the inner shell 12, and the moving component 21 can move relative to the inner shell 12 along the extending direction of the inner shell 12. The moving component 21 has a housing member 211, a motor 212, a gear 213, and a guiding member 214. The motor 212 is disposed on the housing member 211, and the gear 213 is rotatably disposed on the motor 212. The gear 213 is located outside the housing member 211 and meshes with the rack 122, so that the motor 212 can drive the gear 213 to move along the rack 122.
[0055] Please refer to Figure 3 、 Figure 4 、 Figure 6 、and Figure 8 , the guiding member 214 is disposed at a bottom of the housing member 211 and protrudes radially to contact the guide rail 123, whereby the guiding member 214 can move along the guide rail 123 to prevent the main body 20 from rotating relative to the inner shell 12 during movement.
[0056] Specifically, the guiding member 214 has a wheel 2141 which is disposed in the groove 1231 of the guide rail 123. The wheel 2141 can roll in the groove 1231, and a width of the wheel 2141 is equal to a width of the groove 1231, thereby reducing the influence of friction when the guiding member 214 and the guide rail 123 move relative to each other, so that the main body 20 can move smoothly. In other embodiments, the forms of the guiding member 214 and the guide rail 123 can be adjusted according to requirements.
[0057] Please refer to Figures 4 to 7 and Figure 13 , the light source assembly 22 is disposed on the moving component 21, so that the light source assembly 22 can move with the moving component 21. The light source assembly 22 is disposed inside the inner shell 12 and can move outside the inner shell 12 through the top opening 133.
[0058] The light source assembly 22 has a lamp housing 221, a driving module 222, a light emitting unit 223, and a connecting rod 224. The lamp housing 221 is connected to the moving component 21, and please refer to Figure 5 , the lamp housing 221 has an upper surface 2211 which faces upward, and when the liftable column lamp of this embodiment is in the retracted state, the upper surface 2211 is flush with the top surface 131 of the top cover 13.
[0059] Please refer to Figure 4 、 Figure 6 、and Figure 7 , in this embodiment, the shape of the lamp housing 221 is a cuboid, and the scraping member 134 contacts an outer wall surface of the lamp housing 221. In addition, the roller 135 of the top cover 13 also contacts the outer wall surface of the lamp housing 221 so that the main body 20 can move smoothly.
[0060] Please refer to Figure 4 、 Figure 9 、Figure 10 and Figure 13 The driving module 222 is disposed on the lamp housing 221, and the light-emitting unit 223 is pivotally disposed on the lamp housing 221. The connecting rod 224 is connected to the driving module 222 and the light-emitting unit 223, so that the driving module 222 can drive the light-emitting unit 223 to pivot.
[0061] In this embodiment, the light-emitting unit 223 can pivot relative to a horizontal axis, so that the light-emitting unit 223 can change the irradiation angle up and down. Please refer to Figure 9 and Figure 10 , the driving module 222 pulls the connecting rod 224 downward, and the connecting rod 224 pulls the light-emitting unit 223, so that the light-emitting unit 223 irradiates upward, and vice versa. In addition, the light source assembly 22 can have two light-emitting units 223 and two connecting rods 224. One connecting rod 224 connects one of the light-emitting units 223 and the driving module 222, and the other connecting rod 2240 connects the two light-emitting units 223, whereby the two light-emitting units 223 can move synchronously, but not limited thereto.
[0062] In addition, please refer to Figure 9 , the light source assembly 22 can further have a limiting block 225, which is fixed on the lamp housing 221, thereby restricting a movement range of the connecting rod 224. Specifically, the connecting rod 224 can further have a limiting groove 2241, and when the driving module 222 continuously drives the connecting rod 224 in the same direction, the limiting block 225 will be engaged with the limiting groove 2241, so that the movement range of the connecting rod 224 and the irradiation angle range of the light-emitting unit 223 are restricted, but not limited thereto. The light source assembly 22 may also not have the limiting block 225.
[0063] Please refer to Figure 4 , Figure 11 and Figure 13 , the power module 23 is electrically connected to the moving component 21 and the light source assembly 22, and the power module 23 can control the movement of the moving component 21, control the light-emitting unit 223 to emit light, and control the driving module 222 to change the irradiation angle of the light-emitting unit 223 through a control circuit 231. The power module 23 also serves as a power supply.
[0064] In this embodiment, the power module 23 is disposed on the housing 211 of the moving component 21, but not limited thereto. In addition, the power module 23 can slowly retract into the main body 20 after the present utility model is turned off. Specifically, please refer to Figure 4 , Figure 11 and Figure 12, the power module 23 can have a power storage device 232, which includes a capacitor 2321 with a large capacitance value. The capacitor 2321 is electrically connected to the moving component 21 of the main body 20. The capacitor 2321 of the power storage device 232 can be charged when the lift column light is turned on, and once the lift column light is turned off, the power storage device 232 can still supply power to the motor 212 to slowly move the main body 20 downward for retraction.
[0065] Please refer to Figures 4 to 6 , when the lift column light extends, the motor 212 drives the gear 213 to rotate, and the moving component 21 moves upward along the rack 122 of the inner shell 12. The guide member 214 rolls in the guide rail 123, and the roller 135 of the top cover 13 rolls and contacts the lamp housing 221 of the light source assembly 22.
[0066] On the other hand, when the lift column light is turned off, the power storage device 232 discharges to supply power to the motor 212, so that the gear 213 can rotate relative to the rack 122 at a certain speed, and the main body 20 retracts downward slowly instead of falling freely.
[0067] When not in use, the lift column light can be retracted to the retracted state. Since the housing group 10 is arranged underground, and the top surface 131 of the top cover 13 and the upper surface 2211 of the lamp housing 221 are flush with the ground surface, the lift column light of the present invention will not affect the movement of vehicles or devices on the ground.
[0068] Since the housing group 10 can be divided into an outer housing 11 and an inner housing 12, and the top cover 13 can be detached from the outer housing 11 and the inner housing 12, the user can easily install or disassemble the lift column light of the present invention. For example, when the user wants to perform maintenance on the main body 20, the user can leave the outer housing 11 underground and take out the inner housing 11 and the main body 20 after removing the top cover 13.
[0069] In addition, since part of the lift column light is installed underground, it is important to prevent water, dust, or other small objects from falling into the lift column light. As a solution, the scraping member 134 of the top cover 13 fills the gap between the top cover 13 and the light source assembly 22, and the top cover 13 seals the top ends 111 of the outer housing 11 and 121 of the inner housing 12 to prevent water or dust from falling into the inner housing 12, thus reducing the risk of damage.
[0070] When the main body 20 is moving, the guide rail 123 and the guide member 214 can prevent the main body 20 from rotating, and the wheel 2141 of the guide member 214 and the roller 135 of the top cover 13 can help the main body 20 move smoothly, so that the wear between the parts of the lift column light and the maintenance frequency can be reduced.
[0071] In addition, the irradiation angle of the light-emitting unit 223 can be changed by the driving module 222 and the connecting rod 224, so that the light-irradiating range of the liftable column lamp of the present utility model can be adjusted according to the venue or weather.
[0072] In addition, when the main body 20 is retracted by the power pre-stored in the power storage device 232, the liftable column lamp can be directly turned off without having to separately cut off the power supplies of the motor 212, the light-emitting unit 223, and the driving module 222. Therefore, the control design of the liftable column lamp of the present utility model can be simplified.
[0073] The above are only the preferred embodiments of the present utility model and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to form equivalent embodiments with equivalent changes without departing from the technical solution of the present utility model. However, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model still fall within the scope of the technical solution of the present utility model.
