Description

Technical Field

[0001] The present invention relates to the technical field of lighting devices, and in particular, to a lighting device. Background Art

[0002] Traditional lamps, such as ceiling lamps or wall lamps indoors, are generally directly fixed to the ceiling or wall by screws or buckles. Therefore, most of their irradiation directions are fixed, making it difficult to meet the needs of diverse scenarios. To expand the application range of lamps, some lamps are equipped with a manual adjustment function. Generally, such lamps are provided with a rotatable or adjustable joint structure between the lamp body and the fixed bracket, and the irradiation angle of the lamp body can be adjusted within a certain range.

[0003] However, although the above-mentioned manually adjustable lamps can change the irradiation direction within a certain range, the labor cost is relatively high. In places such as large shopping malls and stadiums, where there are a large number of lamps, if the angles need to be adjusted frequently, a large amount of manpower and time are required, and the adjustment efficiency is extremely low. Moreover, the manual adjustment method cannot respond to environmental changes in real time or automatically change the irradiation area, which will cause energy waste and cannot meet the lighting requirements of users. In addition, the lamp body of the existing lamps that can manually adjust the irradiation direction is generally directly rotatably arranged in the fixed bracket, and this installation method brings inconvenience to assembly and maintenance.

[0004] Therefore, there is an urgent need for a lighting device to solve the above problems. Summary of the Invention

[0047] Figure 1 The structural schematic diagram of the lighting device provided by the embodiment of the present invention is shown;Figure 2 A cross-sectional view of the lighting device provided by an embodiment of the present invention is shown. Refer to Figure 1 and Figure 2 , an embodiment of the present invention provides a lighting device. The lighting device includes a base 100, a rotating mechanism 200, a lamp 300, a radar 400, and a control module 500.

[0048] Specifically, the base 100 forms an inner cavity, and the rotating mechanism 200 is disposed in the inner cavity of the base 100. The base 100 includes a first mounting portion 110 and a second mounting portion 120 that are relatively spaced apart, and an installation space is formed between the first mounting portion 110 and the second mounting portion 120. The lamp 300 includes a lamp bracket 310 and a lamp body 320. The lamp bracket 310 is connected to the rotating mechanism 200 in the installation space and extends out of the installation space. One end of the lamp bracket 310 extending out of the installation space is connected to the lamp body 320. Through the lamp bracket 310, the connection between the lamp 300, the base 100, and the rotating mechanism 200 can be realized, and by the arrangement that the end of the lamp bracket 310 extending out of the installation space of the base 100 is connected to the lamp body 320, the problem that it is difficult to install the lamp body 320 due to insufficient operating space in the installation space can be avoided, which is beneficial to improving the assembly of the lighting device and the convenience of lamp maintenance.

[0049] More specifically, the radar 400 is disposed in the inner cavity of the base 100, can track a target, and obtain the position information of the target. The control module 500 is disposed in the inner cavity of the base 100, is communicatively connected to the radar 400, and can control the rotating mechanism 200 to act according to the position information collected by the radar 400, driving the lamp bracket 310 to rotate following the target. Through the above arrangements of the radar 400 and the control module 500, the position of the target can be tracked, and the rotating mechanism 200 can be controlled according to the position of the target to realize the adjustment of the lighting angle of the lamp body 320, without manual adjustment of the lighting angle, improving the lighting angle adjustment efficiency and the timeliness of the lighting response. In this embodiment, the radar 400 may specifically be a millimeter-wave radar sensor.

[0050] Even more specifically, the base 100 further includes a connecting portion 130. The connecting portion 130 is connected between the first mounting portion 110 and the second mounting portion 120, forming a base 100 in a portal structure. The inside of the connecting portion 130 is hollow, and the radar 400 is connected and sealed in the inner cavity of the connecting portion 130 by potting.

[0051] More specifically, the base 100 specifically includes an n-shaped base frame 180, a first side plate 150, a second side plate 160, and a top plate 170. The first side plate 150 is buckled on one side of the n-shaped base frame 180 to form a first installation part 110 with an internal cavity together with the n-shaped base frame 180. The second side plate 160 is buckled on the other side of the n-shaped base frame 180 to form a second installation part 120 with an internal cavity together with the n-shaped base frame 180. The top plate 170 is connected between the first side plate 150 and the second side plate 160 to form an internal cavity connection part 130 with the top of the n-shaped base frame 180.

[0052] Preferably, continuing to refer to Figure 2 , a side plate sealing ring 190 is clamped between the first side plate 150 and the n-shaped base frame 180, and a side plate sealing ring 190 is also clamped between the second side plate 160 and the n-shaped base frame 180. Both ends of the top plate 170 are respectively butted against the tops of the two side plate sealing rings 190. Through the above side plate sealing ring 190, the connection tightness between the first side plate 150 and the n-shaped base frame 180, between the second side plate 160 and the n-shaped base frame 180, and between the top plate 170 and the n-shaped base frame 180 can be improved, the sealing of the inner cavity of the base 100 can be realized, and the protection effect of the base 100 on the rotating mechanism 200 can be improved.

[0053] Continuing to refer to Figure 1 and Figure 2 , the lamp holder 310 includes a first extension part 311, a second extension part 312, and a fixing part 313. The first extension part 311 and the second extension part 312 are both in the shape of long strip plates and are respectively rotatably connected to one side of the first installation part 110 and the second installation part 120 opposite to each other. The first extension part 311 and the second extension part 312 are respectively fixedly connected to the fixing part 313. The fixing part 313 is also in the shape of a long strip plate and is arranged along the spacing direction of the first installation part 110 and the second installation part 120 and is fixedly connected to the lamp body 320.

[0054] Specifically, a first connection part 330 and a second connection part 340 are respectively arranged on the lamp body 320 along the spacing direction of the first installation part 110 and the second installation part 120. The first connection part 330 and the second connection part 340 extend in directions away from each other, and the first connection part 330 and the second connection part 340 are respectively connected to the fixing part 313.

[0055] More specifically, the thickness of the connection position between the first connecting portion 330 and the upper end surface of the lamp body 320 is greater than the thickness of a part of the first connecting portion 330 extending out of the upper end surface of the lamp body 320. Similarly, the thickness of the connection position between the second connecting portion 340 and the upper end surface of the lamp body 320 is greater than the thickness of a part of the second connecting portion 340 extending out of the upper end surface of the lamp body 320. Through the above settings, the connection reliability and stability between the first connecting portion 330 and the lamp body 320 can be ensured, and the connection reliability and stability between the second connecting portion 340 and the lamp body 320 can be ensured.

[0056] More specifically, referring to Figure 1 and Figure 2 , a first support rib 321 is provided on the peripheral side of the lamp body 320 corresponding to the first connecting portion 330. The first support rib 321 supports and connects to the bottom of a part of the first connecting portion 330 extending out of the lamp body 320. In this embodiment, the first support rib 321 is further connected to the upper end surface of the lamp body 320 through a first strengthening connecting member 323. The first strengthening connecting member 323 is specifically a bolt. A first countersunk hole is provided on the upper end surface of the lamp body 320. The head of the first strengthening connecting member 323 is received in the first countersunk hole, and the rod portion of the bolt is screwed into the first support rib 321.

[0057] Similarly, referring to Figure 2 , a second support rib 322 is provided on the peripheral side of the lamp body 320 corresponding to the second connecting portion 340. The second support rib 322 supports and connects to the bottom of a part of the second connecting portion 340 extending out of the lamp body 320. In this embodiment, the second support rib 322 is further connected to the upper end surface of the lamp body 320 through a second strengthening connecting member 324. The second strengthening connecting member 324 is specifically a bolt. A second countersunk hole is provided on the upper end surface of the lamp body 320. The head of the second strengthening connecting member 324 is received in the second countersunk hole, and the rod portion of the bolt is screwed into the second support rib 322.

[0058] Preferably, the two sides of the first extension part 311 in its width direction are respectively flanged to form a first reinforcing flange 315. The two sides of the second extension part 312 in its width direction are respectively flanged to form a second reinforcing flange 316. The above-mentioned first reinforcing flange 315 and second reinforcing flange 316 can respectively enhance the anti-bending ability and rigidity of the strip-shaped plate-like first extension part 311 and second extension part 312. When the lamp body 320 rotates with the rotating mechanism 200, when the first extension part 311 and the second extension part 312 bear external forces such as torque and centrifugal force, the first reinforcing flange 315 and the second reinforcing flange 316 can effectively resist deformation, ensure the stability of the rotation of the lamp bracket 310, and enable the lamp body 320 to accurately adjust the irradiation direction.

[0059] Preferably, the two sides of the fixing part 313 face away from the lamp body 320 and are flanged to form a fixing part reinforcing flange 314. The above-mentioned fixing part reinforcing flange 314 can improve the anti-bending ability of the strip-shaped plate-like fixing part 313, so that when the fixing part 313 is connected to the lamp body 320, it can effectively disperse the weight of the lamp body 320 and avoid the problem of deformation of the strip-shaped plate-like fixing part 313 due to uneven force, providing a stable and reliable installation for the lamp body 320.

[0060] Figure 3 The partial structural schematic diagram of the lighting device provided by the embodiment of the present invention is shown. Refer to Figure 2 and Figure 3 The rotating mechanism 200 includes an active driving component 210 and a driven driving component 220. The active driving component 210 is arranged in the inner cavity of the base 100 and is connected to the first extension part 311 through the side wall of the first mounting part 110 (i.e., one side of the n-shaped base frame 180). The driven driving component 220 is arranged in the inner cavity of the base 100 and is connected to the second extension part 312 through the side wall of the second mounting part 120 (i.e., the other side of the n-shaped base frame 180). By setting the active driving component 210, the first extension part 311 can be actively driven to realize the rotation of the lamp bracket 310. Through the driven driving component 220, it can cooperate with the active driving component 210 to support and drive the lamp bracket 310 on both sides of the lamp bracket 310, ensuring the smoothness and stability of the rotation of the lamp bracket 310 relative to the base 100.

[0061] Specifically, the active drive assembly 210 includes a drive member 211 and an active shaft 212. The drive member 211 is fixedly disposed in the inner cavity of the base 100 through the drive member mounting frame 140, is located in the inner cavity of the first mounting portion 110, and is transmission-connected to the active shaft 212. The active shaft 212 rotatably extends out of the side wall of the first mounting portion 110 around its own axis, and is fixedly connected to the first extension portion 311. The driven drive assembly 220 includes a driven shaft 221, which rotatably extends out of the side wall of the second mounting portion 120 around its own axis, and is fixedly connected to the second extension portion 312.

[0062] Preferably, since the smaller the diameter, the smaller the moment of inertia, the diameter of the active shaft 212 is set to be smaller than the diameter of the driven shaft 221, so as to quickly respond to the angle adjustment. And since the inner cavity of the first mounting portion 110 also needs to be provided with a transmission component to realize the transmission between the driving member 211 and the active shaft 212, the space in the inner cavity of the first mounting portion 110 is small, so the diameter of the active shaft 212 is reduced as much as possible, and installation space can also be provided for other components. The inner cavity of the second mounting portion 120 has a larger space, and increasing the diameter of the driven shaft 221 can enhance stability, further improving the stability of the lamp bracket 310.

[0063] Continue to refer to Figure 2 and Figure 3 The active drive assembly 210 further includes a first transmission wheel 213, a second transmission wheel 214 and a transmission belt 215. The first transmission wheel 213 is coaxially connected to the output shaft of the driving member 211, the second transmission wheel 214 is coaxially connected to the active rotating shaft 212, and the transmission belt 215 is wound around the first transmission wheel 213 and the second transmission wheel 214. The first transmission wheel 213, the second transmission wheel 214 and the transmission belt 215 can form a transmission to transmit the rotation of the output shaft of the driving member 211 to the active rotating shaft 212.

[0064] Specifically, the active drive assembly 210 further includes a baffle 217, which is connected to the active shaft 212 and abuts against one side of the second transmission wheel 214, and the periphery of the baffle 217 can protrude from the periphery of the second transmission wheel 214. The second transmission wheel 214 radially extends the periphery of one side of the baffle 217 to form a stopper, and the baffle 217 and the stopper can limit the transmission belt 215 to prevent it from being separated from the second transmission wheel 214, so as to ensure the reliability of transmission.

[0065] Figure 4 A cross-sectional view showing the connection between the output end of the driving member and the first transmission wheel provided by an embodiment of the present invention. Figure 4, the active driving assembly 210 further includes an axial limiting member 216, which is fixedly arranged in the output shaft of the driving member 211 and the first transmission wheel 213 in the radial direction. In this embodiment, the axial limiting member 216 may specifically be a countersunk screw, the upper end surface of which is flush with or slightly lower than the circumferential side of the first transmission wheel 213 and is fixedly connected to the output shaft of the driving member 211. The axial limiting member 216 can prevent the first transmission wheel 213 from moving axially relative to the output shaft of the driving member 211.

[0066] More specifically, referring to Figure 2 , the active driving assembly 210 further includes a first bearing 218 and a first oil seal 219. The first bearing 218 and the first oil seal 219 are arranged side by side and are both arranged in a side wall of the n-shaped base frame 180 corresponding to the first mounting portion 110. The active rotating shaft 212 rotatably passes through the first bearing 218 and the first oil seal 219 in sequence and then extends out of the first mounting portion 110. The first bearing 218 can improve the rotation smoothness of the active rotating shaft 212, and the first oil seal 219 can prevent external dust from entering the first bearing 218.

[0067] More specifically, the driven driving assembly 220 further includes a second bearing 222 and a second oil seal 223. The second bearing 222 and the second oil seal 223 are arranged side by side and are both arranged in a side wall of the n-shaped base frame 180 corresponding to the second mounting portion 120. The driven rotating shaft 221 rotatably passes through the second bearing 222 and the second oil seal 223 in sequence and then extends out of the second mounting portion 120. The second bearing 222 can improve the rotation smoothness of the driven rotating shaft 221, and the second oil seal 223 can prevent external dust from entering the second bearing 222.

[0068] More specifically, the driven rotating shaft 221 has a variable diameter structure, the diameter of its end portion is smaller, and it can extend out of the side wall of the n-shaped base frame 180. The larger diameter shaft seat portion of the driven rotating shaft 221 passes through the second bearing 222 and the second oil seal 223, and the shaft seat can abut against one side of the second extension portion 312 facing the second mounting portion 120.
