Description

Technical Field

[0001] This utility model relates to a light source lifting control device and a lamp, belonging to the field of lighting technology. Background Technology

[0002] Most of the lifting lights commonly found on the market are manually operated, with very few capable of automatic lifting. Furthermore, these automatic lifting lights often suffer from excessively large motors, resulting in an overall bulky light that is inconvenient to install and transport.

[0003] Furthermore, the suspension wires used for raising and lowering most lighting fixtures cannot simultaneously perform the functions of raising and lowering and supplying power. That is, raising and lowering lighting fixtures requires the use of suspension wires to raise and lower the lamp head and the use of conductive wires to supply power to the lamp head. This makes it easy for the conductive wires to become tangled during the lamp head raising and lowering process, and even worse, the conductive wires may come loose during the lamp head raising and lowering process, affecting the normal use of the lighting fixture.

[0004] In view of this, it is indeed necessary to improve the existing lifting light fixtures to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a light source lifting control device that can realize automatic lifting and synchronous power supply of the light source, and solve the problem of power supply wire winding during the lifting process of the light source.

[0023] Optionally, the ceiling control box is equipped with a motion sensor, which is configured to connect to the actuator to sense differences in the force applied to the actuator.

[0024] Optionally, the light source assembly includes a mounting component, a light source board mounted on the mounting component, and a lampshade that is fastened to the mounting component. Wires pass through the mounting component and are electrically connected to the light source board, and the lampshade covers the outside of the light source board.

[0025] The beneficial effects of this utility model are as follows: The light source lifting control device of this utility model houses the connecting seat portion of the electrical connector within the transmission component, and the wire electrically connected to the connecting seat passes through the transmission component to connect the light source assembly.

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] Please see Figures 1-3 As shown, this utility model discloses a lamp 100, including a ceiling control box 20, a light source lifting control device 30, a light source assembly 40, and a light-transmitting cover 50. The ceiling control box 20 is installed on a fixed wall and connected to a power source. The light source lifting control device 30 is connected to the ceiling control box 20 and can operate under the control of the ceiling control box 20. The light source assembly 40 is connected to the light source lifting control device 30 and can rise or fall under the action of the light source lifting control device 30. The light-transmitting cover 50 is placed on the outside of the light source lifting control device 30 and the light source assembly 40, and the light source assembly 40 can rise or fall within the light-transmitting cover 50 under the drive of the light source lifting control device 30. The lamp 100 of this utility model utilizes the light source lifting control device 30 to achieve automatic lifting and lowering of the light source assembly 40 in a small space and can synchronously power the light source assembly 40, thus avoiding the problem of power supply wire tangling during the light source lifting process.

[0045] like Figures 4-7As shown, the light source lifting control device 30 includes a housing 31, a limiting member 32, a driving member 33, a transmission member 34, and an electrical connector 35 assembled within the housing 31. The driving member 33, transmission member 34, and electrical connector 35 are positioned between the limiting member 32 and the housing 31. In other words, in this embodiment, the limiting member 32 limits and fixes the driving member 33, transmission member 34, and electrical connector 35 within the housing 31. The driving member 33 provides driving force. The transmission member 34 is connected to the driving member 33 and can rotate under the drive of the driving member 33. The electrical connector 35 is assembled at the end of the transmission member 34 away from the driving member 33, and is electrically connected to the light source assembly 40. Under the driving action of the driving member 33, the electrical connector 35 can drive the light source assembly 40 to rise or fall.

[0046] Specifically, the driving component 33 includes a motor 331 and an output gear 332 connected to the output shaft of the motor 331. The motor 331 is preferably a small DC geared motor with a self-locking function, and the motor 331 drives the output gear 332 to rotate. The transmission component 34 includes a wound shaft 341 and an input gear 342 connected to one end of the wound shaft 341 and meshing with the output gear 332. The output gear 332 can drive the wound shaft 341 to rotate via the input gear 342. In this embodiment, the wound shaft 341 is arranged in a ring shape. The transmission component 34 also includes a rotating body 343 connected to both the input gear 342 and the wound shaft 341. The input gear 342 is connected to the input shaft 3431 of the rotating body 343 to drive the rotating body 343 to rotate. One end of the wound shaft 341 is sleeved on the rotating body 343 and is fixedly connected to the rotating body 343 by screws or other fasteners. In other words, the rotating body 343 is partially housed within the winding shaft 341, thereby achieving stable rotation of the winding shaft 341 through transmission.

[0047] like Figure 6 As shown, the electrical connector 35 includes a wire 351 and a connector 352 electrically connected to the wire 351. The connector 352 is partially housed in the transmission member 34 and connected to one end of the wire 351. The other end of the wire 351 passes through the transmission member 34 and connects to the light source assembly 40. In this embodiment, the winding shaft 341 is provided with a wire groove 3412 and a through hole 3411 within the wire groove 3412. The wire 351 passes through the through hole 3411 and is wound or unwound within the wire groove 3412. This arrangement prevents the wire 351 from slipping off the winding shaft 341 during winding or unwinding. The connector 352 includes a plug 3521 and a socket 3522 that engage with each other. One of the plug 3521 and the socket 3522 is electrically connected to the wire 351, and the plug 3521 and the socket 3522 are rotatably disposed relative to each other.

[0048] Specifically, a plug 3521 or socket 3522, electrically connected to the wire 351, is fixedly connected to the winding shaft 341 and rotates with the winding shaft 341, thereby driving the wire 351 to be wound or unwound within the wire groove 3412. In this embodiment, the plug 3521 is partially housed within the winding shaft 341 and electrically connected to the wire 351. A washer 3523 is fitted onto the plug 3521, and the winding shaft 341 is fixedly connected to the washer 3523 by screws or other fasteners, thereby achieving a fixed connection between the winding shaft 341 and the plug 3521. In other optional embodiments, a socket 3522 can also be fixedly connected to the winding shaft 341 and electrically connected to the wire 351, as long as the wire 351 can be energized; there are no restrictions on this.

[0049] Preferably, the washer 3523 partially covers the plug 3521 inside the winding shaft 341, and the wire 351 is arranged inside the winding shaft 341. Based on the drive of the drive member 33, the rotation of the transmission member 34 causes the wire 351 to be wound or unwound relative to the transmission member 34, which can control the rise or fall of the light source assembly 40.

[0050] In this embodiment, multiple wires 351 are provided, and multiple through holes 3411 are correspondingly provided and aligned at intervals along the axial direction of the winding shaft 341. Optionally, the rotating body 343 is provided with a clearance groove 3432 for arranging the wires 351, and some of the wires 351 are routed in the clearance groove 3432 and pass through the through holes 3411. In this way, the rotating body 343 is housed in the winding shaft 341, which improves rotational stability without affecting the arrangement of the wires 351 inside the winding shaft 341; it also avoids the problem of the light source assembly 40 being affected by the close distance between multiple wires 351 on the winding shaft 341 when multiple wires 351 are wound or unwound. Preferably, multiple wire grooves 3412 are provided and spaced at intervals along the axial direction of the winding shaft 341. Each wire groove 3412 has a corresponding through hole 3411, allowing each wire 351 to be wound or unwound within the corresponding wire groove 3412, avoiding mutual interference. Of course, in other optional embodiments, there may be only one wire groove 3412, in which case multiple through holes 3411 are spaced apart and aligned within one wire groove 3412.

[0051] Combination Figure 5As shown, preferably, the motor 331, the input shaft 3431 of the rotating body 343, and the socket 3522 are all supported on the housing 31. The limiting member 32 is fixedly connected to the housing 31 by fasteners such as screws, and the motor 331, the rotating body 343, and the socket 3522 are limited and fixed between the housing 31 and the limiting member 32. The housing 31 is also provided with a plurality of through holes 311 for wires 351 to pass through and connect to the light source assembly 40. The plurality of through holes 311 are preferably arranged in a ring. Of course, in other optional embodiments, the plurality of through holes 311 can also be arranged in a straight line, which is not limited. In this embodiment, there are three wires 351, and the three through holes 311 on the housing 31 form a triangle, so that the force on each wire 351 is balanced when connected to the light source assembly 40.

[0052] like Figure 8 As shown, the light source assembly 40 includes a mounting member 41, a light source plate 42 mounted on the mounting member 41, and a lampshade 43 that is fastened to the mounting member 41. A wire 351 passes through the mounting member 41 and is electrically connected to the light source plate 42, and the lampshade 43 covers the outside of the light source plate 42. The mounting member 41 is I-shaped and includes a first mounting plate 411, a second mounting plate 412, and a snap-fit ​​post 413 connecting the first mounting plate 411 and the second mounting plate 412. The light source plate 42 is mounted on the second mounting plate 412, and the wire 351 passes through the first mounting plate 411 and the second mounting plate 412 and is connected to the light source plate 42. The lampshade 43 is preferably a silicone cover and is spherical, and the lampshade 43 is snapped onto the snap-fit ​​post 413 for adjusting the light.

[0053] The light source lifting control device 30, through the wire 351, not only suspends the light source assembly 40 but also supplies power to the light source assembly 40 to achieve lighting. This arrangement not only reduces the need for redundant suspension or power supply wires and solves the wiring tangling problem that may occur during the lifting of the light source assembly 40, but also simplifies the structural layout of the light source lifting control device 30.

[0054] like Figure 4 As shown, the light source lifting control device 30 also includes a control plate 36 mounted on the side of the limiting member 32 facing away from the driving member 33. The control plate 36 is electrically connected to the connecting seat 352 and the driving member 33, providing power to the connecting seat 352 and the driving member 33 and controlling the operation of the driving member 33. A position switch 37 electrically connected to the control plate 36 is provided on the side of the housing 31 facing the light source assembly 40. The position switch 37 is configured to be triggered when it comes into contact with the light source assembly 40, causing the driving member 33 to stop operating. The position switch 37 can also detect and provide feedback on the initial position of the light source assembly 40.

[0055] Preferably, the control board 36 includes a step-down board 361 and a driver 362 electrically connected. The driver 362 is electrically connected to the drive component 33 and is used to control the operation of the drive component 33. The step-down board 361 is connected to the power supply in the ceiling control box 20 to regulate the voltage to meet the usage requirements of the drive component 33 and the light source assembly 40. A position switch 37 is connected to the driver 362. The position switch 37 can cause the driver 362 to control the drive component 33 to stop operating when the light source assembly 40 rises to the top, thus avoiding damage to the light source assembly 40 and the light source lifting control device 30 due to excessive winding of the wire 351.

[0056] like Figure 4 and Figure 7 As shown, optionally, the housing 31 is hemispherical. The position switch 37 is located at the arc-shaped bottom of the housing 31, and the opening 312 of the housing 31 faces the ceiling control box 20. A connecting plate 38 for connecting the ceiling control box 20 and the light-transmitting cover 50 is provided at the opening 312. Specifically, the connecting plate 38 is fixedly connected to the housing 31 by fasteners such as screws, and a closed space is formed between the connecting plate 38 and the housing 31 to accommodate the drive component 33, the limiting component 32, etc.

[0057] In this embodiment, the light source lifting control device 30 is suspended below the ceiling control box 20. A connecting plate 38 connects the light source lifting control device 30 and the ceiling control box 20. A connecting hole 381 communicating with the enclosed space is provided at the center of the connecting plate 38. The light source lifting control device 30 and the ceiling control box 20 are connected by a connecting rope 60. One end of the connecting rope 60 passes through the connecting hole 381 and is fixedly connected to the connecting plate 38, while the other end extends into the ceiling control box 20 and is fixedly connected.

[0058] The connecting plate 38 is preferably disc-shaped and protrudes gradually from the edge towards the center toward the ceiling control box 20. The light-transmitting cover 50 is connected and fixed to the connecting plate 38. The light-transmitting cover 50 is spherical and preferably a glass cover. The top of the light-transmitting cover 50 has a mounting opening (not shown), and the connecting plate 38 is snapped into the mounting opening to achieve the installation and fixation of the light-transmitting cover 50. The light source lifting control device 30 and the light source assembly 40 are both integrated inside the light-transmitting cover 50. The light source lifting control device 30 can be used to lift and lower the light source assembly 40 inside the lamp 100 within a small space.

[0059] like Figure 7As shown, a protruding connecting platform 313 is provided on the inner peripheral wall of the housing 31 near the opening 312. The connecting platform 313 has an insertion hole 3131 for the pin 39 to pass through the connecting plate 38 and be inserted into the insertion hole 3131. A support plate 391, rotatable around the pin 39, is fitted onto the pin 39. The support plate 391 is located between the connecting platform 313 and the connecting plate 38. The support plate 391 can rotate towards or away from the connecting platform 313, such that when rotating towards the connecting platform 313, the support plate 391 can be accommodated on the connecting platform 313 and located within the housing 31. When rotating away from the connecting platform 313, the support plate 391 is exposed and protrudes from the outer surface of the housing 31.

[0060] Preferably, a groove 314 is provided on the housing 31 corresponding to the connecting platform 313, so that the support plate 391 can rotate freely to be housed inside the housing 31 or exposed outside the housing 31. Multiple sets of connecting platforms 313 and support plates 391 are provided. When the support plate 391 is exposed outside the housing 31, it can abut against the inner wall surface of the light-transmitting cover 50 to enhance the connection stability between the light-transmitting cover 50 and the connecting plate 38.

[0061] like Figure 1 As shown, in this embodiment, the raising and lowering of the light source assembly 40 is mainly controlled by commands issued by the ceiling control box 20. The ceiling control box 20 contains a motion sensor (not shown). The motion sensor is configured to connect to the actuator 70 to sense differences in the force applied to the actuator 70, and based on these differences, the ceiling control box 20 sends commands to the driver 362.

[0062] The following detailed description uses a motion sensor preferably a gravity sensor and an actuator 70 preferably a gravity ball as an example. The gravity ball is connected to the gravity sensor via a suspension wire 71. A pulley assembly 80 can also be provided on the fixed wall for the suspension wire 71 to pass through, so that the gravity ball is suspended on one side of the ceiling control box 20. By pulling the gravity ball for a long time, the gravity sensor will sense an increase in the force on the gravity ball, and the ceiling control box 20 will send a command to the driver 362 to control the drive component 33 to drive the light source assembly 40 to descend. Alternatively, by lifting the gravity ball upwards, the gravity sensor will sense a decrease in the force on the gravity ball, and the ceiling control box 20 will send a command to the driver 362 to control the drive component 33 to drive the light source assembly 40 to rise, realizing human-computer interaction. Of course, in other optional embodiments, the ceiling control box 20 can also be controlled via an APP, and there is no limitation on this.

[0063] Optionally, in this embodiment, as the light source assembly 40 rises or falls within the light-transmitting cover 50, the color temperature of the light source plate 42 may also change accordingly. For example, as the light source assembly 40 falls, the color temperature of the light source plate 42 gradually decreases, and as the light source assembly 40 rises, the color temperature of the light source plate 42 gradually increases.

[0064] In summary, the light source lifting control device 30 of this utility model assembles an electrical connector 35 at the end of the transmission member 34 away from the driving member 33, and houses the connecting seat 352 of the electrical connector 35 within the transmission member 34. A wire 351, electrically connected to the connecting seat 352, passes through a through hole 3411 on the transmission member 34 and is electrically connected to the light source assembly 40. Based on the driving member 33, the rotation of the transmission member 34 causes the wire 351 to be wound or unwound relative to the transmission member 34, thereby controlling the rise or fall of the light source assembly 40, achieving automatic lifting. Compared to the prior art, the light source lifting control device 30 of this utility model can achieve automatic lifting and synchronous power supply of the light source using the wire, and can also avoid wire tangling during the lifting process.

[0065] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
