Description

Technical Field

[0001] This application relates to the field of lighting equipment technology, and in particular to a low-profile studio embedded lighting fixture lifting, flipping and dimming device. Background Technology

[0002] In low-ceilinged studios, space is often limited, and traditional lighting installation methods can take up a significant amount of space, affecting the studio layout and the installation of other equipment. While recessed lighting saves some space, most existing recessed lights lack height and tilting capabilities, making it difficult to adjust the angle and height of the light according to the needs of different broadcast scenarios. For example, some small interview programs may only require lower angle and closer lighting, while large-scale performance programs may require higher and farther lighting. Existing recessed lighting cannot adequately meet these diverse needs. Therefore, research on recessed lighting is necessary.

[0003] In the prior art, Chinese patent CN211203805U discloses an embedded electric flip-up conference light, including a mounting housing, a light source assembly embedded in the mounting housing, a mounting groove on the front side of the mounting housing with a control device at the groove opening, a heat sink on the rear side of the mounting housing with several heat dissipation holes, a rotating shaft connected to the light source assembly, and the light source assembly connected to the mounting housing via the rotating shaft, with a drive device connected to one end of the rotating shaft. By driving the rotating shaft to rotate, the conference light can be rotated at multiple angles, thereby meeting the requirements for different lighting angles in different situations.

[0004] However, the aforementioned existing technologies only consider the rotation of the lamps and cannot realize the raising, lowering and dimming of the lamps, making it difficult to meet the diverse adjustment needs of low-ceiling studios for embedded lamps. Utility Model Content

[0010] One side of the lamp is hinged to one side of the lower platform via the hinge, and the flipping motor is engaged with the hinge.

[0011] The control unit is electrically connected to the lamp via a dimming chip.

[0015] In one possible implementation, the scissor lift support includes at least two sets in the front-to-back direction, and each set of scissor lift supports includes at least one scissor structure in the vertical direction.

[0016] In one possible implementation, a central cross axis is provided between the central intersection points of the scissor structures at the same height at the front and rear, and an edge cross axis is provided between the edge intersection points.

[0017] In one possible implementation, the electric actuator passes laterally across two edge cross axes at the same height to bring the two edge cross axes closer together or further apart.

[0018] In one possible implementation, the hinge axis of the hinge is connected to the flip motor axis of the flip motor via a gear set.

[0019] In one possible implementation, the number of teeth on the gear corresponding to the hinge shaft is greater than the number of teeth on the gear corresponding to the flip motor shaft.

[0020] In one possible implementation, the control unit is also electrically connected to a light intensity sensor.

[0021] In one possible implementation, the flipping motor is a self-locking motor.

[0023] By incorporating a lifting mechanism, a tilting mechanism, and a control unit, the lighting fixtures achieve lifting, tilting, and dimming functions, meeting the diverse adjustment needs of low-ceiling studios for recessed lighting fixtures. Specifically, the lifting function is achieved through an upper platform, upper mounting bracket, lower platform, lower mounting bracket, scissor-type lifting bracket, and electric push rod; the tilting function is achieved through hinges and a tilting motor; and the dimming function is achieved through a control unit and a dimming chip.

Detailed Implementation

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] like Figs. 1 to 3 As shown in the figure, this application embodiment provides a low-profile studio embedded lighting fixture lifting, flipping and dimming device, including: lifting mechanism, flipping mechanism 21, lighting fixture 22 and control unit.

[0036] The lifting mechanism includes: an upper platform 11, an upper mounting frame 12, a lower platform 13, a lower mounting frame 14, a scissor-type lifting bracket 15, and an electric push rod 16.

[0037] The flipping mechanism 21 includes a hinge 211 and a flipping motor 212.

[0038] The upper mounting bracket 12 is fixedly installed on the lower side of the upper platform 11, the lower mounting bracket 14 is fixedly installed on the upper side of the lower platform 13, the scissor lift bracket 15 is hinged between the upper mounting bracket 12 and the lower mounting bracket 14, and the electric push rod 16 is horizontally installed on the scissor lift bracket 15.

[0039] One side of the lamp 22 is hinged to one side of the lower platform 13 via the hinge 211, and the flip motor 212 is engaged with the hinge 211.

[0040] The control unit is electrically connected to the lamp 22 via a dimming chip.

[0041] The control unit is also electrically connected to the electric push rod 16 and the flip motor 212, respectively.

[0042] Specifically, in this embodiment, the upper platform 11 is fixedly installed in a pre-set mounting slot at the top of the low studio. The electric push rod 16 is controlled by the control unit to shorten or lengthen the scissor lift bracket 15 in the vertical direction, thereby raising or lowering the lamp 22. The tilting motor 212 is controlled by the control unit to adjust the angle between the lamp 22 and the lower platform 13 between 0° and 90°, thereby tilting the lamp 22. The brightness of the lamp 22 is adjusted by controlling the current of the dimming chip.

[0043] For example, the upper mounting bracket 12 is provided with an upper sliding groove 121, the top left end of the scissor lifting bracket 15 is slidably hinged to the upper sliding groove 121 via an upper slider 122, and the top right end is fixedly hinged to the upper mounting bracket 12.

[0044] The lower mounting bracket 14 is provided with a sliding groove 141. The bottom left end of the scissor lift bracket 15 is slidably hinged to the sliding groove 141 via a sliding block 142, and the bottom right end is fixedly hinged to the lower mounting bracket 14.

[0045] Specifically, in this embodiment, when the upper slider 122 is at the upper sliding groove 121 near the top right end of the scissor lifting bracket 15, the lower slider 142 is at the lower sliding groove 141 near the bottom left end of the scissor lifting bracket 15. At this time, the scissor lifting bracket 15 has the maximum length in the vertical direction, that is, the lamp 22 has descended to its limit.

[0046] When the upper slider 122 is at the top right end of the upper slide groove 121 away from the top of the scissor lifting bracket 15, the lower slider 142 is at the bottom left end of the lower slide groove 141 away from the bottom of the scissor lifting bracket 15. At this time, the vertical length of the scissor lifting bracket 15 is the minimum, that is, the lamp 22 rises to the limit.

[0047] For example, the scissor lift bracket 15 includes at least two sets in the front-to-back direction, and each set of scissor lift brackets 15 includes at least one scissor structure in the vertical direction.

[0048] Specifically, in this embodiment, the scissor lift bracket 15 is arranged in two sets in the front-to-back direction, and each set of scissor lift bracket 15 includes two scissor structures in the vertical direction. In other possible embodiments, the number of sets of scissor lift bracket 15 in the front-to-back direction and the number of scissor structures in each set of scissor lift bracket 15 in the vertical direction can be adjusted. The larger the number of sets of scissor lift bracket 15 in the front-to-back direction, the higher its stability; the larger the number of scissor structures in each set of scissor lift bracket 15 in the vertical direction, the larger its lifting range.

[0049] For example, a central cross axis 151 is provided between the central intersection points of the scissor structure at the same height at the front and rear, and an edge cross axis 152 is provided between the edge intersection points.

[0050] Specifically, in this embodiment, the central cross shaft 151 is rotatably connected to the scissor arm of the corresponding scissor structure, and the edge cross shaft 152 is rotatably connected to the scissor arm of the corresponding scissor structure.

[0051] For example, the electric push rod 16 passes laterally through two edge cross shafts 152 at the same height, for bringing the two edge cross shafts 152 at the same height closer together or further apart.

[0052] Specifically, in this embodiment, the electric push rod 16 is fixedly connected to one of the two edge cross shafts 152 at the same height and is driven to the other, thereby enabling the two edge cross shafts 152 at the same height to approach or move away from each other.

[0053] When two edge intersection axes 152 at the same height approach each other, the scissor lift bracket 15 extends vertically and the lamp 22 descends; when two edge intersection axes 152 at the same height move away from each other, the scissor lift bracket 15 shortens vertically and the lamp 22 rises.

[0054] For example, the hinge shaft 2111 of the hinge 211 and the flip motor shaft 2121 of the flip motor 212 are connected by a gear set 213.

[0055] Specifically, in this embodiment, the gear set 213 includes four gears, wherein the gear at the right end corresponds to the hinge shaft 2111, and the gear at the left end corresponds to the flip motor shaft 2121.

[0056] For example, the number of teeth of the gear corresponding to the hinge shaft 2111 is greater than the number of teeth of the gear corresponding to the flip motor shaft 2121.

[0057] Specifically, in this embodiment, by setting the number of teeth of the gear corresponding to the hinge shaft 2111 to be greater than the number of teeth of the gear corresponding to the flip motor shaft 2121, the hinge shaft 2111 rotates less than one revolution when the flip motor shaft 2121 rotates one revolution. That is, the rotational angular velocity of the hinge shaft 2111 is slower than that of the flip motor shaft 2121, thereby improving the accuracy of the lamp 22 flipping.

[0058] For example, the control unit is also electrically connected to a light intensity sensor.

[0059] Specifically, the light intensity sensor can monitor the light intensity inside the low studio and the light intensity of the lamps 22, thus providing a basis for dimming.

[0060] For example, the flip motor 212 is a self-locking motor.

[0061] Specifically, the use of a self-locking motor allows the lamp 22 to be locked at any angle during the flipping process, thereby improving the stability and fixability of the lamp flipping.

[0062] This embodiment of the application achieves the lifting, flipping, and dimming functions of the lighting fixture by setting up a lifting mechanism, a flipping mechanism 21, and a control unit, which can meet the diverse adjustment needs of low-ceiling studios for embedded lighting fixtures. Specifically, the lifting function is achieved through the upper platform 11, upper mounting bracket 12, lower platform 13, lower mounting bracket 14, scissor-type lifting bracket 15, and electric push rod 16; the flipping function is achieved through the hinge 211 and flipping motor 212; and the dimming function is achieved through the control unit and dimming chip.

[0063] The proposed scissor lift support 15 includes at least two sets in the front-to-back direction, and each set of scissor lift support 15 includes at least one scissor structure in the vertical direction; a central cross axis 151 is provided between the central intersection points of the scissor structures at the same height in the front and back, and an edge cross axis 152 is provided between the edge intersection points, which improves the structural stability and support of the scissor lift support 15.

[0064] The hinge shaft 2111 of the proposed hinge 211 is connected to the flip motor shaft 2121 of the flip motor 212 by a gear set 213; the number of teeth of the gear corresponding to the hinge shaft 2111 is more than the number of teeth of the gear corresponding to the flip motor shaft 2121, which improves the accuracy of the flipping of the lamp 22.

[0065] The proposed control unit is electrically connected to a light intensity sensor, providing a basis for dimming.

[0066] The proposed flip motor 212 adopts a self-locking motor, which improves the stability and fixability of the lamp flipping.
