[0027] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0028] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0029] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0030] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] like Figure 1 and Figure 2 As shown, a lighting fixture of an embodiment includes a liftable stand 10, the liftable stand 10 includes a controller, a power unit 11, a fixed frame 12 and a movable frame 13, the controller and the power unit 11 are respectively installed in the fixed frame 12, and the controller is electrically connected to the power unit 11, the movable frame 13 is installed on the fixed frame 12 so as to be liftable and movable and is connected to the power unit 11 by driving; a remote controller, the remote controller is connected to the signal receiving module of the controller by wireless communication; a lighting module 20, the lighting module 20 includes a lighting lamp 21, a cantilever frame 22 and a distance detection component 23, the cantilever frame 22 is arranged at the upper end of the movable frame 13, The lighting lamp 21 can be horizontally rotatably installed on the cantilever frame 22, and the lighting lamp 21 at least includes a first side surface 211 and a second side surface 212. The distance detection component 23 is arranged at one end of the cantilever frame 22 close to the movable frame 13. When the first side surface 211 faces the distance detection component 23, the distance between the first side surface 211 and the distance detection component 23 is set to a first distance. When the second side surface 212 faces the distance detection component 23, the distance between the first side surface 211 and the distance detection component 23 is set to a second distance, and the second distance is not equal to the first distance. The distance detection component 23 is electrically connected to the controller, and the distance detection component 23 is also used to detect the distance between the lighting lamp 21 and the bearing surface.

[0032] In addition, the lighting fixture also includes a base, and the lower end of the fixing frame 12 is mounted on the base. The base can be placed on the bearing surface to achieve the installation and fixation of the entire lighting fixture.

[0033] For example, in this embodiment, the base is a U-shaped plate, so that there is a larger support area between the base and the bearing surface, which can ensure that the lighting fixture is installed more stably. In addition, when the lighting fixture is a floor lamp, the U-shaped groove of the U-shaped plate can be connected with the seat legs, cabinet legs, table corners, etc. to achieve the clamping and positioning of the floor lamp, improve the stability of the installation of the floor lamp, and prevent it from tipping over when accidentally affected by external forces.

[0034] The implementation of the embodiment of the utility model will have the following beneficial effects: when the user uses the lighting fixture of the present solution, the handheld remote control sends a lifting signal to the signal receiving module of the controller, and the power unit 11 will drive the movable frame 13 to rise or fall accordingly. At this time, the distance detection component 23 detects the change in the distance between the lighting lamp 21 and the bearing surface in real time, that is, when the movable frame 13 rises, the distance between the lighting lamp 21 and the bearing surface increases, and the distance detection component 23 feeds back a signal to the controller, and the controller increases the output current to the lighting lamp 21 to increase the brightness of the lighting lamp 21. On the contrary, when the movable frame 13 drives the lighting lamp 21 to descend, it will The brightness of the lighting lamp 21 is lowered accordingly; in addition, the user can also manually rotate the lighting lamp 21. Since the first side 211 and the second side 212 of the lighting lamp 21 are at different distances from the distance detection component 23, when the lighting lamp 21 is rotated so that the first side 211 or the second side 212 is directly opposite to the distance detection component 23, the distance detection component 23 detects that the distance between it and the lighting lamp 21 is different, so that when the distance between the distance detection component 23 and the lighting lamp 21 becomes smaller, the controller controls the current input to the lighting lamp 21 to decrease, and the brightness of the lighting light of the lighting lamp 21 is reduced. Otherwise, the brightness of the lighting light of the lighting lamp 21 is increased.

[0035] This solution can achieve multi-level stepless adjustment of the brightness of the lighting light by detecting the distance to control the brightness of the lighting lamp 21. It can obtain lighting lights of various brightnesses within a large adjustment range, thereby meeting the different lighting needs of different users. The adjustment method can be remote control by a remote control or manual rotation of the lighting lamp 21. It has various usage methods, is convenient and labor-saving to operate, and helps to improve the user experience.

[0036] It is easy to understand that the controller is provided with a current regulating circuit, which can control the magnitude of the current input into the lighting lamp 21. The current regulating circuit can adopt a mature current control circuit in the prior art, so it will not be described in detail here.

[0037] In one embodiment, the distance detection component 23 includes a first distance sensor 231, and the first distance sensor 231 is arranged at an angle with the lifting direction of the movable frame 13, so that the detection head of the first distance sensor 231 is tilted and arranged toward the illuminating lamp 21. The first distance sensor 231 is arranged separately for detecting the distance between the illuminating lamp 21, which can avoid interference that may be caused by other detection data, and is conducive to improving the accuracy of the detection result; in addition, the first distance sensor 231 is arranged in an inclined posture, so that the detection head of the first distance sensor 231 can be arranged in front of the illuminating lamp 21, shortening the round trip of the detection light emitted by the first distance sensor 231, thereby improving the detection efficiency.

[0038] Optionally, the first distance sensor 231 may be, but is not limited to, an infrared sensor, a laser sensor, or the like.

[0039] It should be noted that the illuminating lamp 21 is rectangular, and the first side surface 211 and the second side surface 212 respectively refer to a long side and a short side adjacent to the illuminating lamp 21. Obviously, when the short side faces the first distance sensor 231, the long side can extend the short side toward the first distance sensor 231, so that the distance between the first distance sensor 231 and the short side is small; when the long side faces the first distance sensor 231, the length of the short side is small, resulting in the long side being further away from the first distance sensor 231, so that the distance between the first distance sensor 231 and the long side is large.

[0040] In addition, in one embodiment, the distance detection assembly 23 further includes a second distance sensor 232, which is arranged parallel to the lifting direction of the movable frame 13, so that the detection head of the second distance sensor 232 is arranged toward the bearing surface. The second distance sensor 232 is dedicated to detecting the vertical distance between the lighting lamp 21 and the bearing surface, and is not subject to detection interference from the first distance sensor 231, which is conducive to ensuring the accuracy of the detection result.

[0041] Optionally, the second distance sensor 232 may be, but is not limited to, an infrared sensor, a laser sensor, or the like.

[0042] like Figure 3 As shown, in one embodiment, the power unit 11 includes a motor 111, a transmission screw 112 and a transmission nut 113. The motor 111 is arranged at the bottom of the fixed frame 12 and connected to one end of the transmission screw 112. The transmission nut 113 is screwed to the outside of the transmission screw 112, and the transmission nut 113 is connected to the lower end of the movable frame 13 extending into the fixed frame 12. During operation, the motor 111 rotates forward, driving the transmission screw 112 to rotate forward, and the transmission nut 113 can move upward along the axial direction of the transmission screw 112, and the movable frame 13 can move upward under the push of the transmission nut 113; on the contrary, the motor 111 rotates reversely, which can drive the transmission screw 112 to rotate reversely, and the transmission nut 113 can move downward along the axial direction of the transmission screw 112, and the movable frame 13 can move downward under the pull of the transmission nut 113. The power unit 11 has a simple structure and working principle. The transmission force of the transmission screw 112 and the transmission nut 113 is stable and has a strong load capacity. The lighting lamp 21 can be smoothly raised and lowered and stopped at any height position so that the lighting lamp 21 can emit lighting light of various intensities to meet the needs of different users.

[0043] Furthermore, the power unit 11 further includes a first guide rail and a second guide rail, which are arranged in the fixed frame 12 at intervals, and the first and second slide grooves are respectively provided on the opposite side walls of the movable frame 13, and the first guide rail is installed in the corresponding first slide groove and can slide along the first slide groove, and the second guide rail is installed in the corresponding second slide groove and can slide along the second slide groove. Firstly, by sliding the first guide rail in the first slide groove and the second guide rail in the second slide groove, a guiding effect can be formed for the lifting and lowering movement of the movable frame 13; secondly, the two sets of slide groove guide rail structures respectively limit the lateral freedom of movement of the movable frame 13 from the opposite sides, which can prevent the movable frame 13 from swinging and affecting the smoothness of the lifting and lowering operation of the movable frame 13.

[0044] In one embodiment, the lighting fixture further includes a display screen 30. The movable frame 13 is provided with an installation window 131. The display screen 30 is disposed in the movable frame 13 and assembled with the installation window 131. The display screen 30 can display information such as time, battery life, ambient temperature, and light intensity, thereby enriching the functions of the lighting fixture and enhancing the usability of the lighting fixture.

[0045] In addition, in one embodiment, the lighting module 20 includes a rotating shaft 40, and the lighting lamp 21 is rotatably connected to the cantilever frame 22 via the rotating shaft 40. Therefore, the rotating shaft 40 provides the lighting lamp 21 with a horizontal rotational degree of freedom, so that the lighting lamp 21 can rotate at any angle of 360° clockwise or counterclockwise relative to the cantilever frame 22.

[0046] like Figure 4 As shown, in the above embodiment, the lighting lamp 21 includes a lamp housing 213, a lamp cover 214, a connecting frame 215 and a light bar 216. The lamp housing 213 and the lamp cover 214 are detachably connected, the connecting frame 215 is connected to the rotating shaft 40, and the light bar 216 is arranged on the connecting frame 215. The side of the lamp housing 213 away from the lamp cover 214 is set as the light-emitting surface, and the light bar 216 is arranged facing the light-emitting surface. The lamp housing 213 and the lamp cover 214 are designed to be detachable, which is convenient for assembling the connecting frame 215, the light bar 216, etc. during production and replacing damaged parts during maintenance. When the lamp housing 213 is rotated, the lamp housing 213 can synchronously drive the rotating shaft 40, the light bar 216 and the top cover to rotate relative to the cantilever frame 22 through the connecting frame 215 to adjust the lighting intensity.

[0047] For example, the connecting frame 215 is a frame structure formed by welding a plurality of horizontal bars and vertical bars, which has a simple structure and high strength, and can effectively support the lamp housing 213 from the inside to prevent the lamp housing 213 from deforming when being squeezed and impacted by external forces. According to actual needs, the connection method of the above components can be any one of screw connection, clamp connection, bonding, etc., or a combination of at least two or more.

[0048] For example, the light bar 216 is specifically an LED light bar 216, which is specifically composed of a PCB board and LED lamp beads welded on the PCB board. The LED lamp beads can be one, or two or more.

[0049] To further improve the stability of the installation of the light bar 216, in one embodiment, a positioning protrusion 50 is provided on the side of the light emitting surface facing the light bar 216, and a positioning hole is provided in the light bar 216, and the positioning protrusion 50 is inserted into the positioning hole. Specifically, the positioning hole is provided on the PCB board.

[0050] In order to timely and effectively remove the heat generated by the light bar 216 during operation and prevent the high temperature environment from affecting the service life of the electrical components, in one embodiment, the side wall of the lamp housing 213 is provided with heat dissipation ventilation holes.

[0051] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
