Description

Technical Field

[0001] This application belongs to the field of lighting equipment technology, and more specifically, relates to a rotatable wall lamp. Background Technology

[0002] In the lighting field, wall lamps, as important products for indoor and outdoor wall decoration and functional lighting, are widely used in homes, hotels, corridors, and other places. They not only provide local lighting but also often beautify the space through their design. However, existing wall lamps generally suffer from inconvenient lamp head adjustment in actual use. Most products use a fixed connection to install the lamp head on the lamp body, making it difficult to flexibly adjust the illumination direction after installation. The only way to indirectly adjust the illumination range is by changing the installation position or angle of the entire wall lamp. This method is not only cumbersome but also highly limited by the installation environment, making it difficult to meet users' personalized needs for illumination direction in different scenarios.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0022] like Figure 1 and Figure 2 As shown, this application provides a rotatable wall lamp, including a lamp holder assembly 1, a rotating shaft assembly 2, and a lamp tube assembly 3.

[0023] The lamp holder assembly 1 includes a housing 11 and electrical components disposed inside the housing 11. The housing 11 is used for fixed installation on external base surfaces such as walls and columns. Its shape is usually adapted to the installation size of conventional wall lamps to provide a stable support base. The electrical components include necessary components such as power modules and control circuits to provide power support and control logic for the overall operation of the wall lamp.

[0024] The rotating shaft assembly 2 includes a shaft 21 and an electrical terminal 22. One end of the shaft 21 is rotatably connected to the housing 11 around a first axis, which is perpendicular to the mounting plane of the housing 11. The other end of the shaft 21 extends along a second axis to form a socket 211. The second axis is set at an angle to the first axis. This angle can be designed as an acute angle, a right angle, or other angles according to actual illumination requirements to expand the adjustment range of the lamp assembly 3. The electrical terminal 22 is fixed to the inner wall or bottom of the socket 211. One end of the terminal is electrically connected to the electrical components inside the housing 11 through a wire or a conductive slip ring, and the other end is exposed inside the socket 211 to make contact with external plug-in components.

[0025] The lamp assembly 3 is rotatably inserted into the socket 211 of the shaft 21 and maintains reliable electrical contact with the electrical terminal 22, so that the lamp assembly 3 can rotate relative to the shaft 21 around the second axis within the socket. At the same time, since the shaft 21 itself can rotate relative to the housing 11 around the first axis, the lamp assembly 3 can ultimately achieve multi-angle illumination direction adjustment through the cooperation of the two rotating joints. When the lamp assembly 3 is powered on, it can emit light, and its illumination direction changes with the rotation of the shaft 21 around the first axis and the rotation of the lamp assembly 3 around the second axis, thereby realizing the adjustment of different lighting areas and meeting the illumination angle requirements in different scenarios.

[0026] In some specific embodiments of this application, there are multiple sockets 211. Each socket 211 is uniformly or non-uniformly arranged on the end face or circumferential sidewall of the shaft 21 away from the housing 11 along the circumferential direction of the first axis. The first axis is the axis on which the shaft 21 rotates around the housing 11. When there are multiple sockets 211, the center line connecting the sockets 211 can form a virtual circumference perpendicular to the first axis. The included angle between adjacent sockets 211 along the circumferential direction can be set according to the actual lighting coverage requirements, such as 30°, 45° or 60°, so as to achieve rapid positioning of the initial orientation of the lamp assembly 3 by selecting sockets 211 at different positions. At this time, the lamp assembly 3 is rotatably inserted into one of the selected sockets 211. Its rotation range around the second axis is still limited by the structure of the socket 211. The circumferential distribution of the sockets 211 along the first axis allows the second axis direction of the lamp assembly 3 to point to different directions after the shaft 21 rotates around the first axis to different angles. Thus, without changing the rotation angle of the shaft 21, the initial illumination direction of the lamp assembly 3 can be adjusted simply by changing the socket 211, further expanding the adjustment dimension of the wall lamp's illumination angle. At the same time, the arrangement of multiple sockets 211 must ensure that the electrical terminals 22 in each socket 211 are electrically connected to the electrical components in the housing 11. This can be achieved by setting conductive lines or conductive ring structures inside the shaft 21, so that the electrical terminals 22 in each socket 211 are connected in parallel or connected to the electrical components through a switching structure, ensuring stable power supply when the lamp assembly 3 is inserted into any socket 211. This circumferential arrangement of multiple sockets 211, by increasing the optional connection position between the lamp tube assembly 3 and the shaft 21, realizes the graded adjustment of the illumination angle. Combined with the continuous rotation of the shaft 21 around the first axis and the rotation of the lamp tube assembly 3 around the second axis, a multi-level linkage angle adjustment mechanism is formed, which improves the adaptability of the wall lamp to different application scenarios.

[0027] like Figure 1 and Figure 2As shown, in some specific embodiments of this application, the shaft 21 includes a first rotating shaft portion 212 and a second rotating shaft portion 213, which are integrally formed or connected by detachable parts. The first rotating shaft portion 212 extends along the first axis direction, and one end of it is rotatably connected to the housing 11 through a bearing, bushing or pivot structure to realize the rotation of the shaft 21 as a whole relative to the housing 11 around the first axis. The other end of the first rotating shaft portion 212 is fixedly connected to one end of the second rotating shaft portion 213 or integrally formed. The second rotating shaft portion 213 extends along the second axis direction, and the second axis is set at an angle with the first axis. The insertion hole 211 is opened at the end of the second rotating shaft portion 213 away from the first rotating shaft portion 212, and its extension direction is consistent with the second axis, for the insertion part of the lamp tube assembly 3 to be inserted.

[0028] A first axial channel is provided inside the first rotating shaft 212 along the first axis, and its diameter is determined according to the internal wiring requirements. A second axial channel is provided inside the second rotating shaft 213 along the second axis. The second axial channel and the first axial channel are connected at the connection of the shaft body 21, forming a continuous channel extending from the housing 11 to the inside of the socket 211. An electrical terminal 22 is installed in the second axial channel. One end of the terminal is electrically connected to the electrical components inside the housing 11 through a wire passing through the first and second axial channels. The other end is fixed to the end port or inner wall of the second axial channel near the socket 211. When the plug part of the lamp tube assembly 3 is inserted into the socket 211, the conductive contact in the plug part can make contact with the exposed part of the electrical terminal 22 to conduct electricity, thereby realizing the current path from the electrical components inside the housing 11 through the wire and the electrical terminal 22 to the lamp tube assembly 3. The split-axis design of the first rotating shaft 212 and the second rotating shaft 213 allows the shaft 21 to deflect the lamp assembly 3 around the first direction by rotating the first rotating shaft 212 and the first axis. At the same time, the rotation of the second rotating shaft 213 and the second axis, in conjunction with the rotation of the lamp assembly 3 itself, allows the lamp assembly 3 to deflect around the second direction. The connection structure between the first axis channel and the second axis channel provides a physical path for the electrical connection between the electrical terminal 22 and the electrical components inside the housing 11, avoiding wire tangling or pulling caused by the rotation of the shaft 21, and ensuring the stability of the electrical connection during rotation.

[0029] like Figure 3As shown in some specific embodiments of this application, the lamp assembly 3 includes a light-emitting tube 31, a connector 32, and a terminal block 33. The light-emitting tube 31 is installed at one end of the connector 32 and is used to emit illumination light; the terminal block 33 is installed at the other end of the connector 32 and has conductive contacts inside for establishing an electrical connection with an external electrical terminal 22. When the lamp assembly 3 is inserted into the socket 211, at least a portion of the length of the connector 32 is inserted into the socket 211, and its outer diameter matches the inner diameter of the socket 211 to ensure the stability of the insertion. Simultaneously, the terminal block 33 is located inside or at the end of the socket 211, corresponding to and conducting with the electrical terminal 22 within the socket 211. Specifically, the terminal block 33 can adopt a DC female connector structure, and the electrical terminal 22 corresponds to a DC male connector structure. The two achieve electrical connection through mating. The mating interface of the DC male and female connectors can be divided into different forms depending on the number of conductive channels. When a three-channel DC male and female connector is used for connection, the three conductive channels correspond to the cold light drive signal, the warm light drive signal, and the common positive power supply signal, respectively. By controlling the driving current of the cold light and the warm light respectively, the ratio of cold light to warm light in the light emitted by the lamp tube 31 can be adjusted, thereby realizing the output of different color temperature light, cold light, warm light, and the mixture of the two. When a four-channel DC male and female connector is used for connection, the four conductive channels correspond to the positive power supply signal, single-port communication RGB, warm light, and ground drive signal, respectively. By controlling the current intensity of each channel, the lamp tube 31 can emit different proportions of red, green, blue, and self-mixed light, thereby realizing the display effect of multiple optical modes such as RGBW.

[0030] The connector 32 is designed to fit the shape and insertion direction of the socket 211. It is typically made of insulating plastic and can house internal wires for connecting to the lamp tube 31 and terminal block 33 to conduct current and transmit control signals, ensuring that the lamp tube 31's operating state is controlled by the external drive circuit. This multi-channel connection via DC male and female connectors not only enables a detachable electrical connection between the lamp tube assembly 3 and the rotating shaft assembly 2, facilitating the replacement or maintenance of the lamp tube assembly 3, but also allows for the expansion of optical modes within the same wall lamp structure based on varying channel numbers. A three-channel interface provides color temperature adjustment, while a four-channel interface further enables colored light output, enhancing the wall lamp's functional versatility and application flexibility.

[0031] like Figure 3As shown in some specific embodiments of this application, the light-emitting tube 31 includes a tube body 311, a lamp plate 312, and a lamp cover 313. The tube body 311 is installed at one end of the connector 32. Its shape is usually elongated or cylindrical, and its material can be metal or engineering plastic. It is used to provide support and protection for internal components. The side wall of the tube body 311 has a radially open opening. The length direction of the opening is generally consistent with the extension direction of the tube body 311, and the width is determined according to the size of the lamp plate 312 so that the lamp plate 312 can be inserted into or removed from the tube body 311 through the opening. The lamp plate 312 is installed inside the tube body 311. Its shape is adapted to the inner cavity cross section of the tube body 311. It is usually a strip or plate structure, and its surface is covered with light-emitting elements such as LED chips. The lamp plate 312 is fixed to the inner wall of the tube body 311 by means of clips, screws, or adhesives. Its light-emitting surface faces the opening direction of the tube body 311 so that light can be emitted through the opening. The lampshade 313 covers the opening of the tube body 311, and its edge is fixed to the outer wall of the tube body 311 or the edge of the opening by means of snap-fit, threaded connection or adhesive. The material can be transparent or translucent PC, PMMA or other materials. It is used to diffuse, homogenize or distribute the light emitted by the lamp panel 312, to avoid glare caused by direct light emission, and to protect the lamp panel 312 from dust or external damage. The connection between the connector 32 and the tube body 311 is usually provided with a sealing structure to prevent dust or moisture from entering the tube body 311 and affecting the operation of the lamp panel 312. In this structure, the tube body 311 serves as a carrier for accommodating the lamp panel 312. The lamp panel 312 is easily installed and replaced through a radial opening. The lampshade 313 controls the light and protects the internal components by covering the opening. The three work together to form a complete light-emitting tube 31. When the lamp tube assembly 3 is inserted into the socket 211, the extension direction of the tube body 311 is consistent with the overall orientation of the lamp tube assembly 3. The light-emitting surface of the lampshade 313 is the illumination surface of the wall lamp, and its illumination angle changes with the rotation of the lamp tube assembly 3 around the second axis and the rotation of the shaft 21 around the first axis.

[0032] In some specific embodiments of this application, the connector 32 is integrally formed using a die-casting process. Its material is typically a suitable die-casting metal such as aluminum alloy or zinc alloy. During the die-casting process, structural features such as the mounting position for connection to the tube body 311, the receiving groove for embedding the terminal block 33, and the insertion section for mating with the socket 211 can be directly formed using a mold. This eliminates the need for multiple machining processes such as turning and milling to form the main structure, reducing machining steps and tool wear, which helps to lower the production cost of the connector 32 and improve production efficiency. The terminal block 33 is a rubber-coated DC female connector with an internal socket structure that matches the electrical terminal 22. The terminal block 33 is embedded in the end of the connector 32 away from the tube body 311 by interference fit, snap-fit, or bonding. The embedding position corresponds to the insertion direction of the connector 32, ensuring that when the lamp assembly 3 is inserted into the socket 211, the terminal block 33 can accurately connect and conduct with the electrical terminal 22 inside the socket 211. The die-cast structure of connector 32 ensures its mechanical strength while meeting the fitting requirements of tube body 311 and terminal block 33 through mold forming precision. The design of terminal block 33 being embedded in connector 32 integrates the electrical connection structure into connector 32, avoiding positional deviations that may occur if terminal block 33 is installed separately, and ensuring the reliability of the electrical connection when lamp tube assembly 3 and shaft assembly 2 are plugged in. This structural design simplifies the processing of connector 32 through die casting and optimizes the installation stability of terminal block 33 through embedding, which helps to improve the overall assembly efficiency and structural consistency of lamp tube assembly 3.

[0033] like Figure 1 and Figure 2As shown in some specific embodiments of this application, the lamp holder assembly 1 further includes a mounting base plate 12. The shape and size of the mounting base plate 12 are adapted to the mounting foundation of a conventional wall lamp, such as a rectangular, circular, or square flat plate structure. It is provided with mounting holes or a snap-fit ​​structure for fixing the lamp holder assembly 1 to the external foundation surface such as a wall or column. The fixing method can be achieved by expansion bolts, self-tapping screws, or adhesive to provide a stable support foundation. The housing 11 is mounted on the mounting base plate 12, and the two are connected by a detachable connection method, such as snap-fit, threaded connection, or magnetic structure. The snap-fit ​​can be locked by the interlocking of the latch at the bottom of the housing 11 and the slot on the mounting base plate 12. It can be separated by pressing the unlock button. The threaded connection is achieved by providing interlocking screw holes and screws on the housing 11 and the mounting base plate 12. The magnetic structure can embed a magnet in the mounting base plate 12 and provide ferromagnetic material or another magnet at the corresponding position of the housing 11 to fix it by magnetic attraction. This detachable connection method allows the housing 11 to be completely removed from the mounting base 12. When the wall lamp is powered by a built-in battery or has a charging function, removing the housing 11 allows for direct charging of the battery without disassembling the entire wall lamp or damaging the installation structure, simplifying the charging process. The detachable design of the mounting base 12 and housing 11 ensures convenient charging while maintaining a fixed connection between the lamp holder assembly 1 and the external foundation. This ensures the wall lamp can remain stably installed in its position via the mounting base 12 even when not charging, preventing instability caused by frequent removal of the entire wall lamp. The connection structure between the housing 11 and the mounting base 12 must ensure it will not accidentally loosen during normal use and can be easily separated when charging is required. For example, the snap-fit ​​structure can be equipped with an anti-accidental unlocking mechanism, and the threaded connection can use easy-to-tighten hand screws to meet the operational needs of different usage scenarios.

[0034] like Figure 1 and Figure 2As shown, in some specific embodiments of this application, the lamp holder assembly 1 further includes a magnetic chuck 13. The housing 11 includes an upper cover 111 and a lower cover 112. The magnetic chuck 13 is installed on the lower cover 112. Its material is usually a permanent magnet or a magnetizable metal material, such as a neodymium iron boron magnet, a ferrite magnet, or a stainless steel sheet. The specific installation position is determined according to the mating structure between the housing 11 and the mounting base plate 12. It can be embedded in the groove on the side of the housing 11 facing the mounting base plate 12, pasted to the bottom surface of the housing 11, or embedded in the injection molding structure of the housing 11. The installation methods include gluing, snap-fitting, or in-mold embedding, to ensure that the magnetic chuck 13 is firmly attached to the housing 11 and the position is accurate. The mounting base 12 has a material layer or additional magnetic component, such as a ferromagnetic metal plate, another magnet, or a magnetic sheet, at the position corresponding to the magnetic component 13. When the housing 11 is close to the mounting base 12, the corresponding part of the magnetic component 13 and the mounting base 12 attract each other magnetically, allowing the housing 11 to be stably magnetically connected to the mounting base 12 without the need for additional clips or screws. This magnetic connection method uses magnetic force to achieve quick assembly and disassembly of the housing 11 and the mounting base 12. During operation, only a certain external force needs to be applied to overcome the magnetic force to separate the housing 11, facilitating the charging or replacement of the battery inside the housing 11, or quickly removing the housing 11 when the position of the wall lamp needs to be adjusted, improving the convenience of use. The magnetic force of the magnetic component 13 needs to be determined according to the weight of the wall lamp and the usage environment, ensuring that the housing 11 will not detach from the mounting base 12 due to gravity or slight vibration during normal use, while also ensuring that the external force required for disassembly is within an ergonomically acceptable range. The connection between the housing 11 and the mounting base plate 12 via the magnetic connector 13, in conjunction with the aforementioned detachable connection design, further enhances the ease of assembly and disassembly. This is especially suitable for application scenarios where the housing 11 needs to be frequently removed for charging. At the same time, the hidden or recessed installation method of the magnetic connector does not affect the overall appearance of the wall lamp, maintaining its aesthetics and compact structure.

[0035] like Figure 1 and Figure 2As shown in some specific embodiments of this application, the electrical components include a control board 14 and a battery 15, both of which are housed inside the housing 11 and electrically connected to the control board 14 via wires or circuit board traces. The control board 14 is a printed circuit board structure, integrating electronic components such as a power management module, signal processing circuit, and drive control unit. It is used to control the overall working state of the wall lamp, including receiving external control signals, adjusting the brightness, color temperature, or color mode of the light-emitting tube 31, and managing the charging and discharging of the battery 15. The battery 15 is installed inside the housing 11 adjacent to the control board 14. Its type can be selected according to the power requirements of the wall lamp, such as a lithium-ion battery, nickel-metal hydride battery, or lithium iron phosphate battery. It is used to store electrical energy and power the wall lamp. When the wall lamp is connected to an external power source, the control board 14 converts the external electrical energy into a suitable voltage and current through the power management module to charge the battery 15. When the wall lamp is in an off-grid state, the battery 15 supplies power to the light-emitting tube 31 and the control board 14 itself through the control board 14. Electrical terminal 22 is electrically connected to control board 14. The connection path can be achieved through wires passing through the first and second axial channels, allowing electrical terminal 22 to transmit the drive signal output from control board 14 to terminal block 33 of lamp assembly 3 when lamp tube assembly 3 is plugged into socket 211, thereby controlling the working state of lamp tube 31. The electrical connection between control board 14 and battery 15 forms an independent power supply circuit for the wall lamp, enabling it to operate normally without an external power source. Simultaneously, the charge / discharge management function of control board 14 prevents overcharging and over-discharging of battery 15, extending its lifespan. This configuration of electrical components, through control board 14, achieves centralized control of battery 15 charging / discharging and lamp tube assembly 3 illumination. Electrical terminal 22, as the signal transmission interface between control board 14 and lamp tube assembly 3, ensures stable transmission of control signals and electrical energy during rotational connection, meeting the electrical control requirements of the rotatable wall lamp for mobile use, angle adjustment, and multi-functional lighting.

[0036] In some specific embodiments of this application, the rotating shaft assembly 2 can rotate around the first axis in an angle range of 0° to 350°. This angle range is achieved by a rotation limiting structure provided between the first rotating shaft part 212 and the housing 11. For example, a protrusion and a limiting groove are provided on the housing 11 or the first rotating shaft part 212. When the first rotating shaft part 212 rotates around the first axis to abut against the limiting structure, the maximum rotation angle is reached. The rotation range of 0° to 350° not only avoids the cable entanglement problem caused by the complete circumferential rotation of the shaft 21 and the first rotating shaft part 212, but also covers the adjustment needs of the horizontal or tilted illumination angle of the wall lamp in most practical use scenarios, so that the overall orientation of the lamp tube assembly 3 can be adjusted within a range close to the full circumference. Alternatively, the lamp assembly 3 can rotate within an angle range of 0° to 360° around the second axis. This angle range is achieved by setting an annular rotational fit structure between the inner wall of the insertion hole 211 of the second rotating shaft 213 and the terminal block 33 of the lamp assembly 3. For example, the outer periphery of the terminal block 33 and the inner hole of the second rotating shaft 213 are fitted with a clearance fit, allowing the terminal block 33 to drive the light-emitting lamp 31 to rotate a full circle around the second axis. The rotation range of 0° to 360° allows the light-emitting lamp 31 to achieve pitch or deflection adjustment at any angle in a plane perpendicular to the first axis. Combined with the rotation of the rotating shaft assembly 2 around the first axis, the illumination coverage of the wall lamp can be further expanded to meet different needs such as precise focused lighting or wide-angle lighting for specific areas. The two angle ranges can be selected according to the specific application of the wall lamp. When the focus is on avoiding cable tangling, the rotation range of the pivot assembly 2 from 0° to 350° can be used. When the focus is on the full-range pitch adjustment of the lamp tube assembly 3, the rotation range of the lamp tube assembly 3 from 0° to 360° can be selected. Both can achieve angle limit through the structural design that cooperates with their respective rotation axes, ensuring that the rotation process is smooth and there is no structural interference.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
