Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lamps, in particular to a lamp panel structure and a lamp. BACKGROUND

[0002] Wall lamps are commonly used as auxiliary lighting devices in indoor environments, usually designed with low-power light sources to provide lighting for small local areas.

[0003] In practical applications, conventional wall lamps generally have a fixed downward illumination structure. For example, a wall lamp installed at the head of a bed can only cover a limited area directly below, resulting in a significant bright-dark boundary between the illuminated area and the surrounding environment. This uneven light distribution pattern can easily cause visual discomfort for users during daily use. Prolonged exposure to such lighting environments can cause eye strain, dryness, and even headaches, and can also interfere with the body's natural circadian rhythm, affecting mental state and sleep quality. On the other hand, if a full environmental lighting solution is used to alleviate the problem of excessive brightness in a local area, it is often difficult to control the lighting range due to the high overall light intensity. In particular, in a nighttime rest scenario, strong light can directly interfere with the sleep of others in the same room, causing unnecessary disturbance. The existing wall lamp technology has obvious limitations in terms of lighting direction adjustment and light environment adaptability, and cannot balance the needs of local lighting and overall environmental compatibility, resulting in poor user experience.

[0023] As Figures 1-5As shown, the embodiment of the present application proposes a wall lamp, which comprises a lamp holder 1 and a light-emitting module 2. The light-emitting module 2 comprises a module support 21, a light-emitting unit 22, a first light guide column 23, and a second light guide column 24. The module support 21 is a ring-shaped hollow structure. The light-emitting unit 22 comprises at least a first light-emitting unit 221 and a second light-emitting unit 222. The light-emitting surfaces of the first light-emitting unit 221 and the second light-emitting unit 222 are arranged oppositely. The first light-emitting unit 221 and the second light-emitting unit 222 are arranged in the module support 21. The light entrance surface of the first light guide column 23 corresponds to the light exit surface of the first light-emitting unit 221. The light entrance surface of the second light guide column 24 corresponds to the light exit surface of the second light-emitting unit 222. The light-emitting module 2 is rotatably connected to the lamp holder 1 through the module support 21. The ring-shaped hollow structure of the module support 21 can be understood as a frame structure with a central through hole. Its main function is to provide installation space for the light-emitting unit 22 and the light guide column, and to ensure that the light can propagate along the predetermined path. In practical applications, the ring-shaped hollow structure can be manufactured by injection molding process. The material can be selected from plastics with high temperature resistance and good mechanical strength, such as polycarbonate or ABS resin. The light-emitting surfaces of the first light-emitting unit 221 and the second light-emitting unit 222 are arranged oppositely. This arrangement is designed to achieve the function of bidirectional lighting. In practical applications, the first light-emitting unit 221 and the second light-emitting unit 222 can use LED light sources. They can be connected to the driving circuit in series or parallel to achieve independent control or synchronous lighting. Further, the first light-emitting unit 221 and the second light-emitting unit 222 can share one circuit board or have one circuit board respectively. The first light guide column 23 and the second light guide column 24 are mainly used to guide the light emitted by the light-emitting unit to the target area. In practical applications, the first light guide column 23 and the second light guide column 24 can be made of transparent or translucent optical materials, such as PMMA or PC. The surface can be treated by sanding or engraved with microstructure to achieve uniform distribution of light. Further, the shape of the first light guide column 23 and the second light guide column 24 can be designed as cylindrical, prismatic or other special-shaped structures to meet different light propagation and appearance design requirements. The light-emitting module 2 is rotatably connected to the lamp holder 1 through the module support 21. This design allows users to dynamically adjust the lighting direction according to actual needs. In practical applications, rotatable connection can be achieved in various ways, such as setting a bearing structure between the module support 21 and the lamp holder 1, or achieving angle fixation through a friction hinge. Further, the range of rotation angle can be constrained by limiting structure, such as setting a protrusion on the module support 21 and a corresponding groove on the lamp holder 1 to limit the maximum rotation angle. The innovation of the present application is to solve the problem of single illumination range of traditional wall lamp by bidirectional illumination and adjustable direction design. Specifically, the opposite arrangement of the first light emitting unit 221 and the second light emitting unit 222 realizes the propagation of light in opposite directions, thereby expanding the three-dimensional space range of the illumination area and reducing the light difference between the local strong light and the surrounding environment. At the same time, the light emitting module 2 is rotatably connected to the lamp holder 1 through the module support 21, so that the user can flexibly adjust the illumination direction, which not only meets the local illumination demand, but also avoids disturbing others. These designs work together to effectively improve the flexibility of the wall lamp and the uniformity of the light. The working principle of the embodiment of the present application is as follows: the lamp holder 1 is fixedly installed on the wall surface as a basic support structure, providing a stable platform for the whole device. The module support 21 adopts a ring-shaped hollow structure design, which is convenient for the ring-shaped integrated arrangement of the light emitting unit, and the hollow design is beneficial to the bidirectional propagation of light. The light emitting unit 22 includes the first light emitting unit 221 and the second light emitting unit 222, and the light emitting surfaces of the two are arranged opposite to each other, so that the light is emitted in opposite directions, directly expanding the illumination coverage range and reducing the light difference between the local strong light and the surrounding environment caused by single direction illumination. The first light emitting unit 221 and the second light emitting unit 222 are arranged in the module support 21, realizing compact integration, protecting the light source and ensuring the structural stability. The light entrance surface of the first light guide column 23 corresponds to the light exit surface of the first light emitting unit 221, effectively guiding the directional output of the light of the first light emitting unit 221, realizing one-way illumination control; the light entrance surface of the second light guide column 24 corresponds to the light exit surface of the second light emitting unit 222, effectively guiding the directional output of the light of the second light emitting unit 222 in the opposite direction, cooperating with the first light guide column 23 to form a bidirectional illumination capability. Further, the light emitting module 2 is rotatably connected to the lamp holder 1 through the module support 21, allowing the user to dynamically adjust the illumination direction according to the actual demand, avoiding the problem of local strong light caused by fixed downward illumination. Thus, the light emitting units with opposite light emitting surfaces and the corresponding light guide columns jointly realize bidirectional illumination, eliminating the difference in single direction illumination; the rotatable connection mechanism enables the user to flexibly switch the illumination direction, which not only meets the local illumination demand and avoids eye fatigue, but also adjusts the non-interference direction to reduce the impact on others, thereby comprehensively solving the problem of limited illumination range.

[0024] The present application further provides that the inner wall of the module support 21 is provided with a radially extending light emitting unit support 211, the first light emitting unit 221 and the second light emitting unit 222 are arranged on the light emitting unit support 211 in a stacked manner, the light emitting unit support 211 is provided with a plurality of light transmission holes 2110 corresponding to the light exit surface of the second light emitting unit 222, the first light guide column 23 is arranged on one side of the light emitting unit support 211 corresponding to the light exit surface of the first light emitting unit 221, and the second light guide column 24 is arranged on the other side of the light emitting unit support 211 corresponding to the light exit surface of the second light emitting unit 222.

[0025] Specifically, the light-emitting unit bracket 211 refers to a support structure extending from the inner wall of the module bracket 21 towards the center, designed to provide a stable mounting platform for the first light-emitting unit 221 and the second light-emitting unit 222. The light-transmitting hole 2110 is a through-hole structure specifically configured according to the specific position and direction of the light-emitting surface of the second light-emitting unit 222, aiming to allow light to pass through the bracket without obstruction. Through the refined design of the light-emitting unit bracket 211, the installation structure of the light-emitting unit 22 is simplified, while effectively solving the problem of obstructed light transmission from the internal light source in bidirectional lighting. The radially extending light-emitting unit bracket 211 on the inner wall of the module bracket 21 provides a stable radial support platform, enabling the first light-emitting unit 221 and the second light-emitting unit 222 to be precisely installed in a stacked manner. This arrangement not only saves space but also ensures that the two units are closely adjacent, avoiding light scattering caused by installation gaps. The light-transmitting hole 2110 directly addresses the inward-facing characteristic of the second light-emitting unit 222, allowing light to pass through the bracket without obstruction and preventing light from being blocked by the material of the module bracket 21.

[0026] This application further proposes that the radially extending end of the light-emitting unit bracket 211 is provided with a convex edge 2119 extending axially at both ends, a first buckle 2111 is provided on one side of the convex edge 2119, and a second buckle 2112 is provided on the other side; the first light guide post 23 is a hollow columnar structure, and the module bracket 21 also includes a first limiting member 25, the first limiting member 25 is provided with a first latch 251, the first limiting member 25 is connected from the inside of the first light guide post 23 to the first buckle 2111 on the light-emitting unit bracket 211 through the first latch 251; the second light guide post 24 is a hollow columnar structure, and the module bracket 21 also includes a second limiting member 26, the second limiting member 26 is provided with a second latch 261, the second limiting member 26 is connected from the inside of the second light guide post 24 to the second buckle 2112 on the light-emitting unit bracket 211 through the second latch 261.

[0027] Specifically, the protruding edge 2119 refers to a structure with axial extension characteristics formed at the radially extending end of the light-emitting unit bracket 211, which aims to provide an additional mounting surface to enhance structural stability. The first latch 2111 and the second latch 2112 can be understood as elastic fastening structures provided on the protruding edge 2119, designed to form a locking connection with the first limiting member 25 and the second limiting member 26. The first limiting member 25 and the second limiting member 26 are positioning devices for fixing the first light guide post 23 and the second light guide post 24, and also limit the position of the light-emitting unit 22.

[0028] like Figures 4-8As shown, this application further proposes that the wall thickness of the first light guide post 23 is less than the extension length of the light-emitting unit bracket 211. The first limiting member 25 includes a first inner ring structure 253 and a first outer ring structure 255 sleeved and connected to the outside of the first inner ring structure 253. The diameter of the first inner ring structure 253 corresponds to the inner diameter of the annular structure formed by the extension end of the light-emitting unit bracket 211. A first latch 251 is formed on the outer wall of the first inner ring structure 253. The outer wall diameter of the first outer ring structure 255 corresponds to the inner wall diameter of the first light guide post 23 so that the first limiting member 25 passes through the outer wall of the first outer ring structure 255 to the inner wall of the first light guide post 23. The wall is used for limiting; the wall thickness of the second light guide post 24 is less than the extension length of the light-emitting unit bracket 211. The second limiting member 26 includes a second inner ring structure 263 and a second outer ring structure 265 sleeved and connected to the second inner ring structure 263. The diameter of the second inner ring structure 263 corresponds to the inner diameter of the annular structure formed by the extension end of the light-emitting unit bracket 211. The second bayonet 261 is formed on the outer wall of the second inner ring structure 263. The outer wall diameter of the second outer ring structure 265 corresponds to the inner wall diameter of the second light guide post 24 so that the second limiting member 26 limits the inner wall of the second light guide post 24 through the outer wall of the second outer ring structure 265.

[0029] In detail, the design of the first inner ring structure 253 and the second inner ring structure 263 ensures that their diameters closely match the inner diameter of the annular structure at the extended end of the light-emitting unit bracket 211. This matching relationship effectively prevents the limiting component from shifting in the radial direction. Simultaneously, the matching relationship between the outer wall diameters of the first outer ring structure 255 and the second outer ring structure 265 and the inner wall diameter of the light guide post allows the outer ring structure to apply uniform radial pressure to the inner wall of the light guide post, thereby preventing the light guide post from loosening during rotation or vibration. Furthermore, since the first light guide post 23 and the second light guide post 24 correspond to the first light-emitting unit 221 and the second light-emitting unit 222 respectively, this symmetrical design ensures the stability of both sides of the light-emitting module, avoiding uneven lighting caused by loosening on one side. Based on the above structural design, not only is the installation process simplified, but the precise dimensional matching also achieves reliable limiting of the light guide post, significantly improving the structural integrity and lighting quality of the wall lamp during long-term use.

[0030] This application further proposes that the outer walls of the first outer ring structure 255 and the second outer ring structure 265 are respectively provided with a plurality of first protrusions 257 and second protrusions 267, and the first protrusions 257 and the second protrusions 267 form an interference fit with the inner walls of the first light guide post 23 and the second light guide post 24, respectively.

[0031] Specifically, the first protrusion 257 refers to a localized raised structure formed on the outer wall surface of the outer ring structure 255. The second protrusion 267 has a similar definition, and its purpose is to enhance the reliability of the connection by providing continuous radial pressure through an interference fit in a localized area. This design utilizes the elastic deformation characteristics of the material, improving the fixing effect while ensuring assembly feasibility.

[0032] This application further proposes that the first limiting member 25 and the second limiting member 26 are respectively provided with a first radial limiting protrusion 254 and a second radial limiting protrusion 264 that extend radially to axially limit the first light-emitting unit 221 and the second light-emitting unit 222.

[0033] Specifically, the first radial limiting protrusion 254 refers to a structure extending radially outward from the first limiting member 25. It can be formed by integral molding or post-processing, and its purpose is to achieve axial limiting by abutting against the end face of the first light-emitting unit 221. The second radial limiting protrusion 264 refers to a structure extending radially outward from the second limiting member 26. It can also be formed by integral molding or post-processing, and its purpose is to provide axial constraint on the second light-emitting unit 222 to prevent displacement. In fact, the second radial limiting protrusion 264 does not act on the second light-emitting unit 222. Since the second limiting member 26 and the first limiting member 25 are the same structure, the second limiting member 26 will be generated when the same set of molds is used. That is to say, the second limiting member 26 can be used interchangeably with the first limiting member 25.

[0034] like Figure 4 , Figures 9-10 As shown, this application further proposes that the outer wall of the module bracket 21 is provided with a rotating shaft 219 extending toward the lamp holder 1. The lamp holder 1 includes a housing 10 and a shaft end limiting member 11. The housing 10 is provided with a shaft hole 101. The rotating shaft 219 extends through the shaft hole 101 into the housing 10. The shaft end limiting member 11 is connected to the end of the rotating shaft 219 in the housing 10 and forms an axial limit.

[0035] Specifically, the rotating shaft 219 is a key component extending outward from the module bracket 21 and forming a rotatable connection with the lamp holder 1, aiming to provide stable rotational support. The housing 10, as the main structural part of the lamp holder 1, provides the necessary operating environment for the introduction and positioning of the rotating shaft 219 within its internal space. The shaft hole 101 refers to the through-hole structure on the housing 10 used to guide the rotating shaft 219 through. The shaft end limiting member 11 is a component installed inside the housing 10 and engaging with the end of the rotating shaft 219. It can be axially fixed through screw connection, snap-fit ​​connection, or interference fit, aiming to prevent axial displacement of the rotating shaft 219 during rotation.

[0036] In detail, this technical solution reliably fixes the rotatable connection between the module bracket 21 and the lamp holder 1 by introducing the end of the rotating shaft 219 into the housing 10 and constraining it with the shaft end limiting member 11. The design of the rotating shaft 219 extending from the outer wall of the module bracket 21 into the housing 10 not only provides operating space for the installation of the shaft end limiting member 11 but also effectively isolates the external environment from the rotatable connection. The housing 10, as a closed support structure, has a shaft hole 101 inside that precisely guides the movement trajectory of the rotating shaft 219, reducing rotational instability caused by eccentricity or wobbling. The connection method between the shaft end limiting member 11 and the end of the rotating shaft 219 ensures the reliability of axial limiting while avoiding the defects of external limiting methods being susceptible to interference or damage. The above designs work together to solve the axial displacement problem that may occur when the module bracket 21 is repeatedly rotated, ensuring the structural stability and operational safety of the wall lamp during angle adjustment.

[0037] like Figure 5 and Figure 9 As shown, this application further proposes that the outer periphery of the rotating shaft 219 is provided with an annular limiting groove 2191, and the housing 10 is provided with an annular boss 102 corresponding to the position of the annular limiting groove 2191, with the annular boss 102 extending into the annular limiting groove 2191.

[0038] Specifically, the annular limiting groove 2191 refers to a continuous annular channel formed on the outer circumference of the rotating shaft 219. The purpose of this structure is to provide a precise embedding space for the annular boss 102 on the housing 10, thereby effectively constraining the radial displacement range of the rotating shaft 219 and preventing vibration of the rotating shaft 219. The annular boss 102 can be understood as a ring-shaped structure extending axially along the housing 10 and penetrating deep into the annular limiting groove 2191. The purpose of this design is to distribute the axial load to the entire annular area through its cooperation with the annular limiting groove 2191, thereby enhancing the overall structure's vibration resistance.

[0039] In detail, this technical solution effectively restricts the axial displacement of the rotating shaft 219 through the cooperative design of the annular limiting groove 2191 and the annular boss 102. The annular limiting groove 2191 forms a continuous annular channel, providing a precise embedding space for the annular boss 102, ensuring that the axial and radial displacement of the rotating shaft 219 during rotation is physically constrained within the groove depth. The annular boss 102 on the housing 10 extends axially and penetrates deep into the annular limiting groove 2191, forming a radial support force through the contact between the boss and the sidewall of the groove, distributing the axial load to the entire annular area, rather than relying solely on the end point of the rotating shaft 219. This annular nested structure allows the rotating shaft 219 to rotate freely around its axis while strictly limiting the axial movement freedom, making the rotation smooth, stable, and free from axial wobble. Based on the aforementioned rotational connection requirements of the light-emitting module 2, this design significantly improves the accuracy of the wall lamp angle adjustment and the long-term reliability, solving the problem of shaft loosening caused by long-term rotation or external vibration.

[0040] This application further proposes that a damping pad 103 is provided between the bottom of the annular limiting groove 2191 and the annular boss 102.

[0041] Specifically, the damping pad 103 refers to a pad structure made of a material with elastic and frictional properties, which can be made of elastic materials such as rubber, silicone, or polyurethane. Its purpose is to reduce frictional resistance and noise during rotation by introducing an elastic material layer to avoid direct contact between metal parts, while also providing a certain damping force to prevent accidental rotation.

[0042] Because the annular boss 102 extends deep into the annular limiting groove 2191, the bottom contact surface is subjected to continuous friction and axial pressure during rotation. Therefore, the introduction of the damping pad 103 can significantly reduce rotational resistance, reduce wear and noise caused by friction, and make the wall lamp angle adjustment process smoother. In addition, the elastic material properties of the damping pad 103 provide controllable damping force, ensuring that the wall lamp will not rotate unexpectedly under gravity or slight external force, thereby maintaining the stability of the lighting direction and avoiding affecting the lighting effect or causing user discomfort due to angle deviation.

[0043] like Figure 10 As shown, this application further proposes that the outer periphery of the housing 10 corresponding to the shaft end limiting member 11 is provided with an annular baffle 105, and the outer wall of the shaft end limiting member 11 is fitted with a damping washer 106, and the damping washer 106 and the annular baffle 105 are squeezed together.

[0044] Specifically, the annular retaining wall 105 refers to the fixed support structure surrounding the outer periphery of the shaft end limiting member 11. It can be made of metal or high-strength plastic material and is achieved through injection molding or machining. The main purpose of this structure is to provide a stable extrusion interface for the damping washer 106, ensuring the uniformity of the damping effect.

[0045] In detail, this technical solution achieves controllable damping at the rotating connection of the wall lamp through the cooperation of the annular retaining wall 105 and the damping washer 106. The annular retaining wall 105 is precisely positioned on the outer periphery of the shaft end limiting member 11, ensuring that the squeezing force is concentrated on the outer periphery of the rotating shaft. During installation, the damping washer 106 fits tightly against the outer wall of the shaft end limiting member 11. When squeezed by the annular retaining wall 105, it will undergo radial deformation, increasing the friction coefficient of the contact surface. This structural design allows users to apply a reasonable torque for angle adjustment while preventing accidental slippage caused by slight external forces or gravity.

[0046] Furthermore, a first rotation limiting structure 107 is provided inside the shaft hole 101, and a second rotation limiting structure 117 is provided correspondingly for the shaft end limiting member 11. The first rotation limiting structure 107 limits the second rotation limiting structure 117 to limit the rotation range of the shaft end limiting member 11.

[0047] The first rotation limiting structure 107 can be a protruding edge extending around the outer periphery of the shaft hole 101. Its specific extension length can limit the rotation angle of the rotating shaft (i.e. the light-emitting module). For example, it can limit the light-emitting module to rotate 90° or 180°.
