Description

Technical Field

[0001] This utility model relates to the field of lamp holders, and in particular to an embedded lamp holder. Background Technology

[0002] A lamp bracket is a basic component in a lighting device that undertakes core functions such as structural support, electrical connection, and heat dissipation management. Its performance directly affects the installation stability, luminous output, service life, and safety of the lamp.

[0003] Lighting relies on light sources such as LED chips. These light sources generate a lot of heat when they are working. In existing technology, lighting fixtures mainly consist of a backplate and a front shell. The light source is installed in the backplate, and the front shell is installed at the opening of the backplate. The light emitted by the light source is emitted through the light-transmitting plate of the front shell. The heat is mainly released through the backplate on which the light source is installed. However, for recessed lighting fixtures, the heat dissipation of the backplate mainly depends on the internal environment of the embedded target. For example, in recessed lighting fixtures installed in the ceiling, the backplate is embedded inside the ceiling. The enclosed space and poor air circulation of the embedded environment will seriously affect the heat dissipation performance of the backplate, resulting in excessively high temperature of the light source, which will affect the luminous performance and lifespan of the lighting fixture. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an embedded lamp holder that can guide heat to the light-emitting side for release, resulting in high heat dissipation efficiency and effectively improving the luminous performance and lifespan of the applied lamp.

[0005] An embedded lamp holder according to an embodiment of the present utility model includes: The base has a mounting groove and a reflective cavity. The reflective cavity is bowl-shaped and connected to the bottom of the mounting groove. A wire hole is provided on one side of the mounting groove, and the cavity wall of the reflective cavity is coated with a reflective coating. The middle frame is located in the mounting groove and surrounds the bowl-shaped opening of the reflective cavity. The middle frame is provided with multiple heat-conducting core seats. Each heat-conducting core seat has multiple heat-conducting plugs on the side away from the reflective cavity. Each heat-conducting core seat has an emitting ramp on the side close to the reflective cavity. Each emitting ramp has multiple light source positioning slots for mounting light sources. The outer normal of the emitting ramp intersects with the reflective coating. The outer normal of each light source positioning slot at the bottom of the slot intersects with the reflective coating. The heat-conducting panel is connected to the base and is located on the side of the middle frame away from the reflective cavity. The center of the heat-conducting panel has a light-transmitting window facing the reflective cavity. One side of the heat-conducting panel has multiple heat-conducting slots that match the heat-conducting plugs. Each heat-conducting plug is inserted into the corresponding heat-conducting slot.

[0006] In this embodiment, a heat dissipation structure is provided on the side of the heat-conducting panel away from the reflective cavity, and the heat dissipation structure is located on the back of the heat-conducting slot.

[0007] In this embodiment, the heat dissipation structure includes multiple concentric annular protrusions, the middle frame is annular, and all the heat-conducting core seats are evenly distributed on the middle frame.

[0008] In this embodiment, the base has several heat dissipation fins on the side away from the heat-conducting panel.

[0009] In this embodiment, the curvature of the reflecting cavity gradually increases from the center outwards.

[0010] In this embodiment, a circular positioning sleeve is provided on the side of the base near the heat-conducting panel. The positioning sleeve surrounds the mounting groove. The outer wall of the positioning sleeve is provided with multiple longitudinal slots, each parallel to the rotation axis of the reflective cavity. Each longitudinal slot has a horizontal support groove connected to the end opposite to the heat-conducting panel. The horizontal support groove is perpendicular to the longitudinal slot. The side of the heat-conducting panel near the base is provided with multiple longitudinal rods distributed along a circumferential trajectory. The number of longitudinal rods is equal to the number of longitudinal slots. Each longitudinal rod is located outside the positioning sleeve. Each longitudinal rod has a positioning block matching the corresponding longitudinal slot at the end opposite to the heat-conducting panel. Each positioning block protrudes from the side of the longitudinal rod near the center of the heat-conducting panel and is located in the horizontal support groove.

[0011] In this embodiment, each positioning block has a hemispherical protrusion on the side near the heat-conducting panel, and each horizontal support groove has a hemispherical groove on the side near the heat-conducting panel, with the hemispherical protrusion located in the hemispherical groove.

[0012] In this embodiment, the base is provided with multiple fixing ear plates, and each fixing ear plate is provided with fixing screw holes.

[0013] The embodiments of this utility model have at least the following beneficial effects: A lighting system with a light source mounted on the side of a heat-conducting panel is constructed using an inclined luminous surface and a reflective coating on the reflective cavity. This system effectively utilizes the heat-conducting panel on the front to release heat into the open environment. Light emitted from the light source facing away from the heat-conducting panel is reflected and collected by the reflective coating before exiting through the luminous window, resulting in high light energy utilization. Furthermore, the reflective coating, laid along the bowl-shaped curved surface, effectively collects and reassembles light from various light sources, thereby significantly improving the uniformity of light emitted from the luminous window. The heat-conducting core holder supporting the light source is mounted against the heat-conducting panel, and the heat-conducting insert and slot effectively increase... The contact area between the heat-conducting core and the heat-conducting panel effectively improves the efficiency of heat energy diffusion and transfer from the heat-conducting core to the heat-conducting panel. The heat generated by the light source during operation can be efficiently transferred to the heat-conducting panel. The large-area heat-conducting panel can directly and efficiently release the heat diffused to various areas into the external air circulation environment, resulting in high heat dissipation efficiency. This effectively reduces the operating temperature of the supported light source, ensuring good performance of the supported light source and good luminous performance and long service life of the applied lamps. The modular design of the base, middle frame, and heat-conducting panel as the three main components effectively simplifies the installation and disassembly process, resulting in low maintenance costs.

[0020] A lamp bracket is a basic component in a lighting device that undertakes core functions such as structural support, electrical connection, and heat dissipation management. Its performance directly affects the installation stability, luminous output, service life, and safety of the lamp.

[0021] Lighting relies on LED chips and other light sources for illumination. These light sources generate a significant amount of heat during operation. In existing technologies, lighting fixtures mainly consist of a backplate and a front shell. The light source is installed in the backplate, and the front shell is installed at the opening of the backplate. The light emitted by the light source passes through the light-transmitting plate of the front shell, and the heat is mainly released through the backplate on which the light source is installed. This heat dissipation path is singular and limited. For recessed lighting fixtures, the heat dissipation of the backplate mainly depends on the internal environment of the embedded target. For example, in recessed lighting fixtures installed in the ceiling, the backplate is embedded inside the ceiling. The enclosed space and poor air circulation of the embedded environment will seriously affect the heat dissipation performance of the backplate, leading to excessively high temperatures of the light source. This can induce problems such as luminous efficacy decay, color temperature drift, and shortened lifespan, affecting the luminous performance and lifespan of the lighting fixture.

[0022] In related technologies, a common approach to solve the heat dissipation problem is to combine the lamp bracket with an additional heat sink, such as adding heat dissipation fins to the back of the bracket. However, this improved structure has inherent defects: its heat dissipation path is mainly towards the back of the lamp, i.e. the mounting surface, such as the ceiling or the inside of the wall. For recessed lamps, the space behind is usually sealed and has poor air circulation, which seriously limits the heat dissipation efficiency and also has the aforementioned heat dissipation bottleneck.

[0023] The following is for reference only. Figure 1 To be continued Figure 7 The embedded lamp holder described in this utility model can guide heat to the light-emitting side, i.e., the outside, for release, resulting in high heat dissipation efficiency and effectively improving the luminous performance and service life of the applied lamp.

[0024] Reference Figures 1 to 7 An embedded lamp holder according to an embodiment of the present invention includes: The base 100 has a mounting groove 110 and a reflective cavity 120. The base 100 serves as the back structure of the lamp. The reflective cavity 120 is bowl-shaped and connected to the bottom of the mounting groove 110. Specifically, the bowl-shaped opening of the reflective cavity 120 is located at the center of the bottom of the mounting groove 110 to achieve communication between the mounting groove 110 and the reflective cavity 120. The shape of the reflective cavity 120 matches the outer contour of the rotating body. The generatrix of the rotating body can be a parabola or other curves. The generatrix of the rotating body can be set according to the actual lighting requirements. A wire hole 111 is provided on one side of the mounting groove 110. The wire hole 111 is used to pass a conductive wire to ensure that the light source inside the lamp can be connected to the external power supply. The cavity wall of the reflective cavity 120 is provided with a reflective coating 121. The reflective coating 121 can be a coating made of reflective materials such as aluminum or silver, which has a good reflective effect on visible light. A middle frame 200 is disposed in the mounting groove 110. The middle frame 200 surrounds the bowl-shaped opening of the reflective cavity 120 to ensure that the bowl-shaped opening of the reflective cavity 120 is unobstructed, thereby improving the light emission efficiency of the bowl-shaped opening of the reflective cavity 120. The middle frame 200 has multiple evenly distributed heat-conducting core seats 210. Each heat-conducting core seat 210 has multiple heat-conducting inserts 211 on the side away from the reflective cavity 120. Each heat-conducting core seat 210 has an emission slope 212 on the side close to the reflective cavity 120. The inclined surfaces are tilted relative to the rotation axis of the reflective cavity 120. Each emitting inclined surface 212 is provided with multiple light source positioning slots 213 for mounting the light source. Preferably, the light source positioning slots 213 are evenly distributed in an array on the emitting inclined surface 212. The light source can be a positively mounted LED chip. After the light source is mounted in the light source positioning slot 213, the electrode on the light-emitting surface side of the light source is connected to an external power supply via a conductive wire passing through a wire hole 111. The outer normal of the emitting inclined surface 212 is perpendicular to the reflective coating 121. The intersecting outer normal refers to the vector line pointing from the inside of the heat-conducting core seat 210 to the outside and perpendicular to the emitting slope 212. The bottom of the light source positioning groove 213 is parallel to the emitting slope 212 to ensure that the optical axis of the light source is parallel to the outer normal of the emitting slope 212. The outer normal of each light source positioning groove 213 at the bottom of the groove intersects with the reflective coating 121. The groove wall of the light source positioning groove 213 is perpendicular to the groove bottom. By unifying the direction of the emitting slope 212 and the bottom of the light source positioning groove 213, the light emitted by the light source can be avoided from being lost due to the groove wall of the light source positioning groove 213, and the effective utilization rate of the light emitted by the light source can be improved. When the light emitted by the light source enters the reflective cavity 120 through the bottom of the mounting groove 110 and reaches the reflective coating 121, it is reflected to the groove opening of the mounting groove 110 and emitted. After the light source is installed in the light source positioning groove 213, the heat generated by the light source during operation can be released towards the front of the lamp through the heat-conducting core seat 210 and the heat-conducting plug 211. A heat-conducting panel 300 is detachably connected to the base 100. The heat-conducting panel 300 is located on the side of the middle frame 200 facing away from the reflector cavity 120, meaning it is installed as the front structure of the lamp. A light-transmitting window 310 is located at the center of the heat-conducting panel 300, directly opposite the reflector cavity 120. The light-transmitting window 310 is a through-hole structure located at the center of the heat-conducting panel 300. Depending on the actual application requirements, a light-transmitting material such as a glass plate or acrylic plate can be glued to the light-transmitting window 310. The central axis of the light-transmitting window 310 is collinear with the rotation axis of the reflector cavity 120. The plate 300 has multiple heat-conducting slots 320 on the side near the reflective cavity 120, each matching a heat-conducting plug 211. The number of heat-conducting slots 320 is equal to the number of heat-conducting plugs 211. That is, the position, shape and size of each heat-conducting slot 320 correspond one-to-one with the corresponding heat-conducting plug 211. Each heat-conducting plug 211 is inserted into the corresponding heat-conducting slot 320, and the outer wall of the heat-conducting plug 211 abuts against the inner wall of the heat-conducting slot 320 to ensure heat conduction efficiency. The heat-conducting core seat 210 and the heat-conducting panel 300 are structural components made of materials with high thermal conductivity, such as aluminum alloy.

[0025] When in use, the base 100 is fixedly installed on the target body of the application scenario. When disassembling, the heat-conducting panel 300 is removed from the base 100. Due to the positioning of the heat-conducting plug 211 and the heat-conducting slot 320, the middle frame 200 and its connected heat-conducting core seat 210 are separated from the base 100 along with the heat-conducting panel 300. As needed, the internal parts of the recessed lamp can be maintained, or the middle frame 200, the heat-conducting core seat 210 and the light source installed on it can be replaced. The base 100 and the panel can remain usable, and the installation of the base 100 remains unchanged. This simplifies the disassembly and assembly steps, makes replacement and maintenance convenient, and replacement only requires the middle frame 200 and its associated structure. It is environmentally friendly and energy-saving, and can effectively reduce application costs.

[0026] During operation, the light emitted by the light source shines onto the reflective coating 121 of the reflective cavity 120. The light is reflected by the reflective coating 121 and exits through the light-transmitting window 310, so that the embedded lamp ultimately emits light from the base 100 toward the heat-conducting panel 300. The heat generated by the light source during operation is transferred to the heat-conducting panel 300 through the heat-conducting core seat 210 via the cooperation of the heat-conducting plug 211 and the heat-conducting slot 320. This allows most of the heat generated by the light source during operation to be released from the side of the heat-conducting panel 300 away from the base 100. In other words, the embedded lamp bracket can dissipate heat from the light-emitting surface, i.e., the front, and the high-velocity airflow in the external environment can help improve the heat dissipation performance of the embedded lamp.

[0027] By using an inclined light-emitting slope in conjunction with a reflective coating 121 attached to the bowl-shaped reflective cavity 120, a lighting system with the light source mounted on the side of the heat-conducting panel 300 is constructed. This effectively utilizes the heat-conducting panel 300 located on the front to release heat into the open environment, overcoming the limitations of traditional methods that only allow heat dissipation in the enclosed, poorly ventilated space embedded within the light source. This also breaks through the heat dissipation bottleneck of existing embedded lighting technologies. The light emitted by the light source is reflected and collected by the reflective coating 121 and emitted through the light-emitting window, meaning the light ultimately travels along the bottom... The light emitted from the heat-conducting core 210 towards the heat-conducting panel 300 has a high utilization rate of light energy. Furthermore, the reflective coating 121, laid along the bowl-shaped curved surface, effectively collects and reassembles light from various light sources, thereby significantly improving the uniformity of light emitted from the light-emitting window. The heat-conducting core 210, which carries the light source, is mounted against the heat-conducting panel 300. The heat-conducting insert 211 and heat-conducting slot 320 effectively increase the contact area between the heat-conducting core 210 and the heat-conducting panel 300, effectively improving the diffusion and transfer of heat energy from the heat-conducting core 210 to the heat-conducting surface. The heat generated by the light source during operation is efficiently transferred to the heat-conducting panel 300. The panel is positioned on the front of the embedded luminaire and directly contacts the open, well-ventilated environment. The large-area heat-conducting panel 300 efficiently releases heat diffused to various areas into the air, resulting in high heat dissipation efficiency and effectively reducing the operating temperature of the light source. Specifically, it effectively reduces luminous efficacy decay and color temperature drift, thereby improving the luminous performance and lifespan of the luminaire. The modular design of the base 100, middle frame 200, and heat-conducting panel 300 simplifies installation and disassembly, making installation and use convenient and reducing costs. The base 100 is fixed to the embedded target. After opening the heat-conducting panel 300, the middle frame 200 can be installed and removed via plug-and-play with the help of the heat-conducting insert 211 and heat-conducting slot 320. Maintenance and replacement are convenient and cost-effective, as most maintenance and replacement work is concentrated on the middle frame 200, which supports the light source. The modular design facilitates easy maintenance and replacement.

[0028] By rationally separating the conductive lines from the high-temperature heat dissipation areas through a structural layout, the risk of wire aging and damage due to long-term heat exposure can be effectively reduced. At the same time, the robust mechanical structure and efficient heat dissipation capacity jointly ensure the stability and safety of the applied lamps during long-term use. By setting mounting bevels or positioning slots with precise angles, the bracket can efficiently conduct heat away while ensuring that the optical axis of each light source is precisely pointed to the preset reflective or refractive optical element. This integrated design solves the problem of integrating the optical paths of multiple light sources, and can produce a uniform, soft, stray light-free high-quality light spot. At the same time, it achieves extreme compactness of the structure, making it possible to design a thin and light-weight lamp.

[0029] Understandably, a heat dissipation structure 330 is provided on the side of the heat-conducting panel 300 facing away from the reflective cavity 120. The heat dissipation structure 330 is located on the back of the heat-conducting slot 320, that is, projected along the rotation axis of the reflective cavity 120. The projection of the heat dissipation structure 330 intersects with the projection of the heat-conducting slot 320. A precise vertical heat dissipation path is formed by the heat-conducting core 210, the heat-conducting panel 300, and the heat dissipation structure 330. Heat is emitted from the light source and is transferred directly to the corresponding heat dissipation structure 330 on the heat-conducting panel 300 through the heat-conducting core 210 and the heat-conducting plug 211.

[0030] The projection of the heat dissipation structure 330 intersects with the projection of the heat conduction slot 320, meaning that the heat dissipation body is directly facing the internal heat input point, establishing a short and direct heat conduction channel, which greatly reduces the thermal resistance of the entire heat transfer path. When this recessed lighting fixture bracket is embedded in the indoor ceiling, this downward-facing heat dissipation structure 330 is completely exposed to the indoor air, not restricted by the enclosed space inside the ceiling. It can utilize the natural convection of hot and cold air to achieve efficient forward active heat dissipation, fundamentally improving the heat dissipation problem of recessed lighting fixtures.

[0031] It is understood that the heat dissipation structure 330 includes multiple concentric annular protrusions, the middle frame 200 is annular, and all the heat-conducting core seats 210 are evenly distributed on the middle frame 200. The multiple concentric annular protrusions can effectively increase the contact area between the heat-conducting panel 300 and the ambient air, thereby effectively increasing the heat dissipation. The heat-conducting core seats 210 with high thermal conductivity can efficiently and quickly diffuse the heat generated when the light source is working to all areas of the heat-conducting panel 300. At the same time, the multiple concentric annular protrusions increase the heat exchange efficiency between the heat-conducting panel 300 and the external environment, thereby significantly improving the heat dissipation effect of the light source and improving the heat dissipation performance of the recessed lamp during operation. The heat-conducting slots 320 and the heat dissipation structure 330 respectively located on the front and back of the heat-conducting panel 300 can effectively shorten the heat release path, thereby further improving the heat dissipation efficiency.

[0032] In addition, the circular protrusions have less obstruction to airflow and can guide hot air to rise and diffuse naturally along the gaps between the rings, forming a more orderly chimney effect and enhancing the convective heat transfer efficiency. While increasing the surface area, the circular protrusions also act as reinforcing ribs, enhancing the deformation resistance of the heat-conducting panel 300. Furthermore, the appearance is simple and beautiful, meeting the industrial design requirements of modern lighting fixtures.

[0033] It is understandable that the base 100 has several heat dissipation fins 130 on the side away from the heat-conducting panel 300. The heat dissipation fins 130 can effectively improve the heat exchange efficiency between the base 100 and the internal environment of the target into which the lamp is embedded, that is, improve the heat dissipation efficiency of the back side of the embedded lamp. Combined with the bidirectional heat dissipation system of the heat-conducting panel 300 on the front, the overall heat dissipation efficiency of the embedded lamp can be effectively improved.

[0034] When the applied lighting fixture is working, the heat is quickly released through the front heat-conducting panel 300, and can also diffuse into the interior of the embedded target such as the ceiling through the fins on the back of the base 100, realizing dual-path heat dissipation, which significantly improves the redundancy and reliability of heat dissipation capacity, and is especially suitable for harsh scenarios with high power or long-term continuous operation.

[0035] Understandably, the curvature of the reflective cavity 120 gradually increases from the center outwards, effectively improving its light-gathering effect and thus increasing energy utilization. By optimizing the curvature of the reflective cavity 120 into an aspherical or composite surface, compared to a simple parabola or sphere, this gradual curvature design can more precisely control the light reflection path. The curved reflective coating 121 in the lamp holder can more evenly and efficiently collect and guide light from different light sources to the light-transmitting window 310. The specific curvature can be determined according to the actual lighting application requirements based on conventional optical design.

[0036] Understandably, the base 100 has a ring-shaped positioning sleeve 140 on the side near the heat-conducting panel 300. The positioning sleeve 140 surrounds the mounting groove 110. The outer wall of the positioning sleeve 140 has multiple vertical slots 141, all parallel to the rotation axis of the reflective cavity 120. Each vertical slot 141 has a horizontal support groove 142 connected to one end away from the heat-conducting panel 300. The other end of each vertical slot 141 passes through the surface of the positioning sleeve 140 near the heat-conducting panel 300 for insertion and clearance. The horizontal support groove 142 is perpendicular to the vertical slot 141. The heat-conducting panel 300 has multiple vertical rods 340 distributed along a circumferential trajectory on the side near the base 100. The number of vertical rods 340 is equal to the number of vertical slots 141. Each vertical rod 340 is located outside the positioning sleeve 140, that is, each vertical rod 340 surrounds the positioning sleeve. Around the perimeter of 140, each vertical rod 340 has a positioning block 350 at the end opposite to the heat-conducting panel 300 that matches the corresponding vertical slot 141. Each positioning block 350 protrudes from the side of the vertical rod 340 near the center of the heat-conducting panel 300. The positioning block 350 is located in the horizontal support groove 142. During installation, align the positioning block 350 with the vertical slot 141 until the positioning block 350 reaches the end of the vertical slot 141. Rotate the heat-conducting panel 300 to insert the positioning block 350 into the horizontal support groove 142. The installation operation is convenient. Furthermore, the staggered vertical slots 141 and horizontal support grooves 142 ensure that the installation direction and the positioning force direction are in different dimensions, which can effectively improve the stability of the installation positioning effect. Disassembly can be carried out in the reverse order. It is easy to use and can be effectively adapted for embedding in indoor ceilings.

[0037] Assembly requires only three simple actions: alignment, insertion, and rotation, greatly improving production efficiency and the convenience of on-site installation and maintenance. By combining longitudinal insertion movement with lateral rotation locking, the force direction at the connection point is perpendicular to the possible direction of detachment, effectively resisting vibration and ensuring the stability of the connection during long-term use, preventing the lamp from loosening due to its own weight or external forces. All connecting components are arranged around the outer periphery of the optical components, resulting in a compact structure that effectively avoids the space of the core optical and heat dissipation channels, demonstrating a rational structural layout.

[0038] It is understood that each positioning block 350 has a hemispherical protrusion 351 on the side near the heat-conducting panel 300. The hemispherical protrusion 351 is a hemispherical protrusion structure. Each horizontal support groove 142 has a hemispherical groove 143 matching the hemispherical protrusion 351 on the side near the heat-conducting panel 300. The hemispherical groove 143 is a hemispherical groove structure. The hemispherical protrusion 351 is located in the hemispherical groove 143. The hemispherical protrusion 351 and the hemispherical groove 143 can effectively improve the stability of the structure when the positioning block 350 is installed in the horizontal support groove 142, so as to improve the stability of the installation positioning structure between the heat-conducting panel 300 and the base 100 from multiple dimensions.

[0039] When the heat-conducting panel 300 is rotated to the correct installation position, the hemispherical protrusion 351 slides into the hemispherical groove 143. The operator will feel a clear "click" sound or a change in resistance, providing a clear signal that the installation is in place and effectively preventing improper installation or excessive rotation. The engagement between the hemispherical protrusion 351 and the hemispherical groove 143 forms a small mechanical locking point, requiring a certain torque to disengage. This effectively prevents the connection structure from loosening due to thermal expansion and contraction caused by slight vibrations or temperature changes, further improving the long-term stability of the connection. The friction between the hemispherical protrusion 351 and the hemispherical groove 143 is low, and when maintenance is required, it can be easily unlocked by applying an appropriate reverse torque, achieving a balance between stability and maintainability.

[0040] It is understood that the base 100 is provided with multiple fixing ear plates 150, each fixing ear plate 150 is provided with fixing screw holes 151. During installation, the base 100 is fixedly installed to the object to be used by screws engaging with the fixing screw holes 151.

[0041] The fixed ear plate 150 serves as a connecting bridge between the base 100 and embedded targets such as ceiling joists. By setting screw holes, it is compatible with common installation methods. The evenly distributed design of multiple ear plates ensures uniform force distribution and structural stability during installation.
