Description

[0002] The existing lighting lamps and lanterns not only pursue high efficient optical performance, but also pay more and more attention to the balance of heat dissipation efficiency and structural compactness. However, the existing lighting lamps and lanterns design, especially small lamps such as cylinder spotlight, usually fixes the heat dissipation module in the inside of the lamp body. When the lamp selects high power, it needs to reserve larger installation space for the heat dissipation module, which will greatly increase the volume of the lighting lamps and lanterns. This is contrary to the miniaturization trend pursued by modern lighting design.

The power of small lamps is generally low, which cannot meet the needs of places such as commercial display, stage lighting, high-end home decoration and other high-power requirements.

[0033] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be described in detail below with reference to the drawings and specific embodiments.

[0034] Here, it should be noted that, in order to avoid the unnecessary details from blurring the present application, only the structures and / or processing steps closely related to the scheme of the present application are shown in the drawings, and other details not closely related to the present application are omitted.

[0035] ​It is also important to note that the term "comprising" or "including" or any other variation thereof is intended to cover a non-exclusive inclusion, such that processes, methods, articles, or apparatuses that comprise a list of elements are not required to comprise only those elements but can include other elements not expressly listed or inherent to such processes, methods, articles, or apparatuses.

[0036] Referring to Figures 1 to 9 As shown in the drawings, the embodiment of the utility model provides a lamp 100, the lamp 100 is the illumination product such as down lamp, spotlight etc. Lamp 100 includes lamp body 1 and heat dissipation assembly 2, heat dissipation assembly 2 is connected with lamp body 1, and lamp body 1 is cooled through heat dissipation assembly 2.

[0037] Referring to Figure 1 As shown in the drawings, lamp body 1 includes lighting side 11 and the drive part 12 set up in the back of lighting side 11. Lamp body 1 is equipped with light source module 3 in lighting side 11, and drive part 12 is equipped with built-in power supply (not shown). Built-in power supply supplies power for light source module 3, and the light emitted by light source module 3 is emitted from lighting side 11.

[0038] Referring to Figures 1 to 3 As shown in the drawings, drive part 12 includes top cover 121 and gland 122 set up in the side of top cover 121 away from lighting side 11. Top cover 121 and gland 122 are assembled and fixed mutually, and are equipped with heat dissipation channel 123 between the two. Lamp 100 in the working process, drive part 12 will produce a large amount of heat, and the heat can be dissipated to the external environment through heat dissipation channel 123, to keep the normal working temperature inside lamp 100.

[0039] Referring to Figure 4 As shown in the drawings, in this embodiment, top cover 121 is equipped with a positioning column 1211, and top cover 121 is fixedly connected with heat dissipation assembly 2 through positioning column 1211. In other embodiments, top cover 121 can be equipped with multiple positioning columns 1211.

[0040] In some embodiments, top cover 121 is equipped with a positioning hole 213, and top cover 121 is fixedly connected with heat dissipation assembly 2 through positioning hole 213. In other embodiments, top cover 121 can be equipped with multiple positioning holes 213.

[0041] In some embodiments, the heat dissipation assembly 2 and the top cover 121 are movably connected. The grommet 122 is provided with an elastic abutting piece 124 on the side facing the top cover 121. One end of the elastic abutting piece 124 is in abutment with the grommet 122, and the other end is in abutment with the heat dissipation assembly 2, so that the heat dissipation assembly 2 can be positioned in a fixed position without external force. When it is necessary to adjust the position of the heat dissipation assembly 2, an appropriate external force is applied to the heat dissipation assembly 2, so that the heat dissipation assembly 2 presses the elastic abutting piece 124 upward, the elastic abutting piece 124 is pressed, and in turn deforms. With the increase of deformation, the elastic abutting piece 124 is no longer in abutment with the heat dissipation assembly 2, thereby releasing the positioning of the heat dissipation assembly 2. At this time, the heat dissipation assembly 2 can move freely within a certain range to meet the adjustment requirement.

[0042] Preferably, under the action of external force, the middle part of the heat dissipation assembly 2 is moved to the heat source dense place of the lamp body 1, so that the areas on both sides of the heat source dense place of the heat dissipation assembly 2 are equal, which promotes the uniform distribution and rapid conduction of heat, and maximizes the heat dissipation efficiency of the heat dissipation assembly 2. By simply adjusting the position of the heat dissipation assembly 2, the heat dissipation effect is optimized, which can be flexibly adjusted according to different use scenarios and requirements.

[0043] In some embodiments, the elastic abutting piece 124 is a spring, and in other embodiments, the elastic abutting piece 124 can also be other elastic elements capable of producing elastic deformation, which are not limited here.

[0044] The heat dissipation assembly 2 is arranged at the top of the lamp body 1 and is flexible, and can be bent to a certain extent. When the lamp 100 is fixedly installed on the installation base, such as the ceiling, the heat dissipation assembly 2 can be bent and deformed to a certain extent, so that the heat dissipation assembly 2 can easily adapt to installation openings of different shapes and sizes, greatly improving the flexibility and convenience of installation.

[0045] Please refer to Figure 1 and Figure 5 , the heat dissipation assembly 2 includes a flexible heat dissipation body 21 and two fixing pieces 22 arranged at both ends of the flexible heat dissipation body 21. In this embodiment, the flexible heat dissipation body 21 is a flexible heat dissipation sheet. The flexible heat dissipation body 21 penetrates the heat dissipation channel 123 and is attached to the top cover 121, so that the lamp 100 can dissipate heat through both sides of the flexible heat dissipation body 21 at the same time, which can greatly improve the heat dissipation efficiency of the lamp 100. Such arrangement enables the lamp 100 to maintain stable temperature during high-power operation, effectively prolonging the service life of the lamp 100. In the case of retaining the compact appearance structure of the lamp 100, the heat dissipation efficiency of the lamp 100 is enhanced, which can solve the problem of heat dissipation failure of the lamp 100 during high-power operation.

[0046] The length of the flexible heat dissipation body 21 can be adjusted according to the specific power requirement of the lamp 100. When the power of the lamp 100 is increased, the length of the flexible heat dissipation body 21 is appropriately increased to increase the heat dissipation area, thereby improving the heat dissipation performance. The lamp 100 can realize higher power output and better heat dissipation effect without sacrificing the volume and appearance, to meet the market demand for high luminous flux.

[0047] The two fixing members 22 are respectively located on both sides of the heat dissipation channel 123 to increase the structural strength of the flexible heat dissipation body 21, prevent the two ends of the flexible heat dissipation body 21 from curling, and ensure the overall aesthetics of the lamp 100.

[0048] In the embodiment, the fixing member 22 is a decorative end head with a long slot, and the flexible heat dissipation body 21 is pressed tightly by the riveting groove, so that the flexible heat dissipation body 21 is fixedly connected with the decorative end head. The fixing member 22 is exposed to the heat dissipation channel 123, and the flexible heat dissipation body 21 can maintain a flat state after installation through the support of the fixing member 22. Therefore, compared with the curled flexible heat dissipation body 21, the heat dissipation area is increased, and the lamp body 1 is facilitated to quickly dissipate heat through the flexible heat dissipation body 21.

[0049] The flexible heat dissipation body 21 includes a first area 211 located below the top cover 121 and a second area 212 located on both sides of the first area 211. The heat generated by the driving part 12 is mainly concentrated near the top cover 121, the first area 211 is attached to the top cover 121, and the first area 211 can quickly and effectively absorb and conduct most of the heat.

[0050] In some preferred embodiments, the first area 211 is made of a first material, and the second area 212 is made of a second material. The heat dissipation coefficient of the first material is higher than that of the second material. The first material includes but is not limited to copper, graphene and other fast heat dissipation materials, and the second material includes but is not limited to aluminum, carbon fiber and other heat dissipation materials.

[0051] The first area 211 where heat is concentrated adopts a high-efficiency heat dissipation material, realizes rapid conduction and preliminary dispersion of heat, and ensures that heat can be conducted from the heat source to the heat dissipation body in the first time. The heat retention and accumulation in the lamp body 1 are effectively reduced to realize rapid heat dissipation. Moreover, the two second areas 212 respectively located on both sides of the first area 211 are symmetrical in structure to evenly expand the heat dissipation area, avoid local accumulation or overheating of the heat generated by the lamp 100, and ensure that the components of the lamp 100 work in an appropriate temperature range.

[0052] In some embodiments, the flexible heat dissipation body 21 can be made of the first material throughout.

[0053] In other embodiments, the lamp 100 has a lower power and the driving unit 12 generates less heat, the flexible heat dissipation body 21 can be made of the second material throughout. It can be understood that the selection of the material for preparing the flexible heat dissipation body 21 is usually determined in association with the output power of the lamp to which the flexible heat dissipation body 21 is applied.

[0054] Specifically, the flexible heat dissipation body 21 can be made of any one or more of metal materials such as aluminum and copper. Alternatively, the flexible heat dissipation body 21 can also be made of any one or more of non-metal materials such as carbon fiber and graphene. For example, the surface of the flexible heat dissipation body 21 is anodized to form an oxide film or is provided with one or more graphene coatings. The graphene coating is preferred. Graphene material has excellent heat conduction performance and flexibility, which can improve the heat dissipation capacity while meeting the requirements of flexible materials.

[0055] In some preferred embodiments, the flexible heat dissipation body 21 can be made of a composite material containing metal materials and non-metal materials.

[0056] Referring to FIG. 1, Figures 6 to 7 As shown, the flexible heat dissipation body 21 can be prepared by weaving, stacking multiple pieces, and filling with filaments. Preferably, the flexible heat dissipation body 21 is made of a filament material, which can integrate different materials and structures together.

[0057] In other embodiments, the flexible heat dissipation body 21 is prepared by stacking sheet materials, fixing different materials together by colloid, and forming a multi-layer composite structure.

[0058] Referring to FIG. 1, Figure 8 As shown, in some embodiments, the flexible heat dissipation body 21 is provided with any one of a porous structure, a mesh structure, and a strip structure. In other embodiments, the flexible heat dissipation body 21 is provided with a plurality of combined structures of the porous structure, the mesh structure, and the strip structure.

[0059] In some embodiments, the flexible heat dissipation body 21 is a single-layer structure, which can be any one of a porous structure, a mesh structure, and a strip structure or a plurality of combined structures. When the flexible heat dissipation body 21 is a plurality of combined structures, it is usually prepared by weaving.

[0060] In other embodiments, the flexible heat dissipation body 21 can adopt a multi-layer composite structure. The multi-layer composite structure can be any one of a porous structure, a mesh structure, and a strip structure, or a plurality of combined structures of the porous structure, the mesh structure, and the strip structure.

[0061] The flexible heat dissipation body 21 is provided with at least one positioning hole 213 corresponding to the positioning column 1211. The top cover 121 and the flexible heat dissipation body 21 are connected through the positioning column 1211 and the positioning hole 213 to fix the flexible heat dissipation body 21 between the top cover 121 and the gland 122.

[0062] When the heat source of the lamp body 1 is mainly concentrated in the middle part of the lamp body 1, the positioning column 1211 is fixed in the middle part of the top cover 121, i.e. the heat source dense place. The positioning hole 213 is arranged in the middle part of the flexible heat dissipation body 21, and the flexible heat dissipation body 21 is fixed in the middle part of the top cover 121 by passing the positioning column 1211 through the positioning hole 213, so that the flexible heat dissipation body 21 can directly absorb the heat generated by the lamp body 1. And, the area of the flexible heat dissipation body 21 on both sides of the positioning column 1211 is equal, which is beneficial to the uniform distribution and rapid conduction of heat on the heat dissipation body, and improves the heat dissipation efficiency. Avoid the local overheating phenomenon caused by uneven heat dissipation area, further improve the heat dissipation efficiency.

[0063] In other embodiments, the flexible heat dissipation body 21 is provided with a plurality of positioning holes 213, which can be selectively fixed and connected with the positioning column 1211 according to needs to fix the flexible heat dissipation body 21 at the best heat dissipation position of the lamp body 1. Usually, the middle part of the flexible heat dissipation body 21 is fixed at the heat source dense place of the lamp body 1, which ensures that the heat dissipation body can directly and effectively absorb and conduct a large amount of heat generated in the heat source dense area, and improves the heat dissipation efficiency. Due to the flexible fixing configuration of the positioning hole 213 and the positioning column 1211, the flexible heat dissipation body 21 can adapt to the needs of lamps 100 of different shapes, sizes and powers.

[0064] For example, when the lamp 100 is a special-shaped lamp, the heat source of the lamp 100 is mainly concentrated on the left side, and the positioning column 1211 is arranged in the middle part of the top cover 121. By passing the positioning hole 213 on the right side of the flexible heat dissipation body 21 through the positioning column 1211, the area of the flexible heat dissipation body 21 on both sides of the heat source dense place is equal to ensure the heat dissipation efficiency. If the heat source of the lamp 100 is mainly concentrated on the left side, the positioning column 1211 is also arranged on the left side of the top cover 121 at the heat source dense place. By passing the positioning hole 213 in the middle part of the flexible heat dissipation body 21 through the positioning column 1211, the area of the flexible heat dissipation body 21 on both sides of the positioning column 1211 is equal to ensure the heat dissipation efficiency.

[0065] In some preferred embodiments, the flexible heat dissipation body 21 is provided with a plurality of positioning holes 213, and the ratio of the total area of the plurality of positioning holes 213 to the area of the flexible heat dissipation body 21 is less than 0.2. By limiting the proportion of the positioning holes 213, the structure of the flexible heat dissipation body 21 is not damaged, and the heat dissipation function of the flexible heat dissipation body 21 is not affected. Moreover, the reasonable distribution of the plurality of positioning holes 213 can not only serve as fixing points, but also can optimize the heat conduction path inside the flexible heat dissipation body 21 to a certain extent. By reducing the local thermal resistance, heat can be more smoothly spread from the heat source area to the surrounding, further improving the heat dissipation efficiency.

[0066] Referring to Figure 9 As shown in the drawings, in order to further improve the heat dissipation capacity of the lamp 100, the lamp 100 is provided with a plurality of heat dissipation assemblies 2 for further increasing the heat dissipation area and improving the heat dissipation efficiency. The flexible heat dissipation body 21 of each of the plurality of heat dissipation assemblies 2 passes through the heat dissipation channel 123, so that the heat generated by the lamp 100 during operation can be quickly dissipated to the surrounding environment through the heat dissipation channel 123. The fixing member 22 of each of the plurality of heat dissipation assemblies 2 is located outside the heat dissipation channel 123, and the flexible heat dissipation body 21 can maintain a flat state for heat dissipation after installation by arranging the fixing member 22.

[0067] In some preferred embodiments, the plurality of flexible heat dissipation bodies 21 at least partially overlap, and the plurality of flexible heat dissipation bodies 21 are made of different materials. The flexible heat dissipation body 21 close to the top cover 121 is made of a first material with a higher heat dissipation coefficient, which can quickly conduct heat away from the high-temperature area and achieve rapid cooling. The flexible heat dissipation body 21 away from the top cover 121 can be made of a second material with a lower heat dissipation coefficient, which can optimize the material cost while ensuring the overall heat dissipation effect. This layered design enables efficient heat transfer and dissipation according to the differences in material properties.

[0068] In some preferred embodiments, the plurality of flexible heat dissipation bodies 21 at least partially overlap, and the plurality of flexible heat dissipation bodies 21 adopt different structures. Without affecting the heat dissipation function, the flexible heat dissipation body 21 away from the top cover 121 can adopt a more beautiful heat dissipation structure to enhance the visual appeal of the lamp 100.

[0069] In summary, the flexible heat dissipation body 21 penetrates the heat dissipation channel 123 and is closely attached to the top cover 121, ensuring that the heat generated by the driving part 12 can be rapidly and effectively conducted to both sides of the flexible heat dissipation body 21, and then dissipated to the external environment. Both sides of the heat dissipation channel 123 are simultaneously cooled by the flexible heat dissipation body 21, making the heat dispersion more uniform and improving the heat dissipation performance of the lamp 100. The bilateral heat dissipation mechanism of the lamp 100 not only accelerates the heat dissipation, but also avoids the occurrence of local overheating, providing a solid guarantee for the stable operation of the lamp 100. The two ends of the flexible heat dissipation body 21 are respectively provided with two fixing members 22, which provide stable support for the flexible heat dissipation body 21, prevent it from curling or deforming under external force, and enhance the structural strength of the entire heat dissipation assembly 2. This design also ensures that the flexible heat dissipation body 21 can maintain a straight state, and the heat dissipation in a straight state compared to the heat dissipation in a curled state increases the heat contact area, thereby improving the heat dissipation efficiency. Thus, the lamp 100 can have higher heat dissipation efficiency while maintaining a compact structure. Compared with the prior art, the lamp 100 of the present application can adjust the heat dissipation assembly 2 according to the requirements without changing the overall volume of the lighting lamp 100, to adapt to the heat dissipation requirements of different power lamps 100.

[0070] The above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
