Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of lighting devices, specifically relating to a side-emitting lamp body structure and a panel lamp. Background Technology
[0002] Panel lights, as basic lighting equipment for large spaces, are widely used in offices, factories, and warehouses. Among panel lights, side lighting, which uses light-emitting elements positioned on the side of the frame, is one of the mainstream solutions.
[0003] However, side-mounted light-emitting elements have lower heat dissipation efficiency compared to those mounted on the top back panel. Furthermore, during the heat generation process, the light guide plate and other optical components expand due to temperature rise, compressing the light-emitting elements and causing damage to the elements and deformation of the panel light structure, severely impacting the panel light's lifespan. Additionally, the increased distance between the light guide plate and the light-emitting elements, along with irreversible deformation of the optical components due to compression, leads to reduced light output and luminous efficacy in subsequent panel lights.
[0004] While existing solutions address some heat dissipation or deformation issues, the extent of the solution is limited and they are not applicable to most panel light applications. Furthermore, existing solutions all increase the complexity of the panel light manufacturing process and raise manufacturing costs. Summary of the Invention

By cleverly placing the first elastic element, the light source assembly, and the first heat dissipation part in the mounting groove, the heat dissipation efficiency is improved, while also preventing the light source assembly from being damaged by the optical assembly, thereby extending its service life and making its light output effect more stable.
[0006] The technical effect to be achieved by this utility model is realized through the following technical solution:

[0018] In some implementations, the reflector portion is attached to the second heat dissipation portion, and the reflector portion is connected to the back plate via the second elastic portion.
[0019] In some implementations, fasteners are also included. The frame strip is made of iron. Multiple frame strips are fixed together by laser melting to form a face frame.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0050] Example 1:
[0051] Please see Figures 1-3 This embodiment provides a side-emitting lamp body structure 100, including a face frame 1, an optical component 2, a heat sink 3, a light source component 4, and a buffer component 5. The face frame 1, as the main housing component of the lamp body structure, specifically includes a frame strip 11 and a mounting space 12 formed by the frame strip 11. The frame strip 11 includes a base 111 and a support portion 112, with the support portion 112 extending from the bottom of the base 111 toward the mounting space 12. The optical component 2 is disposed on the support portion 112, and a mounting groove 13 is provided between the optical component 2 and the side of the base 111.
[0052] The heat sink 3 includes a first heat sink 31 and a second heat sink 32, and the buffer assembly 5 includes a first elastic member 51 and a second elastic member 52. The light source assembly 4 includes a substrate 41 and LED beads 42 attached to the substrate 41. The light source assembly 4 is fixed on the first heat sink 31 and installed in the mounting groove 13 together with the first elastic member 51.
[0053] During installation, the LED beads 42 face the optical component 2, while the other side of the substrate 41 is fixed to the first heat sink 31. During operation, the LED beads 42 of the light source component 4 generate a large amount of heat, which is transferred through the substrate 41 to the first heat sink 31 and then diffused outwards from the first heat sink 31. Providing a second heat sink 32 increases the heat dissipation area, thereby improving the overall heat dissipation efficiency of the lamp body structure and reducing the temperature of the lamp body structure during operation. The lower operating temperature further reduces the thermal deformation of the optical component 2.
[0054] The first elastic element 51, the light source assembly 4, and the first heat dissipation part 31 are all disposed within the mounting groove 13. When the optical component 2 is heated and deforms, its edge expands and deforms towards the light source assembly 4. If the positions of the light source assembly 4 and the first heat dissipation part 31 within the mounting groove 13 are completely fixed, the LED beads 42 of the light source assembly 4 may be pressed against the edge of the optical component 2. Under extreme conditions, such as when the ambient temperature rises, the operating temperature of the light source assembly 4 will also rise accordingly, and the unilateral deformation of the optical component 2 can reach 1 mm, which is sufficient to damage the light source assembly 4. In addition, if the light source assembly 4 is subjected to prolonged compression, it will also affect the service life of the LED beads 42.
[0055] With the first elastic element 51, the light source assembly 4 floats under pressure, moving along with the optical assembly 2 due to thermal deformation. The pressure on the light source assembly 4 is absorbed by the first elastic element 51, significantly alleviating the pressure on the light source assembly 4. The light incident distance between the light source assembly 4 and the optical assembly 2 remains relatively stable, resulting in more stable light output. Under long-term operation, the light output distortion of the entire lamp structure is reduced.
[0056] Even when the light source assembly 4 stops working, heat dissipation continues. As the temperature decreases, the deformation of the optical assembly 2 recovers. Driven by the elastic force of the first elastic element 51, the light source assembly 4 and the first heat dissipation part 31 will gradually return to their pre-operation state, thus ensuring that their initial positions are consistent during startup.
[0057] In some embodiments, the side-emitting lamp body structure 100 includes a back plate 6, which is fixedly connected to the face frame 1. The back plate 6 and the frame strip 11 form a receiving cavity 14, and the mounting space 12 is disposed in the receiving cavity 14. A second elastic member 52 is disposed in the receiving cavity 14 and abuts against the optical component 2 and the back plate 6 in the thickness direction X. When the optical component 2 is deformed by heat, due to uneven heating, heat is transferred from the periphery to the center. Because of the temperature difference, the optical component 2 as a whole will also undergo slight warping deformation. Long-term warping deformation will cause irreversible deformation of the optical component 2, affecting the luminous efficiency of the optical component 2. During the thermal deformation and deformation recovery process of the optical component 2, the second elastic member 52 ensures the shape stability of the optical component 2 while also suppressing the influence of long-term warping deformation and deformation in the thickness direction X on the optical component 2, resulting in stable long-term light output quality and effectively extending the service life.
[0058] The first elastic element 51 and the second elastic element 52 are made of elastic materials, such as EVA, sponge, rubber, etc. In other embodiments, the first elastic element 51 and the second elastic element 52 may also contain a certain amount of thermally conductive material, such as thermal grease, to achieve a certain thermal conductivity.
[0059] Furthermore, such as Figure 4As shown, the support portion 112 has a support surface 1121, the first heat dissipation portion 31 is perpendicular to the support surface 1121, and the second heat dissipation portion 32 is parallel to the support surface 1121. The heat dissipation component 3 can more closely wrap around the edges of the light source assembly 4 and the optical assembly 2, and the heat dissipation direction in two dimensions also improves the heat dissipation efficiency of the heat dissipation component 3. The first elastic component 51 is fixed to the frame strip 11, and the first heat dissipation portion 31 is adjacent to the first elastic component 51. There is a gap 15 between the two, which can effectively reduce the contact frequency between the first heat dissipation portion 31 and the first elastic component 51. Under ideal ambient temperature, the number of elastic deformations of the first elastic component 51 is reduced, thereby extending the service life of the first elastic component 51. Due to the space constraints of the first elastic component 51, the shape of the first elastic component 51 is narrow and its pressure bearing capacity is limited. The gap 15 can also reduce the possibility of elastic failure of the first elastic component 51 due to excessive deformation.
[0060] To ensure the optimal distance between the light source component 4 and the optical component 2, and to guarantee the best luminous efficiency of the optical component 2, the second heat sink 32 is attached to the optical component 2. In practical applications, there is a certain gap between the edges of the light source component 4 and the optical component 2. A gap that is too large or too small will result in poor overall light output, and a gap that is too small will cause the light source component 4 to be crushed and damaged. Therefore, ensuring a stable gap is fundamental to achieving consistently high-quality luminous efficiency. The second heat sink 32, attached to the optical component 2, precisely maintains the appropriate gap between the edges of the light source component 4 and the optical component 2. Through the second heat sink 3, the heat from the light source component 4 is rapidly transferred along the heat sink 3, keeping the temperature of the edges of the optical component 2 similar and preventing excessive local thermal deformation of the optical component 2 that could cause the light source component 4 to be crushed.
[0061] In some embodiments, continue reading Figure 4 The heat sink 3 also includes a bent portion 33, which is located between the first heat sink 31 and the second heat sink 32, and abuts against the back plate 6. With the bent portion 33, the heat sink 3 will have a larger heat dissipation area, and the heat sink 3 will fit more closely to the light source assembly 4 and the optical assembly 2, resulting in higher shape strength and a more stable structure. Abutting against the back plate 6 ensures that the heat sink 3 is stable and secure after installation.
[0062] Specifically, to ensure actual heat dissipation efficiency and robustness, the first heat dissipation part 31 and the bending part 33 form a receiving groove 34, in which the light source assembly 4 is located. One side of the substrate 41 abuts against the bending part 33, and the other side abuts against the supporting part 112. Furthermore, after the light source assembly 4 is defined by the receiving groove 34, its position is more accurate, thereby ensuring the angle of light incident on the optical assembly 2.
[0063] Furthermore, the bottom of the substrate 41 is attached and fixed to the first heat dissipation part 31 by a heat dissipation adhesive 7, which is a heat dissipation double-sided adhesive or a heat dissipation adhesive coating.
[0064] Continue reading Figures 1-4 In this embodiment, the optical component 2 includes a diffuser 21, a light guide 22, and a reflector 23. The light guide 22 is disposed between the diffuser 21 and the reflector 23. The LED bead 42 faces the side of the light guide 22, and the diffuser 21 is disposed on the support portion 112. The LED bead 42 generates light through energization of the PN junction. The light is emitted to the side of the light guide 22, and after optical processing between the light guide 22, the reflector 23, and the diffuser 21, it is emitted outward from the diffuser 21. Due to the multiple refractions and reflections, the emitted light has a softer visual effect and a larger illumination area.
[0065] During installation, the reflector 23 is partially attached to the second heat dissipation part 32, thus achieving a close connection between the optical component 2 and the second heat dissipation part 32. The other part of the reflector 23 is connected to the back plate 6 through the second elastic part. The light guide 22 and the diffuser 21 are indirectly connected to the back plate 6 via the reflector 23, thereby maintaining the shape of the optical component 2 in the thickness direction X.
[0066] In summary, the side-emitting lamp body structure provided in this embodiment improves the overall heat dissipation efficiency of the lamp body structure and reduces its operating temperature by fixing the light source assembly to the first heat dissipation part and dissipating the heat generated by the light source assembly through the heat dissipation component. Furthermore, the first elastic member, the light source assembly, and the first heat dissipation part are all disposed together in the mounting groove, allowing the first elastic member to absorb the top pressure on the light source assembly after thermal expansion, preventing the light source assembly from being damaged by the optical assembly and extending its service life.
[0067] Secondly, by adopting the provided side-emitting lamp body structure, the deformation of the light source component and optical component caused by ambient temperature and operating temperature is greatly reduced, resulting in stable light output and minimal light distortion after long-term use.
[0068] Example 2:
[0069] exist Figures 1-4 Based on the above Figures 5-7 This embodiment is an optimization and adjustment based on Embodiment 1. Unlike Embodiment 1, the side-emitting lamp body structure 100 in this embodiment also includes fasteners 8, the frame strips 11 are iron frame strips, and multiple frame strips 11 are fixedly connected together by laser melting to form the face frame 1. The back plate 6 and the frame strips 11 are respectively provided with through holes 61 and mounting holes 113. The fasteners 8 pass through the through holes 61 and are fixed in the mounting holes 113, fixing the back plate 6 and the face frame 1 together.
[0070] Compared to using aluminum profiles for splicing, the iron frame provided in this embodiment is more economical. The frame 11, formed by bending iron sheets, has better overall strength than aluminum profiles. Furthermore, laser melting effectively reduces thermal stress during connection. Compared to methods like arc welding that require welding rods for connection, it eliminates the need for subsequent grinding and reshaping, resulting in lower production costs.
[0071] The locking force of the back plate 6 can be increased by increasing the number of fasteners 8, while the opposite force on the back plate 6 is the elastic force generated by the second elastic element 52. To further reduce production costs and processing steps, the mounting holes 113 can be replaced by bending the frame strip 11 to form self-tapping grooves 16, and the fasteners 8 can be fixed using standard parts such as self-tapping screws. This eliminates the need for drilling and tapping processes during production.
[0072] Example 3:
[0073] Please Figures 1-7 Based on the above Figures 8-9 This embodiment provides a panel light 200, which includes a power supply assembly 9 and a side-emitting lamp body structure 100 of either embodiment 1 or embodiment 2. Specifically, the power supply assembly 9 includes a wire connector 91, a cable 92, and a wire clamping member 93. The wire connector 91 is electrically connected to an external power source, and the wire connector 91 is electrically connected to the light source assembly 4 through the cable 92. The wire clamping member 93 fixes the cable 92 to one side frame strip 11.
[0074] The panel light 200 with power supply component 9 is easier to install and use. Furthermore, by adopting the side-emitting lamp body structure 100 described in Embodiment 1 or Embodiment 2, the panel light 200 has a longer service life while ensuring excellent light output efficiency and stable operation. In addition, the above effects can be achieved using only the heat sink 3 and the buffer component 5. Since the heat sink 3 and the buffer component 5 are widely available and easy to implement, the overall structure of the panel light 200 is simpler and the cost is lower.
[0075] The above description is merely an example and illustration of the structure of this utility model, and while the description is quite specific and detailed, it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these obvious substitutions all fall within the protection scope of this utility model.
