Detailed Implementation

[0030] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0031] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back) are merely for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] To address the problem of insufficient heat dissipation in existing lighting fixtures, the inventors of this application provide a lighting fixture as described below and shown in the accompanying drawings. During the actual research and development process, the inventors discovered that in addition to the light source component accumulating a large amount of heat, the pressure block, influenced by the light source component, also accumulates a significant amount of heat. This combined accumulation of heat can easily affect the performance of the lighting fixture.

[0034] In response, the inventors of this application have designed a lamp, the structure of which will be described below with reference to the accompanying drawings.

[0035] See Figures 1 to 3 One embodiment of this application provides a lamp 100, which includes a light source 10, a pressure block 20, and a heat spreader 30.

[0036] The light source 10 includes a lamp plate 11 and a light-emitting part 12 disposed on the lamp plate 11, the light-emitting part 12 being capable of emitting light. A pressure block 20 is disposed on the side of the lamp plate 11 where the light-emitting part 12 is located. The pressure block 20 has a hollow light-transmitting cavity 201, which is positioned corresponding to the light-emitting part 12, allowing light emitted from the light-emitting part 12 to be emitted through the light-transmitting cavity 201. A heat-dissipating plate 30 has a first heat-dissipating zone 301 and a second heat-dissipating zone 302. The first heat-dissipating zone 301 is disposed on the surface of the lamp plate 11 opposite to the light-emitting part 12 to conduct heat to the light source 10. The second heat-dissipating zone 302 is disposed on the surface of the pressure block 20 to conduct heat to the pressure block 20.

[0037] For the lamp 100 of this application, the first heat-equalizing zone 301 of the heat-equalizing plate 30 corresponds to the surface of the lamp plate 11 facing away from the light-emitting part 12. The heat-equalizing plate 30 can conduct heat generated by the light-emitting part 12 on the lamp plate 11, avoiding local overheating of the lamp plate 11, thereby effectively reducing the operating temperature of the light source 10, slowing down light decay, extending the service life of the light-emitting part 12, and maintaining the stability of its luminous efficiency. Furthermore, the second heat-equalizing zone 302 of the heat-equalizing plate 30 is disposed on the surface of the pressure block 20, allowing the heat-equalizing plate 30 to conduct heat accumulated on the pressure block 20, preventing the heat generated by the light source 10 from accumulating on the pressure block 20, further improving the heat dissipation efficiency of the lamp 100. The technical solution of this application, through the dual-zone heat conduction arrangement of the heat-equalizing plate 30, enables the light source 10 and the pressure block 20 to dissipate heat collaboratively, thereby efficiently optimizing the heat dissipation performance of the lamp 100, which is beneficial for achieving a high-power and high-reliability design of the lamp 100.

[0038] In some embodiments of this application, the light source 10 can be a COB light source, which may include a lamp board 11 and a light-emitting part 12 disposed on the lamp board 11. The light-emitting part 12 is capable of emitting light when energized.

[0039] The light-emitting part 12 may include a substrate and a plurality of LED chips packaged on the substrate. The substrate supports the LED chips and provides electrical connection and primary heat dissipation. The substrate is disposed on the lamp board 11, and the LED chips are disposed on the surface of the substrate facing away from the lamp board 11. The lamp board 11 provides mechanical fixation and electrical connection for the light-emitting part 12.

[0040] The light-emitting part 12 may include two or more light-mixing chips that can be mixed to form white light. The two or more light-mixing chips are selected from: warm white LED chips, neutral white LED chips, cool white LED chips, red LED chips, blue LED chips, green LED chips, yellow LED chips, amber LED chips, and cyan LED chips.

[0041] In some examples, the substrate and the lamp panel 11 can be set as an integral structure to reduce the overall thickness of the lamp 100 and achieve a miniaturized design of the lamp 100.

[0042] In addition, in other examples, the light source 10 can also be an LED patch structure directly soldered onto the lamp board 11, a Mini LED / Micro LED array structure, an OLED (organic light-emitting diode) light source, a laser light source, a planar fluorescent light source, a gas discharge light source, a filament lamp light source, etc.

[0043] Furthermore, combined Figure 4 and Figure 5 As shown, in some embodiments of this application, the light source 10 may further include a terminal block 13, which is disposed on the surface of the lamp board 11 where the light-emitting part 12 is provided, and the terminal block 13 is electrically connected to the light-emitting part 12.

[0044] Terminal 13 serves as a conductive interface between the light-emitting part 12 and an external power supply or drive circuit, thereby stably transmitting the input electrical energy to the light-emitting part 12 and ensuring the normal light emission of the light-emitting chip. Multiple sets of terminal 13 can be provided. The light-emitting part 12 is a light-emitting chip, and multiple sets of terminal 13 can be connected to the positive and negative terminals of the light-emitting chip.

[0045] In some examples, the terminal block 13 is located near the edge of the lamp board 11. The connection between the lamp board 11 and the external drive power / control line can be achieved through the terminal block 13 on the edge of the lamp board 11, which can be plugged and unplugged without the need for complex wiring inside the lamp 100; and, when maintaining the lamp 100, only the terminal block 13 on the edge needs to be removed, and the core structure such as the pressure block 20 and the heat spreader 30 does not need to be changed, which greatly improves the efficiency of assembly and maintenance.

[0046] In this example, the light source 10 may also include a cover plate 14. The cover plate 14 has a through opening 141 inside, and the edge of the cover plate 14 has a notch 142. The cover plate 14 is disposed on the surface of the lamp plate 11 where the light-emitting part 12 is provided, the light-emitting part 12 is accommodated in the through opening 141, and the wiring terminal 13 is disposed corresponding to the notch 142.

[0047] The cover plate 14 covers the surface of the lamp board 11 where the light-emitting part 12 is located, which can isolate the circuit components other than the light-emitting part 12 from the external environment, prevent dust and moisture from directly corroding the electrical components, and improve the overall reliability of the light source 10. In addition, the cover plate 14 can prevent the pressure block 20 from directly pressing the circuit components on the lamp board 11, and prevent the light-emitting part 12 from failing due to local deformation of the lamp board 11 under stress.

[0048] In this example, the cover plate 14 can be detachably mounted on the lamp panel 11 using screws. In other examples, the cover plate 14 can also be connected to the lamp panel 11 by means of snap-fit, interference fit, or other methods.

[0049] Combination Figure 5 and Figure 6 As shown, in some examples, the luminaire 100 may also include an insulating plate 15 made of insulating material. The insulating plate 15 is disposed on the surface of the pressure block 20 facing the light-emitting part 12, and the insulating plate 15 is disposed corresponding to the wiring terminal 13.

[0050] The insulating plate 15, serving as an intermediate layer between the pressure block 20 and the terminal block 13, can block the direct electrical connection between the pressure block 20 and the terminal block, preventing the risk of short circuits or leakage caused by accidental contact of metal parts. Furthermore, the insulating plate 15 can prevent external conductive materials from contacting or directly contacting the terminal block 13 through the pressure block 20, ensuring the stable operation of the internal circuitry of the lamp 100.

[0051] Further, see Figures 2 to 3 The lamp 100 of this application also includes a pressure block 20, which is disposed on the side of the lamp plate 11 where the light-emitting part 12 is provided. The pressure block 20 is provided with a hollow light-transmitting cavity 201, which is disposed corresponding to the light-emitting part 12, and the light emitted by the light-emitting part 12 can be emitted through the light-transmitting cavity 201.

[0052] In this application, the pressure block 20 provides physical protection for the light-emitting part 12 on the lamp panel 11, preventing it from being damaged by external impacts, scratches, etc., thereby improving the reliability and stability of the lamp 100. Furthermore, the light-transmitting cavity 201 of the pressure block 20 is positioned corresponding to the light-emitting part 12, guiding the light emitted by the light-emitting part 12 to emit in a specific direction, reducing light scattering, improving light utilization and light emission effect, and making the illumination of the lamp 100 more concentrated and uniform. In addition, the pressure block 20 has a certain heat conduction function, helping to dissipate the heat generated by the light-emitting part 12, reducing the temperature of the light-emitting part 12, extending its service life, and improving the overall performance of the lamp 100.

[0053] In some embodiments of this application, the pressure block 20 includes a block body 21 and an extension 22 connected to the block body 21. The block body 21 has a fixing opening 211, and the extension 22 is open at both ends and hollow internally. The ends of the extension 22 are connected to the fixing opening 211 of the block body 21. The internal space of the extension 22 communicates with the fixing opening 211 to form a light-transmitting cavity 201.

[0054] In some examples, the surface of the block body 21 faces away from the extension 22, that is, the surface of the block body 21 facing the light-emitting part 12 has a recessed area 212. This recessed area 212 is used to accommodate the wiring terminal 13 on the lamp board 11, and the insulating plate 15 is fixed inside the recessed area 212. The insulating plate 15 forms a barrier between the pressure block 20 and the wiring terminal 13 to constitute insulation.

[0055] In some embodiments of this application, the inner wall of the end of the extension 22 away from the block body 21 is formed with a stepped protrusion 221. The lamp 100 also includes a lens 40, which is disposed at the protrusion 221, and the light emitted by the light-emitting part 12 can pass through the light-transmitting cavity 201 and the lens 40 and be emitted.

[0056] The lens 40 can diffuse and adjust the light distribution, reduce uneven light spots, and improve the uniformity of light output from the luminaire 100. The stepped protrusion 221 can provide a precise mechanical positioning reference for the lens 40, which on the one hand ensures the stable assembly of the lens 40 on the pressure block 20, and on the other hand minimizes the error in the optical axis coincidence between the lens 40 and the light-emitting part 12, thus ensuring efficient and uniform light output from the luminaire 100.

[0057] In some examples, the surface of the flange 221 is provided with an annular groove 2211, and a sealing ring 50 is provided inside the annular groove 2211. The sealing ring 50 can be made of a flexible material, such as silicone or rubber.

[0058] The sealing ring 50 is made of flexible material and can fit tightly against the lens 40 and the raised edge 221 to form a good sealing structure. This design can effectively prevent dust, moisture and other impurities from entering the light transmission cavity 201 and the interior of the lamp 100, avoiding contamination or damage to the light-emitting part 12 and other optical components, improving the dustproof and waterproof performance of the lamp 100, and extending the service life of the lamp 100. It is especially suitable for lamps 100 in harsh conditions such as outdoor or humid environments.

[0059] Furthermore, the flexible sealing ring 50 can absorb the vibration and impact that may be generated during the use of the lamp 100 to a certain extent, reduce the impact of these external forces on the lens 40 and the internal structure of the lamp 100, prevent the lens 40 from loosening or being damaged due to vibration, improve the structural reliability and shock resistance of the lamp 100, and is suitable for some places where vibration may occur.

[0060] In some embodiments of this application, the lamp 100 may further include an assembly ring 60. The assembly ring 60 includes an annular assembly body 61, an abutment portion 62 disposed at one end of the assembly body 61 and arranged on the outer wall of the assembly body 61, and a crimping portion 63 disposed at the other end of the assembly body 61 and arranged on the inner wall of the assembly body 61.

[0061] The assembly ring 60 is sleeved and fixed to the outside of the extension 22, and the inner wall of the assembly body 61 is in contact with the outer wall of the extension 22. The abutting part 62 abuts against the surface of the block body 21, and the abutting part 62 and the block body 21 can be fixedly connected by screws. The pressing part 63 is pressed against the end face of the extension 22 away from the block body 21, and the surface of the pressing part 63 abuts against the periphery of the lens 40, so that the lens 40 is securely mounted on the pressure block 20.

[0062] Combination Figure 2 and Figure 4 As shown, the lamp 100 of this application also includes a heat spreader 30. The heat spreader 30 has a first heat spreader 301 and a second heat spreader 302. The first heat spreader 301 is disposed on the surface of the lamp plate 11 away from the light-emitting part 12 to conduct heat to the light source 10. The second heat spreader 302 is disposed on the surface of the pressure block 20 to conduct heat to the pressure block 20.

[0063] The heat spreader 30 has good thermal conductivity. The first heat spreader zone 301 corresponds to the surface of the lamp plate 11 away from the light-emitting part 12, and can quickly conduct away the heat generated by the light-emitting part 12 on the lamp plate 11, preventing the lamp plate 11 from overheating due to heat accumulation. The second heat spreader zone 302 corresponds to the surface of the pressure block 20, and can also quickly conduct away the heat absorbed by the pressure block 20, preventing the pressure block 20 from overheating, thereby effectively reducing the temperature of each component of the lamp 100 and ensuring the normal operation of the lamp 100.

[0064] In some examples, the vapor chamber 30 is a solid plate structure, which can be made of metal materials such as copper and aluminum. Among them, the vapor chamber 30 made of copper has an extremely high thermal conductivity, which can quickly and effectively conduct heat; in addition, copper has good ductility and is easy to process and shape, so it can be made into vapor chambers 30 of various shapes and sizes to meet the structural requirements of different lamps 100.

[0065] In some examples, the vapor chamber 30 can also be a plate-like structure with liquid cooling circulation. Specifically, the vapor chamber 30 may have a flow channel and / or a liquid cooling cavity inside, and a liquid cooling material may be disposed inside the liquid cooling cavity and the flow channel. The liquid cooling material may include water, methanol, acetone, etc.

[0066] In some examples, the surface of the vapor chamber 30 may be coated with a thermally conductive material. This coating material may be graphene, ceramic, etc.

[0067] Graphene possesses extremely high thermal conductivity and strength. Coating the surface of the heat spreader 30 with a graphene coating can further improve its thermal conductivity and reduce heat accumulation on the substrate surface. Simultaneously, the graphene coating also exhibits good wear resistance and corrosion resistance, protecting the heat spreader 30 substrate from external environmental erosion and extending its service life.

[0068] Ceramic coatings possess properties such as high temperature resistance, insulation, and oxidation resistance. Applying a ceramic coating to the heat spreader 30 can improve its high temperature resistance and prevent deformation or oxidation of the heat spreader 30 under high temperature environments. At the same time, the insulation properties of the ceramic coating can prevent electrical faults such as short circuits between the heat spreader 30 and other components of the lamp 100.

[0069] In addition, in some examples, fins can be provided inside the heat spreader 30. The fins can be fixed inside the heat spreader 30 at certain intervals and in a certain arrangement. The fins can be straight, wavy, or other shapes, and their material can be the same as or similar to the substrate material of the heat spreader 30 to ensure good thermal conductivity.

[0070] The fins increase the heat dissipation area inside the vapor chamber 30, enabling more efficient heat transfer from the heat source to all parts of the vapor chamber 30, thereby improving heat dissipation efficiency. Furthermore, the fins are distributed inside the vapor chamber 30, allowing heat to be conducted and diffused between different areas, reducing the temperature gradient within the vapor chamber 30 and making the surface temperature of the vapor chamber 30 more uniform, thus preventing localized overheating of the lamp 100.

[0071] In some embodiments of this application, a first temperature equalization zone 301 and a second temperature equalization zone 302 may be formed on the surface of the temperature equalization plate 30. The second temperature equalization zone 302 is annular and is arranged around the periphery of the first temperature equalization zone 301.

[0072] The heat spreader 30 includes a main body 31 and a protruding boss 32 on the main body 31. The surface of the boss 32 forms a first heat spreader zone 301, and the area of ​​the main body 31 surrounding the boss 32 forms a second heat spreader zone 302. The lamp plate 11 is fixed to the surface of the boss 32, and the second heat spreader zone 302 of the main body 31 is disposed corresponding to the surface of the pressure block 20. The lamp plate 11 can be fixed to the boss 32 with screws.

[0073] In this example, the lamp board 11 is fixed on the surface of the boss portion 32, and the surface of the boss portion 32 forms a first temperature equalization zone 301, which can directly and accurately dissipate heat from heat-generating components such as the light-emitting part 12 on the lamp board 11, so that heat can be quickly transferred to the temperature equalization plate 30, forming a concentrated protection for key heat-generating areas, and preventing the lamp board 11 from affecting the performance and lifespan of the light source component 10 due to overheating.

[0074] Furthermore, the structural design of the boss portion 32 and the main body 31 in the heat spreader 30 is compatible with the layout of the lamp plate 11 and the pressure block 20 in the lamp 100. The second heat spreader zone 302 of the main body 31 is set on the surface of the pressure block 20. While conducting heat to the pressure block 20, it can also make full use of the internal space of the lamp 100, making the entire lamp 100 structure more compact.

[0075] Furthermore, the second heat equalization zone 302 on the main body 31 is annular and surrounds the protrusion 32. When the first heat equalization zone 301 absorbs heat from the lamp panel 11, the heat can be naturally conducted to the second heat equalization zone 302 on the periphery. This annular structure provides a uniform and continuous heat conduction path, reducing obstacles and the possibility of hot spots in the heat transfer process, allowing heat to diffuse more efficiently on the heat equalization plate 30.

[0076] See Figure 4 In some examples, the luminaire 100 may also include a heat-conducting layer 70. The heat-conducting layer 70 is annular and has an opening 701. The heat-conducting layer 70 is disposed on the surface of the main body 31 and is arranged corresponding to the second temperature equalization zone 302. The surface of the pressure block 20 abuts against the second temperature equalization zone 302 through the heat-conducting layer 70. The opening 701 is provided corresponding to the boss portion 32, and the light source element 10 is housed in the opening 701.

[0077] The thermally conductive layer 70 can be made of thermally conductive adhesive. The thermally conductive layer 70 can be fixed to the heat spreader 30 by screws. The heat spreader 30 has screw holes on its surface corresponding to the second heat spreader 302 for connecting to the screws. The thermally conductive layer 70 has through holes for the screws connected to the light source 10 to pass through.

[0078] The thermally conductive layer 70, made of thermally conductive adhesive, has excellent thermal conductivity, effectively transferring heat from the surface of the pressure block 20 to the second heat equalization zone 302 of the heat equalization plate 30. The annular shape of the thermally conductive layer 70, corresponding to the second heat equalization zone 302, increases the thermally conductive contact area between the pressure block 20 and the heat equalization plate 30, reduces thermal resistance, and allows for smoother heat conduction. This improves the overall heat dissipation efficiency of the lamp 100, helps reduce the temperature around the pressure block 20 and the lamp plate 11, and ensures the normal operation of the lamp 100.

[0079] In this example, the lamp 100 may also include a pad 81. The pad 81 is a flexible element, disposed on the surface of the heat-conducting layer 70, and arranged between the heat-conducting layer 70 and the pressure block 20.

[0080] The flexible pad 81 can effectively buffer the vibration and impact that the lamp 100 may be subjected to during use, reduce the friction and collision between the pressure block 20 and the heat-conducting layer 70 and the heat spreader 30 caused by vibration, thereby protecting the various components inside the lamp 100, avoiding damage to components or loosening of connections due to long-term vibration, and improving the stability and reliability of the lamp 100.

[0081] In this example, the luminaire 100 also includes a fixing block 82, which is disposed on the surface of the heat-conducting layer 70 and arranged between the heat-conducting layer 70 and the pressure block 20. The pressure block 20 is provided with a connection port for a cable that is electrically connected to the light source 10 to pass through.

[0082] The fixing block 82 can fix the cable electrically connected to the light source 10, preventing the cable from shaking or shifting inside the lamp 100. This arrangement helps to avoid problems such as poor contact and short circuits caused by cable shaking, improving the stability and reliability of the electrical connection of the lamp 100. At the same time, the fixing block 82 can protect the cable from damage caused by external forces such as squeezing and friction, extending the service life of the cable.

[0083] In some examples, the heat-conducting layer 70 can be omitted from the lamp 100. That is, the pressure block 20 can be directly fixed to the surface of the main body 31, so that the pressure block 20 directly corresponds to the second heat equalization zone 302. The pressure block 20 is in direct contact with the second heat equalization zone 302, which shortens the heat transfer path, reduces heat loss during the transfer process, and improves heat dissipation efficiency to a certain extent.

[0084] Furthermore, such as Figure 7 As shown, in some embodiments of this application, there are two heat exchange plates 30, namely a first heat exchange plate 3001 and a second heat exchange plate 3002. The second heat exchange plate 3002 is annular and is disposed around the outer periphery of the first heat exchange plate 3001.

[0085] The surface of the first heat-equalizing plate 3001 forms a first heat-equalizing region 301, and the surface of the first heat-equalizing plate 3001 with the first heat-equalizing region 301 is connected to the surface of the lamp plate 11 opposite to the light-emitting part 12. The surface of the second heat-equalizing plate 3002 forms a second heat-equalizing region 302, and the surface of the second heat-equalizing plate 3002 with the second heat-equalizing region 302 is connected to the surface of the pressure block 20. The first heat-equalizing plate 3001 and the second heat-equalizing plate 3002 can abut against each other, or a gap can be provided.

[0086] The first heat spreader 3001 is directly connected to the surface of the lamp plate 11 away from the light-emitting part 12, and can quickly absorb the heat generated by the lamp plate 11 and concentrate it in the first heat spreader zone 301. The second heat spreader 3002 is arranged in a ring around the outer periphery of the first heat spreader 3001 and is connected to the surface of the pressure block 20. It can effectively absorb the heat transmitted from the pressure block 20, and at the same time play an auxiliary role in heat dissipation of the first heat spreader 3001. This forms a layered and interconnected heat dissipation layout, which allows heat to be dissipated more efficiently, avoids heat accumulation inside the lamp 100, and helps to improve the overall heat dissipation performance of the lamp 100.

[0087] Furthermore, the second heat spreader 3002 surrounds the first heat spreader 3001 in a ring shape, which not only plays a synergistic role in heat dissipation but also provides structural support and protection for the first heat spreader 3001. This arrangement increases the overall strength and stability of the lamp 100, making it less likely for the internal heat spreader 30 and other components to shift or be damaged when the lamp 100 is subjected to external impact or vibration, thus improving the durability of the lamp 100.

[0088] Furthermore, in some embodiments of this application, the pressure block 20 and the heat spreader 30 can be integrally formed. This arrangement eliminates the interfacial thermal resistance between the pressure block 20 and the heat spreader 30. When heat is transferred from the pressure block 20 to the heat spreader 30, it does not need to pass through the connection interface between different components, allowing for smoother conduction and thus improving heat dissipation efficiency. This more effectively dissipates the heat generated by the lamp 100, helps maintain the normal operating temperature of the lamp 100, and extends its service life.

[0089] The pressure block 20 and the heat spreader 30 are integrally formed into a whole structure. Compared with the assembled structure, it has higher structural strength and stability, and can better withstand the external impact and vibration that the lamp 100 may be subjected to during use, reducing the risk of component damage or displacement and improving the reliability of the lamp 100.

[0090] Furthermore, such as Figure 1 As shown in the present application, the lamp 100 may further include a heat dissipation base 90. The heat dissipation base 90 includes a base body 91 and a heat dissipation component 92 disposed on the base body 91.

[0091] The main body 91 is provided with a heat dissipation surface 911, and a heat spreader 30 is connected to the heat dissipation surface 911. The heat spreader 30 can guide the heat from the light source 10 and the pressure block 20 to the heat dissipation surface 911, and the heat dissipation component 92 can dissipate the heat. The heat dissipation component 92 can be a cooling fan, a pipe through which liquid cooling material flows, etc.

[0092] In some examples, the base body 91 can be a cubic structure. One side of the base body 91 can be set as a heat dissipation surface 911, and the other side of the base body 91 can be used to set a heat sink 92.

[0093] The base body 91 of the heat dissipation base 90 provides a large heat dissipation surface 911. The heat spreader 30 transfers the heat from the light source 10 and the pressure block 20 to the heat dissipation surface 911, increasing the heat dissipation area and facilitating rapid heat dissipation. Simultaneously, the heat dissipation component 92, such as a cooling fan, can accelerate airflow through forced convection, carrying away heat; the internal piping of liquid-cooled material can efficiently remove heat through liquid cooling circulation, further improving heat dissipation efficiency, effectively reducing the internal temperature of the lamp 100, and extending the service life of all components of the lamp 100.

[0094] The heat dissipation base 90 effectively dissipates heat, allowing the luminaire 100 to operate in a stable temperature environment. This avoids problems such as accelerated light decay of the light source 10, performance degradation or damage to the pressure block 20 and other components due to excessive temperature, thereby ensuring the stable performance of the luminaire 100, reducing the probability of malfunctions, and improving the reliability and stability of the luminaire 100.

[0095] By dissipating heat in a timely manner through the heat dissipation base 90, the lamp 100 can operate in a stable temperature environment, avoiding problems such as accelerated light decay of the light source 10, performance degradation or damage of the pressure block 20 and other components due to excessive temperature. This ensures the stable performance of the lamp 100, reduces the probability of failure, and improves the reliability and stability of the lamp 100.

[0096] For the luminaire of this application, the first temperature-equalizing zone of the heat spreader corresponds to the surface of the lamp panel away from the light-emitting part. The heat spreader can conduct heat generated by the light-emitting part on the lamp panel, avoiding local overheating of the lamp panel, thereby effectively reducing the operating temperature of the light source, slowing down light decay, extending the service life of the light-emitting part, and maintaining the stability of its luminous efficiency. Furthermore, the second temperature-equalizing zone of the heat spreader is located on the surface of the pressure block, allowing the heat spreader to conduct heat accumulated on the pressure block, preventing heat generated by the light source from accumulating on the pressure block, further improving the heat dissipation efficiency of the luminaire. The technical solution of this application, through the dual-zone heat conduction configuration of the heat spreader, enables the light source and the pressure block to dissipate heat collaboratively, thereby efficiently optimizing the heat dissipation performance of the luminaire and facilitating the design of high-power and high-reliability luminaires.
