Description

Technical Field

[0001] This application relates to the technical field of LED lighting fixtures, and in particular to a hot-rhine LED smart lighting fixture. Background Technology

[0002] Rhinestone LED lights are an innovative type of lighting fixture that combines traditional rhinestone craftsmanship with modern LED lighting technology. Their most distinctive feature is the rhinestones inlaid or glued to the surface of the light fixture. These rhinestones reflect brilliant light under illumination, adding a unique decorative effect to the fixture. The rhinestone process not only enhances the visual appeal of the light fixture but also makes it an integral part of the interior decoration, instantly elevating the style and atmosphere of a space. This design is particularly suitable for high-end homes, luxury hotels, and fashionable venues where a prominent decorative effect is desired.

[0003] The core of hot-rhine LED lighting fixtures lies in their LED light source. LED (light-emitting diode) light sources are renowned for their high efficiency and energy saving. Compared to traditional incandescent and fluorescent lamps, LED light sources consume less energy and have a longer lifespan. This means users can significantly reduce electricity bills and decrease the frequency of bulb replacements. Furthermore, LED light sources offer advantages such as high brightness, rich colors, and dimmability, providing stable and soft lighting effects to meet the lighting needs of various scenarios.

[0004] For example, the LED lamp with application number CN201810686851.4 relates to the field of LED lighting technology. This prior art includes a substrate, an exhaust cover, a driving component, air guide vanes, multiple LED beads, and multiple heat sinks. The substrate includes a substrate body and a connecting base. The substrate body is connected to the connecting base, which has a mounting cavity and multiple ventilation holes, all of which communicate with the mounting cavity. Multiple LED beads are disposed on the substrate body. The exhaust cover is disposed inside the mounting cavity and has exhaust holes. The driving component passes through the exhaust cover. The air guide vanes are disposed at the power output end of the driving component and are located inside the mounting cavity. Because the substrate and the heat sinks are directly connected, the heat on the substrate is quickly conducted to the heat sinks for heat dissipation. Compared with traditional LED lamps, the above-mentioned LED lamp has a better heat dissipation effect and extends the service life of the LED lamp.

[0005] However, the aforementioned existing technologies still have some shortcomings in addressing heat dissipation in lighting fixtures:

[0006] In the prior art, multiple heat sinks are welded to the side of the connector away from the substrate body and are distributed at intervals along the circumference of the connector. The presence of heat sinks increases the heat dissipation area of ​​the connector and further promotes heat dissipation. However, the heat sinks are affected by the ambient temperature. The higher the ambient temperature, the worse the heat dissipation effect. If the lamp is in a high-temperature environment, the temperature of the outside air is high, and the heat exchange efficiency will decrease.

[0007] During the connection of heat sinks and connectors, gaps are difficult to completely avoid, regardless of whether welding or bonding is used. These gaps may be caused by process limitations, material deformation, or surface unevenness, and their presence significantly increases contact thermal resistance. Contact thermal resistance refers to the thermal resistance generated when heat is transferred between two contact surfaces due to surface unevenness or gaps. This accumulation leads to localized temperature increases, further exacerbating the difficulty of heat transfer.

[0008] Based on this, and given the above viewpoints, there is still room for improvement in existing technologies for heat dissipation of lighting fixtures. Summary of the Invention

[0009] To solve the above-mentioned technical problems, this application provides a hot-rhine LED smart lamp, which adopts the following technical solution:

[0010] A hot-rhine LED smart lamp includes a housing with an opening at the lower end, a lampshade inside the housing, a lamp plate rotatably mounted at the lower end of the lampshade, a drive shaft connected to the lamp plate rotatably passing through the housing and the lampshade together, a number of LED beads arranged in a matrix on the lamp plate, and a heat sink inside the lampshade.

[0011] The heat sink includes a partition plate and a heat-conducting plate installed inside the lamp cover. Both the partition plate and the heat-conducting plate are rotatably connected to the drive shaft. A bottom cavity is formed between the lower end of the partition plate and the lamp panel. The bottom cavity is filled with a phase change material. A connecting ring is installed in the opening. Glass located below the lamp panel is installed in the connecting ring.

[0012] Preferably, the heat sink further includes a central cavity formed between the partition plate and the heat-conducting plate, a top cavity formed between the heat-conducting plate and the top of the lamp cover, a heat-conducting rod corresponding to each lamp bead passing through the partition plate, and a contact end that contacts the lamp bead after the lower end of the heat-conducting rod passes through the lamp plate.

[0013] Preferably, the contact end has a cavity, and the heat-conducting rod has a heat-conducting hole communicating with the cavity.

[0014] Preferably, a circulation element is provided inside the top cavity;

[0015] The circulation component includes a heat-conducting pipe installed in the middle cavity. The heat-conducting pipe has a tortuous section in the middle cavity. Water inlet pipe and water outlet pipe are respectively installed at both ends of the heat-conducting pipe. One end of the water outlet pipe and the water inlet pipe are connected to the top cavity.

[0016] Preferably, the inlet pipe and the outlet pipe are located at opposite ends of the top cavity.

[0017] Preferably, a turntable connected to the drive shaft is rotatably arranged inside the top cavity. The turntable has circumferentially evenly distributed sliding grooves. A sliding rod is slidably arranged in the sliding groove. A return spring is arranged between one end of the sliding rod and the sliding groove.

[0018] Preferably, an annular cavity is formed between the turntable and the inner cavity, and an arc-shaped baffle is provided between the water inlet pipe and the water outlet pipe located inside the annular cavity, and a circulation cavity is formed between two adjacent sliding rods.

[0019] Preferably, the end of the sliding rod is rotatably provided with a rotating rod, which abuts against the arc-shaped baffle and the inside of the circulation chamber.

[0020] Preferably, both the inlet pipe and the outlet pipe are located outside the lampshade and are surrounded by a surrounding section.

[0021] Preferably, the outer circumference of the lamp panel is provided with several fan blades located directly below the surrounding section, and the connecting ring is provided with ventilation holes.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The cavity of this invention is filled with a phase change material. The phase change material absorbs heat and melts at high temperature and releases heat and solidifies at low temperature, forming a temperature buffer. When the lamp is working, the heat generated by the lamp beads is continuously transferred to the phase change material, causing it to continuously absorb heat and melt. When the lamp is turned off or the load is reduced, the temperature inside the cavity begins to drop, and the liquid phase change material gradually solidifies, releasing the latent heat absorbed earlier. This process helps to maintain the temperature stability inside the lamp and avoid a sudden drop in temperature.

[0024] 2. The phase change material in the bottom cavity of this invention absorbs the heat transferred from the heat-conducting rod and undergoes a phase change (from solid to liquid), thereby absorbing a large amount of latent heat. The phase change material maintains a relatively constant temperature during the phase change process, providing a temperature buffer and avoiding drastic temperature fluctuations of the heat-conducting rod and the LED.

[0025] Meanwhile, the heat-conducting liquid in the middle cavity enters the cavity through the heat-conducting hole. The temperature of the heat-conducting rod is absorbed by the phase change material in the bottom cavity, and some of the heat is absorbed by the heat-conducting liquid. The heat-conducting hole allows the heat-conducting liquid in the middle cavity to enter the cavity of the heat-conducting rod and exchange heat directly with the heat-conducting rod.

[0026] 3. In this invention, the heat-conducting fluid flows inside the heat-conducting pipe, absorbing the heat generated inside the lamp (such as lamp beads, drive shaft, etc.), and the temperature rises. The heated heat-conducting fluid enters the circulating section through the water inlet pipe. The coolant is cooled in the circulating section, and the temperature drops. The cooled coolant flows back into the heat-conducting pipe through the water outlet pipe to continue absorbing the heat inside the lamp, forming a cycle. Attached Figure Description

[0039] The following is in conjunction with the appendix Figures 1 to 11 This application will be described in further detail.

[0040] This application discloses a hot-rhine LED smart lamp that generates airflow through rotation for heat dissipation, achieving an effective passive heat dissipation method. This design not only effectively reduces the coolant temperature but also further enhances airflow through vents, improving the overall heat dissipation effect.

[0041] Example 1:

[0042] Reference Figure 1 , Figure 2 and Figure 3 As shown, a hot-rhine LED smart lamp includes a housing 1, which is an outer protective structure with an opening 11 at the lower end. A lampshade 2 is disposed inside the housing 1. The lampshade 2 is located inside the housing 1 and is used to protect the internal components and provide a decorative effect. A lamp plate 21 is rotatably disposed at its lower end for emitting light. A drive shaft 3 connected to the lamp plate 21 is rotatably disposed on the housing 1 and the lampshade 2. A number of LED beads 31 are arranged in a matrix on the lamp plate 21.

[0043] The motor drives the drive shaft 3 to rotate, which in turn drives the lamp plate 21 to rotate the lamp beads 31. Since the lamp plate 21 is directly connected to the drive shaft 3, the rotation speed of the lamp plate 21 is the same as that of the drive shaft 3. The lamp beads 31 on the lamp plate 21 rotate together with the lamp plate 21. During the rotation, the light emitted by the lamp beads 31 will form a dynamic light and shadow effect in the space, increasing the aesthetic appeal of the lamp.

[0044] When the LED bead 31 is working, it generates heat. The rotating lamp plate 21 can promote airflow and enhance the heat dissipation effect. At the same time, the heat sink 4 is installed inside the lamp cover 2. The heat sink 4 is in close contact with the lamp plate 21 to ensure that the heat can be transferred quickly. Thermal grease or thermal pads can be used to fill the tiny gaps between the contact surfaces to further improve the heat conduction efficiency.

[0045] A connecting ring 46 is provided inside the opening 11, and a glass 47 located below the lamp panel 21 is provided inside the connecting ring 46. The glass 47 can effectively protect the lamp beads 31 and the lamp panel 21, preventing dust, moisture and other foreign objects from entering the lamp.

[0046] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, specifically, the heat sink 4 includes a partition plate 41 and a heat-conducting plate 42 disposed inside the lamp cover 2, and both the partition plate 41 and the heat-conducting plate 42 are rotatably connected to the drive shaft 3. A bottom cavity 43 is formed between the lower end of the partition plate 41 and the lamp plate 21. The bottom cavity 43 is filled with a phase change material. The phase change material absorbs heat and melts at high temperature and releases heat and solidifies at low temperature, forming a temperature buffer.

[0047] When the ambient temperature rises, the phase change material absorbs heat and transforms from a solid to a liquid state. This process absorbs a large amount of latent heat, causing the material temperature to remain relatively constant during the phase change. When the ambient temperature decreases, the liquid phase change material releases heat and solidifies back to a solid state. This process releases the previously absorbed latent heat, again keeping the material temperature relatively stable. By absorbing and releasing heat, the phase change material can maintain a relatively stable temperature within a certain temperature range. This temperature buffering effect can effectively reduce temperature fluctuations and provide a more stable thermal environment.

[0048] When the lamp is working, the heat generated by the lamp bead 31 is continuously transferred to the phase change material, causing it to continuously absorb heat and melt. When the lamp is turned off or the load is reduced, the temperature inside the cavity 43 begins to drop, and the liquid phase change material gradually solidifies, releasing the latent heat absorbed earlier. This process helps to maintain the temperature stability inside the lamp and avoid a sudden drop in temperature.

[0049] A cavity 44 is formed between the partition plate 41 and the heat-conducting plate 42. A heat-conducting liquid is injected into the cavity 44. The heat-conducting liquid should have a high thermal conductivity to ensure that heat can be transferred quickly. When the LED bead 31 is working, the heat generated is transferred through the lamp plate 21 to the phase change material and then to the partition plate 41. The heat is transferred to the heat-conducting plate 42 through the heat-conducting liquid.

[0050] A top cavity 45 is formed between the heat-conducting plate 42 and the top of the lamp cover 2. Cooling liquid is injected into the top cavity 45. The cooling liquid should have high heat capacity and good thermal conductivity to ensure that it can effectively absorb and transfer heat. The cooling liquid circulates in the top cavity 45 and carries away the heat through convection.

[0051] A heat-conducting rod 48 corresponding to each LED bead 31 is inserted through the partition plate 41. The lower end of the heat-conducting rod 48 passes through the lamp plate 21 and is provided with a contact end 481 that contacts the LED bead 31. The contact end 481 contacts the LED bead 31 and transfers heat to the heat-conducting rod 48. The phase change material in the bottom cavity 43 absorbs the heat transferred from the heat-conducting rod 48 and undergoes a phase change (from solid to liquid), thereby absorbing a large amount of latent heat. The phase change material maintains a relatively constant temperature during the phase change process, providing a temperature buffer and avoiding drastic temperature fluctuations of the heat-conducting rod 48 and the LED bead 31.

[0052] The contact end 481 has a cavity 482. The heat-conducting rod 48 has a heat-conducting hole 483 that communicates with the cavity 482. The heat-conducting liquid in the middle cavity 44 enters the cavity 482 through the heat-conducting hole 483. The temperature of the heat-conducting rod 48 is absorbed by the phase change material in the bottom cavity 43. At the same time, some of the heat is absorbed by the heat-conducting liquid. The heat-conducting hole 483 allows the heat-conducting liquid in the middle cavity 44 to enter the cavity 482 of the heat-conducting rod 48 and exchange heat directly with the heat-conducting rod 48.

[0053] Reference Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a circulation component 5 is provided in the top cavity 45, which drives the coolant to circulate in the top cavity 45, thereby achieving a high-efficiency heat dissipation effect.

[0054] Specifically, the circulation component 5 includes a heat-conducting pipe 51 disposed in the middle cavity 44. The heat-conducting pipe 51 is provided with a tortuous section 511 in the middle cavity 44. A water inlet pipe 52 and a water outlet pipe 53 are respectively disposed at both ends of the heat-conducting pipe 51. One end of the water outlet pipe 53 and the water inlet pipe 52 are connected to the top cavity 45. The water inlet pipe 52 and the water outlet pipe 53 are located at opposite ends of the top cavity 45.

[0055] When the motor drives the drive shaft 3 to rotate, the drive shaft 3 will drive the turntable 54 connected to it to rotate inside the top cavity 45, so that the turntable 54 and the drive shaft 3 rotate synchronously. The turntable 54 has a circumferentially evenly distributed sliding groove 541. A sliding rod 55 is slidably arranged in the sliding groove 541. A return spring 56 is arranged between one end of the sliding rod 55 and the sliding groove 541. The return spring 56 will press against the sliding rod 55, so that the sliding rod 55 has the potential energy to always move out of the sliding groove 541.

[0056] An annular cavity 57 is formed between the turntable 54 and the inner cavity, and a circulation cavity 59 is formed between two adjacent sliding rods 55. An arc-shaped baffle 58 is provided between the water inlet pipe 52 and the water outlet pipe 53, located in the annular cavity 57. When the turntable 54 drives the sliding rod 55 to rotate, one end of the sliding rod 55 will abut against the edge of the arc-shaped baffle 58, causing the sliding rod 55 to move into the sliding groove 541 and compress the return spring 56. At this time, the volume of the corresponding circulation cavity 59 will decrease, and the cooling liquid in the circulation cavity 59 will be squeezed into the water inlet pipe 52 and then pass through the heat conduction rod 48 into the water inlet pipe 52.

[0057] When the sliding rod 55 passes the lowest point of the arc-shaped baffle 58, the return spring 56 pushes the sliding rod 55 to press against the arc-shaped baffle 58. At this time, the sliding rod 55 extends outward, and the volume of the small circulation chamber 59 on the corresponding side increases, allowing the coolant entering the inlet pipe 52 to enter the circulation chamber 59. Then, the volume of the circulation chamber 59 decreases and enters the outlet pipe 53 to form a circulation.

[0058] As the turntable 54 continues to rotate, the sliding rod 55 moves back and forth in the sliding groove 541, causing the volume of the circulation chamber 59 to change continuously. When the volume of the circulation chamber 59 decreases, the coolant is squeezed into the inlet pipe 52, and when the volume increases, it enters the circulation chamber 59. Then, as the volume of the circulation chamber 59 decreases, it enters the outlet pipe 53, forming a continuous circulation flow.

[0059] The tortuous section 511 increases the flow path and contact area of ​​the heat transfer fluid within the channel, thereby improving heat transfer efficiency. The tortuous section 511 extends the flow path of the heat transfer fluid, allowing it more time to exchange heat with the heat source. The heat transfer fluid flows through the tortuous section 511 as it flows within the central cavity 44 or the cooling channel. Due to the shape of the tortuous section 511, the flow path of the heat transfer fluid becomes more complex, and turbulence is formed within the tortuous section 511. The tortuous section 511 extends the flow path of the heat transfer fluid, allowing it more time to exchange heat with the heat source.

[0060] The end of the sliding rod 55 is rotatably provided with a rotating rod 551. The rotating rod 551 abuts against the arc-shaped baffle 58 and the inside of the circulation cavity 59. As the turntable 54 rotates, the sliding rod 55 moves in the sliding groove 541, and the rotating rod 551 also rotates accordingly, reducing the friction of the sliding rod 55.

[0061] Example 2:

[0062] Reference Figure 10 and Figure 11 As shown, based on Embodiment 1, both the inlet pipe 52 and the outlet pipe 53 are located outside the lampshade 2 and are provided with a surrounding section 6 that surrounds the lampshade 2. Several fan blades 61 are provided on the outer circumference of the lamp plate 21, located directly below the surrounding section 6. A vent hole 62 is provided on the connecting ring 46. The opening of the vent hole 62 allows air to enter and flow out of the lampshade 2 more freely, enhancing the airflow effect.

[0063] The rotation of the lamp panel 21 will drive the fan blades 61 to rotate, thereby generating airflow to dissipate heat from the surrounding section 6 and cool the coolant. The surrounding section 6 wraps around the outside of the lamp cover 2, forming an annular channel to accommodate the water inlet pipe 52 and the water outlet pipe 53, and dissipates heat through airflow to cool the coolant, which then flows back into the heat pipe 51 to cool the heat transfer fluid.

[0064] That is, the heat-conducting fluid flows inside the heat-conducting pipe 51, absorbing the heat generated inside the lamp (such as the lamp bead 31, drive shaft 3, etc.), and the temperature rises. The heated heat-conducting fluid enters the circulating section 6 through the water inlet pipe 52. The coolant is cooled in the circulating section 6, and the temperature drops. The cooled coolant flows back into the heat-conducting pipe 51 through the water outlet pipe 53 to continue absorbing the heat inside the lamp, forming a cycle.

[0065] The implementation principle of this invention is as follows:

[0066] (1): The drive shaft 3 is driven by the motor to rotate, and the drive shaft 3 drives the lamp plate 21 to rotate together with the lamp beads 31. Since the lamp plate 21 is directly connected to the drive shaft 3, the rotation speed of the lamp plate 21 is the same as that of the drive shaft 3. The lamp beads 31 on the lamp plate 21 rotate together with the lamp plate 21. During the rotation, the light emitted by the lamp beads 31 will form a dynamic light and shadow effect in the space, increasing the aesthetic appeal of the lamp.

[0067] (2): When the lamp is working, the heat generated by the lamp bead 31 is continuously transferred to the phase change material, causing it to continuously absorb heat and melt. When the lamp is turned off or the load is reduced, the temperature inside the cavity 43 begins to drop, and the liquid phase change material gradually solidifies, releasing the latent heat absorbed earlier. This process helps to maintain the temperature stability inside the lamp and avoid a sudden drop in temperature.

[0068] (3): The heat transfer fluid should have a high thermal conductivity to ensure that heat can be transferred quickly. When the LED bead 31 is working, the heat generated is transferred through the lamp board 21 to the phase change material and then to the separator plate 41. The heat is transferred through the heat transfer fluid to the heat transfer plate 42.

[0069] (4): When the motor drives the drive shaft 3 to rotate, the drive shaft 3 will drive the turntable 54. As the turntable 54 continues to rotate, the sliding rod 55 moves back and forth in the sliding groove 541, causing the volume of the circulation chamber 59 to change continuously. When the volume of the circulation chamber 59 decreases, the coolant is squeezed into the inlet pipe 52. When the volume increases, it enters the circulation chamber 59. Then, as the volume of the circulation chamber 59 decreases, it enters the outlet pipe 53, forming a continuous circulation flow.

[0070] (5): The rotation of the lamp plate 21 will drive the fan blade 61 to rotate, thereby generating airflow to dissipate heat on the surrounding section 6 and achieve cooling of the coolant. The surrounding section 6 wraps around the outside of the lamp cover 2 to form an annular channel for accommodating the inlet pipe 52 and the outlet pipe 53, and dissipates heat through airflow. The heat-conducting liquid flows in the heat-conducting pipe 51, absorbing the heat generated inside the lamp (such as the lamp bead 31, drive shaft 3, etc.), and the temperature rises. The heat-conducting liquid with the increased temperature enters the surrounding section 6 through the inlet pipe 52. The coolant is cooled in the surrounding section 6, and the temperature decreases. The cooled coolant flows back into the heat-conducting pipe 51 through the outlet pipe 53 to continue absorbing the heat inside the lamp and forming a cycle.

[0071] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
