Description

Technical Field

[0001] This invention belongs to the field of adjustable lighting technology and relates to an automatic sensor-activated dimming lamp. Background Technology

[0002] With the continuous development of technology, people's demands for quality of life are also increasing. In home decoration, lighting fixtures serve not only to provide illumination but also to create a warm and comfortable home atmosphere. The emergence of automatic dimming technology has made people's lives more convenient and comfortable. Automatic dimming technology refers to the use of an intelligent control system to automatically adjust the brightness and color temperature of lights according to changes in ambient light, achieving energy-saving, comfortable, and environmentally friendly effects. Its principle mainly consists of three parts: a light sensor, a controller, and the light fixture. The light sensor is the core component of automatic dimming technology; it can sense the intensity of light in the surrounding environment and transmit this information to the controller. The controller then automatically adjusts the brightness and color temperature of the lights based on the information from the light sensor.

[0003] Typical controllers are directly mounted and fixed to the light fixture, and are either non-removable or very difficult to disassemble. The controller itself has a simple structure without any protective or heat dissipation features, leading to overheating during prolonged use. Its poor heat dissipation significantly impacts its lifespan, resulting in more frequent replacements and repairs. The inconvenience of disassembling the controller further complicates repair and replacement. Current technology uses a small fan mounted on the light fixture for air cooling, but since one side of the controller is directly fixed, this air cooling only reaches the other sides, leading to uneven heat dissipation and overheating at the connection points, causing overload. Furthermore, a single air cooling method is not ideal. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an automatic sensor-activated dimming lamp to solve the problems mentioned in the background section.

[0005] The objective of this invention can be achieved through the following technical solution: An automatic sensor-activated dimming lamp includes a dimming lamp body, with a triangular support frame fixed to the lower end of the dimming lamp body. The dimming lamp body has a heat sink fixed to one side, a through hole on one side, and a wind-cooling component for blowing air into the heat sink is embedded in the through hole. One end of the wind-cooling component extends outside the heat sink, and a connecting component is provided between the wind-cooling component and the side wall of the heat sink. A mounting plate that can pass through the through hole and be embedded into the heat sink is fixed to one end of the wind-cooling component. A controller is detachably mounted on the mounting plate, and a water-cooling component for conducting heat from the controller is provided on the mounting plate. The wind-cooling component can move the mounting plate outside the heat sink. Ventilation holes are opened on both sides of the heat sink, and a dustproof mesh is fixed to the inner wall of each ventilation hole.

[0006] Furthermore, the air-cooled assembly includes a ventilation duct and a motor. The ventilation duct is fitted into a through hole, and the outer wall of the ventilation duct has symmetrically arranged limiting blocks. The heat sink has limiting holes for the guide blocks to be fitted into and connected to the through hole. The mounting plate is fixed to one end of the ventilation duct. The motor is welded to the inner wall of the ventilation duct via a connecting rod. The output shaft of the motor is fixed with fan blades, and a dustproof mesh II located at the front end of the fan blades is fixed to the inner wall of the ventilation duct.

[0007] Furthermore, the inner wall of the heat dissipation box has a slot for one end of the mounting plate to be inserted. The water cooling assembly includes a first heat-conducting block. The top of the mounting plate has a groove for the bottom of the controller to be inserted. The mounting plate has a cavity. The first heat-conducting block is fixed in the cavity. The groove is connected to the cavity. The top of the first heat-conducting block is in contact with the bottom of the controller. The top of the first heat-conducting block has several symmetrically arranged U-shaped heat dissipation blocks that pass through the mounting plate. The several heat dissipation blocks are symmetrically arranged relative to the controller. The first heat-conducting block has a heat-conducting cavity. The heat dissipation block has a U-shaped heat dissipation cavity. The heat dissipation cavity is connected to the heat-conducting cavity. The heat dissipation cavity and the heat-conducting cavity are filled with cold water.

[0008] Furthermore, the connecting assembly includes two hinge rods and two hinge seats. The bottom of the hinge seat has a slider. One end of the outer wall of the heat sink has a groove for the slider to be engaged. The outer wall of the ventilation duct has symmetrically arranged hinge blocks. One end of the hinge rod is hinged to the top of the hinge seat, and the other end is hinged to the hinge block. A guide rod is fixed to the inner wall of the groove. The slider has a guide hole for the guide rod to pass through. Two symmetrical fixing blocks are fixed to the outer wall of the heat sink. The fixing blocks are located on one side of the groove. The rear end of the hinge seat has a locking block. The front end of the fixing block has a locking groove for the locking block to be engaged.

[0009] Furthermore, a positioning assembly is provided inside the heat dissipation box. The positioning assembly includes a positioning rod, a guide block, and a positioning spring. The heat dissipation box has a sliding hole through which the positioning rod passes. One end of the positioning rod passes through the sliding hole and is fixed inside the heat dissipation box to a second heat-conducting block. The second heat-conducting block can abut against the top of the controller. A heat dissipation fin is fixed on one side of the second heat-conducting block. The guide block is welded and fixed inside the heat dissipation box by a connecting rod and is located at the upper end of the controller. The guide block has a guide hole through which the positioning rod passes. One end of the positioning rod passes through the sliding hole and extends to the outside of the heat dissipation box and is fixed to a stop block located outside the heat dissipation box. The positioning spring is sleeved on the positioning rod, and both ends of the positioning spring are fixed to the inner side of the stop block and the top of the heat dissipation box, respectively.

[0010] Furthermore, a pull ring is fixed to the outside of the stop block.

[0011] Furthermore, a drying component is provided inside the heat dissipation box. The drying component includes a mounting block and a water-absorbing sponge. The mounting block has a mounting groove, and the water-absorbing sponge is fitted into the mounting groove. A mounting hole is provided on one side of the heat dissipation box for the mounting groove to pass through. The mounting block can seal the mounting hole. The mounting block has protrusions on both sides. A fixing hole is provided on the inner wall of the heat dissipation box for the protrusions to be fitted into. The fixing hole is connected to the mounting hole, and one end of the fixing hole penetrates through the heat dissipation box.

[0012] Furthermore, two symmetrical retrieval holes are provided on the top of the mounting slot, and the retrieval holes are connected to the mounting slot. A pull rod located outside the heat sink is fixed on one side of the mounting block.

[0013] Furthermore, the outer wall of the ventilation duct has a pull groove, and the inner wall of the pull groove has a corrugated pattern. The pull groove and the corrugated pattern make it easier for the user to pull the ventilation duct.

[0014] Compared with the prior art, the advantages of the present invention are: This invention achieves air cooling for the controller by incorporating an air-cooling component, and by incorporating a water-cooling component, it can conduct and dissipate heat generated at the connection between the controller and the mounting plate. This effectively solves the problem in existing technologies where one side of the controller is directly fixed to the light fixture, and air cooling can only reach the other sides of the controller, resulting in uneven heat dissipation. The first heat-conducting block conducts heat away from the bottom of the controller and heats the cold water in the heat-conducting cavity. The heated water in the heat-conducting cavity flows into the heat-dissipating cavity, and the cold water in the heat-dissipating cavity flows into the heat-conducting cavity, achieving heat exchange within the heat-conducting cavity. The heat-dissipating block conducts heat away from the hot water in the heat-dissipating cavity, dissipating the heat. Heating the water surface creates thermal convection because heat causes expansion of substances, causing hot water to flow towards cooler areas. When water is heated, it heats at different rates, resulting in uneven heat distribution. Hotter water rises because it is lighter, while cooler water sinks, creating convection. In this process, heat can be transferred in the liquid through convection, ensuring a uniform temperature throughout the system. Meanwhile, the air-cooling component can perform air-cooling heat dissipation on the heat sink, realize heat exchange between the heat sink and the cold air, realize the cooling heat sink, reduce the water in the heat dissipation cavity, realize the water-cooling component can be recycled, and improve the utilization rate of the water-cooling component. This invention, by setting up a positioning component, a connecting component, an air-cooling component, and a mounting plate, allows for further positioning of the controller entering the heat sink. The second heat-conducting block and heat dissipation fins further enhance the controller's cooling effect. When disassembling the controller: first pull the pull ring, which, via the positioning rod, disengages the second heat-conducting block from the controller. Then, pull the ventilation cylinder to move the mounting plate outside the heat sink, allowing the controller to be removed from the mounting plate. This facilitates controller disassembly. The connecting component ensures the ventilation cylinder does not detach from the heat sink and limits its movement to the outside of the heat sink, preventing rotation and facilitating rapid installation of the ventilation cylinder into the through hole, and ensuring the limit block aligns with the limit hole. This invention uses a drying component to absorb moisture from the air inside the heat sink, ensuring the air inside the heat sink is dry, thereby protecting the controller from moisture and extending its service life.

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0025] like Figure 1 , 2As shown, the present invention relates to an automatic sensor-activated dimming lamp, comprising a dimming lamp body 1, a triangular support frame 2 fixed to the lower end of the dimming lamp body 1, a heat sink 3 fixed to one side of the dimming lamp body 1, a through hole 4 on one side of the heat sink 3, a wind-cooling component for blowing air into the heat sink 3 being fitted into the through hole 4, one end of the wind-cooling component extending outside the heat sink 3, the wind-cooling component drawing in cool air from the outside into the heat sink 3 and expelling hot air from the heat sink 3, thus achieving wind-cooling treatment, a connecting component being provided between the wind-cooling component and the side wall of the heat sink 3, the connecting component ensuring that the wind-cooling component is always connected to the heat sink 3 and will not fall off, a mounting plate 5 fixed to one end of the wind-cooling component that can pass through the through hole 4 and be fitted into the heat sink 3, a controller being detachably mounted on the mounting plate 5. 6. The mounting plate 5 is equipped with a water-cooling component for conducting heat from the controller 6. The heat generated at the connection surface between the bottom of the controller 6 and the mounting plate 5 can be conducted through the water-cooling component, preventing the heat generated at the connection surface between the bottom of the controller 6 and the mounting plate 5 from failing to be cooled. At the same time, the air-cooling component blows air onto the water-cooling component to achieve heat exchange between the water-cooling component and the cold air, thereby achieving cooling of the water-cooling component. This allows the water-cooling component to be recycled, improving its utilization rate. The air-cooling component can move the mounting plate 5 outside the heat sink 3. Moving the mounting plate 5 outside the heat sink 3 via the air-cooling component makes it easy to remove the controller 6, which is detachably mounted on the mounting plate 5, for maintenance or replacement. Ventilation holes are opened on both sides of the heat sink 3, and a dustproof mesh 7 is fixed to the inner wall of the ventilation holes.

[0026] like Figure 2 , 4 As shown, the air-cooled assembly includes a ventilation duct 8 and a motor 9. The ventilation duct 8 is fitted into the through hole 4. The outer wall of the ventilation duct 8 has symmetrically arranged limiting blocks 10. The heat dissipation box 3 has a limiting hole 11 for the guide block 29 to be fitted and connected to the through hole 4. The ventilation duct 8 can drive the limiting block 10 to move along the limiting hole 11. The mounting plate 5 is fixed to one end of the ventilation duct 8. The motor 9 is welded to the inner wall of the ventilation duct 8 through a connecting rod. The output shaft of the motor 9 is fixed with a fan blade 12. The inner wall of the ventilation duct 8 is fixed with a dustproof net 13 located at the front end of the fan blade 12. The outer wall of the ventilation duct 8 has a pulling groove 42, and the inner wall of the pulling groove 42 has a corrugated pattern.

[0027] like Figure 2 , 3As shown in Figure 5, the inner wall of the heat dissipation box 3 has a slot 14 for one end of the mounting plate 5 to be inserted. The water cooling assembly includes a first heat-conducting block 15. The top of the mounting plate 5 has a groove 16 for the bottom of the controller 6 to be inserted. The mounting plate 5 has a cavity. The first heat-conducting block 15 is fixed in the cavity. The groove 16 is connected to the cavity. The top of the first heat-conducting block 15 is in contact with the bottom of the controller 6. The top of the first heat-conducting block 15 has several symmetrically arranged U-shaped heat dissipation blocks 17 that pass through the mounting plate 5. The several heat dissipation blocks 17 are symmetrically arranged relative to the controller 6. The first heat-conducting block 15 has a heat-conducting cavity 18. The heat dissipation block 17 has a U-shaped heat dissipation cavity 19. The heat dissipation cavity 19 is connected to the heat-conducting cavity 18. The heat dissipation cavity 19 and the heat-conducting cavity 18 are filled with cold water. The first heat-conducting block 15 conducts heat away from the bottom of the controller 6 and heats the cold water in the heat-conducting cavity 18. The heated water in the heat-conducting cavity 18 flows into the heat dissipation cavity 19, and the cold water in the heat dissipation cavity 19 flows into the heat-conducting cavity 18, achieving heat exchange between the water in the heat-conducting cavity 18. The heat dissipation block 17 conducts heat away from the hot water in the heat dissipation cavity 19 and performs heat dissipation treatment. Heating the water surface will form thermal convection because heat causes the expansion of substances, causing hot water to flow to cooler areas. When water is heated, it heats at different rates, resulting in uneven heat distribution in the water. Hotter water rises because it is lighter, while colder water sinks, thus forming convection. In this process, heat can be transferred in the liquid through convection to achieve temperature equilibrium in the entire system.

[0028] like Figure 2 , 4 As shown in Figure 8, the connecting assembly includes two hinge rods 20 and two hinge seats 21. The bottom of the hinge seat 21 has a slider 22. One end of the outer wall of the heat sink 3 has a groove 23 for the slider 22 to be inserted. The outer wall of the ventilation duct 8 has symmetrically arranged hinge blocks 24. One end of the hinge rod 20 is hinged to the top of the hinge seat 21, and the other end is hinged to the hinge block 24. A guide rod 25 is fixed to the inner wall of the groove 23. The slider 22 has a guide hole for the guide rod 25 to pass through. Two symmetrical fixing blocks 26 are fixed to the outer wall of the heat sink 3. The fixing blocks 26 are located on one side of the groove 23. The rear end of the hinge seat 21 has a locking block 27. The front end of the fixing block 26 has a locking groove for the locking block 27 to be inserted.

[0029] like Figure 2 , 6As shown, a positioning assembly is provided inside the heat dissipation box 3. The positioning assembly includes a positioning rod 28, a guide block 29, and a positioning spring 30. The heat dissipation box 3 has a sliding hole through which the positioning rod 28 passes. One end of the positioning rod 28 passes through the sliding hole and is fixed inside the heat dissipation box 3 with a second heat-conducting block 31. The second heat-conducting block 31 can abut against the top of the controller 6. A heat dissipation fin 32 is fixed on one side of the second heat-conducting block 31. The second heat-conducting block 31 and the heat dissipation fin 32 together achieve heat dissipation for the controller 6. The guide block 29 is welded and fixed inside the heat sink 3 via a connecting rod and located at the upper end of the controller 6. The guide block 29 has a guide hole for the positioning rod 28 to pass through, and the guide block 29 limits the positioning rod 28 to prevent it from shifting during movement. One end of the positioning rod 28 extends through a sliding hole to the outside of the heat sink 3 and is fixed to a stop block 33 located outside the heat sink 3. The positioning spring 30 is sleeved on the positioning rod 28, and both ends of the positioning spring 30 are fixed to the inner side of the stop block 33 and the top of the heat sink 3, respectively. The function of the positioning spring 30 is to ensure that the second heat-conducting block 31 always abuts against the top of the controller 6 without external force. A pull ring 34 is fixed to the outer side of the stop block 33.

[0030] like Figure 2 , 7 As shown in Figure 8, a drying component is provided inside the heat sink 3. The drying component includes a mounting block 35 and a water-absorbing sponge 36. The mounting block 35 has a mounting groove, and the water-absorbing sponge 36 is fitted into the mounting groove. A mounting hole 37 is provided on one side of the heat sink 3 for the mounting groove to pass through. The mounting block 35 can seal the mounting hole 37. The mounting block 35 has protrusions 38 on both sides. A fixing hole 39 is provided on the inner wall of the heat sink 3 for the protrusions 38 to fit into. The fixing hole 39 is connected to the mounting hole 37, and one end of the fixing hole 39 penetrates through the heat sink 3. The water-absorbing sponge 36 can absorb the moisture contained in the air inside the heat sink 3, ensuring that the air inside the heat sink 3 is dry. Two symmetrical removal holes 40 are provided on the top of the mounting groove, and the removal holes 40 are connected to the mounting groove. A pull rod 41 located outside the heat sink 3 is fixed to one side of the mounting block 35.

[0031] The working principle of this invention is as follows: Installation of controller 6: Insert the bottom of controller 6 into the groove 16 of mounting plate 5, align the ventilation tube 8 with the through hole 4 and insert it. The ventilation tube 8 drives the hinge seat 21 to move through the hinge rod 20. The hinge seat 21 drives the slider 22 to move along the slide groove 23 until the locking block 27 at the rear end of the hinge seat 21 is inserted into the locking groove of the fixing block 26, thereby positioning the ventilation tube 8. The ventilation tube 8 drives the mounting plate 5 into the heat dissipation box 3. Pull the pull ring 34. The pull ring 34 drives the positioning rod 28 to move upward through the stop block 33. The positioning rod 28 drives the second heat conduction block 31 to move upward. The baffle stretches the positioning spring 30. The positioning spring 30 has a certain elastic potential energy when stretched until one end of the mounting plate 5 is inserted into the slot 14. Release the pull ring 34. The positioning spring 30 drives the stop block 33 to move downward. The stop block 33 drives the second heat conduction block 31 to move downward through the positioning rod 28, so that the second heat conduction block 31 abuts against the top of the controller 6, thereby further fixing the controller 6. Cooling of controller 6: The starting motor 9 drives the fan blade 12 to rotate, and the fan blade 12 draws cold air from the outside into the heat sink 3 to achieve air cooling of the air unit. The first heat conduction block 15 conducts away the heat generated at the bottom of controller 6 and heats the cold water in the heat conduction cavity 18. The heated water in the heat conduction cavity 18 flows into the heat sink 19, and the cold water in the heat sink 19 flows into the heat conduction cavity 18, realizing the heat exchange of the water in the heat conduction cavity 18. The heat sink 17 conducts away the heat of the hot water in the heat sink 19 and performs heat dissipation. At the same time, the air drawn by the fan blade 12 also performs air cooling on the surface of the heat sink 17, further accelerating the heat dissipation efficiency of the heat sink 17, accelerating the cooling speed of the water in the heat sink 19, improving the heat exchange quality between the water in the heat sink 19 and the heat conduction cavity 18, and improving the water cooling efficiency at the bottom of controller 6. Disassembly of controller 6: First, pull the pull ring 34. The pull ring 34 drives the second heat conduction block 31 to disengage from the controller 6 via the positioning rod 28. Then, pull the ventilation tube 8 to move the mounting plate 5 outside the heat sink 3. The ventilation tube 8 drives the two hinge seats 21 to move relative to each other and get closer via the two hinge rods 20. The locking block 27 at the rear end of the hinge seat 21 disengages from the locking groove of the fixing block 26. Finally, the controller 6 can be removed from the mounting plate 5.
