Description

Technical Field

[0001] The present invention relates to the technical field of LED lighting equipment, and in particular to a high-power LED lighting equipment with high heat dissipation. Background Art

[0002] LED, or light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. The heart of the LED is a semiconductor chip, one end of which is attached to a bracket. One end is the negative pole, and the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated with epoxy resin. Existing high-power LED lighting equipment has high power and generates a lot of heat at the lamp base during operation. Therefore, workers will install heat dissipation fins at the lamp base to dissipate the heat generated. However, when the air flow direction is single or the air flow is not smooth, the heat emitted by the heat dissipation fins cannot be fully carried away by the airflow, resulting in a significant reduction in the heat dissipation effect. Summary of the Invention

[0003] In response to the shortcomings of the existing technology, the present invention provides a high-power LED lighting device with high heat dissipation performance, which solves the problem in the existing technology that when the air flow direction is single or the air flow is not smooth, the heat emitted by the heat dissipating fins cannot be fully carried away by the airflow, resulting in a significant reduction in the heat dissipation effect.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0005] A high-power LED lighting device with high heat dissipation performance comprises a lamp holder, a lampshade is fixedly mounted on the lower end of the lamp holder, an LED lighting lamp is arranged on the lower end of the lamp holder and inside the lampshade, a connecting rod is fixedly mounted on the upper end of the lamp holder, a mounting plate is fixedly mounted on the upper end of the connecting rod, and connecting holes are formed on both sides of the upper surface of the mounting plate;

[0006] The lamp holder body is provided with a heat dissipation sleeve, one side of the heat dissipation sleeve body is integrated with a plurality of heat dissipation fins, and the other side of the heat dissipation sleeve body is provided with a blowing component for blowing cooling airflow to the heat dissipation fins.

[0007] Preferably, the blowing assembly includes an annular plate, which is sleeved on the other side of the heat dissipation sleeve body, and an annular groove is provided on the surface of the annular plate body, and a plurality of ventilation slots are provided on the bottom surface of the annular groove;

[0008] The annular plate body is provided with a sealing sleeve, the inner wall surface of the sealing sleeve is penetrated by a through groove, the sealing sleeve is covered with a mounting frame fixedly installed at the position of the through groove, and a cooling fan is fixedly installed in the mounting frame.

[0009] Preferably, a guide sleeve is provided on the inner wall of the annular groove, and the surface of the guide sleeve is configured as an arc surface.

[0010] Preferably, a rotating shaft is rotatably mounted on both sides of the inner wall of each ventilation slot, and a guide plate is fixedly mounted between every two adjacent rotating shafts;

[0011] Each of the rotating shaft bodies is sleeved with an elastic member capable of bending and resetting, one end of each of the elastic members is fixedly connected to the corresponding guide plate, and the other end of each of the elastic members is fixedly connected to one side of the inner wall of the corresponding ventilation slot.

[0012] Preferably, the elastic member is a torsion spring.

[0013] Preferably, each of the guide plates is provided with a mounting groove on a side close to the lamp holder, and a first magnetic strip is fixedly installed in each of the mounting grooves;

[0014] A second magnetic strip is fixedly mounted on a side of the inner wall of each ventilation slot opposite to the first magnetic strip, and each of the first magnetic strips is arranged with the same polarity as the opposite second magnetic strip.

[0015] Preferably, a triangular block is fixedly mounted on a side of each guide plate close to the corresponding second magnetic strip.

[0016] Preferably, the guide plate and the triangular block are both made of polyvinyl chloride plastic material.

[0017] Preferably, a heat conducting rod is fixedly installed between every two adjacent heat dissipation fins, and each of the heat conducting rods is respectively arranged under the corresponding ventilation slot.

[0018] Preferably, each heat-conducting rod body is fixedly mounted with a plurality of heat-conducting rods.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When the external airflow is not smooth or the flow direction is single, the staff will activate the blowing component to blow low-temperature air to the heat dissipation fins. The airflow flows through the gaps between adjacent heat dissipation fins and takes away the heat around the heat dissipation fins. This avoids the situation in which the heat generated by the lamp holder is discharged by the heat dissipation fins and the heat is not able to be taken away by the airflow in an environment with poor air flow or a single air flow direction. This greatly improves the heat dissipation performance.

[0021] 2. By setting a guide sleeve with an arc surface on the sleeve body, the airflow blown out by the cooling fan can flow to the ventilation groove position through the arc surface of the guide sleeve, and finally flow to the gap between adjacent cooling fins through the ventilation groove, thereby avoiding irregular flow of the airflow after colliding with the inner wall of the annular groove, improving the utilization rate of the airflow, and allowing the airflow to more fully take away the heat around the cooling fins.

[0022] 3. When the airflow moves along the arc surface of the guide sleeve, it will blow the guide plate, causing the guide plate to rotate based on the rotating shaft. The torsion spring is deformed under force, and the guide plate is tilted, so that part of the airflow can be guided by the guide plate when passing through the ventilation slot, thereby increasing the flow range of the airflow and the heat dissipation range of the airflow to the heat dissipation fins. After the cooling fan stops working, the torsion spring resets and drives the guide plate to rotate in the opposite direction to its original position based on the rotating shaft. There is no need for manual reset by the staff, which reduces the workload of the staff.

[0023] 4. When the guide plate rotates with the shaft as the reference, the first magnetic stripe arranged in the mounting groove approaches the position of the second magnetic stripe, and the first magnetic stripe and the second magnetic stripe are arranged with the same pole. Therefore, when the first magnetic stripe approaches the second magnetic stripe, the second magnetic stripe will give the first magnetic stripe a repulsive force. Under the coordinated action of the repulsive force, the torsion spring and the airflow, the guide plate swings with the shaft as the reference, thereby further increasing the heat dissipation range of the airflow to the heat dissipation fins.

[0033] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] like Figure 1-8 As shown, a high-power LED lighting device with high heat dissipation performance includes a lamp holder 1, a lampshade 2 is fixedly installed at the lower end of the lamp holder 1, an LED lighting lamp 4 is arranged at the lower end of the lamp holder 1 and inside the lampshade 2, a connecting rod 5 is fixedly installed at the upper end of the lamp holder 1, a mounting plate 6 is fixedly installed at the upper end of the connecting rod 5, and connecting holes 601 are opened on both sides of the upper surface of the mounting plate 6.

[0035] The lamp holder 1 is provided with a heat dissipation sleeve 7 , one side of which is integrated with a plurality of heat dissipation fins 701 , and the other side of which is provided with a blowing assembly 3 for blowing cooling air to the heat dissipation fins 701 .

[0036] Through the above technical solution, when in use, the staff first makes the fastening bolts match with the connecting holes 601 so as to install the mounting plate 6 in the working position, and then the staff turns on the LED lighting lamp 4 to make it light up and perform lighting work. When the LED lighting lamp 4 starts to work, the heat dissipation fins 701 conduct the heat generated by the lamp holder 1 to the outside world. When the external airflow is not smooth or the flow direction is single, the staff activates the blowing assembly 3 to blow low-temperature airflow to the heat dissipation fins 701. The airflow flows through the gaps between adjacent heat dissipation fins 701 and takes away the heat around the heat dissipation fins 701, avoiding the situation in which, in an environment with poor air flow or a single air flow direction, the heat generated by the lamp holder 1 is extracted by the heat dissipation fins 701, and the heat is gathered around the heat dissipation fins 701 and cannot be taken away by the airflow, thereby greatly improving the heat dissipation performance.

[0037] like Figure 2-4 As shown, in this embodiment, the blowing assembly 3 includes an annular plate 301, which is sleeved on the other side of the heat dissipation sleeve 7. An annular groove 302 is provided on the surface of the annular plate 301, and a plurality of ventilation grooves 303 are provided through the bottom surface of the annular groove 302.

[0038] The annular plate 301 is fitted with a sealing sleeve 304, which has a through-slot 305 extending through its inner wall. A mounting frame 306 is fixedly mounted on the sealing sleeve 304, positioned in the slot 305. A cooling fan 307 is fixedly mounted within the mounting frame 306. When the cooling fan 307 is activated, it generates a high-flow, low-temperature airflow, which then enters the annular groove 302. Driven by the fluidity of the airflow, it flows through the ventilation slots 303 into the gap between two adjacent cooling fins 701, removing the heat accumulated around the cooling fins 701 and significantly improving heat dissipation performance.

[0039] like Figure 2-4 As shown, it should be noted that the inner wall of the annular groove 302 is provided with a guide sleeve 308, and the surface of the guide sleeve 308 is configured as an arc surface. By providing the guide sleeve 308 with an arc surface, the airflow blown out by the cooling fan 307 can flow through the arc surface of the guide sleeve 308 to the ventilation groove 303, and finally flow through the ventilation groove 303 to the gap between adjacent heat dissipation fins 701, thereby preventing the airflow from colliding with the inner wall of the annular groove 302 and flowing irregularly. This improves the utilization rate of the airflow and enables the airflow to more fully remove the heat around the heat dissipation fins 701.

[0040] like Figure 2 、 Figure 3 、 Figure 5 As shown, in a specific configuration, a rotating shaft 309 is rotatably mounted on both sides of the inner wall of each ventilation slot 303 , and a guide plate 3010 is fixedly mounted between every two adjacent rotating shafts 309 .

[0041] Each rotating shaft 309 is sleeved with an elastic member 3011 that can bend and reset. One end of each elastic member 3011 is fixedly connected to the corresponding guide plate 3010, and the other end of each elastic member 3011 is fixedly connected to one side of the inner wall of the corresponding ventilation slot 303.

[0042] The elastic member 3011 is a torsion spring. When airflow moves along the curved surface of the guide sleeve 308, it blows against the guide plate 3010, causing it to rotate about the rotating shaft 309. The torsion spring is deformed by the force, causing the guide plate 3010 to tilt, thereby allowing part of the airflow to be guided by the guide plate 3010 when passing through the ventilation slots 303. This increases the flow range of the airflow and the heat dissipation range of the airflow to the heat dissipation fins 701. After the cooling fan 307 stops working, the torsion spring resets and drives the guide plate 3010 to rotate back to its original position about the rotating shaft 309, eliminating the need for manual reset by staff and reducing their workload.

[0043] like Figure 2 、 Figure 7 、 Figure 8 As shown, it can be understood that in the present application, each guide plate 3010 is provided with a mounting groove 3012 on a side close to the lamp holder 1 , and a first magnetic strip 3013 is fixedly installed in each mounting groove 3012 .

[0044] A second magnetic strip 3014 is fixedly mounted on the inner wall of each ventilation slot 303 on a side opposite to the first magnetic strip 3013 , and each first magnetic strip 3013 is arranged with the same polarity as the opposite second magnetic strip 3014 .

[0045] A triangular block 3015 is fixedly mounted on one side of each guide plate 3010 close to the corresponding second magnetic strip 3014 .

[0046] The guide plate 3010 and the triangular block 3015 are both made of polyvinyl chloride plastic material.

[0047] When the guide plate 3010 rotates with the rotating shaft 309 as the reference, the first magnetic strip 3013 set in the installation groove 3012 is close to the position of the second magnetic strip 3014, and the first magnetic strip 3013 and the second magnetic strip 3014 are set with the same pole. Therefore, when the first magnetic strip 3013 is close to the second magnetic strip 3014, the second magnetic strip 3014 will give the first magnetic strip 3013 a repulsive force. Under the coordinated action of the repulsive force, the torsion spring and the airflow, the guide plate 3010 swings with the rotating shaft 309 as the reference, thereby further increasing the heat dissipation range of the airflow on the heat dissipation fins 701.

[0048] By providing the triangular blocks 3015 , the airflow along the guide plate 3010 can be diverted by the triangular blocks 3015 , so that the surface of the heat dissipating fins 701 can be more fully in contact with the airflow, thereby allowing the airflow to more fully remove the heat.

[0049] Polyvinyl chloride has the advantage of being lightweight. By setting the material of the guide plate 3010 and the triangular block 3015 to polyethylene material, the guide plate 3010 with the triangular block 3015 on the surface can be easily rotated under the action of external force, avoiding the situation where the material is too heavy, resulting in the guide plate 3010 being unable to rotate and the diversion work being unable to be performed.

[0050] like Figure 2 、 Figure 3 、 Figure 6 As shown, in a specific configuration, a heat conducting rod 8 is fixedly installed between every two adjacent heat dissipation fins 701 , and each heat conducting rod 8 is respectively arranged below the corresponding ventilation slot 303 .

[0051] Each heat conducting rod 8 is fixedly mounted with a plurality of heat conducting rods 801. By placing the heat conducting rod 8 and the heat conducting rod 801 between two adjacent heat dissipating fins 701 and placing them below the ventilation slots 303, the heat conducting rod 8 and the heat conducting rod 801 can fully absorb and conduct heat from the heat dissipating fins 701. The heat absorbed by the heat conducting rod 8 can be promptly carried away by the airflow flowing out of the ventilation slots 303, thereby increasing the contact area between the heat dissipating fins 701 and the airflow, further enhancing the heat dissipation effect.

[0052] The working principle of a high-power LED lighting device with high heat dissipation:

[0053] When in use, first, the staff makes the fastening bolts match with the connecting holes 601 to install the mounting plate 6 in the working position, and then the staff turns on the LED lighting lamp 4 to make it light up and perform lighting work. When the LED lighting lamp 4 starts to work, the heat dissipation fins 701 conduct the heat generated by the lamp holder 1 to the outside. When the external airflow is not smooth or the flow direction is single, the staff activates the blowing assembly 3 to blow low-temperature airflow to the heat dissipation fins 701. The airflow flows through the gaps between adjacent heat dissipation fins 701 and takes away the heat around the heat dissipation fins 701, avoiding the situation in which, in an environment with poor air flow or a single air flow direction, the heat generated by the lamp holder 1 is discharged by the heat dissipation fins 701, and the heat is gathered around the heat dissipation fins 701 and cannot be taken away by the airflow, thereby greatly improving the heat dissipation performance.

[0054] The above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to enumerate all the implementation methods here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
