[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the implementation scope of the present invention is not limited thereto.

[0031] like Figures 1 to 11 As shown, a high-power street lamp with an independent cooling system described in this embodiment includes a lamp housing 1, a first bottom cover 2 and a second bottom cover 3 installed at the bottom of the lamp housing 1, the lamp housing 1 is fixedly installed on an external lamp pole, the first bottom cover 2 and the lamp housing 1 are surrounded to form a first space and a second space, and the second bottom cover 3 and the lamp housing 1 are surrounded to form a third space;

[0032] The first space is equipped with an air inlet and outlet valve connected to the second space; the second space is equipped with a lamp board 5 for providing lighting and a heat-conducting component for conducting the heat generated by the lamp board 5; the third space is equipped with a heat-conducting and heat-dissipating component; the second bottom cover 3 is provided with a heat-dissipating hole 31; one end of the heat-conducting component extends into the third space and is connected to the heat-conducting and heat-dissipating component; the lamp housing 1 is equipped with an airflow heat-dissipating component between the second space and the third space, the airflow heat-dissipating component is transmission-connected to the heat-conducting and heat-dissipating component, and the airflow heat-dissipating component is connected to the air inlet and outlet valve to discharge the hot air in the second space through the air inlet and outlet valve. The first space is connected to the outside environment, and the third space is connected to the outside environment through the heat-dissipating hole 31.

[0033] Specifically, when the high-power street lamp of this embodiment is actually used, the lamp board 5 is powered on to provide lighting, and the heat generated by the lamp board 5 is conducted to the heat-conducting and heat-dissipating component through the heat-conducting and heat-dissipating component. The heat-conducting and heat-dissipating component dissipates the conducted heat and discharges the hot air in the third space out of the housing through the heat dissipation holes 31. At the same time, the airflow heat-dissipating component, driven by the heat-conducting and heat-dissipating component, extracts the hot air in the second space and discharges it to the outside environment through the inlet and exhaust valve. At the same time, since the hot air in the second space is discharged, the cold air from the outside enters the second space through the inlet and exhaust valve, thereby cooling the temperature of the lamp board 5.

[0034] In this way, a cooling system is formed by a heat-conducting component, a heat-conducting heat-dissipating component, an airflow heat-dissipating component and an intake and exhaust valve, thereby forming a double heat-dissipating effect on the lamp board 5, improving the heat-dissipating efficiency, effectively meeting the heat-dissipating requirements of the high-power lamp board 5, and helping to extend the service life of the high-power street lamp.

[0035] like Figure 1 , Figure 3 and Figure 4 As shown, in the high-power street lamp described in this embodiment, in some embodiments, the heat conduction assembly includes a heat conduction plate 61 attached to the lamp board 5 and a plurality of heat conduction pipes 62 arranged at intervals; one end of the heat conduction pipe 62 is embedded in the heat conduction plate 61, so that the heat on the heat conduction plate 61 can be fully transferred to the heat conduction and heat dissipation assembly through the heat conduction pipe 62 to improve the heat conduction efficiency, and the other end of the heat conduction pipe 62 extends into the third space; the heat conduction and heat dissipation assembly is connected to the other end of the heat conduction pipe 62. The plurality of heat conduction pipes 62 are arranged at equal intervals.

[0036] In actual use, the heat conducting plate 61 fully absorbs the heat generated by the lamp board 5 and conducts the absorbed heat to the heat dissipation component through each heat conducting pipe 62, so that the heat is dissipated through the heat dissipation component to achieve a cooling effect on the lamp board 5.

[0037] like Figure 1 , Figures 3 to 5 As shown, in some embodiments of the high-power street lamp described in this embodiment, the heat conduction and heat dissipation assembly includes a power member 71 installed on the second bottom cover 3, a heat dissipation fan blade 72 connected to the output end of the power member 71, and a plurality of heat dissipation fins 73 arranged above the heat dissipation blades at intervals; each heat dissipation fin 73 is fixedly sleeved with each heat conduction pipe 62; the heat dissipation fan blade 72 is transmission-connected to the airflow heat dissipation assembly to drive the airflow heat dissipation assembly to discharge the hot air in the second space through the intake and exhaust valves. The power member 71 is a motor, and the heat dissipation fan blade 72 is installed at the position corresponding to the heat dissipation hole 31.

[0038] In actual use, by setting up multiple heat sinks 73, the heat dissipation area of ​​the heat pipe 62 is increased to facilitate rapid heat dissipation to ensure the thermal conductivity of the heat pipe 62. The power part 71 drives the heat dissipation blades 72 to rotate, and the heat dissipation blades 72 face the airflow, so that the hot air in the third space is discharged to the external environment through the heat dissipation holes 31, so that the heat of the heat sink 73 can be quickly dissipated, and the temperature of the heat sink 73 can be quickly reduced, thereby keeping the thermal conductivity of the heat pipe 62 stable and improving the heat dissipation efficiency.

[0039] like Figures 1 to 8 As shown, the high-power street lamp described in this embodiment, in some embodiments, the airflow heat dissipation component includes an air pump 81; the air pump 81 includes a pump body 811 and a piston 812, the pump body 811 has a pump cavity, the piston 812 is sealingly slidably arranged in the pump cavity, an air chamber 813 is enclosed and formed between the piston 812 and the pump body 811, the pump body 811 is provided with an air inlet hole 8111 and an exhaust hole 8112 connected to the air chamber 813, the air inlet hole 8111 is connected to the second space, and the exhaust hole 8112 is connected to the air inlet and exhaust valves; an air inlet check valve 814 is provided in the air inlet hole 8111, and an exhaust check valve 815 is provided in the exhaust hole 8112; the piston 812 is transmission-connected to the heat dissipation fan blades 72 so as to make reciprocating motion driven by the heat dissipation blades.

[0040] In actual use, the motor drives the heat dissipation fan blades 72 to rotate, and the heat dissipation fan blades 72 drive the piston 812 to reciprocate. During the reciprocating motion of the piston 812, when the effective volume of the air chamber 813 increases, the pressure of the air chamber 813 decreases, so that the intake check valve 814 opens and the exhaust check valve 815 closes, and the hot air in the second space is sucked into the air chamber 813 through the air inlet hole 8111; when the effective volume of the air chamber 813 decreases, the pressure of the air chamber 813 increases, so that the intake check valve 814 closes and the exhaust check valve 815 opens, and the hot air in the air chamber 813 is discharged to the external environment through the intake and exhaust valves. Since part of the hot air in the second space is discharged into the air chamber 813, the pressure is reduced, and the external cold air enters the second space through the intake and exhaust valves, thereby replenishing the air in the second space and cooling the second space at the same time, thereby achieving the airflow heat dissipation effect, combining the heat dissipation of the heat conductive component and the heat conductive heat dissipation component, and efficiently dissipating the light board 5.

[0041] like Figures 3 to 6 As shown, in the high-power street lamp described in this embodiment, in some embodiments, the airflow heat dissipation component includes two air pumps 81 arranged side by side and spaced apart, and the pistons 812 of the two air pumps 81 move synchronously in opposite directions; the airflow heat dissipation component also includes an air outlet tank 82 arranged between the two air pumps 81; the exhaust holes 8112 of the two air pumps 81 are both connected to the air outlet tank 82, and the air outlet tank 82 is connected to the air inlet and exhaust valves.

[0042] In this embodiment, two air pumps 81 are provided. Driven by the heat-conducting and heat-dissipating components, the two air pumps 81 reciprocate and alternately pump the hot air in the second space 81 into the air outlet tank 82, and then discharge it into the external environment through the air outlet tank 82 through the air inlet and exhaust valves, thereby further improving the heat dissipation efficiency.

[0043] like Figure 4 and Figure 5 As shown, in some embodiments of the high-power street lamp described in this embodiment, the heat dissipation blade 72 is connected to an incomplete gear 91, and a sliding frame 92 is slidably connected above the heat dissipation blade 72 in the lamp housing 1. The two opposite inner side walls of the sliding frame 92 are provided with tooth structures 921. The incomplete gear 91 is located in the sliding frame 92. During the rotation process, the incomplete gear 91 can alternately mesh with the tooth structures 921 on both sides of the sliding frame 92 to drive the sliding frame 92 to slide back and forth; the piston 812 is extended with a plug rod 8121, and the plug rod 8121 is connected to a transmission plate 8122 in the third space, and the transmission plate 8122 is provided with an oblique bar hole 8123; driving pins 922 are provided at both ends of the sliding frame 92, and the driving pins 922 are movably embedded in the corresponding oblique bar holes 8123. The oblique bar holes 8123 of the two transmission plates 8122 are arranged in an eight-shaped shape.

[0044] Specifically, for the convenience of explaining this embodiment, one air pump 81 is defined as air pump No. 1 81, and the other air pump 81 is defined as air pump No. 2 81; in actual use, the motor drives the heat dissipation fan blades 72 to rotate, and the heat dissipation fan blades 72 drive the incomplete gear 91 to rotate. When the incomplete gear 91 is engaged with the tooth structure 921 on one side of the sliding frame 92, the incomplete gear 91 drives the sliding frame 92 to slide toward one side. During the sliding process, the sliding frame 92 cooperates with the inclined bar hole 8123 through the driving pin 922 to drive the two pistons 812 to move synchronously in opposite directions, so that the No. 1 air pump 81 sucks the hot air in the second space into the air chamber 813, and the No. 2 air pump 81 discharges the hot air in the air chamber 813 into the air outlet tank 82. At the same time, the external cold air enters the second space through the inlet and exhaust valves, thereby The second space is cooled; when the incomplete gear 91 is meshed with the tooth structure 921 on the other side of the sliding frame 92, the incomplete gear 91 drives the sliding frame 92 to slide toward the other side, and the sliding frame 92 cooperates with the inclined hole 8123 through the driving pin 922 to drive the two pistons 812 to move in opposite directions synchronously. At this time, the No. 1 air pump 81 discharges the hot air in the air chamber 813 into the air outlet tank 82, and the No. 2 air pump 81 sucks the hot air in the second space into the air chamber 813. At the same time, the external cold air enters the second space through the air inlet and exhaust valves, thereby cooling the second space; in this way, during the reciprocating motion of the sliding frame 92 driven by the incomplete gear 91, the two air pumps 81 alternately extract the hot air in the second space, so that the heat dissipation airflow can be continuously generated in the second space, thereby improving the heat dissipation efficiency.

[0045] like Figures 1 to 4 , Figures 9 to 11 As shown, in the high-power street lamp described in this embodiment, in some embodiments, the air inlet and outlet valve includes a valve body 41 having a valve cavity, a valve core 42 is slidably arranged in the valve cavity, and independent filter cavities are respectively arranged at both ends of the valve core 42, and the filter cavity is filled with an activated carbon filter layer 43; two air inlet and outlet through holes 411 are arranged on one side of the valve body 41, and two air exhaust through holes 412 and two air inlet through holes 413 located between the two air exhaust through holes 412 are arranged on the other side of the valve body 41, the two air inlet through holes 413 are respectively connected to the second space, and the two air exhaust through holes 412 are respectively connected to the air outlet tank 82 through the conduit 44; strip holes connected to the corresponding filter cavities are respectively arranged on both sides of the valve core 42 corresponding to the two filter cavities;

[0046] The two inlet and outlet holes 411 are connected to the filter chamber through the strip hole on one side of the valve core 42; the two inlet and outlet holes 411, the two exhaust holes 412, the two air inlet holes 413 and the two filter chambers constitute two groups of inlet and outlet channels, when one group of inlet and outlet channels delivers cold air to the second space, the other group of inlet and outlet channels discharges hot air.

[0047] In order to facilitate the explanation of this embodiment, one group of inlet and outlet channels is defined as No. 1 inlet and outlet channels, and the other group of inlet and outlet channels is defined as No. 2 inlet and outlet channels; specifically, when No. 1 inlet and outlet channels are in a working state of conveying cold air to the second space, No. 2 inlet and outlet channels are in a working state of discharging hot air, and No. 1 air pump 81 sucks the hot air in the second space into the air chamber 813. At this time, the pressure in the second space is reduced, and the external cooling air enters the filter cavity of No. 1 inlet and outlet channels through the inlet and outlet holes 411 of No. 1 inlet and outlet channels. After being dried by the activated carbon filter layer 43 in the filter cavity, the moisture in the external cooling air is absorbed by the activated carbon filter layer 43 to prevent the moisture in the external cooling air from oxidizing and corroding the internal circuit. The external cooling air enters the second space through the air inlet holes 413 of No. 1 inlet and outlet channels, thereby cooling the second space.

[0048] At the same time, the No. 2 air pump 81 discharges the hot air in the air chamber 813 into the air outlet tank 82. The hot air is discharged from the air outlet tank 82 to the exhaust through hole 412 of the No. 2 inlet and outlet channel through the conduit 44, enters the filter cavity of the No. 2 inlet and outlet channel through the exhaust through hole 412 of the No. 2 inlet and outlet channel, and then is discharged to the outside environment from the inlet and outlet through hole 411 of the No. 2 inlet and outlet channel. When the hot air passes through the activated carbon filter layer 43 in the filter cavity of the No. 2 inlet and outlet channel, it drives the water inside the activated carbon filter layer 43 to evaporate, so that the activated carbon filter layer 43 in the filter cavity can be repeatedly used alternately, thereby reducing maintenance costs.

[0049] When it is necessary to switch the working status of the two sets of inlet and exhaust channels, the valve core 42 slides relative to the valve body 41, so that the No. 1 inlet and exhaust channel is in a working state of exhausting hot air, and the No. 2 inlet and exhaust channel is in a working state of delivering cold air to the second space. In this way, the outside cold air enters the second space through the No. 2 inlet and exhaust channel, and the hot air in the air outlet tank 82 is discharged to the outside environment through the No. 1 inlet and exhaust channel. In this way, heat dissipation is circulated in the second space, thereby improving the heat dissipation efficiency and adapting to the heat dissipation requirements of the high-power lamp panel 5.

[0050] like Fig.10 and Fig.11 As shown, in some embodiments of the high-power street lamp described in this embodiment, a permanent magnet 451 is provided at one end of the valve core 42, and an electromagnet 452 is provided on the inner wall of the valve cavity opposite to the permanent magnet 451. In this embodiment, by providing the permanent magnet 451 and the electromagnet 452, when it is necessary to switch the working state of the two groups of inlet and outlet channels, the electromagnet 452 is energized to generate a magnetic attraction force or a magnetic repulsion force on the permanent magnet 451, so that the permanent magnet 451 drives the valve core 42 to move toward or away from the electromagnet 452, thereby realizing the switching of the working state of the two groups of inlet and outlet channels.

[0051] like Fig.10 As shown, in some embodiments of the high-power street lamp described in this embodiment, a humidity sensor 453 is provided at the top of the valve core 42 at positions corresponding to the two filter chambers. In this embodiment, the humidity sensor 453 is provided to detect the humidity of the activated carbon filter layer 43. When the humidity of the activated carbon filter layer 43 exceeds a preset threshold, the electromagnet 452 is energized, so that the inlet and outlet channels in the working state of delivering cold air to the second space are switched to the working state of discharging hot air, and the inlet and outlet channels in the working state of discharging hot air are switched to the working state of delivering cold air to the second space, thereby effectively ensuring the humidity of the second space and effectively preventing the moisture in the external cooling air from oxidizing and corroding the internal circuit.

[0052] like Fig.10As shown, in some embodiments of the high-power street lamp described in this embodiment, a swing rod 461 is hinged in the middle of the top wall in the valve cavity, and a telescopic block 462 is slidably connected to the end of the swing rod 461. A spring 463 is connected between one end of the telescopic block 462 and the swing rod 461, and the other end of the telescopic block 462 is hinged to the valve core 42. Specifically, when the valve core 42 slides from one side to the other side, the valve core 42 drives the swing rod 461 to swing through the telescopic block 462, and the telescopic block 462 compresses the spring 463 until the center line of the swing rod 461 swings to coincide with the center section of the valve body 41, and the compression of the spring 463 reaches the maximum. As the swing rod 461 continues to swing, the compression of the spring 463 gradually decreases, thereby applying a thrust to the valve core 42 through the telescopic block 462, so that the valve core 42 can reliably slide into place, ensuring the working state switching of the two groups of inlet and outlet channels, and the structure is more reliable.

[0053] The above is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the protection scope of the patent application of the present invention.
