Description

Technical Field

[0001] This invention belongs to the field of industrial lighting technology, and particularly relates to a high heat dissipation LED industrial lighting lamp and its control method. Background Technology

[0002] Industrial lighting, or factory lighting design, encompasses indoor lighting, outdoor installation lighting, station and yard lighting, underground lighting, road lighting, security lighting, and obstacle lighting. A factory is a place that produces predetermined products, generally consisting of factory buildings, offices and other ancillary buildings, various outdoor installations, stations, yards, and roads. The illuminance values ​​for factory lighting design should be selected according to the provisions of the national standard GB50034-2004, "Standard for Lighting Design of Buildings." This standard specifies the illuminance values ​​for general lighting in sixteen major categories of industrial buildings. Illuminance standards for more specific workplaces in various factories should also be in accordance with the regulations of the relevant industry.

[0003] Most industrial lighting fixtures nowadays use LED light source boards. Especially when used in factories, dust can clog the heat dissipation vents, leading to poor heat dissipation, overheating, and potential damage. Since these fixtures are often installed at high positions, manual cleaning presents numerous challenges. For example, Chinese patent application number (CN202111546790.X) discloses a high-heat-dissipation explosion-proof LED industrial lighting fixture. This application achieves dust removal by vibrating a filter screen. However, it uses a sealed cylinder, piston block, and cam structure, relying on the thermal expansion of carbon dioxide gas to drive the cam to rotate and remove dust from the filter screen. However, the heat rises, easily accumulating on the top wall of the housing, affecting the piston block's reset and resulting in poor performance. Furthermore, the application uses self-heating air to dissipate heat through the sides of the housing, which is also ineffective, further causing heat accumulation on the inner top wall of the housing, again affecting the piston block's reset and impacting dust removal efficiency. These methods require improvement. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a high-heat-dissipation LED industrial lighting lamp and its control method, achieving high heat dissipation and good dust removal effect, thus avoiding the impact of dust on heat dissipation.

[0005] In view of this, the present invention provides a high heat dissipation LED industrial lighting lamp, comprising:

[0006] The lamp housing has a ring-shaped LED light source panel mounted on its bottom surface.

[0007] The heat dissipation mechanism is installed inside the lamp housing and is used for heat dissipation of the LED light source board;

[0008] The heat dissipation mechanism includes:

[0009] The heat dissipation channel runs vertically through the lamp housing from bottom to top, and the LED light source board is arranged around the bottom of the heat dissipation channel;

[0010] The first air guide assembly is installed on the inner wall of the heat dissipation channel located at the top of the lamp housing;

[0011] The heat dissipation vent is located on the side of the lamp housing;

[0012] The second air guide assembly is installed inside the lamp housing and is positioned corresponding to the heat dissipation vent.

[0013] The heat dissipation channel has an opening on its side, and the opening is set to correspond to the heat dissipation vent.

[0014] In this technical solution, a vertically arranged heat dissipation channel from bottom to top allows heat to be discharged from the top of the lamp housing, preventing heat from accumulating inside the lamp housing and ensuring heat dissipation. At the same time, heat dissipation vents are opened on the side, and a first air guide component and a second air guide component are set to accelerate air circulation, thereby improving the heat dissipation effect. In addition, accelerated air circulation makes it less likely for dust to accumulate, preventing dust from affecting the heat dissipation effect.

[0015] In the above technical solution, the second air guide component further includes:

[0016] The crossbeam is installed between the side of the heat dissipation channel and the inner wall of the lamp housing, and its two ends are respectively set to correspond to the opening and heat dissipation vent.

[0017] The support plate is installed on the bottom surface of the crossbeam, and a drive motor is installed at its bottom end.

[0018] The fan blades are mounted on the output end of the drive motor and are located at the end of the drive motor closest to the heat dissipation port.

[0019] In this technical solution, the installation strength of the drive motor is improved by setting a crossbeam and a support plate, and a fan blade is set on the output shaft of the drive motor. At the same time, the drive motor is placed between the opening and the heat dissipation port, so that the airflow direction is parallel to the direction between the opening and the heat dissipation port, ensuring the gas flow effect and heat dissipation effect. Meanwhile, placing the drive motor on the air outlet of the fan blade can dissipate heat from the drive motor, effectively removing the heat generated by the drive motor and improving the heat dissipation effect.

[0020] Furthermore, the above technical solution also includes:

[0021] The first dustproof screen is installed on the inner wall of the heat dissipation vent;

[0022] A dust removal assembly is installed on the first dust screen and is used for dust removal from the first dust screen.

[0023] The ash-vibrating component is driven by a drive motor.

[0024] In this technical solution, a first dustproof mesh is installed on the inner wall of the heat dissipation vent to prevent dust from entering the lamp housing. The dust is then removed by a dust-removing assembly after the dust has accumulated on the first dustproof mesh. The dust-removing assembly is driven by a drive motor, which reduces the number of drive devices. The structure is simple and the practical effect is good.

[0025] In the above technical solution, the ash-repellent assembly further includes:

[0026] A rotating block is connected to the output end of the drive motor;

[0027] The push block abuts against the side of the rotating block away from the drive motor;

[0028] The push rod has one end connected to the side of the push block near the first dustproof net, and the other end extends through the first dustproof net out of the lamp housing, and has a first protruding strip on its surface;

[0029] The striking head is installed at the end of the push rod located outside the lamp housing;

[0030] The teeth are circumferentially mounted on the side of the rotating block near the pushing block and on the side of the pushing block near the rotating block;

[0031] A spring is sleeved on the surface of the push rod and located between the push block and the first dustproof net;

[0032] The first dustproof net is provided with a collar sleeved on the surface of the push rod, and a first groove adapted to the first protrusion is opened on the inner wall of the collar. The teeth on the push block mesh with the teeth on the rotating block, and cooperate with the spring to push the push block to reciprocate along its axis.

[0033] In this technical solution, the drive motor drives the rotating block to rotate, which in turn pushes the push block intermittently to compress the spring through the teeth. This causes the push block to bounce back and forth in its axial direction, which in turn drives the striking head to strike the first dustproof net, cleaning the attached dust. The dust removal effect is good. The first protrusion and the first groove can limit the rotation of the push block, ensuring the reciprocating bounce of the push block and improving stability.

[0034] In the above technical solution, the ash-repelling assembly further includes:

[0035] A ratchet assembly is installed between the rotating block and the output end of the drive motor.

[0036] The ratchet component includes:

[0037] An insert groove is formed on the side of the rotating block near the drive motor, and the output end of the drive motor extends into the insert groove.

[0038] The ratchet teeth are circumferentially mounted on the inner wall of the groove.

[0039] The pawl is hinged to the end face of the drive motor output end near the embedded groove, and a torsion spring is provided at the hinge connection, which is adapted to the ratchet tooth.

[0040] In this technical solution, by employing a ratchet and pawl configuration, when the drive motor rotates to one side, it does not drive the rotating block to rotate, thus preventing the push block from reciprocating. At the same time, the airflow is directed inward, effectively dissipating heat in conjunction with the heat dissipation channel. When the drive motor rotates to the other side, it drives the rotating block to rotate, which in turn causes the push block to reciprocate, removing dust from the first dustproof net. Simultaneously, because the drive motor changes direction, the airflow is directed outward, further improving the dust removal effect on the first dustproof net. The embedded groove design facilitates improved connection stability between the pawl and ratchet, as well as installation stability of the ratchet component.

[0041] In the above technical solution, the second air guide component further includes:

[0042] Through holes are formed on the support plate;

[0043] The heat dissipation holes are located on the top wall of the lamp housing and are positioned corresponding to the crossbeam.

[0044] In this technical solution, by opening through holes in the support plate, the support plate is prevented from affecting the airflow between the heat dissipation port and the opening. The opening of the heat dissipation holes can prevent heat from accumulating at the top between the surface of the heat dissipation channel and the inner wall of the lamp housing, thus ensuring the heat dissipation effect.

[0045] In the above technical solution, the first air guide component further includes:

[0046] The fan is installed inside the heat dissipation channel;

[0047] The lower support bar is installed on the inner wall of the heat dissipation channel and is used to support the fan.

[0048] The second dust filter is installed at the top of the heat dissipation channel;

[0049] The third dustproof net is installed at the bottom of the heat dissipation channel;

[0050] The upper support bar is connected to the inner wall of the heat dissipation channel, with its top end connected to the second dust filter and its bottom end abutting against the fan.

[0051] The upper support bar has a second protrusion on the side near the inner wall of the heat dissipation channel, and the inner wall of the heat dissipation channel has a second groove that matches the second protrusion.

[0052] In this technical solution, the upper and lower support strips facilitate the installation and fixation of the fan, making installation convenient. Placing the fan on the inner wall of the heat dissipation channel accelerates airflow and improves heat dissipation, while also preventing dust from entering the heat dissipation channel from the top, thus providing a certain degree of dust prevention. The second protrusion and the second groove ensure the installation stability of the second dustproof mesh and the fan. The third dustproof mesh prevents dust from entering the lamp housing from the bottom, ensuring the dustproof effect of the inner wall of the lamp housing.

[0053] Furthermore, the above technical solution also includes:

[0054] Photosensitive switches are installed on the side of the fan near the second dust filter and on the top wall of the heat dissipation vent of the first dust filter near the heat dissipation channel.

[0055] Temperature control switch, which is installed inside the lamp housing on the bottom wall located at the LED light source board;

[0056] The control board is installed inside the lamp housing and is used to control the forward and reverse rotation of the drive motor.

[0057] In this technical solution, by employing photosensitive switches and temperature control switches, corresponding responses are made when the temperature rises due to excessive dust on the first and second dustproof screens. When there is excessive dust on the first dustproof screen, it can act as a start switch for the dust removal assembly, and when there is excessive dust on the second dustproof screen, it can provide an alarm. The control board facilitates the detection of the status of the photosensitive switches and temperature control switches, thereby driving and adjusting the rotation of the drive motor.

[0058] Furthermore, the above technical solution also includes:

[0059] The lampshade is mounted on the bottom surface of the lamp housing and includes a cover body and a skirt, with the cover body enclosing the LED light source board.

[0060] The lifting ring includes a connecting block mounted on the top surface of the lamp housing and a U-shaped frame hinged to the connecting block;

[0061] The connection between the connecting block and the U-shaped frame is equipped with a locking device for locking the rotation of the U-shaped frame.

[0062] In this technical solution, the lampshade provides protection for the LED light source board; the lifting ring facilitates the installation and removal of the lighting fixture; and the hinge connection between the connecting block and the U-shaped frame, as well as the locking mechanism, allows for adjustment of the lighting fixture's angle. The structure is simple and has good practical effect.

[0063] This invention provides a control method for a high-heat-dissipation LED industrial lighting lamp, comprising the following steps:

[0064] S1: Turn on the light switch, the LED light source board enters working mode, and the fan starts;

[0065] S2: The drive motor starts rotating forward, and the pawl does not drive the rotating block to rotate. The fan blades rotate, and the airflow is directed towards the heat dissipation channel side.

[0066] S3: Detect the status of the temperature control switch.

[0067] ①: When the temperature control switch is in the closed state, the status of the photosensitive switch is detected. If it is closed, it enters S4; if it is open, it enters S6.

[0068] ②: When the temperature control switch is in the off state, continuously monitor the status of the temperature control switch;

[0069] S4: After the drive motor stops, it reverses. The pawl drives the rotating block to rotate, and the dust removal component shakes off the dust on the first dust screen. At the same time, the airflow is directed towards the first dust screen to blow away the dust that has been shaken off the first dust screen.

[0070] S5: Detect the status of the photosensitive switch:

[0071] ①: The photosensitive switch is in the closed state, and the status of the photosensitive switch is continuously monitored;

[0072] ②: When the photosensitive switch is in the off state, the drive motor stops and returns to S2;

[0073] S6: The control panel turns off the lights and sends a feedback to the control center, indicating a lighting malfunction.

[0074] In this technical solution, the above control method enables the lighting lamp to automatically remove dust, preventing excessive dust accumulation on the first dustproof screen, especially when the second air guide component blows air into the heat dissipation channel, which would cause dust to accumulate too quickly. This allows for rapid and efficient removal of dust from the first dustproof screen, ensuring high heat dissipation. Furthermore, the dust removal component will not remove dust when the temperature does not exceed the set threshold, ensuring airflow between the heat dissipation vent and the opening, thus guaranteeing heat dissipation.

[0075] The beneficial effects of this invention are as follows:

[0076] 1. The heat dissipation channel is set vertically from bottom to top, so that heat can be discharged from the top of the lamp housing, avoiding heat accumulation at the top of the lamp housing and ensuring heat dissipation effect. At the same time, heat dissipation vents are opened on the side, and a first air guide component and a second air guide component are set to accelerate air circulation, thereby improving the heat dissipation effect. In addition, the accelerated air circulation will make it less likely for dust to accumulate, so as to avoid dust affecting the heat dissipation effect.

[0077] 2. The drive motor drives the rotating block to rotate, which in turn pushes the push block intermittently to compress the spring through the teeth. This causes the push block to bounce back and forth in its axial direction, which in turn drives the knocking head to knock on the first dustproof net to clean the attached dust. The dust removal effect is good. The first protrusion and the first groove can limit the rotation of the push block, ensure the reciprocating bounce of the push block, and improve stability.

[0078] 3. By employing a ratchet and pawl configuration, when the drive motor rotates to one side, it does not rotate the rotating block, thus preventing the push block from reciprocating. Simultaneously, the airflow is directed inward, effectively dissipating heat in conjunction with the cooling channel. When the drive motor rotates to the other side, it rotates the rotating block, causing the push block to reciprocate and remove dust from the first dust filter. Furthermore, the change in the direction of the drive motor directs the airflow outward, further enhancing the dust removal effect on the first dust filter. The embedded groove design facilitates improved connection stability between the pawl and ratchet, as well as the installation stability of the ratchet mechanism. Attached Figure Description

[0084] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0085] Example 1:

[0086] This embodiment provides a high heat dissipation LED industrial lighting lamp, including:

[0087] Lamp housing 1, with a ring-shaped LED light source board 2 mounted on the bottom surface of lamp housing 1;

[0088] A heat dissipation mechanism is installed inside the lamp housing 1 and is used for heat dissipation of the LED light source board 2;

[0089] The heat dissipation mechanism includes:

[0090] Heat dissipation channel 3 is vertically opened through the lamp housing 1 from bottom to top, and LED light source board 2 is arranged around the bottom of heat dissipation channel 3;

[0091] The first air guide assembly 4 is installed on the inner wall of the heat dissipation channel 3 located at the top of the lamp housing 1.

[0092] Heat dissipation vent 5 is located on the side of the lamp housing 1;

[0093] The second air guide assembly 6 is installed inside the lamp housing 1 and is set corresponding to the heat dissipation vent 5;

[0094] The heat dissipation channel 3 has an opening 30 on its side, and the opening 30 is corresponding to the heat dissipation port 5.

[0095] As can be seen from this embodiment, the heat dissipation channel 3, which is vertically arranged from bottom to top, allows heat to be discharged from the top of the lamp housing 1, preventing heat from accumulating inside the top of the lamp housing 1 and ensuring the heat dissipation effect. At the same time, heat dissipation vents 5 are opened on the side, and a first air guide component 4 and a second air guide component 6 are provided to accelerate air circulation, thereby improving the heat dissipation effect. In addition, accelerating air circulation will make it less likely for dust to accumulate, thus preventing dust from affecting the heat dissipation effect.

[0096] Example 2:

[0097] This embodiment provides a high heat dissipation LED industrial lighting lamp, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the second air guide component 6 includes:

[0098] The crossbeam 60 is installed between the side of the heat dissipation channel 3 and the inner wall of the lamp housing 1, and is respectively set at both ends to correspond to the opening 30 and the heat dissipation port 5.

[0099] Support plate 61 is installed on the bottom surface of crossbeam 60, and drive motor 62 is installed at its bottom end;

[0100] Fan blade 63 is mounted on the output end of drive motor 62 and is located at the end of drive motor 62 near heat dissipation port 5;

[0101] The crossbeam 60 and the heat dissipation channel 3 are preferably integrally formed, and the crossbeam 60 and the lamp housing 1 are preferably fixed with bolts. The support plate 61 and the crossbeam 60 are preferably fixed with bolts. The drive motor 62 and the support plate 61 are preferably connected by a snap-fit, that is, the support plate 61 is preferably provided with a slot on the side near the drive motor 62, and there are preferably two support plates 61. The drive motor 62 is set in the slot between the two support plates 61. The support plate 61 is also provided with a circular through hole 64 for the output shaft of the drive motor 62 to pass through. The fan blade 63 and the output shaft of the drive motor 62 are preferably connected by an interference fit.

[0102] As can be seen from this embodiment, by setting the crossbeam 60 and the support plate 61, the installation strength of the drive motor 62 is improved, and the fan blade 63 is set on the output shaft of the drive motor 62. At the same time, the drive motor 62 is set between the opening 30 and the heat dissipation port 5, so that the direction of its airflow is parallel to the direction between the opening 30 and the heat dissipation port 5, ensuring the gas flow effect and heat dissipation effect. Meanwhile, the drive motor 62 is set on the air outlet of the fan blade 63, which can dissipate heat from the drive motor 62, effectively removing the heat generated by the drive motor 62 and improving the heat dissipation effect.

[0103] Example 3:

[0104] This embodiment provides a high heat dissipation LED industrial lighting lamp, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and further includes:

[0105] The first dustproof net 7 is installed on the inner wall of the heat dissipation vent 5;

[0106] The dust removal assembly 8 is installed on the first dustproof net 7 and is used for dust removal from the first dustproof net 7;

[0107] Among them, the ash-removing assembly 8 is driven by the drive motor 62;

[0108] Meanwhile, the first dustproof net 7 is preferably made of metal, and is preferably connected to the lamp housing 1 by bolts.

[0109] As can be seen from this embodiment, by setting a first dustproof mesh 7 on the inner wall of the heat dissipation port 5, dust is prevented from entering the lamp housing 1. The dust is then removed by the dust-vibrating assembly 8 after the dust has accumulated on the first dustproof mesh 7. At the same time, the dust-vibrating assembly 8 is driven by the drive motor 62, which reduces the number of driving devices, resulting in a simple structure and good practical effect.

[0110] Example 4:

[0111] This embodiment provides a high heat dissipation LED industrial lighting lamp, which, in addition to the technical solutions of the above embodiments, also has the following technical features, wherein the dust removal assembly 8 includes:

[0112] Rotating block 80 is connected to the output end of drive motor 62;

[0113] Push block 81 abuts against the side of rotating block 80 away from drive motor 62;

[0114] Push rod 82, one end of push rod 82 is connected to the side of push block 81 near the first dustproof net 7, the other end extends through the first dustproof net 7 out of the lamp housing 1, and a first protrusion 820 is provided on the surface;

[0115] A striking head 83 is installed at the end of the push rod 82 located outside the lamp housing 1;

[0116] Tooth 84 is circumferentially mounted on the side of rotating block 80 near push block 81 and on the side of push block 81 near rotating block 80;

[0117] Spring 85 is sleeved on the surface of push rod 82 and located between push block 81 and first dustproof net 7;

[0118] The first dustproof net 7 is provided with a collar 9 sleeved on the surface of the push rod 82, and the inner wall of the collar 9 is provided with a first groove 90 that matches the first protrusion 820. The teeth 84 on the push block 81 mesh with the teeth 84 on the rotating block 80, and cooperate with the spring 85 to push the push block 81 to reciprocate along its axial direction.

[0119] Meanwhile, the rotating block 80 and its teeth 84 are preferably integrally formed, the pushing block 81 and its teeth 84, as well as the push rod 82 and the first protrusion 820 are preferably integrally formed, the two ends of the spring 85 abut against the pushing block 81 and the collar 9 respectively, and the striking head 83 can be a combination of a rubber ring and a nut, and the rubber ring is fixed by a threaded connection between the nut and the push rod 82. The rubber ring can avoid rigid impact on the first dustproof net 7 and improve its service life. The first dustproof net 7 is preferably made of metal.

[0120] As can be seen in this embodiment, the drive motor 62 drives the rotating block 80 to rotate, which in turn pushes the push block 81 intermittently to compress the spring 85 via the teeth 84. This causes the push block 81 to bounce back and forth in its axial direction, thereby driving the striking head 83 to strike the first dustproof net 7, cleaning the attached dust and achieving a good dust removal effect. The first protrusion 820 and the first groove 90 can restrict the rotation of the push block 81, ensuring the reciprocating bounce of the push block 81 and improving stability.

[0121] Example 5:

[0122] This embodiment provides a high heat dissipation LED industrial lighting lamp, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the dust removal assembly 8 further includes:

[0123] Ratchet 86 is installed between the rotating block 80 and the output end of the drive motor 62.

[0124] Among them, ratchet component 86 includes:

[0125] An embedding groove 860 is formed on the side of the rotating block 80 near the drive motor 62, and the output end of the drive motor 62 extends into the embedding groove 860.

[0126] Ratchet 861 is circumferentially mounted on the inner wall of the insertion groove 860;

[0127] Pawl 862 is hinged to the end face of the output end of drive motor 62 near the embedded groove 860, and a torsion spring is provided at the hinge connection, which is adapted to ratchet 861.

[0128] The ratchet 861 and the rotating block 80 are preferably integrally formed.

[0129] As can be seen from this embodiment, by using the ratchet 861 and pawl 862, when the drive motor 62 rotates to one side, it does not drive the rotating block 80 to rotate, and thus does not push the push block 81 to reciprocate. At the same time, the airflow is inward, which works in conjunction with the heat dissipation channel 3 to effectively dissipate heat. When the drive motor 62 rotates to the other side, it drives the rotating block 80 to rotate, which in turn pushes the push block 81 to reciprocate, removing dust from the first dustproof net 7. At the same time, because the drive motor 62 changes direction, the airflow is outward, which further improves the dust removal effect on the first dustproof net 7. The design of the embedded groove 860 facilitates the improvement of the connection stability between the pawl 862 and the ratchet 861, as well as the installation stability of the ratchet component 86.

[0130] Example 6:

[0131] This embodiment provides a high heat dissipation LED industrial lighting lamp, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the second air guide component 6 further includes:

[0132] Through hole 64 is provided on support plate 61;

[0133] Heat dissipation hole 65 is provided on the top wall of lamp housing 1 and is provided in correspondence with crossbeam 60.

[0134] As can be seen from this embodiment, by opening through holes 64 on the support plate 61, the support plate 61 is prevented from affecting the airflow between the heat dissipation port 5 and the opening 30. The opening of the heat dissipation hole 65 can prevent heat from depositing on the top between the surface of the heat dissipation channel 3 and the inner wall of the lamp housing 1, thus ensuring the heat dissipation effect.

[0135] Example 7:

[0136] This embodiment provides a high heat dissipation LED industrial lighting lamp, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the first air guide component 4 includes:

[0137] Fan 40 is installed inside the heat dissipation channel 3;

[0138] The lower support bar 41 is installed on the inner wall of the heat dissipation channel 3 and is used to support the fan 40.

[0139] The second dustproof net 42 is installed at the top of the heat dissipation channel 3;

[0140] The third dustproof net 43 is installed at the bottom of the heat dissipation channel 3;

[0141] The upper support bar 44 is connected to the inner wall of the heat dissipation channel 3, and its top end is connected to the second dustproof mesh 42, and its bottom end abuts against the fan 40.

[0142] Among them, the upper support bar 44 is provided with a second protrusion 45 on the side close to the inner wall of the heat dissipation channel 3, and the inner wall of the heat dissipation channel 3 is provided with a second groove 46 that matches the second protrusion 45.

[0143] Meanwhile, the second dustproof net 42 and the third dustproof net 43 are preferably made of metal and are preferably fixed by bolts. The lower support bar 41 and the heat dissipation channel 3 are preferably integrally formed, the upper support bar 44 and the second dustproof net 42 are preferably connected by bolts, and the upper support bar 44 and the second protruding bar 45 are preferably integrally formed.

[0144] As can be seen from this embodiment, the upper support bar 44 and the lower support bar 41 facilitate the installation and fixation of the fan 40, and the installation is convenient. The fan 40 is placed on the inner wall of the heat dissipation channel 3, which on the one hand accelerates the air circulation and improves the heat dissipation effect, and on the other hand prevents dust from entering the heat dissipation channel 3 from the top, thus playing a certain role in dust prevention. The second protrusion 45 and the second groove 46 ensure the installation stability of the second dustproof net 42 and the fan 40. The third dustproof net 43 can prevent dust from entering the lamp housing 1 from the bottom, thus ensuring the dustproof effect of the inner wall of the lamp housing 1.

[0145] Example 8:

[0146] This embodiment provides a high heat dissipation LED industrial lighting lamp, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and further includes:

[0147] Photosensitive switch 10 is installed on the side of fan 40 near the second dust filter 42 and on the top wall of the heat dissipation vent 5 of the first dust filter 7 near the heat dissipation channel 3.

[0148] Temperature control switch, which is installed inside lamp housing 1 on the bottom wall located at LED light source board 2;

[0149] The control board is installed inside the lamp housing 1 and is used to control the forward and reverse rotation of the drive motor 62.

[0150] In actual use, a control center should be set up to provide feedback through the control board. When too much dust accumulates on the first dustproof mesh 7, the photosensitive switch 10 will close because it cannot detect light, and open otherwise. The temperature control switch is normally open and will close when the temperature is higher than the threshold, and open otherwise.

[0151] As can be seen from this embodiment, by using a photosensitive switch 10 and a temperature control switch, the system can react accordingly when the temperature rises due to excessive dust on the first dustproof net 7 and the second dustproof net 42. When there is too much dust on the first dustproof net 7, it can act as a start switch for the dust removal assembly 8. When there is too much dust on the second dustproof net 42, it can provide an alarm. The control board can easily detect the status of the photosensitive switch 10 and the temperature control switch, thereby driving and adjusting the rotation of the drive motor.

[0152] Example 9:

[0153] This embodiment provides a high heat dissipation LED industrial lighting lamp, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and further includes:

[0154] The lampshade 11 is installed on the bottom surface of the lamp housing 1 and includes a cover body 110 and a skirt 111, and the cover body 110 surrounds the LED light source board 2.

[0155] The lifting ring 12 includes a connecting block 120 installed on the top surface of the lamp housing 1 and a U-shaped frame 121 hinged to the connecting block 120;

[0156] The connection between the connecting block 120 and the U-shaped frame 121 is provided with a locking element for locking the rotation of the U-shaped frame 121;

[0157] Meanwhile, the lampshade 11 is preferably connected to the bottom surface of the housing by bolts, the connecting block 120 is preferably integrally formed with the lamp housing 1, and the locking parts are preferably bolts and nuts, that is, tightening the nuts fixes the U-shaped frame 121 and the connecting block 120.

[0158] As can be seen from this embodiment, by setting the lampshade 11, it is easy to protect the LED light source board 2; while the hanging ring 12 facilitates the installation and removal of the lighting lamp. At the same time, the hinge connection between the connecting block 120 and the U-shaped frame 121 and the locking part can adjust the angle of the lighting lamp. The structure is simple and the practical effect is good.

[0159] Example 10:

[0160] This embodiment provides a control method for a high heat dissipation LED industrial lighting lamp, including the following steps:

[0161] S1: Turn on the light switch, LED light source board 2 enters working state, and fan 40 starts;

[0162] S2: Drive motor 62 starts to rotate forward, and pawl 862 does not drive rotating block 80 to rotate. Fan blade 63 rotates, and airflow is directed towards the heat dissipation channel 3.

[0163] S3: Detect the status of the temperature control switch.

[0164] ①: When the temperature control switch is in the closed state, the state of photosensitive switch 10 is detected. If it is closed, it enters S4; if it is open, it enters S6.

[0165] ②: When the temperature control switch is in the off state, continuously monitor the status of the temperature control switch;

[0166] S4: After the drive motor 62 stops, it reverses. The pawl 862 drives the rotating block 80 to rotate. The dust removal component 8 shakes off the dust on the first dustproof net 7. At the same time, the airflow is directed towards the first dustproof net 7, blowing away the dust that was shaken off the first dustproof net 7.

[0167] S5: Detect the status of photosensitive switch 10:

[0168] ①: The photosensitive switch 10 is in the closed state, and the state of the photosensitive switch 10 is continuously monitored;

[0169] ②: When the photosensitive switch 10 is in the off state, the drive motor 62 stops and returns to S2;

[0170] S6: The control panel turns off the lights and sends a feedback to the control center, indicating a lighting malfunction.

[0171] As can be seen from this embodiment, the above control method enables the lighting lamp to automatically remove dust, avoiding excessive dust accumulation on the first dustproof net 7, especially when the second air guide component 6 blows air into the heat dissipation channel 3, which would cause dust to accumulate too quickly. It can quickly and efficiently remove dust from the first dustproof net 7, ensuring high heat dissipation effect. Furthermore, when the temperature does not exceed the set threshold, the dust removal component 8 will not remove dust, ensuring airflow between the heat dissipation port 5 and the opening 30, thus ensuring heat dissipation effect.
