Abstract
Description
Technical Field
[0001] The present invention relates to the field of lighting fixtures, and specifically to an LED floodlighting fixture. Background Art
[0002] An LED floodlight is a point light source that can uniformly irradiate in all directions, and the irradiation range can be adjusted arbitrarily. LED floodlighting is a lighting method that uses this light source to focus on illuminating the exterior of buildings or other scenes at night, aiming to highlight the characteristics and artistic effects of the illuminated objects.
[0003] In the prior art, for example, a Chinese utility model patent (authorized publication number CN217109301U) discloses an LED floodlighting fixture, which includes a fixture body. Convex card slots are symmetrically opened on the left and right sides of the fixture body. Anti-slip pads are symmetrically arranged on the left and right sides at the lower end of the fixture body. A support frame is arranged on the side of the fixture body. Fixed blocks are symmetrically welded at the upper ends of the support frame. Circular grooves are opened on the sides of the fixed blocks. When adjusting the irradiation angle of the fixture, first screw out the locking bolt along the threaded hole. The locking bolt drives the annular bevel gear block to slide along the circular groove through the slider, so that the annular bevel gear block is separated from the circular bevel gear block. At this time, the irradiation angle of the fixture can be conveniently adjusted. After the adjustment is completed, screw the locking bolt into the threaded hole. The locking bolt pushes the annular bevel gear block to move through the slider, so that the annular bevel gear block is clamped with the circular bevel gear block, thereby fixing the fixture body. The locking spring is provided to prevent the annular bevel gear block from loosening.
[0004] Although the above prior art can already achieve stable adjustment of the irradiation angle, when applying the LED floodlighting fixture in a high-temperature outdoor environment in summer, significant challenges are faced. Given that the LED floodlighting fixture needs to be exposed to the outdoors for a long time, the housing design usually has excellent sealing performance to prevent rainwater penetration. However, this sealing design often leads to serious heat accumulation problems inside the fixture, which greatly affects the service life of the device. In addition, in the actual application of the LED floodlighting fixture, the irradiation angle often needs to be continuously adjusted according to requirements. The traditional method relies on a swinging device to continuously adjust the angle. This method not only reduces the flexibility of use but also increases the operation cost and complexity.

Specifically, as the core component of heat conduction, the heat conduction plate is designed to effectively isolate the heat generated by the light source and conduct it to the heat conduction component. Subsequently, the heat dissipation fan uses the air-cooling principle to efficiently dissipate heat from the heat conduction component. This process significantly reduces the temperature level inside the lamp, thus effectively addressing the problem of heat accumulation inside the lamp in the outdoor high-temperature environment. In addition, the interior of the heat dissipation housing is cleverly divided into two independent areas, namely a sealed chamber and a heat dissipation chamber.

[0034] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners.
[0035] See Figures 1 to 14As shown, an LED floodlighting lamp comprises a heat dissipation mounting seat for stably mounting a light source 1, the heat dissipation mounting seat comprises a heat dissipation shell 2, a heat conducting component 3, a heat dissipation fan 4, a linkage swing component 5 and an adjustment mounting seat 6; a sealed chamber and a heat dissipation chamber are arranged inside the heat dissipation shell 2, a heat conducting plate 21 is arranged between the sealed chamber and the heat dissipation chamber, a docking slot is arranged on the heat conducting plate 21, and a disassembly and installation port is arranged on the side of the heat dissipation chamber; the heat conducting component 3 is installed on the disassembly and installation port, and the heat conducting component 3 is tightly fitted with the heat conducting plate 21; the heat dissipation fan 4 is installed inside the heat dissipation chamber, and the air supply end of the heat dissipation fan 4 is arranged inside the heat dissipation component 3; the adjustment mounting seat 6 is installed on the heat dissipation shell 2, and the adjustment mounting seat 6 is rotatably connected to the heat dissipation shell 2; the linkage swing component 5 is installed in the heat dissipation chamber, one end of the linkage swing component 5 is transmission-connected to the heat dissipation fan 4, and the end of the linkage swing component 5 away from the heat dissipation fan 4 is connected to the adjustment mounting seat 6.
[0036] The light source 1 is installed inside the heat dissipation housing 2, and the heat generated by the light source 1 is conducted to the heat conducting plate 21 by direct contact. The heat conducting plate 21 is located between the sealed chamber and the heat dissipation chamber, ensuring effective isolation and conduction of heat. The heat conducting component 3 fits tightly on the heat conducting plate 21, and the docking slot on the heat conducting plate 21 facilitates the limited card installation of the heat conducting component 3. The heat conducting component 3 is easy to maintain and clean by disassembling the installation port, ensuring good thermal conductivity. The heat conducting component 3 absorbs the heat energy on the heat conducting plate 21.
[0037] The heat dissipation fan 4 is installed in the heat dissipation chamber, and the air supply end of the heat dissipation fan 4 is arranged inside the heat conduction component 3. When the heat dissipation fan 4 is working, it guides the airflow to quickly pass through the heat conduction component 3, and uses the air cooling principle to efficiently dissipate the heat of the heat conduction component 3. This air cooling heat dissipation mechanism effectively reduces the temperature inside the lamp and prolongs the service life of the light source 1.
[0038] The adjustment mounting seat 6 is mounted on the heat dissipation housing 2, and the two are connected by rotation to achieve angle adjustment. One end of the linkage swing component 5 is transmission-connected to the heat dissipation fan 4, and the other end of the linkage swing component 5 is connected to the adjustment mounting seat 6. When the heat dissipation fan 4 is working, the linkage swing component 5 can convert the rotational force of the fan into a swinging force of the heat dissipation housing 2 on the adjustment mounting seat 6. The user can realize the cyclic swing of the irradiation position of the light source 1 by switching the working state of the linkage swing component 5, thereby improving the flexibility and adaptability of use.
[0039] When the light source 1 is working, heat is generated, and the heat is transferred to the heat conducting component 3 through the heat conducting plate 21. The heat dissipation fan 4 is started to guide the airflow to quickly pass through the heat conducting component 3 for air cooling and heat dissipation. When the irradiation angle of the light source 1 needs to be adjusted, the user switches the working state of the linkage swing component 5 to make the heat dissipation housing 2 swing on the adjustment mounting seat 6 to achieve the purpose of adjusting the irradiation angle.
[0040] Through innovative heat dissipation design and a flexible irradiation angle adjustment mechanism, the problems of heat accumulation inside the lamp and irradiation angle adjustment under high-temperature outdoor environments are effectively solved, improving the service efficiency and lifespan of the lamp.
[0041] The heat dissipation fan 4 is a prior art, and its working principle will not be elaborated here.
[0042] See Figure 3 and Figure 4 As shown in the figure, the heat conduction component 3 includes an adjustment bracket 31 slidably installed on the disassembly and installation opening. A circulation track 32 is installed on the adjustment bracket 31, and the circulation track 32 is attached to the heat conduction plate 21.
[0043] The heat conduction component 3 is mainly composed of an adjustment bracket 31 slidably installed on the disassembly and installation opening. A circulation track 32 is further installed on the adjustment bracket 31. The circulation track 32 is closely attached to the heat conduction plate 21 to ensure effective heat transfer. To achieve the best heat conduction effect, a heat dissipation paste can be applied to the attachment surface between the circulation track 32 and the heat conduction plate 21. Applying the heat dissipation paste improves the uniformity of contact, thereby optimizing the heat conduction path.
[0044] The function of the adjustment bracket 31 is to precisely adjust the position of the circulation track 32 so that the circulation track 32 can be closely and evenly attached to the heat conduction plate 21. Through the pushing action of the adjustment bracket 31, the circulation track 32 is effectively pressed against the heat conduction plate 21, forming a stable heat conduction.
[0045] When the heat dissipation fan 4 starts and operates, the airflow generated at the air supply end of the heat dissipation fan 4 is guided through the circulation track 32. The circulation track 32 can effectively cooperate with the airflow of the heat dissipation fan 4 to achieve uniform diversion of the cooling airflow. When the cooling airflow flows through the circulation track 32, it will carry away the heat conducted from the heat conduction plate 21 to the circulation track 32, thereby achieving efficient heat dissipation processing.
[0046] See Figures 4 to 6 As shown in the figure, the adjustment bracket 31 is provided with an air inlet hole 3111 and an air outlet hole 3112. The air inlet hole 3111 and the air outlet hole 3112 are used to connect the circulation track 32. Dust-proof nets are provided on both the air inlet hole 3111 and the air outlet hole 3112. The adjustment bracket 31 is also provided with a sliding installation groove, and a pushing connection mechanism is installed in the sliding installation groove. The pushing connection mechanism includes a movable adjustment block 313 slidably installed on the sliding installation groove. The top of the movable adjustment block 313 is provided with an anti-slip surface, the bottom of the movable adjustment block 313 is provided with a connection block 314, and a pushing spring 312 is installed between the movable adjustment block 313 and the sliding installation groove.
[0047] The adjusting bracket 31 is used to ensure the close fit between the circulation rail 32 and the heat conducting plate 21 to achieve effective heat transfer, and the adjusting bracket 31 is slidably mounted on the disassembly and installation opening of the heat dissipation housing 2. The adjusting bracket 31 is provided with a sliding installation groove for installing a push connection mechanism.
[0048] The movable adjustment block 313 is slidably installed in the sliding installation groove, and a connecting block 314 is provided at the bottom of the movable adjustment block 313 for fixing and installing the circulation rail 32. The push spring 312 is installed between the movable adjustment block 313 and the sliding installation groove, and always applies a push force to the movable adjustment block 313. Under the action of the push spring 312, the movable adjustment block 313 transfers the push force to the circulation rail 32, so that a stable and tight fit is formed between the circulation rail 32 and the heat conducting plate 21. The tight fit ensures that the heat is effectively transferred from the heat conducting plate 21 to the circulation rail 32, and then the heat is dissipated through the air cooling mechanism.
[0049] The top of the movable adjustment block 313 is provided with an anti-slip surface, which is convenient for the user to adjust the position of the movable adjustment block 313 when necessary. When the circulation rail 32 needs to be disassembled or maintained, the user can adjust the position of the movable adjustment block 313 to drive the circulation rail 32 to adjust its position synchronously, thereby facilitating disassembly and maintenance work. The adjustment bracket 31 is provided with an air inlet 3111 and an air outlet 3112, which are used to connect the circulation rail 32 to realize the circulation of airflow. The air inlet 3111 guides the cooling gas into the circulation rail 32, while the air outlet 3112 provides an effective outlet path. When the cooling gas flows through the circulation rail 32, it will take away the heat conducted to the circulation rail 32 by the heat conduction plate 21, thereby realizing efficient heat dissipation. The dustproof net is used to prevent dust from directly entering the air inlet 3111 and the air outlet 3112.
[0050] See also Figures 4 to 8 As shown, the circulating flow rail 32 is composed of a fitted heat dissipation rail 321 and a guide heat dissipation rail 322, the fitted heat dissipation rail 321 and the guide heat dissipation rail 322 are detachably connected, the fitted heat dissipation rail 321 and the guide heat dissipation rail 322 are interconnected, the fitted heat dissipation rail 321 is connected to the air outlet 3112, and the guide heat dissipation rail 322 is connected to the air inlet 3111.
[0051] The circulation rail 32 is composed of a fitting heat dissipation rail 321 and a guide heat dissipation rail 322. The fitting heat dissipation rail 321 and the guide heat dissipation rail 322 are detachably connected to facilitate later maintenance and cleaning of the internal space to ensure the heat dissipation effect. The fitting heat dissipation rail 321 is used to fit the heat conducting plate 21 tightly, thereby ensuring that heat is stably and efficiently transferred from the heat conducting plate 21 to the circulation rail 32. The guide heat dissipation rail 322 is connected to the air inlet 3111 to guide the cooling gas into the circulation rail 32.
[0052] When the cooling fan 4 starts, the airflow generated at the air supply end of the cooling fan 4 is guided through the diversion cooling rail 322. Since the diversion cooling rail 322 is sleeved on the air supply end of the cooling fan 4, the airflow can smoothly enter the interior of the diversion cooling rail 322. As the airflow flows, the airflow enters through the air inlet hole 3111 and undergoes preliminary heat dissipation inside the diversion cooling rail 322, taking away part of the heat.
[0053] Subsequently, the cooling airflow flows from the diversion cooling rail 322 into the fitting cooling rail 321. The fitting cooling rail 321 is connected to the air outlet hole 3112. During the process of the cooling airflow passing through the fitting cooling rail 321, it further contacts the fitting cooling rail 321, thereby taking away the heat conducted from the heat conduction plate 21 to the fitting cooling rail 321. In this process, the tight fit between the fitting cooling rail 321 and the heat conduction plate 21 ensures efficient heat transfer.
[0054] Finally, the cooling airflow carries a large amount of heat energy through the fitting cooling rail 321 and is discharged from the air outlet hole 3112. The entire circulation flow rail 32 realizes the effective transfer and dissipation of heat by guiding the airflow to circulate in the diversion cooling rail 322 and the fitting cooling rail 321. This design not only improves the heat dissipation efficiency but also ensures the stable control of the temperature inside the lamp, thereby extending the service life of the light source 1 and improving the overall performance of the lamp.
[0055] See Figures 4 to 8 As shown, one side of the fitting cooling rail 321 is provided with a limit locking tooth 3211, the interior of the fitting cooling rail 321 is provided with a heat dissipation channel 3212, the heat dissipation channel 3212 is communicated with the air outlet hole 3112, a plurality of heat dissipation fins 3214 are arranged on the heat dissipation channel 3212, a conical diversion block 3213 is also arranged on the heat dissipation channel 3212, and a sliding rail 3215 is also arranged on the fitting cooling rail 321.
[0056] The fitting cooling rail 321 is in close contact with the heat conduction plate 21, thereby realizing efficient heat transfer. A limit locking tooth 3211 is arranged on one side of the fitting cooling rail 321. This design ensures that during the installation process, the fitting cooling rail 321 can be stably and accurately snapped into the docking slot on the heat conduction plate 21. This snapping method not only simplifies the installation process but also ensures the tight fit between the fitting cooling rail 321 and the heat conduction plate 21, providing a basis for effective heat transfer.
[0057] Inside the fitting heat dissipation rail 321, there is a heat dissipation channel 3212, which is connected to the air outlet hole 3112, forming the main flow path of the heat dissipation air flow. A plurality of heat dissipation fins 3214 are arranged on the heat dissipation channel 3212. These heat dissipation fins 3214 increase the heat dissipation area, thereby improving the heat dissipation efficiency. When the heat dissipation fan 4 is started, when the air flow is guided into the heat dissipation channel 3212, the air flow will contact the conical guide block 3213, and the air flow will be evenly diffused under the action of the conical guide block 3213. The design of the conical guide block 3213 optimizes the flow state of the air flow, ensuring that the air flow can evenly blow towards a plurality of heat dissipation fins 3214.
[0058] During the process of the air flow passing through the heat dissipation fins 3214, heat exchange occurs between the air flow and the heat dissipation fins 3214, taking away the heat conducted from the heat conduction plate 21 to the fitting heat dissipation rail 321. The heat dissipation fins 3214 increase the contact area between the air flow and the fitting heat dissipation rail 321, further improving the heat dissipation effect. Finally, the heat dissipation air flow carries a large amount of heat energy through the heat dissipation channel 3212 and is discharged from the air outlet hole 3112, completing the process of heat transfer and dissipation. In addition, the fitting heat dissipation rail 321 is also provided with a sliding rail 3215, which facilitates the detachable connection between the fitting heat dissipation rail 321 and the diversion heat dissipation rail 322, providing convenience for later maintenance and cleaning. Through the sliding rail 3215, the fitting heat dissipation rail 321 and the diversion heat dissipation rail 322 can be firmly connected together, and at the same time can be easily disassembled, ensuring the flexibility and maintainability of the entire circulation rail 32 system.
[0059] See Figures 4 to 9 As shown, the diversion heat dissipation rail 322 is provided with a sliding slot 3221, the inside of the diversion heat dissipation rail 322 is provided with an air inlet channel 3222, the air inlet channel 3222 is connected to the air inlet hole 3111, the side of the diversion heat dissipation rail 322 is provided with an avoidance opening 3223, and the diversion heat dissipation rail 322 further includes a plugging block 3224 installed inside the heat dissipation chamber.
[0060] The diversion heat dissipation rail 322 is provided with a sliding slot 3221, and the sliding slot 3221 cooperates with the sliding rail 3215 on the fitting heat dissipation rail 321 to realize the detachable connection between the two. This connection method not only ensures the firm connection between the diversion heat dissipation rail 322 and the fitting heat dissipation rail 321, but also facilitates later maintenance and cleaning.
[0061] The inside of the diversion heat dissipation rail 322 is provided with an air inlet channel 3222, and the air inlet channel 3222 is directly connected to the air inlet hole 3111, forming the main path for the cooling gas to enter the circulation rail 32. On the side of the diversion heat dissipation rail 322, there is an avoidance opening 3223, which facilitates the air supply fan on the heat dissipation fan 4 to smoothly enter the air inlet channel 3222, thereby guiding the air flow to enter.
[0062] To ensure the correct air flow path in the air flow channel, the guiding heat dissipation rail 322 further includes a blocking block 3224 installed inside the heat dissipation chamber. The blocking block 3224 is used to dock with the avoidance port 3223 for effective blocking to prevent air flow from leaking through non-designed paths, ensuring that all air flows enter the intake air channel 3222 through the intake holes 3111.
[0063] When the heat dissipation fan 4 starts, the air supply fan begins to rotate, generating a negative pressure effect, which causes a negative pressure area to form in the intake air channel 3222. This negative pressure effect prompts external air to be sucked in through the intake holes 3111 and enter the intake air channel 3222. As the air flow moves, the cooling gas undergoes preliminary heat dissipation inside the guiding heat dissipation rail 322, taking away part of the heat.
[0064] Subsequently, the cooling gas flows from the guiding heat dissipation rail 322 into the fitting heat dissipation rail 321, and continues to exchange heat with the heat dissipation fins 3214 in the fitting heat dissipation rail 321, further taking away heat. Finally, the heat dissipation air flow carries a large amount of thermal energy through the fitting heat dissipation rail 321 and is discharged from the air outlet holes 3112, completing the process of heat transfer and dissipation.
[0065] See Figure 3 、 Figure 9 and Figure 10 As shown in, the linkage swing assembly 5 includes a gear transmission assembly 51 installed on the heat dissipation fan 4. The linkage swing assembly 5 further includes a swing linkage frame 52 installed on the gear transmission assembly 51. One end of the swing linkage frame 52 away from the gear transmission assembly 51 is fixedly connected to the adjustment mounting seat 6.
[0066] The linkage swing assembly 5 includes a gear transmission assembly 51 directly connected to the heat dissipation fan 4, and a swing linkage frame 52 driven by the gear transmission assembly 51. The gear transmission assembly 51 is designed to receive and convert the rotational kinetic energy of the heat dissipation fan 4.
[0067] During the operation of the lamp, when the heat dissipation fan 4 starts and generates a rotational motion, the rotational kinetic energy is transmitted to the gear transmission assembly 51 through a mechanical connection. Inside the gear transmission assembly 51, through precise gear meshing, this rotational kinetic energy is effectively converted and transmitted. Subsequently, the converted rotational kinetic energy further drives the swing linkage frame 52 to move. One end of the swing linkage frame 52 is tightly connected to the gear transmission assembly 51, and the other end of the swing linkage frame 52 is fixedly connected to the adjustment mounting seat 6. Therefore, when the swing linkage frame 52 is driven and swings, this swinging motion will directly act on the adjustment mounting seat 6, thereby driving the entire heat dissipation housing 2 to perform a cyclic swing on the adjustment mounting seat 6.
[0068] When it is necessary to stop the swinging action of the light source 1, the working state of the gear transmission assembly 51 can be adjusted, and the rotational kinetic energy of the gear transmission assembly 51 is disconnected from the transmission connection with the cooling fan 4. Once the gear transmission assembly 51 stops transmitting, the swing linkage 52 will no longer be driven, thereby achieving a rapid and precise stop of the swinging action of the light source 1.
[0069] See Figures 9 to 12 As shown, the gear transmission assembly 51 includes a worm 511 installed on the cooling fan 4. A turbine 512 is installed beside the worm 511. The turbine 512 is rotatably connected to the heat dissipation housing 2. The turbine 512 meshes with the worm 511. A transmission shaft 513 is installed on the turbine 512. A first transmission gear 514 is installed at one end of the transmission shaft 513 away from the turbine 512. A second transmission gear 515 is installed beside the first transmission gear 514. The second transmission gear 515 is rotatably connected to the transmission end of the swing linkage 52. A plurality of transmission slots 5151 are provided inside the second transmission gear 515. The gear transmission assembly 51 further includes a limit transmission rod 516 installed on the swing linkage 52. The limit transmission rod 516 is slidably connected to the swing linkage 52 in a limiting manner. A plurality of clamping balls 5161 are provided on the outer side of the limit transmission rod 516. A pull-adjusting rod 517 is installed at one end of the limit transmission rod 516 away from the swing linkage 52. One end of the pull-adjusting rod 517 away from the limit transmission rod 516 extends outward through the heat dissipation housing 2.
[0070] The cooling fan 4 starts and generates a rotational action during the operation of the lamp. This rotational action directly drives the worm 511 installed on the cooling fan 4 to rotate. The rotation of the worm 511 further drives the meshing turbine 512 to rotate. A rotational connection is achieved between the turbine 512 and the heat dissipation housing 2, ensuring that the turbine 512 can rotate freely without interfering with the heat dissipation housing 2. The rotation of the turbine 512 is transmitted to the first transmission gear 514 through the transmission shaft 513, causing the first transmission gear 514 to start rotating. The first transmission gear 514 serves as an intermediate link in the transmission chain, playing a connecting role. The rotation of the first transmission gear 514 drives the second transmission gear 515 beside it to rotate on the swing linkage 52. At this time, no direct driving relationship has been established between the second transmission gear 515 and the swing linkage 52.
[0071] When it is necessary to drive the swing linkage 52 to swing, the operator presses and pulls the adjustment lever 517 to push the limit drive rod 516 to move synchronously. The clamping ball 5161 on the limit drive rod 516 moves accordingly and is clamped into the drive slot 5151 of the second drive gear 515. The design of the clamping ball 5161 reduces the friction during the clamping process and ensures the smoothness of the transmission. Once the clamping ball 5161 is successfully clamped into the drive slot 5151, the rotation of the second drive gear 515 will drive the limit drive rod 516 to rotate. Since the limit drive rod 516 and the swing linkage 52 are connected with limit sliding, the rotation of the limit drive rod 516 will be directly converted into the swing power of the swing linkage 52. One end of the swing linkage 52 is subjected to the rotational action, and the rotational force is converted into a cyclic swing force, thereby driving the entire heat dissipation housing 2 to perform a cyclic swing on the adjustment mounting base 6.
[0072] When it is necessary to stop the swing of the swing linkage 52, the operator pulls the adjustment lever 517 outwards, so that the clamping ball 5161 on the limit drive rod 516 disengages from the drive slot 5151. At this time, the limit drive rod 516 stops transmitting power to the swing linkage 52, thus achieving a quick and precise stop of the swinging action of the swing linkage 52.
[0073] See Figure 3 and Figure 10 As shown in
[0074] The limit sliding groove 524 on the rotating connecting rod 523 is used for limit cooperation with the limit drive rod 516.
[0075] In the initial state, each part of the swing linkage 52 is in a relatively static position. The fixed connecting rod 521 is firmly connected to the adjustment mounting base 6, providing stable support for the entire swing linkage 52. The drive rod 522 and the rotating connecting rod 523 are respectively connected to the fixed connecting rod 521 and the heat dissipation housing 2 through rotational connections, forming a swingable mechanical structure.
[0076] When the cooling fan 4 starts and drives the gear transmission assembly 51 to rotate, the limiting transmission rod 516 in the gear transmission assembly 51 starts to rotate under the cooperation of the clamping ball 5161 and the transmission slot 5151 of the second transmission gear 515. At this time, one end of the limiting transmission rod 516 is slidably installed in the limiting chute 524 of the rotating connecting rod 523. Therefore, the rotation of the limiting transmission rod 516 will directly drive the rotating connecting rod 523 to rotate synchronously.
[0077] As the rotating connecting rod 523 rotates, the part where the distal end of the rotating connecting rod 523 is connected to the fixed connecting rod 521 through the transmission pull rod 522 will generate relative movement. Since the fixed connecting rod 521 is firmly fixed on the adjusting mounting seat 6 and cannot displace, the movement of the transmission pull rod 522 will be restricted and converted into a pulling force or a pushing force on the heat dissipation housing 2. The action of this pulling force or pushing force causes the heat dissipation housing 2 to swing on the adjusting mounting seat 6.
[0078] When it is necessary to stop the swinging action, the operator pulls the adjusting rod 517 to disengage the clamping ball 5161 on the limiting transmission rod 516 from the transmission slot 5151 of the second transmission gear 515, thereby cutting off the transmission connection between the gear transmission assembly 51 and the swinging linkage 52. At this time, the swinging linkage 52 will lose the driving force, and the swinging action of the heat dissipation housing 2 will gradually weaken and stop.
[0079] See Figure 13 and Figure 14 As shown, a plurality of limiting card holes 61 are provided on the adjusting mounting seat 6. An adjusting mounting block 62 is also rotatably installed on the adjusting mounting seat 6. The adjusting mounting block 62 is fixedly connected to the fixed connecting rod 521. A limiting chuck 64 is slidably installed on the adjusting mounting block 62. A plurality of clamping posts 65 are provided on the limiting chuck 64. A magnetic attraction block 63 is installed between the limiting chuck 64 and the adjusting mounting block 62.
[0080] A plurality of limiting card holes 61 are provided on the adjusting mounting seat 6. The limiting card holes 61 are used to cooperate with the limiting chuck 64 on the adjusting mounting block 62 to ensure the precise positioning of the adjusting mounting block 62 on the adjusting mounting seat 6.
[0081] The adjusting mounting block 62 is fixedly connected to the fixed connecting rod 521, and the fixed connecting rod 521 is an important part of the swinging linkage 52. Therefore, by adjusting the position of the adjusting mounting block 62 on the adjusting mounting seat 6, the overall angle of the heat dissipation housing 2 can be indirectly changed. To achieve this function, a limiting chuck 64 is slidably installed on the adjusting mounting block 62. A plurality of clamping posts 65 are provided on the limiting chuck 64. The clamping posts 65 are matched with the limiting card holes 61 on the adjusting mounting seat 6.
[0082] In the initial state, the clamping column 65 on the limit clamping disc 64 is clamped in the limit clamping hole 61 of the adjustment mounting seat 6, so that the installation adjustment block 62 is firmly positioned on the adjustment mounting seat 6. When the angle of the heat dissipation housing 2 needs to be adjusted, the user can pull the limit clamping disc 64 outward to disengage the clamping column 65 from the limit clamping hole 61, and then the installation adjustment block 62 and the heat dissipation housing 2 can be freely rotated on the adjustment mounting seat 6 to achieve the desired angle adjustment.
[0083] After the angle adjustment is completed, the user needs to reset the limit chuck 64 so that the clamping column 65 is re-clamped in the corresponding limit clamping hole 61. To ensure the stability of the reset of the limit chuck 64, a magnetic block 63 is installed between the limit chuck 64 and the installation adjustment block 62. The magnetic force generated by the magnetic block 63 helps to maintain the stability of the limit chuck 64 in the reset state and prevent accidental loosening or detachment due to vibration or other external factors.
[0084] Specific working principle: The light source 1 is installed inside the heat dissipation housing 2, and the heat generated by the light source 1 is conducted to the heat conducting plate 21 by direct contact. The heat conducting plate 21 is located between the sealed chamber and the heat dissipation chamber, ensuring effective isolation and conduction of heat. The heat conducting component 3 fits tightly on the heat conducting plate 21, and the docking slot on the heat conducting plate 21 facilitates the limited card installation of the heat conducting component 3. The heat conducting component 3 is easy to maintain and clean by disassembling the installation port, ensuring good thermal conductivity. The heat conducting component 3 absorbs the heat energy on the heat conducting plate 21.
[0085] The heat dissipation fan 4 is installed in the heat dissipation chamber, and the air supply end of the heat dissipation fan 4 is arranged inside the heat conduction component 3. When the heat dissipation fan 4 is working, it guides the airflow to quickly pass through the heat conduction component 3, and uses the air cooling principle to efficiently dissipate the heat of the heat conduction component 3. This air cooling heat dissipation mechanism effectively reduces the temperature inside the lamp and prolongs the service life of the light source 1.
[0086] The adjustment mounting seat 6 is mounted on the heat dissipation housing 2, and the two are connected by rotation to achieve angle adjustment. One end of the linkage swing component 5 is transmission-connected to the heat dissipation fan 4, and the other end of the linkage swing component 5 is connected to the adjustment mounting seat 6. When the heat dissipation fan 4 is working, the linkage swing component 5 can convert the rotational force of the fan into a swinging force of the heat dissipation housing 2 on the adjustment mounting seat 6. The user can realize the cyclic swing of the irradiation position of the light source 1 by switching the working state of the linkage swing component 5, thereby improving the flexibility and adaptability of use.
[0087] When the light source 1 works, it generates heat, and the heat is conducted to the heat conduction component 3 through the heat conduction plate 21. The cooling fan 4 is started to guide the air flow to quickly pass through the heat conduction component 3 for air-cooled heat dissipation. When it is necessary to adjust the irradiation angle of the light source 1, the user switches the working state of the linkage swing component 5 to make the heat dissipation housing 2 swing on the adjustment mounting base 6 to achieve the purpose of adjusting the irradiation angle. Through the innovative heat dissipation design and flexible irradiation angle adjustment mechanism, the problems of heat accumulation inside the lamp and irradiation angle adjustment in the outdoor high-temperature environment are effectively solved, and the service efficiency and life of the lamp are improved.
