Description
Technical Field
[0001] This utility model relates to the field of dock light heat dissipation technology, specifically a dock light with built-in exhaust fan heat dissipation. Background Technology
[0002] As a core safety feature for nighttime operations in ports and dock areas, the selection of dock lights requires precise matching based on specific application scenarios, such as explosion-proof rating, rated power, and illumination coverage. Ports and docks serve as logistics hubs operating around the clock, and nighttime lighting must withstand harsh conditions including high salt spray and dust. Therefore, lighting fixtures must not only meet the demands for high-intensity illumination but also possess stability suitable for such harsh environments.
[0003] However, dockside lighting typically has a high luminous power to ensure sufficient illumination in the work area, resulting in significant heat generation, which is mostly concentrated in areas with densely packed internal components. The core components, such as internal LED chips and driver modules, release a large amount of heat when emitting light at high intensity. The compact installation layout further reduces the heat exchange space, preventing heat from dissipating quickly through natural convection. This easily leads to localized high-temperature accumulation, potentially causing component burnout, performance degradation, and a significantly shortened lifespan, directly threatening the continuity and safety of critical operations such as nighttime loading and unloading and shipping scheduling.
[0004] To address this, we propose a dock light with built-in exhaust fan for heat dissipation. Utility Model Content
[0005] The purpose of this utility model is to provide a dock light with built-in exhaust fan for heat dissipation, which solves the problem of poor heat dissipation efficiency of existing dock lights by using heat dissipation components and auxiliary components in combination.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A dock light with built-in exhaust fan heat dissipation includes a lamp housing, an internal component inside the lamp housing, and a lamp cover installed outside the internal component. It also includes: an air inlet located on the top of the lamp housing, an air outlet located diagonally opposite the air inlet, dust filters installed inside both the air inlet and the air outlet, and a cooling fan installed inside the air inlet; a heat dissipation component installed inside the lamp housing for dissipating heat from the internal component; and an auxiliary component installed within the heat dissipation component for assisting in heat dissipation.
[0007] Preferably, the heat dissipation component includes a mounting plate installed inside the lamp housing, and an outer shell is snapped onto the outside of the mounting plate, with through holes evenly distributed on the outer shell.
[0008] Preferably, the mounting plate has multiple heat-conducting plates installed inside, and cooling fans are installed outside the multiple heat-conducting plates. Heat sinks are installed outside the cooling fans, and the heat-conducting plates are annular.
[0009] Preferably, the auxiliary component includes a motor mounted on a mounting plate, the output end of the motor being fixedly connected to a lead screw via a coupling, and a slider being connected to the external thread of the lead screw.
[0010] Preferably, a limiting rod is fixedly connected to the outside of the mounting plate, a sliding block is slidably connected to the outside of the limiting rod, and a connecting frame is fixedly connected to the outside of both the mounting plate and the sliding block.
[0011] Preferably, an annular frame can be detachably installed between the two connecting frames, and a fiber brush cloth is fixedly connected to the outside of the annular frame.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model device is equipped with a highly efficient heat dissipation component. By installing a cooling fan at the air inlet, external cool air can be easily introduced into the lamp housing.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings.
[0016] The following description is intended to disclose the present invention and to enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.
[0017] Example 1: Please refer to Figure 1 - Figure 6 The diagram illustrates a dock light with a built-in exhaust fan for heat dissipation. It includes a lamp housing 1, which serves as the main load-bearing structure. Made of high-strength engineering plastic, the housing 1 possesses excellent impact resistance and weather resistance, effectively withstanding wind, sun, and rain in the harsh port environment. Inside the housing 1 are internal components 3, and outside these components is a lampshade 2. The lampshade 2 is made of high-transmittance PC material, with a transmittance of up to 92%, effectively reducing light refraction loss and ensuring uniform and efficient scattering of light emitted from the internal components 3, forming a stable and bright lighting area to meet the lighting needs of the complex working environment at the dock. The light housing also includes an air inlet 6 located above the housing 1, and an air outlet 8 located diagonally opposite the air inlet 6. Together, the air inlet 6 and the diagonally opposite air outlet 8 form a diagonal ventilation channel. This layout design fully utilizes aerodynamic principles; when the cooling fan 9 is activated, it creates efficient air convection inside the housing 1.
[0018] Both the air inlet 6 and the air outlet 8 are equipped with dust filters 7. These filters are made of high-density woven fibers, and their unique fiber structure effectively intercepts dust particles ≥5μm, preventing external pollutants from entering the lamp body and ensuring the normal operating environment of the internal components 3, thus extending their service life. An air cooler 9 is installed inside the air outlet 8, providing ample cooling for the internal components 3 and effectively reducing their internal temperature. Additionally, a heat dissipation component 4 is installed inside the lamp housing 1 to dissipate heat from the internal components 3. Furthermore, an auxiliary component 5 is installed within the heat dissipation component 4 to assist in heat dissipation.
[0019] Specifically, the heat dissipation component 4 includes a mounting plate 10 installed inside the lamp housing 1, which is carefully crafted from 6063-T5 aluminum alloy. This material not only has the advantages of low density and light weight, but also has high strength and hardness. After anodizing, a dense oxide film is formed on its surface, which can quickly and efficiently conduct the heat generated by the internal components 3. The mounting plate 10 is externally attached to a housing 11, and the housing 11 is uniformly provided with through holes 23.
[0020] Furthermore, multiple cooling plates 12 are installed inside the mounting plate 10. These cooling plates 12 employ an advanced heat pipe structure and are filled with a special working fluid. When the internal component 3 generates heat, the heat is first transferred to the cooling plates 12. The working fluid within the cooling plates 12 evaporates upon heating, rapidly transferring the heat to the external cooling fans 13. Cooling fans 13 are installed outside the multiple cooling plates 12. These fans are driven by DC brushless motors, featuring high efficiency and low noise. Heat sinks 14 are installed outside the cooling fans 13. The heat sinks 14 are annular and employ an aluminum fin array design. The fin spacing is precisely controlled at 2mm. This tightly arranged fin structure significantly increases the heat dissipation area by 40% compared to traditional flat structures, significantly improving air convection efficiency and allowing heat to be carried away more quickly. This effectively reduces the temperature of the internal component 3, ensuring stable operation of the dock light under long-term, high-intensity working conditions.
[0021] It should be noted that by installing a cooling fan 9 at the air inlet 6, it is easy to draw external cold air into the lamp housing 1. In conjunction with the cooling fan 13, the cooling plate 12 and the heat sink 14 inside the heat dissipation component 4, air convection is easily formed inside the lamp housing 1, which in turn improves the heat dissipation effect of the dock light and thus improves the service life of the dock light. Example 2: This embodiment is a further explanation of Example 1, based on... Figure 1 - Figure 6As shown, it is worth noting that the auxiliary component 5 includes a motor 15 mounted on the mounting plate 10. A 24V permanent magnet synchronous motor is selected. This type of motor performs well in many small power drive scenarios due to its high efficiency, high power density and precise control performance. The output end of the motor 15 is fixedly connected to a lead screw 16 through a coupling. The lead screw 16 is connected to a slider 17 by external threads. The slider 17 can move along the axial direction. This precise displacement control provides a stable motion basis for subsequent cleaning operations. The slider 17 has a threaded hole inside that corresponds to the lead screw 16.
[0022] Specifically, the mounting plate 10 is externally fixedly connected to a limiting rod 19, which is made of aluminum alloy with a polished surface. Aluminum alloy not only has good lightweight properties, reducing the weight of the overall structure, but also has high strength and hardness, and can withstand a certain lateral force. A sliding block 20 is externally connected to the limiting rod 19, and the sliding block 20 has a slot corresponding to the limiting rod 19. Both the mounting plate 10 and the slider 17 are externally fixedly connected to a connecting frame 18. Through the cooperation of the limiting rod 19 and the sliding block 20, the movement direction of the slider 17 can be restricted, ensuring that the slider 17 can only move in a straight line in the horizontal direction under the drive of the lead screw 16. This effectively avoids the problem of poor cleaning effect caused by movement deviation, and ensures that the fiber brush cloth 22 can always maintain good contact with the surface of the heat sink 14, achieving efficient cleaning operation.
[0023] Furthermore, an annular frame 21 can be detachably installed between the two connecting frames 18. It can be fixed by bolts and nuts or by magnetic adsorption, which is not limited. A fiber brush cloth 22 is fixedly connected to the outside of the annular frame 21. The fiber brush cloth 22 is made of microfiber cloth, and the tiny gaps on the surface form a "wrap-like" adsorption. Dust enters the gaps and is stuck, preventing it from falling off. The surface of the fiber brush cloth 22 is also treated with special antistatic treatment, which effectively reduces the generation of static electricity and further improves the adsorption capacity for dust particles.
[0024] By starting the motor 15, the lead screw 16 is rotated, which in turn drives the slider 17 and the moving block 20 to move synchronously. This facilitates the fiber brush cloth 22 to adsorb dust on the surface of the heat sink 14. At the same time, in conjunction with the dustproof net 7, the heat dissipation effect of the heat dissipation component 4 is further improved, thereby facilitating the extension of the service life of the dock light.
[0025] The principle behind this solution is as follows: First, when the dock light is activated, the internal component 3 generates heat by emitting light, and the cooling fan 9 inside the air outlet 8 starts simultaneously. The fan blades are driven to rotate at high speed by a DC24V motor, creating a negative pressure environment inside the lamp housing 1. At this time, under the action of air pressure difference, the external cold air enters the inner cavity of the lamp housing 1 after being filtered by the dustproof net 7 of the air inlet 6. The dustproof net 7 intercepts dust particles in the air through its high-density fiber woven structure, preventing pollutants from adhering to the surface of the internal component 3 and the heat dissipation component 4.
[0026] Secondly, the cold air flows along the internal cavity of the lamp housing 1, first contacting the surface of the internal component 3 and absorbing some of the heat it emits, and then continues to move towards the heat dissipation component 4. The outer shell 11 of the mounting plate 10 provides a passage for the cold air through evenly distributed through holes 23, allowing the airflow to fully penetrate into the heat dissipation component 4. At the same time, the cooling fan 13 in the heat dissipation component 4 operates synchronously, accelerating the speed of the cold air flowing through the cold guide plate 12 and the annular heat sink 14, forming a complete airflow cycle of "intake-guidance-heat exchange-exhaust". The hot air carrying heat is finally discharged from the lamp housing 1 through the air outlet 8, completing one heat dissipation cycle. Subsequently, with the accumulation of usage time, dust easily accumulates on the surface of the annular heat sink 14, affecting heat exchange efficiency. At this time, the auxiliary component 5 initiates the cleaning process: the motor 15 starts after receiving a control signal, driving the lead screw 16 to rotate at a set speed. The lead screw 16 precisely engages with the threaded hole of the slider 17 through a trapezoidal thread, converting the rotational motion into the horizontal linear motion of the slider 17. The limit rod 19 on the mounting plate 10 restricts the movement direction of the slider 17, ensuring its stable movement in the horizontal direction and preventing deviation that could lead to incomplete cleaning.
[0027] Finally, the slider 17 and the mounting plate 10 move synchronously with the annular frame 21 via the connecting frame 18, and the fiber brush 22 on the outside of the annular frame 21 slides tightly against the surface of the annular heat sink 14. The ultra-fine fiber structure of the fiber brush 22 firmly adsorbs dust particles on the surface of the heat sink 14 and between the fins through a "wrap-up" adsorption effect, preventing dust from falling off and causing secondary pollution. During the cleaning process, the dustproof net 7 continuously intercepts new dust from entering, and the two form a dual guarantee of "internal cleaning + external protection", maintaining the long-term stable heat dissipation efficiency of the heat dissipation component 4 and indirectly extending the overall service life of the dock light.
