Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a lighting fixture that facilitates heat dissipation. Background Technology

[0002] Currently, lighting fixtures used in special applications such as fishing boats commonly employ LEDs as the light source due to their advantages such as high luminous efficiency, long lifespan, and good shock resistance. These lights are controlled by an electronic control box containing various electronic components. However, both LEDs and electronic components generate a significant amount of heat during operation. If this heat cannot be effectively dissipated in a timely manner, it will severely impact the stability and reliability of the lighting system. Existing technologies dissipate heat by mounting the light source on a metal substrate with heat sink fins, but this is insufficient for effectively cooling the electronic control box and its internal electronic components. This leads to heat accumulation inside the control box, affecting the performance of the electronic components and consequently impacting the stability and reliability of the lighting system. Utility Model Content

To this end, the present invention proposes a lamp that facilitates heat dissipation, capable of effectively dissipating heat from both the light source and the electrical control box simultaneously.

Several heat dissipation fins on the heat dissipation area further accelerate heat dissipation. Since the heat dissipation substrate simultaneously serves as the heat dissipation path for both the lamp source assembly and the control box, it achieves a unified heat dissipation design for the main heat-generating components of the lamp (LED lamp source assembly and electronic components inside the control box), significantly improving overall heat dissipation efficiency.

[0033] Reference Figures 1 to 5 According to the present invention, a heat dissipation-friendly lamp includes a heat dissipation substrate 100, an electrical control box 200, and a lamp source assembly 300. The back of the heat dissipation substrate 100 is provided with an installation area 101 and a heat dissipation area 102. The installation area 101 is located within the heat dissipation area 102. The installation area 101 is provided with a wire through hole 103 that passes through the heat dissipation substrate 100 for passing a conductive wire. The heat dissipation area 102 is provided with a plurality of heat dissipation fins. The electrical control box 200 is fixedly installed in the installation area 101. The lamp source assembly 300 is fixedly installed on the front side of the heat dissipation substrate 100. The electrical control box 200 is electrically connected to the lamp source assembly 300 through a conductive wire.

[0034] It is understood that the heat dissipation-friendly lamp provided in this embodiment of the present invention directly fixes the control box 200 to the mounting area 101 of the heat dissipation substrate 100. This allows the heat generated by the electronic components inside the control box 200 to be conducted to the control box 200, and then efficiently conducted to its heat dissipation area 102 via the heat dissipation substrate 100. The heat is then further dissipated by several heat dissipation fins disposed on the heat dissipation area 102. Since the heat dissipation substrate 100 simultaneously serves as the heat dissipation function for the lamp source assembly 300 and the heat dissipation path for the control box 200, it achieves a common substrate integrated heat dissipation design for the main heat-generating components of the lamp (LED lamp source assembly 300 and electronic components inside the control box 200), significantly improving the overall heat dissipation efficiency. Furthermore, the wire through holes 103 provided on the heat dissipation substrate 100 facilitate the laying of conductive wires, enabling electrical connection between the control box 200 and the lamp source assembly 300 without affecting the integrity of the heat dissipation structure. This embodiment of the invention effectively avoids the problem of heat accumulation inside the electrical control box 200 in the prior art, improves the working stability and service life of electronic components, and thus enhances the reliability and long-term operating performance of the entire lighting system in harsh environments such as fishing boats. At the same time, it has a compact structure, is easy to install and maintain, and has good practicality and promotional value.

[0035] Furthermore, refer to Figure 1 and Figure 2 According to some embodiments of the present invention, the heat dissipation fins include a first heat dissipation fin 110 and a second heat dissipation fin 120. The first heat dissipation fin 110 is strip-shaped and has a star-shaped cross-section, and the second heat dissipation fin 120 is sheet-shaped, but not limited to this. The first heat dissipation fin 110 and the second heat dissipation fin 120 can also be other shapes, which can be determined according to the actual situation, and will not be elaborated here.

[0036] It is understandable that a composite heat dissipation structure is formed by setting a first heat dissipation fin 110 with a star-shaped cross-section and a second heat dissipation fin 120 in the shape of a sheet. The first heat dissipation fin 110 with a star-shaped cross-section significantly increases the heat dissipation surface area per unit volume and generates a turbulence effect under the action of airflow, enhancing the convective heat transfer efficiency; while the second heat dissipation fin 120 in the shape of a sheet is easy to arrange densely, improving the overall heat dissipation density. The two structures complement each other, taking into account both heat dissipation performance and structural strength, further optimizing the heat conduction and heat radiation capabilities of the heat dissipation substrate 100, and effectively improving the heat dissipation stability of the lamp under high-load operating conditions.

[0037] Furthermore, refer to Figure 2According to some embodiments of the present invention, the mounting area 101 is located on one side of the back of the heat dissipation substrate 100. A plurality of first heat dissipation fins 110 are provided in the middle and four corners of the back of the heat dissipation substrate 100, and a plurality of second heat dissipation fins 120 are provided on the other side of the back of the heat dissipation substrate 100. However, it is not limited to this. The distribution of the first heat dissipation fins 110 and the second heat dissipation fins 120 can also be determined according to actual needs, which will not be elaborated here.

[0038] Understandably, the highly efficient star-shaped first heat dissipation fins 110 are concentrated in the center and four corners of the back of the heat dissipation substrate 100. The central area, close to the mounting position of the control box 200, can quickly dissipate the concentrated heat generated by the control box 200, while the corner areas facilitate heat diffusion to the edges, preventing localized overheating. The remaining sides are arranged with sheet-like second heat dissipation fins 120, forming a continuous heat dissipation band and improving the overall heat dissipation uniformity. This layout achieves gradient heat conduction and efficient dissipation from the center to the periphery, significantly improving the thermal management capability of the heat dissipation substrate 100 and ensuring the thermal stability of the control box 200 and the lamp source assembly 300 working together.

[0039] Furthermore, refer to Figure 1 and Figure 2 According to some embodiments of the present invention, the surface of the electrical control box 200 is provided with a plurality of third heat dissipation fins 210. The third heat dissipation fins 210 may be located at the top and / or bottom of the electrical control box 200, or at other locations, which will not be elaborated here. The shape of the third heat dissipation fins 210 can be determined according to the actual situation, and is not specifically limited here.

[0040] Understandably, adding a third heat dissipation fin 210 to the surface of the control box 200 further expands its heat dissipation area. This allows the heat generated to be dissipated not only through conduction between the bottom and the heat dissipation substrate 100, but also through convection and radiation heat exchange with the surrounding air via the surface fins, forming a dual heat dissipation mode of "bottom conduction + surface natural convection". This design effectively reduces the operating temperature of the electronic components inside the control box 200, improving its operational reliability and service life, and is especially suitable for harsh working environments such as fishing boats with high temperature, high humidity, and poor ventilation.

[0041] Furthermore, refer to Figure 1 According to some embodiments of the present invention, the electrical control box 200 is provided with a connecting part 220, and the heat dissipation substrate 100 is provided with a positioning groove (not shown in the figure) on the side of the mounting area 101, and the connecting part 220 is fixedly connected to the positioning groove.

[0042] Understandably, by providing a positioning groove on the side of the heat sink 100 and fixing it to the connection part 220 of the electrical control box 200, not only is precise positioning and stable installation of the electrical control box 200 in the installation area 101 achieved, but also good thermal contact and heat conduction path are ensured between the electrical control box 200 and the heat sink 100, reducing thermal resistance caused by installation gaps. This structure offers reliable connection and convenient assembly, which is beneficial for improving production efficiency, while also enhancing the overall structure's seismic resistance, making it suitable for special application scenarios with frequent vibrations, such as fishing boats.

[0043] It should be noted that the electrical control box 200 can be fixedly connected by means of pins, bolts, clips, etc., which can be determined according to the actual situation, and no specific limitation is made here.

[0044] Furthermore, refer to Figure 3 and Figure 4 According to some embodiments of the present invention, the heat dissipation lamp also includes a mounting bracket 400, which has openings at both ends and hollowed out around its perimeter. The heat dissipation substrate 100 is fixedly installed inside the mounting bracket 400, and the lamp source assembly 300 is located at the front opening of the mounting bracket 400.

[0045] Understandably, the mounting bracket 400 features front and rear openings and a perforated design on all four sides, significantly improving airflow within the lamp and facilitating rapid heat dissipation from the heat dissipation fins of the heat sink 100. Simultaneously, this bracket provides excellent structural support and protection for the heat sink 100 and the lamp source assembly 300, preventing damage from external impacts. The perforated structure reduces overall weight, facilitating installation and maintenance without compromising heat dissipation performance, achieving a harmonious balance between structural strength, heat dissipation efficiency, and lightweight design.

[0046] Furthermore, refer to Figure 4 and Figure 5 According to some embodiments of the present invention, the heat dissipation lamp also includes a cooling fan 500, which is fixedly installed at the rear opening of the mounting bracket 400 and is electrically connected to the electrical control box 200.

[0047] Understandably, installing a cooling fan 500 at the rear opening of the mounting bracket 400 forms an active forced air cooling system. This effectively accelerates airflow around the heat dissipation fins on the back of the heat sink 100, significantly improving convective heat transfer efficiency, especially in high-temperature or still air environments. The cooling fan 500 is directly powered and controlled by the control box 200, enabling intelligent start / stop and speed adjustment. It dynamically adjusts the airflow according to the operating temperature of the lamp, balancing energy saving and efficient heat dissipation, further ensuring the thermal stability and reliability of the lamp under long-term high-load operation.

[0048] It should be noted that the cooling fan 500 can be fixedly connected by means of pins, bolts, clips, etc., which can be determined according to the actual situation, and no specific limitation is made here.

[0049] Furthermore, refer to Figure 4 and Figure 5 According to some embodiments of the present invention, the rear end of the mounting bracket 400 is provided with a wire inlet hole 401, and a protective coil 402 is installed in the wire inlet hole 401, so as to facilitate wiring while protecting the line.

[0050] Furthermore, refer to Figure 3 and Figure 4 According to some embodiments of the present invention, the mounting bracket 400 is mounted on the rod body through a connecting mechanism. The connecting mechanism includes two clamps symmetrically arranged on one side of the mounting bracket 400. The clamps include a first clamp 410 and a second clamp 420 that can cooperate to clamp the rod body. The first clamp 410 is fixedly mounted on the mounting bracket 400. The first clamp 410 is connected to the second clamp 420 through an adjustment structure to move closer to or further away from the second clamp 420.

[0051] Understandably, by employing an adjustable clamp-type connection mechanism, the luminaire can be adapted to mounting poles of different diameters (such as lamp posts, masts, etc.), improving installation flexibility and versatility. By adjusting the relative positions of the first clamp 410 and the second clamp 420, a secure clamping mechanism is achieved, ensuring the luminaire is installed firmly and reliably, preventing loosening or detachment. Simultaneously, the beam angle of the luminaire can be adjusted by tightening or loosening the clamp, increasing its applicability. This structure is particularly suitable for applications involving high vibration and complex environments, such as fishing boats, enhancing the luminaire's environmental adaptability and ease of installation.

[0052] It should be noted that the first hoop 410 can be fixedly connected by means of pins, bolts, clips, etc., which can be determined according to the actual situation, and no specific limitation is made here.

[0053] Furthermore, refer to Figure 3 and Figure 4 According to some embodiments of the present invention, the adjustment structure includes a first adjustment hole at both ends of the first hoop 410 and a second adjustment hole at both ends of the second hoop 420, and the first adjustment hole and the second adjustment hole are connected by an adjustment bolt 430.

[0054] It is understandable that by setting corresponding first and second adjustment holes on the first hoop 410 and the second hoop 420, and connecting them with adjusting bolts 430, stepless adjustment of the clamping force and clamping diameter of the clamp is achieved. This structure is simple, reliable, and easy to operate. Users can quickly install or remove the lamp by tightening or loosening the adjusting bolts 430, while ensuring connection strength and shock resistance.

[0055] Furthermore, refer to Figure 3 and Figure 4 According to some embodiments of the present invention, the inner side of the first hoop 410 is provided with a first tooth 411 extending in the circumferential direction, and the inner side of the second hoop 420 is provided with a second tooth 421 extending in the circumferential direction.

[0056] Understandably, by providing toothed structures on the inner sides of the first clamp 410 and the second clamp 420, when the clamps tighten on the rod, the teeth can form surface contact with the rod surface, significantly increasing friction and anti-slip capability, preventing the lamp from rotating or shifting under vibration or wind load. This anti-slip design greatly improves installation reliability, and is especially suitable for use in environments with severe turbulence and shaking, such as fishing boats, effectively ensuring the long-term stable operation of the lamp and the accuracy of the lighting direction.

[0057] Furthermore, refer to Figure 5 According to some embodiments of this utility model, the lamp source assembly 300 includes a circuit board 310 fixedly mounted on a heat dissipation substrate 100, an LED module 320 disposed on the circuit board 310, a lamp cover 330 covering the circuit board 310, and a fixing ring 340 fixing the lamp cover 330 to the heat dissipation substrate 100. The circuit board 310 is electrically connected to the electrical control box 200; the lamp cover 330 may be made of explosion-proof glass to improve explosion-proof performance; the fixing ring 340 and the heat dissipation substrate 100 may be fixedly connected by means of pins, bolts, clips, or other structural methods.

[0058] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
