Description

Technical Field

[0001] This utility model belongs to the field of lighting technology, specifically relating to a modular heat dissipation and energy-saving lighting fixture for warehouses. Background Technology

[0002] With the rapid development of modern warehousing and logistics, factory workshops and large storage centers towards large-scale and long-term lighting, the frequency of use of fixed or suspended lighting fixtures is constantly increasing. As a result, the requirements for the reliability, energy efficiency and service life of lighting systems are also increasing. LED light sources have gradually become the mainstream due to their low energy consumption and long life. However, LEDs will continuously generate a lot of heat during operation. If they cannot be guided and dissipated in time, it will lead to accelerated light decay, reduced luminous efficiency and even device damage. Therefore, efficient heat dissipation structure has become a key technical direction in the design of warehouse lighting equipment. However, existing warehouse lighting fixtures generally adopt a one-way heat dissipation structure, such as simple aluminum substrate heat dissipation, straight fin heat dissipation, or basic shell heat conduction. The heat dissipation channels are thin, and the efficiency is obviously insufficient in windless environments, dust accumulation environments, or high-temperature warehouse areas. In addition, some lighting fixtures lack independent heat dissipation design for power modules such as rectifiers, resulting in excessive local temperature rise of the whole lamp, affecting power supply stability and overall lifespan. Utility Model Content

[0003] The purpose of this utility model is to provide a modular heat dissipation and energy-saving lighting fixture for warehouses, in order to solve the problems mentioned in the background art, that existing warehouse lighting fixtures mostly adopt a single heat dissipation structure, such as aluminum substrate or straight fins, which have insufficient heat dissipation paths, low efficiency in windless, high temperature or dusty environments, and most of them lack independent heat dissipation design for power modules, which can easily cause excessive local temperature rise, affecting power supply stability and lamp life.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a modular heat dissipation and energy-saving lighting fixture for warehouses, comprising a flat circular lighting cover and a circular top plate fixed to its top by multiple screws. A component cover is provided at the center of the top of the circular top plate, and a number of heat dissipation fins are provided at equal intervals on the outer wall of the top of the circular top plate, which are arranged in a circular and equidistant manner around the component cover. The inner and outer circular walls of the flat circular lighting cover and the component cover are connected to a diffusion heat dissipation device. The diffusion heat dissipation device on the flat circular lighting cover includes a thin metal heat collection ring and a metal heat conduction pipe. A number of pipe holes are opened at equal intervals in the circumference of the flat circular lighting cover, and a metal heat conduction pipe is inserted into each pipe hole. A thin metal heat collection ring is attached to the inner circular wall of the flat circular lighting cover, and the number of metal heat conduction pipes are fixedly connected to the thin metal heat collection ring by welding.

[0005] Preferably, the connection between the metal heat pipe and the pipe hole is fixed and sealed with high-temperature resistant sealant, and the end of the metal heat pipe extending outward along the axis is set as a hemisphere, and the inside of the metal heat pipe is hollow.

[0006] Preferably, the diffusion heat dissipation device further includes several conical metal diffusion covers, which are respectively fitted and fixed to the outside of several metal heat conduction pipes, and the conical metal diffusion covers are located on the outer side of the outer wall of the flat circular lighting cover, and the small openings of the several conical metal diffusion covers are all facing the center of the flat circular lighting cover.

[0007] Preferably, the diffusion heat dissipation device further includes fixing plates and integrated fixing rings. The bottom of the large opening of the several conical metal diffusion covers is provided with fixing plates, and the integrated fixing ring is fixedly connected to the bottom of the several fixing plates. The integrated fixing ring is also sleeved and fixed on the circular outer wall of the flat circular lighting cover.

[0008] Preferably, a circular integrated lamp plate is fixed to the inner wall of the top of the flat circular lighting cover by multiple screws, and multiple LED beads are equidistantly arranged at the bottom of the circular integrated lamp plate.

[0009] Preferably, the flat circular lighting cover has a sealing ring on the bottom annular inner wall and a transparent protective sheet on the top of the sealing ring. The two are sealed and fixed together by sealant, and the transparent protective sheet is located below the circular integrated light panel.

[0010] Preferably, a rectifier is fixed inside the component cover by screws, and the LED beads and the circular integrated lamp board are electrically connected to the rectifier by wires.

[0011] Preferably, the top center of the component cover is fixed with a mounting ring by a welding piece, and a power socket is provided on the right side of the top center of the component cover, and the rectifier is electrically connected to the power socket.

[0012] Compared with the prior art, this utility model provides a modular heat dissipation and energy-saving lighting fixture for warehouses, which has the following beneficial effects: This invention incorporates a diffusion-type heat dissipation device on both the flat circular lighting cover and the component cover, enabling the lamp to form a multi-path heat dissipation system composed of a thin metal heat collection ring, metal heat conduction pipes, and a conical metal diffusion cover. The thin metal heat collection ring is closely attached to the inner wall of the flat circular lighting cover, which can quickly absorb the heat generated by the circular integrated lamp board and LED beads, and promptly transport the heat to the outside of the lamp through multiple metal heat conduction pipes. The metal heat conduction pipes are hollow and have hemispherical ends, which can increase the heat exchange area and improve the heat conduction speed, ensuring efficient transfer of internal heat to the outside. Meanwhile, the outer conical metal diffuser can further expand the heat dissipation contact surface area, allowing the conducted heat to spread rapidly on its conical wall surface. This is not only suitable for natural heat dissipation in static environments, but also for guiding air to flow rapidly along the conical curved surface in scenarios with airflow, thereby enhancing convective heat dissipation efficiency and reducing heat retention. In addition, the heat dissipation structure on the flat circular lighting cover and the component cover works together to simultaneously reduce the operating temperature of the LED beads and rectifier, avoiding performance degradation caused by local heat accumulation, effectively extending the life of the lamp and improving overall energy efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figure 1-5The illustration shows a modular heat dissipation and energy-saving luminaire for warehouses. The luminaire adopts a layered assembly structure. The flat circular lighting cover 1 is located at the bottom of the luminaire and is used to house the lighting components and provide the main space for the heat dissipation system. The transparent protective sheet 8 is set on the lower inside of the flat circular lighting cover 1 and forms a continuous seal with the lighting cover through sealant to prevent dust and moisture from entering the inside of the lighting cover, thereby protecting the working environment of the circular integrated light board 9 and multiple LED beads 10. The circular integrated light board 9 is fixed to the inner surface of the flat circular lighting cover 1 by a multi-point fixing method. Multiple LED beads 10 are evenly arranged on its lower side. When the LED beads 10 are powered on, they generate high brightness light output and a large amount of heat. In order to dissipate the heat generated by the LED beads 10 as quickly as possible, a thin metal heat collection ring 11 is installed tightly inside the flat circular lighting cover 1. The thin metal heat collection ring 11 is made of a metal material with high thermal conductivity and can collect the heat from the heat source inside the lighting cover in real time when the LED beads 10 are working and transfer the heat to multiple metal heat conduction pipes 13.

[0021] like Figure 1 , Figure 4 and Figure 5 As shown, several metal heat-conducting pipes 13 are distributed along the circumference of the flat circular lighting cover 1. One end of the metal heat-conducting pipe 13 is inserted into the pipe hole on the lighting cover and welded to the thin metal heat-collecting ring 11, so that heat can be transported outward along the hollow structure of the metal heat-conducting pipe 13. A conical metal diffuser 12 is sleeved on the outside of the metal heat-conducting pipe 13. The larger opening side of the conical metal diffuser 12 faces the outside air, and the smaller opening is aligned with the center of the flat circular lighting cover 1. The heat conduction area is expanded through its conical curved surface, and a smooth airflow channel is formed around the lamp. Fixing plates 14 are set at the bottom of several conical metal diffusers 12. The fixing plates 14 are then limited by an integrated fixing ring 15, so that the entire diffused heat dissipation device 3 is stably surrounded around the lighting cover, forming a continuous heat dissipation outer ring structure, thereby constituting a complete diffused heat dissipation device 3.

[0022] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a circular top plate 2 is installed above the flat circular lighting cover 1. The circular top plate 2 is locked to the lighting cover with screws, so that the lamp forms a stable shell structure. Several heat dissipation fins 4 are arranged in groups on the outer surface of the circular top plate 2. The heat dissipation fins 4 are arranged at equal intervals along the circumference, which can enhance the air convection capability of the lamp in natural wind environment and further improve heat dissipation efficiency. The component cover 5 is installed in the central part of the circular top plate 2. The rectifier is fastened to the inside of the component cover 5 with screws. The rectifier is responsible for converting the AC power input from the outside through the power socket 7 into DC power suitable for the operation of LED beads 10. At the same time, it stabilizes the output voltage to prevent the LED beads 10 from being damaged due to voltage fluctuations. The rectifier generates heat in the process of converting AC to DC. The heat is quickly dissipated to the outside through the diffusion heat dissipation device 3 outside the component cover 5 and exchanged with the surrounding air, thereby keeping the rectifier within a stable temperature rise range.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a hanging ring 6 is welded to the top of the component cover 5 to facilitate vertical hanging of the lamp in the storage environment. The power socket 7 is located on the side of the component cover 5 for connecting an external power supply cable to realize the electrical power supply of the rectifier and the LED lighting system. When the lamp is powered on, the LED beads 10 work to generate light and heat. The heat is quickly transferred to the thin metal heat collection ring 11 through the circular integrated lamp plate 9, and then discharged outward through the metal heat conduction pipe 13. It is diffused through the conical surface of the conical metal diffuser cover 12 and fully convects with the air. At the same time, the heat generated by the rectifier when completing the AC to DC power conversion is dissipated outward synchronously through the component cover 5 and the heat sink fins 4, so that the whole lamp maintains a stable operating temperature rise and improves the reliability of long-term lighting in the storage environment.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
