An LED lamp

Abstract

The application relates to the technical field of LED lamps, in particular to an LED lamp which comprises a shell and an LED lamp plate arranged in the inner cavity of the shell, and a gap for air circulation is formed between the panel edge of the LED lamp plate and the inner wall of the shell. The application creates a natural air circulation channel in the lamp shell by reserving the gap between the LED lamp plate edge and the shell inner wall, allows the internally accumulated hot air to naturally convect outward through the gap, and meanwhile, the cooler air outside can also supplement into the gap, forming a passive heat dissipation air duct. This effectively alleviates the problem of internal heat accumulation caused by the closure of the shell, reduces the operating temperature of the LED lamp plate and electronic components, slows down the thermal aging, and significantly improves the service life and light efficiency stability of the lamp in an outdoor closed environment.

Description

Technical Field

[0001] This application relates to the field of LED lighting fixtures, and more particularly to an LED lamp. Background Technology

[0002] LEDs have the advantages of high luminous efficiency, energy saving and long life, and their applications are becoming increasingly widespread. When LEDs are used in daily lighting, multiple high-power LEDs are usually combined in a single lamp to achieve the required illuminance.

[0003] In related technologies, in order to ensure the waterproofness of LED lights, the housing of LED lights used in outdoor scenarios is mostly sealed, and no heat dissipation holes are opened on the housing of the LED lights. This causes the heat generated by the LED lights to accumulate inside the housing and is difficult to dissipate, which will accelerate the thermal aging of the product and affect its service life. Utility Model Content

[0004] In order to improve the lifespan of LED lights, this application provides an LED light.

[0005] This application provides an LED light, which adopts the following technical solution:

[0006] An LED lamp includes a housing and an LED light panel disposed in the inner cavity of the housing, wherein a gap for air circulation is formed between the edge of the LED light panel and the inner wall of the housing.

[0007] By adopting the above technical solution, a natural airflow channel is created inside the lamp housing through the gap reserved between the edge of the LED light panel and the inner wall of the housing. This design breaks away from the completely sealed state of traditional enclosed outdoor LED lights, allowing the accumulated hot air inside to be naturally convected and discharged outwards through the gap, while cooler external air can also be drawn in through the gap, forming a passive heat dissipation channel. This effectively alleviates the problem of internal heat accumulation caused by the sealed housing, reduces the operating temperature of the LED light panel and electronic components, thereby slowing down thermal aging and significantly improving the lifespan and luminous efficacy stability of the lamp in outdoor enclosed environments. At the same time, the gap structure is simple, does not compromise the integrity of the housing, and has minimal impact on waterproof performance.

[0008] Optionally, the inner wall of the housing is provided with a mounting member, and the end of the mounting member away from the inner wall of the housing is provided with a mounting groove for screw insertion, and the LED light board is provided with a through mounting hole for screw to pass through.

[0009] By adopting the above technical solution, and by setting mounting parts with mounting grooves on the inner wall of the housing and opening mounting holes on the LED light board, the LED light board can be directly and securely fixed to a specific position inside the housing with screws. This installation method has a clear structure, is easy to operate, and has a reliable connection, ensuring the positioning accuracy and firmness of the LED light board in the housing, effectively preventing displacement caused by vibration or its own weight, and also helping to accurately maintain the gap size for air circulation.

[0010] Optionally, the housing is formed by connecting multiple connecting segments in sequence, the cross-sectional dimensions of each connecting segment increase along the arrangement direction of each connecting segment, the mounting member is disposed on the inner wall of one of the connecting segments, and the mounting member extends along the arrangement direction of each connecting segment.

[0011] By adopting the above technical solution, the structure of the housing and the layout of the mounting components are optimized. The housing is composed of multiple connecting segments with increasing cross-sectional dimensions. The mounting components are placed on the inner wall of one of the connecting segments and extend along the direction of the connecting segments (which can be understood as the vertical direction). This allows the gap for air circulation to be formed by extending the length of the mounting components. Compared with the mounting components extending in the horizontal direction (close to the central axis of the housing), this maximizes the panel area of ​​the LED light panel, balances lighting effect and heat dissipation effect, and further improves waterproof and insect-proof effects.

[0012] Optionally, a fan may also be provided in the inner cavity of the housing.

[0013] By adopting the above technical solution and installing a fan inside the housing, airflow can be forced, significantly accelerating the discharge of hot internal air through the gaps and drawing in cool external air. This enhances the overall heat dissipation capacity of the lamp, making it particularly suitable for high-power LED panels or high-temperature operating environments. It can more effectively control the internal temperature, further extending the lifespan of LEDs and related electronic components, and improving luminous efficacy maintenance.

[0014] Optionally, the plane in which the rotation axis of the fan is located is parallel to the panel of the LED light board.

[0015] By adopting the above technical solution, the rotation axis plane of the fan is set parallel to the LED light panel, meaning that the airflow generated by the fan is mainly parallel to the surface of the LED light panel (e.g., blowing or sucking along the length of the light panel). This allows external airflow to enter the housing cavity through the gap on one side of the LED light panel, while hot airflow is distributed throughout the housing through the gap on the other side of the LED light panel. Compared to airflow perpendicular to the light panel (which may be obstructed by the structure) or arrangements with uncertain directions, the design of this application ensures that the air intake and exhaust do not interfere with each other, minimizing the formation of turbulent airflow. Furthermore, this airflow direction can more effectively sweep across the surface of the LED light panel, the main heat source, maximizing the heat exchange efficiency between the airflow and the heat source, carrying away the heat generated by the light panel, and achieving a better heat dissipation effect for the light panel.

[0016] Optionally, a bracket is provided on the surface of the LED light panel away from the LED. The bracket is made of insulating and heat-insulating material. The fan is mounted on the bracket, and a circuit board is also provided on the bracket.

[0017] By adopting the above technical solution and using a bracket made of insulating and heat-insulating material, the fan and LED light panel (which are electrified and generate heat) are physically isolated, improving electrical safety and preventing short-circuit risks. Furthermore, its heat insulation reduces heat conduction from the fan area to the circuit board or from the light panel to the fan, protecting the fan motor and sensitive components on the circuit board. Simultaneously, the bracket integrates the fan and circuit board on the back of the light panel (non-LED side), effectively utilizing the space behind the light panel and resulting in a more compact and orderly internal structure, facilitating assembly and maintenance.

[0018] Optionally, the bracket consists of multiple support legs, and each support leg is arranged around the central axis of the bracket.

[0019] By adopting the above technical solution, the bracket consists of multiple support legs arranged around the central axis, which can form a stable support.

[0020] Optionally, the support foot includes a mounting portion, the ends of the mounting portions of each support foot are connected, the mounting portion extends along the extension direction parallel to the panel of the LED light board, the surface of the mounting portion away from the LED light board is the mounting surface, and the panel of the circuit board is in contact with the mounting surface.

[0021] By adopting the above technical solution, the mounting ends of each support foot are connected and extend parallel to the surface of the lamp panel, forming a stable ring or frame-type mounting platform. The circuit board is directly mounted on the mounting surface of the mounting part, ensuring the flatness and stability of the circuit board installation. At the same time, concentrating the circuit board on the platform formed by the mounting parts facilitates the rational layout of circuit components and wiring harness management.

[0022] Optionally, there is a distance between the mounting part and the panel of the LED light board.

[0023] By adopting the above technical solution, there is a distance between the mounting part and the LED light panel, which allows air to circulate freely between the back of the LED light panel and the mounting part / circuit board, carrying away the heat generated on the back of the light panel and the heat generated by the circuit board, and preventing heat from accumulating in the narrow space; secondly, this physical isolation space further enhances the insulation safety and reduces the risk of short circuit between the circuit board and the live light panel due to contact or foreign objects.

[0024] Optionally, the support foot further includes a support part connected to the mounting part, the support part being detachably connected to the LED light board, the fan being detachably connected to the support part of any one of the support feet, and the plane where the rotation axis of the fan is located is parallel to the panel of the circuit board.

[0025] By adopting the above technical solution, the support unit connects to the mounting unit and is detachably connected to the LED light panel (e.g., with clips, screws, etc.). This allows the entire bracket (composed of support legs) to be easily installed or removed from the light panel, facilitating the assembly, maintenance, or replacement of components. Crucially, the fan is designed to be detachably connected to the support unit of any of the support legs, providing significant installation flexibility. Users can choose the most suitable location to install the fan (e.g., on the support leg corresponding to the hottest area of ​​the light panel) based on heat dissipation requirements (e.g., temperature differences between areas) or space constraints. The fan's rotation axis is parallel to the circuit board panel, preventing obstruction of the circuit board, simplifying wiring, and facilitating independent inspection of the fan or circuit board. This modular design significantly improves the product's adaptability and maintainability.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By creating a natural airflow channel inside the lamp housing through the gap between the edge of the LED light panel and the inner wall of the housing, the problem of internal heat accumulation caused by the closed housing is effectively alleviated, the operating temperature of the LED light panel and electronic components is reduced, thereby slowing down thermal aging and significantly improving the lifespan and luminous efficiency stability of the lamp in outdoor enclosed environments.

[0028] 2. Set the fan's rotation axis plane to be parallel to the LED light panel, so that the air intake and exhaust do not interfere with each other, avoid the formation of airflow turbulence as much as possible, and this airflow direction can more effectively sweep across the surface of the LED light panel, which is the main heat source, maximize the heat exchange efficiency between the airflow and the heat source, remove the heat generated by the light panel, and obtain a better heat dissipation effect for the light panel.
