Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for tunnel LED lights, and in particular to a heat dissipation structure for tunnel LED lights. Background Technology

[0002] Integrated aluminum alloy heat dissipation structures are currently the most common design solution for LED tunnel lights. Their key feature is that the lamp housing and heat sink are designed as a single unit, utilizing the high thermal conductivity of aluminum alloy for efficient heat dissipation. Most use high thermal conductivity aluminum alloys such as 6063, with surfaces treated by anodizing or electrostatic spraying, ensuring both heat dissipation performance and improved corrosion resistance. The heat dissipation device is integrated with the lamp housing, typically employing a wave-shaped or finned heat sink structure to increase the heat dissipation area. However, existing junction heat dissipation structures still suffer from insufficient heat dissipation efficiency and cannot meet the heat dissipation requirements of LED lights. When an LED chip is working, only about 30% of its electrical energy is converted into light energy, while the remaining 70% is dissipated as heat. If heat dissipation is not timely and effective, the chip junction temperature will rise, leading to accelerated light decay, color temperature drift, and even device failure. Research shows that for every 10°C increase in LED junction temperature, its lifespan may decrease by more than 50%. Heat dissipation performance has become a key factor restricting the reliability and lifespan of LED tunnel lights. Therefore, better heat dissipation structures are needed to solve the heat dissipation problem of LED lights. Summary of the Invention

[0003] The purpose of this invention is to provide a heat dissipation structure for tunnel LED lights, addressing the aforementioned problems and solving the technical issue of low heat dissipation efficiency in traditional tunnel LED light heat dissipation structures.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A heat dissipation structure for a tunnel LED light includes a lamp housing, two heat sink groups, and a mounting plate. The lamp housing has openings at both ends and the top, and the bottom surface of the lamp housing forms a mounting surface. The two heat sink groups are respectively disposed on both sides inside the lamp housing. Each heat sink group includes a plurality of heat sinks, which are arranged alternately and conform to the shape of the side wall of the lamp housing. The mounting plate is provided on the upper part of the openings at both ends of the lamp housing.

[0005] Furthermore, the heat sink assembly includes a first heat sink and a second heat sink, which are arranged alternately. A first gap is provided between the first heat sink and the inner sidewall of the corresponding lamp housing, and a second gap is provided between the second heat sink and the first heat sink. A plurality of flow guides are provided alternately in the middle of both the first and second heat sinks.

[0006] Furthermore, the upper part of the second heat sink forks to form several heat sink sub-fins.

[0007] Furthermore, the heat sink assembly also includes a heat dissipation baffle, which is arranged alternately with the second heat sink.

[0008] Furthermore, the first heat sink, the second heat sink, and the heat dissipation baffle are all curved, and the upper ends of the first heat sink, the second heat sink, and the heat dissipation baffle all face the middle of the lamp housing.

[0009] Furthermore, the lamp housing and the two heat sink assemblies are integrally formed.

[0010] Furthermore, mounting strips are provided on the upper part of both sides of the lamp housing, the mounting holes extend to both ends along the length of the lamp housing, and through mounting holes are provided in the mounting strips. The mounting plate is mounted on the lamp housing through the mounting holes.

[0011] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: 1. When using this utility model, the LED module can be installed on the mounting surface of the lower end of the lamp housing, and two heat sink groups are provided. The heat sinks can increase the contact area between the structure and the air, thereby increasing the heat dissipation area. After the mounting plate is connected, cold air enters from the bottom at both ends of the lamp housing, while hot air overflows upwards, making it easier for the air to form a heat backflow. Based on the above, this utility model can solve the technical problem of low heat dissipation efficiency of traditional tunnel LED lighting structures.

[0012] 2. The first and second heat sinks of this utility model have corresponding air guide ports, which can allow the lower temperature gas located in the first gap to enter the middle through the air guide ports, making it easier to form an airflow to carry away the heat concentrated in the middle; by forming several heat dissipation sub-plates in the upper part of the second heat sink, the contact area between the second heat sink and the air can be increased, further improving the heat dissipation efficiency.

[0013] 3. This utility model adopts an integrated lamp housing and two heat sink assemblies, which can be initially processed into shape using aluminum profile processing technology. Then, according to the drawing requirements, a certain length is taken and cutting is performed. After completion, holes are made according to the corresponding size requirements. The processing is simple, convenient and low-cost. Attached Figure Description

In use, the LED module can be installed on the mounting surface 4 on the lower end face of the lamp housing 1, where two heat sink groups 2 are provided. The heat sinks can increase the contact area between the structure and the air, thereby increasing the heat dissipation area.

Specifically, the first heat sink 5, the second heat sink 6, and the heat dissipation baffle 11 have the same curvature at corresponding heights. The lamp housing 1 and the two heat sink assemblies 2 are integrally formed. Corresponding airflow guides 9 are added to the first heat sink 5 and the second heat sink 6, allowing the lower-temperature gas located in the first gap 7 to enter the center through the airflow guides 9, making it easier to form an airflow that carries away the concentrated heat in the center. For specific airflow details, please refer to [further details].
