Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically to a waterproof and moisture-proof LED lighting fixture encapsulation and sealing structure. Background Technology

[0002] LED lights are highly efficient and energy-saving light sources that directly convert electrical energy into light energy using solid-state semiconductors. Compared to traditional incandescent and fluorescent lamps, LED lights offer advantages such as high luminous efficiency, low energy consumption, long lifespan, fast response speed, and environmental friendliness, making them widely used in indoor and outdoor lighting, backlighting displays, and decorative lighting. In recent years, with continuous advancements in LED technology and cost reductions, the market share of LED lighting fixtures has gradually increased across various lighting markets. However, in humid or other harsh environments, their waterproof and moisture-proof performance becomes a crucial factor affecting their lifespan and performance stability.

[0003] Utility model patent CN208186077U discloses a waterproof and moisture-proof LED lamp, including a fixed base and a connecting shaft. A connecting rod is located at the bottom center of the fixed base, and a crossbar is located at the other end of the connecting rod. The connecting rod passes through the middle of the crossbar and is fixedly connected to the crossbar by a fixing bolt. A limiting groove is provided on the upper surface of the crossbar, with a connecting groove at each end of the bottom of the limiting groove. Seven limiting slots are provided on both sides of the opening at the top two ends of the limiting groove. This utility model adds an adjustable U-shaped fixing frame. Two connecting plates slide horizontally left and right at both ends of the crossbar, adjusting the distance between the two connecting plates. Then, hook plates are engaged into the limiting slots to fix the position of the connecting plates. Compared with the traditional fixed U-shaped fixing frame, the fixing frame composed of the crossbar and connecting plates allows for flexible adjustment, is suitable for LED lamp bodies of different sizes, and is more convenient to use.

[0004] The aforementioned existing technologies use a sealed glass cover on the outside of the LED bulb to prevent moisture from affecting the LED lamp body, thus achieving waterproof and moisture-proof effects. However, while this completely sealed design prevents external moisture from entering, it also prevents the heat generated by the LED lamp during operation from being effectively dissipated, further affecting the lamp's lifespan. Simultaneously, during the encapsulation process, a small amount of moisture may remain inside the lamp before sealing. This moisture is difficult to remove in a sealed environment, easily leading to condensation inside the lamp, causing circuit corrosion or short circuits, severely impacting the lamp's stability and reliability. To resolve the contradiction between heat dissipation and sealing, and to effectively remove residual moisture inside the lamp, we propose a waterproof and moisture-proof LED lamp encapsulation and sealing structure. This innovative design aims to achieve highly efficient waterproof, moisture-proof, and heat dissipation performance, extending the lifespan of the LED lamp. Utility Model Content

The working time of the fan 1600 after each start can be set until the temperature inside the lamp housing 100 is lower than the threshold set by the temperature sensor 1200.

[0049] In this embodiment, the waterproof and moisture-proof LED lamp encapsulation and sealing structure, during use, forms a primary waterproof seal by contacting the first frame-shaped rubber pad 600 on the outer edge of the lamp cover 200 with the lamp housing 100. Simultaneously, the mounting side plate 220 on the top of the lamp cover 200 is inserted into the mounting grooves 102 on both sides of the lamp housing 100 and secured with bolts to enhance connection stability.

The air outlet of the fan 1600 faces the heat dissipation fins 720. The temperature sensor 1200 inside the lamp housing 100 monitors the temperature in real time. When the temperature exceeds the set threshold, the controller starts the fan 1600 to force heat dissipation until the temperature drops. During routine maintenance, the desiccant in the drying box 800 can be replaced by removing the cover 900, or the internal components can be inspected by removing the lamp cover 200.
