[0002] LED digital tubes are widely used in outdoor and industrial environments due to their high brightness, low energy consumption, and long lifespan. However, high humidity environments can cause performance degradation in LED digital tubes, and even lead to the following problems:

[0003] 1. Circuit failure due to moisture: When moisture enters the LED digital tube, it can cause short circuits and oxidation, affecting the lifespan of the LED.

[0004] 2. Brightness decay: When moisture enters the LED package, its optical performance is damaged, resulting in a decrease in LED brightness.

[0005] 3. Water seepage from the casing: Ordinary LED digital tubes do not undergo special moisture-proof treatment. In long-term high humidity environments, water can easily accumulate on the casing, affecting the display effect.

[0006] To address the above problems, this utility model proposes a highly efficient moisture-proof LED digital tube. Through a nano-level moisture-proof coating, moisture-absorbing material encapsulation, and moisture exhaust channel design, the moisture-proof capability of the LED digital tube is effectively improved, and its service life is extended.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This invention relates to a highly efficient moisture-proof LED digital tube. Through a nano-level moisture-proof coating, hygroscopic material encapsulation, and a moisture-venting channel design, it effectively prevents moisture from entering the LED digital tube. After 72 hours of testing in a high-humidity environment (95% humidity), compared to an unoptimized LED digital tube, internal moisture penetration is reduced by 90%, and the humidity level is reduced by 70%.

[0029] 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.

[0030] Please see Figures 1-4 As shown, this utility model provides a highly efficient moisture-proof LED digital tube, which improves its service life and stability in high-humidity environments by optimizing the moisture-proof structure. The following detailed description of this technical solution is provided in conjunction with specific embodiments.

[0031] Example 1

[0032] In this embodiment, the outer shell (6) of the LED digital tube is coated with a nano-level moisture-proof coating (2). This coating is composed of superhydrophobic nanoparticles with a thickness controlled between 0.1 mm and 0.5 mm. It can form a micron-level hydrophobic structure on the surface, causing water droplets to form spheres and roll off quickly, thereby effectively reducing moisture penetration into the internal circuit. After testing in a 95% humidity environment, after 72 hours, compared with the LED digital tube without the moisture-proof coating, moisture penetration was reduced by 90%, significantly improving the moisture-proof performance of the LED.

[0033] Example 2

[0034] To further reduce the moisture inside the LED digital tube, this embodiment incorporates a hygroscopic material encapsulation (3) inside the LED digital tube. Silica gel dry particles or molecular sieves are selected as the hygroscopic material, with a moisture absorption capacity of up to 50% of its own weight. It is stored in an independent encapsulation cavity (4) for easy maintenance and replacement. Experimental data shows that after 1000 hours of operation in an environment with 85% relative humidity, the internal humidity of the LED digital tube using this hygroscopic encapsulation solution is reduced by 70%, effectively preventing circuit damage caused by moisture accumulation.

[0035] Example 3

[0036] In this embodiment, a dehumidification channel (5) is designed on the outer shell (6) of the LED digital tube. This channel adopts a microporous dehumidification structure with a pore size controlled within the range of 0.1mm-0.3mm. Utilizing the principle of air convection, the moisture inside the LED digital tube can be smoothly discharged while preventing external moisture from entering, ensuring long-term stable operation of the circuit. In a continuous test of 1000 hours in an environment with 85% humidity, compared with LED digital tubes without a dehumidification channel, the internal moisture accumulation is reduced by 80%, effectively reducing short circuits and light decay caused by excessive moisture in the LED digital tube.

[0037] Example 4

[0038] In this embodiment, to further improve the moisture-proof effect, a waterproof and breathable membrane (8) is added inside the dehumidification channel (5) of the LED digital tube. This membrane is made of PTFE (polytetrafluoroethylene) material, with a pore size controlled between 0.1μm and 0.5μm, ensuring that moisture can be smoothly discharged while blocking external moisture from entering. After high humidity environment testing, the LED digital tube using the waterproof and breathable membrane has a 65% lower internal moisture content compared to the ordinary dehumidification channel solution, effectively preventing condensation and improving long-term moisture-proof capability.

[0039] Example 5

[0040] This embodiment also integrates an intelligent humidity monitoring and alarm system (10). This system monitors the humidity level inside the LED digital tube in real time through a high-precision humidity sensor and processes the data through a microcontroller (MCU). When the humidity exceeds a set threshold (80% RH), an alarm mechanism is triggered, and the surface of the LED digital tube flashes a warning signal. At the same time, the data is wirelessly transmitted to a remote control terminal to remind maintenance personnel to check and maintain it. Experiments show that this intelligent humidity monitoring system can detect and alarm in advance, reducing the circuit failure rate caused by excessive humidity by 60%, and effectively improving the stability of the LED digital tube in complex environments such as outdoor, industrial, and traffic signal displays.
