Introduction
Silicone extruded LED strip lights have become increasingly popular due to their flexibility, durability, and energy efficiency. However, for outdoor or underwater applications, it is important to ensure that the LED strip lights have a high level of waterproofing. The IP68 rating is the highest level of waterproofing, indicating that the LED strip can be submerged in water beyond one meter depth without damage.
The Significance of Waterproofing
Waterproofing is crucial for LED strip lights used in outdoor or wet environments. Without proper waterproofing, water can penetrate the LED strip and cause electrical hazards, short circuits, and even fires. Therefore, waterproofing is not only important for the safety of the users but also for the longevity of the LED strip lights.
The Process of Silicone Extrusion
Silicone extrusion is the process of pushing molten silicone through a die to create a continuous profile with a fixed cross-section. The silicone extrusion process is widely used to produce various silicone products, including LED strip lights. In the case of LED strip lights, the silicone extrusion process is used to encapsulate the LED chips and wiring, providing a waterproof layer around the components.
The Advantages of Silicone Extrusion
Silicone extrusion has several advantages over other encapsulation methods. Firstly, silicone is highly flexible, allowing it to withstand extreme temperatures and harsh environments without cracking or breaking. Secondly, silicone is resistant to UV radiation, meaning it will not degrade over time due to exposure to sunlight. Finally, silicone is an excellent electrical insulator, protecting the LED chips and wiring from water and other contaminants.
The IP68 Waterproof Rating
The IP rating system is used to classify the degree of protection provided by a device or enclosure against the intrusion of solid objects, dust, and water. The first digit in the IP rating represents the level of protection against solid objects, while the second digit represents the level of protection against water. An IP68 rating means that the device is dust-tight and can be submerged in water beyond one meter depth without damage.
How Silicone Extrusion Achieves IP68 Waterproofing
To achieve IP68 waterproofing, silicone extruded LED strip lights undergo rigorous testing. The LED strip is submerged in water for a specified period to determine its ability to withstand water intrusion. If the LED strip passes the test, it is given an IP68 rating. The silicone extruded layer around the LED chips and wiring provides a waterproof barrier, preventing water from penetrating the components.
The Role of Additional Waterproofing Measures
In addition to silicone extrusion, other waterproofing measures may be used to further enhance the waterproofing of LED strip lights. For example, some LED strip lights have an additional layer of protective coating or a silicone sleeve around the silicone extruded layer. These additional measures can provide extra protection against water intrusion and prolong the lifespan of the LED strip lights.
Conclusion
Silicone extruded LED strip lights are popular due to their flexibility, durability, and energy efficiency. The silicone extrusion process provides a waterproof layer around the LED chips and wiring, protecting them from water and other contaminants. The IP68 rating is the highest level of waterproofing, indicating that the LED strip can be submerged in water beyond one meter depth without damage. With the advancement of silicone extrusion technology, we can expect more innovative and reliable LED strip lights with superior waterproofing properties in the future.
