Explosion-Proof LED Lightings
■ What is AC-IN Explosion-Proof LED Lighting?
Unlike conventional explosion-proof lighting (a lighting designed for environments with explosive gases or combustible dust), this product adopts AC-IN technology, which does not use an AC/DC converter (a device that converts alternating current to direct current). This technology provides advantages that conventional products could not achieve.
■ Features
• Explosion-proof
Excellent heat dissipation design allows explosion-proof certification under standard temperature conditions.
• Heat Resistance
Heat resistance has been tested in accordance with UL Standards. The product is applicable to high-temperature environments up to 100°C.

■ DC LED Type vs. AC LED Type
■ What is Explosion-Proof?
In environments where flammable gases or liquids are present, electrical sparks can cause explosions or fires. Therefore, electrical equipment used in such areas must have explosion-proof features.
■ Track Record of Implementation
• AC-IN Explosion-proof LED Lighting is applicable to various extremely harsh environments, such as petrochemical industries and marine industries involving underwater applications.
■ Efforts to Ensure High Quality
Explosion-proof lighting is expected to be used in environments with heavy loads, so maintaining high durability is essential. Various performance tests are conducted to ensure that the products are safe and reliable for customers.
