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 high-load environments, so maintaining high durability is essential. Various performance tests are conducted to ensure that the products are safe and reliable for customers.
