The Ultimate Guide to Explosion Proof LED Flood Light Materials/Specifications
Explosion-proof LED flood lights are built with robust, corrosion-resistant materials and must meet stringent performance and safety standards for operation in hazardous locations. Key elements include durable housing, specialized components, and internationally recognized certifications like ATEX, IECEx, and UL.
Key Materials
The materials are specifically selected to contain any internal explosion and prevent flames or sparks from escaping to the surrounding atmosphere.
Component Common Materials Rationale
Housing Copper-free aluminum alloy, stainless steel, or cast iron. Provides high mechanical strength, excellent thermal conductivity for heat dissipation, and superior corrosion resistance, especially in marine or chemical environments.
Lens/Cover Tempered glass or polycarbonate. Designed to be shock-resistant, vibration-resistant, and shatterproof, often sealed with silicone gaskets to ensure a high Ingress Protection (IP) rating.
Seals/Gaskets Silicone or Nitrile Rubber (NBR). Creates a tight seal to prevent the ingress of flammable gases, vapors, dust, moisture, and corrosive chemicals.
Hardware Stainless steel screws and external parts. Ensures integrity and resists corrosion in harsh industrial conditions.
Key Specifications
Performance specifications are critical for ensuring both safety and efficiency in hazardous environments.
Ingress Protection (IP) Rating: Typically IP66 or IP67 to protect against dust and high-pressure water jets.
Impact Resistance (IK) Rating: Commonly IK08 or higher to withstand mechanical impact.
Temperature Class (T-Class): Rated for specific ambient and surface temperatures to ensure they stay below the ignition point of surrounding flammable materials (e.g., T4, T5, T6).
Electrical: Input voltage ranges (e.g., 90-305VAC), high power factor (typically >0.9), and built-in surge protection (e.g., 10kV).
Photometric: High luminous efficacy (often >110 lumens/watt), specific CCT (color temperature) options (e.g., 5000K), and long lifespan (minimum 50,000 to 150,000 hours @ L70).
Hazardous Area Classification: Marked for specific Class/Division (NEC) or Zone (ATEX/IECEx) requirements.
