Explosion-Proof Borosilicate Glass LED Lenses for Mining Lamp

1. Material:

• Borosilicate Glass (e.g., Schott Borofloat®): Engineered for extreme environments with low thermal expansion (CTE: 3.3 × 10⁻⁶/K) and high chemical resistance.

• Flame Path Design: Precision-machined edges/threads to contain explosions via controlled flame quenching.

2. Key Properties:

• Explosion-Proof Certification: Complies with ATEX/IECEx Zone 1 and MSHA standards. Prevents ignition of methane/dust mixtures.

• Impact Resistance: IK08+ rated to withstand 5J+ impacts from rocks, tools, or falls in mines.

• Thermal Shock Resistance: Handles ΔT > 200°C without cracking (e.g., sudden water contact on hot lenses).

• Chemical Durability: Resists corrosion from acidic/alkaline mine atmospheres, humidity, and cleaning solvents.

• Optical Clarity: >92% light transmission with anti-glare treatment for clear visibility in low-light/dusty conditions.

• Flame Retardancy: Non-combustible material (Class A1 fire rating).

3. Primary Functions:

• Hazard Containment: Seals LED components, preventing sparks/heat from escaping to ignite flammable gases (e.g., methane).

• Optimal Light Output: Maximizes LED efficiency with minimal lumen loss for extended battery life.

• Environmental Protection: Blocks dust, water (IP68), and corrosive agents from damaging electronics.

• Worker Safety: Eliminates lens shattering (tempered construction) and reduces glare-induced eye strain.

4. Applications:

• Mining Cap Lamps: Primary lens for underground LED cap lamps (head-mounted).

• Fixed Hazardous Lighting: Explosion-proof mine tunnel fixtures, refuge stations, and conveyor belt lighting.

• Portable Inspection Lamps: Handheld mining lamps for maintenance/emergency use.

• Coal/Iron Ore/Gold Mines: Certified for methane-rich (Group I) and dust-heavy (Group II/III) environments.

• Tunneling & Drilling Rigs: Vibration-resistant lenses for heavy machinery lighting.
