In signal lighting, clarity and durability are paramount. Our Round Glass Signal Lenses are engineered to withstand the harshest outdoor elements while delivering precise optical performance.
Manufactured via high-pressure pressing, these lenses feature a prismatic (Fresnel-like) inner surface that collimates light from the source, projecting a strong, clear signal visible over long distances—essential for Traffic Management, Railway Systems, and Marine Safety.
Why Choose Glass Over Polycarbonate?
- Zero UV Degradation: Unlike plastic lenses that yellow and craze under the sun, glass remains permanently clear, ensuring signal colors (Red/Green/Amber) stay true for decades.
- Thermal Stability: Capable of withstanding the intense heat of high-wattage halogen bulbs or high-output LEDs without melting or deforming.
- Scratch & Chemical Resistance: Impervious to sandblasting from wind, salt spray in marine environments, and industrial cleaning solvents.
Technical Specifications
- Material: Borosilicate Glass 3.3 (for high heat/thermal shock) or Soda-Lime Glass (for standard LEDs).
- Optical Design:
- Inner Surface: Specialized Ribbed / Fluted / Fresnel pattern for beam control (Spreader or Spot).
- Outer Surface: Smooth and convex for self-cleaning (rain washes away dirt).
- Dimensions: Available in standard signal diameters:from 60 to 400mm
- Colors: Clear (Standard), Red, Green, Amber, Blue (Colored glass available upon requested).
Applications:
- Transportation: Traffic Lights, Pedestrian Crossings.
- Railways: Trackside Signals, Shunt Signals, Locomotive Headlights.
- Aviation: Runway Edge Lights, Taxiway Lights.
- Marine: Navigation Buoys, Port Beacons.
- Industrial: Crane Warning Lights, Tower Obstruction Lights.
Customization Capability
- Sample Duplication: Need to replace an obsolete lens for a vintage railway signal or antique spotlight? Send us the original, and we can reverse-engineer the mold.
- Volume Manufacturing: Automated pressing lines ensure consistent quality for large government or municipal tenders.
