Durable Prism-pattern Moulded Glass Lens For Directional Led Streetlights

Durable Prism-pattern Moulded Glass Lens For Directional Led Streetlights

1. Material:

   • Primary: High-grade Borosilicate Glass (or similar engineered glass).

   • Key Feature: The lens is Moulded (precision-formed under heat/pressure) into its specific shape and optical pattern.

2. Key Properties:

   • Durability: Resists weathering, UV degradation, thermal shock (from LED heat/cold nights), abrasion (sand, grit), and chemical corrosion (pollution, de-icing salts). Significantly outperforms plastic alternatives.

   • Optical Precision: The Prism-Pattern is moulded with high accuracy, ensuring consistent light control. Glass offers superior optical clarity and stability over time.

   • Thermal Stability: Maintains shape and optical properties under high operating temperatures generated by LEDs, preventing deformation ("creep") common in plastics.

3. Primary Function:

   • Directional Light Control: The moulded Prism-Pattern is the core functional element. It precisely refracts and redirects light emitted by the LED chips.

   • Beam Shaping: Creates a specific photometric distribution (e.g., Type II, III, IV, V as per IESNA standards) suitable for roadway illumination – typically a batwing or asymmetric pattern.

   • Glare Reduction: Minimizes light spill above the horizontal plane and directs light onto the target area (road, sidewalk), enhancing visual comfort and safety.

   • Efficiency Maximization: Minimizes wasted light (uplight, spill light into unwanted areas), ensuring maximum usable lumens reach the intended surface.

4. Applications:

   • Core Use: Directional LED Streetlights for public roads, highways, and expressways.

   • Key Fixtures: Integrated into luminaires designed for area lighting with specific beam control requirements.

   • Other Uses: Perimeter lighting for large facilities (airports, ports, industrial sites), campus pathways, parking lots, pedestrian zones, and tunnel entrances/exits – anywhere precise, efficient, and glare-controlled directional illumination is needed.

   • Retrofit/New Build: Suitable for both new LED streetlight installations and retrofitting older lighting systems.

In essence: This lens is a robust, long-lasting optical engine made from moulded glass. Its defining prism pattern meticulously shapes the raw LED light into a controlled, directional beam for street and area lighting, maximizing efficiency, minimizing glare and light pollution, and ensuring reliable performance for the lifespan of the LED fixture. Its durability and precision optical control are its key differentiators over plastic optics.
