638nm Red Multi-Line 28-Lines Laser Module for Traffic Light and Crossroad Warning Laser Light

The 638nm Red Multi-Lines Laser Module—a specialized high-visibility optical solution engineered for traffic signal systems and crossroad safety warning applications. Optimized for outdoor harsh environments, this module delivers uniform, adjustable red laser lines that create clear visual warning zones for pedestrians, vehicles, and construction personnel, enhancing traffic safety and reducing accident risks.

Core Advantages for Traffic & Crossroad Warning

638nm Red Wavelength: Ultra-High Outdoor Visibility

• 638nm (±3nm tolerance) red light boasts superior atmospheric penetration and naked-eye recognition, outperforming other wavelengths in fog, rain, and haze—critical for 24/7 traffic warning in complex weather conditions.

• Standard 28-line laser output (customizable 20 lines) with line width ≤6mm@10m. The laser lines form a distinct "virtual warning zone" (effective range up to 150m) for crossroads, pedestrian crossings, or construction zones, grabbing drivers’ attention faster than traditional LED warning lights.

• Line uniformity ≥80% ensures consistent brightness across the entire projection area, eliminating fading or broken lines that cause warning blind spots.

Projection Parameters: Adaptive to Diverse Traffic Scenarios

• Line angle tuning: 110° horizontal projection range, supporting wide crossroad pedestrian warning (110° angle) without replacing the module.

• Power stepless adjustment: 20–50mW per line via PWM signal, adapting to day/night brightness differences—high power for sunny daytime, low power for nighttime to avoid glare.

• Focus lock design: Fixed focus at 5–150m working distance, maintaining sharp line quality without frequent calibration, ideal for unattended traffic equipment operation.

Safety Compliance & Easy Integration

• Class 3R laser safety compliance (IEC 60825-1): Safe for human short-term exposure at standard warning distances (≥5m), meeting global traffic equipment safety standards and avoiding eye damage risks for pedestrians/drivers.

• Universal mounting design: Flange + pole clamp dual mounting options, fitting 30–100mm diameter traffic light poles; 4-pin control interface (power + PWM signal) for seamless integration with traffic signal controllers or solar power systems.
