The TLED4 LED floodlight is a robust solution specifically designed for tunnel lighting, combining reliability, safety, and durability in challenging environments. Constructed in stainless steel, it is optimized to maintain consistent visibility for drivers, ensuring safety throughout tunnel infrastructures. TLED4 provides smooth luminance adjustment, allowing the human eye to adapt naturally to changing light levels, reducing glare and avoiding sudden dark areas, which is critical for maintaining safety in road tunnels. Its time-based regulation system, adjustable according to sunrise and sunset with separate day and night settings, ensures optimal visibility and responsiveness in emergency situations.
This tunnel floodlight supports a variety of mounting configurations to suit different tunnel layouts. For central or offset mounting, it offers asymmetrical optics (AS-xx) for reinforcement lighting and symmetrical optics (TS-xx) for both reinforcement and permanent lighting. For side mounting, a wide range of asymmetrical optics is available, including extra narrow beams (SV), narrow beams (STE-S / STU-S), medium beams (STE-M / STU-M), wide beams (STW / STA / STA1), and extra-wide beams (S05 / S07). The standard LED source operates at 4000K with a color rendering index (CRI) of 70 or higher, though other color temperatures are available. Classified in the photobiological safety EXEMPT GROUP, the LED modules achieve an efficiency of 185 lm/W at 140mA, Tj=85°C, and are rated for long-term performance with integrated optics and power supply. The luminaire carries IP66 ingress protection and IK08 mechanical resistance.
The TLED4 floodlight is constructed for reliability and ease of installation. It comes with integrated mounting brackets and a removable screen secured by clips requiring tools for removal. The heatsink is available in external (ED) configurations for larger versions (20M, 16M, 10M) and internal (ID) for smaller versions (8M, 4M, 2M). The luminaire supports mains connection via branch wiring for single-phase 220–240V 50/60Hz networks, with pass-through three-phase wiring available on request through an external junction box. Integrated main cables are standard, with additional options for fire-proof cables, separate network/DALI cabling, and IEC plug connections.
Surge protection is incorporated for up to 12kV, with optional SPD units rated 12kV-10kA, type 2+3, including LED signaling and a thermal fuse to safely disconnect the load at the end of its life. Control systems include fixed power (F), DALI digital dimming, constant light flux (FLC), and wireless single-point communication (WL), offering flexibility for smart tunnel lighting networks.
Constructed from durable materials, TLED4 features an extruded anodized aluminium heatsink, stainless steel fixing clips, and a high-precision optical system using 99.85% pure aluminium with a vacuum-sealed 99.95% surface finish, meeting A+ grade optical standards according to DIN EN 16268. The 5mm flat tempered glass screen provides high transparency while maintaining protection against environmental hazards. Cable glands are polyamide, and the gasket is polyurethane, forming a robust sealed assembly without a junction point.
With its combination of adjustable optics, robust construction, intelligent controls, and compliance with rigorous tunnel lighting standards, the TLED4 LED floodlight ensures reliable, safe, and long-lasting performance, making it an ideal solution for modern tunnel infrastructure and critical road safety applications.
