The best of both worlds Tunnel & Underpass lighting

TRIPLE-C The perfect balance With LED technology in road tunnel lighting we can offer a new balance between Costs, Comfort and Care. The T-line road tunnel lighting luminaire integrates the quality and safety achievable with fluorescent linear lighting with the efficiency and Total Cost of Ownership of high pressure sodium point source lighting. Therefore, T-line perfectly suits Indal’s TRIPLE-C philosophy; providing the perfect balance between Costs, Comfort and Care. COSTS COMFORT CARE A unique Total Cost of Ownership proposition: High-quality cool white LED delivered by a linear lighting...

T-line Combining the benets of uorescent linear lighting with the advantages of point source lighting Indal has developed a series of linear LED luminaires primarily for road tunnel lighting applications. The result is T-line: road tunnel lighting combining the ‘Comfort’, quality and safety of a fluorescent linear scheme with a Total ‘Cost’ of Ownership of a high pressure sodium point source scheme, with the added benefit of taking greater ‘Care’ of the environment due to LED technology. In road tunnels, a fluorescent linear solution is the preferred High pressure sodium point source...

T-line tunnel lighting luminaire The T-line luminaire series is initially available in two different types. The 40 LED version for tunnel interior lighting and the 56 LED version for entrance lighting. Generic T-line specications LED module housing: Optical system: The main housing and lens cover are Clear plastic DIRECTA™ lenses, adhered manufactured from a high quality extruded to lens cover plate by automated aluminium (AlMgSi0.5 acc 6066 T66) with silicone sealing process. The light an anodised neutral colour finish (> 25µm distribution has been optimised for road thickness and sealed...

Design Light weight, low-prole and at free-draining surfaces, no cooling ns. Connectivity Suitable for plug-and-play installation. The driver is mounted remotely for ease of maintenance. Protection Corrosion protection system and IP 66 ingress protection. Optics Lens and LED are integrated, resulting in high lumen output performance and an accurate light distribution. 5

T-line characteristics Easy installation and maintenance T-line luminaires are compact and therefore easy to store and To prevent corrosion resulting handle. Their shallow construction means they can sometimes from dissimilar metals, the be installed over-lane, where traditionally a normal fluorescent mounting system provides total luminaire would be unsuitable. This results in a lower luminaire isolation between the LED module quantity, reducing installation costs and energy consumption. and the support structure. Each luminaire is fitted with a flying lead and plug, providing T-line LED’s...

Advanced REVOLED technology ™ T-line is based on REVOLED™ technology developed by Indal. Thanks to REVOLED™, T-line offers all the benefits of LED light sources. Powerful, high-quality LED’s, the COO-LED™ cooling system and DIRECTA™ lenses give you excellent light quality, high energy savings and low CO2 emissions. REVOLED™ High-quality power LED’s REVOLED™ uses powerful, high-quality LED’s that contain no mercury and emit no UV radiation. They provide efficient, uniform and comfortable cool white light with superb colour rendering. This improves visibility of vehicles and objects in...

COO-LED™ For increased LED life span COO-LED™ delivers superior temperature control by combining low current LED’s with a large cooling surface that’s an integral part of the luminaire housing. LED’s are bonded directly to the outer skin of the luminaire eliminating any insulation in the heat dissipation path, which not only ensures high LED efciency, but also provides an extremely long system life span. DIRECTA™ Lenses for high optical efficiency and accuracy Patented DIRECTA™ clear lenses are integrated into the luminaire housing with no additional cover required. The result is high...

By clever application of the unique characteristics of the T-line luminaires the lighting designer can make additional savings compared to traditional lighting schemes. Precise L20 control Entrance lighting Improved lighting system efciency Stage very sunny over-lighting required lighting level Stage sunny Stage clouded Dusk Day Dawn Hours T-line is fully dimmable and if combined with precise L 20 control (like the The above graph demonstrates the several switching stages for entrance i-TunneL® C&M system), it can provide the exact level of light needed at lighting. The vertical line shows...

Compensation of depreciation Like any light source, LED’s are subject to lumen depreciation over their lifetime. But with LED’s this is very predictable. In combination with T-line’s continuous dimming feature, the system can be designed to compensate for LED depreciation. So even as the light output of the luminaires weakens over time, depreciation compensation ensures a constant level of cool white light and prevents significant over-lighting. Lower lighting levels T-line offers extremely high uniformity levels across tunnel surfaces, including the walls. It also provides excellent visual...
