![]() The die cast aluminum heat sink provides optimum thermal management that ensures the light engine gets the best possible performance out of the LED technology. Sealed, IP66 rated LED engines come with a complete design that accommodates the mechanical, thermal, optical functionality in a watertight assembly. The durable and rugged construction of the JRE5 LED tunnel lights delivers superior resistance to corrosion, shock and vibration while providing. The precision molded TIR optics produce an asymmetrical pattern optimized to support driver's visual perceptions and improve vehicular movement in roadway tunnel and underpass applications. The LED arrays are overmolded with polycarbonate lenses to enhance light distribution and shield the LEDs from the corrosive degradation of environmental elements. The modular light engines utilize Cree or Osram LEDs which are known for their high luminous efficacy, light quality, color stability and lumen maintenance at high temperatures and high drive currents. The JRE5 product family provides a complete and scalable offer from 45 to 120 watts in one or two module configurations. The luminaire design of the JRE5 LED tunnel lights embraces the modular concept that allows for excellent scalability, easy component replacement and maintenance, and effortless upgrades to future LED generations. The JRE5 series has been developed to address the special challenge of tunnel lighting which requires not only reliable and energy efficient operation throughout the entire life of the system, but also the stringent standards of glare control and uniformity of the lighting on the road surface. ![]() The tunnel lighting system capitalizes on an optimized combination of high performance LEDs, high reliability drivers with topology that yields the highest efficiency, and precision engineered optics that specifically developed for superior optical control. Both recessed and surface-mounted versions were used, with each luminaire having 11W of power.The JRE5 Series LED tunnel lights provide a lifetime solution to tunnel and underpass lighting with their optimal performance, reliability and durability that align with industry's best practices. All in all, Lumous Lighting supplied 380 bridge luminaires for underpass lighting for southwest Finland. The installation began in October 2010 and was finished in April the next year. For example, the lighting intensities are exactly as we wished´, he says.Īccording to Arvonen, the main reasons for selecting the LED lights was the large amount of provided light and the energy efficiency of the lights, the low level of maintenance, long lifespan, and protection against vandalism. ![]() Marko Arvonen, the Department Manager of street lighting and installation services at Raision Sähkö-INSTO, says that the Lumous Lighting LED lights have fully lived up to the expectations. The actual end-customer was the Centre for Economic Development, Transport and the Environment of Southwest Finland, which is also responsible for maintenance of pedestrian and bicycle trails. Raisio Sähkö-INSTO carried out the installations. Lumous Lighting LED luminaires have been installed in Raisio, Mynämäki, Somero, Salo, and Nousianen. The new Lumous Lighting LED bridge luminaires have replaced the old mercury vapor lamps that in the past shed light on the cyclists and the pedestrians. Dozens of pedestrian and bicycle underpasses across southwest Finland are now enjoying bright and sustainable LED lighting.
