LED Interior Lighting for the Helsinki Artic Trams
In Finland, Teknoware implemented interior lighting using modern LEDs in forty Artic Helsinki trams. Each car was fitted with two direct and two indirect lines of lights. Special attention was paid to energy efficiency in designing the lighting, which was achieved through an active dimming function, where a Lighting Control Unit (LCU) adjusts the brightness of the vehicle’s interior lighting by means of sensors according to external lighting conditions. Driver safety is increased by LED spotlights that turn on and off gradually in order to prevent glare. The rear car’s outer arc is accentuated with curved, interior LED lights.
