Professional marine lighting by OSRAM for the widest variety of requirements

Modern cruise ships are a mixture of a luxury hotel and a ship fit for the high seas. The guests on board want relaxation and exciting experiences, whereas shipping companies demand robust, efficient and flexible solutions in all technical areas. OSRAM is one of the world's largest producers of light and provides professional lighting solutions in the area of maritime lighting for the wide range of requirements on board.

Maritime lighting requirements are highly diverse

Cruise ships are imposing, elegant and luxurious. Lighting below and on deck needs to be optimized for completely differing requirements and it must also be tough and energy-efficient. It has to do conjure up an appealing atmosphere in the event areas, for example, reliably direct guests through the large number of corridors, have a relaxing effect in cabins, and provide specific lighting requirements in machine rooms and cold stores.

Two ships belonging to the North American shipping company Norwegian Cruise Line (NCL), the "Norwegian Getaway" and the"Norwegian Breakaway", were equipped with state-of-the-art lighting technology by OSRAM in March 2013 and January 2014. By using modern lighting components on board, supplied by OSRAM and its subsidiary Traxon Technologies, both ships will be consuming 18% less energy for lighting in the future. Seen on average, the savings potential is even higher: Around 25 to 40% of the energy requirements of a cruise ship are needed for lighting, depending on the type of ship and the application, and excluding the drive.

17.5 kilometers of flexible LED modules installed

From now on, the approximately 4,000 passengers on the 320 meter long steamers proceed through discreetly illuminated corridors to their cabins, enjoy intelligently designed lighting atmospheres in the restaurants and allow themselves to be pleasantly surprised in the theater with highly colorful and spectacular lighting effects. 60,000 to 80,000 light points, ranging from simple spotlights to chandeliers and disco lighting, have been installed in each ship. In addition, around 30,000 meters of cable have been laid. Approximately 17.5 kilometers of flexible LED modules and other luminaires fitted with OSRAM lamps were installed on board. Depending on the application, either halogen Eco, DULUX energy-saving or PARATHOM LED sources radiate light.

"We benefit from the ever-expanding market for cruising because we are able to provide shipyards and shipping companies with energy-efficient and diverse lighting solutions, ranging from lamps with their control gear and flexible LED systems and luminaires to complex, dynamic lighting solutions supplied by our subsidiary Traxon Technologies," emphasized Andreas Bär, Head of Marine Lighting at OSRAM. OSRAM, in partnership with the Meyer Shipyards in Papenburg, Germany, have been developing energy-efficient and cost-saving solutions for marine lighting since 2007.

High standards with safety regulations

Stephan Schmees, Project Manager at the shipyard: "When it comes to light we focus on three factors: Energy efficiency, cost and the emotional effect to be created. We emphasize and underline the atmosphere and architecture of the ship with our lighting solutions. The people need to be inspired as soon as they come on board." In addition, all safety regulations have to be complied with, stated the marine expert. "We have very high standards for example when it concerns the salt water resistance of luminaires and fire protection. Together with OSRAM we've made lots of progress in the past few years in the LED sector, and have continued to develop the portfolio."

Energy efficiency of LED technology at the center of things

Schmees, in particular, places high value on the energy efficiency of LED technology. "With each new generation of ships we install an ever larger number of LEDs". This consistently saves more energy, which is an important factor because the energy is self-sufficiently generated on board. But snares lie in wait. In the cabins, the LED technology is installed behind mirrors, in the shower units, behind curtains and in the light coves as well as in other areas. "With such applications we have to take care where we accommodate the control gear, how much heat is dissipated and how the luminaires reflect from the ceiling material." Added to this are the special requirements created by innovative materials that have come about only in the past few years with the use of LED technology. "In the beginning we had particularly to take into account the special methods of mounting and also directly consider the need for replacements at the maintenance intervals," explained the OSRAM engineer Martin Jost, responsible for projects in the Meyer shipyard.

For the project manager Schmees though, the benefits of LED technology are obvious. "It's more energy efficient because it consumes less electricity and at the same time develops less heat. This is why we don't have to cool as much. Also, the LEDs are less sensitive and a lot more durable with around 50,000 operating hours."
