Ruairí O’Brien’s work in lighting design combines technology and design, science and art in theory and practice. To achieve special quality, technological understanding meets extensive knowledge and many years of experience in the fields of light, architecture and art.

The images show excerpts from Ruairí O’Brien’s lighting composition for Potsdam Unterwegs im Licht 2020, featuring the Brandenburg State Parliament, Nikolaikirche Church and Filmmuseum Potsdam, among others. “With an authentic concept, high-quality technology and a selective choice, you can achieve more in lighting design. To create poetic and exciting lighting atmospheres, you have to understand how time, space, materials, darkness and light can be brought together and how they can be set against each other.” Ruairí O’Brien

Lighting concept for the marketplace lighting

The new marketplace lighting in Freiberg broke new ground in urban lighting design. The unique light poles, specially designed for the historic Obermarkt Freiberg, combine in their own duality the technically functional object with the artistic light sculpture.

Innovative technology meets contemporary architecture, art meets science here. In addition to illuminating the marketplace in the evening, the light poles (reflector system) can also be individually controlled or dimmed depending on the need for use in the public space. During the day, dichroic glasses in the upper mast act in a solar geometric play with the sun, immersing the marketplace in a subtle, vibrant play of color. The light-architectural work of art tailor-made for the historic Obermarkt is completed by the illumination of the historic Otto fountain, the listed façade of the town hall as well as the water features and the unique granite seating furniture, also designed for the Obermarkt, which invite visitors to linger on the prestigious market square.

The lighting of the Obermarkt Freiberg was nominated for elisa – the Energy Efficiency Award Saxony 2014. With the nomination, the lighting of the Obermarkt Freiberg was distinguished by the expert jury as a practical example and highlighted as a multipliable, proven, sustainable as well as efficient example of Saxony or for Saxony as a corresponding incentive for energy-efficient solutions.

Hotel Bellevue

Hotel The Westin Bellevue Dresden

Lighting conference / banquet area

The goal was to convert to LED luminaires, replacing the existing lighting while retaining the luminaire locations. New LED ceiling downlights in warm white and cool white light replace the old luminaires with compact fluorescent lamps. They can be controlled in different lighting scenes depending on their use (whether a conference or an evening event).

The ceiling downlights in three different sizes, which were planned to match the interior design, blend in perfectly with the redesign of the rooms and ensure high lighting quality. At the same time, the new luminaires consume only about ¼ of the energy previously required. The maintenance effort can also be significantly reduced, as the previously frequent replacement of lamps will no longer be necessary in the future due to the long operating life of the LED luminaires.

The traditional Dresden hotel will receive a contemporary new lighting system that best supports its character as a modern conference and convention center as well as an event venue, both functionally and in terms of design.

Approved as a work of art, the hologram facade is a 16-meter-high, walkable day+night light sculpture. Different types of glass represent the identity and history of the city of Jena and at the same time make it possible to experience the valuable building in the interior as well as the surrounding exterior space, protect and at the same time show many details important for the preservation of historical monuments.

Lighting concept for the corridor areas

Within the measures for redesigning the public corridor areas, we developed an individual, attractive and energy-efficient lighting concept that generally increases the quality of stay and also takes into account the needs of older residents in particular.
Square surface-mounted luminaires with neutral white light illuminate the corridor area, ensure low shadow casting and very good facial recognition. Individual spots with warm white light above the apartment doors mark the entrances and serve as permanent lighting for orientation and safety. At the end of the long windowless corridors, an illuminated wall motif provides a special focal point. Through the interplay of the various elements, materials, colors and lighting moods, an attractive positive overall image was created in the public high-rise areas where people meet, whose optimistic basic mood welcomes residents and visitors.

House of architects, Dresden

Facade lighting seat Chamber of Architects Saxony

For the House of Architects in Dresden, headquarters of the Saxony Chamber of Architects, Ruairí O`Brien developed an appropriate and sophisticated permanent architectural lighting incorporating architectural elements on the building. The row of trees in front of the house shines in warm white, the vertical elements of the facade are illuminated with a subtle cooler light, and can also be illuminated in color for special occasions.

Memorial grove Zeithain

Exhibition lighting memorial Ehrenhain, Zeithain

With the literal planting of a new architectural-thematic heart, the “Walk-in Showcase” as a micro-architectural implantation in the historical RAD barracks preserved from the former Zeithain prisoner-of-war camp, the bridge between (structural) past and present is successfully built.
This glass building, a microclimatic soundproof object, thematizes not only time but also space in a special way and, as a time capsule in a place with a special auratic effect, creates a deliberate irritation that sensitizes the visitor to the exhibition theme. In the document house the visitor has the possibility to work on the offered thematic focal points in the operable micro-architectural information sculptures, which are executed in the same exhibition language, by himself, whereby new visual axes are offered again and again and an intensive reference to the content material is created with light/ mirrors.

Office lighting concept

Our lighting concept for the offices of the dean’s office of the medical faculty Carl Gustav Carus of the TU Dresden combines the functionality of lighting with attractive lighting design. In addition to everyday work activities, meetings and small conferences are also held in the rooms, as well as receiving guests. These different functional areas are precisely supported by the lighting. At the same time, the luminaires and the high-quality lighting design form an important part of the interior design of the dean’s office.

The basic lighting provided by wide-area ceiling luminaires is supplemented by individual task lighting for optimum working conditions. Wallwashers attractively highlight the artworks on the walls, and “floating” ring luminaires above the communicative areas create a visual link between the different rooms as a recurring element in a varied arrangement. Simple, flexible control of color temperature and brightness allows individual, attractive lighting moods to be created for many different situations.
