Museum of Light

Designing a Light Museum was an exciting and fulfilling topic for the students. It allowed them to explore the inspiring relationship between light and science, art, technology, and architecture while reflecting on their Egyptian heritage. The project’s location on a peninsula near the monuments of Abu Simbel, which celebrate sunlight during the winter and spring solstices, made it an even more fitting endeavor.

Light, a universal topic with transcultural significance, touches on profound subjects like poetry and philosophy as well as pragmatic concerns like energy, health, and economics. There are very few true “Light Museums” in the world. Most often, technical or science museums cover this topic, or art museums showcase artists’ interpretations of light. However, no museum or institute tells the story of light in all its consequences and expressions through a holistic experiential concept from building to exhibition. Abu Simbel, with its historical and mythological links to the power of light and its dam generating the country’s electricity, is an ideal location.

The question arises: can we construct a new building in such a historical context? My answer is unequivocally yes, but it leads to a finer question: should the new building be visible or hidden? This is a common challenge for architects working in historical contexts. The students’ excellent answers to this are showcased in the exhibition.

The project aimed to raise awareness among the students about the economic and social benefits that first-class contemporary architecture can bring to local communities. Long-term sustainability involves providing opportunities for people to thrive, encouraging local businesses to grow, and attracting outside investments. The project also included a Life Long Learning Institute, where visiting researchers and artists working with light could engage with local people, children, and youth projects. This is how architecture can extend its program to support regional development, providing a space for education, knowledge, tourism, business, and human exchange.

The bravery of repositioning the monuments to construct the Aswan Dam set a precedent for extending the story with a new visionary attraction of contemporary architecture, linked to Egypt’s ancient and modern history.

The bachelor project is the highlight for the students, marking the end of a long and sometimes stressful period of study. The rewarding feeling of deep achievement follows and cannot be taken away. Congratulations to all students for their enthusiastic work, and special thanks to my teaching assistants for their support this year, Abdelrahman Ghoneim and Marian Ghali.

“Eternity”- Ruairí O’Brien competition entry for the Frechen Central Memorial

Ruairí O’Brien’s work of art “Eternity”, with its striking and at the same time simple elements in a material and metaphorical sense, forms a dignified space for remembering all victims of the National Socialist tyranny. The two vertical masts and the line of light floating horizontally between them mark and house the real Fre¬chen green space; At the same time, through the immaterial spaces in between, they inspire an unlimited mental wandering between times, spaces and events. A line crosses the sky and illuminates the ground below. At the same time, reference is made to the spatial and temporal significance of the topic. The meta-level created in this way, which can be perceived haptically / visually / with the senses, forms an expansion space and yet an ensemble with the information board designed for concrete, authoritative verbal information about the history.
“Simplicity gives complexity” – Simplicity allows and harbors great complexity here.
The work of art brings public attention to the central memorial site. It marks this central square as a central memorial day and night and symbolically refers to the places where the events took place. The work encourages you to linger, to pause, and offers flexible space for mediation work by institutions, groups and individual actors.
The line of light (bridge) that invites you to look, think and remember, it remains, it is always there.
The work of art has a noticeable day and night effect. Depending on the viewer’s location, depending on the time of year and day, depending on the weather, lighting conditions, environment and individual visitor’s condition, it develops its effect – sometimes more delicate, sometimes more intense, always with a long-distance and close-up effect.
Anyone who approaches the work of art opens up different perspectives and perceptions. Viewers are reflected in the masts, their gaze connecting their own self with the surroundings and the subject matter. The environment is reflected in it, light is reflected and directed.

Lighting shade roof GUC

Lighting shade roof GUC

Light and Shadow Concept

Our lighting concept for the roofing of the central square on the campus of the German University in Cairo is intended to improve the evening use of this popular meeting place at the university.
During the day, the space is primarily used to provide catering for students and employees. It is also a place for meetings and presentations. Current information about university operations runs on the large screen. However, especially in summer, it is often not possible to use the space during the day because the temperatures are too high and people seek closed rooms or the shade. With this in mind, Ruairí O’Brien . Architects designed variants for attractive shading.

Further information can be found at the following link.

The users look for shade under the roof during the day and light in the evening. This will be possible in the future thanks to our lighting concept. Thanks to the attractive lighting, the roof now also offers extended usage options for the food court into the evening hours. The lights, individually designed for the shade roof, with flexibly changeable color temperatures and individually adjustable illuminance levels ensure optimally coordinated lighting on the usage area, depending on the type of event. At the same time, the underside of the roof is attractively presented so that people enjoy spending time under it.

Lighting concept for the design for the outdoor areas of the German Embassy in Ireland

In this project, our three focus areas of architecture, light and art/spatial art complement each other in an ideal combination for solving a demanding task. Suggestions were sought to give the courtyard area, which had been severely affected by various renovation work on the embassy building, a representative appearance again in the short term. As an interim farm improvement, we have developed suggestions for effective and easy-to-implement measures that give the farm area an attractive design and enable it to continue to be used.

Our concept proposals with a design idea that spans the different courtyard areas serve as the basis for the redesign. The total area of ​​the farm is approximately 1,200 m².

Enthusiasm for soundless music light composition at “Unterwegs im Licht”

Last Saturday (20.1.), the international team of light artist and architect Ruairí O’Brien accompanied the numerous cultural players in the center of Potsdam at the 10th anniversary of “Unterwegs im Licht”.
From dusk until late in the evening, O’Brien’s artistic soundless-music light composition moved simultaneously and synchronously through the color wheel of spectral light colors on all the buildings – including DAS MINSK, the Museum Barberini and the Garnison Church, which is currently being rebuilt. The rhythmically and visually varied choreography made it possible for children and non-children to experience color theory in the most entertaining form. In addition to the inspiring overall composition, which offered surprising changes of rhythm and sound in the form of visual sensory impressions, the laser show “Journey through the Stargate” in the city canal and the final performance on the Alter Markt were among this year’s highlights, according to numerous visitors.
Each of Ruairí O’Brien’s compositions for “Unterwegs im Licht” is unique in terms of the city-related themes, the facades involved, the color palette, the intensity and the tempi. Part of the architect and light artist’s special signature is to make each room and each building tangible in its individual character.

Marketplace Light Planning of the Old Cotton Mill in Flöha, Saxony, Germany

Marketplace Light Planning of the Old Cotton Mill in Flöha, Saxony, Germany

Construction begins Autumn 2023.

Flöha’s “Old Cotton” is a historical landmark that has played a significant role in shaping the region’s identity and economy for over two centuries. Established in 1809 during Napoleon’s time, the spinning mill evolved into one of Germany’s largest and most modern factories by the late 19th century. Although production ceased in 1994, the city of Flöha recognized the cultural and economic value of the brownfield site and launched the “City Center” project in 2001 to revitalize the area.

The name “Old Cotton” represents the rich legacy of Saxony’s oldest spinning mills, which operated continuously for an extended period. The Heritage Quarter holds a special place in the city’s history, and the iconic industrial architecture of the old cotton mills continues to define Flöha’s identity and image.

Moreover, the entire area, including the adjacent park and the industrialist’s villa “Immenhof,” enjoys monument protection. To support the city’s vision of developing the heritage buildings quarter of the old cotton mills as the new city center and market square, Ruairí O’Brien.Lichtdesign has created a unique lighting concept. This concept accentuates the beauty of the site and complements Flöha’s ambitious plans to create a vibrant cultural hub in the heart of the city.

Lively center Baumschulenstrasse-Köpenicker Landstrasse

The Integrated Urban Development Concept (ISEK) forms the basis for the development of the Baumschulenstrasse – Köpenicker Landstrasse area as part of the Living Centers and Quarters (LZQ) funding program. The aim is both to strengthen the district center around Baumschulenstrasse and to improve local supplies throughout the entire funding area. An attractive design of the public space and the existing buildings is a central component of an attractive commercial street, as is an appropriate external representation of the commercial businesses located in the ground floor zones. This design guide was developed to support local businesses and property owners in improving the appearance of their respective businesses and working towards a coordinated overall impression.

Competition entry, 3rd place

The lighting concept is an essential part of the competition entry “Points and Lines”, which consists of two elements: Information points and light lines for the paths between them.

The concept includes the didactic idea that the light lines guide the visitors and the information pillars (points) mark the individual stations.
The info pillars are light sculptures that represent gathering points where history is explained to visitors during guided tours.
The guiding light lines lead to these information points, provide the power supply and at the same time ensure optimal illumination of the space.

Both the design of the information modules and the lighting stand out clearly from the historical surroundings and thus convey a distance to the original structural environment. The historical rooms are viewed in the light of today, while the self-sufficient exhibition elements show the entire surrounding space.

We are pleased that our light-oriented exhibition concept was able to achieve an excellent third place in this competition with numerous renowned participants.

“Soundless Music”

On the road in the light. But safely!

On the third weekend in January, our LICHT composition “Soundless Music” was performed in Potsdam’s city centre. With the concept developed especially for “Unterwegs im Licht 2022”, Potsdam’s city centre was staged in a composition of colours during the evening hours, from Friday (21 January) to Monday (24 January), thus expressing the universal process of THERMODYNAMICS.

Beginning with blue tones on Friday, ending with red tones on Monday, the LIGHT composition worked with 18 buildings, each in turn with 24 light scenarios that harmonise and interact with each other to create an immersive walk through the “Gesamtkunstwerk” of public space, architecture, light and time.

Kicking off on Friday, the beauty of the cold winter months was celebrated in calm BLUE and INDIGO combinations, which gave way to the optimistic GREEN of spring on Saturday and were replaced by the WARM summer joy of YELLOW and ORANGE tones on Sunday. The dynamic process concluded on Monday with a more reflective backdrop of DARK RED, accompanied for the FINALE with lighting moods from all the MAIN COLOURS of the colour spectrum.

“We have not forgotten you”.

This LICHTKUNST action was linked to the intention of the state capital Potsdam to convey to its citizens and its cultural institutions that it has not forgotten the importance of CULTURE in the city and the relevance of all those active in the cultural scene, even in these difficult times. For all, this weekend celebrated the beauty of life and art in and with (light) culture.

The illumination was realised by the following partners: Landeshauptstadt Potsdam (organiser), P3 Projekt GmbH (organisation), Ruairí O’Brien . Lichtdesign (lighting concept), TLT Event AG (technical implementation)

Lighting Design Concept Bahnhofstraße Lichtenrade, Berlin

Lighting concept Bahnhofstraße Lichtenrade

Lightwalk in Berlin

The planning of public lighting for the traffic areas (street) and secondary areas (pedestrian and recreational areas) is an essential part of our lighting concept for Bahnhofstraße Lichtenrade. The street and sidewalk lighting is coordinated with the superordinate lighting concept of the city of Berlin.

In addition to the use of light as a design tool to improve the appearance of public spaces and to increase the quality of stay in Bahnhofstrasse, lighting always serves first to ensure traffic safety. Uniform illuminance, an emphasis on conflict zones and the avoidance of disturbing light (glare) increase safety for road users and support the quality of stay in the urban space. The subspaces (microspaces) defined in the lighting master plan can optimally fulfill their function of structuring the public space, increasing attraction and dwell time even in the dark half of the day or year. Consideration was also given to the future redesign of the commercial street and the lowest possible maintenance and energy costs while optimally fulfilling the lighting task.

Illumination of the main avenue of the university hospital

The lighting concept for the main avenue developed by Ruairí O’Brien is the first part of the associated development of the lighting master plan for the Carl Gustav Carus University Hospital in Dresden. The new lighting creates a uniform and contemporary appearance with high-quality light that takes into account the individual requirements of the individual sections of the approximately 500m long main avenue of the clinic and the immediately adjacent areas. In conjunction with the redesign of the listed avenue, an attractive and forward-looking appearance is created.

Lighting scenes

  1. Early night hours (lighting plan at the top): full lighting level according to the programmed power as per the lighting concept.
  2. Late night hours (centre images): reduced, energy-saving lighting

By means of phase-controlled half-night switching (HNS), the luminaires are switched to reduced power operation (reduced luminous flux) during the night. This ensures a minimum lighting level to guarantee safety and orientation on the square. In areas without use or individual luminaires that primarily serve spatial modelling and atmosphere (e.g. at the “Schaukelwäldchen”), the lighting can be switched off completely in consultation with the City of Mannheim. Even in the late half of the night, the path area remains illuminated in such a way that the standard-compliant illuminance is maintained. Optionally, intelligent dynamic lighting control with radio-networked luminaires can be used to make the lighting dependent on use. To prevent vandalism and increase cleanliness and safety, the lighting in the kindergarten area is controlled by presence detectors.

Early night atmosphere

The downward light prevents a boring and monotonous lighting atmosphere and creates a lively carpet of light with nuances of light and dark. The luminaires can also set accents, e.g. grazing light on tree trunks without scattered light into the night sky. The tree-like shape of the selected luminaires matches the park landscape.

Late night atmosphere

According to the use, rear park areas are darkened, the path remains illuminated. The square is in darkness and only the main path is fully illuminated, for safety when crossing and for orientation.


Reduced illuminance levels and directed light from above at small half-scatter angles maximally reduce unwanted stray light and prevent unnecessary light pollution. The warm light colour of the luminaires in the square creates a stimulating and calm atmosphere. In addition, this lighting offers the highest possible level of insect and bird protection due to its low blue component. For optimal colour recognition and improved facial recognition, to increase safety and the subjective feeling of security, the area of the passageway and the café is illuminated with 3,000 K.
