Rising protests in recent years to address ecological, social and political issues have motivated artists and activists to reflect their strategy of interventions. In this connection light has become an attractive element to create striking images and videos to enhance press and social media communication. Different new forms have emerged. Previously using a sea of candles to show solidarity and to express unity has been replaced with bright LED flashlights from mobile phones. Projection with graphics and text enable artists and activists to underline their core messages or even to temporarily take possession of iconic landmarks. In fact, the luminous form of protest has allowed creative minds to circumvent governmental restrictions like forbidding gatherings of large groups. The smart use of light to enhance protests was already visible in the Occupy Wall Street protest and has been evident in recent demonstrations regarding climate change, Black Lives Matter or the LGBT movement. Artists like Krzystof Wodiczko, Robin Bell, Jenny Holzer, Dustin Klein, The Illuminator collective, Joanie Lemercier and Delight Lab have created projects in the recent years to address the rising social, ecological and political issues in the USA, South America and Europe.

Interesting social media channels of artists and activists:
The success of corporate design guidelines ends with holding on to past values while the environment has changed dramatically. Numerous retail brands de ne not only their furniture and materials but also their lighting. While the standards focus on good visibility, interior designers have recognised that lighting can be a powerful medium to communicate the core brand values. Focal glow, creating brilliance and drama helps to emphasise the exclusive and high-end character of a brand. In contrast, di use brightness of light lines underlines the equality. This warehouse look is typical for low budget supermarkets, where accent lighting could confuse the consumer’s expectation for a bargain.
Software-driven LED media façades provide new capabilities for projecting dynamic visualizations of data onto buildings as an integral part of the architecture and urban appearance. Although this trend with luminous facades including dynamic content is often linked with commercial signage and advertising, it has revived a longstanding critical debate about the roles of architectural ornamentation and iconicism. Yet media façades are becoming more than a canvas for static and repetitive brand displays. Some installations integrate sensors and interfaces to heighten their dynamism and social engagement. Using smart networks, their luminous performances are no longer restricted to a single building, but can include several buildings simultaneously. Furthermore, intelligent networks can link façades around the world. Due to these developments, designers, as well as users, need to gain experience in order to meet the challenges of connected cities, participatory models and visualization techniques. The spread of responsive surfaces will lead to new forms of urban communication. Their design will determine if we will encounter superficial monologues or long lasting memories. The following overview of sensor technology reveals the extent to which media façades react dynamically. In addition, this relatively new technique of visual light communication introduces LED light as a data transmitter.

The column “Light Matters” on ArchDaily explores the development of contemporary light patterns, technologies and visualisation techniques to detect historical influences and to critically discuss the progress of light and architecture. Since 2013 the articles have presented for example masters of light like Tadao Ando, Louis Kahn, Norman Foster or Zaha Hadid. Talking about sustainable approaches regarding daylight, illumination or outdoor lighting are an essential part of the column as well.
ArchDaily has become one of the 1,000 most visited websites on the Internet, according to the latest Alexa Internet ranking in 2020. More than 360,000 users visit the flagship English-speaking platform every day, which when combined with the network of Spanish, Portuguese, and Chinese sites, creates a daily global audience of 650,000 people: the most visited architecture network in the world.
Klaus-Jürgen Maack, former CEO of ERCO, presented an impressive speech for his product designer Alois Dworschak, who retired after having worked for ERCO for more than three decades.
Klaus-Jürgen Maack was born 1938 in Lüdenscheid. He studied as printing engineer in Stuttgart. From 1965 till 2003 he was managing director of ERCO. He introduced ERCO´s maxim “We sell light, not luminaries” and introduced a paradigm shift for the company. His book “ERCO Lichtfabrik” offers a comprehensive overview of his corporate design and product design approach. With his visionary management the company received numerous awards for graphic and product design. He was awarded with the “Bundespreis für Förderer des Designs”. Maack was also chairman of the board of the Design Zentrum Nordrhein Westfalen. Mr Maack started originally an apprenticeship as industrial management assistant in a printing press in Bremen and studied printing in Stuttgart. In 1963, he started to work at ERCO in Lüdenscheid. With leading product designers he introduced innovative luminaire programs. In the mid of the 1970s he initiated the collaboration with the graphic designer Otl Aicher for defining the corporated identity for ERCO as a basis for the visual communication. Projects like the Guggenheim Museum in Bilbao, the Louvre in Paris or the Reichstag in Berlin are illuminated by ERCO.
Germany-based essayists for the SuperLux book, and leading European light artists and lighting industry publishers and advocates, debated recent developments in the smart light cities movement, at an English-language symposium hosted by the Faculty of Architecture at the Technical University of Munich (TUM) in 2016.
On a benign winter’s evening during the city’s Christmas celebrations, the faculty’s Acting Dean, Professor Hannelore Deubzer, welcomed speakers and delegates to its rooftop seminar centre, the Vorholzer Forum, then introduced Dr Thomas Schielke, a SuperLux essayist, light architecture columnist for ArchDaily, and a communications and education leader with ERCO, to conduct the presentations.
SuperLux essayists Schielke, Vesna Petresin, and the book’s editor, Davina Jackson, spoke about recent developments in urban light art. Another essayist, Peter Droege, clarified the beyond-urgent need to power cities only with renewable sources of energy, but noted that lighting amounted to only about two percent of the world’s total energy consumption.
Three decades ago the Hongkong and Shanghai Bank (HSBC) Headquarters by Norman Foster emerged onto the architectural seen as an exemplary product of industrial design. The open layout with its exposed steel structure generated a powerful corporate identity for the bank. But the restrained atmosphere of white architectural lighting and the lack of distinctive façade lighting has lost its attractiveness after sunset. Now the colorful and dynamic relighting presents a remarkable example of how an architectural icon has shifted from a productivist ideology towards a scenographic image.
Bettina Pelz, curator for light festivals, explains the difference in light festivals within Europe and in a global context. She discusses the developments in cities like Sydney, Singapore, Lyon, Eindhoven, Berlin and Lüdenscheid. About Bettina Pelz: Focus of her exhibition practice is light as material and media in contemporary art, integrated design and digital media. Since 1999, and since 2001 partly in cooperation with Tom Groll, she developed various exhibition formats. She lives in the German Ruhr Region.
