todd bracher + 3M feature virtual LED technology with 'lightfalls' architectural lighting
New York designer Todd Bracher, in collaboration with 3M architectural markets, has developed 'Lightfalls,' an innovative architectural lighting system that incorporates 'virtual LED' technology. This experimental modular system, showcased during New York Design Week 2012 at WantedDesign, aims to significantly reduce energy consumption by leveraging advanced optical principles rather than relying on a multitude of LED bulbs. The core concept behind 'Lightfalls' is the efficient distribution of light from a minimal number of actual LED sources across a large surface area, creating the illusion of numerous light points.
The 'virtual LED' technology employed in 'Lightfalls' primarily utilizes only 12 LED bulbs to illuminate an expansive wall. The majority of the light observed is not directly emitted from additional LEDs but is generated through the strategic reflection of the initial 12 bulbs' luminosity. This is achieved by incorporating highly reflective proprietary 3M film, which boasts a 98% reflectivity rate. This film effectively channels and disperses the light from a single LED source across various modules within the system. The result is an architectural lighting solution that provides ample illumination while dramatically cutting down on energy usage.
The system's effectiveness stems from its ability to exploit the laws of physics. By carefully positioning a single LED amongst an arrangement of reflectors, the light is steered and distributed to fill the space, creating a perceived array of multiple light sources. This intelligent design allows for the creation of various lighting formations, whether circular or linear, all while maintaining a consistent and widespread flood of light. The visual effect gives the impression of a complex and dense lighting installation, when in reality, it is a streamlined and energy-efficient setup.
Todd Bracher emphasizes the synergy between physics and design in the creation of 'Lightfalls.' He expressed his fascination with 3M's applied sciences and highlighted that such innovative concepts are only attainable through collaborative efforts with companies possessing 3M's technical prowess, engineering skills, and material expertise. Bracher views design as being fundamentally driven by reason and function, and his partnership with 3M exemplified this philosophy. He underscored the importance of such collaborations within the industry to foster continued evolution in both commercial viability and ideological advancements in design. The installation served as a testament to the potential for ecological and economical lighting solutions in contemporary architectural design.
