The All Things Lighting Association (ATLA) was recently announced by founder Ian Ashdown, P. Eng. (Ret.), FIES — a longtime member of several established industry associations, lighting scientist, and president of software development firm SunTracker Technologies. ATLA’s mission, according to its inaugural release, is “to advance, support, promote, and contribute to innovation, science, and engineering in all fields of lighting, including architecture, health, horticulture, and entertainment.”
LEDs Magazine reached out to Ashdown (who has served as Strategies in Light advisory board member, LEDs Magazine Sapphire Awards judge, and editorial contributor) for elaboration on the launch and the role of ATLA in the academic and design community.
Ashdown explained that in conjunction with international contributors, ATLA has developed two standards for the international lighting community. “The first reason [for launching a new association] is to provide ATLA S001, Standard Format for the Electronic Transfer of Luminaire Optical Data, and ATLA S001-A, Amendment to Standard Format for the Electronic Transfer of Luminaire Optical Data, Including JSON Specification, as freely-available standards for lighting industry adoption,” said Ashdown via email. “ATLA S001 has been adopted as ANSI/IES TM-33-18 and (in Italian) UNI 11733:2019, while ATLA S001-A is currently under consideration by CIE Technical Committee 2-92.* If approved, ATLA S001-A will likely become a joint CIE/ISO standard. It is also under consideration by the IES as a successor to TM-33-18.”
According to the current ATLA S001 documentation, existing standards for electronic transmission of far-field photometric data and other information do not account for spectral power distribution (SPD) or radiant intensity distributions and photosynthetically active radiation (PAR) used in horticultural or animal-centric applications such as aquaculture and animal husbandry. ATLA 2001 is intended to provide a standardized format for all types of luminaire optical test data that can be conveyed in an XML Schema so the data can then be analyzed across multiple types of design, visualization, and simulation software tools used by lighting and architecture professionals. ATLA-S001A amends the 2018 ATLA 2001 to include JSON format guidance that can reduce the complexity of XML documentation.
When asked about affiliations, Ashdown indicated that “at present, ATLA has no formal relationship with ANSI, ASABE, CIE, IES, ISO or other standards organizations.” As a secondary objective, he expects ATLA to continue growing a knowledge base of lighting issues and projects; provide an opportunity for graduate student mentorship and funding; and facilitate academic and industry collaboration.
“The goal of ATLA is to encourage and support its members in thinking of lighting research and design not as ‘illumination engineering,’ but as a cross-disciplinary topic rich in opportunities for both researchers and companies,” said Ashdown.
Cross-disciplinary research and commercial development have supplied the backbone of multiple academic centers and laboratories involved in advancing solid-state lighting (SSL) and lighting design best practices.
For example, the New York State Energy Research and Development Authority (NYSERDA) established the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute (RPI), which has since split into separate organizations supported by RPI and the Mount Sinai healthcare organization. LRC had expanded its studies of lighting applications and technology into a continuing education program, collaboration on standards development, and work with commercial partners on 3-D printing for LED lighting.
RPI’s Lighting Enabled Systems and Applications (LESA) Center laboratory and Center for Architecture Science and Ecology (CASE) leadership has also partnered to incubate technologies that will enable net-zero buildings and climate resilience through architectural design and applied engineering in its Institute for Energy, the Built Environment, and Smart Systems (EBESS).
Both examples are aligned with a specific academic institution, of course. Ashdown’s hope for ATLA is to encourage open participation and contributions “from the community at large” within the scope of an online platform.
