Forces of Change | 3D Printed Lighting Nov 05, 2018

As if our lighting community needs more disruption, we are poised for a radical change in how we make, distribute and sell our products. We have experienced two digital revolutions already in communication and computation. We can communicate instantly across the globe at no charge and computers are integrated into our lives. Digital fabrication is the third digital revolution. When we can make our own lighting sources, heat sinks, optics and luminaires in our garage or locally at a store with a larger 3D printer (3D Kinkos?) then business as usual is over. Container loads from Asia, our sales and distribution network and other peripheral support processes cease when costs equalize though local 3D printing. This will happen incrementally at first then accelerate to exponential growth as we experienced with communication and computation. The revolution has already begun with choices of 3D printers available on Amazon Prime for under $200. The Lighting Research Center has expanded their LED Lighting Institute to include content on 3D printing. Nadarajah Narendran, Ph.D. is the Director of Research at the LRC and is the Professor teaching a hands-on 3D lighting class. He has been leading a team that conducts research and educational programs to accelerate the development and market transformation of lighting technologies. The seminar culminates with participants designing, building and evaluating their own lighting fixtures including custom 3D printed components. Please enjoy this conversation between Narendran and host Mark Lien on this timely issue impacting in our lighting community.

FIRES | Melanopic Green The Other Side of Blue Aug 21, 2018

Numerous medical studies have shown that exposure to blue light at night suppresses the production of melatonin by the pineal gland in our brains and so disrupts our circadian rhythms. As a result, we may have difficulty sleeping. It is therefore only common sense that we should specify warm white (3000 K) light sources wherever possible, especially for street lighting.

True or false?

Forces of Change | 90.1 Modeling Apr 25, 2018

This podcast features two key members of the ANSI/ASHRAE/IES 90.1 Lighting Subcommittee that establishes lighting power density levels for this foundational standard. The discussion reveals and explains to our lighting community a new project that is funded by ASHRAE, IALD, BC Hydro and the IES. Project tasks will support the work of the 90.1 standard by providing AGI32 modeling runs by application. These models will improve the accuracy of and strengthen the effectiveness of this and the other standards affected by 90.1. It is a concern especially because LED luminaires are now being used as the primary baseline to establish LPD’s instead of traditional sources. This has resulted in significant energy savings but there is an end game. The partners want to verify that the quality of lighting is not impacted in future versions of 90.1 and the other standards that reference it.

FIRES | The Science of Near-Infrared Lighting: Fact or Fiction Mar 29, 2018

There is a common-sense argument being presented in the popular media that since humans evolved under sunlight, our bodies must surely make use of all the solar energy available to us. Given that more than 50 percent of this energy is due to near-infrared radiation, we are clearly risking our health and well-being by using LED lighting that emits no near-infrared radiation whatsoever.

Forces of Change | Lighting as a Service Mar 20, 2018

Discussions about Lighting as a Service (LaaS) are no longer focused on whether it will evolve into an essential aspect of future lighting projects, but rather on how many billions of dollars will be involved and how soon it will become a common offering.
