The most interesting technology that I saw at LEDucation, last week, was the Airelight LED ceramic luminaires from GoldenEye Lighting. They’re a California-based manufacturer with a novel light source platform. Their luminaires reflect white LEDs within a ¼”-thick aluminum channel that serves as a diffusing chamber. The light emits through a diffuser that is alumina, [...]

2023 is generally looking to be a good year for commercial lighting rebates, according to BrightSwitch. Here are the top trends that they see for 2023: Over 3/4 of the US has a commercial lighting rebate program. No dramatic change here. The most dramatic change is for rebates on general service lamps, such as A-19 [...]

A.C. Lighting, Inc., an entertainment lighting value-added distributor, recently published an article about immersive color in houses of worship. Historically, houses of worship have used stained glass to wash a nave, sanctuary, or chapel with colorful light and to tell religious stories at the same time. Today, contemporary churches are accomplishing this with color-changing LED [...]

Scandinavian countries have greater acceptance of circadian light therapy for psychological disorders. A hospital in Norway, Valen Hospital, has incorporated circadian light therapy into the emergency treatment of bipolar patients with positive results. Chromaviso is a Danish manufacturer of circadian lighting and light therapy luminaires. The Valen Hospital results have been peer-reviewed and published in [...]

  There is a growing list of sustainability labels and certifications to be aware of. Some are for products, some for buildings, and some for business operations.

  An area of growing research and practice is using lighting to help control agricultural pests. This can include horticultural lighting in indoor growing facilities (aka controlled environment agriculture or CEA) or nighttime treatment with specific wavelengths on outdoor crops. Greenhouse growers have long known that introducing supplemental grow lights to greenhouses can dramatically change [...]

New research from the University of Zaragoza in Spain quantifies how the aging eye restricts the amount of circadian light reaching the retina based on photopic illuminance reaching the corneal plane and considering the optical density of an aging crystalline lens. As the researchers state: “As a result of the described behavior, retinal illuminance may [...]

A Belgian thermal management company named Diabatix nv is offering custom-designed heat sinks that use artificial intelligence/machine learning (AI/ML) generative design to create computer-generated shapes that can be optimized to achieve different engineering goals. Generative design is a process that uses algorithms and machine learning techniques to create and optimize designs based on specified design [...]
