Discomfort Caused by Glare from Luminaires with a Non-Uniform Source Luminance
Discomfort Caused by Glare from Luminaires with a Non-Uniform Source Luminance Glare and the resulting discomfort are a persistent issue in lighting that became even bigger with the introduction with LEDs as a light source. While the UGR method is well established, it is sometimes heavily discussed if it is appropriate for SSL. The limitations of the UGR method need to be understood. Peter Thorns BSc(Hons), CEng, FCIBSE, FSLL, explains these limitations and consequently describes the research and how to apply correction measures. Read more »

Adopting an LED More Suited to Circadian Entrainment
Adopting an LED More Suited to Circadian Entrainment Since the introduction of LED lights, a lot has been said about risks of blue light for ocular health on the one hand, and the opportunity of circadian entrainment, on the other hand. While a controversial discussion on the first topic is ongoing, the second topic is well accepted. To solve both issues, Bill Chan, President of LiteController Inc. proposes the application of 465-470nm pumped phosphor converted white LEDs with a content of 86% - 92% blue-turquoise light and 8% - 14% blue-violet light. In the article he concentrates on the second topic and proves the benefit of regulating the circadian entrainment more efficiently, maintaining a high typical efficacy of 150 lm/W and good color rendering of CRI 80+ ideally supporting the WELL Building Standard.

LUXEON 3030 HE Plus Deep Dimming: Uniform Dimming To 1%
LUXEON 3030 HE Plus Deep Dimming: Uniform Dimming To 1% Lumileds introduced the first LED engineered for architectural applications that require uniform light output through the entire dimming range and operating conditions. The new LUXEON 3030 HE Plus Deep Dimming mid-power LED is designed for LED to LED flux uniformity across the entire dimming curve – down to 1% - that is required to achieve consistent visual performance. From full intensity above nominal current of 65 mA to 1% intensity at 0.65 mA, every LED will provide the same flux performance in the application. Key to the performance is forward voltage variance of just 0.10 V which simplifies driver design and compatibility. The single 3 SDCM color bin ensures color consistency at any CCT. Lumileds 3 V 3030 package is a proven, high efficacy industry standard platform that allows for drop in replacement of existing 3030 footprint LEDs. Read more »
