Enriching Horticultural Lighting for Faster Growth and Better Crops

Enriching Horticultural Lighting for Faster Growth and Better Crops

Horticulture lighting is no new lighting application, but it gained momentum with the introduction and evolution of LED lighting, and it is meanwhile one of the fastest growing markets in lighting. Dr. Richard Blakey, Application Engineer at Würth Elektronik eiSos, explains how LED-based horticultural lighting can deliver even bigger advantages for commercial growers by introducing additional wavelengths that increase photosynthetic response - like Würth Elektronik's new members of the WL-SMDC SMD Mono-Color Ceramic LED Waterclear family that is used as a reference in the article.

48 VDC Integrated Drivers Offer New Options

48 VDC Integrated Drivers Offer New Options

LpR 70 Article, page 102: In the telecommunication and IT businesses, especially, 48 VDC grids have become quite popular. This growing global trend to facilitate direct current (DC) power supply in building "microgrids" presents new opportunities for solid state lighting designers. TE's Lighting Industry Manager, Ron Weber, and Global Product Manager, Scott Hamilton, describe how LED lighting fixture designers can now design luminaires around a 48 VDC constant voltage input, available to take advantage of the benefits of a low voltage DC distribution grid in a building.

WHITE PAPER - The Calibration Traceability Chain of a Photometric LED Test System

WHITE PAPER - The Calibration Traceability Chain of a Photometric LED Test System

FluxGage is a LED luminaire tester and provides a small and cost-effective solution for testing LED luminaires in 2π geometry. The black measurement surface and the lack of multiple reflections make the system much more predictable and allow using information about the DUT such as size, beam angle and surface reflectivity, to calculate correction factors.

New LRC Study Tests the Impact of Circadian Light on Alertness in Office Workers

New LRC Study Tests the Impact of Circadian Light on Alertness in Office Workers

In 2017 the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute published a groundbreaking study showing that office workers who receive a robust dose of circadian-effective light experience better sleep, and lower levels of depression and stress, than those who spend their days in dim or low light levels. The team of LRC researchers, led by Dr. Mariana Figueiro and sponsored by the U.S. General Services Administration, measured existing light levels for 109 participants at five federal office buildings designed to maximize daylight availability indoors. The research team found that even in open offices with many, large windows, office workers were not receiving enough light to stimulate their circadian system during the day, due to factors such as season, cloud cover, desk orientation, and window shade position.
