Advanced LED Downlights
LEDs have improved rapidly in both luminous efficacy and color quality.
LED’s small form factor make them a good candidate for downlight applications but the high brightness LED products can cause visual discomfort and the constricted thermal environment in downlights can be extremely challenging for LEDs.
The California Lighting Technology Center (CLTC) at the University of California, Davis is developing a downlighting system based on indirect optical designs that will reduce direct LED glare, decrease installation time and improve thermal management. Collaborators include Architectural Energy Corporation (AEC), California Lighting Technology Center, Capri, and Samsung.
Features and benefits include a single central power supply that is utilized for cost savings and energy efficiency. Low Voltage (class 2) wiring between the centralized power supply and the downlights to allow for
easier wiring which allows for easier and cheaper installations. Indirect Optics increase visual
comfort and produces a downlight with uniform brightness. Better Thermal Management from the Indirect Optic places the LED sources in a location where they can be more easily thermally managed, which improves LED output and life. And central power supply architecture allows for easy espandability for additional downlights as well as other LED fixtures such as under cabinet fixtures.
Applicatons for advanced LED downlights include most living and working areas such as residential kitchens and hallways; commercial corridors, conference rooms and breakrooms; and hospitality locations such as restaurants, corridors and lobbies.
This commercialization research project is part of the latest PIER portfolio—Lighting California’s Future (LCF).
