Lighting California's Future's project on Improved Daylight Performance of Tubular Daylighting Devices (TDDs) is developing, demonstrating, and helping commercialize new diffuser elements that redirect a significant portion of the emitted daylight towards the ceiling and precisely filter and spread the rest, producing a direct/indirect luminaire effect. The result will be to increase the acceptance of TDD daylighting systems by introducing systems with luminance ratios that are closer to the accepted norms for interior spaces.
The project accelerates the development & release of new TDD diffuser options that address market barriers to daylight usage. Options include reducing direct glare from diffuser surfaces and increasing ceiling illumination. The goal of the research is to provide off-the-shelf daylighting solutions which support current visual comfort trends in commercial spaces.
Measurement and simulation of daylighting performance of standard TDDs included photopia models and ray trace analyses, as well as HDR verification of simulations.
Project partners are CLTC, SCE and Solatube International, Inc.
LCF Research will continue through 2009.

More information from Lighting California's Future"decorative fixtures must be more than pretty objects; they must also deliver the light that is needed in a space, to the surfaces that need it, and now they must do it with a minimum of watts. If you are designing a space with a contemporary, futuristic, or jazzy feel, it's not that big a deal because many manufacturers make some acceptable attractive fixtures in compact fluorescent, LED, or (rarely) in metal halide.

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).
