In California, 90% of ceiling fans sold have light kits with incandescent sources and an average connected load of 120 watts.
Recent Title 24 changes marginally increase energy savings in these applications via dimmers but significant energy savings potential remains by shifting the fan lighting market towards energy efficient sources.
The California Lighting Technology Center (CLTC) at the University of California, Davis and Hunter Fans have partnered to design and develop a ceiling fan system that optimizes a combination of emerging LED technology and commerciallyavailable lighting controls to create a cost-effective LED lighting kit for energy savings.
The LED ceiling fan light kit will serve as a direct bolt-on replacement for pre-existing fan systems providing a smart energy-efficient retrofit solution. The retrofit fan light kit will be comprised of an LED array, power supply, glass dome with a hanging tree, and a mounting plate.
- The LED light kit will be designed to have an output of 32 Lumens per watt (approximately 800 lumens at 25 watts). Typical incandescent kit systems usually produce less than 15 lm/W.
- Custom low profile LED driver developed by Hunter Fans and Texas Instruments.
- Pull Chain Switch allows for dimming, ON and OFF functions of the LED luminaire.
The project on LED Residential Fans seeks to develop and commercialize novel LED-based lighting kits for ceiling and exhaust fans in residential applications. Both retrofit and new construction residential applications are indicated with possible opportunities in commercial applications. Additionally, the project will explore the integration of controls systems to the LED fan systems to determine if additional energy savings can be achieved in a cost-effective manner.
The CLTC and Hunter Fan are project partners. This project is part of the latest PIER portfolio — Lighting California’s Future (LCF). LCF program information and reports: www.archenergy.com/lcf/LED-projects/ceilingfan.html
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.

The project on Integration of Electric Lighting Controls with Utility DR Signals seeks to
identify the most cost-effective and reliable combinations of utility
DR signals and electric lighting controls to implement automated DR
capabilities with bi-directional communication capabilities that will
allow utilities to get feedback on achieved lighting load reductions.
The project will focus on lighting loads and be applicable to all
buildings without need for Internet access and energy management
systems. The solution includes communication/control from utility to building and from building to fixture.
Key project partners are the CLTC and SCE.
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.

The purpose of the Lighting California's Future "Market Connection" effort is to shape
and support technology development and early deployment efforts in
order to accelerate the technology diffusion process and help meet codes and standards including Title 24, IESNA, ASHRAE, and LEED.
The ultimate outcome of the market connections element is broad market adoption of the lighting products developed within the LCF program, including codes and standards covering qualified products. As technical projects become available for initial field pilots, team members will develop and provide project specific information to California utility emerging technology programs and the University of California/California State University Energy Efficiency Partnership Program, and other similar groups.

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).
Cost-Effective Demand Response (CEDR) research by Lighting California's Future seeks to introduce a novel demand response (DR) lighting control technology that can be easily retrofit to existing buildings.
CEDR makes retrofit installation economical by using existing power wiring to transmit a load shed signal to designated lighting loads. This signal, introduced at the lighting panel and transmitted to receivers installed in existing bi-level light switches, tells receivers to turn off half the lights.
This research project will develop a new system capable of receiving a utility demand reduction signal and transmitting, over the building power lines, a load-shed signal to multiple receiver devices. The outcome of the project is the development and commercialization of a novel demand responsive lighting technology.
CEDR takes a low-tech approach, doing only one simple task inexpensively - reducing loads during DR conditions.
Applications
■ Buildings with lighting controlled by bi-level switching.
■ Buildings with significant sheddable plug loads.
■ ESCOs with the above customers.
■ Utilities requiring more automatic DR capacity.
Key project members are the CLTC, NEV Electronics, and SCE. Collaborators include NEV Electronics, Benya Lighting, California Lighting Technology Center (CLTC), Southern California Edison, and Architectural Energy Corporation.
