ABSTRACT: EDEN PARK ILLUMINATION, INC. and the University of Illinois have formed a team to pursue the demonstration and commercialization of large arrays of microcavity plasmas capable of producing white light panels with luminous efficacies above 30 lumens/W. This proposed project will demonstrate the ability of arrays of microplasmas to yield flat lamps of high efficiency, luminance, and color rendering index suitable for general lighting. Microplasmas represent a new technology that we expect to be disruptive to the lighting industry because their properties (low temperature and atmospheric pressure operation, specific power loadings of kW/cm3) have no parallel in conventional, macroscopic plasmas. A team comprising leading researchers and engineers from the University of Illinois and Eden Park Illumination will aggressively pursue lamps employing molecular emitters of high radiative efficiency to realize lamps having efficacies of at least 30 lumens/W, and luminance values above 500 lumens. A successful program will have a significant impact on the energy consumption of lighting in the U.S. by providing non-toxic, ballast free, lightweight, and efficient lamps with radiating areas > 200 cm2. BENEFIT: General Lighting, Commercial Lighting, Special Lighting

For several, widespread dermatologic disorders such as psoriasis and Bowmans disease, no cure currently exists but the irradiation of the affected tissue at specific wavelengths in the ultraviolet UV) is the only known therapeutic treatment that drives the disorder into remission. Furthermore, currently available treatments based on lasers are expensive and access is severely restricted for the millions of patients in the U.S. alone) who suffer from these diseases. Recently, however, microcavity plasma technology developed at Eden Park Illumination EPI) and the University of Illinois has resulted in flat or curved) lamps that are thin and capable of emitting UV at discrete wavelengths. EPI has, for example, commercialized lamps as large as 5 5 161 cm2) in emitting area that generate more than 10 W of average power at 172 nm. These results are well beyond the performance available in the past from lamps emitting in the deep- ultraviolet, and it appears that this technology can be readily modified to operate at other UV wavelengths. EPI, the University of Illinois, and the Wellman Center for Photomedicine at Massachusetts General Hospital have formed a team to pursue the development, clinical testing, and commercialization of lightweight and compact microplasma lamps that emit at 308 nm. Our focus is providing effective, low cost light sources for the treatment of psoriasis that will allow broader access for patients to treatment at a dramatically reduced cost. Lamps having an emitting area of 4 4 100 cm2) and output of ~20 mW/cm2 will be designed in Phase I of this program and a prototype of the lamp will be constructed. Phase II will focus on the fabrication in a process suitable for mass production), testing, and clinical verification of lamps as large as 12 12.

Eden Park Illumination, Inc. is pursuing the development and commercialization of large arrays of microcavity plasmas capable of generating light in the vacuum ultraviolet and deep ultraviolet wavelength ranges (VUV and UVC espectively), but in a slim and flat form factor. Ultraviolet is well known to be efficient in enabling a number of chemical processes, and is particularly effective for disinfection. The ability of deep UV and VUV radiation to neutralize pathogens (bacteria, viruses, and cysts), drugs (hormone regulators), and organic chemicals of increasing concern in drinking water and water re-use is well-documented. The primary drawbacks of conventional UV light sources, however is their poor form factor and environmental concerns associated with their disposal (because of the use of mercury). Microplasmas are mercury-free, non-equilibrium, low temperature plasma sources and they are characterized by high power loading (several hundreds of 100 kW/cm3) which enables them to excite gases and produce UV- generating excimer molecules efficiently. In addition to their compact (and flat!) form factor, they have other desirable attributes such as instant on-and-off, full dimmability, and low-sensitivity to the ambient temperature, all of which enable them to be efficient in various field applications when compared to their mercury-containing counterparts. In the Phase II program, we have successfully demonstrated flat UV lamps that are scalable (up to 12 12 square inches in surface area at present), flat, and have a slim form factor (total thickness less than ~ 6 mm). Thanks to enhancement of the electric field strength in arrays of microcavities fabricated within the lamp, our lamps reliably produce radiant intensities above 110 mW/cm2, which is the highest value among commercially available lamps at 172 nm. Furthermore, the spatial uniformity of light emission across the lamp is extraordinary (> 90 %). These lamps are currently being evaluated by a number of partners and customers. In parallel with our commercialization efforts, we propose to extend the UV lamp technology to the UVC wavelength range (207, 222 nm and 260 nm, in particular) which currently has the market share in UV industrial and applications. We have already validated the technical feasibility and potential markets for these flat lamps, and it is our intention to develop products and a large-volume manufacturing process to accelerate entry into the marketplace. Ultraviolet light tiles capable of producing tens of mW/cm2 at 207, 222 and 260 nm from various gas emitters and phosphors will be developed, and a product with an active area of 1 square foot at these wavelengths will be commercialized for water treatment and other commercial UV applications (disinfection of surfaces, polymer curing, etc).

EDEN PARK ILLUMINATION, INC. and the University of Illinois have formed a team to pursue the demonstration and commercialization of large arrays of microcavity plasmas capable of producing visible emission with luminous efficacies above 20 lumens/W. Originally developed in the Laboratory for Optical Physics and Engineering at the University of Illinois, microplasma array technology has recently advanced to the point of yielding planar radiators having active areas of at least 100 cm2 and efficacies of ~15 lumens/W. This proposal describes a nine-month, Phase I program designed to increase the efficacy of these arrays by a minimum of 33%, to beyond 20 lumens/W. The focus of this program is the Al/Al2O3 microplasma device structure developed at Illinois with which we are now able to control precisely the shape of the microcavity walls, thereby opening the door to optimizing both the electric field within each microcavity as well as the efficiency for extracting photons from the device. Furthermore, a design for fully addressable arrays will be developed in Phase I. BENEFIT: This STTR program will yield visible and ultraviolet (UV)-emitting arrays that are extremely lightweight (being made literally from Al foil), thin (< 1.5 mm in thickness) and having a form factor and efficiency superior to those for incandescent lighting. This technology will provide mercury-free lighting for DOD and the commercial sector that is inexpensive and, when sealed between thin plastic sheets, flexible. Aside from its impact on lighting, this technology will be of enormous value to: 1) medicine by providing flexible light sources ideally-suited for phototherapeutics, 2) the sterilization of operating environments, and 3) water and air purification.
