Long Lifetime HID Lamps for Remote Source Lighting

In this SBIR Phase I effort, Structured Materials Industries, Inc., www.structuredmaterials.com (SMI) will develop long-lifetime, low-wattage High Intensity Discharge (HID) lamps, for remote source lighting applications. Remote source lighting systems have the potential for improved operating and maintenance costs, as well as greater safety in wet environments and near flammables or explosives. SMI will develop and demonstrate optical coatings for low-wattage, high brightness HID lamps, based on SMI's well established technology for chemical vapor deposition. In Phase I, we will demonstrate high performance optical coatings on both test substrates and on actual low-wattage HID lamp envelops. We will fabricate low-wattage HID lamps with the coated envelops, and demonstrate improved performance, including better temperature uniformity of the lamp envelop and overall increased lamp lifetime. We will also develop a plan to integrate the optical coating technology into commercial production of long lifetime, low-wattage HID lamps, specifically optimized for remote source lighting applications.
