Evaluate feasibility of exterior barrier coatings on remote source HID lamps. Coat lamps with prelimiary designs and measure thermal distributions. Detail likely design space (materials, coating methods, annealing methods) for large-scale success. In Phase II, develop detailed designs, coating process, annealing process and tooling design. Determine effect of using evenly applied coatings (low pressure chemical vapor deposition) vs. uneven coatings applied by line-of-sight coating methods. Produce prototypes. Publish life and photometry effects of these coatings.
