MERCURY-FREE HIGH CRI EFFICIENT LAMP

FUSION SYSTEMS HAS DEVELOPED A MERCURY-FREE, HIGH COLOR RENDERING, EFFICIENT LAMP USING PROPRIETARY BUT BENIGN LAMP FILLS. THEY PROPOSE TO INVESTIGATE VARIATIONS OF THE LAMP SYSTEM PARAMETERS WITH THE DUAL GIALS OF FURTHER INCREASING SYSTEM EFFICIENCY BY 1.5 X AND TO IMPROVE LAMP STARTING DOWN TO MINUS 40C. BOTH FACTORS ARE CRITICAL TOWARD ACHIEVING COMMERCIAL SUCCESS. THE NEW LAMP IS A MICROWAVE POWERED, BRIGHT, LONG LIVED, STABLE, 6,700K LIGHT SOURCE WITH A CONTINUOUS VISIBLE SPECTRUM YIELDING A COMMISSION INTERNATIONALE DE L'ECLAIRAGE (CIE) RA COLOR RENDERING INDEX OF 85. ITS SMALL SIZE AND SPHERICAL SHAPE PROVIDE EASE OF OPTICAL CONTROL USEFUL IN LUMINAIRE DESIGN. IR AND UV RADIATED OUTPUT ARE LESS THAN MOST OTHER DISCHARGE LAMPS. FUSION SYSTEMS WILL PERFORM ENERGY BALANCES FOR VARIOUS BENIGN LAMP FILLS, BULB COATING, COOLING AND POWER INPUT. IN AN ITERATIVE PROCESS, THEY WILL USE THESE MEASUREMENTS TO FORMULATE PREDICTIVE STATISTICAL LAMP MODELS AND DERIVE IMPROVED LAMP COMFIGURATIONS. AT THE SAME TIME, THEY WILL EXAMINE POSSIBLE LAMP STARTING SCHEMES USING VARIATIONS IN LAMP FILL, INITIAL ELECTRICAL CONDITIONS, AND EXTERNAL STARTING RADIATION.
