Abstract
A lamp including a light source (30) housed within a reflector (10), the reflector further includes a coating (24) over a major portion of an inner (20) and/or outer surface (22). The coating (24) is comprised of multiple layers of high and low index of refraction materials to provide at least 90% reflectance between about 425 and 750 nanometers and less than 20% reflectance peaks between about 900 nanometers and 1800 nanometers
