More Information
Summary:Ceramic HID lamps with improved thermal management having an adherent infrared reflective coating layer located on the outer surface of the vessel are described. They include a coating of a nonmetallic material proximate the first and second end portions of the vessel. Such coatings can minimize temperature gradients during lamp operation. Methods for preparing such lamps with improved thermal management are described as well.
