MICROWAVE-EXCITED ELECTRODELESS DISCHARGE BULB AND MICROWAVE-EXCITED DISCHARGE LAMP SYSTEM

摘要

Microwave enhanced induction discharge bulbs here and has high luminous efficiency lamp system that uses a light bulb is designed to generate a substantially white light . The bulb is a rare earth element halides , sodium halides , mercury , and rare surrounds the enclosure containing a mixture of gases . The rare earth element halides is at least one halide selected from the group consisting of cerium and praseodymium halides . By including cerium halide and / or praseodymium halide and mercury Co , the bulb can cause almost white light with excellent luminous efficiency of a microwave when activated .
