SHORT-LENGTH LOW-PRESSURE DISCHARGE LAMP ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To reduce the whole height of a low pressure discharge lamp such as a compact fluorescent lamp. SOLUTION: Both end parts 22 and 24 of an envelope are turned inside in the radial direction to be connected to a base part. Therefore, an advantage such as an electrode housed in the envelope is positioned in a place separate from the base part is obtained. Resistance to escaping force is also obtained by this installing structure, and cement to fix the envelope to the base part is omitted, and an advantage such as heat transfer is improved is obtained.
