Abstract

PURPOSE:To prevent the non-uniform density of a fluorescent lamp tube for exposure which takes place at the time of controlling an electric power thereto by detecting the temperature of the tube wall of the fluorescent lamp so as to control an amt. of blowing, and maintaining the temperature of the tube wall which exhibits the max. light emission efficiency o f the fluorescent lamp.
