Abstract

PURPOSE: To prevent the shading of light by the bimetal conductor by providing the bimetal to the lamp so that the tip of bimetal is bent to contact with the luminous tube when lighted out and the bimetal is deformed along the inner conductor when lighted.
CONSTITUTION: The bimetal conductors 16, 17 are provided so that these are parallel to the inner conductors 10, 11, the tip of bimetal is bent to contact with the luminous tube 3 when lighted out, it is deformed to be approximately parallel to the inner conductor and the minimum distance between the bimetal and the luminous tube is made 5 mm or more when lighted. By this way, light is not shielded by the bimetal conductor, no crack is produced in the luminous tube made of clear ceramic because the minimum distance is made 5 mm or more when lighted.
