摘要 |
A curved lamp manufacturing method including a curving process in which a straight glass tube sealed with reduced pressure inside is heated and curved. The curving process includes: a first step of holding a predetermined portion of the glass tube using a first chuck, and holding one end portion of the glass tube using a second chuck such that the second chuck can slide in a longitudinal direction of the glass tube; and a second step of, while heating a planned curved portion of the glass tube positioned between the predetermined portion and the end portion by a heater, curving the planned curved portion by moving the second chuck relative to the glass tube. The end portion is moved in the second step so that a weight of the end portion is applied to the planned curved portion that has been softened by the heater.
