LIGHTING BODY, FILM DEPOSITION METHOD AND FILM DEPOSITION APPARATUS IN LIGHTING BODY

摘要

When a reflective film is formed on the inner side face of a housing and at the distal end of a light source while incorporating the light source in the housing, film thickness at the distal end of the light source is made thicker than that on the inner side face of the housing. A first die (6) becoming a fixed die is provided with first and second film deposition apparatus (9, 10) equipped with first and second magnetron sputtering systems (9a, 10a), and a masking member (16) is provided at the opening of a target chamber (11a) constituting the first film deposition apparatus (9). Following to a primary injection step, a first film deposition step by the first film deposition apparatus (9) and a second film deposition step by the second film deposition apparatus (10) are performed for the housing (4) held on a second die (6) while incorporating a bulb (3).
