Abstract: An aim is to provide a light source device that can be assembled more easily than conventional light source devices. A light source device 100 comprises a light emitting module 150, a mount 140, a lighting unit 110, and a case 120, wherein the lighting unit 110 has a pair of pin terminals 112a and 112b, each of the mount 140 and a substrate 151 of the light emitting module 150 has a pair of through-holes 154a and 154b, and a pair of feed terminals 153a and 153b are disposed at positions of the substrate 151 corresponding to the through-holes 154a and 154b, the pair of pin terminals 112a and 112b being electrically connected to the pair of feed terminals 153a and 153b by penetrating through the through-holes 154a and 154b of the mount 140 and the substrate 151.

Abstract: A light source apparatus that can be assembled and disassembled easily. A light source apparatus 100 includes: a body 120 housing a light-emitting module 110; and a front cover 130 attached to an opening portion 121 of the body 120 and including a light emission window 131 for allowing light emitted from the light-emitting module 110 to go outside. The opening portion 121 is provided on a front side of the body 120. The front cover 130 includes a plurality of engaging claws 134a through 134f and is attached to the body 120 when the engaging claws 134a through 134f engage with a claw receiving portion 124 provided in an outer surface of the body 120.

Abstract: 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.
