A lamp system () includes a straight tube type lamp () and a socket (). The straight tube type lamp () includes a straight tube type cover () containing a light-emitting element, and caps () arranged at both ends of the cover (). A pair of lamp pins () whose tips respectively protrude in directions intersecting a lamp longitudinal direction are protrudingly provided on end faces of the caps () at both the ends. The socket () includes a socket body (), a rotor () which is arranged in the socket body () and on which the pair of lamp pins () of the straight tube type lamp () are mounted, and a pair of terminals to which the pair of lamp pins () mounted on the rotor () are connected. At least the rotor () can move in the lamp longitudinal direction.

Lamp system

Discoloration and deformation of a resin case triggered by heat generation from a failed circuit component at the end of the life of an arc tube are prevented without increasing the cost and size. A lighting unit that lights a light source with an inverter while receiving electric power from an AC power supply, and that contains a lighting circuit that includes a plurality of circuit components inclusive of capacitors. Among the capacitors, all capacitors with an applied voltage of 50V or greater (C, C, C, C, C, CDand CD) are foil type film capacitors with exceptions of smoothing electrolytic capacitors (CDand CD).
