ATTACHMENT STRUCTURE OF LIGHTING DEVICE

摘要

In disclosed attachment structure of a lighting device, an elongated lighting device is incorporated between adjacent ceiling members. The lighting device is provided with: a light source; a light-guide member that guides light emitted from the light source to below the ceiling; and an elongated case body that houses the light source and the light-guide member. The light-guide member has: a light entrance surface that is elongated and that is at one end surface in the lengthwise direction; and a light-emitting surface that radiates illuminating light at one side surface in the lengthwise direction. The light source is provided facing the entrance surface of the light-guide member. Adjacent ceiling members are provided with a first and second holding piece that each protrude towards the rear of the ceiling from a pair of side edges that face each other. The lighting device is held in a manner so as not to protrude from the ceiling surface between the first and second holding pieces that face each other of adjacent ceiling members, and is attached to adjacent ceiling members by means of an anchor that successively penetrates the first holding piece, the case body, and the second holding piece in the given order at a position that is at least above the light-guide member.
