Abstract: A lighting device includes a device body attached to an installation surface, one or more surface light-emitting modules held in the device body, and a cover held in the device body in an opposing relationship with light-emitting surfaces of the surface light-emitting modules. Each of the surface light-emitting modules includes a light-emitting unit having a light-emitting body and a base unit fixed to the device body and configured to removably hold the light-emitting unit by an elastic force. At least portions of the cover facing the light-emitting surfaces of the surface light-emitting modules are made of a light-transmitting material. The cover is held in the device body by a force stronger than the elastic force.

Abstract: A lighting device includes a device body adapted to be installed on a surface of a room and first organic electroluminescence element modules including organic electroluminescence elements, the first electroluminescence element modules being held in the device body with light-emitting surfaces of the electroluminescence elements facing toward the surface of the room when the device body is installed on the surface of the room. The lighting device further includes a light-transmitting protection cover configured to cover the light-emitting surfaces of the first organic electroluminescence element modules.
