Lighting device |
摘要 |
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. |

1. A lighting device, comprising:
a device body attached to an installation surface: one or more surface light-emitting modules held in the device body; and a cover attached to the device body in an opposing relationship with a light-emitting surface of each of the one or more surface light-emitting modules, wherein each of the one or more 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, and at least portions of the cover facing light-emitting surfaces of the one or more surface light-emitting modules are made of a light-transmitting material, the cover being attached to the device body by a force stronger than the elastic force wherein the device body includes a frame portion, the frame portion having an L-shaped cross-sectional shape formed along the entire circumference of an end portion of the device body, and wherein the cover is attached to the device body in a spaced-apart relationship with the device body and the light-emitting surfaces such that a portion of the light emitted from the one or more surface light-emitting modules is repeatedly reflected between the cover and the light-emitting surfaces. |
