Lighting device

摘要

According to one embodiment, a lighting device includes a base member, a light source on the base member, a light-transmitting cover configured to cover the light source and to emit light emitted from the light source to the outside, and a light guide body provided opposite the light source and configured to guide, to the rear of the light source, at least part of the light from the light source. The cover includes a back light-transmitting region having a plane-normal line directed rearwardly. The light guide body includes a light-incident portion facing the light source and a light guide-emitting portion curvedly extending outward from the light-incident portion, having a distal end portion extending along the back light-transmitting region and directed to the rear.

主权项

1. A lighting device comprising: a base member, a light source disposed on a front portion of the base member, a light-transmitting cover attached to the base member so as to cover the light source and configured to emit light emitted from the light source to the outside, and a light guide body provided opposite the light source and configured to guide, to the rear relative to the light source, at least part of the light emitted in a forward direction from the light source,
wherein the luminous intensity of the light emitted from the light source has strong forward directivity in the normal direction of the front of the base member, the light-transmitting cover comprises a back light-transmitting region having a plane-normal line directed rearwardly relative to the lighting device, the light guide body comprises a light-incident portion facing the front of the light source and a light guide-emitting portion curvedly extending outward from the light-incident portion, comprising a distal end portion extending along the back light-transmitting region and directed to the rear relative to the light source, and configured to guide and emit light incident on the light-incident portion through the distal end portion.
