摘要： According to one embodiment, a lighting device includes a light source with a directivity and a light-transmitting cover including a light-transmitting area configured to emit light from the light source to the outside. The light-transmitting cover is in a dome shape and formed of a material doped with scattered fillers dispersed in a volume thereof. The light-transmitting cover includes a vertically elongated shape with an aspect ratio higher than 0.6, and having a transmittance of 70% or less. The aspect ratio is the quotient of a height of the light-transmitting area in an optical axis thereof divided by the width of a rear-end portion of the light-transmitting area.

摘要： According to one embodiment, a lightning device includes a base member, a light source on the base member, a light guide body configured to guide at least part of light forwardly emitted from the light source. The light guide body includes an incident portion covering the front of at least the part of the light source, a bent light guide portion outwardly bent from the incident portion and configured to curvedly guide incident main light to the outside, and a light-emitting surface located on the distal end of the bent light guide portion, directly exposed to the outside of the device, and configured to emit the curvedly guided light laterally or rearwardly relative to the light source.

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.

摘要： According to one embodiment, a lighting device includes a light source, and at least one light distribution control member configured to control distribution of light from the light source. The light distribution control member includes a base member higher in refractive index than air, and two optical control layers located opposite each other with a predetermined space therebetween on either side of the base member. The two optical control layers each includes a first region and a second region formed in correlative patterns. The light distribution control member is configured to control the light distribution based on a change of an overlap between the first and second regions depending on a direction of transmitted light.
