摘要： According to one embodiment, a lighting device includes a radiation surface, at least one light source provided to face the radiation surface, and an optical control member provided between the radiation surface and the light source and includes optical characteristics of transmission, diffraction, diffusion, and reflection, which vary for regions in the optical control member, a distribution of each of the optical characteristics being determined by positions relative to the at least one light source. The optical control member is formed in a sheet shape which is controlled by at least one of a reflective film having a reflection factor distribution, and a reflective film having a numerical aperture distribution, and lenses.

摘要： According to one embodiment, a lighting device includes a light source, and a semi-transmissive reflection layer opposing the light source. The semi-transmissive reflection layer includes a pattern including transmitting portions or reflecting portions. The pattern includes a pattern formed of the transmitting portions each having a hole conformation in a region to which a high volume of light form the light source incident, and a pattern formed of the reflection portions each having a dot conformation in a region to which a low volume of light form the light source incident.

摘要： According to one embodiment, an lighting apparatus includes a base member, a light source configured to emit visible light, and a translucent cover including a translucent region which covers at least a front surface of the light source and emits the light emitted from the light source to the outside. The light source is provided on a front surface flat section of the base member, a luminous intensity of the light emitted from the light source has a directionality which is strong in a normal direction of the front surface flat section and becomes zero on a rear surface side. The translucent cover includes a domed shape having a maximum diameter at a position higher than a height of the position where the light source is arranged, and a transmittance of a region opposing the light source is 60% or less.
