Lighting apparatus
A lighting apparatus is held by a chassis and includes a plurality of LED modules emitting light toward an outer edge portion of the chassis and a light guiding plate for controlling the direction of light emission from the plurality of LED modules to perform illumination. The LED module is not arranged at the outer edge portion of the chassis so that moment acting on the chassis as the apparatus main body holding the LED module can be reduced as compared with the case where the LED module is arranged at the outer edge portion of the chassis. Therefore, the deformation such as bending of the chassis can be prevented.
1. A lighting apparatus comprising:
a plurality of light sources held by an apparatus main body for emitting light toward an outer edge portion of the apparatus main body; and
an optical control member for controlling the direction of light emission from the plurality of light sources to perform illumination,
wherein the optical control member is a light guiding member with a hole,
wherein the light sources are provided such that light is incident on the optical control member from a peripheral surface of the hole,
wherein an inclined surface, which is inclined to the direction crossing the direction of light emission from the light sources, is provided at an outer edge portion of the optical control member, and
wherein the optical control member allows the light propagated through the optical control member to emit to outside from the inclined surface.
2. The lighting apparatus according to claim 1 ,
wherein the optical control member is formed into a plate shape, a plurality of reflection sections are provided for diffusing the light emitted from the light source at one surface of the optical control member, and
wherein the plurality of reflection sections are provided such that the size of the area (large/small) of diffusing the light emitted from the light source corresponds to the distance (far/near) from the light source.
3. The lighting apparatus according to claim 2 ,
wherein the optical control member is formed such that the change in thickness (decrease/increase) corresponds to the distance (far/near) from the light source.
4. The lighting apparatus according to claim 1 ,
wherein the optical control member is formed such that the change in thickness (decrease/increase) corresponds to the distance (far/near) from the light source.
5. The lighting apparatus according to claim 1 ,
wherein the optical control member is formed into a plate shape, a plurality of reflection sections are provided for diffusing the light emitted from the light source at one surface of the optical control member, and
wherein the plurality of reflection sections are provided such that the size of the area (large/small) of diffusing the light emitted from the light source corresponds to the distance (far/near) from the light source.
6. The lighting apparatus according to claim 1 ,
wherein the optical control member is formed such that the change in thickness (decrease/increase) corresponds to the distance (far/near) from the light source.
