Illumination apparatus and illumination system
First Claim
1. An illumination apparatus comprising a light-emitting unit, the light emitting unit including:
- a light guide plate having a planar shape with an upper surface and a lower surface and an opening through a center portion of the light guide plate,a light source positioned to input light into the light guide plate via an inner wall of the light guide plate, the inner wall of the light guide plate defining a periphery of the opening, anda reflective film on the upper surface of the light guide plate and configured to reflect light propagated in the light guide plate, the light-emitting unit being configured to output light from the lower surface of the light guide plate, anda housing to which the light guide plate is detachably attached, the housing having an upper surface configured for attachment to a ceiling, the housing including a lower end extending through the opening with the light source positioned between the housing and the inner wall of the light guide plate and having an apparatus holding section within an interior of the housing, the apparatus holding section configured to detachably hold an electronic apparatus, the electronic apparatus having a function unrelated to illumination by the light emitting unit,wherein,the light guide plate is detachably attached to the housing by means of a first twist and lock configuration, andthe electronic apparatus is detachably held in the apparatus holding section by means of a second twist and lock configuration.

Abstract
An illumination apparatus including a light-emitting unit and an apparatus-holding section. The light-emitting unit includes a light guide plate with a center portion being opened, a light source that inputs light from a side of an inner wall of the light guide plate, and a reflective film formed on a side of an upper surface of the light guide plate to reflect light propagated in the light guide plate. The light-emitting unit outputs light from a light output surface in opposite to the upper surface of the light guide plate. The apparatus-holding section detachably holds an electronic apparatus, is capable of removing the electronic apparatus from a side of an output direction of light from the light output surface, and includes a center of a surface parallel to the light output surface, which is positioned inside a light output area of the light output surface.
