Illumination apparatus and illumination system

摘要

An illumination apparatus includes 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.

1. An illumination apparatus, comprising:
a light-emitting unit including (a) a light guide plate having oppositely facing upper and lower planar surfaces, (b) an opening through a center of the light guide plate, (c) a light source positioned to input light into the light guide plate via inner wall of the light guide plate defining a periphery of the opening, and (d) a 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; and an apparatus-holding section extending through the opening and configured to detachably hold an electronic apparatus at the lower planar surface side of the guide plate and inside a light output area of the lower planar surface, the light output area being an area from which light is output, wherein,
the light emitting unit is detachably attached to an outer periphery of the apparatus-holding section, andthe electronic apparatus is detachably attached to an inner periphery of the apparatus-holding section;the light emitting unit and the apparatus holding section are attached together by means of a first mating pin and groove twist and lock arrangement in which the apparatus holding section has grooves and the light emitting unit has pins, andthe electronic apparatus and the apparatus holding section are attached together by means of a second mating pin and groove twist and lock arrangement in which the apparatus holding section has pins and the electronic apparatus has a housing with grooves.
