Abstract
An illumination apparatus includes a transparent case, an opaque member, a ring-shaped light emitting device, and a ring-shaped transparent cover. The transparent case has a central region. The opaque member is disposed on the central region. The ring-shaped light emitting device is disposed in the transparent case corresponding to the central region. The ring-shaped transparent cover is disposed on the ring-shaped light emitting device and has a first arc-shaped ring portion relatively close to the opaque member and a second arc-shaped ring portion relatively away from the opaque member. A refraction microstructure region is formed on an inner surface of the first arc-shaped ring portion for refracting light emitted by the ring-shaped light emitting device.
