Abstract
An illumination device has a base portion, a neck portion attached to the base portion, a power source and an illumination panel has an electroluminescent light source or a light guide that produces a diffuse light. The illumination panel may have roughly the thickness of a credit card and may be positioned via the flexible neck portion. The illumination device is particularly suited for use as a book light or task light due to its uniform, diffuse light, and compact size.
