Abstract: A compact, light weight and energy-efficient illumination module is described for inclusion into a variety of portable products such as an organizer, a book and a handbag. The illumination module allows for convenient, energy-efficient viewing, reading or writing with the portable products. The illumination module comprises a light source, a standalone electrical power source such as a battery, a switching electrical circuit having an integrated user-operated switch, an enclosure and a mechanically adjustable attachment for including the enclosure into the portable products. Upon activation, the light source of the illumination module emits a locally directed spatial illumination light pattern onto the portable product for reading.
