ABSTRACT:
A lighting device characterized by its light weight and ease of handling. One application of the lighting device is a lighted bookmark which can be placed between the pages of a book and also functions as a portable book light while reading. The invention utilizes a novel neck mechanism possessing a memory effect that repeatedly returns the light-bearing neck to its original curved position when extended. The light-bearing neck of the bookmark can be retracted to fit within the body of the bookmark and can also be pushed to extend out of the bookmark, causing the light to automatically energize above the pages of a book when reading. The novel light-bearing neck mechanism can be successfully incorporated into other lighting devices such as a lighted notepad and the like.
