US Patent 7216999 Chemiluminescent illumination device with attached tactile sleeve

A chemiluminescent lighting device having a flexible casing surrounding the source of light. A separate transparent, translucent or opaque sleeve is placed about the casing to improve the gripping and the aesthetic feel of the device while passing the light. The sleeve may be in the form of a spiral or net exposing portions of the casing. The sleeve may include colored polymers to produce multi-colored effects. The sleeve may also include fluorescers to retain intensity and/or change colors. The lighting device enhances the visual appeal of novelty items such as necklaces and bracelets, and provides a tactile grip when used as a hand-held illumination device.
