PERSONAL CARE DEVICE WITH ILLUMINATION

A personal care device is proposed with a main body and attachment and wherein the attachment comprises an optical arrangement or light patterning means which receives light supplied at a light input area and processes or guides the light in such a way as to generate an illumination pattern in the attachment body which defines a 3D geometric shape or structure. The light patterning means or optical arrangement has a plurality of portions, which are each arranged to be optically activated upon supply of light to a different respective light input area, or to the same light input area but at a different light input angle, and each, upon optical activation, generating a different portion of the overall 3D illumination pattern. A set of multiple light sources are provided in the main body for respectively supplying light into different of the portions of the optical arrangement or light patterning means, and are dynamically controlled by a controller to generate a dynamically varying overall 3D illumination pattern.
