US Patent 7048406 Mirror device having automatic light device

A mirror device includes one or more light devices disposed behind a mirror, to generate lights to light the mirror. A remote detecting device may be used to detect whether one or more users go toward or go close to the mirror or not, and to actuate the light device to generate the lights when the users are detected to go toward the mirror. The light device may thus be actuated to light the mirror without being contacted by the users or without being operated by the users manually. A control device may be used to actuate the light device to generate the light. The remote detecting device includes a light emitting device to generate a light to detect whether the user goes toward the mirror or not.
