Abstract
Embodiments of a magnetostrictive device, a dental lighting system, a method of illuminating a lighting apparatus and a lighting apparatus are disclosed. The embodiments may include a lighting apparatus with a light source, an electrical power storage device and a switch. When the switch detects a magnetic field, the switch may complete an electrical connection between the electrical power storage device and the switch, thus illuminating the light source. The magnetic field may be magnetostrictively or non-magnetostrictively generated, and maybe be produced by a receptacle, a hand-piece or the lighting apparatus itself. A user may switch the light source on and off. In a magnetostrictive device, the light may be illuminated even when a tip is not activated, and the electrical power storage device may be inductively re-charged. The lighting apparatus may be included in an insert of a magnetostrictive device, such as a magnetostrictive ultrasonic hand-held dental device.
