Abstract: A self-contained and convertible dental instrument system includes both a lighted mirror and a direct illuminator. A hand piece has a handle section, including a battery in a housing, and a dual attachment section to receive a mirror and a light source. The illumination can be by reflection by said mirror or directly upon removal of the mirror from alignment with the light source. The handle and attachment sections preferably form a Y with the handle section reduced in size for balance and enhanced manipulation. The light source is an LED, is connected through wires in the hand piece to the battery and is controlled by a switch on the battery housing. A lens for the LED is attached by a snap-on adapter. For close contact illumination in the dental cavity, the lens includes a translucent rod, also attached by an adapter. The mirror and rod are rotatable for angular positioning to improve the illumination and the viewing.

Abstract: A headlight for use on a head gear, or the like, is provided. A LED serves as a light source mounted on a clamp for attachment to the head gear in any one of the three orientation planes. A universal mount of the light source on the clamp allows the light beam to be directed by up and down, as well as by side-to-side, manual adjustment. The beam covers substantially all frontal objects without changing the position of the clamp. A pair of pivot connections, or a ball and socket mechanism, exhibit sufficient frictional engagement to hold the light source in position. The pivot connection may be used to support the ball on the light source in the second embodiment. The socket is split along its curvature lines and an O-ring extends around the split socket to assure frictional engagement to hold the light source in position.
