Abstract: A generator and lighting assembly is provided for use on a mechanism, e.g. a power driven tool, having a shaft that is rotated during use. The assembly includes a rotor assembly 122 including a rotor shaft 102 affixed to the mechanism shaft, and a permanent magnet 132 supported on the rotor shaft for rotation therewith. A stator assembly 124 is also provided, and includes a body presenting pair of electrically conductive arms 138 extending on opposite sides of the rotor and an electrically conductive shank 140 connecting the arms together, and a winding 136 of electrically conductive wire supported on the body and presenting a pair of opposed ends. The assembly includes a lamp assembly 128 for providing illumination to an area to be lighted, and includes a light emitting diode (LED) embedded in a solid transparent bulb formed of a synthetic resin composition.

Abstract: A miniature electric generator and lighting apparatus is provided for use in a power-driven tool. The apparatus includes a rotor assembly 22 having a permanent magnet, and a stator assembly 24 within which the shaft and magnet are received. The stator assembly 24 includes a pair of electrically conductive arms 38 extending on opposite sides of the rotor, an electrically conductive shank 40 connecting the arms together, and a winding 36 of electrically conductive wire presenting a pair of opposed ends. A lamp 54 is connected to the ends of the winding by a circuit 52 so that it is powered upon rotation of the shaft. A housing assembly 30 supports the stator assembly 24 on the output shaft of the tool, and is secured to the tool. The housing assembly 30 and cooperating structure 42 position the stator assembly 24 relative to the magnet 32 to prevent contact between the stator element 34 and the magnet during rotation of the output shaft 14.

Abstract: A pneumatic lighting apparatus for use with a pneumatically driven tool includes a pneumatic motor driven by compressed air, and an electrical generator that is driven by the mechanical output of the motor for generating an electrical current. A lamp is provided in a circuit with the generator for emitting light adapted to be directed onto an area in which the tool is being used. A conduit is provided which is connected between the outlet of the motor and an inlet of the tool in order to deliver compressed air from the apparatus to the tool. In order to permit control of the lighting apparatus independent of operation of the tool, a control valve is provided for controlling the flow of compressed air through the motor, and an exhaust valve controls the flow of compressed air between the conduit and an exhaust.
