1. A power tool comprising:
- a housing;
a motor received in the housing;
a tool holder moveable relative to the housing and configured to hold a tool;
a transmission received in the housing and configured to transmit motion from the motor to the tool holder;
a light unit coupled to the tool holder and configured to move together with the tool holder when the tool holder moves relative to the housing;
a first electrical conductor electrically connected to a source of electrical power and coupled to the housing;
a second electrical conductor electrically connected to the light unit, and coupled to the tool holder to move with the tool holder when the tool holder moves relative to the housing;
wherein the first electrical conductor is configured to transmit electrical power from the source of electrical power to the second electrical conductor in order to cause illumination of the light unit.

Abstract
A power tool having a light for illuminating an area proximate a movable end effector. The light may be mounted in such a way as to transmit light through a rotatable collar on the power tool, through or through a member of a housing of the power tool, or from the moving end effector. The light may be powered by a power source that is used for moving the end effector or from a generator that generates electrical power when the power tool is used.

14. A tool holder for a power tool comprising:
-
a holder body configured to hold a tool and adapted to be movably attached to a housing of a power tool so that movement of a motor in the housing of the power tool causes motion of the holder body, via at least one of an output shaft and a transmission coupled to the holder body, relative to the housing of the power tool; a light unit coupled to the holder body and configured to move together with the holder body when the holder body moves relative to the housing; and an electrical conductor electrically connected to the light unit, coupled to the holder body to move with the holder body when the holder body moves relative to the housing, and configured to transmit electrical power from a source of electrical power disposed in the housing of the power tool to the light unit to cause illumination of the light unit, wherein the electrical conductor moves relative to the source of electrical power when the holder body moves relative to the housing. - View Dependent Claims (15, 16, 17, 18, 19, 20)
