Shadowless lighting design for a power tool

A rotary hammer comprising:

• a housing including a motor housing and a secondary housing;
• a motor situated within the motor housing;
• an output device configured to provide a rotational output, an axial hammering output, or both the rotational output and the axial hammering output;
• a transmission mechanism configured to transmit rotational energy from the motor to the output device of the rotary hammer, wherein at least a portion of the transmission mechanism is situated within the secondary housing;
• a light holder that includes a plurality of light sources distributed around an output axis of the rotary hammer on which the output device is located, wherein the light holder includes:
• a ring portion mounted to a front surface of the secondary housing, wherein the ring portion surrounds the output axis, and
• an extending arm that extends downward and away from the ring portion in a channel of the secondary housing, wherein the channel is formed by protrusions on a bottom peripheral surface of the secondary housing, and wherein the extending arm extends rearwardly at least halfway along an axial length of the secondary housing in a direction parallel to the output axis;
• and
• lighting power wires configured to provide power to the plurality of light sources, wherein the lighting power wires are located within the channel and are covered by the extending arm;
• wherein the ring portion includes a plurality of through-holes that are each configured to receive a fastener;
• wherein each fastener is received in a respective hole on the front surface of the secondary housing to secure the light holder to the secondary housing.
