    Abstract: A power tool includes a motor, an output shaft, a chip-on-board light emitting diode, and a light cover. The output shaft is rotated by a rotational force of the motor. The chip-on-board light emitting diode is disposed around the output shaft. The chip-on-board light emitting diode includes: a substrate including a circular ring portion; and an LED chip disposed on a front surface of the circular ring portion. The light cover is fixed to the substrate. The light cover includes: an outer cylindrical portion disposed radially outside with respect to the circular ring portion; and a light transmission portion through which light emitted from the LED chip passes. An opening is provided in a lower portion of the outer cylindrical portion.

    Abstract: A light unit is less likely to have lower light emission performance upon receiving a shock. An electric work machine includes a motor, a housing including a motor compartment accommodating the motor and a grip protruding downward from the motor compartment, an output unit located frontward from the motor and operable with a rotational force from the motor, a substrate extending above, on a left, and on a right of the output unit, and a plurality of light emitters mounted on a front surface of the substrate at intervals in a circumferential direction of the output unit. A light emitter of the plurality of light emitters nearest an apex of the substrate immediately above the output unit is at a position shifted circumferentially by a predetermined angle from the apex.

    Abstract: A power tool attachment efficiently guides light and provides sufficient illumination when attached to a power tool. A power tool attachment is attachable to a power tool to cover a light source included in the power tool. The power tool attachment includes a light guide being a single member made of a transparent resin. The light guide includes a light receiver that receives light from the light source when the power tool attachment is attached to the power tool, and a light emitter that outputs the received light.
