Abstract
A hand-held power tool includes a housing defining a first longitudinal axis and an illuminating assembly mounted to the housing. The illuminating assembly includes lighting elements distributed on the housing around the first longitudinal axis, a circuit board electrically connected to the lighting elements, a main body, and a fixing member. The lighting elements are supported by the circuit board. The main body partially covers the lighting elements and the circuit board. The lighting elements and the main body are fixed to the housing by the main body cooperative with the fixing member. The lighting elements are distributed around the first longitudinal axis so that light of the lighting elements can be emitted from multiple different angles, shadows are avoided in corresponding zones, and therefore the lighting elements can be called shadow-less lighting elements.
