Description

A rotating structure and its lighting fixture

Technical field

The present invention relates to the field of lighting technology, and in particular to a rotating structure and its lighting fixture.

Background technique

The rotating structure often appears between two relatively rotating first and second main parts, such as in lighting fixtures, which usually include a first lighting component with an LED light source and a handle component housing a battery (in this case, the handle component is the first main part, and the first lighting component is the second main part). Folding work lights can be used for inspection and irradiation of paint surfaces at home or car paint surfaces, etc. The rotating structures of existing folding work lights are all fixed, such as the folding light CN214467981U, which means that the lighting component does not move axially and is a single movable rotation with a single function. The lighting component is located on the handle after folding and unfolding. in the middle position; therefore, if you want to design multiple lighting components, you can directly make two lighting components. However, the two lighting components can only be designed to cross. After unfolding, the light source cannot be linear, resulting in a brightness difference and affecting the light source illumination. The uniformity affects the detection lighting of paint surfaces, walls and other surfaces, making it inconvenient for painters to work, so there is room for improvement.
