This utility model provides a rotatable work light, relating to the field of lighting technology. The control device is housed within the lampshade and includes multiple first lamp groups and a conical knob. Rotating the conical knob controls the first lamp groups to extend or retract axially along pre-drilled holes in the lampshade. When extended, the first lamp groups are in an
active state; when retracted, they are in a non-
active state. The control device also includes a screw, a base, a base fixing rod, a slider, a conical knob cover, and a second lamp group. The switching device includes a connecting block, a fixing block, a limiting block, a sliding plate, a spring fixing rod, a spring, a rack, a switch control block, an
encoder, gears, and a main shaft, enabling the extension and retraction of the first lamp groups to synchronize with the switching of the second lamp group, and adjusting the brightness of the first lamp groups via the
encoder. Furthermore, a folding frame is included to support the work light. This utility model is easy to operate, offers flexible lighting, and has a compact structure, improving work efficiency and portability.
