摘要： PURPOSE: A LED lighting mechanism is provided to continuously and automatically control brightness in a specific space of indoor in order to maintain brightness which is brighter than desired brightness. CONSTITUTION: A LED lighting mechanism comprises a frame(2), a light emitting module(10), a sensing module(20), and a controller(30). The light emitting module includes at least one LED and emits light toward a working surface which is a reference of a brightness measurement. The sensing module is mounted on the light emitting module and includes a brightness sensor which measures the brightness of the working surface. The controller compares a measured brightness value which is the brightness of the working surface with a predetermined reference brightness value and gradually enhances or lowers a LED light intensity in order to make the measured brightness value close to the reference brightness value.
