ABSTRACT:
A hanger arm mechanism to hold a lamp head vertically rotatably in dental lighting equipment is directed to a mechanism designed to rotate the lamp head around the axis shaftline of the hanger arm and to stop the same in a desired position, with the result that the field of lighting of the shadowless lamp mounted inside the lamp head can freely be changed in the range of rotation of the lamp head without making the patient turn his head.
