The subject innovation is formed in that a cylindrical, built as a light source housing and the vertical that is provided with an upper side an open light source mounting space for mounting a light source for irradiating light to the upper side of this lighting device can adjust the irradiation range for the opening of the light housing the shape of the adjustment to be inserted so as to cover the housing and, pivotally mounted on the inner side of the adjustment housing and characterized in that it comprises a rotor plate formed hole radially passing through one another of a different size light irradiation surface by selectively according to the user's needs maintenance may provide an irradiation surface of a variety of patterns, and can reduce the failure by minimizing the component parts in accordance with the scaling of the illuminated surface, can be easily repaired even when a failure occurs, devices for removing the it is easy to become effective.
