Abstract
A lighting apparatus which enables a shade to be easily attached, detached and rotated with a simple structure and an enhanced degree of freedom in design. Grooves defining arc-shaped portions , respectively, are formed around an axis of a head , to which is mounted a fluorescent light bulb . A shade which is formed with protrusions opposite to the grooves is mounted to the head so as to cover the fluorescent light bulb . By pressing the protrusions of the shade into the grooves of the head , the shade can be very easily mounted to the head . By lifting up the shade from the head , the shade can be very easily removed from the head . In addition, the shade can be rotated by allowing the protrusions formed on the shade to slide along the arc-shaped portions . As such shade allows a simple integral structure, degree of freedom in designing a lighting apparatus can be enhanced.
