Abstract
Grooves are formed along the length inside a frame member formed by integrating a lens and reflecting frames. A base plate on which light emitting diodes are arranged in a line is held in the frame member by being inserted in the grooves. The lower part of the frame member is open so that heat is released directly from the base plate, thereby preventing the warp of the base plate and the frame member due to an increase in temperature.
