Abstract
A focusing structure comprises a fixing base, an adjusting rod, an adjusting button and an elastic component. The adjusting rod is located through the fixing base rotatablely and provided with a plurality of position-restricted parts. The adjusting button is disposed slideably on the fixing base and clamped with one of the plurality of position-restricted parts in a singly selective manner to enable the adjusting rod to be located in different positions relative to the fixing base. The elastic component is held between the adjusting button and the fixing base to provide elastic restoring force for the adjusting button. The focusing structure slides relative to the fixing base by the adjusting rod and locates the adjusting rod slideably by the adjusting button and the elastic component, so that a lamp holder is located in different positions of a reflector and the focus of a light fitting is changed. Therefore, the light fitting can be focused without replacing the reflector and focus is more convenient. The invention also provides the light fitting having the focusing structure.
