<p>PROBLEM TO BE SOLVED: To provide a lighting apparatus which enables setting an target intensity of illumination for each scenes with ease regardless the number of related scenes. SOLUTION: The lighting apparatus is constructed by a control part 1 which controls the light output of lamp with feedback so as to make the light intensity of illuminated surface become almost constant, depending on the information of scene memorized in memory part, and a memory part 2 which memorizes the plural scenes produced by light output of lamp, and a light sensor 3 which detects the light intensity of illuminated surface, and a luminaire 4 which retains lamp, and a means of memory/reproduction 5 for the memorization of memorized scene or reproduced scene. At least one scene out of plural scenes is specified as a standard scene, and the memory part 2 memorizes the lightness of standard scene and that of other scenes which are expressed by the magnification against the lightness of standard scene.</p> |
