Zusammenfassung: | To provide a lighting device that can acquire desired light distribution property and has high lighting efficiency.SOLUTION: A lighting device 1 includes: a light-emitting device 10 including a plurality of light-emitting parts 2, where the respective light-emitting parts 2 can change a light emission state indicating a state of luminosity or color of light emission; and an optical system 11 having a light condensation property in which light from the light-emitting device 10 forms a focal point in a one-by-one manner, where focal points F of respective optical systems 11 are the same position.SELECTED DRAWING: Figure 1
【課題】所望の配光特性が得られ、照明効率が高い照明装置を提供する。【解決手段】照明装置1は、複数の発光部2を備え、各発光部2は、発光の明るさ又は色の状態を表す発光状態が可変な発光素子10と、発光素子10からの光が焦点を結ぶ集光特性を有する光学系11とを1対1で備え、各光学系11の焦点Fが同一位置である。【選択図】図1 |
