Title:
情報を担持する照明効果の投射の方法及びデバイス
Document Type and Number:
Japanese Patent JP6479779
Kind Code:
B2
Abstract:
Methods, apparatus, and systems are disclosed herein for projecting lighting effects (124, 224, 324, 424) carrying light messages onto surfaces. A first of one or more light-emitting diodes (LEDs, 554) of a lighting fixture (120, 220, 320, 420, 520) may be selectively energized to produce a first coded light signal conveying a first light message associable with a first location. Light emitted from the first LED may be projected onto a first surface, e.g., as a spatially-limited lighting effect. In some embodiments, a second of the one or more LEDs of the lighting fixture may be selectively energized to produce a second coded light signal conveying a second light message associable with a second location distinct from the first location. Light emitted from the second LED may be projected onto the first surface or a second surface. Alternatively, lighting effects of various shapes and hues may convey information.
