Abstract
(EN)
A color foil according to the present invention has a plurality of transmission regions (R, G, B, C, W, Y) on which light from a light source is incident, and through each of which is transmitted a different wavelength of light. A detection unit according to the present invention detects environment information. A power supply unit according to the present invention supplies electric power to the light source. A control unit according to the present invention controls supply power supplied by the power supply unit to the light source. The transmission regions (R, G, B, C, W, Y) on which the light from the light source is incident vary in sequence. When the environment information satisfies a predetermined condition, the control unit changes the supply power in synchrony with the plurality of transmission regions (R, G, B, C, W, Y).

Une feuille de couleur selon la présente invention a une pluralité de régions de transmission (R, G, B, C, W, Y) sur lesquelles une lumière provenant d'une source de lumière est incidente, et à travers chacune desquelles est émise une longueur d'onde différente de lumière. Une unité de détection selon la présente invention détecte des informations d'environnement. Une unité d'alimentation électrique selon la présente invention alimente la source de lumière en énergie électrique. Une unité de commande selon la présente invention commande l'énergie électrique fournie par l'unité d'alimentation électrique à la source de lumière. Les régions de émission (R, G, B, C, W, Y) sur lesquelles la lumière provenant de la source de lumière est incidente varient en séquence. Lorsque les informations d'environnement satisfont une condition prédéterminée, l'unité de commande change l'énergie électrique de manière synchrone avec la pluralité de régions de transmission (R, G, B, C, W, Y).

カラーホイールは、光源からの光が入射し、それぞれ異なる波長の光を透過する複数の透過領域(R、G、B、C、W、Y)を有する。検出部は、環境情報を検出する。電力供給部は、光源に電力を供給する。制御部は、電力供給部が光源に供給する供給電力を制御する。光源からの光が入射する透過領域(R、G、B、C、W、Y)は順次変化する。環境情報が所定の条件を満たす場合、制御部は、複数の透過領域(R、G、B、C、W、Y)に同期 して供給電力を変更する。
