(EN) VEHICLE LAMP, AND METHOD FOR CONTROLLING DMD

Abstract
(EN)
A lighting device (210) generates an illumination light L1. A patterning device (220) includes a digital micromirror device (DMD) (222) that spatially modulates and reflects the illumination light L1 in accordance with a pattern signal SPTN. A DMD controller (230) generates the pattern signal SPTN. The DMD controller (230) generates a refresh pattern signal SPTN_REFRESH so that a micromirror repeatedly turns on and off during a period in which the DMD (222) is enabled and the illumination light L1 is off.
(FR)
La présente invention concerne un dispositif d'éclairage (210) qui génère une lumière d'éclairage L1. Un dispositif de formation de motifs (220) comprend une matrice de micromiroirs(DMD) (222) qui module spatialement et réfléchit la lumière d'éclairage L1 conformément à un signal de motif S PTN. Un contrôleur DMD (230) génère le signal de motif S PTN. Le contrôleur DMD (230) génère un signal de motif de rafraîchissement S PTN_REFRESH de telle sorte qu'un micromiroir s'allume et s'éteint de façon répétée pendant une période durant laquelle le DMD (222) est activé et la lumière d'éclairage L1 est éteinte.
(JA)
照明装置(210)は、照明光L1を生成する。パターニングデバイス(220)は、照明光L1をパターン信号SPTNに応じて空間的に変調し、反射するDMD(Digital Micromirror Device)(222)を含む。DMDコントローラ(230)は、パターン信号SPTNを生成する。DMDコントローラ(230)は、DMD(222)がイネーブル状態であり、かつ照明光L1がオフである期間に、マイクロミラーがオン、オフを繰り返すようなリフレッシュパターン信号SPTN_REFRESHを発生する。
