発明の名称
(DE) Vorrichtung zur Beleuchtung eines Fahrzeuginsassen mit Infrarotlicht
(EN) Apparatus for illuminating a vehicle occupant with infrared light
(FR) Appareil d'éclairage d'occupant de véhicule avec lumière à infrarouges
要約
(EN)
A vehicle occupant (22) is illuminated with infrared light by an apparatus including a display apparatus (20/20') illuminated with visible light for displaying information to the occupant (22) and an infrared illuminator (28) hidden behind the display apparatus (20/20') for illuminating the occupant (22) through the display apparatus (20/20'). In a preferred embodiment, the display apparatus (20/20') is a liquid crystal display (LCD) (32) mounted in the vehicle instrument panel (14) for displaying images and data to the driver (22), and infrared light emitted by the infrared illuminator (28) is transmitted through the LCD (32) to illuminate the occupant (22).
