Title (EN) LIGHT SOURCE DRIVING DEVICE AND HEAD-UP DISPLAY DEVICE
(FR) DISPOSITIF DE COMMANDE DE SOURCE DE LUMIÈRE ET DISPOSITIF D'AFFICHAGE TÊTE HAUTE
(JA) 光源駆動装置及びヘッドアップディスプレイ装置
Abstract:
(EN) Provided are a light source driving device and a head-up display device that can secure greater light stability. A light source driving device (5) drives a light source (11g) that emits green light (G) and a light source (11r) that emits red light (R). The light source driving device (5) comprises: a first voltage adjusting unit (310) that adjusts a voltage (Vg) applied to the light source (11g) on the basis of a power supply voltage from a battery (700); a second voltage adjusting unit (320) that generates a voltage (Vr) to be applied to the light source (11r) by using the voltage (Vg) as a power supply; and a first control unit (100) that performs voltage variable light-modulation processing. In the voltage variable light-modulation processing, the voltage (Vg) and the voltage (Vr) are set such that a light intensity ratio between the green light (G) and the red light (R) is equal to a desired light intensity ratio and the set voltage (Vg) and voltage (Vr) are respectively applied to the light source (11g) and the light source (11r) via the first voltage adjusting unit (310) and the second voltage adjusting unit (320).
(FR) L'invention concerne un dispositif de commande de source de lumière et un dispositif d'affichage tête haute qui peuvent garantir une stabilité à la lumière supérieure. Un dispositif de commande de source de lumière (5) commande une source de lumière (11g) qui émet une lumière verte (G) et une source de lumière (11r) qui émet une lumière rouge (R). Le dispositif de commande de source de lumière (5) comprend : une première unité de réglage de tension (310) qui règle une tension (Vg) appliquée à la source de lumière (11g) sur la base d'une tension d'alimentation électrique provenant d'une batterie (700) ; une deuxième unité de réglage de tension (320) qui génère une tension (Vr) devant être appliquée à la source de lumière (11r) à l'aide de la tension (Vg) en tant qu'alimentation électrique ; et une première unité de commande (100) qui effectue un traitement de modulation de lumière variable en tension. Dans le traitement de modulation de lumière variable en tension, la tension (Vg) et la tension (Vr) sont réglées de telle sorte qu'un rapport d'intensité lumineuse entre la lumière verte (G) et la lumière rouge (R) est égal à un rapport d'intensité lumineuse souhaité et la tension réglée (Vg) ainsi que la tension (Vr) sont respectivement appliquées à la source de lumière (11g) et à la source de lumière (11r) par l'intermédiaire de la première unité de réglage de tension (310) et de la deuxième unité de réglage de tension (320).
(JA) 光の安定性をより確保することができる光源駆動装置及びヘッドアップディスプレイ装置を提供する。 光源駆動装置(5)は、緑色光(G)を発する光源(11g)と、赤色光(R)を発する光源(11r)と、を駆動させる。光源駆動装置(5)は、バッテリ(700)からの電源電圧に基づき光源(11g)に印加する電圧(Vg)を調整する第1電圧調整部(310)と、電圧(Vg)を電力源として、光源(11r)に印加する電圧(Vr)を生成する第2電圧調整部(320)と、電圧可変調光処理を行う第1の制御部(100)と、を備える。電圧可変調光処理は、緑色光(G)及び赤色光(R)の光強度比が所望の光強度比となるように電圧(Vg)及び電圧(Vr)を設定し、第1電圧調整部(310)及び第2電圧調整部(320)を通じて、設定された電圧(Vg)及び電圧(Vr)をそれぞれ光源(11g)及び光源(11r)に印加する処理である。
