Abstract
(EN)
A lighting device (100) and an automobile (200) using same. The lighting device (100) comprises a plurality of LED chips (110), a plurality of light homogenizing rods (120) and a first lens (130) which are provided in sequence; each of the light homogenizing rods (120) is provided in a one-to-one correspondence with respect to one of the LED chips (110), and is used to homogenize light emitted from the LED chip (110), and the end face of each of the light homogenizing rods (120) faced away from the LED chip (110) is a light emitting surface (121) of the light homogenizing rod (120); and the first lens (130) is provided on one side of the light homogenizing rods (120) away from the LED chips (110), and a front focus (F) of the first lens (130) is located outside the plane where the light emitting surfaces (121) of the light homogenizing rods (120) are located. Providing the focus (F) of the first lens (130) outside the light emitting surfaces (121) can improve the uniformity of illumination light imaged through the first lens (130).

L'invention concerne un dispositif d'éclairage (100) et une automobile (200) faisant appel audit dispositif. Le dispositif d'éclairage (100) comprend une pluralité de puces à DEL (110), une pluralité de tiges d'homogénéisation de lumière (120) et une première lentille (130) qui sont disposées en séquence ; chacune des tiges d'homogénéisation de lumière (120) est disposée selon une correspondance biunivoque par rapport à l'une des puces à DEL (110), et est utilisée pour homogénéiser la lumière émise par la puce à DEL (110), et la face d'extrémité de chacune des tiges d'homogénéisation de lumière (120) opposée à la puce à DEL (110) est une surface d'émission de lumière (121) de la tige d'homogénéisation de lumière (120) ; et la première lentille (130) est disposée sur un côté des tiges d'homogénéisation de lumière (120) à distance des puces à DEL (110), et un foyer avant (F) de la première lentille (130) est situé à l'extérieur du plan où les surfaces d'émission de lumière (121) des tiges d'homogénéisation de lumière (120) sont situées. La disposition du foyer (F) de la première lentille (130) à l'extérieur des surfaces d'émission de lumière (121) peut améliorer l'uniformité de la lumière d'éclairage imagée à travers la première lentille (130).

一种照明装置(100)及应用其的汽车(200),照明装置(100)包括依次设置的多个LED芯片(110)、多个匀光棒(120)以及第一透镜(130),每一匀光棒(120)与一LED芯片(110)一一对应设置,用于对LED芯片(110)出射的光进行匀化,每一匀光棒(120)背对LED芯片(110)的端面为匀光棒(120)的出光面(121);第一透镜(130)设置在匀光棒(120)远离LED芯片(110)的一侧,第一透镜(130)的前焦点(F)位于匀光棒(120)的出光面(121)所在的平面之外。通过将第一透镜(130)的焦点(F)设置在出光面(121)以外从而可以提高经第一透镜(130)成像的照明光的均匀性。
