The invention discloses a lighting device and an automobile applying the same. The lighting device comprises a plurality of LED chips, a plurality of light uniformizing rods and a first lens which arearranged in sequence, each light uniformizing rod is in one-to-one correspondence with the corresponding LED chip and used for uniformizing light emitted by the corresponding LED chip, and the end face, back to the corresponding LED chip, of each light uniformizing rod serves as a light emitting face of the corresponding light uniformizing rod. The first lens is arranged on the side, away from the LED chips, of the light uniformizing rods, and the front focus of the first lens is located outside the plane where the light emitting face of the light uniformizing rods are located. According to the invention, the focus of the first lens is arranged outside the light emitting surface, so that the uniformity of the illumination light imaged by the first lens can be improved.
本申请公开了一种照明装置及应用其的汽车,照明装置包括依次设置的多个LED芯片、多个匀光棒以及第一透镜,其中,每一匀光棒与一LED芯片一一对应设置,用于对LED芯片出射的光进行匀化,其中每一匀光棒背对LED芯片的端面为匀光棒的出光面;第一透镜设置在匀光棒远离LED芯片的一侧,第一透镜的前焦点位于匀光棒的出光面所在的平面之外。本申请通过将第一透镜的焦点设置在出光面以外从而可以提高经第一透镜成像的照明光的均匀性。
