The invention provides a low-cost optical device, a traveling direction display device and a vehicle, wherein the optical device has good light utilization efficiency and can display complicated patterns with a simple structure. An optical device (100) for displaying a light-condensing mark (400) is provided with a light source (110) and an optical element for condensing light emitted from the light source (110) on an irradiation surface (301), the deflection surface of the optical element is divided into a plurality of regions, and light emitted through each region on the deflection surface of the optical element forms a partial irradiation image on the irradiation surface (301) corresponding to each region on the deflection surface. The partial irradiation images are combined to form at least one condensation mark (400) on the irradiation surface.

    本发明提供一种光的利用效率良好、能够用简单的结构显示复杂的图案的廉价的光学装置和行进方向显示装置以及车辆。显示聚光标记(400)的光学装置(100)包括光源(110)和使从光源(110)出射的光在照射面(301)上聚光的光学元件,光学元件的偏转面被分割成多个区域,经由光学元件的偏转面上的各区域出射的光在照射面(301)上形成与偏转面的各区域对应的部分照射像,各部分照射像被组合而在所述照射面上形成至少一个聚光标记(400)。
