The invention provides an optical system, an illumination system, a display system, and a moving object. An optical system (100) is provided with a light guide member (1) and a plurality of prism sheets (3). The light guide member (1) has an incident surface (10) on which light is incident, and a first surface (11) and a second surface which face each other, and the second surface is a light emission surface. The plurality of prism sheets (3) are provided on the first surface and reflect light passing through the inside of the light guide member (1) toward the second surface. The plurality of prism sheets (3) include two or more prism sheets (3) whose inclination angles ([theta] 10) with respect to the incident surface differ according to at least positions in a first direction along both the incident surface and the first surface. Among the plurality of prism sheets (3), the inclination angle ([theta]10) of two or more prism sheets (3) is determined such that the light emitted from the second surface (12) is directed outward or inward in the first direction with respect to the reference light beam (L100) as the prism sheets (3) are positioned closer to both ends of the first surface in the first direction.
本公开提供一种光学系统、照明系统、显示系统以及移动体。光学系统(100)具备导光构件(1)和多个棱镜片(3)。导光构件(1)具有光入射的入射面(10)和相互对置的第1面(11)及第2面,第2面是光的射出面。多个棱镜片(3)设置在第1面,将穿过导光构件(1)的内部的光朝向第2面反射。多个棱镜片(3)包括相对于入射面的倾斜角度(θ10)至少根据沿着入射面及第1面这两者的第1方向上的位置而不同的2个以上的棱镜片(3)。在多个棱镜片(3)中,2个以上的棱镜片(3)的倾斜角度(θ10)被决定为:越处于靠近第1面的第1方向上的两端的位置,则越使从第2面(12)射出的光相对于基准光线(L100)而朝向第1方向的外侧或内侧。
