A lighting device (91) comprising an optical block (170) having: a coupling portion (171) having a coupling face (175) arranged to couple light (190) into the optical block (170); and a waveguide portion (172) extending away from the coupling portion (171) and designed to guide light (190) by multiple reflections (50) between the top side (271) and the bottom side (272) of the waveguide portion (172). The optical block (170) further comprises a holographic optical element formed in the waveguide portion (172) and designed to reconstruct a hologram by means of light.
一种照明装置(91),包括光学块(170),该光学块具有:耦合部分(171),该耦合部分具有耦合面(175),该耦合面被布置成将光(190)耦合到光学块(170)中;以及波导部分(172),该波导部分背离耦合部分(171)延伸并且被设计成通过使光(190)在波导部分(172)的顶侧(271)与底侧(272)之间进行多次反射(50)来引导光。光学块(170)还包括全息光学元件,该全息光学元件形成在波导部分(172)中并且被设计成借助于光来重建全息图。
