The invention relates to a lighting device (10), comprising a flat light guide (12), which has a protective layer (18) on the light output side (30) thereof at least in an observation region (32), which protective layer is directly connected to a light guide core (16), into which light (24) from at least one light source (22) can be coupled via at least one coupling-in side (20) via the light guide core (16), the light guide (12) has an outcoupling structure (28) on a rear side (26) thereof opposite the light output side (30), which outcoupling structure is designed to deflect the light (24) in such a way that the deflected light (24) is output from the light guide (12) via the light output side (30) into the environment. And a housing (14) which covers the rear side (26) on the side facing away from the light output side (30) in such a way as to cover at least the entire viewing region (32) of the light guide (12) and which is connected to the light guide (12) in a dust-and stain-proof manner.
本发明涉及一种照明设备(10),其具有扁平的光导(12),该光导(12)在其光输出侧(30)上至少在观察区域(32)内具有与光导芯(16)直接连接的保护层(18),来自至少一个光源(22)的光(24)可通过至少一个耦合输入侧(20)经由光导芯(16)耦合输入到该光导中,并且该光导在其与光输出侧(30)相对的背侧(26)上具有耦合输出结构(28),该耦合输出结构构造为用于偏转光(24),使得被偏转的光(24)通过光输出侧(30)从光导(12)输出至环境中;并且具有壳体(14),其以至少覆盖光导(12)的整个观察区域(32)的方式在远离光输出侧(30)的一侧覆盖背侧(26),并以防尘和防污渍的方式与光导(12)连接。
