车辆显示设备
摘要：
一种车辆显示设备 (100)被提供有围绕显示区域（11）外周的环境光发光区域（13）。环境光源（43）发射光，所述光随后由环境光导光体（50）引导到丙烯酸圆柱体（60）中。随后将引导的光从丙烯酸圆柱体的光输出端面（62）朝向光输出方向（OD）输出。光输出端面形成环境光发光区域。车辆显示设备包括光收集结构（70），其朝向光输出方向收集从光输出端面输出的输出光（OB）。朝向光输出方向收集输出光能够实现在与光输出方向不同的方向上的光泄漏的减少，提高了环境光发光区域的输出亮度。
摘要（英）：

A vehicular display apparatus (100) is provided with an ambient-light luminous region (13) that surrounds an outer periphery of a display region (11). An ambient light source (43) emits light, which is then guided by an arribient-light guide body (50) into an acrylic cylindrical body (60). The guided light is then outputted from a light output end face (62) of the acrylic cylindrical body towards a light output direction (OD). The light output end face forms the ambient-light luminous region. The vehicular display apparatus includes a light collection structure (70) that collects an output light (OB), which is outputted from the light output end face, towards the light output direction. Collecting the output light towards the light output direction enables the reduction of a light leakage to a direction different from the light output direction, improving an outputted luminance of the ambient-light luminous region.
