    摘要： An optical element for use in a high mounted stop lamp is formed with an LED light source mounted on a backing plate. The LED faces in a first direction to emit light towards a field to be illuminated. A light transmissive dome encloses the LED light source, the dome having refractive elements directing at least some light emitted by the LED in a second direction transverse to the first direction. At least one light guide is positioned adjacent the dome to receive light emitted by the LED that is refracted transversely by the refractive dome elements. The light guide includes light directing elements to redirect the transversely directed light towards the field to be illuminated. In this way the ineffectively directed light is recaptured and directed expand the lamp's area image to comply with legal requirements.

    摘要翻译： 用于高安装停止灯的光学元件形成有安装在背板上的LED光源。 LED朝向朝向要照明的场发光的第一方向。 透光圆顶包围LED光源，圆顶具有折射元件，该折射元件在与第一方向横向的第二方向上引导由LED发射的至少一些光。 至少一个导光体邻近圆顶定位，以接收由LED折射的折射圆顶元件横向折射的光。 光导包括导光元件，以将横向指向的光重定向待照射的场。 以这种方式，重新捕获无效的指示灯并指示扩大灯的区域图像以符合法律要求。
