    • A document illuminator includes a light-transmissive element having an embedded source of illumination fitted in a cavity formed therein. The light-transmissive element preferably has one or more optical notches and preferably is encased in an opaque surround to promote total internal reflection of the light rays emanating from the LED. The one or more optical notches may include a dual-V notch or an elliptical notch. The reflected light rays are collected at an aperture which in turn transmit light at high power and highly uniform illumination profile to illuminate a document.
    • 文件照明器包括具有嵌入在其中形成的空腔中的嵌入式照明源的透光元件。 透光元件优选地具有一个或多个光学凹口,并且优选地被包围在不透明环境中以促进从LED发出的光线的全内反射。 一个或多个光学凹口可以包括双V凹口或椭圆形凹口。 反射的光线被收集在孔口处,孔口又以高功率传输光并且高度均匀的照明轮廓照射文件。
