    • A light transmitting strip or light pipe 2 is used to illuminate an elongate area along which the light pipe 2 extends. The illumination is provided by light emanating laterally relative to the axis of the light pipe, and the light intensity is substantially uniform, at least to an observer, along the length of the light pipe 2. The light pipe 2 has a clear light guide section 4 and an opaque section 10 that is separated from the light guide section 4 by an air gap 8. The clear section 4 and the opaque section 10 are joined by top and bottom couplings 12 and 14, and the two sections are formed by coextruding an acrylic resin through a single coextrusion die. Light emitted laterally from the light guide 4 toward the arcuate opaque section 10 is reflected laterally through the clear light guide 4 transverse to the axis of the light pipe 2, so that all light extends through the front surface 6 of the light guide 4. By separating the reflecting opaque section 10 from the clear light guide 2 by an air gap 8, the lighting intensity can be more uniform over the length of the lighting strip or light pipe.
    • 透光条或光管2用于照亮光管2延伸的细长区域。 照明由相对于光管的轴线横向散发的光提供,并且光强度至少对于观察者而言沿着光管2的长度基本上是均匀的。光管2具有透明导光部分 4和不透光部分10,其通过气隙8与导光部分4分离。透明部分4和不透明部分10通过顶部和底部联接器12和14连接,并且两个部分通过共挤出 丙烯酸树脂通过单个共挤出模头。 从导光体4朝向弓形不透明部分10侧向发射的光横向于光导管2的轴线横向透过透明导光体4反射,使得所有光线延伸通过光导4的前表面6。 通过气隙8将反射不透明部分10与透明光导2分开,照明强度在照明条或光管的长度上可以更均匀。

    • A light pipe assembly includes a lamp assembly and a light pipe. The lamp assembly has a housing that holds a light source configured to emit light. The light pipe is elongated between an attachment end and an opposing distal end. The attachment end is received in the housing of the lamp assembly. The light pipe receives light emitted by the light source. Additionally, the light pipe includes surface elements that are configured to permit the light to emanate from the light pipe between the attachment and distal ends. The surface elements are arranged in a pattern that provides a predetermined distribution of light emanating from the light pipe.
    • 光管组件包括灯组件和光管。 灯组件具有保持构造成发光的光源的壳体。 光管在附接端和相对的远端之间是细长的。 附件端被接收在灯组件的外壳中。 光管接收光源发出的光。 另外,光管包括表面元件,其被配置为允许光从附接端和远端之间的光管发出。 表面元件布置成提供从光管发出的光的预定分布的图案。
