说明书 发明名称：机顶盒导光柱组件及机顶盒 技术领域  Title: Invention Name: Set Top Box Light Guide Column Assembly and Set Top Box Technical Field

[0002] 导光柱是一种将光以较小的损耗从光源传输到距离该光源一定距离的一个点的 装置。 在机顶盒上， 机顶盒导光柱主要是将 PCB板上 LED灯的光传输到机顶盒面 板上， 显示机顶盒的运行状态， 也可以聚集和指引光线用作 LCD显示屏的背光 ， 同吋也可以用来照亮透过式窗口上的图案、 纹理等。 导光柱的材料一般选用 光学材料制成， 如亚克力、 PC等。  [0002] A light guide is a device that transmits light from a light source with a small loss to a point at a distance from the light source. On the set-top box, the set-top box light guide column mainly transmits the light of the LED light on the PCB board to the set-top box panel, and displays the running state of the set-top box, and can also gather and direct the light to be used as the backlight of the LCD display screen, and the same can also be used for photographing. Bright patterns, textures, etc. on the transmissive window. The material of the light guide column is generally made of optical materials such as acrylic, PC, and the like.
[0003] 目前， 机顶盒中 LED灯主要分为插件式和贴片式两种。 插件式 LED光源较为分 散， 适合用于带有大镜片的机顶盒。 插件式 LED其带有较长的引脚， 可以调整发 光的方向。 而贴片式 LED光源较为集中， 一般需要使用导光柱进行发光方向的改 变。 贴片式 LED与插件式 LED相比光源更集中， 更多的在机顶盒中使用， 但是贴 片式 LED比插件式 LED成本高很多， 这就大大提高了机顶盒的成本， 不利于机顶 盒的推广使用。  [0003] At present, LED lights in set-top boxes are mainly divided into plug-in type and patch type. Plug-in LED sources are more diffuse and suitable for set-top boxes with large lenses. Plug-in LEDs have longer pins that adjust the direction of the light. The SMD LED light source is more concentrated, and it is generally required to use a light guide column to change the illumination direction. SMD LEDs are more concentrated than plug-in LEDs, and are more used in set-top boxes, but SMD LEDs are much more expensive than plug-in LEDs, which greatly increases the cost of set-top boxes and is not conducive to the promotion of set-top boxes. .
