    • An apparatus for illuminating instrument pointers comprises a dial board having a shaft hole, pointer shafts provided perpendicularly to a pointer shaft drive unit and projecting through the shaft hole to the front of the dial board, a light conductive member having a light receiving section and a light transmission section made of a transparent material and disposed behind the dial board, a plurality of instrument pointers each having a collar section and a pointer section made of a transparent material and mounted on the pointer shaft such that a light beam emitted from the light transmission section is introduced through the collar section, and a light emitting member provided oppositely to the light receiving section. A light beam from the light emitting member is propagated through the light conductive member to the collar section and then to the pointer section, so that each instrument pointer is illuminated.
    • 用于照明仪表指针的装置包括:具有轴孔的拨号板,与指针轴驱动单元垂直设置的指针轴,并通过轴孔突出到指示板的前部;导光部件,具有光接收部和 光透射部分由透明材料制成并设置在表盘后面;多个仪器指针,每个仪器指针都具有一个由透明材料制成的凸缘部分和指针部分,并安装在指针轴上,使得从光传输 通过轴环部分引入截面,以及与光接收部相对设置的发光部件。 来自发光构件的光束通过导光构件传播到套环部分,然后传播到指针部分,使得每个仪器指针被照亮。
