Illumination and display device |
摘要 |
An illumination device for a display instrument is described which is used to illuminate two sets of scale markings and to separately illuminate a pointer scale of the display instrument. The light from a light source is guided past light funnels that are used to illuminate the pointer scale by an optical waveguide. This provides an efficient and economical means of illuminating a display instrument of this type.
