ELECTRIC LIGHT INDICATION NEEDLE AND LIGHT GUIDE |
摘要 |
<p>An electrically illuminating indicator needle and a light guiding member therefor that allow such a control as length of the needle can be varied while undergoing less unevenness in luminance and can be manufactured at a lower cost are provided. The electrically illuminating indicator needle comprises a plurality of planes of incidence, a plurality of light reflecting surfaces disposed to correspond to the planes of incidence so as to reflect light coming from the planes of incidence, a light guiding member disposed to correspond to the light reflecting surfaces so as to cause the light reflected on the light reflecting surfaces to emerge, and a plurality of light emitting diodes disposed to oppose the planes of incidence.</p> |
