Luminous light band of button of automotive interior control panel
2013
A luminous light band of buttons of an automotive interior control panel comprises a control panel which comprises multiple parallel buttons. Each button is arranged in a button support. A light emitting optical conductor is arranged between each button and the corresponding button support. A light emitting face of each light emitting optical conductor is exposed in one side of the junction part of the button and the button support and is adjacent or opposite to the control panel beside the button. Each light incident face of the light emitting optical conductor is exposed on the bottom of the button support. A light source coupling optical conductor is arranged outside the light incident plane of each light emitting optical conductor. The light incident planes of the light emitting optical conductors face the light emitting faces of the light source coupling optical conductors. A light emitting diode is arranged outside the light incident planes of the light source coupling optical conductors. The light source coupling optical conductor and the light emitting diode are fixed at a rear side of the control panel. Emitted lights from the light optical conductors are matched with a curved surface of the control panel beside the buttons, so that a light band perceived by human's eyes is uniform in brightness and width.
