ILLUMINATED POINTER INSTRUMENT FOR A MOTOR VEHICLE
20170178754 · 2017-06-22 · ·

A pointer needle for an indication device of a motor vehicle has a transparent optical waveguide that receives light propagating along a direction of propagation at a light-entry side, and emits the light in an emission direction at a light-exit side. The optical waveguide has a scattering side opposite to the light-exit side, the scattering side having steps arranged offset to one another across the propagation direction. When the steps are irradiated by light, the pointer needle provided in the indication device can clearly be perceived in the dark.

Stepper pointer

A gauge assembly which has a gauge surface including graphics representing a vehicle operating parameter. A pointer arm is provided which is made out of a light guide or light transmitting material. The pointer arm includes a step portion in an operative portion of the second bottom surface for reducing light received by said second surface adjacent the step portion and providing an overall even light throughout the operative illuminated viewing surface of the pointer arm.
