Claims17
A meter assembly for a vehicle instrument panel, the meter assembly comprising:
- a reflector case including a plurality of light guides extending from an inner surface of the reflector case, neighboring ones of the plurality of light guides have different lengths and extend different distances from the inner surface of the reflector case;
- a circuit board including a plurality of light emitting elements, the circuit board is arranged such that the light emitting elements are aligned with different ones of the plurality of light guides;
- and
- a main case arranged between the circuit board and the reflector case, the main case defining a plurality of holes aligned with different ones of the light emitting elements, on a side of the main case facing the reflector case the main case includes base members at alternating openings of the plurality of holes;
- wherein each one of the plurality of light guides includes a reflective wall, at a split point spaced apart from the inner surface the reflective wall splits into a first split portion and a second split portion of different lengths.
