INDICATOR WITH CONICAL STRUCTURE FOR REDUCING DISTORTION OF LIGHT

摘要

PURPOSE: An indicator is provided to reduce distortion of light by permitting the indicator to have a conical structure and concentrating the path of light to a focusing unit. CONSTITUTION: An indicator comprises an insertion portion where a knob assembly(20) is inserted; a flange portion formed along the circumference of the insertion portion and coupled to a panel(22); a conical portion protruded downward in opposition to the insertion portion; a light diffusion portion formed in the conical portion such that the light diffusion portion contacts the bottom of the insertion portion; and a light focusing portion formed at the apex of the conical portion in opposition to the light diffusion portion.
