Illuminated indicator gauge.

摘要

An indicator gauge is disclosed, which comprises a housing; a dial board installed in the housing; and a pointer arranged in such a manner that an elongate pointing portion moves over a front face of the dial board. A fluorescent substance is deposited on a longitudinally extending limted part of the pointing portion, which substance emits visible light when receiving ultraviolet rays. An ultraviolet lamp is arranged in front of the dial board and the pointer to excite and thus cause the fluorescent part of the pointer to emit visible light.
