Abstract
A light-projection device for digital instrumentation consists of a one-piece body including reflective and diffusive surfaces and a chamber to locate a plurality of sources of varicolored light. Light from the sources is diffused to fill an entire line segment of the seven in a typical digit, with varicolored sources of light affording the potential for polychromatic display, thus enhancing the data with color to signify danger, normality, negative values, et cetera.
