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.
Claims8
A light-projecting device comprising an integral unit of material that is at least translucent, said unit including light-diffusing surfaces, a chamber dimensioned to accommodate a plurality of sources of varicolored light, and reflecting surface disposed at an angle relative to said light diffusing surfaces such as to reflect by means of total internal reflection the light cast from the chamber to said diffusing surfaces which ar textured to cast said light towards the user.
