Embodiment Construction
[0039] Referring now in detail to the drawings, and initially to FIG. 1, there is shown one transparent light emitting member 1 of the present invention in the shape of an elongated rod 2 having a pattern of notches or grooves 3 in a surface 4 of the member for causing light that is transmitted through the member by internal reflection to be reflected or refracted out of the member as well known in the art. However, the notches or grooves 3 of the present invention, rather than being relatively sharp grooves as is conventional practice, are rounded shallow notches or grooves each having a generally U or C cross-sectional shape as schematically shown in FIG. 2. These rounded notches or grooves 3 may have a minimum depth and width of radius of no more than a few thousandths of an inch, depending on the length and thickness of the light emitting member, and have the advantage that they will scatter the light more finely than sharp grooves and will reduce the risk of breakage of the mem...
