A line-of-light illuminating device includes an optical lightpipe for receiving and transmitting light by internal reflection and an integral optical lens located at an emission portion of the lightpipe for focusing the reflected light into a collimated line-of-light beam. The lightpipe and lens are preferably injection molded in a single shot as a unitary device. The lightpipe preferably has an isosceles triangular cross-sectional shape with an apex formed at the point where the two equilateral sides join. A reflective surface is formed along the apex on the emission portion of the lightpipe, and the lens is located on the side opposite the apex. The internally reflected light striking the reflective surface is reflected perpendicularly therefrom to the lens. The lens focusses the reflected light into the collimated line-of-light beam.
