Abstract
A light reflector system for an elongated light source and having multiple reflective surfaces, some of which are treated for diffusing light, particularly those surfaces that reflect light at low reflective angles, and some of which are specular or, alternatively, treated for light spread reflection, particularly those surfaces that reflect the image of the lamp source at high reflective angles.
