Study on Construction of ZLL Reflectors

ZLL medium membranoe reflector, the wide of its firing area is determined by the size of reflectors' quadric and curvature and by its arrangement of small ladder-shaped surfaces. In this article, we adopt computer analogue method, making illuminant pass to the reflect surface, then from the reflect surface to the light-sensitive surface. The beam passing quantity may reach maxinum, we can adjust cur curvature, angle of incidence and the position of illuminant to get the designed satisfactory lighting condition.
