Reflector for a linear light source and louvre controller incorporating the same

摘要

A louvre controller for a linear light source has plural transverse reflectors 33 and each located between side reflectors 31, 32. The transverse reflectors have arcuate surfaces forming a double concave reflector and a base 38 of the transverse reflectors is profiled to provide predetermined vertical cut-off angles for all horizontal angles of azimuth.
