Abstract
A wide-dispersion indirect lamp assembly with an elongated lamp housing (14), symmetric to a central, vertical plane (26), and which prevents at least most of the light from escaping downward. The assembly includes two fluorescent tubes (28); and a reflector (30) above each of the tubes. Each reflector, seen in vertical cross section, slants upward and away from a point (32) on the upper half of the circumference of the fluorescent tube. The point (32) is preferably shifted away from the apex line (34) of the circumference of the fluorescent tube toward the central plane (26) of the lamp housing (14).
