摘要： The invention is related to a reflector lamp comprising a parabolic primary reflecting section, a parabolic or spheric secondary reflecting section joined to the primary reflecting section, a parabolic or spheric tertiary reflecting section joined to the secondary reflecting section, and an incandescent or discharge light source. The secondary and tertiary reflecting sections have faceted surfaces which longitudinally extend along the surface thereof so that most (at least 50%) or substantially all the light reflected by the faceted surfaces avoids the light source and thus the light, which would be absorbed or scattered by the light source, is minimized or substantially eliminated.

摘要： A jacketed metal halide discharge lamp combining a miniature arc tube containing sodium iodide and a standby filament within an outer envelope, is provided with a glass sleeve around the arc tube. The glass sleeve is preferably connected to a point of potential which is positive relative to the arc tube, suitably the anode when the arc is operated on d.c. The glass sleeve prevents sodium loss from the arc by trapping ultraviolet light and by shielding the arc from photoelectrons. The sleeve serves also to reduce color shift when the arc tube is switched over from "high" to "low", and to protect the outer bulb in the event of arc tube rupture.
