Abstract

852,867. Fluorescent discharge lamps. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 6, 1959 [Aug. 9, 1958], No. 26917/59. Class 39(1). The layer of luminescent material e.g. a manganese and antimony-activated calcium fluorochlorophosphate on the inner side of the glass envelope of a discharge lamp contains barium tetraphosphate as an adhesive. The phosphor may be mixed also with nitrocellulose as a binder.
