  • Patent number: 4625152
    Abstract: A tricolor fluorescent lamp operating on a DC power source is disclosed herein. The lamp comprises an outer envelop defining therein a sealed space in which an ionizable medium is filled at low pressure. Disposed within said outer envelop are three tubular envelops of a generally inverted U-shaped configuration which define correspondingly three separate discharge paths and which are coated with respective fluorescent substances emitting different colors. Three sequentially energized anodes are located within the sealed ends of the respective envelops and a common cathode is disposed in adjacently facing relation with the open ends of the envelops, such that the three envelops can be sequentially energized to emit the specific colors which are additively mixed in various proportions to produce a desired color as emitting from the whole lamp.
