Abstract
An electric incandescent lamp dimming combination fixture device having a subcombination which has at least one thyristor type of semiconductor component, with or without a voltage transient protecting 'G.E. MOV.' type VP varistor, as desired, and with or without a separate selective electric switch or switching means. The combination fixture device having, in at least one of its other embodiments, a subcombination of at least one-half-wave diode rectifier or rectifying means which is an semiconductor member, of the silicon type, with or without a varistor of the zink oxide doped with gallium oxide diode type, or even a diode of the germanium type, as desired, and at least one electrical selectively switching means. At least one of the above subcombinations, for example, being electrically connected in the electrical circuit of substantially at least one portion of the fixture portion of the fixture device so that variable dimming of at least one incandescent lamp and/or at least an 'on' full illumination and/or substantially a 'half-on' or 'half-wave' diode electrical dimming, of at least one incandescent lamp or bulb of and at a hung type of incandescent lamp fixture device dimming combination may be provided as desired. The first and second mentioned subcombinations also providing new and improved utility, by having at least one of the subcombination means electrically connected in the electrical circuit of the electric fixture device between, for example, the source of electric current supply and at least one electric contact member of an electric socket member of an electric incandescent lamp or bulb, or even between the source of an electric current and a, for example, 1, 2 or 3-way electric selective switch or switching means which passes electric current substantially to at least one 1-way, at least two 1-way, or even at least one 3-way incandescent lamp or lamps of the combination fixture device.
