Illuminating light blending makeup mirrors and electrical control circuit

Claim 1

An appliance comprising: a. a casing having a mirror connected thereto which is adapted for use as a makeup mirror, and an electrically energizable circuit connected to the casing and adapted to be electrically conNected to a source of supply of A.C. power having an alternating current output voltage; b. the circuit including first and second incandescent light sources electrically connected in a series combination with one another, the series combination being electrically connected across the source of A.C. power when the circuit is connected to the source, the light sources having the same voltage ratings but different wattage ratings, the wattage rating of the second light source being higher than that of the first light source; c. the circuit also including non-linear impedance means electrically connected across said first light source and adapted to short-circuit said first light source a predetermined time interval during each half cycle of source output voltage, the non-linear impedance means including a bidirectional gate controlled thyristor electrically connected in parallel with said first light source and having electrically connected thereacross a variable resistor and capacitor electrically connected in series with one another, said thyristor having a gate terminal, said series connected variable resistor and capacitor having an electrically common connection therebetween, and the non-linear impedance means including a triggering diode electrically connected between the gate terminal of the thyristor and the common connection between the series connected variable resistor and capacitor; d. a filter associated with at least one of said light sources and adapted to provide for the light from the respective sources to have different spectral characteristics; and e. means for manually varying the resistance of said variable resistor for varying said short-circuit time interval so as to increase the amount of power supplied to one of said light sources and decreases the amount of power supplied to the other of said light sources, whereby light contributed by each of said sources to the combined light from said sources may be suitably adjusted for use with said mirror as a makeup mirror.
