Efficacy incandescent light bulbs
First Claim
1. An incandescent light bulb adapted:
- (i) to be used in an ordinary Edison-type lamp socket, (ii) to provide light output in the range between 200 and 2000 Lumens, and (iii) to be powered from the 120 Volt power line voltage normally provided at an ordinary Edison-type lamp socket;
the light bulb comprising;
a screw-base;
(i) having a pair of base terminals, and (ii) being operative to screw into an ordinary Edison-type lamp socket and, by way of the base terminals, to receive the 120 Volt power line voltage provided thereat;
voltage conversion means connected with the base terminals and operative to convert the 120 Volt power line voltage thereat to an output voltage provided at a pair of output terminals, the RMS magnitude of this output voltage being prevented from exceeding a level that is substantially lower than the RMS magnitude of the power line voltage;
incandescent lamp means connected with the output terminals and operative to be properly powered by the output voltage provided therefrom; and
translucent envelope means fastened onto the screw-base and operative to enclose the voltage conversion means and the incandescent lamp means, the envelope means when combined with the screw-base being of size and shape substantially the same as that of an ordinary household incandescent light bulb;
whereby;
(i) the incandescent lamp means is fully and powered by a voltage of RMS magnitude substantially lower than that of the voltage provided at the base terminals, (ii) the light bulb is operative to provide light output in the range between 200 and 2000 Lumens, yet being of size and shape similar to that of an ordinary household incandescent light bulb of substantially the same Lumen output rating.

Abstract
An improved 120 Volt/40 Watt incandescent light bulb is adapted to be used in an ordinary Edison-type lamp socket and provides nearly twice the effective Lumen-output as that of an ordinary 120 Volt light bulb of same power rating and same life expectancy.
The improved light bulb comprises an electronic inverter-type voltage conditioner that provides a voltage of about 15 Volt RMS magnitude to the filament of a small Tungsten-Halogen lamp. This voltage conditioner is comprised within the bottom part of the light bulb and the Tungsten-Halogen lamp is mounted right above the power conditioner--all within an outer envelope.
The improved light bulb has shape and size substantially the same as that of an ordinary household 120 Volt/40 Watt light bulb.
Means are provided by which the Lumen output can be manually adjusted over a wide range.
In one version, the outer envelope is removable and the small Tungsten-Halogen lamp is replaceable.
