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.
