Abstract
A vapor-generating electric lamp includes a sealed lamp envelop having a concave depression therein, an incandescent filament mounted within the lamp envelope, a lamp base, and a replaceable, solid insert in the concave depression. The insert produces a scent when it is warmed by heat from the filament. Preferably, the insert is a polyamide impregnated with a scent and includes a portion that matches the shape of the depression in the lamp envelope. The depression for holding the insert is preferably located at the opposite end of the lamp from the base. When the lamp is used in a base-down orientation, the insert is held in the depression by gravity.
