Abstract
Abstract An aroma disc usable in conjunction with a conventional table lamp whose light bulb socket has a harp secured thereto to support a lampshade, the harp being provided with an upwardly projecting bolt on which is received the center collar of the lampshade spider. The aroma disc includes a round pad of porous material impregnated with a liquid fragrance, the pad being sandwiched between two round plies of reflective metal which are peripherally joined together and are provided with a center hole to accommodate the harp bolt whereby when the disc is installed on the lamp it is placed above the bulb. Concentric with the center hole on each ply of the disc is a circular array of openings which define ports to expose the pad. When the lamp is turned on, heated air currents arising from the bulb penetrate the ports and pass through the pad to volatilize the liquid fragrance, thereby generating an aromatic vapor which suffuses the room illuminated by the lamp.
