Abstract:
A light bulb assembly having a light bulb with the ability to change color. The light bulb assembly comprises a light bulb, a socket for containment of the light bulb, and a light switch assembly for selectively providing current to the socket and attached light bulb. The light bulb has three filaments which separately emit white light upon selective illumination. Two of the filaments, however, are separately encased by a sleeve of translucent, differently colored material. Accordingly, the white light emitted by each of the latter two filaments is filtered by the colored sleeves, and these filaments thereby produce colored light. The switch assembly has three switches, each of which selectively illuminates one of the filaments. The light bulb assembly is thereby able to selectively provide white light as well as differently colored light on different occasions.
Abstract:
There is provided an electric current utilising facility conventionally connectable to an electric current supply outlet for causing the diversion of current along a desired circuit in response to manipulation of the facility. One embodiment of an electric current utilising facility is in the form of a re-usable light bulb (10). The bulb (10) comprises a circuit carrying device in the form of a globe (12) fitted with a number of independent filament circuits (14), and a circuit selecting mechanism providing a swivellable member firmly securable to a matchingly formed current supply outlet as provided by a sleeve (16) which snugly but freely swivellably in the direction of arrow (17) sits onto the stem (18) of the globe (12) while being retained against slipping owing to the stem (18) providing a ridge (20) on its socket engaging side. The sleeve (16) is fitted with pins (22) enabling the bayonet coupling engagement of the bulb (10) to a conventional light bulb socket outlet.
