Abstract
A portable lamp for providing mixed direct and diffused light. The lamp is especially suited for providing pleasant lighting conditions at a table or workbench. A hollow cover is mounted upon a base. A light bulb inside the cover provides light, the bulb being powered by a self contained power source such as a battery. The cover, which may be spherical, has a translucent upper portion for transmitting diffused light, a medial transparent portion for transmitting undiffused light directly to the tabletop, and an opaque lower portion. A conical shaped reflector within the cover serves to reflect light emitted by the bulb to the translucent and transparent portions of the cover. Colored translucent disks may be removably attached inside the cover to add color to the diffused light.
Claims35
A lamp apparatus comprising:
- a hollow cover defining an interior space, said cover comprising an upper translucent portion, a medial transparent portion, and a lower substantially opaque portion;
- means for mounting a light bulb centrally within said interior space;
- and
- a reflector disposed within said interior space for directing light from said bulb toward said medial transparent portion.
A lamp apparatus for providing direct and diffused lighting, said lamp comprising:
- a hollow globe substantially enclosing an interior space, said globe comprising an upper translucent portion, a medial transparent portion, and a lower opaque portion;
- a light bulb socket located within said interior space;
- and
- a reflector within said interior space and extending radially outward from said socket for directing light from said bulb toward said medial transparent portion.
A lamp apparatus for providing direct and diffused lighting, said lamp comprising:
- a cover comprising a substantially spherical globe at least partially surrounding an interior space, said globe comprising an translucent upper hemisphere, an transparent equatorial band, and an opaque lower hemisphere;
- at least one light bulb socket located centrally within said interior space;
- and
- a substantially frusto-conical reflector within said interior space, said socket located at the apex of the imaginary cone containing said frusto-conical reflector, and said reflector extending radially inward at least partially from the upper edge of said opaque lower hemisphere toward said socket.
