Abstract

A lighting unit including a hollow hemispherical body, a hemispherical holder, and a sphere. A center of a bottom half of the hollow hemispherical body contains the hemispherical holder which is configured to hold the sphere. The sphere includes a light source, a translucent portion, and an opaque portion. The light source is disposed inside of the sphere, and the sphere is configured to rotate within the hemispherical holder so as to vary a position of light emitted by the light source through the translucent portion.

First claim

1 . A lighting unit, comprising:
a hollow hemispherical body; a hemispherical holder; and a sphere, wherein a center of a bottom half of the hollow hemispherical body comprises the hemispherical holder which is configured to hold the sphere, wherein the sphere comprises:
a light source;
a translucent portion; and
an opaque portion,
wherein the light source is disposed inside of the sphere, wherein the sphere is configured to rotate within the hemispherical holder so as to vary a position of light emitted by the light source through the translucent portion, and wherein the hemispherical holder is connected to the hollow hemispherical body by a shelf so as to cover an entirety of the bottom half of the hollow hemispherical body, and wherein the shelf fills a space between the hollow hemispherical body and the hemispherical holder such that there is no gap between the hollow hemispherical body and the hemispherical holder.

2 . The lighting unit of claim 1 , wherein a portion of a perimeter of the bottom half of the hollow hemispherical body is flat and configured to be placed on a surface.

3 . The lighting unit of claim 1 , wherein a portion of the hemispherical holder protrudes from the hollow hemispherical body.

4 . The lighting unit of claim 1 , wherein half of the hemispherical holder protrudes from the hollow hemispherical body.

5 . The lighting unit of claim 1 , wherein the hemispherical holder comprises a rod disposed across a diameter parallel to the hollow hemispherical body upon which the sphere rotates horizontally.

6 . The lighting unit of claim 1 , wherein the hemispherical holder comprises a rod disposed across a diameter perpendicular to the hollow hemispherical body upon which the sphere rotates horizontally.

7 . The lighting unit of claim 1 , wherein the hemispherical holder comprises a rod disposed vertically from a bottom of the hemispherical holder upon which the sphere rotates vertically.

8 . (canceled)

9 . The lighting unit of claim 1 , wherein at least one of the hemispherical holder and the hollow hemispherical body is made of an opaque material.

10 . The lighting unit of claim 9 , wherein the opaque material is selected from metal, wood, cement, porcelain, ceramic, and plastic.

11 . The lighting unit of claim 1 , wherein the translucent portion is 1-99% of a surface area of the sphere.

12 . The lighting unit of claim 1 , wherein the translucent portion is at least one color selected from white, red, green, blue, yellow, pink, purple or orange.

13 . The lighting unit of claim 1 , wherein the translucent portion is operably interchangeable so as to change a property of the light emitted by the light source through the translucent portion.

14 . The lighting unit of claim 1 , wherein the translucent portion of the sphere is made of a material selected from glass, plastic, and fabric.

15 . The lighting unit of claim 1 , wherein the opaque portion of the sphere is made of a material selected from metal, wood, cement, porcelain, ceramic, and plastic.

16 . The lighting unit of claim 1 , wherein the lighting unit is electrically connected to a power source so as to power the light source.

17 . The lighting unit of claim 16 , wherein the power source is a battery or an electrical outlet.

18 . The lighting unit of claim 1 , wherein the light source is motion, sound, or mechanically activated.

19 . The lighting unit of claim 1 , wherein the light source is selected from incandescent, compact fluorescent (CFL), halogen, and light-emitting diode (LED).
