Abstract

An illuminated revolving lamp device having a rotating translucent member surrounding a source of light and bearing colored patterns thereon, and a second translucent member formed with grating portions of various transmissiveness, the second translucent member adjacent first translucent member such that when the display device is viewed from a fixed location, a changing display of colors and shapes is observed.

Claims

1. An illuminated rotating lamp device comprising:

a base;

a source of illumination supported on said base;

a first translucent member supported on said base, said first translucent member having a pattern formed thereon;

a second translucent member supported on said base with portions of various transmissiveness; and

a drive system for moving said first translucent member with respect to said second translucent member, whereby the illumination from said source of illumination as observed through said second translucent member is a varying pattern of shapes depending upon the relative positions of said first and second translucent members with respect to each other.

2. The illuminated rotating lamp device of claim 1, wherein said first and second translucent members are of a generally cylindrical shape, with said second translucent member being of a larger diameter than the first translucent member.

3. The illuminated rotating lamp device of claim 1, wherein said first and second translucent members are of a frustum shape, with said second translucent member being of a larger diameter than the first translucent member.

4. The illuminated rotating lamp device of claim 1, wherein said first translucent member has a pattern formed thereon of at least two different colors.

5. The illuminated rotating lamp device of claim 1, wherein one of said first and second translucent members has a pattern formed thereon by two transparent colored portions and a clear portion, with portions of said two colors overlying each other.

6. The illuminated rotating lamp device of claim 1, wherein said translucent members are formed of transparent colorless base, with said pattern of colors being applied thereto.

7. The illuminated rotating lamp device of claim 1, wherein a first end of said second translucent member is supported on said base, and a cover is secured to a second end of said second translucent member.

8. The illuminated rotating lamp of claim 1, wherein said drive system causes said first translucent member to move in a first direction relative to the base.

9. The illuminated rotating lamp device of claim 8, wherein said drive system includes first and second counter rotating gears and a first turntable for supporting said first translucent member for relative rotation with the base.

10. The illuminated rotating lamp device of claim 1, wherein said source of illumination is electrically energized.

11. An illuminated rotating lamp device comprising:

a base;

a drive system;

an illumination;

a first translucent member having portions of different indicia around said illumination source; and

a second translucent member adjacent said first translucent member, said second translucent member having portions through which said illumination passes, said drive system causing said first translucent member to move with respect to said second translucent member, whereby the color and pattern of the illumination emitted through said second translucent member is of a changing appearance when observed from a fixed position spaced from the lamp.

12. The illuminated rotating lamp device of claim 11, wherein said first and second translucent members are of a generally cylindrical shape, with said second translucent member being of a larger diameter than the first translucent member.

13. The illuminated rotating lamp device of claim 11, wherein said first and second translucent members are of a frustum shape, with said second translucent member being of a larger diameter than the first translucent member.

14. The illuminated rotating lamp device of claim 11, wherein said first translucent member has a pattern formed thereon of at least two different colors.

15. The illuminated rotating lamp device of claim 11, wherein one of said first and second translucent members has a pattern formed thereon by two transparent colored portions and a clear portion, with portions of said two colors overlying each other.

16. The illuminated rotating lamp device of claim 11, wherein said translucent members are formed of transparent colorless base, with said pattern of colors being applied thereto.

17. The illuminated rotating lamp device of claim 11, wherein a first end of said second translucent member is supported on said base, and a cover is secured to a second end of said second translucent member.

18. The illuminated rotating lamp of claim 11, wherein said drive system causes said first translucent member to move in a first direction relative to the base.

19. The illuminated rotating lamp device of claim 11, wherein said drive system includes first and second counter rotating gears driving a first turntable for supporting said first translucent member for relative rotation with the base.

20. The illuminated rotating lamp device of claim 11, wherein said source of illumination is electrically energized.

21. A motion lamp comprising:

a base;

a drive system on the base;

an illumination source supported on said base;

a first translucent member having portions of different, related indicia supported on said base; and

a second translucent member adjacent said first translucent member and supported on said base, said second translucent member having complimentary portions through which said illumination passes, said drive system causing said first translucent member to move with respect to said second translucent member, whereby a pattern of the illumination emitted through said second translucent member is of a changing effect when observed from a fixed position spaced from the lamp.
