, 1 mix SHADE This invention relatesin general to lamp shades, and in particular, to a wax or wax appearing plastic shade or shell placed, shell like, on a supporting surface over a heat generating light source. The material of the shade or shell includes a scent substance subject to slow release with heating from the light source.
Many different objects have been used in table centerpiece arrangements, on fireplace mantels, and on other supporting surfaces in attaining desired decorative scenes. An internal glow through wax, or wax appearing plastic in the form of a shade or shell is placed on a supporting surface over a light source giving-internal illumination to the shade or shell. Imagine, if you will, how much more effective such a shade or shell would be with internal illumination if scent material impregnated within the wax or plastic would be slowly released by heat from the light source. An aesthetically pleasing fragrance so released would accentuate the attractiveness of such shades or shells as mood lamps.
It is therefore a principal object of this invention to provide an aesthetically pleasing shade or shell positionable over a light source on a supporting surface with the shade or shell having an internal glow from the light source.
A further object is for material of the shade or shell to be wax or wax-like appearing plastic translucent to passage of light from an 'intemal light source.
' Still another object is for the wax or wax appearing material of the shade or shell to be impregnated with scent deriving material subject to slow release with moderate heating from an internal light source.
Features of the invention useful in accomplishing the above objects include, in a shade or shell of translucent material such as wax or wax-like appearing plastic, a shade or shell shaped to be positioned over and enclose an internal light source. The light source could be a light bulb that radiates heat as well as light when turned on. Further, the shade or shell material may have a natural scent giving a pleasant aroma or pleasing fragrance may be provided by a scent deriving material impregnated through the wax or plastic of the shade or shell. The shade or shell is sized and shaped for such impingement of heat from the internal light source as to attain a desired slow release of scent material from the shade or shell material to the atmosphere for a pleasing fragrance.
Specific embodiments representing what are presently regarded as the best modes of carrying out the invention are illustrated in the accompanying drawing.
In the drawing:
FIG. 1 represents a top plan view of a shade or shell of wax or wax-like appearing plastic with translucent walls;
FIG. 2, a cut away and sectioned side elevation view taken along line 2--2 of FIG. 1 with the shade placed on a supporting surface and enclosing a light source also placed on the supporting surface;
FIG. 3, a top plan view of a hemispherically shaped shade or shell; and,
FIG. 4, a cut away and sectioned side elevation view taken along line 4-4 of FIG. 3 with the shade or shell placed on a supporting surface and enclosing a light source also placed on the supporting surface.
Referring to the drawing:
The shade (or shell) 10 of FIGS. 1 and 2 is shown to be a hollow truncated pyramid with four sloping translucent material side walls 11, l2, l3 and 14 with bot tom edges resting on a supporting surface 15. The side walls are terminated at the top in top surface wall 16 with the side and top walls enclosing a cavity volume of adequate size to contain a light source 17, in the form of a light bulb on a self contained battery power pack assembly 18 also placed on the supporting surface 15. The translucent material of the shade is wax or plastic with a pleasant natural scent or impregnated with a scent material subject to slow release with moderate heating for obtaining a desired pleasing fragrance as the shade is used with the internal light source 17 turned on. The bulb used as light source 17 is such as to generate the required moderate heating of the shade walls for slow release of scent material. Obviously, the shade walls should be so spaced from the light source as to attain sufficient heating therefrom for scent material release in providing the desired fragrance. The top wall 16 is provided with an opening 19 in order that scent material released inside the shade 10 may flow out to the atmosphere. Please note that light bulb 17 may be on a pedestal in place of power pack assembly 18 with power wires extended to an external power supply (detail not shown).
The shade or shell 20 of FIGS. 3 and 4 is in the form of a hollow hemispherical translucent wall 21 of wax or plastic having a circular lower edge 22 resting on a supporting surface 23. The lamp bulb 17 of a power pack assembly 18', also resting on supporting surface 23, supplies internal illumination to the shell 20 in developing an aesthetically pleasing glow through translucent wall 21. An opening such as opening 19 of the embodiment of FIGS. 1 and 2 may be provided with the embodiment of FIGS. 3 and 4, however, with some embodiments there is sufficient heating of the translucent wall to achieve slow release of scent material directly to the atmosphere from the outer surfaces of a shell wall. The wax or plastic of translucent wall 21 either has a pleasant natural scent or is purposely impregnated with scent material for slow release with moderate heating from lamp bulb 17' in developing a pleasing fragrance as the bulb is on and the shell or shade 20 is illuminated.
Whereas this invention is illustrated and described with respect to a plurality of embodiments thereof, it should be realized that various changes may be made without departing from the essential contributions to the art made by the teachings hereof I claim:
1. In a shade shaped for internal illumination: translucent material walling shaped with side and top wall sections to enclose a volume and having bottom edge means that rests on a supporting surface, said translucent material being impregnated with a scent material subject to slow vaporizing release with moderate heating; said volume enclosed by said side and top wall sections being of sufficient size and shape to enclose a light source structure also resting on the supporting surface in contact with said bottom edge means when supporting the shade.
2. The shade of claim 1, wherein said translucent material walling is wax.
3. The shade of claim 1, wherein said translucent material walling is porous plastic material.
7. In a shade adapted for internal illumination: translucent walling of scent substance impregnated material having bottom edge means that rests on a supporting surface; and with the volume enclosed by said translucent walling being of sufficient size and shape to enclose acombined light source and heat generating SllUCtUl'.
