The present invention relates to artistic lamps such as neon lamps, plasma lamps, and other lamps for special effects or ornamentation.
The history of lighting goes back thousands of years when candles were invented circa 3000 B.C. Later oil lamps were invented and were in use in biblical times. Improvements were made over the centuries, and then the kerosene lamp became popular in the 1800's. Also in that century, electric lighting was invented and developed. It is believed that in 1835, a light bulb based electric lighting system was demonstrated to the citizens of one community; that in 1841 arc-lighting was used as experimental public lighting in Paris, France; that in 1867, Becquerel demonstrated the first fluorescent lamp; and that in 1875 Henry Woodward patented the electric light bulb. Carbon filament or carbon thread incandescent lamps were developed or patented by Thomas Edison and Company in the later 1800's. Neon lamps were displayed at the World Columbian Exposition in Chicago, Ill. in 1893, designed and/or built by the famous Nikola Tesla. Further developments were made in the field of gas discharge lamps in the 1890's, a mercury vapor lamp in 1901, and in 1911, Georges Claude developed the neon lamp. Another fluorescent lamp followed in 1926.
The earliest roots of the neon sign actually date back to 1675 when the noted astronomer Jean Picard observed a faint glow in a mercury barometer tube. When the tube was shaken, a glow called “barometric light” occurred, but it was not then understood that the cause of the light was static electricity. By 1855, however, a German glassblower named Heinrich Geissler developed a Geissler tube in which gas was placed under low pressure. When electrical voltage was applied, the gas glowed. During the 1900's, electric discharge lamps were developed comprising a transparent container having a gas within it that was energized by an applied voltage and thereby made to glow. Neon is one of the gases used for this and is one of the so-called “noble gases” falling within Group VIII of the Periodic Table of the Elements. Those elements comprise helium, neon, argon, krypton, xenon, and radon.
The development of neon lighting has been completely different from the development of incandescent lighting used for home and office general illumination purposes. Neon lamps generally fall into two types, one being the small neon glow lamp, typically drawing power in the range from 0.4 to 3 watts. Those are typically used as indicator lights on electrical devices indicating the presence of voltage and are referred to generally as “neon glow lamps.” The other type is the well-known neon sign which has been used traditionally for commercial purposes. Generally, hollow glass tubes are used to make neon lamps and come in lengths of several feet. The tubes are shaped to fit the purpose: they are frequently shaped into words or depict an object or a company logo for example. Typically, the glass tube is cut, curved and angled, and then put through a process called “bombarding” where the tube is partially evacuated of air, short circuited with high voltage current until the tube reaches a certain temperature, then evacuated further to a certain vacuum level, and then back-filled with argon or neon. Additionally, mercury is injected into the tube. The so-called “neon” lamps can be used to produce numerous different colors. Neon gas itself glows with a characteristic red light, but other colors are available using argon, mercury and phosphors. “Neon tubes” generally refer to positive-column discharge lamps without regard to the specific gas filling. Mercury produces a blue light, carbon dioxide produces white, helium produces gold, and neon produces red. Different colors beyond those are obtained from using phosphor coated tubes. The mercury spectrum produces considerable ultraviolet light which is used to excite a phosphor coating on the inside of the glow tube, and phosphors are available in many different pastel colors. Thus, neon tube bulbs have been used to make fanciful or artistic creations or signage.
Typically, a specific transformer is required and electrodes extending from opposite ends of the lamp tube are connected by wires to the transformer output. One example of a connector for use with a neon lamp is shown in Jung U.S. Pat. No. 5,565,728 entitled “Neon Lamp with Flexible Connectors.” Another neon lamp arrangement is shown in Jung U.S. Pat. No. 5,489,813 entitled “Neon Lamp.” A neon lamp assembly is shown in Chian U.S. Pat. No. 5,504,397 disclosing a neon lamp, a frequency/voltage conversion circuit board for powering the neon lamp, and various other structures. An example of a power supply for a neon lamp is shown in, for example, Nilssen U.S. Pat. No. 5,387,845 entitled “Neon Lamp Power Supply.”
Generally, neon tube lamps of the sort used for signs or ornamentation have not been connected to the same sockets that have been used for normal incandescent lamps used for household lighting having a standard threaded socket. The present invention is directed to providing ornamental and artistic lamps that have a standard threaded base to be inserted into a standard threaded socket of the type used domestically for desk lights, floor lights, and ceiling fixtures used in residences and offices throughout the United States to receive line voltage (120 volts AC) and to operate therefrom.
The present invention has multiple aspects. In one aspect, a lamp assembly is provided with a standard threaded base, a housing for a ballast or other electrical components extending from the threaded base, and a neon tube or other bulb or fixture extending upward (usually) from the housing.
According to further aspect of the invention, such a lamp assembly using preferably a neon tube may further include a backing member that extends upward from the same housing. Preferably the shape of the bulb corresponds in some way with the shape of the backing, and typically they have multiple colors and are not confined to rectilinear shapes. The backing may have different colored areas and may include holographic or reflective fanciful images, line drawings, or other graphic art. Preferably the backing member is displaced a short distance behind the bulb.
In another implementation, an artistic or ornamental object (for example silk flowers or the like) extends upward from the housing together with fiber optic strands that integrate with the other upward extending object.
In a further implementation, a plasma discharge lamp extends upward from the housing. Other artistic lamps can extend from this electrical housing connected to a threaded base member.
Preferred embodiments will now be described with the understanding, however, that the description is merely representative of the embodiments and use various aspects of the present invention. Further, the invention is not confined to the specific embodiments illustrated and described herein. Rather, the scope of the invention is to be determined by the appended claims.

In the illustrated embodiment the upper surface of lid 20 is generally flat. It has a pair of equally sized rings 26 rising up slightly from the surface. The inside diameter of each ring 26 is slightly larger than the diameter of tube 12, and rings 2-6 are preferably spaced along a diameter of the lid 20 at a position to receive the ends of tube 12. Inside of rings 26 are apertures 28 extending completely through lid 20. As best seen in
Housing 16 contains a printed circuit board 40 which supports various electrical components for powering the neon tube 12. Such components may include, illustratively, resistors, diodes, a fuse, various capacitors, including high frequency capacitors, one or more transformers, a magnetic core and windings, and various resistors, all generally represented as electrical components 42. Preferably the discrete electrical components extend downward from printed circuit board 40 and the printed circuit connections are on the upper side of board 40. Preferably an insulating disk 44 made illustratively of paper or any other suitable insulating material is positioned between circuit board 40 (which preferably is circular in plan view) and lid 20. Preferably disk 44 includes an aperture 46 to be aligned with a similar aperture 48 in printed circuit board 40. These apertures allow the circuit board 40 to be placed closer to the lid 20 and fit directly beneath it, adjacent to its underside, without breaking off the glass tip 34.
Main body 22 has an inside diameter slightly larger than the diameter of circuit board 40 and slightly larger than the diameter of downward depending area 36 so that depending portion 36 can be inserted into main body 22 and so that ridge 38 can secure the engagement of these two parts of the housing 16. Main body 22 may have an internal longitudinal ridge 50 extending along its inside circumference near the top of main body 22 and may have generally vertically oriented stiffeners 52 spaced around the internal surface of main body 22.
Threaded base 18 is shown below main body 22. Base 18 includes a central conductor 54 at its lowest point to make electrical contact with a center prong of a standard electrical socket. It also includes a ceramic or other insulator disk 56 to provide electrical insulation between central conductor 54 and the metallic body of threaded base 18, all as customary with standard incandescent light bulbs for domestic use. Electrical wires 58 connect the metallic threaded body and central conductor of base 18 to appropriate circuit points on printed circuit board 40. The electrical circuitry 42 on circuit board 40 provides the necessary voltage, frequency, and current, all as customary for driving a tubular neon bulb, and these are connected to electrodes on tube 12 via wires 60.
A bottom view of housing 16 is shown in
The threaded base 18 and housing 16 can be used for other artistic bulbs also.
Top-hat spacer 82 supports and secures a floral or other arrangement therein with a plurality of several dozen or hundreds of fiber optic strands 84 and an arrangement of flowers 86 and leaves 88.
Preferably the leaves are made of silk or other material. Nylon or other mesh can be used if it is shaped. Illustratively, multiple colors can be used for the flowers, and preferably the leaves are all colored green or various shades of green, although other colors could be used for the leaf substrate. Preferably the fiber optic strands 84 are integrated with the floral arrangement. For example, with reference to
The fiber optic strands can be any suitable material and may comprise, for example, a polypropylene or any other polymeric or other material suitable for fiber optic use. A relatively transparent plastic material is preferred.
While the lamp 10 illustrated in
Thus, it will be appreciated that the fiber optic arrangement of the present invention provides a unique illuminated flower, with edges of leaves and flower petals changing color in accordance with the color changing scheme of LEDs 100. The fiber optic strands are distributed in three dimensions and are integrated into the physical structures that are bound together by the spacer 82. Additional wrapping around the fiber optic strands above the spacer 82 can be provided.
The fiber optic artistic lamps can be used for numerous other three dimensional objects such as a butterfly arrangement shown in
The present arrangement can also extend to a plasma discharge lamp 140, as illustrated in
Another element in
Beneath insulating disk 154 is a substantially circular printed circuit board 158 containing circuitry for powering the plasma lamp. Printed circuit board 158 generally includes discrete circuit elements extending downward from the circuit board with the printed circuit side facing upward, toward the insulating disk 154. In the preferred embodiment, an insulating box 160 encloses various circuit elements and other discrete circuit components 162 are outside box 160. Circuit board 158 includes a hole 154 so that glass tip 152 may extend therethrough without breaking the glass or interfering with the circuit. Extending from circuit board 158 is a drive wire or hot wire 166 that extends upward through a central hole 168 in insulating disk 154 upward through a reentry portion 169 of the globe 142. Within reentry portion 169 is a plastic sheath 170, and wire 166 extends upwards and into that sheath to make contact with a plurality of metal foil spirals 172 situated within sheath 170. The sheath 170 has been broken away in part to show some of the metal foil spirals 172. At the top of sheath 170 is a tip 174 fitted into the reentry portion 169.
Below the printed circuit board 158 with its circuit components 160, 162 is a main body 22 to which the lid 144 connects snuggly as described for the other embodiments. Rather than having a smooth transition region 24 as in the embodiment of
A fourth embodiment of the present invention has a tube lamp (such as neon or other gas discharge or fluorescent) with a reflective or other ornamental backing mounted on the same housing. Preferably the housing connects to a free-standing base and the combination thus described constitutes a free-standing lamp. An embodiment is described using the neon tube lamp assembly shown in
Referring to
Situated behind tube 212 is a placard or backing member 220 which is preferably generally planar and standing generally upright from a mounting block 222 connected to housing 16. Backing member 220 may have a slight angle and may not be perfectly vertical (plumb), that is, it need not be perfectly perpendicular to a top surface of housing 16. Mounting block 222 may comprise a plastic or acrylic block into which the backing 220 is inserted. Mounting block 222 may be fastened by glue or other appropriate means to the top of housing 16. Alternatively, member 220 may be glued or otherwise fastened directly to housing 16.
Backing member or placard 220 may be made of a plastic sheet having graphic features on its front surface. Backing member 220 may have a metallized front sheet adhered to the plastic sheet (or heavy duty cardboard). Alternatively, the graphic features may be printed, painted, or added by any other convenient process. The plastic or other sheet is cut to the desired shape.
The tube 212 in
Preferably neon tube 212 in this embodiment has multiple colors. Preferably the color of neon tube 212 above dividing line 228 is generally white, and it is generally green below dividing line 228. Thus, there can be a general correspondence not only of shape but also of color as between the neon tube 212 and the backing member 220 located behind the curved neon tube.
Preferably the front surface of backing member 220 is reflective also. As a consequence, a reflection of the neon (or other) tube is seen by the viewer along with directly viewing the tube itself.
Preferably the front surface on member 220 includes a pattern of reflective areas or cells 234. Typically cells 234 extend in a rectilinear pattern completely across the front face of member 220.
Housing 16 need have no particular shape, but in the preferred embodiment comprises the cylinder of rotation described above with a generally flat lid 20 and having an inwardly curved portion 24 to provide a transition from the wider body portion of housing 16 to the narrower diameter of the threaded base 18. A top view of lid 20 is shown in
It will be understood that the lamp assembly 210 (of tube 212 with backing member 220) together with base 72 constitutes a lamp that can be placed on a flat surface. Not shown is an electrical A/C cord 74 equipped with an in-line on/off switch, but it will be understood that one is provided (as shown in
The invented combination can be used to form artistic but functional lamps based upon any graphic image or theme. For example, an angel can be simulated by having a line drawing of an angel on backing member 220 with the outer periphery of member 220 corresponding to the silhouette or outer periphery of the angel. On the backing member 220 are lines representing arms, a face, wings, or other desired features. The hair can be colored as desired, illustratively yellow, and the represented garments on the angel can be white or other color(s) as desired. The neon tube 212 corresponds generally to the silhouette shape of the angel and traces out the outer garment or body portion of the angel, the wings, and the head.
A butterfly can be represented as another example. The wings of the butterfly can be colored vividly on the front of member 220, and the shape of member 220 also corresponds to the shape of the butterfly. Likewise, the shape of (preferably neon) tube 212 corresponds to the silhouette of the butterfly and may have any suitable color(s).
As used in this patent specification, the reference to the shape of the tube 212 “corresponding” to the silhouette or outer periphery of the member 220 does not require absolute identity of size but rather only general or approximate correspondence in size and general shape. Indeed it is preferable sometimes for the tube 212 to be slightly smaller than the other silhouette of the backing member 220. Additionally, the tube 212 can be a manmade work product having variations. Thus, a high degree of precision in the outer shapes of tube 212 and backing member 220 is not required, but general similarity of shape is intended.
Alternatively or in addition, the tube 212 may also, in addition to tracing some of the outer silhouette, be shaped to represent some inner features of the object being depicted as, for example, the central disk 224 in the case of the flower shown in
Another example is a holly leaf. For this, the backing member 220 may have multiple colors, principally earth tones, and the (neon) tube may be partially orange and partially another color such as white or green.
A dolphin may be represented using, illustratively, blue neon.
A snowman can be represented using a white neon tube shaped like a snowman wearing a hat, and the backing member can include graphic representations of eyes, a mouth, and garments such as a scarf or the like.
A Christmas tree can be represented having multiple colors, principally green.
Thus it will be appreciated that the shape of tube 212 is usually not rectilinear, i.e., not usually a simple rectangle, but rather corresponds to the (non-rectilinear) outline of a leaf, flower or other plant portion, an animal, a star or other extraterrestrial object, a fictitious character (Santa Claus, Snowman, Easter Bunny, Tooth Fairy, Halloween Witch, etc.) or a supernatural being (e.g., an angel), or other things to be represented.
It will be understood that numerous graphic objects or images, whether natural or supernatural, can be fashioned using this embodiment of the present invention to provide a highly aesthetic lamp with unique features resulting from the synthesis of a neon or other gas tube formed according to various shapes of the item being depicted, in combination with an offset backing member that frequently will have printed or otherwise fashioned on it further elements or the same elements of the item being depicted, typically in more than one color. Preferably, the backing member is reflective and may include a holographic component, thereby adding to the visual impact of the combination. The backing member can also be used with the fiber optic lamp assemblies described with reference to
In all of the embodiments discussed above, the lid and main body are formed of any suitable synthetic or plastic. It will be appreciated that the foregoing description of differing embodiments is illustrative of the wide variety of lamps that can be achieved using aspects of the present invention. While a standard threaded base has been used on various incandescent light bulbs and on fluorescent light bulbs designed to be replacements for incandescent light bulbs, the assemblies described herein offer different choices of artistic bulbs to the consumer market. The scope of the protection to be afforded to the present invention is preferably set forth in the following claims.
