Description

July 19, 1955 w. v. ETZKORN 2,713,629

LUMINOUS BODIES Filed Sept. 5, 1950 INVENTOR. h/a/fer V. E 7zkor/ ATTORNEY United States Patent 2,713,629 LUMINOUS BODEES Walter V. Etzkorn, Qakland, Calif. Application September 5, 1950, Serial No. 183,186 9 Claims. (Cl. 240-2.25)

that may be readily bent to form various shapes such as letters and other characters in advertising display and other uses.

More particularly, similar elongated structure made of plastic or any other suitable flexible and in such a manner that they may be marketed in long units adapted for rolling on large spools to be cut into It is further proposed, in the present invention, to incorporate in such tubes or structures a certain amount of fluorescent material, which may be applied in the form of a coating to the inside or the outside of the tube or other structure, or sandwiched within layers, or may be embedded in the material thereof, and which will be excited to glow by ultraviolet rays emitted from the luminous gas in the ampo'ules.

The present invention is agents for rendering the lumlnous gas active for illumination, in the present invention it is proposed to provide a luminous tube of the character described that is adapted for connection to ordinary A. C. or D. C. systems.

Further objects and advantages of my invention will appear as the specification proceeds, and the novel features of my invention will be fully defined in the claims attached hereto.

The preferred forms of my invention are illustrated in the accompanying drawing, in which:

Figure 1 shows a side view on an enlarged scale of my luminous tube, a portion being broken away to disclose the interior construction,

Figure 2, a detail view of a glow lamp used in my construction,

Figure 3, a detail view, in section, of a modified form of glow lamp used in my construction,

Figure 4, a side view, partly in section, of a modified form of my luminous tube, and

Figure 5, a sectional detail view of a slightly modified form of a glow lamp used in the structure of Figure 4.

While I have shown only the preferred forms of my invention, I wish to have it understood that various 2,7l3,629 Patented July 19, 1955 mately one-half inch proximately inch in thickness.

The inner wall of the tube is shown as provided with a coating 3 of phosphor or other fluorescent material. This coating may be applied to the outside, or the entire body of plastic material may be impregnated with fluorescent material, or the fluorescent material may be sandwiched between layers of the flexible body.

The lamps 2 may be of any suitable shape and character suited for the purpose and are here shown as commercial neon glow lamps comprising a glass wall or envelope 4, a pair of spaced electrodes 5 and a pair of connecting wires 6 sealed in the base 7 of the lamp. The envelope 4 is filled with a luminous gas.

The lamps are carried by two conducting wires 8 which extend lengthwise through the tube, preferably in manner as at 9. The lamps and the conducting wires thus form a chain which may be drawn through the tube into any position desired and which will retain the posiadjusted due to the flexibility of the chain, which allows numerous portions thereof to enter into frictional contact with the inner face of the tube, particularly as the latter is bent and flexed into shape to present a desired character.

Each of the lamps has a resistance, impedance, reactance or capacitor It) incorporated in one of the lead wires thereof, or within the lamp itself. The two main conducting wires 8 may be connected to a suitable shown) adapted for connection into any suitable socket Without exposing The lamps are also sufliciently short, as compared with the length of the tube and sufli- While normally most letters and characters in advertising signs are formed on large curves as compared with a tube one-half inch in diam- Furthermore, this flexible tubing can be brought up to an inflection point and crimped, a feat which would not be possible in the luminous tube trade.

While I do not desire to limit myself to specific dimensions, I might say that in my working model I employ ampoules about inch in diameter and one inch in length, with inch spacing between the ampoules.

Where plain plastic material is used for the tube, the

lamps, when lit, will show up as spaced sources of light, sufficiently close, however, to deflne the outline of the tube. if a more uniform glow following the length of the tube is desired, the fluorescent material is added to the tube, as at 3. This material will be excited to glow by ultraviolet rays emitted from the luminous gas in the ampoulcs and to spread the lighting effect over the entire tube.

In case it is desired to use quartz glass, or other ultraviolet transmitting glass or material, for the ampoules for more effective emission of ultraviolet rays, the structure shown in Figure 3 may be used. Quartz glass does not lend itself to scaling over lead-in wires and it is desirable therefore to make the ampoule 2 in three parts, a main body portion 11 for holding the luminous gas made of quartz glass, a base 12 of ordinary glass having the lead wires 13 embedded therein and a seal 14 between the main body portion and the base.

In this form the resistor or condenser is made by printing or painting a small section of the ampoule, as at 15,

the print or paint being connected into one of the lead wires as shown.

The form shown in Figures 4 and 5 is substantially similar to the form previously described, except that spherical lamps 2" are substituted for the ampoules, the electrodes being suitably connected into the lamps as shown at to. in the form of Figure 4 the resistors 10 are shown in conventional form, while in Figure 5 a printed or painted surface section is substituted as at 15.

While my flexible luminous body has been described as comprising a flexible hollow tube and a relatively independent chain of lamps and accessories adapted for mounting in the tube, various modifications may be made embodying the principle of the invention.

I claim:

1. A luminous body comprising a flexible tube of light transmitting material adapted for bending into a desired shape, and a chain of electrical lamps extending through the tube, the chain comprising a pair of spaced conductors arranged in diametrically opposed relation within the tube, pairs of lead wires extending from the conductors toward one another, and lamps secured upon the lead wires and supported thereby substantially in central relation with respect to the tube, and the lamps being of a width substantially equal to one-half of the tube diameter and being spaced along the length of the tube sufficiently close to substantially illuminate the entire tube area.

2. A luminous body comprising transmitting material adapted for shape, and a chain of electrical lamps extending through the tube, the chain comprising a pair of spaced conductors arranged in diametrically opposed relation within the tube, pairs of lead wires extending from the conductors toward one another, and lamps secured upon the lead wires and supported thereby substantially in central relation with respect to the tube, and the lamps being of a width substantially equal to one-half of the tube diameter and being spaced along the length of the tube sulficiently close to substantially illuminate the entire tube area, and the tube having fluorescent material incorporated in the wall thereof to cause the entire wall of the tube to glow in response to light rays emitted by the lamps.
