Abstract

A DISPOSABLE POWER SOURCE ADAPTED TO BE DETACHABLY REFLECTING SURFACE WHICH IS A SEGMENT OF A PARABOLIC CYLINDER WHEREIN A LINEAR LIGHT SOURCE IS LOCATED ALONG THE FOCAL AXIS OF THE PARABOLIC CYLINDER AND THE LIGHT EMITTED THEREFROM IS LATERALLY CONTROLLED BY A LAMINAE OF OPTICAL DISCS THAT COLUMNIZE THE LIGHT SUCH THAT THE RAYS ARE DIRECTED ONTO THE REFLECTING SURFACE IN PLANES SUBSTANTIALLY NORMAL TO THE FOCAL AXIS. THE REFLECTED LIGHT RAYS ARE FORWARDLY DISTRIBUTED IN A DESIRED ILLUMINATION PATTERN BY AN OPTICAL LENS LOCATED IN A RECTANGULAR FRONTAL OPENING OF THE HOUSING.

CHARLES FRANC. BY A'lu'onmcY PATENTED JUN28 12m ILLUMINATION UNIT This is a divisional application of application Ser. No. 671,330 filed on Sept. 28, 1967 and now US. Pat. No. 3,522,426, issued Aug. 4, 1970.

SUMMARY OF THE INVENTION In accordance with my invention, my unit comprises a lamp socket having first and second terminals, a lamp in the lamp socket, and a flat battery having first and second terminals. Means connect one battery terminal to one socket terminal. A connector for the battery and socket connects the other socket terminal to the other socket terminal when in one position and disconnects these other terminals when in another position.

BRIEF DESCRIPTION OF THE DRAWINGS In the drawings:

FIGS. 1 and 2 are respectively front and side views of an embodiment of my invention; and

FIGS. 3 and 4 are respectively front and side views of a structure which can be used with the embodiment described above.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Referring now to FIGS. 1-4, a flat vertical sheet 50 having cut out portions 52 and a section 54 which can be swung out horizontally has one surface (except for cut outs) coated with a conductive layer or film. The scoring lines 56 and 58 divide this layer into two electrically separate conductive areas identified at 60 and 62 (slanted line shading). A battery 64 is supported on the sheet with its positive terminal 66 connected to area 60 and its negative terminal 68 connected to area 62. Battery 64 can he slid forward or backward to close or open the circuit. Section 54 has two holes supporting sockets 14, one terminal of each socket being connected via area 60 to terminal 66 and the center portion of 54 being connected both by area 62 to terminal 68 and by fastener 70 to a conductive clip 72 having ends disposed below the other (bottom) terminals of the sockets. When the fastener 70 is secured, clip 72 completes the circuit and energizes the lamps.

FIGS. 3 and 4 show a hollow container 100 having a peripheral lip 102 with an adhesive coating 104 with a removable protective strip 106. The container has compartments which can be shaped to receive the unit described above. Then the strips can be removed and the entire container with inserted unit can be secured to a card, ornament or package for use. Tilting the card vertically will cause battery 64 to slide downward to engage contacts 66 and 68 to light up the unit. Likewise, tilting the card back will turn off the light. Other securing means, pins and the like can be used instead of coating 104.

In the FIGS., the dotted circle indicates a reflector 23 which can be used. The batteries shown can be used to operate more than two lamps if desired, and all supports can be modified to accommodate more than two lamps.

While I have described my invention with particular reference to the drawings, my protection is to be limited only by the terms of the claims which follow.

Iclaim:

I. A disposable illumination apparatus for detachable.

terminals to said lamp socket means'and a second conductive layer disposed ad acent to and electrically insulated from said first conductive layer for electrically coupling to said other battery terminal so that by slidably positioning said battery against said conductive layers, current is caused to flow in said miniature lamp.

2. The illumination apparatus as recited in claim 1, wherein said lamp socket means comprises an elongated flat bracket secured to said housing and electrically conductive with said first and second conductive layers.

3. The illumination unit as recited in claim I additionally comprising lamp reflectors secured to said housing adjacent to each of said lamps.

4. The illumination unit as recited in claim 1 additionally comprising;

a hollow container having a compartment for receiving said housing, and

means disposed on said container for securing the container and housing to a flat surface.

5. The illumination unit as recited in claim 4 wherein said securing means comprises a pressure sensitive adhesive.
