Abstract

A lighted display device which may be of either the EL or LED type. In the EL embodiment, an EL sheet may be positioned on an upper surface of a driver, and removably secured thereto with an outer snap ring. This configuration would permit changing out of an EL sheet, while still retaining the other device components. In one embodiment, the device utilizes a touch switch, so that illumination will occur when a user touches the EL sheet in proximity to the switch. In another embodiment, the device utilizes a motion sensor, so that movement in proximity to the device will cause illumination.

Claims

1. A lighted display device comprising:

a driver having an upper surface and a bottom surface and a source of power;

an EL sheet adapted to be positioned on the upper surface of the driver;

wherein the EL sheet is in electrical contact with the driver; and

an outer snapping ring adapted to be positioned around a peripheral area of the EL sheet and to removably secure the EL sheet to the driver.

2. The lighted display device of claim 1, further comprising a back attaching ring having an upper surface and a bottom surface adapted to be removably coupled to the driver, with the bottom surface of the driver facing the upper surface of the back attaching ring.

3. The lighted display device of claim 1 wherein the source of power is in a battery case projecting outward from the bottom surface of the driver.

4. The lighted display device of claim 3 wherein the back attaching ring includes a battery case passage in a central area thereof, dimensioned to permit passage therethrough of at least a portion of the battery case.

5. The lighted display device of claim 4, further comprising springs projecting upward from the upper surface of the back attaching ring, wherein the springs are adapted to flex when the back attaching ring is coupled to the driver.

6. The lighted display device of claim 4, further comprising:

at least two alignment pin openings on the back attaching ring;

at least two tab openings on the back attaching ring;

at least two alignment pins projecting from the bottom surface of the driver; and

at least two tabs projecting from the bottom surface of the driver;

wherein the at least two alignment pins are adapted to be inserted into the at least two alignment pin openings when the back attaching ring and the driver are coupled together;

wherein the at least two tabs are adapted to be inserted into the at least two tab openings when the back attaching ring and the driver are coupled together.

7. The lighted display device of claim 1 further comprising a switch controlling transmission of an electrical signal from the source of power to the EL sheet and wherein the switch is a touch switch.

8. The lighted display device of claim 1 further comprising a switch controlling transmission of an electrical signal from the source of power to the EL sheet and wherein the switch is coupled to a motion sensor and is activated by motion in proximity to the lighted display device.

9. The lighted display device of claim 1 further comprising a switch controlling transmission of an electrical signal from the source of power to the EL sheet and wherein the switch is coupled to an ambient light sensor and is activated when ambient light reaches a predetermined level.

10. A lighted display device comprising:

a driver having an upper surface and a bottom surface and a source of power;

an EL sheet adapted to be positioned on the upper surface of the driver;

wherein the EL sheet is in electrical contact with the driver; and

a switch controlling transmission of an electrical signal from the source of power to the EL sheet;

wherein the switch is a touch switch.

11. The lighted display device of claim 10, further comprising a back attaching ring having an upper surface and a bottom surface adapted to be removably coupled to the driver, with the bottom surface of the driver facing the upper surface of the back attaching ring.

12. The lighted display device of claim 10 wherein the source of power is in a battery case projecting outward from the bottom surface of the driver.

13. The lighted display device of claim 12 wherein the back attaching ring includes a battery case passage in a central area thereof, dimensioned to permit passage therethrough of at least a portion of the battery case.

14. The lighted display device of claim 13, further comprising springs projecting upward from the upper surface of the back attaching ring, wherein the springs are adapted to flex when the back attaching ring is coupled to the driver.

15. The lighted display device of claim 13, further comprising:

at least two alignment pin openings on the back attaching ring;

at least two tab openings on the back attaching ring;

at least two alignment pins projecting from the bottom surface of the driver; and

at least two tabs projecting from the bottom surface of the driver;

wherein the at least two alignment pins are adapted to be inserted into the at least two alignment pin openings when the back attaching ring and the driver are coupled together;

wherein the at least two tabs are adapted to be inserted into the at least two tab openings when the back attaching ring and the driver are coupled together.

16. A method for altering the appearance of a lighted display device comprising:

utilizing a lighted display comprising;

a driver having an upper surface and a bottom surface and a source of power;

an EL sheet adapted to be positioned on the upper surface of the driver;

wherein the EL sheet is in electrical contact with the driver; and

an outer snapping ring adapted to be positioned around a peripheral area of the EL sheet and to removably secure the EL sheet to the driver;

positioning a first EL sheet having a first appearance on the upper surface of the driver;

snapping the outer snapping ring in position around a peripheral area of the first EL sheet and the driver;

supplying an electrical signal from the source of power to the first EL sheet;

removing the outer snapping ring;

removing the first EL sheet;

positioning a second EL sheet having a second appearance on the upper surface of the driver;

snapping the outer snapping ring in position around a peripheral area of the second EL sheet and the driver; and

supplying an electrical signal from the source of power to the first EL sheet.

17. The method of claim 16 wherein the lighted display device further comprises a switch controlling transmission of an electrical signal from the source of power to the EL sheet and wherein the switch is coupled to a motion sensor and is activated by motion in proximity to the lighted display device and further comprising positioning the lighted display device so as to facilitate activation of the switch by motion in proximity to the lighted display device.

18. The method of claim 16 wherein the first appearance and the second appearance each contain product advertisement information.
