Abstract

A poly night light is made of an un-saturated polyester resin (UPR) compound to provide the night light with a certain degree of softness and cushioning to meet quality tests. The poly night light has a molded-in clip that allows the display unit to fit into a lamp holder'"'"'s connector for solid installation. The lamp holder can be for an incandescent bulb, neon bulb, LED(s), organic electro-luminescent element(s), or other conventional lighting elements. The poly display unit may have a three-dimensional design, shape, curvature, and/or configuration for an eye-catching, valuable appearance and further may be painted by hand or spray paint to make it more elegant than any other currently-marketed night light.

Claims

1. A polyester night light, comprising:

at least one display unit made of an un-saturated polyester resin (UPR) compound having a three-dimensional configuration;

at least one clip means sealed within the UPR compound material for clipping said display unit onto a lighting fixture;

at least one light means in said lighting fixture for illuminating said display unit; and

at least one holder in said lighting fixture for holding said light means such that light from said light means passes through said display unit made of UPR to enable the light to be seen by viewing a surface of the display unit when said display unit is clipped onto the lighting fixture, said holder including prong means for supplying power to said light means.

2. The polyester night light of claim 1, wherein a material of said clip is selected from the group consisting of plastic, metal, wood, pottery, and porcelain.

3. The polyester night light of claim 1, wherein said light means includes at least one lighting element selected from the group consisting of an incandescent bulb, a neon bulb, an LED, multiple LEDs, and an organic electro-luminescent element.

4. The polyester night light of claim 1, wherein the polyester night light is arranged to pass quality tests including at least one of a drop test, a continuously-on test, an accumulated temperature test, a pulling test, and an oven test.

5. The polyester night light of claim 1, further comprising means for varying a lighting effect provided by said light means, said means for varying a lighting effect selected from the group consisting of an optical fiber, filter, stencil, cut-out, window, overlay, underlay, mask, lens, ink, painting, glue, and combinations said fiber, filter, stencil, cut-out, window, overlay, underlay, mask, lens, ink, painting, and glue.

6. The polyester night light of claim 1, wherein said UPR resin compound is has a predetermined degree of softness sufficient to provide cushioning for elements or said night light.

7. The polyester night light of claim 1, wherein said display unit includes a plurality of windows, cut-outs, or openings through which light beams from said light means are seen by a viewer.

8. The polyester night light of claim 1, wherein said light means includes at least one LED, and said holder includes a sealed unit containing said prong means and all circuitry for driving said LED, said sealed unit being anti-flammable.

9. The polyester night light of claim 1, wherein said clip is molded into said display unit.

10. The polyester night light of claim 1, wherein said display unit is hand-painted in color.

11. The polyester night light of claim 1, wherein said display unit is spray-painted in color.

12. The polyester night light of claim 1, wherein said configuration of said display unit corresponds to a configuration of tooling into which said UPR compound is poured.

13. The polyester night light of claim 1, wherein said UPR compound includes materials added to obtain at least one of a desired softness, clearance, thickness, curing time, and durability.
