Abstract

A magnetic light panel. The magnetic light panel includes an acrylic substrate, a reflective substrate adjacent an internal surface of the acrylic substrate, a light directed toward a continuous edge of the acrylic substrate, a ferromagnetic substrate adjacent to the reflective substrate, and a housing.

Claims (36)

1 . A magnetic light panel, comprising:

an acrylic substrate viewing screen having:

an exposed surface;

an internal surface;

a continuous edge;

a thickness of 2.5 millimeters or less; and

a series of light transmitting marks formed on the internal surface of the acrylic substrate;

a light reflecting reflective substrate adjacent the internal surface of the acrylic substrate;

a light directed toward the continuous edge of the acrylic substrate;

a ferromagnetic substrate adjacent to the reflective substrate; and

a housing adjacent the ferromagnetic substrate, the housing having a continuous lip extending from an outer edge of the housing, the continuous lip retaining the acrylic substrate, the reflective substrate, the light source, and the ferromagnetic substrate in place.

2 . The magnetic light panel of claim 1 , wherein the ferromagnetic substrate is a steel sheet having a thickness of at least 0.5 mm.

3 . The magnetic light panel of claim 1 , wherein the reflective substrate is a reflective paper.

4 . The magnetic light panel of claim 1 , wherein the light is a light emitting diode strip that extends along at least one of four sides of the acrylic substrate continuous edge.

5 . The magnetic light panel of claim 4 , wherein light emitted from the light-emitting diode strip reflects off the light transmitting marks for viewing on the exposed surface of the acrylic substrate.

6 . The magnetic light panel of claim 5 , wherein light emitted from the light-emitting diode strip reflects from the light transmitting marks off the reflective substrate for viewing on the exposed surface of the acrylic substrate.

7 . The magnetic light panel of claim 4 , wherein the light is a light emitting diode strip that extends around a circumference of the acrylic substrate continuous edge.

8 . The magnetic light panel of claim 1 , further comprising a removable magnet adjacent the exposed surface of the acrylic substrate and having a magnetic field that attracts the magnet to the ferromagnetic substrate, the magnet to be placed on and removed from the acrylic substrate by a human.

9 . The magnetic light panel of claim 8 , wherein the magnet is a ferrite magnet.

10 . The magnetic light panel of claim 8 , wherein the panel has a magnetic attraction such that a magnet of not more than 113 cubic millimeters, will remain on the exterior surface when a pull force equal to 0.6 newtons is applied to the magnet perpendicular to the acrylic substrate.

11 . The magnetic light panel of claim 1 , wherein the acrylic substrate has a thickness of not more than 2 mm.

12 . The magnetic light panel of claim 1 , wherein the acrylic substrate has a thickness of not more than 1.5 mm.

13 . The magnetic light panel of claim 1 , wherein the housing is wood.

14 . A method of creating a magnetic light panel, comprising:

providing a ferromagnetic substrate under an acrylic viewing screen having a thickness of 2.5 millimeters or less;

directing LED light into an edge of the acrylic viewing screen onto a series of reflective marks for viewing on an exposed surface of the acrylic viewing screen;

a housing adjacent the ferromagnetic substrate, the housing having a continuous lip extending from an outer edge of the housing, the continuous lip retaining the acrylic viewing screen, the light source, and the ferromagnetic substrate in place; and

magnetically affixing a magnet to the acrylic viewing screen.

15 . The method of creating a magnetic light panel of claim 14 , wherein the reflective marks reflect the LED light onto the acrylic viewing screen.

16 . The method of creating a magnetic light panel of claim 14 , further comprising placing a reflective material adjacent an internal surface of the acrylic viewing screen to reflect the LED light onto the acrylic viewing screen.

17 . The method of creating a magnetic light panel of claim 15 , wherein the acrylic viewing screen has a thickness of less than 2 millimeters.

18 . A method of using a portable magnetic light panel, comprising:

placing a magnet on a viewing surface of an acrylic viewing screen having a plurality of reflective marks that transmit light to a viewing surface of the viewing screen, the magnet having a cubic dimension of not more than 113 cubic millimeters and having a magnetic attraction such that the magnet will remain adjacent to the acrylic viewing screen when a pull force of 0.6 newtons is applied to the magnet perpendicular to the acrylic viewing screen, a magnetic substrate retained adjacent an internal surface of the acrylic viewing screen opposite the viewing surface of the acrylic viewing screen by a housing, the magnetic substrate attracting the magnet; and

directing LED light into a side of the acrylic viewing screen onto the plurality of reflective marks such that light from the LED light is reflected off the reflective marks for viewing on the exposed surface of the acrylic viewing screen.

19 . The method of using a magnetic light panel of claim 18 , further comprising reflecting light from the LED off a reflective substrate adjacent an internal surface of the acrylic substrate.

20 . The magnetic light panel of claim 19 , further comprising placing a diffuser sheet on the exterior surface of the acrylic sheet to be present between the acrylic sheet and the magnet.
