Illuminator having forward lighting
View Patent ↗A box-like illuminator includes a top wall having a flat sheet of clear material through which an illuminated image is viewed. A bottom wall of the illuminator is also formed of a flat sheet of clear material and is positioned atop the object to be illuminated. Light from an LED is directed in a first, downward direction onto a deflection wall where it is deflected into a substantially horizontal plane, substantially orthogonal to the first direction. The deflected light impinges upon a horizontally-disposed diffuser that bends the light about ninety degrees so that it travels though the diffuser a first time in a first direction and illuminates the object atop which the illuminator is positioned. The light is then reflected by the object, travels upwardly through the diffuser a second time in a direction opposite to the first direction, and is viewed by the user through the clear material.
1. An illuminator, comprising:
a top wall having an opening formed therein;
a flat sheet of clear material mounted in said opening formed in said top wall;
a bottom wall formed of a flat sheet of clear material;
a plurality of sidewalls disposed in interconnecting relation to said top wall and said bottom wall at the respective peripheries of said top wall and said bottom wall;
said bottom wall being adapted to sit atop an object to be illuminated and to be slideably moved with respect to said object with a low friction interface between said bottom wall and said object;
a light source adapted to emit light;
a light guide that guides light emitted by said light source;
a diffuser mounted in parallel relation to said object;
said diffuser mounted a fixed distance from said object;
said light guide adapted to guide light from said light source into a horizontal path of travel where said light travels substantially parallel to a rough top surface of said diffuser until said light is bent by and passes through said diffuser in a first downward direction so that said light is adapted to impinge upon said object;
whereby said light passes through said diffuser a second time in an upward direction opposite to said first downward direction after reflecting from said object; and
whereby said object is viewed by a user through said flat sheet of clear material formed in said top wall.
2. The illuminator of claim 1 , further comprising:
said light source being a source of white light.
3. The illuminator of claim 1 , further comprising:
said light source being at least one light-emitting diode.
4. The illuminator of claim 1 , further comprising:
said light guide being formed of a transparent material.
5. The illuminator of claim 1 , further comprising:
said flat sheer of clear material formed in said top wall and said flat sheet of material forming said bottom wall being a material selected from a group of clear material consisting of glass, plastic, acrylic, and polycarbonate.
