Abstract
An holder or support for a backlit component is disclosed which provides display lighting for the backlit component. The holder may be a one-piece holder and may be made from a polymeric material including one or more fluorescing materials and/or diffusing substances. A trim plate for a backlit display is disclosed. The trim plate may have a front face which provides both a solid support for graphic indicia and display lighting for the graphic indicia.
Claims6
An apparatus for providing a backlit display, the apparatus comprising:
- at least one illumination source configured to emit a cone of light having a first spectrum;
- a backlit component;
- and
- a one-piece holder configured to support the backlit component, the holder having a first portion positioned between the at least one illumination source and the backlit component, the first portion including a fluorescing material which absorbs at least a portion of light having the first spectrum and emits light having a second spectrum to provide appropriate lighting for the backlit component, where said first portion has a shape that approximates a wavefront of said cone of light so that all light rays within said cone of light have a substantially equal path length through said first portion and substantially equal absorption by said fluorescing material.
A method for providing a backlit display, the method comprising the steps of:
- providing a backlit component and at least one illumination source configured to emit a cone of light having a first spectrum;
- and
- positioning a holder between the illumination source and the backlit component, the holder having a light-transmitting first portion including one or more fluorescing materials which absorb light of the first spectrum and emit light of a second spectrum for backlighting the backlit display, said first portion having a shape that approximates a wavefront of said cone of light so that all light rays within said cone of light have a substantially equal path length through said first portion and substantially equal absorption by said fluorescing materials.
