    • A light emitting sign comprising a light emitting display surface including at least one phosphor, and at least one radiation source configured to irradiate the display surface with excitation energy such that the phosphor emits light of a selected color. The sign further comprises a filter which is substantially transparent to light emitted by the display surface, filtering other colors of light. The display surface may be configured into a shape of a character, a symbol, or a device.
