Each display element comprises: a light guiding medium having a light emitting display face; at least one excitation source (LED) associated with the light guiding medium and independently operable to generate excitation light of a first wavelength range and couple the excitation light into the light guiding medium; and a pattern of at least one phosphor material provided on the light emitting surface and configured to define the light emitting element wherein the phosphor material absorbs at least a part of the excitation light and emits light of a second wavelength range. Each display element can comprise a discrete light guiding medium or display elements can be defined within a single light guiding medium by one or more light reflecting planes.

    Abstract: A color/color temperature tunable light emitting device comprises: an excitation source (LED) operable to generate light of a first wavelength range and a wavelength converting component comprising a phosphor material which is operable to convert at least a part of the light into light of a second wavelength range. Light emitted by the device comprises the combined light of the first and second wavelength ranges. The wavelength converting component has a wavelength converting property (phosphor material concentration per unit area) that varies spatially. The color of light generated by the source is tunable by relative movement of the wavelength converting component and excitation source such that the light of the first wavelength range is incident on a different part of the wavelength converting component and the generated light comprises different relative proportions of light of the first and second wavelength ranges.
