Abstract
A white-light emitting semiconductor device includes a first light-emitting die, a second light-emitting die, a photostimulable luminescent substance, and a holding assembly. The first light-emitting die emits a first radiation having a first wavelength range. The second light-emitting die emits a second radiation having a second wavelength range, and a third radiation having a third wavelength range different from the second wavelength range. The photostimulable luminescent substance is excitable to emit a fourth radiation having a fourth wavelength range. The fourth radiation is mixed with the first, second, and third radiations to result in white light. The holding assembly holds the first and second light-emitting dies, and the photostimulable luminescent substance.
