Claim Text:
1. An array device for converting unpolarized incident light into polarized emitting light, comprising: a polarizing or polarization beam splitter, configured to split the unpolarized incident light into a first polarization wave and a second polarization wave, wherein the polarizing or polarization beam splitter reflects the first polarization wave and allows the second polarization wave passing through thereon; a plurality of converting modules, which receive the second polarization wave and convert a polarization direction of the second polarization wave to a polarization direction of the first polarization wave and guide a converted second polarization wave to an output direction; and a retroreflector, coupled to the polarizing or polarization beam splitter and configured to reflect the first polarization wave to the output direction; wherein, a reflected first polarization wave and the converted second polarization wave are jointed together to form the polarized emitting light.
