Abstract

The present invention provides a light emitting apparatus and a lighting module, comprising: a circuit substrate, a plurality of optical sources and an optical element; the optical element comprises a translucent element and an interference element; the plurality of light sources are arranged on the circuit substrate for lighting the optical element; the optical element is arranged above the plurality of light sources; and the interference element is arranged on the translucent element, which is used to make light emitted from each of the light sources offset interference in a first polarization direction, enhance interference in a second polarization direction, and emit through the translucent element. The light emitting apparatus and the lighting module of the present invention are employed to provide a more diversified optical pattern to the user and improve the user experience.
