Abstract
A light module includes a first light source. The first light source includes a first light-emitting element and a first lens element. The first light-emitting element includes a first light-emitting chip for emitting a first color light beam and a wavelength conversion material located on the first light-emitting chip for transferring parts of the first color light beam to a second color light beam. The first lens element faces the first light-emitting element and is located on a transmission path of the first color light beam and a transmission path of the second color light beam, and the first lens element includes an optical filter for filtering off the first color light beam and being passed by the second color light beam.
