  • Light source unit
    Patent number: 9678418
    Abstract: A light source unit includes a light source which emits a light bundle in one direction; a polarizing unit which is formed to selectively transmit a certain polarized light of a certain wavelength in the light bundle; and a reflection unit which is formed so as to delay the phase of the polarized light so that the polarized light is reflected by the polarizing unit, convert one part of the wavelength of the polarized light, and reflect the polarized light toward the polarizing unit.
    Type: Grant
    Filed: September 24, 2013
    Date of Patent: June 13, 2017
    Assignee: LG ELECTRONICS INC.
    Inventors: Byungwoo Jeoung, Yongwoo Bae, Kihyuk Song, Sangok Yeo
  • Light source assembly and projector having the same
    Patent number: 9360745
    Abstract: A light source assembly includes a plurality of first light sources disposed on a first plane to emit light, a plurality of second light sources disposed on a second plane, the second plane spaced apart from the first plane with a preset interval, wherein each second light source emits light between the adjacent first light sources, and a lens configured to concentrate light emitted from the plurality of first and second light sources. A projector having the light source assembly is also provided.
