  • Patent number: 11500135
    Abstract: Incident optical signals propagate within a diffuser substrate and impinge upon an optical diffuser within the diffuser substrate or on its output surface. The optical diffuser redirects or transforms respective portions of each incident signal into corresponding forward- and backward-directed optical signals. The backward-directed signals are redirected or transformed into additional incident signals, and so on. The forward-directed optical signals collectively form the optical output of an illumination source that exhibits reduced speckle. The illumination source can include multiple laser sources formed on or attached to an input surface of the diffuser substrate.

  • Patent number: 11473748
    Abstract: A rotation light source lamp system is combined with a rotation light source device in which a chromatic aberration correction unit obviates focal distance differences occurring between incident paths “a” of lights emitted by LED light sources sequentially synchronized and turned on when first to N-th LED chips arrive at a location where each LED chip faces a signal transmitter while the first to N-th LED chips are rotated once in response to the application of a lamp turn-on signal for the vehicle from the signal transmitter. Chromatic aberration can be reduced by correcting a difference between refractive indices for each wavelength having a different color in the first to N-th LED chips.
