  • Light source apparatus and display apparatus
    Patent number: 10838253
    Abstract: A light source apparatus including a light-emitting module and a control unit is provided. The light-emitting module is configured to provide a light. The control unit is configured to make the light switched between a first light and a second light so that at least one of a blue-light hazard and a circadian stimulus value of the light is changed. A wavelength of a blue light main peak in a spectrum of the first light is different from a wavelength of a blue light main peak in a spectrum of the second light.
    Type: Grant
    Filed: October 14, 2019
    Date of Patent: November 17, 2020
    Assignees: Industrial Technology Research Institute, LRU TECHNOLOGY INC.
    Inventors: Tzung-Te Chen, Chia-Fen Hsieh, Tung-Yun Liu, Shih-Yi Wen, Chien-Chun Lu, Hsin-Yun Tsai

  • Light source apparatus and display apparatus
    Patent number: 10485070
    Abstract: An embodiment of the disclosure provides a light source apparatus including a light-emitting module and a control unit. The light-emitting module is configured to provide a light. The control unit is configured to change proportion of a first sub-light and a second sub-light to form the light so that a circadian action factor (CAF) and a correlated color temperature (CCT) of the light varies along a CAF vs. CCT locus of the light different from a CAF vs. CCT locus of sunlight. A CAF vs. CCT coordinate of one of the first sub-light and the second sub-light is below the CAF vs. CCT locus of sunlight, and a CAF vs. CCT coordinate of the other one of the first sub-light and the second sub-light is above the CAF vs. CCT locus of sunlight. A display apparatus is also provided.

  • Light source apparatus
    Patent number: 10039169
    Abstract: A light source apparatus including a light-emitting module and a control unit is provided. The light-emitting module is configured to provide a light. The control unit makes the light emitted from the light-emitting module switched among a plurality of kinds of first light. Correlated color temperatures of the plurality of kinds of first light are different from each other, and circadian action factors of the plurality of kinds of first light are substantially the same as each other.
