  • Patent number: 10031407
    Abstract: A light source unit including: a plurality of elemental light sources each including a light emitting element and a drive circuit; a control circuit configured to control the drive circuit; and a luminous flux characteristic measurement section configured to measure received output luminous fluxes to generate luminous flux chromaticity-intensity correlation data. The control circuit generates a single-color color-phase indicating value, based on the luminous flux chromaticity-intensity correlation data. The control circuit determines a ratio of intensity of additional light to intensity of main component light to allow the single-color color-phase indicating value to become equal to a target value thereof, and generates an integrated color-phase indicating value, based on the luminous flux chromaticity-intensity correlation data. The control circuit performs feedback control on the drive circuits to allow a difference between the integrated color-phase indicating value and a target value thereof to be small.

  • Patent number: 9939718
    Abstract: A light source apparatus includes a polarization conversion element, a fluorescent substance and a light source element. The polarization conversion element has a p/s-polarizing beam splitter film to separate polarization components of incident light into p-polarization component and s-polarization component. The fluorescent substance emits visible light as the incident light that is incident on the p/s-polarizing beam splitter film, which visible light is generated by that the fluorescent substance is excited by excitation light, and has a wavelength of longer wavelength region than a wavelength of the excitation light. The light source element emits a laser beam having a predetermined wavelength as the excitation light to irradiate the fluorescent substance with the excitation light so that a laser beam having a polarization plane between the polarization plane of p-polarized light and the polarization plane of s-polarized light exiting from the fluorescent substance is emitted as the incident light.
