摘要： A light source device includes: a rotating body configured to be rotated with a rotating shaft as a center; a first wavelength conversion portion arranged on a circumference of a circle of a predetermined radius with the rotating shaft as the center in the rotating body, and configured to be irradiated with light to generate light of a wavelength different from a wavelength of the light; and a second wavelength conversion portion arranged on a circumference of a circle of a radius larger than the predetermined radius with the rotating shaft as the center in the rotating body, configured to be irradiated with light to generate light of a wavelength different from a wavelength of the light, and including a characteristic that conversion efficiency of the wavelength declines due to rise of a temperature more than the first wavelength conversion portion.

摘要： A light source device includes light sources, a light output unit, optical filters, temperature sensors detecting current temperatures of the sources, light quantity sensors detecting current light quantities of light beams before traveling through the filters, a storage, and a processor. The storage stores first correlation information between the temperatures of the sources and spectral information and second correlation information between the spectral information and light quantity of light at the unit. The processor is configured to calculate a variation in the spectral information based on each current temperature and the first information, calculate a variation in the light quantity of the light at the unit caused by a change in the spectral information based on the variation in the spectral information and the second information, and calculate a light-quantity correction amount for each of the sources based on the variation in the light quantity and the current light quantity.

摘要： A light source device includes a semiconductor light-emitting device which emits coherent excitation light, and a wavelength conversion element which is spaced from the semiconductor light-emitting device, generates fluorescence by converting the wavelength of the excitation light emitted from semiconductor light-emitting device, and generates scattered light by scattering the excitation light. The wavelength conversion element includes a support member, and a wavelength converter disposed on the support member. The wavelength converter includes a first wavelength converter, and a second wavelength converter which is disposed around the first wavelength converter to surround the first wavelength converter in a top view of the surface of the support member on which the wavelength converter is disposed. The ratio of the intensity of fluorescence to that of scattered light is lower in the second wavelength converter than in the first wavelength converter.

摘要： An optoelectronic device includes a number of pixels, with each pixel including a lighting mechanism having at least one light-emitting diode capable of emitting an initial light beam, a light-conversion module having a plurality of conversion pads including at least one primary conversion pad and at least one secondary conversion pad. Each pixel includes a light-adjustment system configured to control at least one element chosen from a relative position between the lighting mechanism and the light-conversion module and the initial light beam. The action of the light-adjustment system is adapted so that the primary conversion pad and the secondary conversion pad emit a first light beam and a second light beam respectively, from the initial light beam, simultaneously or alternately in a predetermined sequence.
