摘要： The invention aims to provide small-sized and highly-reliable light converter and light source unit, as well as a projector each of which makes it possible to cool down heat generated in a fluorescent body in a motorless manner. A light converter of the disclosure includes: a fluorescent body (12) that is excited by excitation light; a first light-collecting lens (11A) that has a lens surface to which the fluorescent body is bonded, and causes the excitation light to enter the fluorescent body; and a heat-dissipating member (14) to which the lens surface is adhered at least around a region to which the fluorescent body is bonded.

摘要： A light source apparatus (1) according to the present disclosure includes a wavelength conversion device (10) that includes two or more wavelength conversion units (11-13) serially coupled in a first direction. The wavelength conversion device (10) has a configuration in which the two or more wavelength conversion units (11-13) generate respective converted lights having wavelengths different from each other to generate two or more converted lights. The two or more wavelength conversion units (11-13) each include a first end surface and a second end surface that are formed in a direction parallel to the first direction, and a light entering surface (43) that is formed in a second direction different from the first direction and which an excitation light for generating the converted light enters. The first end surface (41) of one wavelength conversion unit (13) positioned at one end of the wavelength conversion device (10) of the two or more wavelength conversion units (11-13) is configured to be a light extraction surface from which the two or more converted lights are extracted out of the excitation light and the two or more converted lights.

摘要： An illumination unit of the present disclosure includes an excitation light source, a phosphor section, an excitation-light intensity distribution generation section, and an illumination optical system. The excitation light source emits excitation light. The phosphor section includes a fluorescent light-emission surface that performs fluorescent light emission in response to receiving of the excitation light. The excitation-light intensity distribution generation section is provided between the excitation light source and the phosphor section, and varies an intensity distribution of the excitation light to bring the intensity distribution of the excitation light closer to a desired excitation-light intensity distribution on the fluorescent light-emission surface. The illumination optical system generates, on the basis of light derived from the fluorescent light emission from the phosphor section, illumination light with which an image display device is to be irradiated.
