| 英文摘要 | A light source device (1) is provided with: a semiconductor light emitting element (11); an optical element (20) which includes a plurality of lens areas (21) and which changes, using the plurality of lens areas (21), the intensity distribution of light emitted from the semiconductor light emitting element (11); and a phosphor element (30) which emits, as excitation light (54), the light with the intensity distribution changed by means of the optical element (20). The plurality of lens areas (21) have respective focal points which are located to the forward or rear of a light emitting surface of the phosphor element (30) and which are different from each other. At least one of the plurality of lens areas (21) is provided with an astigmatism. Excitation light (54a) from the lens area (21a) provided with the astigmatism forms a circle of least confusion (56a) in the vicinity of the focal point, and forms a first focal line (57a) and a second focal line (58a) to the front and rear across the circle of least confusion (56a). Rays of light from the plurality of lens areas (21) overlap each other on a light emitting surface (33) of the phosphor element (30). |
