Light source device for light emission body by optical fiber

Abstract

Abstract PURPOSE:To obtain the light source device which has high light source utilization efficiency and is easily manufactured and adjusted by entering and converging luminous flux which is converged by a reflecting mirror or lens system from the large-diameter side to the small-diameter side of a conic tube body whose internal wall is machined into a reflecting mirror surface. CONSTITUTION:The conic tube body 5 is fitted to a hemispherical reflecting mirror case 2. Then a light source 1 is arranged nearby the focus of the hemispherical reflecting mirror 2a. The reflecting mirror 2a in the hemispherical reflecting mirror case 2 converges light, and then a light beam which becomes almost parallel or convergent and other necessary emitted light are all guided and converged to the small-diameter side of the conic tube body 5. The majority of the light emitted by the light source 1 is made incident on the end surface of an optical fiber bundle part 7 on the small-diameter side. Consequently, the utilization efficiency of the light source is good and the adjustment and manufacture of the device are easy.
