Abstract: PROBLEM TO BE SOLVED: To provide a light source unit realizing a long service life by simply and surely preventing a reflector or a light-transmitting plate from cracking. SOLUTION: In this light source unit U1, an opening in a reflector R is covered with a light-transmitting plate 20 by fixing the light-transmissive plate 20 to an opening peripheral part A of the reflector R, and thus a structure suitable for explosionproof is obtained. During light emission, not only the reflector R but the light-transmissive plate 20 is exposed to a high temperature, and air inside the reflector R maintains at an extremely high temperature. Then, the reflector R and the light-transmitting plate 20 are thermally expanded by the high temperature, and they sometimes crack due to the difference in their coefficients of thermal expansion. To avoid such a situation, a part is cut out of the opening peripheral part A of the reflector R so that a light- transmissive plate housing part 21 is not formed over the entire circumference of the opening peripheral part A of the reflector R. By forming such a cutout in the opening peripheral part A, an escape for stresses due to thermal expansion can be creased, thus surely achieving the crack prevention of the reflector R and of the light-transmissive plate 20.

Abstract: PROBLEM TO BE SOLVED: To provide a light souce unit including a magnet for arc correction capable of being located certainly. SOLUTION: A light source unit 1 is structured so that a magent 22 for correction of arcs is fixed to a reflector R by reference to a terminal mounting part 14 installed on the reflector R for making wiring of a second lead wire 11, so that the magnet mounting works corresponding to the position of the terminal mounting part 14 can be made on the rear surface R1 side of the reflector R. The terminal mounting part 14 is fixed mechanically to the reflector R with the influence of high temp. originating from arc discharge and/or the focal position of reflector R taken into consideration, and generally the arc generating position is set to be at the focal position of the reflector R, so that mounting of the magnet 22 on the reflector R in the described manner ensures location of the magnet 22 with respect to the arc generating position.

Abstract: PURPOSE:To considerably improve the performance of the high-sensitivity dark viewing device by embedding light sources, which successively emit plural infrared rays while turning on/off them, near the periphery of the image pickup center of an object while integrating them to a main body. CONSTITUTION:Plural infrared light emitting diodes 6, 6A and 6B are interally embedded in a main body 1, and the periphery of the image pickup center of an object 5 is successively irradiated with tuning on/off light. The timing of turning on/off the light overlaps the turn-on of the diodes 6 and 6A just for time t, and the light emission of a fluorescent plane 33 is continued without being interrupted. The infrared beams reflected from the object 5 are made incident to an objective lens 2, an image is formed, and the optical image is divided into picture elements by a fiber plate 30 and converted to an electronic image by a photocathode 31. This electronic image is converted to the optical image again on the fluorescent plane 33.
