摘要： A high pressure electric discharge lamp adapted to utilize dielectric barrier discharges can include an arc tube having a discharge space that contains at least a rare gas and an outer tube airtightly surrounding the arc tube. At least one material selected from Ne, Ar, Kr, Xe, F2, Cl2, Br2, I2 and N2 or a mixture thereof that are apt to produce a dielectric barrier discharge can be filled in the space between the arc tube and the outer tube at pressure preferably between 1.3 and 100 [kPa] and more preferably between 40 and 80 [kPa]. The type and the pressure of the rare gas contained in the space is selected as to make the dielectric barrier discharge starting voltage in the space lower than the discharge starting voltage in the discharge space.

摘要： Light source devices for photography using LED elements as a light source known in the prior art provide insufficient quantity of light, and the inability to avoid size increases in order to generate a sufficient quantity of light has been problematic. A photography light source device 1 according to the present invention has a light source comprising a plurality of LED elements 2 generating white light or light of the three primaries and arranged in one or more rows parallel with the direction of the longer side of the photograph, a case 3 having a lens on which linear fresnel cuts 3a have been applied in a linear direction parallel to the arrangement direction is mounted on the LED element 2, and upon lighting of the LED element 2, drive is performed with a current of between 3 and 50 times the magnitude of the rated current thereof and a lighting duration of between 10 and 600 msec. Accordingly, the linear fresnel cuts 3a increase the efficiency of illumination by distributing light uniformly over the area of exposure, and in addition, a large current is applied in a pulse type pattern as the drive current, thus solving the problems by allowing sufficient brightness to be achieved with no associated increases in size.
摘要翻译：使用LED元件作为现有技术中已知的光源的摄影用光源装置提供不足量的光，并且为了产生足够量的光而不能避免尺寸增加的问题。根据本发明的摄影光源装置1具有光源，该光源包括产生白光或三原色光的多个LED元件2，并且被布置成与照片的长边方向平行的一行或多行，在LED元件2上安装具有沿平行于排列方向的线性方向施加线性菲涅尔切口3a的透镜的壳体3，并且在LED元件2点亮时，以其间的电流进行驱动其额定电流的大小为3和50倍，照明持续时间为10至600毫秒。因此，线性菲涅尔切口3通过在曝光区域均匀分布光而提高照明效率，此外，以脉冲型图案作为驱动电流施加大电流，从而通过允许足够的亮度来解决问题要实现，没有相关的规模增加。
