    • The invention relates to an illumination system(100), a high-pressure discharge lamp (90) and an image projection system. The illumination system comprises a high-pressure discharge lamp and aback reflector (30) reflecting the light emitted by the high-pressure discharge lamp towards a light exit window (50). The back reflector comprises an optical axis (55). The high-pressure discharge lamp comprises a discharge vessel (90) comprising two electrodes (98, 99) between which, during operation, a discharge arc is produced. The discharge vessel comprises a first part (10) arranged at least partially between the discharge arc and the back reflector, and a second part (20) arranged at least partially between the discharge arc and the light exit window. The second part has a different shape compared to the first part, thereby forming a refractive element in the second part for reducing an angular distribution at the light exit window of the light emitted from the discharge arc and refracted By the second part. The measures according to the invention have the effect that,due to the reduction of the angular distribution at the light exit window,the specific refractive property of the second part improves the efficiency of the illumination system.
    • 本发明涉及照明系统(100),高压放电灯(90)和图像投影系统。 照明系统包括高压放电灯和将由高压放电灯发射的光朝向光出射窗(50)反射的反射器(30)。 后反射器包括光轴(55)。 高压放电灯包括一个包括两个电极(98,99)的放电容器(90),在其间在工作期间产生放电电弧。 放电容器包括至少部分地布置在放电弧和后反射器之间的第一部分(10)和至少部分地布置在放电弧和光出射窗之间的第二部分(20)。 第二部分与第一部分相比具有不同的形状,从而在第二部分中形成折射元件,用于减小从放电弧发射的光的光出射窗处的角分布,并由第二部分折射。 根据本发明的措施具有这样的效果:由于在光出射窗处的角度分布的减小,第二部分的比折射特性提高了照明系统的效率。
