    • The invention relates to a high-pressure discharge lamp of the ceramic metal halide type of the Philips MasterColor series having a molybdenum coil wrapped around the discharge vessel and at least a portion of the electrode feed through means, and having power ranges of about 150 W to about 1000 W. Such lamps are provided with a discharge vessel which encloses a discharge space. The discharge vessel has a ceramic wall and is closed by a ceramic plug. An electrode which is located inside the discharge space is connected to an electric conductor by way of a leadthrough element. The leadthrough element projects through the ceramic plug with a close fit and is connected thereto in a gastight manner by way of a sealing ceramic. The leadthrough element has a first part which is formed by a cermet at the area of the gastight connection. In addition, the lamps display one or more and most preferably all of the following properties: a CCT (correlated color temperature) of about 3800 to about 4500K, a CRI (color rendering index) of about 70 to about 95, a MPCD (mean perceptible color difference) of about ±10, and a luminous efficacy up to about 85-95 lumens/watt, a lumen maintenance of >80%, color temperature shift
    • 本发明涉及飞利浦MasterColor系列的陶瓷金属卤化物型高压放电灯,其具有缠绕放电容器的钼线圈和电极馈送装置的至少一部分,功率范围约为150W 至约1000W。这样的灯具有封闭放电空间的放电容器。 放电容器具有陶瓷壁并由陶瓷塞封闭。 位于放电空间内的电极通过穿通元件与电导体连接。 引导元件通过紧密配合的陶瓷塞突出,并通过密封陶瓷以气密方式连接到陶瓷塞。 引导元件具有由金属陶瓷在气密连接区域形成的第一部分。 此外,灯显示一个或多个,最优选全部以下性质:约3800至约4500K的CCT(相关色温),约70至约95的CRI(显色指数),MPCD(平均值 可感知的色差)为约±10,发光效率高达约85-95流明/瓦,流明维持率> 80%,色温偏差为200K至100,000至8000,寿命约10,000小时至约25,000 小时。 本发明还涉及用于设计和构造大功率灯的设计空间以及使用设计空间来构造这种灯的方法。
