    • An electric lamp has a light-transmitting lamp vessel (1) with a curved vessel portion (11) accommodating an elongated light source (2). Part of the curved vessel portion (11) is provided with an optical interference film (5) of which the thickness differs locally. The interference film (5) is thicker at locations on the curved vessel portion (11) substantially parallel to the source axis (22) as compared to other locations on the curved vessel portion (11). A method of depositing a layer (5) of a material on a such an electric lamp, includes the steps of : moving the lamp vessel (1) past sources of deposition material while simultaneously rotating the lamp vessel (1) along its vessel axis, locally shielding the lamp vessel (1) to locally reduce the thickness of the deposited material on the lamp vessel (1), the shielding means (55,56) being provided in the vicinity of the lamp vessel (1) and rotating at substantially the same speed as the lamp vessel (1).
    • 电灯具有透光灯容器(1),其具有容纳细长光源(2)的弯曲容器部分(11)。 弯曲容器部分(11)的一部分设置有光学干涉膜(5),其厚度局部不同。 与弯曲容器部分(11)上的其他位置相比,干涉膜(5)在弯曲容器部分(11)上基本上平行于源轴线(22)的位置更厚。 一种在这种电灯上沉积材料层(5)的方法包括以下步骤:使灯泡(1)移动通过沉积材料源,同时沿其容器轴旋转灯泡(1) 局部地屏蔽灯泡(1)以局部减小灯泡(1)上的沉积材料的厚度,屏蔽装置(55,56)设置在灯容器(1)附近并基本上 与灯容器(1)相同的速度。
