    摘要: The invention describes a lamp (1A, 1B, 1C, 1D) comprising a glass envelope (10) enclosing a light generating means (11), and an axially and/or circumferentially graded absorption coating (2A, 2B, 2C, 2D) applied to a surface of the glass envelope (10), wherein the graded absorption coating (2A, 2B, 2C, 2D) exhibits a smooth transition in a transition region (23A, 23B, 23C, 23D) from a first coated region (21 A, 2 1B, 21C, 2 1D) on the glass envelope (10) to a second coated region (22A, 22B, 22C, 22D) on the glass envelope (10). The invention further describes a lighting assembly (4) comprising a lamp according to any of claims 1 to 11 and a reflector (40) for collecting and shaping any light passing through the graded absorption coating (2A, 2B, 2C, 2D) of the lamp (1A, 1B, 1C, 1D). The invention also describes a method of manufacturing a lamp (1A, 1B, 1C, 1D) comprising a glass envelope (10) enclosing a light generating means (11), which method comprises applying an axially and/or circumferentially graded absorption coating (2A, 2B, 2C, 2D) to a surface of the glass envelope (10) such that the graded absorption coating (2A, 2B, 2C, 2D) exhibits a smooth transition in a transition region (23A, 23B, 23C, 23D) from a first coated region (21A, 21B, 21C, 21D) to a second coated region (22A, 22B, 22C, 22D).

    摘要翻译: 本发明描述了一种灯(1A,1B,1C,1D),其包括封闭发光装置(11)的玻璃外壳(10),以及施加有轴向和/或周向渐变的吸收涂层(2A,2B,2C,2D) 其中所述渐变吸收涂层(2A,2B,2C,2D)在过渡区域(23A,23C,23D)中从第一涂覆区域(21A,21B)转移到所述玻璃外壳(10)的表面, ,21C,21D)放置在玻璃封套(10)上的第二涂覆区域(22A,22B,22C,22D)上。 本发明还描述了一种包括根据权利要求1至11中任一项所述的灯的照明组件(4)和用于收集和成形通过所述渐变吸收涂层(2A,2B,2C,2D)的任何光的反射器(40) 灯(1A,1B,1C,1D)。 本发明还描述了一种制造包括封闭发光装置(11)的玻璃外壳(10)的灯(1A,1B,1C,1D)的方法,该方法包括将轴向和/或周向渐变吸收涂层(2A ,2B,2C,2D)到玻璃外壳(10)的表面,使得渐变吸收涂层(2A,2B,2C,2D)在过渡区域(23A,23B,23C,23D)中呈现平滑过渡 第一涂覆区域(21A,21B,21C,21D)到第二涂覆区域(22A,22B,22C,22D)。
