    • The electric lamp comprises a lamp vessel (11) which transmits visible light and which accommodates a light source (12). The electric lamp comprises a light-absorbing medium (16). The lamp vessel (11) is covered with an optical interference film (15) which comprises layers composed of a first layer of silica and a second layer of a material having a relatively high refractive index which alternate with each other. According to the invention, light from the light source (12) travels through the light-absorbing medium (16) before reaching the interference film (15). Preferably, the light-absorbing layer (16) is disposed between the lamp vessel (11) and the interference film (15). Alternatively, the light-absorbing layer is contained in a wall of the lamp vessel. Preferably, the interference film (15) reflects substantially in the same wavelength range as that wherein the light-absorbing medium (16) absorbs, preferably in the range from 570 to 620 nm. Preferably, the electric lamp emits, in operation, colored light but has a color-neutral appearance when the lamp is in the off-state. The light-absorbing layer (16) preferably predominantly comprises Nd2O3, CoAl2O4, Fe2O3, ZnFe2O4, ZnO.Fe2O4 or BiVO4.
    • 该电灯包括透过可见光并容纳光源(12)的灯容器(11)。 电灯包括光吸收介质(16)。 灯容器(11)被光学干涉膜(15)覆盖,该光学干涉膜包括由第一层二氧化硅构成的层和具有彼此交替的相对较高折射率的材料的第二层。 根据本发明,来自光源(12)的光在到达干涉膜(15)之前穿过光吸收介质(16)。 优选地,光吸收层(16)设置在灯容器(11)和干涉膜(15)之间。 或者,光吸收层被容纳在灯容器的壁中。 优选地,干涉膜(15)基本上在与吸光介质(16)吸收相同的波长范围内反射,优选在570nm至620nm的范围内。 优选地,电灯在操作中发出彩色光,但是当灯处于关闭状态时具有着色中性的外观。 光吸收层(16)优选主要包含Nd2O3,CoAl2O4,Fe2O3,ZnFe2O4,ZnO.Fe2O4或BiVO4。
