    摘要： The invention relates to an illumination device (1) comprising an optical waveguide (2) and a number of (connections for) light sources (3)—especially LEDs—positioned along the waveguide (3). This waveguide has a central axis (4) at a distance r to the surface of the waveguide, said surface comprising a light entrance surface (6) on which the (connections for) light sources are positioned and a curved light exit surface (5), wherein, viewed along the circumference of the curved surface (5), the distance r to a first intersection (8) between the flat surface (6) and the curved surface (5), changes to a second distance of different value at the second intersection (9) between said surfaces. The invention also relates to a luminaire comprising such an illumination device (1). Due to the special design of the waveguide (2), the amount of reflections of light in the light sources is largely reduced and desired shaping of the exiting beam can be realized. The device can be further improved by the use of special features, like specially designed curved surfaces (5), reflective structures (13), channels (15) and torus-shaped waveguides.

    摘要： The electric lamp employs a lamp vessel (1), which is transparent to visible light and which accommodates a light source (2). The lamp vessel (1) is covered with a combination of a light-absorbing medium (6) and an optical interference film (5) employing layers of alternately a first layer of a material with a comparatively high refractive index and a second layer of silicon dioxide. A spectral transmission T of light transmitted by the light-absorbing medium (6) changes from T≦0.15 to T≧0.75 in a wavelength range having a width &lgr;≦50 nm. The variation in reflection R amounts to less than 10% in the wavelength range 400≦R≦690 nm, the reflection R and lies in the range 50≦R≦90%. In operation, the electric lamp emits colored light in the transmission mode and has a substantially color-neutral appearance in the off state.

    摘要： 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.
