    摘要： An arrangement for emitting mixed light including a primary and secondary radiation with at least one first electroluminescent light-source for emitting first primary radiation, at least one second electroluminescent light-source for emitting second primary radiation, and a light-converting element for absorbing at least one of the primary radiations and re-emitting the secondary radiation. The light-converting element is arranged so that the entire proportion of primary radiation in the mixed light passes through the light-converting element. The light-converting element is a ceramic light-converting material whose microstructure is selected to be such that the color point of the mixed light of primary and second radiation is substantially independent of the angle of viewing.

    摘要： The invention relates to an illumination device (10) that comprises an active layer (11), for example a blue LED, covered with a first luminescent ceramic converter layer (12) and partially covered with a second luminescent ceramic converter layer (13). The first and second conversion layers (12, 13) convert primary photons (λp) emitted by the active layer (11) into photons of different, longer wavelengths (λ1, λ2), wherein the color point of the illumination device (10) can be adjusted by adjusting the relative size of the second conversion layer (13).

    摘要： A low-pressure mercury vapor discharge lamp has a light-transmitting discharge vessel (10) enclosing, in a gastight manner, a discharge space (13) provided with a filling of mercury and a rare gas. The discharge vessel comprises discharge means for maintaining a discharge in the discharge space. The discharge vessel is provided with a luminescent layer (17) comprising a mixture of at least a red and a green luminescent material. The red luminescent material comprises (Y,Gd)2O3:Eu. The green luminescent material comprises (Ba,Ca,Sr)2SiO4:Eu and/or (Sr,Ca,Ba,Mg,Zn)Si2N2O2:Eu. Particles of the green luminescent material are surrounded by a coating of aluminum oxide. Preferably, at least 50% of the particles of the green and red luminescent materials have an average diameter greater than or equal to approximately 5 μm. The mixture of the red and green luminescent materials render a low-pressure mercury-vapor discharge lamp with an improved lumen equivalent.
