摘要:
An electroluminescent device includes a substrate and a laminated body composed of a first electrode, an electroluminescent layer and a second electrode. The light output out of the electroluminescent device is increased by arranging a colloidal layer between the substrate and the laminated body. By using pigments in the colloidal layer, the emission color of the electroluminescent device can be changed and the daylight contrast improved.

The invention relates to an electroluminescent device comprising a substrate (1) and a laminated body composed of a first electrode (3), an electroluminescent layer (4) and a second electrode (5). The light output out of the electroluminescent device is increased by arranging a colloidal layer (2) between the substrate (1) and the laminated body. By using pigments in the colloidal layer (2), the emmission color of the electroluminescent device can be changed and the daylight contrast improved.

A plasma picture screen is disclosed. In one embodiment, an AC plasma picture screen with a coplanar arrangement which has an enhanced luminance is provided. A layer, which has a high reflection in the wavelength range of the plasma emission (145 to 200 nm) and a high transmission in the visible wavelength range, is provided on the front plate. The front plate includes a glass plate on which a dielectric layer, a protective layer, a reflective layer are provided. The reflective layer reflects UV light emitted in the direction of the front plate back towards phosphors. The optical properties of the UV light reflecting layer are realized with inorganic particles with a particle diameter of between 200 nm and 500 nm and a layer thickness from 0.5 &mgr;m to 5 &mgr;m, or with agglomerates of inorganic particles with a particle diameter of between 10 nm and 200 nm and a layer thickness of 0.2 &mgr;m to 10 &mgr;m.

A colored luminaire, in particular a colored signaling light for automobiles, fitted with a lamp and a luminaire cover in which the lamp has a bulb with a coating of a first layer comprising a pigment, which pigment is chosen from the group of perylene pigments, perinone pigments, isoindoline pigments, and thioindigo pigments, is remarkable for a long useful life. It is not attacked by UV radiation, moisture, and spraying salt and is resistant to temperatures of between 250 and 350° C. Colored luminaires with bulb coatings comprising these pigments alone or in combination with further pigments for color correction comply with the color standards for automobile luminaires.

The invention relates to a printing form for a rotary relief-printing method, in which the printing dots transferring the printing ink constitute a half-tone screen and are superimposed by a relief structure constituted by indentations. Such printing forms are used, for example in flexographic printing methods for printing glass plates, for example display screens having a luminescent material coating. In the manufacture of these screens, the printing ink must be applied homogeneously and the ink dots appearing in the printed image must have a uniform border area. According to the invention, the printing form is to this end implemented in such a way that the relief structures are arranged homogeneously relative to the printing dots and, if the printing dots are periodically spread across the printing form, these relief structures are superimposed on the printing dots preferably with the same period. Moreover, the relief structures are arranged in such a way that the indentations do not intersect the border area of a printing dot.

The invention relates to GLS-look-alike LED light source (100) comprising two different types of LEDs (21, 22), preferably LEDs emitting with a near UV spectrum and a blue or white spectrum, respectively. The light source (100) further preferably comprises a transparent bulb (40) with a shape similar to an incandescent lamp that is coated by a luminescent layer (30) to achieve a white lamp spectrum. The luminescent layer may contain one or two luminescent compositions.
