摘要:
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.
