Phosphors for conversion of the ultraviolet or blue emission of a light-emitting element in visible white radiation having a very high color rendering

2002 
The invention relates to phosphors for conversion of the ultraviolet or blue emission of a light-emitting element in visible white radiation having a very high color rendering and an Ra of up to about the 99th The phosphors consist of an emitting component, formed of solid systems Erdalkaliantimonate and derived systems such as the Fluoroantimonaten having a red self-luminescence, or manganese (IV) -activated oxygen dominated phosphor systems or of europium - activated silicate - germanates or systems in which a sensitizer from the series of Eu (II) and as a secondary activator Mn (II) is used, with the color orange or orange-red or red, or deep red in the spectral range above 600 nm, or from a mixture of up to 8 phosphor components having different emission bands, their superposition a wide emission continuum between about 380 nm and 780 nm with color temperatures between about 10,000 K with a color Blue White and 6500 K with the color of daylight and a color temperature of about 3,000 K with color warm white to a color temperature of 2000 K, with the color of reddish-yellow Abendlicht generated. Field of the invention, the semiconductor opto-electronic technology and the lighting equipment. The location of this white light emitting elements with the novel phosphors especially where it comes to a faithful color reproduction.
