Abstract: An LED lamp provides a strong red color with a natural appearance. The LED lamp is provided with an LED module and a filter. The LED module includes a blue LED with a main emission peak in the 440 nm to 460 nm wavelength band, a green/yellow phosphor that is excited by light emitted by the blue LED, and a red phosphor that is excited by light emitted by at least one of the blue LED and the green/yellow phosphor. The filter reduces the spectral radiation intensity of at least a portion of the 570 nm to 590 nm wavelength band among light emitted by the LED module.

Abstract: The Ti3+ ions present in Ti-doped silica glass cause a brown staining of the glass, causing inspection of the lens to become more difficult. Known methods for reducing Ti3+ ions in favor of Ti4+ ions in Ti-doped silica glass include a sufficiently high proportion of OH-groups and carrying out an oxygen treatment prior to vitrification, which both have disadvantages. In order to provide a cost-efficient production method for Ti-doped silica glass, which at a hydroxyl group content of less than 120 ppm shows an internal transmittance (sample thickness 10 mm) of at least 70% in the wavelength range of 400 nm to 1000 nm, the TiO2—SiO2 soot body is subjected to a conditioning treatment with a nitrogen oxide prior to vitrification. The blank produced in this way from Ti-doped silica glass has the ratio Ti3+/Ti4+≦5×10−4.
