On the basis of light emitting diodes - chips operating with only two different colors white light source emitting light emitting diodes - chips

摘要

The white light source with a the additives which enhance color mixing arrangement of light in different colors emitting light emitting diodes - chips, characterized by an arrangement of two in the colors blue in the case of a peak wavelength of 425 to 460 nm, as well as a yellowish green in the case of a peak wavelength of 560 to 570 nm light emitting light emitting diodes - chips (11, 12), wherein the light density (cd / m²) and / or the luminosities (cd) of the blue light emitting light emitting diodes - chips (11) and of the yellowish green light emitting light emitting diodes - chips (12) in a ratio between 1: 5 and 1: 8 are adjusted.
