Abstract:
An optoelectronic component includes a semiconductor chip that emits a primary radiation in the short-wave blue spectral range at a dominant wavelength of less than approximately 465 nm; and a phosphor that converts at least part of the primary radiation into a longer-wave secondary radiation in the green spectral range at a dominant wavelength of between approximately 490 nm and approximately 550 nm and at least partly surrounds the semiconductor chip, wherein a mixed light composed of primary radiation and secondary radiation has a dominant wavelength at wavelengths of approximately 460 nm to approximately 480 nm such that a luminous flux of the mixed light is up to 130% greater than a luminous flux in an optoelectronic component without a phosphor having the same dominant wavelength in a range of 460 nm to 480 nm, and the phosphor is arranged in a lamina that bears directly on the semiconductor chip.
