1. A light emitting component of a horticultural light, comprising:

  • a light emitting diode (LED) semiconductor chip; and

    a light wavelength up-conversion quantum dot which is deposited in direct proximity of the LED semiconductor chip;

    wherein the light emitting component is configured to emit two characteristic light emission peaks, the light emission at wavelengths of 500-600 nm being reduced below the intensity in the 400-500 nm band and below the intensity in the 600-700 nm band, andthe wavelength up-conversion quantum dot is configured to convert part of the light emission energy emitted by the semiconductor chip to the wavelength of 700 to 800 nm.
