Led lamp for growth of plant

PURPOSE: An LED lamp for growing a plant is provided to adaptively emit light to various plants by controlling a photon flux ratio through the control of currents supplied to a white LED and a red LED. CONSTITUTION: An LED lamp has red LEDs and white LEDs with a ratio of 2:1. The white LED includes light of a violet wavelength, an indigo wavelength, a blue wavelength, a green wavelength, a yellow wavelength, an orange wavelength, and a red wavelength. A photon flux ratio of the red wavelength is 18.9 to 49.1 %. A photon flux ratio of the violet wavelength is 13.3 to 21.2 %. A photon flux ratio of the indigo wavelength is 3.3 to 5.3 %. A photon flux ratio of the blue wavelength is 3.4 to 5.5 %. A photon flux ratio of the green wavelength is 16.8 to 26.7 %. A photon flux ratio of the yellow wavelength is 8.6 to 13.7 %. A photon flux radio of the orange wavelength is 5.4 to 8.7 %. The photon flux ratio is controlled by controlling the intensity of currents supplied to the red LED and the white LED.
