Abstract

The invention discloses an LED light source capable of promoting fruit fullness. The LED light source is obtained by jointly packing a near ultraviolet chip and fluorescent powder coated on the surface of the near ultraviolet chip, the fluorescent powder includes red fluorescent powder, blue fluorescent powder, near ultraviolet fluorescent powder and green fluorescent powder according to a mass ratio of (1-4):(0.5-1):(0.1-0.5), and mass of the green fluorescent powder is 0.25-0.5 time that of the red fluorescent powder. The LED light source which is a plant growth light source is high in excitation efficiency and light efficiency, wide in light spectrum and conducive to plant absorption, and absorbing effectiveness to the light spectrum can be adjusted according to light elements needed by plants in the fruiting period to meet special needs of the plants on light in the fruiting period.

Description

technical field [0001] The invention belongs to the technical field of LED light sources for promoting plant growth, and in particular relates to an LED light source for promoting fruit fullness. Background technique [0002] People hope to irradiate plants with artificial light sources to meet the energy needed for the special purpose of plant growth. The specific types can be divided into: supplementing the intensity of natural light, prolonging the time of natural light irradiation, and completely replacing natural light. The light environment is one of the important physical environmental factors that are indispensable for the growth and development of plants. During the cultivation of agricultural greenhouses, due to climate change or poor light transmission of the greenhouses, the light intensity in the greenhouses cannot meet the requirements. The phenomenon required for plant growth, and plants have different requirements for light of different wavelengths in differe...
