Fluorescent powder composition for plant illumination florescent lamp

Abstract

The invention discloses a fluorescent powder composition for a plant lighting fluorescent lamp. The composition comprises the following components in weight percentage: 20 to 30 percent of Sr2PwO7:Eu, 50 to 70 percent of LiAlO2:Fe and 10 to 15 percent of MgO.MgF2CeO28:Mn. The fluorescent lamp made by the fluorescent powder composition of the invention has the advantages that: the spectrum is continuous and in line with the photosynthetic absorption spectrum, so that the fluorescent lamp is suitable for the cultivation of plants.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a fluorescent powder composition used for plant lighting fluorescent lamps. Background technique [0002] Under the action of light, carbon dioxide and water in plants produce carbohydrates, which are the basic nutrients for organic organisms. As shown in Figure 1, the light suitable for plant growth is blue-violet light of 400-500nm and red-orange light of 600-700nm. The photons have the highest probability of hitting chlorophyll, the strongest photochemical reaction ability, and the highest photosynthesis efficiency. Under normal circumstances, plants complete the above process through natural light irradiation, but off-season planting and indoor plants need auxiliary irradiation of special light sources to complete. [0003] Generally, the spectrum of fluorescent light source is discontinuous, the energy utilization rate of light source is not high, and the spectral curve an...

Problems solved by technology

[0005] The fluorescent powder composition disclosed in this patent has complex components, and the spectrum emitted by the prepared fluorescent lamp does not match the absorption spectrum of plant photosynthesis enough, which cannot promote plant photosynthesis to the greatest extent.
