Wide-blue spectrum excited full-spectrum plant growth lighting lamp bead

Abstract

The invention discloses a wide-blue spectrum excited full-spectrum plant growth lighting lamp bead which comprises a lamp bead bracket and a chip group, wherein the chip group is formed by multiple chips with different light-emitting wavelengths; the chip group comprises a blue-violet LED chip and a blue LED chip; the blue-violet LED chip and the blue LED chip are packaged on the lamp bead bracket through multi-chip die bonding; composite fluorescent powder coats the outside of the chip group; and the composite fluorescent powder comprises combination of two or more of YAG, LuYAG, GaYAG, nitric oxide and nitride fluorescent powder. A wide-blue spectrum structure and a blue light-excited spectrum structure for emitting light through the fluorescent powder can fully meet the requirement of promoting facilitation of plants at flowering and fruiting stages through the wave bands of spectrums absorbed by the growth elements, such as chlorophyll and carotenoid, in plant growth when the lamp bead is electrified.

Description

technical field [0001] The invention relates to a supplementary light lamp bead used in the flowering and fruiting period of plants, in particular to a full-spectrum plant growth supplementary light lamp bead excited by a wide blue light spectrum. Background technique [0002] Sunlight is a necessary condition for green plants to realize photosynthesis and promote growth, and all stages of plant growth need light. Under normal circumstances, plants generally absorb light and energy of appropriate wavelengths from sunlight to achieve photosynthesis. Many types of green plants are vegetables and fruits that people eat daily. In modern agriculture, a large number of vegetables and fruits need to be planted to meet the huge demand of people. The artificially synthesized LED spectrum can effectively promote the growth of plants, improve the quality of growth, shorten the growth cycle, and regulate the growth rhythm. In order to avoid the impact of changes in the natural environ...

AI Technical Summary

Problems solved by technology

In order to avoid the impact of changes in the natural environment on plant growth, people plant vegetables and fruits in a closed environment and provide simulated sunlight to plants through artificial light sources. However, the light emitted by ordinary fluorescent lamps cannot fully satisfy The light environment required for the growth of most plants, especially the light environment that cannot meet the needs of plants during the flowering and fruiting period
