Abstract

The invention discloses a full-spectrum light-emitting diode and an application thereof. A fluorescent powder composition is mixed with silica gel; in the mixture of the fluorescent powder composition and the silica gel, at least two blue LED chips are coated with the mixture of the fluorescent powder composition and the silica gel; the blue LED chips are blue light-emitting diode chips; the fluorescent powder composition comprises at least two kinds of fluorescent powder with different colors; an excited spectra are an approximate plant photosynthesis curve, a meat exposure curve, a biological growth curve, a seafood exposure curve, a fruits and vegetables exposure curve and a pastry exposure curve; a light source of the full-spectrum light-emitting diode can be adjusted to simulate natural light exposure; and the excited spectra are close to the approximate plant photosynthesis curve, so that photosynthesis is carried out on a plant; and the best plant growth effect, the best fresh effect of meat exposure, the best fresh effect of seafood exposure, the best fresh effect of fruits and vegetables exposure and the best delicious effect of pastry exposure can be achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of light source allocation, in particular to a full-spectrum light-emitting diode and its application. 【Background technique】 [0002] Full-spectrum light-emitting diodes simulate the spectrum of natural light, which contains the spectrum required for plant growth. Its characteristics have been studied and proved that under different light intensity, spectrum and photoperiod conditions, there are different requirements for the growth of plants. And conditions, and the most important photosynthesis has a great impact on green plants. The efficiency of light sources on plant photosynthesis has been studied by American and Japanese scholars. It is the most suitable for the spectrum. The more suitable the light source for plant growth is in line with its most suitable spectrum. , the greater the benefit to plant photosynthesis. At present, the full spectrum is mainly used in the field of LED lighting, and the ...
