Abstract
A solar spectrum-like LED structure, comprising a negative electrode for a three-dimensional integrated package, and a plurality of LED chips and resistors. The negative electrode for a three-dimensional integrated package is a three-dimensional structure comprising a plurality of planes. The plurality of LED chips is installed on the plurality of planes of the negative electrode for the three-dimensional integrated package. Light of different colors emitted by the plurality of LED chips forms a plane light source or a cone light source after being well mixed at an intersection point, thus simulating a solar spectrum. The invention enables manufacturing of a solar spectrum-like LED fluorescent lamp suitable for generating different bands of spectrums for the survival and metabolism of various organisms. In addition, the solar spectrum-like LED fluorescent lamp has a good color-rendering property and visual effect, and can be widely applied in the fields of general lighting, agriculture, animal husbandry and new biological energy sources.
