Abstract
An LED lamp bead structure having a quasi-solar spectrum, comprising a first polar electrode (10), a plurality of LED chips (20), a plurality of resistors (30) and a circuit board (40); the first polar electrode (10) is in cooperation with the circuit board (40) to package the plurality of LED chips (20) and the plurality of resistors (30); the structure of the first polar electrode (10) is a three-dimensional structure comprising a plurality of planes, which freely simulates the solar spectrum and may take the most advantage of the energy-saving feature of LED semiconductors.
