摘要： When viewed in parallel to a central axis (C1), three LED substrates (4) form an equilateral triangle (T) that surrounds the central axis (C1) and are disposed equidistantly with respect to the central axis (C1). When viewed in parallel to the central axis (C1), LEDs (8) are disposed on an outer surface (4a) of each LED substrate (4) at least one each at each of a pair of placement positions (Q1) at both sides sandwiching a reference normal (BN) being a normal to the outer surface (4a) and passing through the central axis (C1). The LEDs (8) each have an optical axis (8a) orthogonal to the outer surface (4a). When viewed in parallel to the central axis (C1), radiated lights from the LEDs (8) at the pair of placement positions (Q1) of each LED substrate (4) are, by an optical system (K), converted to and emitted as emitted parallel lights (RPL) that are respectively parallel to a pair of light emission reference lines (RB) passing through the central axis (C1) at both sides sandwiching the reference normal (BN) and respectively contain the corresponding light emission reference lines (RB).

摘要： 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.
