Wherein, by limiting the range of spectral energy ratio of the light formed by each wavelength segment between curve A and curve B, the spectral energy ratio range corresponding to each wavelength is narrowed, that is, the Y-axis difference between curve A and curve B corresponding to each wavelength is greatly reduced compared with the prior art, thereby reducing the difficulty of secondary light distribution, and further guiding the production of the light source more conveniently and reasonably.

[0042] Referring to Figure 6 In some embodiments, curve A is formed by sequentially connecting the coordinate points (361, 0.1), (380, 0.1), (400, 0.15), (440, 0.3), (455, 0.33), (478, 0.35), (520, 0.5), (556, 0.6), (620, 0.7), (640, 0.75), (660, 0.8), (698, 0.99), (711, 1), (725, 0.98), (739, 0.99), (755, 1), (765, 0.99), (800, 0.5), (850, 0.3);
