Full spectrum system

A full-spectrum device of the full-spectrum system comprises at least three paths of light-emitting units corresponding to different source color temperature nodes, and a control unit controls the input power proportion of each light-emitting unit; the average ASD value of the full-spectrum device under each source color temperature node is smaller than 25%, the average Rf value is larger than 85, and the average Ra value is larger than 90, so that the full-spectrum device is good in spectrum continuity, low in blue light peak value and high in similarity with natural light; in the CI E coordinate system, each source color temperature node satisfies the following conditions: the linear distance L1 between the two source color temperature nodes with the maximum color temperature value and the minimum color temperature value is greater than or equal to 0.04 so as to ensure the color temperature modulation width; the linear distances between the adjacent source color temperature nodes are equal so as to ensure t
