Abstract
The present invention discloses a light source with uniform chromaticity and luminance and a color sensor having the same. The light source includes multiple LED devices, a primary light guide plate assembly and a secondary light guide plate assembly. The chromaticity and luminance of light emitted from the LED devices are uniformized for the first time in the primary light guide plate assembly and then guided into the secondary light guide plate assembly for the secondary chromaticity and luminance uniformization, to thereby act as the light source of the color sensor. Therefore, the light source not only provides better chromaticity and luminance uniformization effects, but is further qualified as the standard illuminant D65, thereby enabling more precise color sensor inspection results.
