Abstract
A light source comprises a light emitting diode array () and a collimator array (). The light emitting diode array () comprises at least two light emitting diode units () that emit light of different colors; the collimator array () is used for collimating light emitted by the light emitting diode units () and keep the optical extension of the light emitted by the light emitting diode units () substantially unchanged. The light source further comprises a dodging device () used for dodging light emerging from the collimator array (). An illuminating device comprises the light source. The light emitting diode units () and the collimator unit () in the light source and the illuminating device minimize the optical extension of the emergent light, thereby maximizing the luminance.
