| Title: |
Light Source and Illuminating Device |
| Abstract: |
A light source comprises a light emitting diode array (101) and a
collimator array (102). The light emitting diode array (101) comprises at
least two light emitting diode units (101a, 101b) that emit light of
different colors; the collimator array (102) is used for collimating
light emitted by the light emitting diode units (101a, 101b) and keep the
optical extension of the light emitted by the light emitting diode units
(101a, 101b) substantially unchanged. The light source further comprises
a dodging device (103) used for dodging light emerging from the
collimator array (102). An illuminating device comprises the light
source. The light emitting diode units (101a, 101b) and the collimator
unit (102a) in the light source and the illuminating device minimize the
optical extension of the emergent light, thereby maximizing the
luminance.
