Embodiment Construction
[0039] Now, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0040]As shown in FIG. 5 , a surface light source 1 using LEDs for reducing color speckle includes a plurality of light source beams 10 arranged along a first direction and a second direction. Each of the light source bundles 10 consists of green GLEDs, red R LEDs and blue B LEDs arranged in a triangle. The surface light source 1 also comprises a first array 20 of beams 10 arranged in rows along a first direction and inverted alternately with respect to the first direction.
[0041] As shown in FIG. 5 , the x-axis is assumed to be the first direction, and the y-axis is assumed to be the second direction.
[0042] Therefore, the plurality of light source beams 10 arranged in the first array 20 are arranged in a row along the first direction x-axis and alternately inverted with respect to the first direction.
[0043] Thus, assume that the first...
