LED array
An LED array includes a plurality of first and second light-emitting rows. Each of the first light-emitting rows is composed of a plurality of red and green LEDs arranged linearly alternately. Each of the second light-emitting rows is composed of a plurality of green and blue LEDs arranged linearly alternately. The first and second light-emitting rows are parallel to each other and arranged alternately. Thus, the LED array can generate preferably equable arrangement of colored light to output preferably equable light mixture. In any 2×2 matrix, there are two green, one red, and one blue LEDs.
