A light emitting diode assembly includes a supporter and a plurality of light emitting diodes, the supporter having a light emitting diode region, the light emitting diode region defining a plurality of concentric circles with radiuses R<SUB>n </SUB>thereof satisfying the equation: R<SUB>n</SUB>=nxr, where r represents a radius of the smallest circle, and n represents a sequence number of the circles in order from the smallest circle to the largest circle. The light emitting diodes are arranged in the light emitting diode region of the supporter, wherein, a number of light emitting diodes m are arranged in the smallest circle of the light emitting diode region of the supporter, and a number of light emitting diodes equaling (2n-1)xm are arranged in a circular region bounded by the circle number (n-1) and the circle number n of the supporter.
