A light source includes first to nth light emitting modules (n is a natural number that is two or more than two) each having a plurality of light emitting elements and connectors that are electrically connected to the light emitting elements. The connector of the first light emitting module is disposed near an angular point (hereinafter, referred to as 'rotational central point') of a region defining the first light emitting module. The light emitting elements and connector of the ilight emitting module has a layout structure defined by a clockwise or counter-clockwise rotation of the light emitting elements and connectors of the first light emitting module by an angle (i&#x2212;1)/n&#xd7;360&#xb0; about the rotational central point, wherein i is a natural number which satisfies 2&#x2266;i&#x2266;n.
