Patent ID: 8511857

Claim:
A planar light source comprising: first to n th light emitting modules, n is a natural number that is two or more than two, each having a plurality of light emitting elements and a connector that is electrically connected to the light emitting elements, wherein the connector of the first light emitting module is disposed near an angular point, which is a rotational central point, of a region defining the first light emitting module; and the light emitting elements and connector of the i th light 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−1)/n×360° about the rotational central point, wherein i is a natural number which satisfies 2≦i≦n, wherein the connectors of the respective first to n th light emitting modules are disposed near the rotational central point, respectively, and supply electric power to the plurality of light emitting elements of the respective first to nth light emitting modules, and the connectors of the respective first to n th light emitting modules disposed near the rotational central point are separated from each other without being connected to each other through the respective connectors when the first to n th light emitting modules are connected to each other side-by-side to form the planar light source.
