A light emitting module includes a light source board having a first surface and a second surface opposing the first surface and extending from one end to the other end, forming a spiral shape; at least one light source disposed on the first surface of the light source board; and a heat dissipation plate disposed on the second surface of the light source board and provided with a contact surface having a spiral shape corresponding to that of the light source board.

Light emitting module

A method for selectively growing a nitride semiconductor, in which a mask is formed, with an opening formed therein, on a nitride semiconductor layer. A nitride semiconductor crystal is selectively grown on a portion of the nitride semiconductor layer exposed through the opening in the mask, the nitride semiconductor crystal shaped as a hexagonal pyramid and having crystal planes inclined with respect to a top surface of the nitride semiconductor. Here, the nitride semiconductor crystal has at least one intermediate stress-relieving area having crystal planes inclined at a greater angle than those of upper and lower areas of the nitride semiconductor crystal, the intermediate stress-relieving area relieving stress which occurs from continuity in the inclined crystal planes.
