Abstract
Provided is a light-emitting module that achieves high brightness, whose electrode structure is simple and whose brightness distribution has rotational symmetry. The light-emitting module includes a substrate, a first electrode and a second electrode disposed on the substrate, LED devices connected between the first electrode and the second electrode, a dam member disposed on the substrate so as to surround the LED devices, and a phosphor-containing resin for sealing the LED devices by being filled into a region surrounded by the dam member on the substrate. The first electrode includes a first outer electrode disposed under the dam member and a first inner electrode disposed nearer to a center of the substrate than the first outer electrode is. The second electrode includes a second outer electrode disposed under the dam member and a second inner electrode disposed nearer to the center of the substrate than the second outer electrode is. The first outer electrode is disposed so as to oppose the second inner electrode. The second outer electrode is disposed so as to oppose the first inner electrode.
