Abstract
A light source module includes a module substrate, a metal conductor, a plurality of semiconductor light emitting elements, a white diffuse reflection layer, and translucent sealing members. The metal conductor is provided in a predetermined pattern on a front surface of the module substrate. The semiconductor light emitting elements are electrically connected to the metal conductor and mounted on the front surface of the module substrate. The white diffuse reflection layer includes a plurality of holes in which the semiconductor light emitting elements are located, is thinner than the semiconductor light emitting elements, and is laminated to the front surface of the module substrate. The translucent sealing members bury the semiconductor light emitting elements, project below the diffuse reflection layer, and are mixed with a phosphor.
