Patent ID: 8408724

Claim:
A light source module comprising: a module substrate; a metal conductor provided in a predetermined pattern on a front surface of the module substrate; a plurality of semiconductor light emitting elements electrically connected to the metal conductor and mounted on the front surface of the module substrate; a white diffuse reflection layer comprising a plurality of holes in which the semiconductor light emitting elements are located, being thinner than the semiconductor light emitting elements, and laminated to the front surface of the module substrate; and translucent sealing members burying the semiconductor light emitting elements and mixed with a phosphor, each of the sealing members having substantially spherical shape with a radius greater than a height, the spherical shape defined by a diameter-to-height ratio, wherein when the height is 1 the diameter is in a range from greater than 2.0 to 7.8, wherein at least top portions of the sealing members project from the diffuse reflection layer, and distal ends of the semiconductor light emitting elements project from the diffuse reflection layer.
