Light source module and lighting apparatus

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.
