Lighting device topology for reducing unevenness in LED luminance and color

A lighting device comprising:

• a plurality of solid-state light emitting elements;
• a first translucent resin layer arranged to cover the plurality of solid-state light emitting elements;
• a light converting member positioned to cover an outer surface of the first translucent resin layer, and contains a phosphor that converts a wavelength of emission light of the plurality of solid-state light emitting elements;
• and
• a light diffusion member that is formed between the plurality of solid-state light emitting elements and is effective to diffuse the light emitted from the plurality of solid-state light emitting elements,
• the light diffusion member further comprising a diffusion degree that is increased toward an intermediate position between mutually adjacent solid-state light emitting elements, and is decreased toward each of the individual solid-state light emitting elements.
