摘要:
A light-emitting apparatus including: a substrate; an LED chip mounted on a first surface of the substrate; a fluorescent material-containing layer containing a first fluorescent material, which fluorescent material-containing layer is provided above the first surface of the substrate so as to cover the LED chip; and a color-adjusting fluorescent layer that contains a second fluorescent material, which color-adjusting fluorescent material layer is formed in a layer provided on an outer side of the fluorescent material-containing layer in an emission direction, the color-adjusting fluorescent layer being formed in dots. Thus, the present invention provides a light-emitting apparatus and a method for manufacturing the same, each making it possible to carry out fine color adjustment so as to prevent a subtle color shift that occurs due to a factor such as a difference in concentration of a fluorescent material or the like.
