Abstract
A light-emitting apparatus having an LED-mounting surface having an improved light reflective efficiency is provided. The light-emitting apparatus includes a board, a first reflective layer arranged on the board, a second reflective layer different from the first reflective layer, arranged at a position different from the position of the first reflective layer on the board, a first configuration configured by a first LED element mounted on the first reflective layer and a first phosphor-containing resin which protects the first LED element and transforms a wavelength of light emitted from the first LED element, and a second configuration configured by a second LED element mounted on the second reflective layer and a second phosphor-containing resin which protects the second LED element and transforms a wavelength of light emitted from the second LED element. A reflective efficiency of the first reflective layer for first light emitted from the first configuration is higher than a reflective efficiency of the second reflective layer for the first light.
