发明名称 Light emitting module and lighting device
摘要 <p>A light emitting module according to one embodiment includes a substrate (3); a light emitting body (5) disposed on the substrate (3); and a phosphor layer (9) having a first phosphor (15) and a second phosphor (17) which are excited by emitted light of the light emitting body (5). The first phosphor (15) has a light emitting peak whose half-value width is 20 nm or less in a wavelength range from 610 nm to less than 650 nm, and the second phosphor (17) has the light emitting peak in the wavelength range between a peak wavelength of a light emitting spectrum of the light emitting body (5) and the peak wavelength of the light emitting spectrum of the first phosphor (15). Then, a distribution of the first phosphor (15) in the phosphor layer (9) has density gradient, where the density of the first phosphor (15) increases toward at least one end of the phosphor layer (9) in a direction perpendicular to the substrate (3).</p>
