Abstract
A light emitting device includes a substrate, a plurality of LEDs arranged in rows and columns above the substrate, and a wavelength converting member above the plurality of LEDs. The wavelength converting member includes a plurality of fluorescent portions arranged in rows and columns and a lattice-shaped light shielding portion between the plurality of fluorescent portions. One or more row-direction spacing regions are located directly below a corresponding one of the rows of the fluorescent portions, and one or more column-direction spacing regions are located directly below a corresponding one of the columns of the fluorescent portions. One or more row-direction light-shielding regions of the light-shielding portion are respectively located directly above a corresponding one of the rows of the LEDs, and one or more column-direction light-shielding regions of the light-shielding portion are respectively located directly above a corresponding one of the columns of the LEDs.
