Abstract

In a light emitting apparatus that includes a plurality of semiconductor light emitting devices 2 each having a light emitting face covered with a phosphor layer 3, a semiconductor assembly obtained by assembling a submount and the semiconductor light emitting devices is mounted on the substrate. Accordingly, chromaticity characteristics of the semiconductor assembly can be measured before the semiconductor assembly is mounted on the substrate. Therefore, even if using a plurality of semiconductor light emitting devices, a semiconductor assembly can be prepared on which the semiconductor light emitting devices each having uniform chromaticity characteristics are mounted before the semiconductor assembly is mounted on the substrate. And, a light emitting apparatus having suppressed dispersion of chromaticity can be manufactured.

Description

technical field [0001] The present invention relates to a light-emitting device including a plurality of semiconductor light-emitting elements and a substrate covering at least a part of a light-emitting surface with a phosphor layer, and a method of manufacturing the same. Background technique [0002] A conventional light-emitting device is a device in which a plurality of semiconductor light-emitting elements are mounted on a substrate, and the semiconductor light-emitting elements are covered with a resin containing a fluorescent substance. As such a conventional light emitting device, a light emitting device described in Patent Document 1 is known. [0003] The structure of a conventional light-emitting device will be described with reference to FIG. 1 . Fig. 1 is a conventional light-emitting device, Fig. 1(a) is a perspective view, and Fig. 1(b) is a partially enlarged cross-sectional view. [0004] As shown in Fig. 1 (a) and (b), the existing light-emitting device ...
