Publication number: 20080164482Abstract: 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.Type: ApplicationFiled: April 27, 2005Publication date: July 10, 2008Inventors: Kunihiko Obara, Toshihide Maeda, Tadashi Yano, Noriyasu Tanimoto

Publication number: 20070228947Abstract: A luminescent light source includes: a light-emitting element (1); a substrate (2) including a conductor pattern (4); and a phosphor layer material (3) containing a phosphor and a light-transmitting base material. In the luminescent light source, the light-emitting element (1) is connected to a conductor pattern (4b), and the phosphor layer material (3) covers the light-emitting element (1). Further, at least the light-transmitting base material in the phosphor layer material (3) is disposed between the light-emitting element (1) and the substrate (2). Thus, a luminescent light source can be provided that allows a gap between a light-emitting element such as a LED bare chip or the like and a substrate to be eliminated, thereby obtaining output light with even chromaticity and achieving high luminous efficiency.Type: ApplicationFiled: October 11, 2005Publication date: October 4, 2007Applicant: MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD.Inventors: Noriyasu Tanimoto, Tadashi Yano, Kiyoshi Takahashi, Masanori Shimizu, Toshifumi Ogata
