发明名称 SEMICONDUCTOR LIGHT EMITTING ELEMENT AND LIGHT EMITTING DEVICE PROVIDED WITH THE SAME
摘要 <P>PROBLEM TO BE SOLVED: To provide a light emitting device having reduced loss of light to be absorbed by a pad electrode and also improved characteristic thereof. <P>SOLUTION: In the light emitting device 30 including a semiconductor light emitting element 1 and a wavelength converting member such as a phosphorus material or the like, reflecting layers 10c, 20c are provided on the outermost surface layers of a type p pad electrode 10a and a type n pad electrode 20a provided on the same surface side of the semiconductor light emitting element 1. Accordingly, the output light L emitted from a light emitting layer 4 of the semiconductor light emitting element 1 is capable of guiding a returning light having changed the traveling direction toward the semiconductor light emitting element 1 through reflection by a phosphorus material to the light visualizing side with the reflecting layers 10c, 20c of the pad electrode. Namely, absorption of light by the semiconductor light emitting element can be reduced to improve light extracting efficiency of the light emitting device. <P>COPYRIGHT: (C)2008,JPO&INPIT
