Patent number: 11404614Abstract: Provided is a light-emitting device having a plurality of light-emitting elements with high operation stability and light extraction efficiency. The light-emitting device includes: a light-emitting element; a translucent member which is disposed on the light-emitting element and has a columnar first portion having a bottom surface opposed to an upper surface of the light-emitting element, a second portion formed continuously with the first portion on the first portion and narrowed upward, and a columnar third portion formed continuously with the second portion on the second portion; and a reflective member configured to cover the side surfaces of the translucent member. In this light-emitting device, the height of the first portion of the translucent member in a direction perpendicular to the bottom surface thereof is ? or more the height of the translucent member in the direction perpendicular to the bottom surface.Type: GrantFiled: May 15, 2020Date of Patent: August 2, 2022Assignee: STANLEY ELECTRIC CO., LTD.Inventors: Kyotaro Koike, Ji-Hao Liang, Mitsunori Harada, Kaori Tachibana, Shunya Ide, Hiroshi Kotani, Satoshi Ando
