Patent number: 9634203Abstract: A light emitting device includes: a substrate having a main surface; a phosphor layer provided on the main surface and containing an LED element that emits primary light and a fluorescent particle that absorbs a part of the primary light and emits secondary light; and a transparent resin layer having a refractive index n and covering the phosphor layer. The transparent resin layer has an outer circumferential surface that forms a boundary between the transparent resin layer and the atmosphere. When a minimum circumference that includes the overall phosphor layer and is concentric with the outer circumferential surface has a radius r in a cut surface where at least a part of the outer circumferential surface takes a shape of an arc having a radius R, a relationship of R>r·n is satisfied. With such configuration, the light extraction efficiency is enhanced.Type: GrantFiled: May 29, 2009Date of Patent: April 25, 2017Assignee: SHARP KABUSHIKI KAISHAInventors: Shin Ito, Yutaka Okada, Takanobu Matsuo, Masayuki Ohta

Patent number: 8283675Abstract: There is provided a light emitting device which makes it possible to reduce optical loss and improve brightness by increasing a ratio of fluorescent light that is not reabsorbed by a light emitting element while decreasing a ratio of scattered light that is reabsorbed by the light emitting element. Individual faces forming outer faces of the light emitting element 2 are in contact with a bonding member 3 or sealing member 4. The bonding member 3 and the sealing member 4 contain a fluorophor. Emitted light emitted from the faces of the light emitting element 2 is transformed into fluorescent light by the fluorophor. Therefore, the ratio of scattered light that is not transformed from the emitted light into the fluorescent light can be decreased while the ratio of fluorescent light is increased.Type: GrantFiled: April 9, 2010Date of Patent: October 9, 2012Assignee: Sharp Kabushiki KaishaInventors: Masayuki Ohta, Takanobu Matsuo, Masahiro Konishi, Tomoshi Kimura
