Abstract
Official abstract text for this publication.
A light-emitting device includes a light-emitting structure with a side surface, and a reflective layer covering the side surface. The light-emitting structure has a first light-emitting angle and a second light-emitting angle. The difference between the first light-emitting angle and the second light-emitting angle is larger than 15°.
First claim
Opening claim text (preview).
What is claimed is: 1 . A light-emitting device comprising: a light-emitting structure with a side surface; and a reflective layer covering the side surface; wherein the light-emitting device has a first light-emitting angle and a second light-emitting angle, and a difference between the first light-emitting angle and the second light-emitting angle is larger than 15°. 2 . The light-emitting device according to claim 1 , further comprising a light-transmitting body enclosing the light-emitting structure. 3 . The light-emitting device according to claim 2 , wherein the light-transmitting body has a top surface and a bottom surface opposite to the top surface, and the light-emitting device comprises a pair of extension electrode layers disposed on the bottom surface. 4 . The light-emitting device according to claim 2 , wherein the light-transmitting body has a first side surface, a second side surface, a third side surface and a fourth side surface, and the reflective layer covers the first side surface and the third side surface without covering the second side surface and the fourth side surface. 5 . The light-emitting device according to claim 4 , where the first side surface is opposite to the third side surface and the second side surface is opposite to the fourth side surface. 6 . The light-emitting device according to claim 1 , wherein the first light-emitting angle is of 130˜150°. 7 . The light-emitting device according to claim 1 , wherein the second light-emitting angle is of 100˜125°. 8 . The light-emitting device according to claim 1 , wherein the light-emitting device has merely three light-emitting surfaces. 9 . The light-emitting device according to claim 1 , further comprising an extension electrode layer overlapping the reflective layer. 10 . The light-emitting device according to claim 1 , further comprising an extension electrode layer having a side surface coplanar with the reflective layer. 11 . The light-emitting device according to claim 3 , wherein the reflective layer has an inner surface with a first portion inclined with respect to the top surface and a second portion substantially perpendicular to the top surface. 12 . The light-emitting device according to claim 11 , wherein the first portion has a height larger than that of the light-emitting structure.
