Abstract: 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°.

Abstract: A substrate includes a first metal layer, a second metal layer, a third metal layer and an insulation layer surrounding the first metal layer, the second metal layer and the third metal layer. The first power component is electrically connected to the first metal layer. The second power component is electrically connected to the second metal layer. The shortest distance between the first metal layer exposed to a second surface of the insulation layer and the second metal layer exposed to the second surface is a first distance, the shortest distance between a first metal layer of the insulation layer exposed to the first surface and the second metal layer exposed to the first surface is a second distance, and a ratio value of the first distance to the second distance ranges between 1.25 and 1.4.

Abstract: A light-emitting device includes a light-emitting structure with a side surface, and a reflective layer covering the side surface, and a light-transmitting body. The light-transmitting body encloses the light-emitting structure and has a first side surface, a second side surface, a third side surface and a fourth side surface. The reflective layer covers the first side surface and the third side surface without covering the second side surface and the fourth side surface. The light-emitting structure has a first light-emitting angle and a second light-emitting angle different from the first light-emitting angle.
