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: An illumination device includes at least one semiconductor light emitting element, a supporting base, and a lamp housing. The semiconductor light emitting element is disposed on the supporting base. The lamp housing is disposed on the supporting base to cover the semiconductor light emitting element, and includes a first illuminating part and a lateral illuminating part surrounding the first illuminating part. A micro-structure is formed on a side of the first illuminating part and facing the semiconductor light emitting element for reflecting the light emitted from the semiconductor light emitting element.

Abstract: A semiconductor light emitting element includes a transparent substrate and a plurality of light emitting diode (LED) chips. The transparent substrate has a support surface and a second main surface disposed opposite to each other. At least some of the LED structures are disposed on the support surface and form a first main surface where light emitted from with a part of the support surface without the LED structures. Each of the LED structures includes a first electrode and a second electrode. Light emitted from at least one of the LED structures passes through the transparent substrate and emerges from the second main surface. An illumination device includes the semiconductor light emitting element and a supporting base. The semiconductor light emitting element is disposed on the supporting base, and an angle is formed between the semiconductor light emitting element and the supporting base.

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.
