Abstract: A light-emitting chip includes a light-emitting unit, first and second electrode units. The light-emitting unit includes first and second conductivity type semiconductor layers and an active layer. The first electrode unit includes two first electrodes which are spaced apart from each other by a first distance, and which are electrically connected to the first conductivity type semiconductor layer. The second electrode unit includes two second electrodes electrically connected to the second conductivity type semiconductor layer. The first and second electrode units are spaced apart from each other by a second distance, and the first distance is greater than the second distance.

Abstract: A light emitting diode includes a semiconductor layer sequence stack, a reflective polarizing layer and a diffuse reflection structure. The semiconductor layer sequence stack includes first and second semiconductor layers, and a light emitting layer disposed therebetween. The reflective polarizing layer is disposed on the semiconductor layer sequence stack. The diffuse reflection structure is disposed on the light emitting layer opposite to the reflective polarizing layer. A light emitting device including the light emitting diode, and a projector including the light emitting device are also provided.

Abstract: A light-emitting diode includes an epitaxial layered structure, a reflective layered unit, and a light-transmissive structure. The epitaxial layered structure has opposite upper and lower surfaces and a side surface interconnecting the upper and lower surfaces. The reflective layered unit is disposed on the lower surface of the epitaxial layered structure. The light-transmissive structure covers the upper surface of the epitaxial layered structure and a portion of the side surface of the epitaxial layered structure, and is configured to allow light emitted from the epitaxial layered structure to exit therefrom at a light-exit angle of not smaller than 125°.
