Abstract
A light-emitting device of an embodiment of the present application comprises light-emitting units; a transparent structure having cavities configured to accommodate at least one of the light-emitting units; and a conductive element connecting at least two of the light-emitting units.
Claims20
A light bulb, comprising:
- a first optoelectronic unit and a second optoelectronic unit, each optoelectronic unit comprising:
- a light-emitting structure comprising a side surface, a first semiconductor layer, a second semiconductor layer, and a light-emitting layer formed between the first semiconductor layer and the second semiconductor layer;
- and
- a first bonding pad and a second bonding pad formed on the first semiconductor layer;
- a conductive element connecting the first bonding pad of the first optoelectronic unit and the second bonding pad of the second optoelectronic unit, without covering the side surfaces of the first optoelectronic unit and the second optoelectronic unit;
- a transparent structure, pervious to light from the light-emitting structure, and continuously covering the light-emitting structures and the conductive element, and having a curved surface;
- a first terminal and a second terminal electrically connecting the first optoelectronic unit and the second optoelectronic unit, and formed on a same side of the transparent structure;
- and
- a cover covering the first optoelectronic unit, the second optoelectronic unit, the conductive element, and the transparent structure.
