Abstract
Disclosed is an LED assembly having an omnidirectional light field. The LED assembly has a transparent substrate, LED chips, and first and second electrode plates. The transparent substrate comprises first and second surfaces facing to opposite orientations respectively. The transparent substrate has a via hole tunneling therethrough, which is formed with conductive material to provide a conductive via. The LED chips are mounted on the first surface. The first and second electrode plates are formed on the first and second surfaces respectively. The light emitting diode chips and the conductive via are electrically connected in series between the first and second electrode plates.
