Abstract
Disclosed is an LED assembly having an omnidirectional light field. The LED assembly has a transparent substrate with first and second surfaces facing to opposite orientations respectively. LED chips are mounted on the first surface and are electrically interconnected by a circuit. A transparent capsule with a phosphor dispersed therein is formed on the first surface and substantially encloses the circuit and the LED chips. First and second electrode plates are formed on the first or second surface, and electrically connected to the LED chips.
