Abstract
An LED assembly includes 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.
Claims10
A light-emitting diode assembly, comprising:
- a substrate, comprising:
- a top surface;
- a bottom surface opposite to the top surface;
- and
- a terminal portion;
- a first electrically-conductive strip, located on the top surface;
- a second electrically-conductive strip, located on the top surface, separated from the first electrically-conductive strip, and closer to the terminal portion than the second electrically-conductive strip;
- a light-emitting diode chip, flipped to mount on the first electrically-conductive strip and the second electrically-conductive strip;
- a transparent body, comprising a phosphor, located on the top surface, and covering the light-emitting diode chip and the first electrically-conductive strip;
- a first electrode plate, located on the second electrically-conductive strip and electrically connected to the light-emitting diode chip;
- and
- a phosphor layer, located under the bottom surface.
