Abstract
Disclosed herein is a light emitting diode package including a package body having a cavity, a light emitting diode chip having a plurality of light emitting cells connected in series to one another, a phosphor converting a frequency of light emitted from the light emitting diode chip, and a pair of lead electrodes. The light emitting cells are connected in series between the pair of lead electrodes.
Claims18
A light emitting diode package comprising:
- a package body comprising a cavity;
- a light emitting diode chip comprising a plurality of light emitting cells connected in series to one another;
- a phosphor to convert a frequency of light emitted from the light emitting diode chip;
- a pair of lead electrodes;
- and
- landing pads spaced apart from each other on a bottom surface of the cavity,
- wherein the light emitting cells are connected in series between the pair of lead electrodes,
- wherein the light emitting diode chip is disposed on a landing pad among the landing pads,
- wherein at least two landing pads are disposed on the bottom surface of the cavity, and
- wherein the package body comprises a lower dielectric substrate, an upper dielectric substrate stacked on the lower dielectric substrate, upper conductive patterns disposed on an upper surface of the upper dielectric substrate, middle conductive patterns disposed between the upper and lower dielectric substrates to be connected to the upper conductive patterns through upper vias, and lower conductive patterns disposed on a lower surface of the lower dielectric substrate to be connected to the middle conductive patterns through lower vias.
