High power light emitting diode package and method of producing the same
View Patent ↗A high power Light Emitting Diode (LED) package and a method of producing the same. The high power LED package according to the present invention includes a plurality of light emitting diode chips, a first lead frame with the light emitting diode chips mounted thereon, and a second lead frame disposed at a predetermined interval from the first lead frame. The LED package also includes a package body fixing the first and second lead frames and bonding wires for electrically connecting the plurality of LED chips. The package body includes at least one first reflecting part separately surrounding each of the plurality of LED chips with upward-inclined inner side walls thereof and a second reflecting part surrounding the entire plurality of LED chips with an upward-inclined inner side wall thereof.
1. A high power light emitting diode package comprising:
a plurality of light emitting diode chips;
a first lead frame with the plurality of light emitting diode chips mounted thereon and a second lead frame disposed apart at a predetermined interval from the first lead frame;
a package body fixing the first and second lead frames; and
bonding wires for electrically connecting the plurality of light emitting diode chips,
wherein the package body comprises at least one first reflecting part separately surrounding each of the plurality of light emitting diode chips with upward-inclined inner side walls thereof, and a second reflecting part surrounding the entire plurality of light emitting diode chips with an upward-inclined inner side wall thereof.
2. The high power light emitting diode package according to claim 1 , wherein the first lead frame comprises a planar base and an extension extending from an edge of the base.
3. The high power light emitting diode package according to claim 2 , wherein the package body exposes a portion of undersurface of the base of the first lead frame.
4. The high power light emitting diode package according to claim 1 , further comprising a resin encapsulant for encapsulating the plurality of light emitting diode chips.
5. The high power light emitting diode package according to claim 4 , wherein the resin encapsulant comprises one selected from the group consisting of a silicone-based resin, an epoxy resin, a urethane-based resin and mixtures thereof.
6. The high power light emitting diode package according to claim 4 , wherein the resin encapsulant comprises phosphor.
7. The high power light emitting diode package according to claim 1 , wherein the bonding wires extend over upper parts of the first reflecting part to electrically connect the adjacent ones of the light emitting diode chips.
