24. The light emitting diode package according to claim 22, wherein the metal inclusion comprises a coating material or a metal paste.
FIG. 2 illustrates an LED lead frame structure disclosed in U.S. Patent Application Publication No. 2004/0075100. FIG. 2 depicts a lead frame 2 and a heat conducting part 4. The lead frame 2 is separated into two electric connecting parts 12 a and 12 b, which are connected to respective solder connecting strips 3 a and 3 b.
The first electric connecting part 12 a has an eye-shaped opening into which the heat conducting part 4 is inserted. The heat conducting part 4 is substantially rotationally symmetric and has protrusions formed thereon to ensure the lead frame is solidly fixed inside a housing. The heat conducting part 4 has a recess formed in the center thereof to serve as a reflector 16. Also, on a bottom surface of the heat conducting part 4, a chip mounting area 11 is provided to support a light releasing chip, which is the LED chip. A side of the recess functions as a reflecting surface.
The LED package 100-3 of this embodiment is distinct from the aforesaid LED package 100 only in that a recess 114-3 of a heat conducting part 110 is formed of only an upper sheet metal 112 in the LED package 100-3. That is, in the aforesaid LED package 100, the hole is perforated in the upper sheet metal 112 a to form the recess 114 so that an upper surface of the lower sheet metal 112 b partially constitutes a bottom surface of the recess 114. But according to this embodiment, a concave is formed in a predetermined area of an upper surface of an upper sheet metal 112 a via cutting, punching or pressing to obtain a recess 114-3 so that the recess 114-3 is comprised of only the upper sheet metal 112 a.
The LED package 100-3 has the other constructions and effects substantially identical to those of the LED package 100 described above. Therefore the same or corresponding components were given the same reference signs and will not be explained further.
