Abstract
An LED package assembly comprising two or more light emitting diode dies within an epoxy housing such that a wider light emitting angle with a higher light intensity everywhere around the package including its bottom part is obtained. The LED package can be a substitute for bulb illumination or serving some decorative functions. Furthermore, the LED has low power consumption, a tough body and a long working life. Moreover, a cluster of these LEDs in a large display screen is capable of enhancing clarity of vision and the range of observation from a few meters to a few kilometers away.
Claims30
A packaging design for light emitting diodes comprising:
- an epoxy housing;
- a plurality of light emitting diode dies;
- a plurality of metallic pins;
- a plurality of flat panel bases a the upper end of the metallic pins for mounting the light emitting diode dies wherein the plurality of flat panel bases include conical or hemi-ellipsoid reflecting mirrors;
- and
- a plurality of metallic wires for connecting a terminal of the light emitting diode die to the metallic pin.
A light emitting diode cluster formed by clustering a plurality of light emitting diodes serving as a lamp or big display screen, wherein the light emitting diode package comprises:
- an epoxy housing;
- a plurality of light emitting diode dies;
- a plurality of metallic pins;
- a plurality of flat panel bases a the upper end of the metallic pins for mounting the light emitting diode dies wherein each of the plurality of light emitting diode dies and the plurality of flat panel bases are located so as to face in a different direction;
- and
- a plurality of metallic wires for connecting a terminal of the light emitting diode die to the metallic pin.
