LIGHT EMITTING DIODES WITH IMPROVED LIGHT COLLIMATION |
摘要 |
A light emitting diode with improved light collimation comprises a substrate-supported LED die disposed within a transparent dome. A portion of the dome laterally circumscribe the die comprises light reflecting material to reflect emitted light back to the die. A portion of the dome centrally overlying the die is substantially free of light reflecting material to permit exit of light within a desired radiation pattern. The LED die may be packaged for high temperature operation by disposing them on a ceramic-coated metal base which can be coupled to a heat sink. The packaged LED can be made by the low temperature co-fired ceramic-on-metal technique (LTCC-M). |
