20100230693 | White light emitting diode package and method of making the same - A white light emitting diode (LED) package with multilayered encapsulation structure and the packaging methods are disclosed. The white LED package structure includes metal electrodes, a heat dissipation base, a PPA plastic for fixing the electrodes and the heat dissipation base together, at least one LED die, a die attaching material, gold wires for electrically connecting the LED die to the electrodes, a first type of silicone encapsulant, a second type of silicone encapsulant, and a phosphor containing layer. The invention utilizes a low-refractive index silicone (the second type of silicone encapsulant) to separate the phosphor containing layer away from the first type of silicone, which covers the LED die, to prevent/reduce emitted light going backward and hitting the LED die. | 09-16-2010 |
