Abstract

Heavily phosphor loaded LED packages having higher stability and a method for increasing the stability of heavily phosphor loaded LED packages. The silicone content of the packages is increased by decreasing the amount of one phosphor of the blend or by increasing the thickness of the silicone phosphor blend layer.

Claims (4)

1. A heavily phosphor loaded LED package having improved color stability, comprising:

an LED and a silicone phosphor blend encapsulating the LED, wherein the silicone phosphor blend includes silicone in an amount of about 53 wt %, PFS phosphor in an amount of about 36 wt %, and BSY phosphor in an amount of about 11 wt %.

2. The LED package of claim 1 , wherein the LED is a mid power LED, and the silicone phosphor blend is highly loaded with a BSY-PFS phosphor.

3. The LED package of claim 1 , wherein the silicone phosphor blend provides at least a 25% improvement in color shift.
