  • RGB LED package with BSY emitter
    Patent number: 12100693
    Abstract: LED packages are disclosed capable of emitting a range of colors including white light, while still emitting that can have a high color rendering index (CRI). The LED packages can have a simplified reflective cup arrangement and improved lead frame design. The LED packages according to the present invention comprise one or more LED WITH PHOSPHORs for high CRI lighting applications, along with multiple narrowband emitters (e.g. RGB LEDs), but do not have a dam or partition to segregate the LED WITH PHOSPHOR from the multiple emitters. This results in a LED package that is less complex and easier to manufacture, while still providing the desired flexibility in LED package emissions.
