    Abstract: A method for the manufacturing of white LEDs is proposed, which can achieve a tunable color rendering index (CRI) or luminosity through the use of at least two phosphor composition layers of essentially the same emission color coordinates, each composition including at least one individual phosphor compound. The method allows to optimize the devices for CRI at a given minimal luminosity requirement, or vice versa.

    Abstract: A white light hybrid illumination system including an amber LED, a red LED, and a phosphor converted LED such as a blue LED chip and a green phosphor, wherein a peak emission difference between the amber and red LED is at least 25 nm. This system provides higher color quality than prior devices due to its high luminous efficacy, high CRI over a wide CCT range, and better color control.
