摘要:
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.
