    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.

    摘要: A light emitting device including a phosphor blend including four or more phosphors emitting within a specific spectral range to optimize the color rendering index (CRI) for a given color coordinated temperature (CCT). The blend will include at least four phosphors selected from the following: a blue phosphor having an emission peak at 400-500 nm, a green phosphor having an emission peak at 500-575 nm, an orange phosphor having an emission peak from 575-615 nm, and a deep red phosphor having an emission peak at 615-680 nm. The preferred blends are used to make light sources with general CRI values (Ra) greater than 95 at CCT's from about 2500 to 8000 K.

    摘要: A light emitting package (8, 8′, 8″, 208, 408) includes a printed circuit board (10, 10′, 10″, 210, 410) supporting at least one light emitting die (12, 12″, 14, 16, 212, 412). A light transmissive cover (60, 60′, 60″, 260, 460) is disposed over the at least one light emitting die. The cover has an open end defining a cover perimeter (62, 62′, 62″, 262, 462) connected with the printed circuit board. An inside surface of the cover together with the printed circuit board defines an interior volume (70, 70″, 270, 470) containing the at least one light emitting die. An encapsulant (76, 76″, 276, 278, 476) is disposed in the interior volume and covers at least the light emitting die.
