    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.

    摘要: A directional lamp comprises a light source, a beam forming optical system configured to form light from the light source into a light beam, and a light mixing diffuser arranged to diffuse the light beam. The light source, beam forming optical system, and light mixing diffuser are secured together as a unitary lamp. The beam forming optical system includes: a collecting reflector having an entrance aperture receiving light from the light source and an exit aperture that is larger than the entrance aperture, and a lens disposed at the exit aperture of the collecting reflector, the light source being positioned along an optical axis of the beam forming optical system at a distance from the lens that is within plus or minus ten percent of a focal length of the lens.
