    摘要: A light source having a first die with an LED thereon, a substrate, a base layer and a first phosphor layer is disclosed. The first die is characterized by a top surface, a bottom surface and a light generation region at a height above the bottom surface. The substrate includes a depression in which the first die is mounted. The base layer fills the depression in the substrate to a height greater than half the distance from the bottom surface of the first die to the top surface of the first die and less than the light generation height of the first die. The first phosphor layer includes a first light converting material that converts light emitted by the first die to light of a different wavelength. The first phosphor layer is in direct contact with the base layer and covers the first die.

    摘要: A lighting apparatus is described. One embodiment of the lighting apparatus includes a substrate and a lighting element. The lighting element is coupled to the substrate to emit light through a light exit plane. The light exit plane is substantially perpendicular to the substrate. By providing a lighting device with a substrate oriented perpendicular to the light exit plane of the lighting device, the lighting device can enable better mixing of the light from different LEDs. The lighting apparatus facilitates light mixing, generally, to minimize or eliminate dark spots on the diffusion panel. The lighting device also facilitates color mixing to produce relatively consistent white light on the diffusion panel.

The bottom layer has a first surface adjacent to the insulating substrate and a second surface includes a portion of a bottom surface of the light source, the substrate having a die bonding region in which the top conducting layer and a portion of the substrate are absent. A portion of the bottom conducting layer is present under the die bonding region and the die is bonded to the top surface of the bottom conducting layer in the die bonding region.

    摘要: A light source having a light pipe and a light generation section. The light pipe includes a two-dimensional sheet of transparent material having a transparent top surface that is substantially parallel to a reflective bottom surface. The light pipe includes light pipe scattering centers that cause light traveling in the sheet of transparent material to be scattered in directions that allow some of the scattered light to escape the sheet through the top surface. The light generating section includes a plurality of LEDs and a mixing chamber. The LEDs are positioned to emit light into the mixing chamber. The mixing chamber includes an adapter having a wedge-shaped cavity with reflective walls. The cavity has an opening positioned to direct light into the light pipe. The mixing chamber includes scattering centers for redirecting light traveling in the cavity in directions that would not be obtained by reflection from the reflective walls.
