  • Publication number: 20070034887
    Abstract: A New Phosphor-converted LED Device (“NPCLD”) is disclosed. The NPCLD may include a lens over a phosphor body, in which the lens and the phosphor body each have a substantially convex upper surface. The NPCLD may alternatively include first and second lenses, the first lens having a substantially flat interface with a phosphor body.

  • Publication number: 20070030675
    Abstract: A flash module has a first light-emitting diode (“LED”) optically coupled to a first lens having a first viewing angle, and a second LED optically coupled to a second lens having a second viewing angle. The second viewing angle is greater than the first viewing angle. A first control signal line coupled to the first LED allows selectively activating the first LED. A second control signal line coupled to the second LED activates the second LED.

  • Publication number: 20060086946
    Abstract: In one embodiment, light emitted by a plurality of solid-state light emitters is mixed by mounting the plurality of solid-state light emitters on a transparent to translucent substrate so that they primarily emit light away from the substrate. The light emitters are then covered with a transparent to translucent encapsulant; and the encapsulant is coated with a reflective material that reflects light emitted by the light emitters toward the substrate. Related apparatus is also disclosed.

  • Publication number: 20050179376
    Abstract: A light emitting diode display device includes a substrate having a first conductive portion and a second conductive portion. A light emitting diode die is coupled to the first conductive portion. A wire bond is coupled to the light emitting diode die and coupled to the second conductive portion. An encapsulant encases the light emitting diode die and the wire bond above the substrate. An overlay is above the encapsulant, wherein the overlay has a high glass transition temperature.
