  • Phosphor-converted LED devices having improved light distribution uniformity
    Patent number: 7329907
    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.

  • Light-emitting diode module for flash and auto-focus application
    Patent number: 7284871
    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.

  • Method and apparatus for producing untainted white light using off-white emitting diodes
    Patent number: 7206507
    Abstract: A white light emitting device by using off-white light emitting diodes (LED's). Rather than using just pure white LEDs, the white light emitting device arranges those LEDs which exhibit off-white colors in a manner such that the combination of light emanating from these off-white LEDs produces a radiation which appears substantially pure white to the human eye.
