  • Publication number: 20100283065
    Abstract: The invention relates to a light emitting diode device having a light extracting rough structure. The device includes a leadframe, one or more light emitting diode chips provided on and electrically connected to the leadframe, and a lens configured to encapsulate the one or more light emitting diode chips, the lens having a surface including a micro-roughness structure. The micro-roughness structure of the lens has a roughness between 0.1 ?m and 50 ?m. The invention also relates to a method of manufacturing a light emitting diode device having a light extracting rough structure.

  • Publication number: 20100264432
    Abstract: A light emitting device comprises two light-emitting diode (LED) groups, a group of luminophor layers, and an input terminal. The first LED group includes at least one blue LED emitting light having a dominant wavelength in a range between 400 nm and 480 nm, and the second LED group includes at least one red-orange LED emitting light having a dominant wavelength in a range between 610 nm and 630 nm. The group of luminophor layers, which are selected from one of silicates, nitrides, and nitrogen oxides, are positioned above the first LED group and partially converts the light emitted by the first LED group into light having a dominant wavelength in a range between 500 nm and 555 nm. The input terminal is connected to the two LED groups for providing desired electric energy thereto.
