  • Patent number: 8382335
    Abstract: A light emitting diode module is produced using at least one LED and at least two selectable components that form a light mixing chamber. First and second selectable components have first and second types of wavelength converting materials with different wavelength converting characteristics. The first and second wavelength converting characteristics alter the spectral power distribution of the light produced by the LED to produce light with a color point that is a predetermined tolerance from a predetermined color point. Moreover, a set of LED modules may be produced such that each LED module has the same color point within a predetermined tolerance. The LED module may be produced by pre-measuring the wavelength converting characteristics of the different components selecting components with wavelength converting characteristics that convert the spectral power distribution of the LED to a color point that is a predetermined tolerance from a predetermined color point.

  • Patent number: 8333488
    Abstract: Embodiments of the present invention relate to a compact optical assembly which improves collimation of light produced by multiple LED light sources in a light engine. A shaped primary reflector located over the light engine reflects the light toward a larger shaped secondary reflector. The shapes of the reflectors are selected to cooperatively produce a highly collimated light beam. Color mixing may be improved by providing a plurality of facets on the reflective surfaces of at least one of the primary reflector or the secondary reflector.

  • Patent number: 8330342
    Abstract: This light emitting diode (LED) device provides a 360 degree lighting angle in the horizontal plane and a 300 degree lighting angle in the vertical plane while simultaneously addressing LED die thermal management, which is critical to high lumen output LEDs. This LED lighting device is comprised of the LED lens, the LED holder and the heat sink stem. Light produced by at least one LED die traveling vertically is diffused by the top refractive portion of the lens. Light rays directed towards the pointed elements are totally internally reflected downwards then refracted out of the lens, thus resulting in a spherical light pattern. This technology is designed as a replacement for conventional light sources, such as incandescent light bulbs, halogen bulbs, CFLs (compact fluorescent lamps) and metal halide lamps.

  • Patent number: 8328405
    Abstract: A light emitting apparatus includes multiple Light Emitting Diode (LED) device controller integrated circuits and multiple LEDs of same color, but of different electrical and/or optical characteristics. A respective LED is electrically connected to a respective LED device controller integrated circuit. The respective LED may also be mounted on the respective LED device controller integrated circuit. The LED device controller integrated circuits are configured to independently control a current and/or voltage that is provided to the LED that is electrically thereto, so as to compensate for the different electrical and/or optical characteristics of the LEDs of the same color.

  • Patent number: 8314555
    Abstract: A lamp including a two-sided source plate, a plurality of light sources, a lens, a diffuser plate, and a driver insulator is disclosed. One set of the light sources generates white light and is attached to one side of the source plate. Another set of the light sources generates colored light and is attached to the source plate's other side. The lens encapsulates the white light-generating set, and redirects that white light. The driver insulator and the diffuser plate are each in contact with the source plate's other side. The driver insulator, diffuser plate, and that side of the source plate define a light box region that contains the colored light-generating set of light sources. The driver insulator acts as a reflector, and the diffuser plate acts as a diffuser, such that colored light is dispersed from the light box region through the diffuser plate.
