  • Patent number: 8896235
    Abstract: An LED lighting system powered by an AC power source comprising a rectifier module configured to provide a rectified output to a first group of LED devices and a second group of LED devices electrically coupled to the first group of LED devices. A current monitor module electrically coupled to the first group and to the second group of LED devices is configured to determine a first current level using a drawn current level signal associated with the first group of LED devices and a second current level using a reference current level signal associated with the second group of LED devices. The current monitor module is electrically coupled to a temperature sensing module that is configured to generate at least one compensation factor based at least in part on a temperature. The compensation factor is used to control (directly or indirectly) current through the LED devices.

  • Patent number: 8846423
    Abstract: A device is provided with at least one light emitting device (LED) die mounted on a submount with an optical element subsequently thermally bonded to the LED die. The LED die is electrically coupled to the submount through contact bumps that have a higher temperature melting point than is used to thermally bond the optical element to the LED die. In one implementation, a single optical element is bonded to a plurality of LED dice that are mounted to the submount and the submount and the optical element have approximately the same coefficients of thermal expansion. Alternatively, a number of optical elements may be used. The optical element or LED die may be covered with a coating of wavelength converting material. In one implementation, the device is tested to determine the wavelengths produced and additional layers of the wavelength converting material are added until the desired wavelengths are produced.

  • Patent number: 8628985
    Abstract: Light emitting devices with improved light extraction efficiency are provided. The light emitting devices have a stack of layers including semiconductor layers comprising an active region. The stack is bonded to a transparent lens having a refractive index for light emitted by the active region preferably greater than about 1.5, more preferably greater than about 1.8. A method of bonding a transparent lens to a light emitting device having a stack of layers including semiconductor layers comprising an active region includes elevating a temperature of the lens and the stack and applying a pressure to press the lens and the stack together. Bonding a high refractive index lens to a light emitting device improves the light extraction efficiency of the light emitting device by reducing loss due to total internal reflection. Advantageously, this improvement can be achieved without the use of an encapsulant.
