    Abstract: In an example, the present invention provides a gallium and nitrogen containing laser diode device. The device has a gallium and nitrogen containing substrate material comprising a surface region, which is configured on either a non-polar ({10-10}) crystal orientation or a semi-polar ({10-10} crystal orientation configured with an offcut at an angle toward or away from the [0001] direction). The device also has a GaN region formed overlying the surface region, an active region formed overlying the surface region, and a gettering region comprising a magnesium species overlying the surface region. The device has a p-type cladding region comprising an (InAl)GaN material doped with a plurality of magnesium species formed overlying the active region.

    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.

    Abstract: Accessories for LED lamp systems and methods of attaching accessories to illumination sources (e.g., LED lamps) are disclosed. A beam shaping accessories mechanically affixed to the LED lamp. The lens is designed to adapt to a first fixture that is mechanically attached to the lens. Accessories are designed to have a second fixture for mating to the first fixture such that the first fixture and the second fixture are configured to produce a retaining force between the first accessory and the lens. The retaining force is a mechanical force that is accomplished by mechanical mating of mechanical fixtures, or the retaining force is a magnetic force and is accomplished by magnetic fixtures configured to have attracting magnetic forces. In some embodiments, the accessory is treated to modulate an emanated light pattern (e.g., a rectangular, or square, or oval, or circular or diffused emanated light pattern). A USB connector is also provided.
