    摘要: A gallium nitride (GaN) device that has greatly superior current handling ability per unit area than previously described GaN devices. The improvement is due to improved layout topology. The layout scheme, which uses island electrodes rather than finger electrodes, is shown to increase the active area density over that of conventional interdigitated structures. Ultra low on resistance transistors can be built using the island topology. Specifically, the present invention, which uses conventional GaN lateral technology and electrode spacing, provides a means to enhance cost/effective performance of all lateral GaN structures.

    摘要: An illumination module includes a longitudinal support member including a base portion and a pair of sidewalls extending from the base portion that together define a channel that extends in a longitudinal direction. A printed circuit board (PCB) on the base portion extends in the longitudinal direction within the channel. A plurality of light emitting diodes (LEDs) are on the PCB in a linear array. A reflective sheet is within and extends across the channel, and includes a plurality of holes that correspond with locations of the LEDs on the PCB, and the LEDs are positioned in the holes. An optical film extends across the channel above the reflective sheet and defines an optical cavity between the reflective sheet and the optical film. The optical film, the reflective sheet and the sidewalls of the support member recycle light in the optical cavity.

    摘要: An illumination module includes a longitudinal support member including a base portion and a pair of sidewalls extending from the base portion that together define a channel that extends in a longitudinal direction. A printed circuit board (PCB) on the base portion extends in the longitudinal direction within the channel. A plurality of light emitting diodes (LEDs) are on the PCB in a linear array. A reflective sheet is within and extends across the channel, and includes a plurality of holes that correspond with locations of the LEDs on the PCB, and the LEDs are at least partially within the holes. An optical film extends across the channel above the reflective sheet and defines an optical cavity between the reflective sheet and the optical film. The optical film, the reflective sheet and the sidewalls of the support member are configured to recycle light in the optical cavity by reflecting some light emitted by the LEDs back into the optical cavity and transmitting some light emitted by the LEDs out of the optical cavity.
