摘要: A motor stator includes an insulating frame having a plurality of projecting rods, an induction unit, and a plurality of conductive members. The induction unit includes an induction circuit board, a plurality of induction coils embedded within the induction circuit board, and a plurality of coil windings wound respectively on the projecting rods. The conductive members extend through the insulating frame and the induction circuit board for establishing an electrical connection between each of the induction coils and a corresponding one of the coil windings. The turn numbers of the coil windings are not limited by the area and thickness of the induction circuit board, and can be increased. Alternatively, the coil windings may be positioned to increase the magnetic pole slot number when energized. As such, a driving force of the motor stator can be increased.

摘要: Two or more molded ellipsoid lenses are formed on a packaged LED die by injecting a glue material into a mold over the LED die and curing the glue material. After curing, the refractive index of the lens in contact with the LED die is greater than the refractive index of the lens not directly contacting the LED die. At least one phosphor material is incorporated into the glue material for at least one of the lenses not directly contacting the LED die. The lens directly contacting the LED die may also include one or more phosphor material. A high refractive index coating may be applied between the LED die and the lens.

摘要: A method of light-emitting diode (LED) packaging includes coupling a number of LED dies to corresponding bonding pads on a sub-mount. A mold apparatus having concave recesses housing LED dies is placed over the sub-mount. The sub-mount, the LED dies, and the mold apparatus are heated in a thermal reflow process to bond the LED dies to the bonding pads. Each recess substantially restricts shifting of the LED die with respect to the bonding pad during the heating.

摘要: The present disclosure involves a method of fabricating a light-emitting diode (LED) wafer. The method first determines a target surface morphology for the LED wafer. The target surface morphology yields a maximum light output for LEDs on the LED wafer. The LED wafer is etched to form a roughened wafer surface. Thereafter, using a laser scanning microscope, the method investigates an actual surface morphology of the LED wafer. Afterwards, if the actual surface morphology differs from the target surface morphology beyond an acceptable limit, the method repeats the etching step one or more times. The etching is repeated by adjusting one or more etching parameters.
