Abstract: A light emitting diode (LED) lamp tube includes a tubular enclosure extending along an axial direction and having an inner peripheral surface. A lamp device is disposed in the enclosure, and includes a circuit board, and a plurality of LEDs electrically connected to the circuit board. Two connectors are disposed respectively at two ends of the enclosure and are electrically connected to the circuit board. The connectors are adapted to be electrically connected to a power source. An optical film unit is disposed on the inner peripheral surface of the enclosure. The optical film unit has a film body and a plurality of protrusions arranged along the axial direction and protruding from the film body toward the inner peripheral surface of the enclosure.

Abstract: A system and method for calibrating an integrated circuit. The method includes configuring a first impedance for a first output of the integrated circuit according to a first configuration code and measuring a first voltage at the first output which corresponds to the first configuration code. The method further includes configuring a second impedance for a second output of the integrated circuit according to a second configuration code and measuring a second voltage at the second output which corresponds to the second configuration code. A determination of which of the first voltage and the second voltage is nearest to a predetermined voltage value. Based on the voltage determination, the integrated circuit is configured according a code of said first and second codes that corresponds to the voltage nearest to the predetermined voltage.
