Abstract: The present invention provides a light source module. The light source module includes a circuit board, a metal base, a plurality of LEDs, a plurality of bonding wires and a reflective layer. The metal base is arranged on the circuit board and has a bottom wall and a peripheral wall upwardly extending from the bottom wall. The bottom wall and the peripheral wall cooperatively define a recess. The bottom wall has a through groove exposing the circuit board. The LEDs are arranged on the bottom wall. The bonding wires electrically connect the LEDs to the circuit board through the through groove. The reflective layer is arranged in the through groove and seals the through groove. Therefore, the light source module has better heat dissipation effect and the overall illumination intensity of the light source module is increased.

Abstract: A controlling method and a transmission device are provided for improving the using distance and performance of a RFID system. The transmission device and the controlling method therefore are provided between the reader and the tag so that the strength and the using range of the RFID system are improved. Furthermore, optional and customized functions can easily be modified with the RFID system. Therefore, the RFID system of the present invention can be used in a wider range of applications.
