Abstract: An optical mouse includes a bottom casing, a top cover mounted to the bottom casing to define an interior space. A circuit board and a lens set are located in the interior space. The bottom casing has an opening. A detecting device is mounted to the circuit board. A receiving portion and a light emitting diode (LED) are mounted to a bottom side of the detecting device in alignment with a slot in the circuit board. A solder pad to which an electrical conductor is connected has a central bore and is positioned on a circumferential margin of a light projection surface of the LED to allow light projected from the light projection surface to transmit through the central bore. The lens set is located between the circuit board and the bottom casing, and includes a reflection member and a lens.

Abstract: An optic mouse includes a housing having a bottom casing and a top cover mounted to the bottom casing, a circuit board mounted in the housing and a splitter mounted on the bottom casing. The bottom casing defines an opening. A detecting device is mounted to the circuit board and has a receiving portion in alignment with the opening of the bottom casing. A laser source is arranged on one side of the detecting device. The splitter has top and bottom faces respectively opposing the receiving portion of the detecting device and the opening of the bottom casing and a side face opposite to the laser source. By this, a light beam from the laser source is made convergent and is prevented from divergence by making use of the polarity characteristics of the light from the laser source and the splitter. Excellent operability of the mouse can be realized.

Abstract: A wireless optic mouse includes a casing inside which an optic module, a wireless communication unit and a built-in power source are arranged. The power source powers the optic module and the wireless communication unit. The optic module includes an infrared light emitting diode capable to emit an infrared signal of wavelength between 800-1,000 nm and a sensor for receiving the infrared signal that is reflected by a desk surface. The sensor generates a signal in response to the infrared optic signal received and applies the signal to the wireless communication unit that transmits the signal to a host computer in a wireless manner. The operation of the optic module is based on the infrared light that requires low power consumption but provides a high precision. Thus the service life of the power source is extended. The wireless communication between the mouse and the host computer realizes excellent mobility of the mouse.

Abstract: A method for fabricating a LED has the steps of affixing the chip, wire bonding, isolation layer formation; and phosphor sedimentation. Before the isolation layer becomes solid, a phosphor is applied onto the outer face of the isolation layer and by means of the sedimentation effect, the phosphor is thus immersed in the isolation layer evenly so as to achieve the purpose of emit light evenly.
