  • METHOD FOR ASSEMBLING CAMERA MODULE
    Publication number: 20120084976
    Abstract: The present invention discloses a method for assembling a camera module. The method includes putting plural conductive bumps on a conductive contact of a substrate such that a large conductive bump is formed, and pressing the substrate and an image chip together such that the conductive contact contacts with a pad formed on the image chip through the large conductive bump to combine the conductive contact and the pad. Since there is no contact between the substrate and the image chip but the large conductive bump, the method decreases the probability for fracture between the substrate and the image chip and improves the quality of the camera module.

  • LED control system using modulated signal
    Patent number: 8134299
    Abstract: An LED control system using a modulated signal includes a computer, a data storage unit, an AC power, a power conversion circuit, a control circuit, and an LED lamp string. The AC power is converted into a DC power by the power conversion circuit to supply a DC voltage to the control circuit and the LED lamp string. A computer control data is sent to the control circuit through the data storage unit by a user using the computer. The computer control data is modulated to a modulated signal by the control circuit. The modulated signal is sent to the LED lamp string with the same transmission line sending the DC voltage. The light of the LED lamp string is changed according to the modulated signal. The cost is reduced because the DC voltage and the modulated signal are sent in the same transmission line.
