  • Publication number: 20150155762
    Abstract: A semiconductor module includes a switching element, a molded body, and a motor terminal. The molded body having the switching element disposed therein. The motor terminal has a base portion and a connection portion having an insertion hole into which a motor wire is inserted and connected with the winding wire. The connection portion has a cutaway region that defines a slot. The winding wire of the motor and the semiconductor module are connected via the motor wire and the motor terminal, thereby reducing the number of components used for such connection compared with a connection that uses a connector, and achieving a volume reduction of the semiconductor module and a driver device using the same.

  • Publication number: 20130329397
    Abstract: A laser lighting module includes a base part, a laser diode which is a blue laser device, a substrate with which the laser diode is in contact, a ceramic phosphor which reflects light entering from the laser diode to thereby change a direction of the light and is excited by the light to generate yellow fluorescence, and a lens for adjusting luminous intensity distribution of light emitted from the ceramic phosphor. The substrate is formed of a material which is thin and has excellent thermal conductivity, and is in surface contact with the laser diode and the base part. In the laser lighting module, since the substrate serves as a device heat radiator, it is possible to easily remove the heat generated by the laser diode.
