Abstract: An apparatus is adapted for controlling a lamp unit mounted on an automobile body, and includes a housing for housing input and output rods, and a transmission gear. The transmission gear meshes with a worm segment of the input rod such that the transmission gear is driven by the worm segment to rotate in response to rotation of the input rod. The output rod has a coupling end portion coupled to the lamp unit, and a rack segment meshing with the transmission gear such that the output rod is movable relative to the housing in response to rotation of the transmission gear, thereby driving movement of the lamp unit relative to the automobile body.

Abstract: A vehicle headlight apparatus includes a lamp device having an optical axis and generating light beams. A lens device has a plurality of lenses disposed in front of the lamp device. A reflector unit has a plurality of reflecting surfaces. Any two adjacent ones of the reflecting surfaces are spaced apart from each other along a transverse direction perpendicular to the optical axis. The reflecting surfaces reflect the light beams generated by the lamp device, and face respectively the lenses. The light beams reflected from each of the reflecting surfaces intersect at a focal point of a corresponding one of the lenses, and are subsequently transmitted into the lenses so that the light beams are parallel after they pass through the corresponding one of the lenses.

Abstract: An illumination device includes a circuit board unit having positioning hole units corresponding respectively to LEDs mounted thereon. Each positioning hole unit includes a first positioning hole, and a second positioning hole having a diameter larger than that of the first positioning hole. A lamp seat has positioning post units corresponding respectively to the positioning hole units in the circuit board unit. Each positioning post unit includes a first positioning post, and a second positioning post having a width larger than that of the first positioning post. When the circuit board unit is mounted on the lamp seat, the first and second positioning posts of each positioning post unit respectively extend through and engage the first and second positioning holes of a corresponding positioning hole unit in the circuit board unit, thereby positioning the circuit board unit to the lamp seat.
