    摘要： An optical pickup device including a lead frame and a board attached to the lead frame is provided. The lead frame includes optical components, such as a laser diode and an optical element, which are disposed within a lead frame. A photo diode is mounted on the board to receive a beam transmitted through the optical element. The board is adjusted with respect to the lead frame using the beam before attached to the lead frame. An upper opening and a lower opening are formed on an upper side and a lower side of the lead frame, respectively. An optical element installation space formed within the lead frame and defined by an upper side walls and an optical element support. A hole is formed in a central portion of the optical element support and communicates with the optical element installation space and a photo diode installation space which is defined by the optical element support and a lower side wall of lead frame. The laser diode emitting the beam is mounted on a laser diode support which is formed adjacent to the optical element support in the optical element installation space. The optical element mounted on the optical element support is disposed within the optical element installation space to direct the laser beam emitted from the laser diode toward an optical medium through upper opening and to transmit the laser beam to the photo diode of the board.

    摘要： An inner zoom lens system for use in a camera module having an image sensor and appropriate for an inner-focus type is provided. The inner zoom lens system includes, sequentially from an object side, a first lens group, a second lens group, a third lens group, and a fourth lens group. The first lens group is fixed and has minus refractive power. The second lens group has plus refractive power and performs a zooming operation by moving such that an interval between the first and the second lens groups is reduced when zooming from a wide angle end to a telephoto end. The third lens group has minus refractive power and moves such that a position of an image plane is corrected depending the zooming due to the movement of the second lens group. The fourth lens group has plus refractive power.

    摘要： An inner-focus type zoom lens system used for a camera module having an image sensor and using an LC lens is provided. The inner-focus type zoom lens system includes an objective lens group, a condensing lens group, at least one moving lens group, and an LC lens. The objective lens group is located most closely to an object side and fixed, and the condensing lens group is located most closely to an image side and fixed. The moving lens group is located between the objective lens group and the condensing lens group and moved for zooming. The LC lens includes an inner space filled with an LC material whose refractive index and abbe number change according to an applied voltage. The LC lens compensates for an image plane using the changes of the refractive index and the abbe number of the LC material when the zooming is performed by the moving of the moving lens.

    摘要： The present invention relates to a dipolar LED and a dipolar LED module incorporating the same, in which an upper hemisphere-shaped base houses an LED chip therein and adapted to radiate light from the LED chip to the outside, and a pair of reflecting surfaces placed at opposed top portions of the base in a configuration symmetric about an imaginary vertical plane. The vertical plane passes through the center of the LED chip perpendicularly to a light-emitting surface of the LED chip. The reflecting surfaces are extended upward away from the top portions of the base to reflect light from the LED chip away from the imaginary vertical plane. A pair of radiating surfaces are placed outside the reflecting surfaces, respectively, to radiate light from the reflecting surfaces to the outside. In this way, light emission from the LED chip can be concentrated in both lateral directions.
