    摘要: A compact auto focus lens module with a piezoelectric actuator revealed includes a piezoelectric actuator, an elastic element, at least two guiding fixtures, and a lens barrel with an optical lens set therein. By elastic force of the elastic element, a friction is generated between the lens barrel and the piezoelectric actuator. While being applied with a voltage, the lens barrel driven by the movement of the piezoelectric actuator moves along the optical axis under the guidance of the guiding fixtures. Due to fewer elements, compact volume, and light weight, the design is applied to miniature auto focus lens modules so as to achieve effects of fast movement, stable focusing and reduced tilting.

    摘要: A LED array flash for cameras includes a LED array and a controller. The LED array consists of at least one LED light source with first order lens. The LED light source may be further covered with a second order lens. Thus an oblong or round distribution pattern with uniform light intensity is emitted. The controller is used to control flash modes such as low brightness continuous lighting or high brightness pulse lighting with lighting time control so as to save power and avoid overheating.

    摘要: An auto focus lens module with a piezoelectric actuator having a piezoelectric actuator, a tangent thrust element, a sliding fixture, a metal member, a guiding fixture, and a lens barrel is revealed. By a thrust in the tangent direction generated from the tangent thrust element toward the outer edge of the lens barrel, a friction is generated between the lens barrel and the piezoelectric actuator. When the piezoelectric actuator is applied with a voltage, the lens barrel driven by the piezoelectric actuator moves along an optical axis for focusing with the auxiliary of the guiding fixture. Due to fewer elements, light weight and compact volume, the design is applied to miniature auto focus lens modules so as to achieve effects of fast movement, stable focusing and reduced tilting.

    摘要: An apparatus for driving a lens by electromagnetic driving force includes a frame, a barrel, a lens holder, a lens, a kicker, electromagnets and a resilient element. The barrel rotably mounted in the frame includes a first linkage structure. The lens holder includes a second linkage structure and is mounted on the barrel through the first and second linkage structures. The lens is coupled into the lens holder, and the kicker is mounted on an external wall of the barrel, and the electromagnets are mounted at the frame and the kicker respectively. The resilient element is connected to the barrel and the frame. The barrel can be pushed by a repulsion or attraction of a magnetic field produced by electrically conducting the electromagnets, and the first and second linking structures drive the lens holder to move from a first position to a second position.

    摘要: A glide head with mounted PZT sensor is used to obtain a glide avalanche curve. The glide head is subsequently gradually decreased until the signal is extremely high. First, at least one resonance frequency of the glide head is determined. The frequency component of the PZT glide signal to each specific irregular peak is analyzed by using the speed of the glide head divided by the bump spacing, multiplied by a factor, m, where m is an integer number. The next step of the present invention is to determine a glide avalanche break point of the recording medium. Then, the glide avalanche point is determined in the region which is between the irregular peaks and the extremely high signal.
