摘要： A laser scanning unit mainly includes a semiconductor laser, a collimator, a micro electronic mechanic system (MEMS) oscillatory mirror, and an fθ lens or an f sin θ lens. The MEMS oscillatory mirror is disposed between the collimator and the fθ lens to replace a conventional rotary polygonal mirror for controlling a direction in which laser beams are projected from the oscillatory mirror to the fθ lens. With the MEMS oscillatory mirror, the cylindrical lens may be omitted from the laser scanning unit and noises produced by the polygonal mirror rotating at high speed may be avoided. Moreover, the MEMS oscillatory mirror allows bi-directional scanning to therefore enable increased scanning frequency, simplified structure, and improved scanning efficiency.

摘要： An in-line laser scanning unit (LSU) with multiple light beams is disclosed. The LSU includes a minimized in-line mirror set composed by a plurality of vertically stacked Micro Electronic Mechanical System (MEMS) oscillatory mirrors and a linear corresponding scanning lens set formed by a plurality of F-Sin θ lens stacked vertically so as to correct the variation of reflective angle of the oscillatory mirror that is sinusoidal in time. Thus the scanning speed of multiple laser beams on the image plane is constant. Therefore, the volume of color printers is effectively reduced and the scanning efficiency is improved when the LSU in accordance with the present invention is applied to the optical engines of color printers.

摘要： A LED optical lens and an illumination device thereof are revealed. The optical lens includes a light-source side surface and an image side surface of the LED optical lens that both are designed respectively according to mathematical expressions of freeform surfaces such as Anamorphic formula and Toric formula Thus the optical lens has different curvatures along different axes. After light from LED emitting into the optical lens at a fixed incident angle, emergent light with different divergence angles along different axes is generated. For example, the divergence angle along the long axis is larger than that along the short axis. Therefore a uniform and near rectangular distribution pattern is formed on the target area Moreover, a plurality of optical lenses aligned along the same axes is arranged at a holder to form a lens array. The lens array is used together with a LED array so as to form a LED illumination device.
