Abstract: A lens includes a lens body having a bottom surface, a reflective surface, and a refractive surface. The bottom surface is to be disposed proximate to a light-emitting component. The reflective surface is disposed opposite to the bottom surface along a lens axis, and reflects a first portion of the light provided by the light-emitting component that is incident thereon toward the refractive surface. The refractive surface extends from an edge of the reflective surface to the bottom surface, and refracts a second portion of the light provided by the light-emitting component that is incident thereon as well as the first portion of the light reflected by the reflective surface theretoward in sideward directions relative to the light-emitting component. The lens body has cross-sections transverse to the lens axis, sizes of which increase gradually from a junction of the reflective surface and the refractive surface toward the bottom surface.

Abstract: A multi-resolution charge-coupled device (CCD) sensing device is provided. The multi-resolution CCD sensing device achieves the object of the invention by using more than two CCD shift registers. The purpose of the invention is to combine and store the charge signals from a longer CCD shift register to a shorter CCD shift register, and then to shift out the charge signals, so as to attain transmission functions with different resolutions. It can achieve the economy of smaller size and lower cost by using the multi-resolution CCD sensing device according to the invention, thereby increasing scanning speeds at lower resolutions.

Abstract: An image processing system integrates the scanning function with image processing function. The scanned image can be directly transmitted to a printer for high quality reproduction to serve a “scan to print” function. The system can also transmit the scanned image with or without being processed to a computer for further processing. The output from the computer can be transformed into image for rapid printout.

Abstract: The present invention provides a safe light emitting device that can avoid danger of explosion and fire whenever over current or over voltage occurs. The light emitting device includes a plurality of light emitting diode lamps in series. At least one of the light emitting diode lamps is a safe light emitting diode lamp. The safe light emitting diode lamp results in a broken circuit when either over current or over voltage in the light emitting device occurs. Through the incorporation of the safe light emitting diode lamp, the series light emitting device will automatically fail whenever over current or over voltage occurs and thus be prevented from explosion and fire.
