LED light source for scanner

It is disclosed an LED light source for use in a scanner, and in particular a series of lenses which are used to focus the LED-light on the front and back sides and drill to the LED light to the left and right sides , LED can compared to CCFL, when used as a light source, improve the problem of high power consumption, warm-up and the limitations of lifetime. Further expands the light through the lens the area of ​​the left and right sides on a scanned material. Therefore, the amount of the LED decreases, whereas it was known to use a large number of LEDs to achieve a softer light field, and achieves lower power consumption.
