Abstract

An optical mouse system with an illumination guide having a concave lens for spreading light to create a uniform, low contrast, illumination pattern is disclosed. The uniform illumination pattern increases the accuracy of mouse movement detected by the sensor. The illumination source and optical sensor are mounted in the same plane, directly on the PCB. The higher angle of the optical path causes more light to be reflected to the optical sensor, increasing optical efficiency and allowing a smaller, lower powered LED to be used. This also results in increased sensitivity of the optical sensor. Lower power usage increases battery life for mobile or wireless-mouse use, while reducing thermal waste considerations. This allows the creation of a significantly smaller form factor for the overall package, thereby reducing materials costs and giving designers more flexibility for external design considerations.
