摘要：
An illuminate device with an optical lens includes an aspherical lens and a LED. The aspherical lens, which has a flat end and an aspheric convex end, is held at the distance between 13.5 to 16.3 mm from the light center of the LED to the vertex of the aspheric surface of the lens. Light emitted from the LED enters the flat end of the lens and is refracted by the aspheric end of the lens to create a zoomable spot. An axial cross-section curve of the aspherical lens contents with a set of rectangular coordinates, which are (12,8.00), (11,8.05), (10,8.20), (9,8.44), (8,8.79), (7,9.25), (6,9.82), (5,10.51), (4,11.33), (3,12.29), (2,13.42), (1,14.75), (0,16.30), (−1,14.75), (−2,13.42), (−3,12.29), (−4,11.33), (−5,10.51), (−6,9.82), (−7,9.25), (−8,8.79), (−9,8.44), (−10,8.20), (−11,8.05), (−12,8.00).
