In order to use REAX in ZEMAX, in the aspheric surface that REAZ operation set obtains different relative aperture, data point position conforms to data above, satisfactory aspherical equation is obtained by optimizing, must to transfer relative aperture to high by high for the bore of data point in EXCEL, here is that air flat board is placed in parallel light path (see figure 1), then the curve negotiating above-mentioned shape value point (see figure 3) making aspherical equation corresponding by operation set (see figure 2) on the dull and stereotyped rear surface of air, see and after optimizing in " solving aspherical equation (initial state) ZMX ", to obtain mirror non-spherical structure after LED condenser, thick at ZEMAX Zhong Ling center is variable, controlling limit thick is 0.2 just can obtain rear mirror structure, after after carrying out, mirror surface-shaped has designed, front mirror and rear mirror interval are generally decided to be 0.2, then optimize together with rear mirror, control the outgoing beam depth of parallelism, and light beam invests the front surface size of compound eye, and before last, mirror size also determines thereupon,
D (), when all optical elements design, note the restriction of mobile phone height 10mm, in other words: all aperture of lens should not be greater than 10mm;
E () in the ordinary course of things, containing aspheric lens, when for throwing light on, because working temperature is higher, should not adopt plastic lens, and low-melting glass will be adopted by hot-forming making.
The said control outgoing beam depth of parallelism is restricted at the inclination angle of each emergent ray to be less than 10 degree.
As can be seen from the technical scheme of the method for designing of the micro-optical projection system LED condenser of the present invention, because method for designing of the present invention is by parameters such as Control Radius, thickness, aspheric surface parameter, front mirror and rear mirror interval, the outgoing beam depth of parallelisms, in computer program, be optimized design, fully achieve the present invention and can ensure the goal of the invention that the light after optically focused is substantially parallel.
