Abstract:

According to the characteristic of LED light source, here presented a compact projection of LOGO lamp based on 3.5×3.5 mm Lambert emission LED light source. Using Code V designed a two-slice imaging system, the object distance is 2900 mm, the image distance is 15 mm, and the image height is 5.7926 mm. According to the reversibility of optical path, To match a light source with small angle and high uniformity for the imaging system, a two-slice collimate system was designed in LightTools. The angle of light is 4.2°after the collimation, and the uniformity reached 91.7%. At last, put the two subsystems into LightTools, the results with a complete and clear uniform-pattern, the diameter of the pattern is 1600mm on the receiving plane, which was 2900 mm away from the entire system. Compared with the current systems, it has the advantages of shorter length, more simple structure and high uniformity.
