Title: Innovations of Chong-Min Chang
Introduction
Chong-Min Chang is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of optical technology, holding a total of 5 patents. His work primarily focuses on light source modules and projecting devices, which have applications in various display systems.
Latest Patents
One of his latest patents is a light source module designed for collecting reflective beams from a light source. This module includes a light source, a light-selection device, and a reflective device. The light source generates an incident beam, while the light-selection device allows part of this beam to pass through and reflects the rest as a reflective beam. The reflective device then reflects this beam back to the light-selection device for further processing.
Another significant invention is a projecting device for displaying computer images. This device operates without prisms and consists of a light source that generates an incident light beam. It features a reflective image module with multiple separately controlled reflective surfaces to create an image-containing reflected light beam. The design includes a first lens set for concentrating the incident light beam and a reflective mirror that directs the light through the lens onto the image module. This innovative approach prevents interference of light beams, enhancing the quality of the projected image.
