Hei-Tong Ching has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7205719
    Abstract: A light source with LED and optical protrusions is provided. It comprises an optical panel and at least one optical plate. The light source can be used together with a heat sink or an optical element to enhance its performance. The optical panel forms an optical surface having plural optical protrusions to reflect and mix lights emitted from the LEDs. The optical plate is inserted into at least one slot on the optical panel, and it comprises a heat dissipation core plate and at least one electric circuit layer. The electric circuit layer comprises LEDs and at least one control circuitry. The electric circuit layer can be attached to either single side or both sides of the heat dissipation core plate. The invention achieves good uniformity and high intensity of the combined lights with desired chromaticity.

  • Publication number: 20050140980
    Abstract: An optical measurement apparatus is provided with a light source and guiding module and a receiving module in the present invention. The light source and guiding module, composed of a light source module and a light-guiding apparatus, is used to provide a low-cost area light source and to transfer the area light source to become a linear incident light through the light-guiding apparatus. And the receiving module, composed of a linear or area CCD sensor, is used to provide the linear or area detection for an array-type sample with the help of the light source and guiding apparatus. The present invention will simplify the complexity of the optical mechanism of two-dimension moving and single-point-scanning mode of the conventional optical measurement apparatus.
