Abstract: This invention provides an air disinfecting device for disinfecting or decontaminate air, which comprises a first metal plate and a second metal plate opposite to the first metal plate, a UVC LED mounted on the first metal plate, and a power supply providing power to the UVC LED. The second metal plate has an area large enough such that lights emitted from the UVC LED will be enclosed inside the air disinfection device.

Abstract: An optical system includes a collimated light source, a beam splitter, two mirrors and two lenses, a focus lens, and a detector. An initial light beam is generated by the light source and then separated by the beam splitter into a first light beam and a second light beam. The two mirrors respectively direct the first and second light beams on a sample with symmetrical paths and the two lenses focus the first and second light beam on the sample respectively. The first and second light beams are reflected from the sample and along the counterpart paths to the beam splitter. An interfered light beam is then generated by combining the reflected first and second light beams, and focused by a focus lens on a detector. A Dove prism can be configured between one mirror and one lens of the two for contrast enhancement. It can produce the photon combination with same of direction in this setup to enhance contrast.

Abstract: By using chip-by-chip, mainly separation technology, micro LED can be made very accurately and efficiently. First, after epitaxial process, the LED epi-wafer is processed into micro LEDs. Second, bonding substrates with driving circuits are provided for the LED epi-wafer. Then, each LED chip is fastened to the substrate chip-by-chip simultaneously or sequentially, and each LED chip may be transferred by using separation technology simultaneously or sequentially. The LED epi-wafer per se can be also provided as LED display substrate.
