  • Patent number: 11172177
    Abstract: A projection system including at least a light source, at least a dichroic filter element and a light-adjusting diaphragm element is provided. The light source is configured to emit a first color light having a spectrum of a first wavelength range and a second color light having a spectrum of a second wavelength range. The dichroic filter element is configured to reflect or allow the first color light and the second color light to pass through. The light-adjusting diaphragm element has a filter and is located on an optical path generated after the first color light and the second color light are split. The first color light passes through the filter, which blocks at least a part of the energy of the second color light, such that a transmittance of the spectrum of the first wavelength range is greater than that of the spectrum of the second wavelength range.

  • Publication number: 20210226417
    Abstract: An ambient light rejecting screen used in a laser light source projector, which generates a light with a first wavelength and a light with a second wavelength, is provided. The screen includes a base, a light absorbing layer, a first filter layer and a second filter layer. The light absorbing layer is disposed on the base. The first filter layer is disposed on the light absorbing layer. The crystallization characteristic of the first filter layer corresponds to the light with the first wavelength and generates a reflective light with the first wavelength, and allows the light with remaining wavelengths to pass through. The second filter layer is disposed on the light absorbing layer. The crystallization characteristic of the second filter layer corresponds to the light with the second wavelength used to generate the reflective light with the second wavelength and allows the light with remaining wavelengths to pass through.

  • Publication number: 20150252494
    Abstract: The present invention provides a method for producing polyester fibers which improves the defects that polyester fibers and the textiles thereof cannot be easily dyed. In such method, fibers could be dyed by using dispersed dyes at ambient pressure and a temperature of 100° C. or less without adding carrying agents, and have good dyeability, high dyeing deepness and excellent color fastness. The textiles thereof have excellent dyeing retention. In the said method for producing fibers which could be easily dyed at low temperature, a composition consisting of 99.9 to 60% by weight of a first polyester component with a glass transition temperature (Tg) of greater than 20° C. to 100° C. and 0.1 to 40% by weight of a second polyester component with a glass transition temperature (Tg) of 20° C. to ?50° C. is melted and spun to such polyester fibers.
