Patent number: 8721088Abstract: A lens array module includes a light incident surface, a light emitting surface opposite to the light incident surface, and a plurality of first and second lens surfaces. The first lens surfaces are arranged on the light incident surface to form into an array. The second lens surfaces are arranged on the light emitting surface to form into an array. The center of curvature of each of the first lens surfaces located at two opposite sides of a first reference point on the light incident surface deviates away from the first reference point in a direction parallel to a first reference axis, and the center of curvature of each of the second lens surfaces located at two opposite sides of a second reference point on the light emitting surface deviates toward the second reference point in a direction parallel to the first reference axis. A projection apparatus is also provided.Type: GrantFiled: May 29, 2011Date of Patent: May 13, 2014Assignee: Young Optics Inc.Inventors: Yi-Hao Kang, Jiunn-Lih Lin, Chia-Chang Lee, Chi-Tang Hsieh

Patent number: 7850315Abstract: A light integration rod having a light input end and a light output end opposite to each other is provided. The light integration rod includes a first reflective plate, a second reflective plate, a third reflective plate and a fourth reflective plate. The second reflective plate is opposite to the first reflective plate. The third reflective plate and the fourth reflective plate connect the first reflective plate and the second reflective plate, and are disposed opposite to each other. A long side of the first reflective plate is not equal to a long side of the second reflective plate. A short side at the light output end of at least one of the first reflective plate and the second reflective plate is separate from a short side of the third reflective plate and a short side of the fourth reflective plate at the light output end.Type: GrantFiled: October 17, 2007Date of Patent: December 14, 2010Assignee: Young Optics Inc.Inventors: Jiunn-Lih Lin, Huang-Ming Chen, Pei-Ching Liu, Tzu-Kai Wang, Chih-Hsien Tsai

Patent number: 6967795Abstract: The present invention provides a color wheel including a motor and a color filter module. The color filter module includes a first color filter having a first transmittance and a second color filter having a second transmittance that is smaller than the first transmittance. 50% of the first transmittance is corresponding to a first light wavelength and a second light wavelength that is larger than the first light wavelength. The second color filter and the first color filter have substantially same hues. 50% of the second transmittance is corresponding to a third light wavelength and a fourth light wavelength that is larger than the third light wavelength. The second color filter satisfies a first condition chosen from the third light wavelength being larger than the first light wavelength or the second light wavelength being larger than the fourth light wavelength.Type: GrantFiled: April 29, 2005Date of Patent: November 22, 2005Assignee: Young Optics Inc.Inventors: Chu-Ming Cheng, Jiunn-Lih Lin, Huang-Ming Chen
