Patent number: 11982633Abstract: The present disclosure provides a method for analyzing the signal of a neutral atom imaging unit, including: preparing a neutral atom imaging unit, which includes a semiconductor detector array and modulation grids disposed at intervals in front of the semiconductor detector array; preparing a neutral atom source plane, energetic neutral atoms emitted by the neutral atom source plane are received by the semiconductor detector array after passing through the modulation grids, and the modulation grids form a projection on the semiconductor detector array; obtaining a response function of the imaging unit according to the projection; calculating the data signal obtained by the neutral atom imaging unit; and performing inversion imaging on the neutral atom emission source according to the response function of the imaging unit and the data signal. The method well inverts the neutral atom emission source to obtain the intensity and size of the neutral atom emission source.Type: GrantFiled: November 9, 2020Date of Patent: May 14, 2024Assignee: Peking UniversityInventors: Yongfu Wang, Qiugang Zong, Linghua Wang, Hongfei Chen, Hong Zou, Xiangqian Yu, Weihong Shi, Lyu Zhou

Patent number: 11959609Abstract: A lens unit, a lens for a low-beam illumination module, a low-beam illumination module and a vehicle. The lens unit includes a rear surface and a front surface; the lens unit has a focal line, and the focal line is a straight line perpendicular to a light emitting direction of the lens unit; the rear surface and the front surface are adapted to project light rays passing through the focal line into parallel light rays, and the front surface is a free-form curved surface. The lens unit has the optical characteristics of a cylindrical lens, and is able to cause parallel incident light to be focused into a line instead of a focal point upon passing through the lens unit.Type: GrantFiled: June 16, 2021Date of Patent: April 16, 2024Assignee: HASCO VISION TECHNOLOGY CO., LTD.Inventors: Xiangqian Chen, Zhaoyu Chen, Guomin Xu, Tao Zhang, Ying Li, He Zhu, Wenhui Sang

Patent number: 11920755Abstract: An automotive headlamp system and an automotive lamp. The automotive headlamp system comprises a light source, a primary optical element, an automotive signal lamp structure, and a secondary optical element arranged sequentially along the light emitting direction. The automotive signal lamp structure comprises a light-transmitting portion and a rotating shaft. The light-transmitting portion comprises at least one light-transmitting plate mounted on the rotating shaft which can be driven to rotate by the rotating shaft. By means of rotation, light from the light source exits from the primary optical element, then selectively passes through one of or none of the light-transmitting plates, and is then projected by means of the secondary optical element to achieve a corresponding signal lamp function. The light-transmitting plate mounted on the rotating shaft is used to replace an existing signal lamp, reducing the space occupied by the original signal lamp, decreasing the volume of a headlamp.Type: GrantFiled: August 31, 2021Date of Patent: March 5, 2024Assignee: HASCO VISION TECHNOLOGY CO., LTD.Inventors: Meng Li, Zhaoyu Chen, Ying Li, Xiangqian Chen, He Zhu, Wenhui Sang

Patent number: 11898714Abstract: A vehicle lamp optical assembly includes a primary optical unit having a plurality of primary optical units arranged side by side. The primary optical unit has a light entrance portion and a light guide portion. The light guide portion has a light entrance portion mounting surface and a primary light emission surface. The light entrance portion mounting surface has at least one light entrance portion. The light entrance portion is configured to enable incident light to be converged and emitted to the light guide portion, and the light guide portion is configured to guide the incident light to be emitted from the primary light emission surface; and a secondary optical unit. The secondary optical unit has a secondary light emission surface and a secondary light entrance surface corresponding to the primary light emission surface. The secondary light emission surface is a narrow and long smooth curved surface.Type: GrantFiled: March 26, 2021Date of Patent: February 13, 2024Assignee: HASCO VISION TECHNOLOGY CO., LTD.Inventors: Meng Li, Xiangqian Chen, Zhaoyu Chen, Ying Li
