| 中文摘要: |
| 利用Zemax光学设计软件设计了一款适用于家用小型汽车前照远光灯的汽车反光杯。针对国标GB 7258-2017《机动车运行安全技术条件》性能要求，对普通的汽车反光杯采取结构改良等优化措施，使其二次配光效果更好，中央光斑进一步集中，视觉效果更加柔和。仿真结果表明：系统有效作用距离为150 m，10 m处中央光斑平均光照强度为4 552 lx，出光角为-10°～+10°。各项主要性能指标均达到国家最新标准，在不增加工业生产成本的前提下，具有适应未来批量3D打印生产模式的潜力。 |
| 英文摘要: |
| Using the Zemax optical design software, a car reflector for small car headlights is designed. Aiming at the performance requirement of GB 7258-2017 Safety Technical Conditions for Motor Vehicle Operation, the optimization measures such as structural improvement are adopted for ordinary automobile reflectors to make the secondary light distribution effect more excellent, make the central spot more concentrated, and make the visual effect softer. Simulation results have shown that the effective working distance of the system is 150 m. The average light intensity of the central spot at 10 m is 4 552 lx, and the exit angle is from -10° to +10°. The main performance indicators have reached the latest national standards, and have the potential to adapt to the future 3D printing mass production mode without increasing the industrial production cost. |
