Vitamin D deficiency has become a social problem in many countries as modern people’s indoor living time increases and their exposure to natural light shortens. In order to solve this problem, sun exposure is recommended. Outdoor activity guide service is provided by providing accurate UV-related information, while UV lighting technology is being developed in order to provide UV dose to indoor residents. However, these methods have limitations in directly supporting adequate UV doses for those who have difficulty in carrying out outdoor activities, whereas UV lighting does not provide accurate safety information about exposure. In this paper, a UVB-LED special lighting that supports indoor residents to meet a daily recommended UVB dose is proposed. First, the UVB-LED light source that can achieve an optimal UVB dose is selected. Its lighting characteristics are measured and analyzed and then a combination and control condition of the light source that can safely provide UVB dose are derived. After a stand-type lighting equipment considering ease of use is designed, a UVB-LED special lighting that meets the photobiological safety standard of lighting (Risk Group 2) is developed. The expected amount of vitamin D synthesis by distance and use duration is calculated through a performance test for the proposed lighting. The test results show that when the proposed lighting is used at a distance of 20 cm for 33–40 min, the daily recommended vitamin D synthesis can be achieved.

随着现代人室内居住时间的增加和自然光照射时间的缩短，维生素 D 缺乏症已成为许多国家的社会问题。为了解决这个问题，建议进行阳光照射。通过提供准确的紫外线相关信息来提供户外活动指导服务，同时正在开发紫外线照明技术以向室内居民提供紫外线剂量。然而，这些方法在直接为那些难以进行户外活动的人提供足够的紫外线剂量方面存在局限性，而紫外线照明不能提供有关暴露的准确安全信息。在本文中，提出了一种支持室内居民满足每日推荐 UVB 剂量的 UVB-LED 特殊照明。首先，选择能够达到最佳UVB剂量的UVB-LED光源。对其照明特性进行测量和分析，进而推导出能够安全提供UVB剂量的光源组合和控制条件。在设计了考虑易用性的立式照明设备后，开发了符合照明光生物安全标准（风险组2）的UVB-LED特殊照明。根据距离和使用时间的预期维生素 D 合成量是通过对拟议照明的性能测试计算得出的。测试结果表明，当建议的照明在 20 厘米的距离使用 33-40 分钟时，可以达到每日推荐的维生素 D 合成量。在设计了考虑易用性的立式照明设备后，开发了符合照明光生物安全标准（风险组2）的UVB-LED特殊照明。根据距离和使用时间的预期维生素 D 合成量是通过对拟议照明的性能测试计算得出的。测试结果表明，当建议的照明在 20 厘米的距离使用 33-40 分钟时，可以达到每日推荐的维生素 D 合成量。在设计了考虑易用性的立式照明设备后，开发了符合照明光生物安全标准（风险组2）的UVB-LED特殊照明。根据距离和使用时间的预期维生素 D 合成量是通过对拟议照明的性能测试计算得出的。测试结果表明，当建议的照明在 20 厘米的距离使用 33-40 分钟时，可以达到每日推荐的维生素 D 合成量。
