光学技术开辟农业增产新路径
优化后的光发射装置与传感器可协助农户更高效地管理资源，提升作物产量。
光学技术开辟农业增产新路径
农业正同时承受来自多方面的压力。农民不仅面临淡水、耕种与收割作物及照料牲畜的人力等关键资源短缺的困境，还需满足日益增长的粮食需求——预计全球人口将从当前的82亿增长至2037年的90亿。根据联合国预测，世界人口将在21世纪80年代中期达到103亿的峰值。
气候变化与人口压力曾引发数次“绿色革命”，通过优化肥料施用、深化机械化作业及遗传学突破培育新型种子，实现了单位面积产量提升与抗旱抗病性的增强。然而这些传统技术带来的显著增益已近极限，技术改良的边际效益持续递减，农业领域亟需在未来农场中引入新一代智能技术。
这些智能技术涵盖室内农场的补光系统、农产品无损检测的光学传感器，以及农用机器人的光学导航装置。全球领先的光电半导体企业艾迈斯欧司朗正致力于将核心技术应用于这个关乎人类生存的基础产业。
智能补光室内农场缓解用水压力
《水处理工程学报》2024年研究指出，全球约40亿人口正面临严重缺水困境。尽管全球变暖与城市化进程是重要诱因，但研究报告显示，农业消耗了80%~90%的淡水资源，而其水资源利用效率均值仅为45%。
节约用水的需求推动了室内农场和温室的蓬勃发展。这是由于这些设施能够构建闭环水循环系统：收集作物释放的水蒸气，将回收水再次用于灌溉种植。
为城市社区提供服务的室内农场通过种植沙拉蔬菜、番茄和草莓等易腐作物，将种植区域布局在靠近消费者和销售终端的位置，从而大幅缩短食物运输里程，有效降低了农业对气候的影响。
随着高效LED应用技术的改进——从最初使用白光LED，到现在越来越多采用能提供最优生长光效的蓝光与超红光发光器组合——室内种植正变得越来越具有经济吸引力。
艾迈斯欧司朗的LED产品因卓越品质和出众的电源转换效率（衡量电能直接转化为光能效率的指标）而备受青睐。在植物照明领域，LED品质对生产效率具有决定性影响：通过精准控制植物专属波长组合、光照强度及光束模式的照明设备，能让农户根据不同作物特性可靠调整光照方案，实现最低能耗下的最大产量。研究还表明，采用动态光谱优化的照明技术可大幅减少农作物农药使用量。
在温室中，LED照明系统还融合了光传感器技术。这些传感器不仅实时监测作物接收的自然光照强度，还能分析环境光的光谱特性。基于这些数据，农户可精准判断何时需要开启LED补光，为植物提供最佳光强与光色组合；而当环境光照充足时，则关闭或调弱人工照明，从而实现节能降本。
Transparency and Control with New Automotive Lighting Technology
Drawing on a decades-long heritage in automotive lighting, ams OSRAM has pioneered the development of technology which meets the new design-driven requirements for the car interior.
Its ALIYOS™ technology gives an impression of floating ‘light out of nowhere’: ultra-thin ALIYOS™ LED foils can be applied almost invisibly to any base material, including curved surfaces.
Design concepts enabled by the ALIYOS™ technology include light appearing from ‘behind’ wood paneling on a fascia, or from behind fabric, through the integration of an extremely low-profile assembly for the lighting functionality.
This technology may be combined with electronic touch sensors to enable illuminated buttons to be embedded into surfaces in the dashboard or elsewhere, creating a striking space-age effect, and allowing user-interface devices to be integrated more seamlessly into the materials and structure of the interior than conventional buttons or knobs can be.
The ALIYOS™ technology can also be used to create almost-transparent light panels capable of showing pixelated symbols, multi-segment symbols such as numbers, or other information implemented in customized light patterns. The transparency of ALIYOS™ LED-on-foil technology helps designers to intensify the sense of spaciousness inside the cabin, and to produce the desirable effect of airiness demanded by the new design philosophy.
This precise control makes it possible to not only create specific moods or harmonize with changing visual elements like center displays, but also to unlock dynamic lighting effects that add a whole new layer of experience.
These dynamic lighting effects are not just about aesthetics. Patterns like pulsating or sweeping light can fulfill clear functional purposes – such as warning the driver, drawing attention to controls, or reinforcing system feedback while also adding a sense of motion and emotional depth to the design.
The color-changing capability provided by RGBi LEDs such as the E3731i is supported by the AS1163 Stand-Alone Intelligent Driver (SAID) IC. Both devices are compatible with the Open System Protocol, or OSP, which provides an open, license-free method for connecting LEDs and other devices in a simple control network.
The configurable OSP system enables various network configurations – daisy chains and loopbacks – as well as parallel branching. The intelligence in the AS1163 SAID enables it to receive color-changing instructions from a host microcontroller and implement them in up to three RGBi LEDs, eliminating the need for several local microcontrollers in a dynamic cabin lighting system.
Car manufacturers can implement an LED array to create dynamic emotional effects with any OSP-compatible LEDs .
