Daylight-Sensitive Efficient Lighting

　　Daylight-Sensitive Efficient Lighting

　　在短短的十年中，发光二极管（LED）已成为电子设备的主要选择，使照明更节能。能够有效地产生强烈的光照水平使得LED在大多数应用中越来越受欢迎，超过了荧光和其他技术的能力。LED的另一个重要优势是它的可控性。

　　虽然调光的LED涉及一个更复杂的电路设计比简单的控制器，用于传统的白炽灯照明，LED支持的能力，不仅调整照明水平，但发射的颜色调整到一个良好的水平。这种可控性可以利用在各种应用中，从高湾照明仓库和工厂的智能温室。

　　LED lighting is already contributing to increased yield in agriculture by extending the possible growing season for a wide range of crops by several months in temperate climates. By improving yield and growing times， the technology makes rooftop agriculture more economic. As a result， cities can begin to contribute to global food production. An important aspect of smart greenhouse design is the ability to make the LEDs respond to ambient light levels to avoid overconsumption of electricity and to provide different colors to support the needs of crops over their lifecycle. The LEDs can be turned off completely during bright ambient lighting conditions， and be gradually brought online as it decreases.

　　In warehouses ambient lighting is less readily available， but it is often present through skylights and windows. The problem with traditional lighting design is providing consistent illumination over the entire floor space. Traditionally， luminaires will be set to provide a constant level of illumination that will be wasteful in areas of high ambient light levels. At the same time， areas in corners with few surrounding luminaires and windows or skylights may be comparatively dark. Smart LED lighting can compensate for these problems by adapting not only to changing natural light， but the impact of other luminaires.
