微控制器在商業照明中的應用

　　微控制器是任何控制系統的核心，對于商業照明來說，它們在降低功耗方面扮演著兩個關鍵角色。

　　將網絡節點添加到照明系統允許照明系統從中心點控制，與企業軟件集成以開關電源。然而，微控制器的日益集成，特別是與脈沖寬度調制塊，允許他們直接控制照明系統，以提供更有效的控制和更低的成本。

　　降低商業設施的能源供應成本是所有權要求的關鍵成本。隨著能源成本的上升，商業辦公環境的照明成本相當可觀。當房間里沒有人時，可以關掉照明，根據建筑物的占用情況自動開關，這給設備經理提供了更大的空間來降低運營成本。

　　This is part of a move to “daylight harvesting”， where natural light is combined with the artificial lighting system to make the environment as effective as possible to work in and also to reduce costs. This needs a more complex design， with different types of lighting systems in different places to produce different types of light. For example， halogen spot lights in darker areas away from natural light from windows gain functionality to be switched on later in the day rather than using more diffuse fluorescent lighting that is constantly on.

　　All of these systems should also be connected to a central control to optimize the use of the lighting throughout the day and into the evening. These control systems need to be as simple to use as possible， ideally with intelligence built into the network node to reduce the overall complexity for the user.
