微控制器在商業(yè)照明中的應(yīng)用

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

　　將網(wǎng)絡(luò)節(jié)點添加到照明系統(tǒng)允許照明系統(tǒng)從中心點控制，與企業(yè)軟件集成以開關(guān)電源。然而，微控制器的日益集成，特別是與脈沖寬度調(diào)制塊，允許他們直接控制照明系統(tǒng)，以提供更有效的控制和更低的成本。

　　降低商業(yè)設(shè)施的能源供應(yīng)成本是所有權(quán)要求的關(guān)鍵成本。隨著能源成本的上升，商業(yè)辦公環(huán)境的照明成本相當(dāng)可觀。當(dāng)房間里沒有人時，可以關(guān)掉照明，根據(jù)建筑物的占用情況自動開關(guān)，這給設(shè)備經(jīng)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.
