如何利用藍牙智能設計LED智能照明系統(tǒng)

　　藍牙智能是最新的室內LED燈的無線控制流行的選擇。隨著藍牙連接包括在每個智能手機和平板電腦，現成的界面為用戶提供了簡單的設置和控制燈。

　　使用智能手機使系統(tǒng)設計者有更多的選擇，實現新功能的燈，如改變平衡的顏色或光的質量。

　　這種控制可以用的SimpleLink?cc2540t高溫無線收發(fā)器和德克薩斯儀器加TPS76933電壓調節(jié)器和tps62290 DC-DC變換器功率的燈實際LED控制器相結合的方法實現了。低功耗不是一個直接的問題，因為LED燈往往是從電源供電，但低功耗設計意味著較低的工作溫度和更高的可靠性，使燈更長的壽命

　　A USB-based demonstration system includes a fully tested design with firmware， GUI， demo and getting started guide， and a full bill-of-materials.

　　The heart of the design is the CC2540T， which is packaged in a compact 6 x 6 mm 40-pin quad flat pack. This is a cost-effective， low-power， true wireless MCU for Bluetooth low energy applications based around an 8051 microcontroller core. The device enables a robust BLE master or slave node to be built with a very low total bill-of-materials by integrating in-system programmable flash memory， 8 KB of RAM， and other powerful supporting features and peripherals. The CC2540T is suitable for systems where very low power consumption is required as very low-power sleep modes are available. A short transition time between operating modes further enables low power consumption.
