如何利用蓝牙智能设计LED智能照明系统
蓝牙智能是最新的室内LED灯的无线控制流行的选择。随着蓝牙连接包括在每个智能手机和平板电脑，现成的界面为用户提供了简单的设置和控制灯。
使用智能手机使系统设计者有更多的选择，实现新功能的灯，如改变平衡的颜色或光的质量。
这种控制可以用的SimpleLink™cc2540t高温无线收发器和德克萨斯仪器加TPS76933电压调节器和tps62290 DC-DC变换器功率的灯实际LED控制器相结合的方法实现了。低功耗不是一个直接的问题，因为LED灯往往是从电源供电，但低功耗设计意味着较低的工作温度和更高的可靠性，使灯更长的寿命
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.
