Lighting
介紹
控制一盞燈的最簡單的方式是打開或關閉它,使用the Generic OnOff state;
較之高級一點的是,控制燈的亮度,使用the Light Lightness Actual state;
如果是可控制其色溫(Colour Temperature)的燈,使用the Light CTL state;
比如 Incandescent light (白熾燈)色溫爲2700K到3000K,fluorescent light(熒光燈)的色溫爲5000K
如果是可變顏色的燈,可以使用三種狀態分別去控制它的三維(Hue 色相,Saturation 飽和度,Lightness 亮度,即HSL):the Light HSL Hue state、the Light HSL Saturation、the Light Lightness Actual state。

The HSL model [4] is considered to be the default model for controlling color light in a mesh network.
The HSL color space can be converted to other color spaces. For example, the following code may be used when converting HSL to RGB
In a mesh network, the color light control model for professional applications is the xyL model。xyL的含義詳見藍牙mesh spec。
