智能睡眠灯

<p><span>那里有很多智能照明系统，可以让您仅通过智能手机（甚至是语音）来改变灯光的颜色和变暗，但是这种称为</span><span>Lumos</span><span>的</span><span>开源</span><span>灯是一种有益于健康的智能照明系统。</span></p><p><span>Lumos</span><span>模仿太阳每天在头顶上方通过时的自然光，在早晨产生明亮的蓝色光，在晚上产生温暖的琥珀色光。</span></p><p/><div class="image-package"><img src="https://img.haomeiwen.com/i16057169/5ba9f4ebf3b84727.jpg" class="uploaded-img" style="min-height:200px;min-width:200px;" width="auto" height="auto"/>
