text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">本设计是一个基于N32G430C8L7设计的智能台灯。功能有1、台灯的开关,，2、灯光亮度的调节。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">调节亮度的部分采用了电流反馈的方式,让调光更加有层次感.本设计有电压采集电路,通过采集到的电压和电流计算台灯的功率,避免台灯功率超过预设值,保证台灯寿命。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto
