点光源是一个点发出的光亮，而这个点发出光还同时具有另一个重要特征，那就是只有一方向上有光。LED是点光源，不同于目前市场上的节能灯或白炽灯。</div><div><br></div><div><p style="text-align: center;"><a href="data/attachment/portal/201704/19/111651v4i3rz8nkkmjzz3c.jpg" target="_blank"><img src="data/attachment/portal/201704/19/111651v4i3rz8nkkmjzz3c.jpg"></a></p></div><div><br></div><div> 如果我们想要用这种特殊的光来做<a href="http://light.oecr.com" target="_blank" class="relatedlink">照明</a>使用，就必须对这个光进行一定的处理，才可以达到我们的要求和目的，所以我们要加上<a href="http://opticaldesign.oecr.com" target="_blank" class="relatedlink">光学设计</a>，把这个相对集中的点光源变成具有一定角度的散光，草帽LED是专业用于照明设计的一种封装形式，一方面它可以让光线从一个集中的点光源变成具有一定角度的散光源，另一方面，它具有更少的光衰效果，而让更多的光透射出来为我们所用。<span style="line-height: 1.8em;">虽然草帽LED在光学角度上有了质的飞跃，但相对我们所熟悉的面光源来讲，它依旧是一个点光源，因其亮度过于集中，如果人眼直接看向光源，还是会对我们的眼睛造成一定的伤害。</span></div><div><br></div><div> 所以在LED照明应用于家庭照明灯中，我们还要进一步进其光线进行处理，再增加一定的光学设计，让其更加优化。而达到人眼可以直接观测的目的，同时柔和光线，另一方面还要再次放大其照射角度，虽然草帽LED本身已经做到120度范围，但如果直接应用于家庭照明，给我们的感觉是屋顶上表现出来是一片漆黑，我们要利用灯具最外面的透明罩把光线再次分散开来，从而适应正常的家庭照明。</div><div><br></div><div> 由南京光研代理的ZEMAX是一套综合性的光学设计<a href="http://opticaldesign.oecr.com" target="_blank" class="relatedlink">软件</a>。它提供先进的、且符合工业标准的分析、优化、公差分析功能，能够快速准确的完成光学成像及照明设计。可以对各种LED二次配光透镜，色度分析及颜色混合优化，也可以对LED等照明系统设计优化。</div><div><br></div><div>
