Description

类荧光 LED照明单体及用途
技术领域
本发明涉及 LED照明 /信号灯具，特别涉及一种效果类似并优异于现有 日光灯荧光效果的 LED照明单体。 本发明还涉及该类荧光 LED照明单体的 用途。 背景技术
与传统的白炽灯、 日光灯等照明灯具相比， LED照明灯体具有寿命长、 光效高、 功耗低和无荧光粉污染等特点， 具有很高的替代性。 但是现有可 供照明用的 LED灯管， 其均在灯管的管体内设置电路板和 LED阵列， LED 发光体一般沿管体轴向方向排布， LED发光体的出光中心朝向管体的管壁， 这样的 LED 日光灯存在点状光源显露， 光路照射角度小， 组合成日光灯的 LED点状光源成串珠形， 光线刺眼， 与现有日光灯出光模式差异太大， 且多 光点照射对被照射物体在墙面或地上所形成的投影为多重叠影而使人看了 眩晕， 不符合人们长期养成的对传统日光灯的使用感觉， 舒适性不够而不 适合用做生活照明。
为了使 LED照明灯体的出光模式接近于现有的日光灯， 有许多发明者 致力于 LED照明灯体的出光模式的研究， 形成了很多专利。
如一种比较典型的方案其在 LED灯管两端分别为相向设置有二个 LED 发光体，在管体内设置有双面反光片或导光材料或光反射材料， LED发光体 发出的光通过双面反光片或光反射材料反射出来或者通过导光材料散射出 来， 以尽量接近现有日光灯的出光模式， 这类典型方案有如中国发明专利 公开号 CN101144591A公开的 LED 日光灯， 中国实用新型专利授权公告号 CN200993322Y公开的 LED日光灯等， 但是这类 LED日光灯由于采用 LED发 光体数量少， 其光照也不是很强， 很难适应日常照明使用。
还如一种比较典型的方式是在注塑灯管过程中将一定量的散光粉或导 光粉均匀混入 PC或 PV灯管原材料中，注塑成中空式灯管， LED发光体发出 的光通过 PC或 PV灯管透射出来， 这类专利有如中国实用新型专利授权公 告号 CN201293218Y公开的柔和多发光角度的 LED日光灯，但是该类 LED日 光灯仍然无法解决 LED 日光灯存在点状光源显露， 光路损失大， 灯具照度 不够等问题。
还如一种比较典型的方式是采用加装透镜的 LED发光体， 如中国实用 新型专利授权公告号 CN201330956Y公开的一种大功率 LED日光灯，但是该 类 LED日光灯仍然没能很好解决 LED日光灯存在上述有关问题。 发明内容
本发明所要解决的是针对上述 LED日光灯所存在的技术问题而提供一 种更接近传统荧光灯的 LED照明单体及其利用该 LED照明单体所制备的适 合生活用照明灯具， 其光色和出光均匀度以及柔和性与现有荧光灯基本无 差异， 符合人们长期养成的使用习惯和认同。 根据光的利用效率之定义， 由于本发明所涉 LED照明单体所采用的光学模型它的出射光具有一定的指 向性,其所照明的有效面积内的光通量与光源光通量的比值较高而使该灯 具相对于传统荧光灯它的光利用率更高。
本发明所要解决的技术问题可以通过以下技术方案来实现：
