实施例 1 :
下面结合图 1-3对本发明的实施例 1进行详细说明。本实施例的照明灯 具包括外壳 1、 LED2、 透明部 31和导光部 32， 所述 LED2、 所述透明部 31 和所述导光部 32设置在所述外壳 1内， 所述导光部 32包括出光面， 在本实 施例中， 所述导光部 32的出光面为所述导光部 32的离所述 LED2较远的端 面 B，所述 LED发出的光线从所述导光部 32的出光面及所述透明部 31出射。 在本实施例中， 所述导光部 32由透明材料制成。 所述透明部 31也由透明材 料制成。 在本实施例中， 所述透明部 31和导光部 32—体成型， 由透明材料 制成， 如由玻璃、 透明亚克力等制成， 这样可以减少灯具的零部件数量， 便 于安装。 在本实施例中， 所述导光部 32包括依次连接的壁， 所述导光部的 壁围成光出射的通道，所述 LED2的部分光线经过所述透明部 31出射后再穿 过所述通道，所述 LED2的另一部分光线经过导光部后从导光部 32的离所述 LED2较远的端面 B出射， 这样， 本实施例的照明灯具具有由导光部 32的离 所述 LED2较远的端面 B构成的环带状出光面以及由透明部 31的表面 A构成 的出光面， 照明灯具的出光面具有丰富的层次感和立体感。 所述导光部 32 的出光面是能使所述光线发生扩散的出光面，将出光面进行磨砂或者蚀纹等 方式处理， 使其变得粗糙， 即可使出光面变成具有扩散光线作用的出光面。 所述导光部 32的朝向所述通道的一侧表面 D和远离所述通道的一侧表面 E 均为全反射面， 这样， 进入导光部 32的光线经全反射面多次反射后都从导 光部 32的端面 B出射， 可以提高导光部 32的出光面的亮度， 可以通过调节 表面 D和表面 E跟 LED2的角度和位置关系， 使表面 D和表面 E成为全反射 面， 使进入所述导光部的光经全反射面反射到出光面出射。 所述照明灯具还 设有反射器 9，所述 LED2发出的部分光线经所述反射器 9反射后进入所述导 光部 32， 这样可以增加进入所述导光部 32的光线的光通量， 提高导光部 32 的出光面的亮度。 所述反射器 9设置于所述 LED2的侧方。 为了防止进入所 述导光部 32的光线从导光部 32的远离所述通道一侧表面 E出射， 所述照明 灯具还可以设有紧贴所述导光部 32的远离所述通道一侧表面 E的反射部（图 中未示出）， 例如， 在该表面粘贴一个漫反射膜。本实施例的照明灯具具有 2 个呈阶梯分布的出光面， 即所述透明部 31的离所述 LED2较远的表面 A和所 述导光部 32的离所述 LED2较远的端面 B， 从而使照明灯具具有丰富的层次 感和立体感。
通过设置透明部和导光部，所述 LED发出的光线部分从所述透明部出射， 部分从导光部的出光面出射， 即 LED发出的光线从多个面出射， 使照明灯具 的光线具有丰富的层次感、 立体感， 跟现有技术中的单一出光面的照明灯具 相比， 更加美观。 ' 实施例 2:
下面结合图 4-7对本发明的实施例 1进行详细说明。本实施例的照明灯 具包括外壳 1、 LED2、 透明部 31和导光部 32， 所述 LED2、 所述透明部 31 和所述导光部 32设置在所述外壳 1内，所述导光部 32包括出光面，所述 LED 发出的光线从所述导光部 32的出光面及所述透明部 31出射。在本实施例中， 所述导光部 32围成光出射的通道，所述 LED2的部分光线经过所述透明部 31 出射后再穿过所述通道。 所述导光部 32朝向所述通道一侧设有一个台阶面 C， 所述台阶面 C和所述导光部 32的离所述 LED2较远的端面 B为出光面。 这样，本实施例的照明灯具具有由导光部 32的离所述 LED2较远的端面 B构 成的环带状出光面、 由台阶面 C构成的环带状出光面以及由透明部 31的表 面 A构成的出光面， 照明灯具的出光面具有丰富的层次感和立体感。 在本实 施例中，所述导光部 32由透明材料制成。所述透明部 31也由透明材料制成。 在本实施例中， 所述透明部 31和导光部 32—体成型， 由透明材料制成， 如 由玻璃、 透明亚克力等制成， 这样可以减少灯具的零部件数量， 便于安装。 本实施例的照明灯具具有由导光部 32的离所述 LED2较远的端面 B构成的环 带状出光面、 由台阶面 C构成的环带状出光面以及由透明部 31的表面 A构 成的出光面，照明灯具的出光面具有丰富的层次感和立体感。所述导光部 32 的上述 2个出光面是能使所述光线发生扩散的出光面，将出光面进行磨砂或 者蚀纹等方式处理， 使其变得粗糙， 即可使出光面变成具有扩散光线的出光 面。 所述导光部 32的远离所述通道的一侧表面 E为全反射面， 所述导光部 的朝向所述通道的一侧表面除所述台阶面以外的部分 D为全反射面， 这样， 进入导光部 32的光线经全反射面多次反射后都从导光部 32的上述两个出光 面出射，可以提高导光部 32的出光面的亮度，可以通过调节表面 D和表面 E 跟 LED2的角度和位置关系， 使表面 D和表面 E成为全反射面。 所述照明灯 具还设有反射器 9，所述 LED2发出的部分光线经所述反射器 9反射后进入所 述导光部 32， 这样可以增加进入所述导光部 32的光线的光通量， 提高导光 部 32的出光面的亮度。 所述反射器 9设置于所述 LED2的侧方。 为了防止进 入所述导光部 32的光线从导光部 32的远离所述通道一侧表面 E出射，所述 照明灯具还可以设有紧贴所述导光部 32的远离所述通道一侧表面 E的反射 部 （图中未示出）， 例如， 在该表面粘贴一个漫反射膜。
作为实施例 2的简单变形， 可以仅导光部 32的台阶面 C设置为出光面; 而将导光部的端面 B设置为非出光面， 可以在其端面 B设置不透光的材料如 金属， 或者通过其它手段实现。
作为实施例 2的另一种简单变形， 所述导光部 32也可以设置多个台阶 面， 将所有的台阶面都设置为出光面。
通过设置透明部和导光部，所述 LED发出的光线部分从所述透明部出射， 部分从导光部的出光面出射， 即 LED发出的光线从多个面出射， 使照明灯具 的光线具有丰富的层次感、 立体感， 跟现有技术中的单一出光面的照明灯具 相比， 更加美观。
