具体实施方式
为详细说明本发明的技术内容、构造特征、所实现目的及效果，以下结合实施方式并配合附图详予说明。
请参阅图 1 至图 3 ，本实施方式为一种 LED 台灯，其包括 LED 电源、 LED 基板 7 和安装在 LED 基板 7 上的 LED 芯片 6 ， LED 电源与 LED 芯片 6 电连接。所述 LED 基板 7 呈空心的圆筒状， LED 芯片 6 均布在 LED 基板 7 的外表面上，沿轴向排列的多个 LED 芯片 6 为一芯片组，所述芯片组具有 12 ～ 20 组，芯片组以 LED 基板 7 的轴心为中心轴对称布置。相邻的两芯片组之间设有向外辐射延伸的隔板 3 ， LED 基板 7 和隔板 3 为采用铝合金制成的一体成型件。隔板 3 的末端连接有折光板 2 ，隔板 3 和折光板 2 之间的连接角度为 18° ～ 30° ，折光板 2 采用半透明的乳白色 PMMA 材料制成，折光板 2 可从隔板 3 上单独拆卸下来。 LED 芯片 6 发出的光不直接作为照明光使用，而需先照射到折光板 2 上，其中大部分光折射到 LED 灯前面，小部分光通过折射或透射到周围的空间。这样既能满足灯前面的照明要求，又能使灯背后空间由柔和光包围，人的眼睛不会感觉刺眼或炫目，在这样光照环境下工作时眼睛不易产生疲劳。 LED 基板 7 设计为中空形状，在中心处形成一个热对流通道，工作时利用烟囱效应， LED 芯片 6 产生的热量散发在空气中，热空气通过该热对流通道上浮，能有效将 LED 芯片 6 产生的热量带走。可拆卸的折光板 2 有利于减小产品包装盒尺寸。
所述 LED 基板 7 的一端固定有盖板 1 ，另一端连接有灯柱 5 和亮度调节装置 4 ，灯柱 5 的末端连接有一底座 8 ，亮度调节装置 4 包括用于调节照明角度和强度一个调亮旋钮 41 和一个调暗旋钮 42 ，亮度调节装置 4 和所述 LED 电源电连接。调亮旋钮 41 和调暗旋钮 42 上分别设有多个卡位，调亮旋钮 41 上的卡位用于导通所述 LED 电源和芯片组的电连接，调暗旋钮 42 上的卡位用于断开所述 LED 电源和芯片组的电连接。亮度调节装置 4 可分别对 LED 电源进行导通或切断的控制，对每个芯片组指定单一序号，调亮旋钮 41 从第一芯片组开始依次连续开启芯片组，调暗旋钮 42 也从第一芯片组开始依次连续关闭芯片组，通过调亮旋钮 41 和调暗旋钮 42 的相互配合，可以单独点亮任意一组或连续多组芯片组，实现 LED 灯头中任意位置的芯片组的开闭。具体地，调亮旋钮 41 顺时针转动一个卡位，可多导通加一组 LED 电源和芯片组的电连接，即多点亮一芯片组；调暗旋钮 42 顺时针转动一个卡位，可断开末组 LED 电源和芯片组的电连接，即熄灭一末组芯片组。
请参阅图 4 ，图 4 为本发明作为床头灯的实施方式，在该实施方式中，所述底座 8 可固定在墙上，底座 8 和灯柱 5 的连接方式为铰接，灯柱 5 可根据需要改变与底座 8 之间的角度。
请参阅图 5 ，图 5 为本发明作为落地灯的实施方式，在该实施方式中，所述底座 8 安放在地面上，灯柱 5 具有较长的长度。
本发明的有益效果是： LED 芯片射出的光线经过折光板的折射大部分到达照明区域，小部分折射或透射到周边，使整个空间都存在微弱的光线，既保持光照系统的高效率，又有效减少了眩目，视觉效果获得改善，实现家庭照明的光源节能环保。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
