低温 LED照明供电装置
技术领域
本发明涉及一种低温 LED照明供电装置，尤指具有一低耗能供电控制模块及一 LED 发光模块电气连接而成， 可让 LED照明设备适用于较宽广的供电范围， 并能维持于低 温、 低耗能状态下工作， 以符合经济实用及环保要求的照明供电装置。 背景技术
灯光是现代生活中不可缺乏的主要照明设备， 随着科技进步技术日益成熟， 新一 代的 LED具有高亮度、 反应快、 体积小、 低耗电量、 节能、 使用安全及寿命长的优点， 故业界均积极开发 LED照明来取代传统照明。
但因为高功率 LED输入功率仅有 15-20%转换成光， 其余 80-85%则转换成热； 这些 热能若未有效加以处理适时排出， 将会使 LED晶粒界面温度过高， 而导致发光效率衰 减、 寿命降低等问题， 是影响 LED照明相关产品的优劣关键。
现有常见的 LED照明设备是选用 12V或 30V DC电子式变压器， 将 100V- 260V AC 转 12V DC/300-500 mA或 30V DC/300-500 mA， 以配合 LED光源， 使用时除了产生热 源高达 60 °C以上； 还会形成高温剌眼的眩光 （gl are)。 而且现有 LED照明的 AC电源 输入端电流为数 10 mA以上， 从低温、 低耗能、 低碳的环保要求， 有许多技术需要提 升。 另外， 电子式变压器充满主动性元件， 对于浪涌的干扰免疫能力很差， 容易发生 故障。
针对上述 LED照明高温现象的解决方法， 目前所衍生较先进的专利技术， 基本上 都是采用材料来降温： 例如中国台湾公告第 M420646号 LED的散热照明装置、 中国台 湾公告第 M423204号高效散热的 LED灯具、中国台湾公告第 1263008号发光二极管灯、 中国台湾公告第 1359243号具散热效果的 LED灯具、中国申请第 200680019064号散热 器灯及制造散热器的方法、 中国申请第 200810067522号发光二极管灯具、 中国申请第 201010125449号一种 LED路灯、 美国专利第 US7497596B2 号 LED AND LED LAMP , 美 国专利第 US8076856B2号 LED LAMP , 日本特开第 JP2010050472A号発光夕 才一 卜" ■
7 7。及 発光夕' 才一 K交通灯（中译： 发光二极管及交通灯）、 及日本特开第
JP2004288827A号 LED 7 7° (中译： LED灯）等， 其结构设计虽然都能达到一定的散热 效果，但事实上仍无法完全克服 LED发光产生高热的问题，依现有技术要解决单颗 LED 灯泡散热问题都已经十分麻烦了， 如果一旦 LED光源采用矩阵排列时， 聚集所产生的 热源温度将会更高， 使后续处理成本跟着加倍增高， 不符经济效益。
此外， 目前 LED 照明所采用的 AC电压都是限制于 100V-260V以下， 有效工作电 压范围相当受限， 无法直接与太阳能或风力发电接结合成为供电独立的照明系统， 也 是其一项缺点。

以下配合图示列举具体实施例， 详细说明如下：
请参图 1-3所示， 本发明所设的低温 LED照明供电装置 1， 其主要包括： 一低耗 能供电控制模块 10及一 LED发光模块 20电气连接而成；其中该 LED发光模块 20由至 少一光源驱动器 21与一 LED光源 22所构成； 而该低耗能供电控制模块 10， 至少具有 一浪涌抑制单元 11、 一分压限压单元 12、 一电流限定单元 13、 及一稳压滤波单元 14 所构成； 其中
该浪涌抑制单元 11， 对外以连接输入电压， 至少由浪涌保护元件 111、 电感 112 与电容 113所构成， 用以抑制浪涌， 并将浪涌能量转换成电压； 使本发明应用于工业 照明、 商业照明、 路灯照明时， 对于大容量断路器切换时所产生的开关浪涌可以有效 抑制， 即使在连续电弧（arc)的干扰环境下依然可以正常使用。
该分压限压单元 12， 与浪涌抑制单元 11电气连接， 至少由两群电容 121所构成， 以允许较大 AC输入电压范围， 实施时， 并可经特殊设计规划成指数型态（同参图 4)使 适用在 60V至 900V, 而输出工作电压限制在特定范围， 达到全电压功能， 使其应用上 供电范围需求更为宽广； 其中输入电压若采用三相系统， 如 380V、 420V及 480V等， 均可由 L-N接线使用。
该电流限定单元 13， 与分压限压单元 12电气连接， 至少由一变压器 131搭配前 述分压限压单元 12所构成， 将输入电流限制在 10mA上下的一般电气泄漏电流范围， 达到低耗能功能。
该稳压滤波单元 14， 与电流限定单元 13电气连接， 至少由浪涌保护元件 141、 电 感 142与电容 143所构成，滤除残存干扰浪涌以保护其后所接 LED发光模块 20的光源 驱动器 21。
该光源驱动器 21电气连接一 LED光源 22， 结合前面低耗能控制单元 10， 可以达 到降低 LED光源 22的自身热源， 使其所接的 LED 光源 22处于低温状态。
如图 3所示， 为本发明以一低耗能供电控制模块 10搭配一 LED发光模块 20所制 成的单颗产品， 其技术已达成熟量产商品化阶段， 产品应用启动的时间快， 从 AC电源 开关投入后， 到 LED光源 22全亮所需的反应时间只需 6-7 μ Sec , 眼睛无闪烁的感觉。 于本图虽仅列举圆形及长条形的 LED光源 22， 但实际应用并不以此限， 其外观造形还 可有多种变化， 以适应各种不同需求。
请参图 4-6所示， 为本发明图 3中单颗产品的相关实验测试数据。 从图 4表中内 容可知本发明所允许 AC电压输入范围由 60V至 900V, 而输出电压维持在 9. 5V上下。 从图 5表中内容可知本发明所消耗的 AC输入电流量约为 10mA， 其最佳的数值可将其 限定在 10mA+10%上下， 低于一般电气设备泄漏电流； 而输出电流量约低于 80mA。 从图 6表中内容可知本发明整体温度虽维持在 30 °C， 但最佳的数值可将其限定在 30 °C + 10% 上下， 确实可构成低温照明装置。 由图 4-6所示， 可充份证明本发明确实符合低温、 低耗能、 低碳的环保要求， 是照明领域的重大技术突破， 具有独创性、 新颖性、 进步 性。
其中， 特别值得一提如图 1、 图 4所示， 因为本发明所设的指数型态分压限压单 元 12， 可将 AC输入电压范围由 60V至 900V的输入负载电流限制在 10mA上下范围， 故使单颗产品的低耗能供电控制模块 10可呈现低温状态： 另外， 如图 1、 图 5所示， 因为低耗能供电控制模块 10输出电流系被限制在 80mA (明显低于 100mA以下）， 故使 LED发光模块 20光源的热能也可明显降低控制在 30 °C上下；因为该两者低耗能供电控 制模块 10及 LED发光模块 20都被妥善控制在低温状态下正常工作， 故其组成的单颗 产品应用时热源温度即可低于一般人体正常体温。
基于此， 如图 1、 图 8所示， 使本发明实际应用时， 可由多个低耗能供电控制模 块 10搭配多个 LED发光模块 20电气连接成多个单颗产品， 排列制成一 LED光源矩阵 23； 或如图 9所示， 也可将多个低耗能供电控制模块 10及多个 LED发光模块 20分开 各设成一独立的电路板， 中间再以排线相连， 而制成一 LED光源矩阵 23， 这两种方式 同样都可在低温状态下正常工作， 其技术已达成熟量产商品化阶段， 于本例中的 LED 光源矩阵 23虽仅揭露以长条 LED光源 22所制成 （但实际其分布状态及排列方式并不 以此为限）； LED光源矩阵 23上的每一单颗产品的实验测试数据同上（于此不再赘述）， 而整体应用照度的实验测试数据如图 7所示， 以 LED光源矩阵 23平均分布在 420cm X 60 cm 面积范围， 在高度 180cm的位置量测照度， 面积范围中心位置最佳照度为 680Lux/mm2 ; 面积范围边缘位置最低照度为 480Lux/mm2。
本发明应用时具有如下优点：
1.本发明的低温 LED照明供电装置 1仅消耗数 mA电流量，而温度又明显低于现有 现有一般 LED照明温度、 可避免周围环境温度升高， 而减少冷气空调的使用， 大幅降 低电力使用， 对于碳排放量的减低程度， 远胜过于目前市面上 LED照明结构， 可真正 逹到降温、 节能、 减碳等环保功能， 是照明领域的重大突破。
2.本发明的工作电压经特殊规划设计， 可允许 AC电压范围由 60V至 900V, 除了 与一般供电系统配合应用， 更可以与太阳能供电设施 30 (如图 10)、风力机组发电设施 40 (如图 1 1)、 汽车 DC转换 AC装置 50 (如图 12)、 手持式照明装置电源等， 直接连接 使用。
3.本发明的光源由点到面分布均可， 尤其制成的矩阵排列光源照度十分均匀， 可 有效提供工业照明、 商业照明、 农业照明、 美术照明与家庭照明使用、 或路灯照明 60 使用（如图 13)。
以上实施例仅为方便说明而公开， 并非用以限定本发明， 任何熟习此应用者， 当 可做各种更动与不同的应用， 其本质未脱离本发明的精神范畴者， 皆当包含在本发明 专利范围保护中。
