本发明关于大功率 LED 照明技术领域， 尤其是涉及一种包括一风扇以改进散 热的大功率 LED照明装置。 背景技术
现有技术中， 大功率 LED照明装置常见以各种的使用方式而应用于各式场合。 举例而言， 像是于捕渔时使用的集鱼灯， 对广场提供照明的广场灯， 对隧道提供照 明的隧道灯， 对道路提供照明的路灯， 对广告牌提供照明的广告灯， 以及俗称 PAR 灯的筒灯等。
现有技术中， 大功率 LED照明装置包括 LED灯组和铝散热器， LED灯组贴设 于铝散热器。 而大功率 LED照明装置执行照明时， 因 LED灯组产生的热量较多， 故 LED灯组的温度容易过高， 因此， 大功率 LED照明装置需要设置散热器等散热 装置， 以降低 LED灯组的温度。但是，现有技术中，大功率 LED照明装置仅在 LED 灯组的背面贴设铝散热器， 铝散热器虽然具有一定的散热效果， 但是铝散热器的热 传导速度较慢， 散热速度仍然不能满足大功率 LED 照明装置的散热要求， 故大功 率 LED照明装置的散热效果仍不理想， 因此有必要予以改进。
如中国台湾专利号 M359801 揭露一种发光二极管散热装置， 其虽然具有一风 扇单元， 但其鳍片单元呈放射状， 故与 LED 单元的接触面积小， 导热效果较差。 再者， LED 单元被陶瓷、 塑料或树指的密封材料密封于鳍片单元的承载部上， 故 LED单元并无法与周边空气作气体交换， 故风扇单元的空气对流效果有限。
另外，前述专利中所揭露的风扇单元，其是将鳍片单元所传导与散发出来的热， 以空气对流方式向外部排出， 因此风扇单元仍是将所吸入的热空气向外部排放， 而 非自外部引入大量冷空气来冷却鳍片单元， 是以， 前述专利中所揭露的此等习知做 法， 恐将已无法应付大功率 LED所散发出来的高热问题。
有鉴于此， 提供一种大功率 LED 照明装置， 其具有良好对流及散热效果同时 能提供足够照明亮度， 此乃为业界亟待解决的问题。 发明内容

请先参阅图 1以及图 2， 图 1为本发明大功率 LED照明装置为一筒灯的内部结 构示意图； 图 2为本发明大功率 LED照明装置为一筒灯的分解示意图。
于此须先说明者为， 本发明的大功率 LED 照明装置通常应用于一户外灯和一 商业照明灯中的至少一者。 该户外灯可以为一集鱼灯、 一广场灯、 一路灯、 一隧道 灯以及一广告灯其中的至少一者， 该商业照明灯可以为筒灯以及广告灯其中的至少 一者。 于本发明的第一实施例中， 本发明的大功率 LED照明装置为一筒灯 1， 筒灯 1包括一具有上壳体与下壳体的外壳 11、 一 LED灯组 14、 一散热器 12以及一风扇 13。 LED灯组 14设置于散热器 12上， 较佳为 LED灯组 14整片平贴于散热器 12 上， 使 LED灯组 14发亮时产生的热量传导至散热器 12， 以降低 LED灯组 14的温 度。 其中， LED灯组 14、 散热器 12以及风扇 13皆被固定于外壳 11的下壳体内。
于一较佳实施态样中， 风扇 13固定于散热器 12; 抑或， 于另一较佳实施态样 中， 风扇 13固定于外壳 11的下壳体。 换句话说， 风扇 13固定于散热器 12和外壳 11的下壳体中的至少一者， 并且， 风扇 13吹出的气流方向是直接朝向散热器 12吹 送。藉此设置，即能加速散热器 12周遭的空气对流，并同时提高散热器 12以及 LED 灯组 14的散热速度。 如此一来， 即可使 LED灯组 14长时间保持在较低的温度， 藉以进一步提高 LED灯组 14的发光效率， 并延长筒灯 1的使用寿命。
进一步而言， 外壳 11的下壳体具有至少一通气孔 110， 通气孔 110较佳为设置 于外壳 11的下壳体的一环周面上，使位于外壳 11内及位于外壳 11外的内外气体可 经由至少一通气孔 110相互连通。 藉此， 再结合风扇 13能主动吹动气体， 即能使 外壳 11外的气体被吸进外壳 11内，而达到冷热气体混合交换而降温的目的。此外， 制造者亦可将风扇 13 以一流体冷却系统 （图未示） 作替换， 而此两者皆属于主动 散热手段。 至于散热器 12则可另外连接 /替换一热管或散热鳍片， 此三者皆属于被 动散热手段。
当然， 为避免来自一外界的液体经通气孔 110进入至外壳 11 内， 于本实施态 样中， 筒灯 1更包括一防水手段（图未示）， 较佳为设置于外壳 11外围， 以防止液 体自该外界经由至少一通气孔 110流入外壳 11 内， 并使筒灯 1 内部电路维持良好 运作。
详细而言， LED灯组包括一 PCB板 144以及多个 LED灯珠 142， 各 LED灯珠 142分别固定于 PCB板 144的表面； 其中， PCB板 144为一柔性 PCB板和一硬式 PCB板中的任一者。 若 PCB板 144为一柔性 PCB板， 则因其导热速度更快， 故积 聚的热量较少， 因此柔性 PCB板具有较低的温度。
再者， 筒灯 1还包括一人体感应元件 （图未示） 及 /或一光敏电阻 （图未示）， 且该人体感应元件及 /或该光敏电阻电连接于该柔性 PCB板或该硬式 PCB板上。藉 此设置，能够藉由该人体感应元件来判断筒灯 1附近是否有行人走动或物体运动等， 若有， 则开启照明； 抑或， 藉由该光敏电阻来判断周遭环境明暗， 若过暗， 则开启 照明。
风扇 13电连接于一电源控制电路 （图未示）， 即由电源控制电路对风扇 13进 行供电并控制风扇 13的工作状态。 此外， 散热器 12为由铝材制成的铝散热器、 由 锂镁合金制成的片状的锂镁合金散热器和由铝镁合金制成的片状的铝镁合金散热 器中的一种或两种以上的组合。
除此之外，基于组装方便上的考虑， 外壳 11较佳为由一上壳体 111和一下壳体 112组装而成。 另一方面， 为考虑成本， 像是散热器 12设置为铝散热器、 锂镁合金 散热器和铝镁合金散热器中的两种以上的组合， 制造商可视情形调整比例， 以把持 成本。 请再参阅图 3以及图 4， 图 3为本发明大功率 LED照明装置为一集鱼灯的内部 结构示意图； 图 4为本发明大功率 LED照明装置为一集鱼灯的分解示意图。
于第二实施例中， 本发明的大功率 LED照明装置为一集鱼灯 2， 相似于第一实 施例的筒灯 1， 集鱼灯 2包括一具有上壳体与下壳体的外壳 21、 一 LED灯组 24、 一散热器 22以及一风扇 23。 LED灯组 24贴设于散热器 22， 将 LED灯组 24发亮 时产生的热量朝散热器 22传导， 以降低 LED灯组 24的温度。其中， LED灯组 24、 散热器 22以及风扇 23皆被固定于外壳 21内。
又， 风扇 23是被固定于散热器 22; 抑或， 于另一较佳实施态样中， 风扇 23 可改固定于外壳 21的下壳体。 换句话说， 风扇 23可固定于散热器 22和外壳 21的 下壳体中的至少一者；至于其它细部实施态样则相同于第一实施例，于此不再赘述。
当然， 于集鱼灯 2的外壳 21处， 也可设置如第一实施例中所述的至少一通气 孔 （图未示）， 以结合风扇 23主动吹动气体， 使外壳 21外的气体能被吸进外壳 21 内， 并且， 风扇 23吹出的气流方向是直接朝向散热器 22吹送， 以达到冷热气体混 合交换而降温的目的； 更佳者， 为避免来自一外界的液体经通气孔进入至外壳 21 内， 于本实施态样中， 集鱼灯 2更包括一防水手段 （图未示）， 较佳为设置于外壳 21外围， 以防止液体自该外界经由至少一通气孔流入外壳 21内， 并使集鱼灯 2内 部电路维持良好运作。
请再参阅图 5以及图 6， 图 5为本发明大功率 LED照明装置为一路灯的内部结 构示意图； 图 6为本发明大功率 LED照明装置为一路灯的分解示意图。
于第三实施例中， 本发明的大功率 LED照明装置为一路灯 3， 相似于第一实施 例的筒灯 1， 路灯 3包括一具有上壳体与下壳体的外壳 31、 一 LED灯组 34、 一散 热器 32以及一风扇 33。 LED灯组 34贴设于散热器 32， 将 LED灯组 34发亮时产 生的热量朝散热器 32传导， 以降低 LED灯组 34的温度。 其中， LED灯组 34、 散 热器 32以及风扇 33皆被固定于外壳 31内。
又， 风扇 33可被固定于散热器 32和外壳 31的下壳体的至少一者； 至于其它 细部实施态样则相同于第一实施例， 于此不再赘述。
与前述各实施例不同之处在于， 外壳 31的上壳体的表面积可小于外壳 31的下 壳体的表面积， 以于两者组装于一起时 （如图 5所示者）， 可以留出一个较大的空 隙 310， 以作为如前述各实施例中所述的至少一通气孔使用， 如此， 即可结合风扇 33主动吹动气体， 使外壳 31外的气体能被吸进外壳 31内， 并且， 风扇 33吹出的 气流方向是直接朝向散热器 32 吹送， 以达到冷热气体混合交换而降温的目的； 更 佳者， 为避免来自一外界的液体经通气孔 310进入至外壳 31内， 于本实施态样中， 路灯 3更包括一防水手段（图未示）， 较佳为设置于外壳 31外围， 以防止液体自该 外界经由通气孔 310流入外壳 31内， 并使路灯 3内部电路维持良好运作。
当然， 若外壳 31的上壳体的表面积约略等于外壳 31的下壳体的表面积时 （图 未示）， 至少一通气孔则可如前述各实施例中所述般， 改设置于外壳 31处， 于此即 不再赘述。

又， 风扇 43可被固定于散热器 42和外壳 41的后壳体的至少一者； 至于其它 细部实施态样则相同于第一实施例， 于此不再赘述。
更佳者， 为避免来自一外界的液体经通气孔进入至外壳 41 内， 于本实施态样 中， 广告灯 4更包括一防水手段（图未示）， 较佳为设置于外壳 41外围， 以防止液 体自该外界经由通气孔 410流入外壳 21内， 并使广告灯 4内部电路维持良好运作。
请再参阅图 10以及图 11， 图 10为本发明大功率 LED照明装置为一隧道灯的 结构示意图； 图 11为本发明大功率 LED照明装置为一隧道灯的分解示意图。
于第五实施例中， 本发明的大功率 LED照明装置为一隧道灯 5， 相似于第一实 施例的筒灯 1， 隧道灯 5包括一具有上壳体与下壳体的外壳 51、 一 LED灯组 54、 一散热器 52以及一风扇 53。 LED灯组 54贴设于散热器 52， 将 LED灯组 54发亮 时产生的热量朝散热器 52传导， 以降低 LED灯组 54的温度。其中， LED灯组 54、 散热器 52以及风扇 53皆被固定于外壳 51内。
又， 风扇 53可被固定于散热器 52和外壳 51的下壳体的至少一者； 至于其它 细部实施态样则相同于第一实施例， 于此不再赘述。
当然， 于隧道灯 5的外壳 51处， 也可设置如第一实施例中所述的至少一通气 孔 （图未示）， 以结合风扇 53主动吹动气体， 使外壳 51外的气体能被吸进外壳 51 内， 并且， 风扇 53吹出的气流方向是直接朝向散热器 52吹送， 以达到冷热气体混 合交换而降温的目的； 更佳者， 为避免来自一外界的液体经通气孔进入至外壳 51 内， 于本实施态样中， 隧道灯 5 更包括一防水手段 （图未示）， 较佳为设置于外壳 51外围， 以防止液体自该外界经由至少一通气孔流入外壳 51内， 并使隧道灯 5内 部电路维持良好运作。

于第六实施例中， 本发明的大功率 LED照明装置为一广场灯 6， 相似于第一实 施例的筒灯 1， 广场灯 6包括一具有上壳体与下壳体的外壳 61、 一 LED灯组 64、 一散热器 62以及一风扇 63。 LED灯组 64贴设于散热器 62， 将 LED灯组 64发亮 时产生的热量朝散热器 62传导， 以降低 LED灯组 64的温度。其中， LED灯组 64、 散热器 62以及风扇 63皆被固定于外壳 61内。
又， 风扇 63可被固定于散热器 62和外壳 61的下壳体的至少一者； 至于其它 细部实施态样则相同于第一实施例， 于此不再赘述。
当然， 于广场灯 6的外壳 61处， 也可设置如第一实施例中所述的至少一通气 孔 （图未示）， 以结合风扇 63主动吹动气体， 使外壳 61外的气体能被吸进外壳 61 内， 并且， 风扇 63吹出的气流方向是直接朝向散热器 62吹送， 以达到冷热气体混 合交换而降温的目的； 更佳者， 为避免来自一外界的液体经通气孔进入至外壳 61 内， 于本实施态样中， 隧道灯 6 更包括一防水手段 （图未示）， 较佳为设置于外壳 61外围， 以防止液体自该外界经由至少一通气孔流入外壳 61内， 并使隧道灯 6内 部电路维持良好运作。
