本发明涉及一种组合式大功率 LED灯， 是一种照明装置和所述装置的组 合形成的灯具， 是一种大功率 LED灯的灯座和组合的方式。
背景技术
随着 LED芯片技术和封装技术的发展,顺应照明领 LED产品的需要， LED逐步走入市场， 尤其是逐步应用在室内和室外各照明领域。 由于 LED是 点光源， 在应用时都要通过不同方式将其做成多个 LED光源串连或并联的模 块化光源来使用。 目前的整块式 LED光源模块都是由芯片直接组合而成的， 这种方式 起来存在以下问题， （ 1 )不能灵活的根据需要进行方便的组合成 不同样式的光源， 从而导致发^丁样式不能灵活改变； （2 )整个光源中若存在 一个点光源或几个点光源损坏时， 单个光源不能更换或不容易更换， 导致放弃 维修维护， 造成使用过程中光照度不均， 使亮度达不到设计要求， 若必须进行 维修则需要对整个灯具进行拆卸， 维修复杂且费用较高； （3 )由于 LED灯在 实际安装中通常采用串并联结合的方式， i 中个别 LED灯的性育 生变化， 致使串联电路的电压、 电流产生变化， 会使个别 LED灯亮度偏高， 发热量增 大， 造成容易烧坏的恶性循环； （4 ) 由于现有 化大功率 LED灯的芯片太 集中， 导½热量大和难散热。 这些都是造成使用寿命缩短和光源不稳定的因 素， 这也无形中增加了使用成本， 造成了没必要的浪费。
发明内容
为了克服现有技术的问题， 本发明提出了一种组合式大功率 LED灯。 所 述的组合灯座的每一个 LED灯芯具有独立的防水设施、 独立的散热设施和独 立的散光或聚光实施，可以通过互锁装置、 阴阳面偶合机构、连接杆、连接架、 等随意的进行花样多变的组合， 形成室内的支形吊灯、 盘形吊灯、 桶形吊灯， 以及各种形式的吸顶灯， 或室夕卜使用的各种路灯、 隧 丁、 广场灯、 嗇灯、 广告牌照射灯、 景 丁， 又或汽车灯等。
本发明的目的是这样实现的： 一种组合式大功率 LED灯， 包括： 至少一 个大功率 LED灯芯， 所述大功率 LED灯芯安装在与散热器一体的灯座体上， 所述的灯座体上围绕每一个大功率 LED灯芯设置有连接大功率 LED灯芯正负 电极的导电设施， 所述大功率 LED灯芯的出光面上设有密封设施， 所述密封 设施上有供大功率 LED灯芯出光的透光孔， 所述导电设施上连接有电源引出 线， 所述电源引出线穿 丁座体上的出线孔连接电源， 所述出线孔带有密封胶 圈或密封胶， 围绕每一个所述大功率 LED灯芯的外围周围设置有将大功率 LED灯芯的出光面和背光面联通的供散热的一个以上通气孔。
本发明产生的有益效果是： （ 1 )多个 LED光源模块单元灵活拼装在固 定支架上组成大功率 LED灯， 在实际安装设计中， 才艮据灯具形状需要设 计不同固定支架即可最终实现 LED灯的形状多样性， 且每个 LED光源模 块单元可以独立拆卸， 任何一个发生故障后可以方便快捷更换， 维修极 为方便； （ 2 )本发明所述的每个 LED光源模块单元上都具有散热结构， 从而解决了大功率 LED光源灯在工作时的散热问题， 尤其是有导热管或 回路式热管的散热结构的散热效果特别显著； （ 3 )本发明的每个模块单 元上考虑到该光源水下使用中的防水性， 在所有结构的密封连接处采用 了防水胶圈， 增强了 LED灯的防水性能。 本发明由于每一个 LED灯芯具有 独立的防水设施、 独立的散热设施和独立的散光实施， 使每个 LED灯芯类似 于一个低电压的灯泡， 可以随意的组合。 自从大功率 LED灯面世以来， 由于 大功率 LED灯的亮度不够、 电源、 散热和光线过于集中等问题， 人们已经习 惯于将多个 LED发光芯片集中使用方式。本发明突破了这一习惯，使单个 LED 灯可以独立使用， 甚至加上适当的电源可用作一个灯泡来看待； （4 )由于其配 光设施可以更换， 所以只需一次配光就可实现光谱的多样性， 从而节约了材料 和成本； （5 )由于釆用了集成灯体功能和简化灯体结构的设计思路， 使得其既 薄又轻且散热好， 成本也低， 再有其不需要进行二次开发便可实现长寿命的照 明级别的应用； （6 )由于其可以根据^ ί]环境的需要进行加固使用， 所以其具 有很强的抗风能力； （7 )在工程应用中， 其能根据现场对光照射角度的需要， 对个状或条状或块状灯的照射角度进^周节。

实施方式
实施例一：
本实施例是一种组合式大功率 LED灯， 如图 1所示组装成型的示意图， 图 2是分解图。本实施例包括： 至少一个大功率 LED灯芯 2 (本实施例中有时 为简化称为灯芯）。 本实施例所述的大功率 LED灯芯， 指的是功率在 1瓦以上 的大功率 LED灯芯。 所述的 LED灯芯在市场上被直接称为 LED灯， 或发光 及管。 本实施例为区别起见， 将这种市场上称为 LED灯的元件称为灯芯。 大功率 LED灯芯与小功率 LED灯芯在电极引线上有明显的区另1 j。小功率 LED 灯的引线在背光面， 是两条细金属线， 通常直接焊接在印刷线路板上。 而大功 率 LED灯芯的电 配^ it镜的两侧， 并且 片形金属片， 这是出于散热 的考虑才如此设计的。大功率 LED灯芯的构成如图 3所示， 包括配光透镜 203 中包含的发光晶片 202, 该发光晶片安 ^^一个热沉余支架 204上， 两根金丝 跳线连接发光晶片和安^ ^配 镜周围的电极支架 205上的电极 201。 这种 标准的大功率 LED灯芯的缺点是发光晶片的热量要通过热沉余支架传出， 而 热沉余支架与外部的散热器之间的结合往往不理想， 会产生较大的热阻， 影响 散热。 因此， 本实施例所述的大功率 LED芯片可以是一种没有热沉余支架的 LED灯芯。这种没有热沉余支架的 LED灯芯的发光晶片直接封^^灯座体上， 这样晶片 M出的热量可以直 导到外部的散热器上，所以热阻与热冗余很 小， 故其散热效率非常高， 如图 4所示。
本实施例通过更换灯芯的配光透镜， 一次配光就能实现光照样式的多样 化， 例如： 需 巨形光斑时， 就换上矩形光斑配光透镜； 需要不对称光斑时， 就换上不对称配光透镜。 、
大功率 LED灯芯安装在与散热器 6—体的灯座体 8上。 这是本实施例区 别于现有技术的关键。 大功率 LED灯与小功率 LED灯的一个明显的区别是大 功率 LED灯会产生大量的热量。 对于大功率 LED灯来说， 散热是一个十分重 要的问题， 必须妥善的解决， 否则大功率 LED灯根本无法正常工作。 现有的 大功率 LED灯的灯具限于结构的限制， 通常采用多个散热元件， 使热量在多 个散热元件之间传递， 将大功率 LED灯芯所发出的大量热量^^出去。 但由 于多个散热元件之间容易产生间隙， 热量在不同的媒介中传播， 热传导不十分 畅通， 容易产生热阻， 降低散热效率。 为最大限度的减小热阻， 本实施例所述 的灯座体本身带有散热器， 热量在一种介质中传播， 传播效率较高。 本实施例 所述的散热器可以是增大与空气接触的释热片 601， 也可以是导热管 604， 或 者两者都有。 导热管是一种通过某介 (水或其他液态流动介质 )可以将热量快 速传导到空气中的装置。导热管一端设置在最接近发光晶片的位置或直 发 光晶片封^^导热管上， 另一端有与空气充分接触的散热片， 以便将热量
到空气中如图 5所示。
所述的灯座体上围绕每一个大功率 LED灯芯设置有连接大功率 LED灯芯 正负电极 201的导电设施 3， 所述导电设施上连接有电源引出线 9， 所述电源 引出线穿 座体上的出线孔 4连接电源，所述出线孔带有密封胶圈或密封胶 5。 为使大功率 LED灯芯稳定的连接电源， 本实施例在灯座体上围绕每一个大 功率 LED灯芯安装一个悍接 LED灯芯电极的导电设施。导电设施可以是印刷 电路板， 也可以是直接印刷或电镀在灯座体上的电路。 这个导电设施在通常情 况下是不可或缺的。 电源引线不直接连接在灯芯上， 当电源引线受到较大拉力 时， 能够保护 LED灯芯电极。 印刷电路板或电镀电路可以是围绕大功率 LED 灯芯的环形， 也可以是门字形， 将大功率 LED灯芯放在门字形的两脚之间。 为了防水， 导电设施设置在密封空间中， 所以， 当电源引出线穿:^丁座体上的 穿线孔与夕卜部的电源连接时， 穿线孔中用密封胶密封， 或者穿线孔的出口处用 才象股圈^ "闭， 防止水汽的；^。
所述大功率 LED灯芯的出光面上设有密封设施 1 , 所述密封设施上有供 大功率 LED灯芯出光的透光孔 103。导电设施是棵露的金属导线或焊点，为导 电设施远离水汽， 必须有效的密封， 使导电设施保持干燥和清洁。 因此本实施 例设置一个将导电设施密封的密封设施。本实施例所述的密封设施可以认为是 一个盖板， 而灯座体形成盒子形， 大功率 LED灯芯和导电设施盛放在其中。 作为盖板的密封设施和作为盒子的灯座体结合可以形成一个密封的空间。 由于 大功率 LED灯芯是安装在灯座体上， 也就是说在灯芯的背光面， 作为盖板的 密封设施则在 LED灯芯的出光面， 所以密封设施上还必须有透光孔。 当然， 密封实施可以是透明的， 这样就无需透光孔。 而本实施例中的密封实施是不透 明的， 因此， 透光孔是必要的。 为了密封， 在密封设施与灯座体之间需要设置 密封垫或密封圈 102, 在透光孔与 LED灯芯之间， 准确的说是 LED灯芯的发 光面与透光孔之间需要设置密封圏 101。 这两个位置的密封圈也可以由密封胶 代替。 在每个透光孔的周围还可以设置反光面， 或称为散光面。 因为大功率 LED灯发出的光过于集中，可以使用光学原理将集中的光散开。散光面利用凸 镜面或棱镜面散光。在每个 面的外围还可以设置透明的散光罩， 利用散光 罩的光学作用， 将灯芯的一个小点的光源变成较大点的光源。 为了防止水汽的 干扰， 在散光罩与灯芯配 it t镜之间最好也是密封的。 应当指出的是， 根据不 同的设计， 反光面 光罩可以设置在密封设施上， 也可以设置在灯座体上。
围绕每一个所述大功率 LED灯芯的外围周围设置有将大功率 LED灯芯的 出光面和背光面联通的供散热的一个以上通气孔 7。 通气孔可以设置在灯芯的 一侧， 也可以设置在灯芯的两侧或四周， 总之可以使灯芯背光面和出光面的空 气交流。 如前所述， 对于大功率 LED灯芯散热问题必须妥善解决。 就目前的 技术水平， 一个大功率 LED灯芯， 还不能完全代替一个灯泡照明， 需要多个 大功率 LED灯芯组合， 才能达到满意的照明效果。 因此， 组合是大功率 LED 灯芯必然结果。 而组合后的大功率 LED灯可能形成片状， 使灯芯的背光面和 出光面形成隔墙， 造成空气隔绝， 这对于散热十分不利。 为解决这一问题， 本 实施例在每一个大功率 LED灯芯的周围都设置了通气孔， 使灯芯的背光面和 出光面之间有空气的交流， 从而实现了良^：热。 根据不同的设计， 通气孔可 以在灯座体上， 也可以在密封设施上， 或者两者都有。
如前所述， LED灯只有组合才能获得满意的照明效果， 由于有即可独立 又可组合的优点， 本实施例有多种组合方式。
首先， 本实施例可以将一个灯芯、一个灯座体和一个密封实施结合成为一 个独立的单独形灯座体， 并在单独形灯座体上设置相互连接的设施， 例如连接 桥接子的卡槽、 阴阳^ 勾、 串联连接杆的孔 602或固定耳、 固定连接条的 螺丝孔等等， 设施的形式很多。 通tt接设置， 多个单独形灯座体可以连接成 条状， 片状发光单元等等。 而这些条状和片状发光单元就可以形成各种花式的 灯具。 灯座体的截面形状可以是圓形、 三角形、 正方形、 正六边形、 正八边形 等等。
也可以在一个灯座体上安排多个灯芯， 如图 6所示， 图中所示的是 5个一 排的连接。 灯座体作为一个连接件， 或称为 出件， 其他零件都安装在灯座体 上， 形成一个多灯芯的发光单元。 多个灯芯可以一字排开， 形成条状灯座体， 或者多个灯芯纵横排列， 形成片状矩形灯座体。
本实施例所述的密封设施也可以作为一个连接件， 如图 7所示， 图中所示 的是 5个一排的连接。 密封设施作为连接件， 可以看作是连在一起的盖， 本实 施例称为灯架体。 其他零件都安装在灯架体上， 形成一个多灯芯的发光单元。 多个灯芯可以一字排开， 形成条状灯架体， 或者多个灯芯纵横排列， 形成片状 矩形灯架体。
本实施例也可以将灯座体和灯架体均设计为联排， 如图 8所示， 图中所示 的是 5个一排的连接。 这时通气孔必须同时穿过灯座体和灯架体， 才能联通灯 芯的出光面和背光面， 形成良好的空气 l t。
在连体的灯座体上散热器可以是随灯芯而分立，也可以是组合在一起。上 述的发光单元， 不论是条状的发光单 是片状矩形发光单元， 都设有连接部 件， 例如连接桥接子的卡槽， 穿连接杆的孔等等， 可以方便的和其他发光单元 进行组合， 形成更大的发光单元。
不论是单个灯芯的发光单元，还是多个灯芯的条^^光单元或是片状矩形 发光单元， 都可以组合形成多种形式的灯具， 如图 9所示的是一个户外使用的 路灯灯具， 是多个竖排的条状发光单元放在类似灯笼的支架上形成的。 图 10 所示的是室内使用的盘形灯，发光单元连接在一个花型支架上， 形成漂亮的图 案。 图 11所示的则是独立发光单元形在花型支架上形成的盘形灯。 图 15所示 条状发光单元组合成的隧 i ^丁。 图 16所示片状矩形发光单t且合成的路灯。 图 17所示发光晶片直接封装在导热管上的条状汽车灯。
类似的组合方案还有许多， 总之， 通过本实施例的组合， 可以实现多种花 样的灯具。
实施例二：
本实施例是实施例一的改进， 是实施例一所述 LED灯的细化， 如图 4所 示。本实施例所述的大功率 LED灯芯的发光晶片直接封装在所述的灯座体上。
本实施例为了最大限度的减少热阻， 将 LED灯芯的发光晶片封装在灯座 体上， 发光晶片发出的热量直接流向灯座体上， 而灯座体与散热器为一体， 因 此可以 发光芯片直接连接在散热器上， 散热效率明显提高。 实施例三：
本实施例是实施例一的改进， 是实施例一所述透光孔的细化， 如图 13所 示。本实施例在环绕所述的透光孔周围设置反光面 10，环绕所述反光面设置带 有散光罩密封圏的散光罩安装槽，所述散光罩安装槽中安装有将每一个大功率 LED灯芯的配光透镜到散光罩之间空间密封的散光罩 11。
本实施例的目的是将一个较小的点光源， 变为一个较大的点光源。 大的点 光源比较符合人的习惯， 不至于对人眼产生刺激。 本实施例的反光面和散光罩 均设置在密封设施上，根据不同的设计， 面和散光罩还可以设置在灯座体 上。

如实施例所述本实施例中的灯座体和散热器实际为一体， 因此， 所述的卡 槽和组合孔即在灯座体上也在散热器上。 卡槽是一种连接桥接子的槽， 可以设 置在灯座体的四周边，便于通过桥接子与其他发光单元连接。组合孔是一个通 孔， 可以穿±且合杆。 所述的组合杆是一根长杆， 可以将多个独立的发光单元 穿在一起， 形成各种灯具。
由于是独立的灯座体， 因此， 其外形近似棱柱或桶状， 其截面形状除上述 的圓形、 正方形、 正六边形外可以是三角形、 正八边形等等。
实施例五：
本实施例是实施例四的改接，是实施例四所述灯座体的细化。本实施例所 述的单独形灯座体的背光面向背光面外方向延伸并分叉， 形成释热片 601。 本实施例实际是散热器的变化， 因为散热器和灯座体为一体，在实际观察 上是灯座体在背光面的向背光面外的延伸， 如图 2中箭头 B的方向所示。
本发明中所述的出光面（图 2中箭头 A的方向）和背光面是相对与灯芯 而言。
