Description

LED灯
技术领域 本发明涉及一种 LED灯， 尤其是一种带有金属反光灯杯且 LED是以 拱形方式排列的 LED灯。
背景技术
LED (发光二极管）具有寿命长、光效高、无辐射、 抗冲击以及低功 耗等优点， 属于节能的绿色环保照明， 因此以 LED为光源的 LED灯也不 断涌现， 但现有的 LED灯的灯杯都是由玻璃或塑料制成的， 这两种材料制 成的灯散热效果都不是很好， 而且玻璃制成的灯杯增加了整个灯的重量， 用这些材料制成的灯杯对于 LED光源没有起到任何辅助作用； 另外， 目前 的 LED灯里面的 LED都是按照矩阵方式朝一个方向排列的，而且现有 LED 灯上的透明灯盖和 LED之间的距离很近， 不利于光的散射， 灯盖与杯体之 间都是用胶粘贴在一起的， 使用一段时间后， 胶体容易老化， 灯盖易脱落。
发 明 内 容 针对上述现有技术存在的不足， 本发明旨在提供一种采用金属反光灯 杯， 且以半球形方式排列 LED的 LED灯， 该灯具有光反射度强， 光量大， 光线角度宽等特点。
本发明的另一个目的是解决 LED灯的散热问题， 以便于有效地利用具 有高光通量的 LED。
本发明还有一个目的是解决 LED灯的灯盖与灯杯之间的连接问题。 为实现上述目的， 本发明包括： 灯盖、 金属灯杯、 连接灯帽和金属灯 杯的绝缘层以及金属灯杯里的 LED、 半球形托板或散光板、 PCB板（平面 印刷线路板）， 其特征在于： 所述的 PCB板上设有一个半球形的托板， 半 球形托板上有和 LED的个数相同的孔， LED就安装在半球形托板的孔中， LED的电源接头穿过半球形托板与 PCB板连接，接通电源。通过这种方式 安装的 LED是固定在半球形托板上的，并呈半球形排列的， LED的光源是 向不同方向射出去的， 增大了 LED灯发光的角度。 当半球形托板由透明或 半透明材料制成时,可将 LED芯片加工到半球形托板的内侧成半球形排列， 各 LED芯片通过电源引线串联， 电源引线再与 PCB板连接， 接通电源后 发光并通过透明半球开托板将光源射出去。
本发明的另一特征在于， 其采用了金属灯杯， 金属灯杯是由金属材料 制成的， 面积较大， 在金属灯杯的杯体里面有一层电镀的反光膜， 这层反 光膜可以是在制作金属灯杯时直接在其里层加工而成， 或者把一层制作好 的反光膜套粘在普通金属灯杯的里层，这样 LED所发射出来的光可以通过 金属灯杯里层的反光膜反射出去， 不但增加了亮度， 反射的光也更均匀， 同时金属的散热性很强， 采用金属灯杯有效的解决了 LED的散热问题。
本发明申请人于 2004 年 9 月 1 日申请的、 专利申请号为 200420093010.6、 名称为 "LED灯泡"的实用新型专利和 PCT申请中的散 光板同样可以运用在本发明中， 即 LED的外围有一个散光板， 该散光板由 透明或半透明材料如树脂等制成，散光板上有和 LED的个数相同的孔并与 LED加工成一体， 这样散光板和 LED结合成一个发光整体并与安装 LED 的 PCB板之间有距离， 散光板吸收 LED折射出来的光并从不同角度反射 出去， 采用这种方式后， 散光板与 LED结合成一个发光整体， 可以获得均 匀的照明， 同时解决了 LED灯光束集中、 角度窄的问题， 增大了 LED灯 发光的角度。
本发明还有一个特征在于， 所述灯盖由透明或半透明材料制成， 在灯 盖与金属灯杯的周边加工有螺孔，灯盖的螺孔与金属灯杯的螺孔互相对应， 并可通过螺丝将灯盖与金属灯杯紧密结合在一起， 不易脱落； 又由于金属 灯杯的面积较大， 灯盖与金属灯杯内呈半球形排列的 LED之间距离较远， LE 从不同方向放射出来的光经金属灯杯里层反光膜的大面积反射， 可以 获得更均匀、 更高效的光源。
本发明的特征还在于， 在金属灯杯和灯帽之间设有以塑胶或其它绝缘 材料制成的绝缘层， 以防止导电。 2 所述为灯帽可根据需要制成螺口或卡口。
采用本发明后， 由于采用了半球形排列的 LED或将 LED与一散光板 结合成一个发光整体， 同时使用了大面积的金属灯杯作为该灯的外壳， 获 得了更均匀更高效的光源， 同时解决了散热问题。
本发明的目的、 特征及优点将通过实施例结合附图进行详细说明。
附 图 说 明 图 1是本发明 LED灯实施例一的结构示意图；
图 2是本发明 LED灯实施例二的结构示意图；
图 3是本发明 LED与半球形托板结合方式实施例的示意图； 图 4是本发明 LED灯的灯盖与金属灯杯的连接方式的示意图。
图中： 1、 灯盖； 2、 金属灯杯； 3、 LED; 4、 半球形托板； 5、 PCB板； 6、 绝缘层； 7、 灯帽； 8、 散光板； 11、 螺丝； 12、 螺帽； 21、 反光膜； 31、 电源接头； 32、 LED芯片； 33、 电源引线。
具体实施 方式 参照图 1， 本发明 LED灯包括： 灯盖 1、金属灯杯 2、连接灯帽 7和金 属灯杯 2的绝缘层 6以及金属灯杯里的 LED3、 半球形托板 4、 PCB板 5， 其特征在于： 所述 PCB板 5上设有一个半球形托板 4， 半球形托板 4上有 和 LED3的个数相同的孔， LED3就安装在半球形托板 4的孔中， LED的 电源接头 31穿过半球形托板 4与 PCB板 5连接，通过这种方式安装的 LED3 是固定在半球形托板上的，并呈半球形排列的， LED3的光源是向不同方向 射出去的， 增大了 LED灯发光的角度。
图 3是本发明的 LED灯的 LED3与半球形托板 4结合方式的实施例的 示意图， 如图 3b所示， 当半球形托板由透明或半透明材料制成时， 可直接 将 LED芯片 32加工到半球形托板 4的内侧， 成半球形排列， 各 LED芯片 32通过电源引线 33串联， 电源引线 33再与 PCB板 5连接，接通电源后发 光并通过透明半球开托板将光源射出去。
图 2为本发明的另一个实施例， 包括： 灯盖 1、 金属灯杯 2、 连接灯帽
7和金属灯杯 2的绝缘层 6以及金属灯杯里的 LED3、散光板 8、 PCB板 5， LED3的外围有一个散光板 8， 该散光板 8由透明或半透明材料如树脂等制 成， 散光板 8上有和 LED3的个数相同的孔并与 LED3加工成一体， 这样 散光板 8和 LED3结合成一个发光整体并与安装 LED3的 PCB板 5之间有 距离， LED3下端的电源接头 31与 PCB板 5连接， 散光板 8吸收 LED3折 射出来的光并从不同角度反射出去， 采用这种方式后， 散光板 8与 LED3 结合成一个发光整体，可以获得均匀的照明，同时解决了 LED灯光束集中、 角度窄的问题， 增大了 LED灯发光的角度。
参照图 4， 本发明 LED灯采用了金属灯杯 2， 所述的金属灯杯 2是由 金属材料制成的， 面积较大， 在金属灯杯 2的杯体里层有一层电镀的反光 膜 21，这层反光膜 21可以是在制作金属灯杯时直接在其里层加工而成，或 者把一层制作好的反光膜套粘在普通金属灯杯的里层， 这样 LED3所发射 出来的光可以通过金属灯杯里层的反光膜反射出去， 不但增加了亮度， 反 射的光也更均匀，同时金属的散热性很强，采用金属灯杯有效的解决了 LED 的散热问题。
如图 4所示的 LED灯， 所述灯盖 1由透明或半透明材料制成， 在灯盖 1和金属灯杯 2相结合的周边加工有螺孔，灯盖 1的螺孔与金属灯杯 2的螺 孔互相对应， 并可通过螺丝 11和螺帽 12将灯盖 1与金属灯杯 2紧密结合 在一起， 不易脱落； 又由于金属灯杯 2的面积较大， 灯盖 1与金属灯杯 2 内呈半球形排列的 LED3之间距离较远， LED3从不同方向放射出来的光经 金属灯杯 2里层反光膜 21的大面积反射，可以获得更均勾、更高效的光源。
本发明的特征还在于， 在金属灯杯 2和灯帽 7之间设有以塑胶或其它 绝缘材料制成的绝缘层 6， .以防止导电。
所述为灯帽 7可根据需要制成螺口或卡口。
上述本发明结构和材料要求都有非常简单， 易于大规模生产， 前景广 阔。
显然， 上述实施例仅供说明本发明之用， 而并非对本发明的限制。 有 关技术领域的普通技术人员根据本发明在相应的技术领域做出的变化应 于本发明的保护范畴。
