Description
技术领域
本实用新型涉及照明灯具领域，尤其涉及一种LED作为光源的灯泡。
背景技术
能源短缺是当今世界的热门话题，在照明行业中，LED灯泡因为它的高效、节能、环保、长寿命等多种优点，是取代能耗高，寿命短的传统白炽灯(钨丝灯)的首选。白炽灯(钨丝灯)包括灯丝，支架，透明灯罩，填充气体和灯头构成，支架支撑灯丝，透明泡壳内充入惰性气体，并要求密封，靠灯丝发热产生光，其效率低，工艺复杂，其好处是360度发光。目前市场上类似于白炽灯接近360度发光的LED灯泡也有，其结构包括灯头、灯壳和LED光源，灯壳上设置圆柱形或方形的支架，多个LED光源环绕安装在支架的外侧壁上，即除了靠近灯体一侧外其它五面均安装LED光源实现LED灯的360度发光，支架一般是采用铝基板，其存在的不足是光的利用率低，结构单一并且生产成本高。
发明内容
本实用新型的目的是为了克服现有LED灯泡存在的光的利用率低、生产成本高的问题，提供一种结构新颖，光的利用率高，生产成本低的LED灯泡。
为了实现上述发明目的，本实用新型采用了以下的技术方案：
LED灯泡，包括灯头、灯壳、灯罩和LED光源，灯壳安装在灯头上，灯罩安装在灯壳上，还包括用于支撑LED光源的导线，导线连接灯头，LED光源处于灯罩的内腔内；所述LED光源包括芯片、荧光粉和柔性PCB板，荧光粉涂在芯片上，芯片固定在柔性PCB板上，导线焊接在柔性PCB板上。
作为优选，所述柔性PCB板是印刷有电路的聚酰亚胺或聚酯薄膜板，生产 成本低，并且耐温效果好，尤其是长时间使用后也不会发黑变色影响发光的效率。
作为优选，所述柔性PCB板呈透明或半透明状，芯片360度发光都会穿过柔性PCB板，光可以任意透射而不会被挡住，光的利用率提高了一倍以上。
作为优选，所述导线通过锡焊接在柔性PCB板的电路上并在焊接处覆盖粘接剂固定；所述芯片通过绝缘胶、银胶或锡膏中的一种粘接在柔性PCB板上，芯片通过金线连接柔性PCB板。导线除了连通电源之外还起支撑LED光源的作用，因此上述固定方式可以将LED光源牢固的固定，延长使用寿命。
作为优选，所述LED光源直径在1.5mm之内，便于LED光源折弯或通过导线连成各种形状，直径太粗难以实现并且直径大重量就重不利于导线支撑。
作为优选，所述柔性PCB板折弯呈弧形且不能折角，折弯呈弧形便于制成各种形状，提高发光效率，折角后柔性PCB及其上的芯片以及连接芯片与PCB的金线就容易断裂损坏，不能使用。
作为优选，所述芯片的上下面或四周分别涂有荧光粉，荧光粉调节芯片发出的光的颜色，实现芯片全部发光即360度发光。
作为优选，所述柔性PCB板呈一字形，其上设置多块芯片；所述LED光源是多个，每个LED光源功率不超过1W，由于采用了柔性PCB板，因此不再使用铝基板支架等散热部件，因此工作功率不能太高，否则散热存在问题。
作为优选，所述LED光源是处于灯罩内腔的中心处，明显区别于目前一些LED光源安装在灯壳底面不处于灯罩的内腔内的结构，提高了发光效率。
作为优选，LED灯泡还包括支撑LED光源的支架，支架固定在灯壳上，当LED光源数量较多，尤其是出现多个LED光源共用导线的时候通过支架另外支撑LED光源稳定性更好。
按上述技术方案设计的LED灯泡，其优点是使用柔性PCB板结构新颖，不需要使用传统的铝基板或支架等散热结构，生产成本大大降低。综上所述，该LED灯泡的优点是结构新颖，光的利用率高，生产成本低。
附图说明
图1：本实用新型实施例1的结构示意图。
图2：本实用新型实施例2的结构示意图。
图3：本实用新型LED光源的结构示意图。
图4：图3的侧面局部放大结构示意图。
具体实施方式
下面结合附图1、图2、图3和图4本实用新型做进一步描述。
实施例1
如图1、图3和图4所示的LED灯泡，包括灯头8、灯壳9、至少2根导线2、灯罩11和多个LED光源10，灯壳9安装在灯头8上，灯罩11安装在灯壳9上，导线2连接灯头8，导线2即用于LED光源10和灯头8的连接同时起支撑LED光源10的作用。2根导线2之间的LED光源10处于灯罩11的内腔内，LED光源10最佳的位置是处于灯罩11内腔的中心处，发光效率高。
LED光源由芯片4、绝缘胶3、荧光粉7、金线6、导线2、粘接剂5和柔性PCB板1构成。荧光粉7涂在芯片4上，具体是芯片4的上下面或者其四周分别涂布荧光粉4，荧光粉4调节芯片4发出的光的颜色，实现芯片4全部发光即360度发光。芯片4固定在柔性PCB板1上并通过绝缘胶3粘接封装，绝缘胶3是环氧树脂胶。芯片4的电极通过金线6连接柔性PCB板1上的电路。柔性PCB板1呈透明或半透明状，柔性PCB板1是在聚酰亚胺或聚酯薄膜基板上印刷电路制作而成，生产成本低，并且耐温效果好，尤其是长时间使用后柔性 PCB板1也不会发黑变色影响发光的效率。柔性PCB板1的耐温范围在-45℃-300℃之间，配合芯片4的工作温度区间，达不到上述耐温效果的柔性PCB板1不适合使用。每个LED光源功率不超过1W，由于采用了柔性PCB板1，因此不再使用铝基板支架等散热部件，因此工作功率不能太高，否则散热存在问题。每块柔性PCB板1上规则设置多块芯片4，发光效率更高。2根导线2通过锡焊接在柔性PCB板的电路上并在焊接处覆盖粘接剂5固定。LED光源10直径在1.5mm之内，便于LED光源10折弯或通过导线2连成各种形状，直径太粗难以实现并且直径大重量就重不利于导线2支撑。
柔性PCB板1呈一字形即LED光源10呈一字形，便于2根导线2稳固的支撑，柔性PCB板1上设置多块芯片4，有助于提高发光效率。相邻两个LED光源10通过导线2连接构成V形，与传统的白炽灯的外观形状相同。芯片4的工作电压是在1.5V-240V之间，最为普及方便使用。
实施例2
如图2、图3和图4所示的LED灯泡，除柔性PCB板1形状和LED光源10排列形状外，LED光源10的数量可以是单个或多个，其它结构与实施例1相同。
柔性PCB板1折弯呈弧形，即LED光源10折弯呈弧形，便于制成各种形状，提高发光效率，相对于实施例1相邻两个LED光源10排成V形的结构LED光源10使用数量可以降低，柔性PCB板1可以折弯呈弧形但是不能折角使用，折角后柔性PCB上1的芯片4就容易翘起引起金线6断裂同时柔性PCB板1也容易断裂。
上述2个实施例仅为本专利的较佳实施方式，例如柔性PCB板1可以是透明或半透明状，也可以是不透明的，采用不透明的柔性PCB板1发光效率低于 采用透明或半透明状柔性PCB板1的LED灯泡，当使用不透明的柔性PCB板1时芯片4只需在上面涂荧光粉4即可，无需上下面或者其四周分别涂布荧光粉4，以节约材料降低生产成本；LED灯泡还可以包括支撑LED光源10的支架12，支架12固定在灯壳9上，当LED光源10数量较多，尤其是出现多个LED光源10共用导线2的时候通过支架12另外支撑LED光源10稳定性更好；芯片4可以是一排也可以是纵向排列的多排；芯片4也可以通过银胶或锡中的一种粘接在柔性PCB板1上，绝缘胶3也可以采用硅胶；柔性PCB板1的透明材料可以是有机或无机材料。
