Description

LED灯泡
本发明涉及一种LED照明灯具，特别是一种LED灯泡。
LED光源具有发光效率高、低发热、省电和寿命长的优点，因此其应用越来越广泛。LED灯将逐渐取代白炽灯和卤素灯等传统照明灯具。现有的LED灯大都是由泡壳、散热件、光源组件、驱动组件、灯头等组成，组装时需要将较多的元件分别组装，组装步骤较为复杂，且同时为了满足大角度发光的要求需要增设反光透镜等结构，出光效率大大的降低。常见的LED灯包括LED光源板和罩设在该LED光源板上方的灯泡壳。其通过球泡壳形状的灯泡壳对LED光源板上的LED光源发出的光线进行二次配光。由于灯泡壳有的部分距离LED光源较近，而有的部分距离LED光源较远，这一方面导致其在整个空间内难以实现均匀配光，另一方面导致其难以做到多种不同光束角分布的配光，配光灵活性不高。
有鉴于此，有必要提供一种便于配光的LED灯泡。
一种LED灯泡，包括LED光源板、灯头体及透光壳，该LED光源板为条形结构，该LED光源板上设有多个LED光源，该LED光源板的至少一端固定在该灯头体上，该LED光源板的中部远离该灯头体设置，该透光壳一体包覆该LED光源板上的LED光源，该透光壳用于折射所述LED光源发出的光线，并使所述LED光源发出的光线分布更均匀。
与现有技术相比，该LED灯泡设置有条形结构的LED光源板并使得该LED光源板的中部远离该灯头体设置，将该透光壳一体包覆在该LED光源板上的LED光源，这种结构使得该LED光源板上的LED光源能够朝向立体空间发光，由于该LED光源板的形状可以根据配光需求进行调整，使得LED光源与透光壳的出光面的距离较近，从而可根据需求进行配光，具有便于配光的优点。

图2
是图1所示LED灯泡的立体分解图。
图3

下面结合附图与具体实施方式对本发明作进一步详细描述。
本发明第一实施例的LED灯泡，请参考图1至图3，该LED灯泡，包括LED光源板10、灯头体20及透光壳30，该LED光源板10为条形结构，该LED光源板10上设有多个LED光源，该LED光源板10的至少一端固定在该灯头体20上。优选的，该透光壳30与该灯头体20一体成型，且该LED光源板10的两端均固定在该灯头体20上。
本实施例中，该LED光源板10的中部远离该灯头体20设置，该LED光源板10由柔性材料制成，该LED光源板10为弯折的条形结构，这些LED光源11设置于该LED光源板10的正面上。因此，该LED光源板10可以向立体空间发光，通过选择适当的形状，能够实现大角度发光或其他特定的光学分布。由于LED光源板10为柔性的，其可以弯折形成多种形状，除了图3所示的上大下小的环形结构外，还可以为方框结构、螺旋结构或其他弯折结构。LED光源板10的形状的不同必然导致最终的光学分布不同。
本实施例中，该透光壳30一体包覆该LED光源板10上的LED光源11，该透光壳30用于折射所述LED光源11发出的光线并使所述LED光源发出的光线分布更均匀，同时，该透光壳30还可扩大这些LED光源11发出的光线的分布角度。由于该透光壳30一体包覆该LED光源板10上所有的LED光源11，所以，这些LED光源11发出的光线将统一从该透光壳30的出光面射出，从而使光线分布更均匀。优选的，该透光壳30由导热材料制成，该透光壳30与这些LED光源11或该LED光源板10热连接，使得这些LED光源11所产生的热量能够快速被传递出去，提高整灯的散热效果。本实施例中，该透光壳30包覆该LED光源板10及这些LED光源11形成弯折的柱体结构。
优选的，还包括固定架40，该固定架40设有支撑架41，该支撑架41对应该LED光源板10设置成条形结构，该LED光源板10固定于该支撑架41上，该透光壳30一体包覆该支撑架41、该LED光源板10及这些LED光源。该支撑架41上对应该LED光源板10设有凹槽411，该凹槽411的侧壁上凸出设有挡柱412，这些挡柱412与该凹槽411的底面形成间隙，该LED光源板10穿过这些间隙并被这些挡柱412抵在该支撑架41的凹槽411内，这样可固定住该LED光源板10。该固定架40还设有定位部42，该支撑架41的底端连接于该定位部42上，该定位部42的底部开有定位槽421，该定位部42伸出该透光壳30之外。该固定架40采用与该透光壳30一样的透光导热材料制成。
其中，还包括驱动板50，该驱动板50固定在该定位槽421内，该灯头体20与该透光壳30一体注塑成型并包覆该定位部42及该驱动板50的至少一部分。优选的，该驱动板50可与该LED光源板10制作成一体结构。该灯头体20与该透光壳30采用一体注塑工艺包覆在该LED光源板10及该驱动板50的至少一部分上，简化了传统的装配工艺，无需将传统灯泡壳、光源板、散热件等分别装配，具有制造工艺简单、便于自动化生产的优点，且整灯结构简单、大大降低了制造成本。
此外，还包括灯头壳60，该灯头壳60与该灯头体20连接形成腔体70，该驱动板50的另一部分伸出该灯头体20并收容在该腔体70内，该驱动板50的另一部分连接有两个电极，这些电极与该灯头壳60电连接。
综上所述，该LED灯泡设置有条形结构的LED光源板10并使得该LED光源板10的中部远离该灯头体20设置，将该透光壳30一体包覆在该LED光源板10上，这种结构使得该LED光源板10上的LED光源11能够朝向立体空间发光，即可实现全周光大角度发光，具有整灯结构极为简单的优点。此外，LED光源11发出的光线无需像传统LED灯泡中那样需经空气与灯泡壳的反射界面，降低了界面反射，提高了透光性，使得整灯具有更高的光学效率。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明保护的范围之内。
