Description

护眼格栅灯
技术领域
本发明涉及一种格栅灯， 具体涉及一种加工组装便捷， 可有效提高光效和防止眩 光的护眼高光效格栅灯。 背景技术
直管荧光灯有着悠久的使用历史， 自 1984年北美照明工程协会提出眩光及灯具 防眩光的概念， 直管荧光格栅灯即迅速成为在室内场所应用最为广泛的灯具之一。
目前市场上的格栅灯， 所使用的格栅绝大部分采用的形式为格栅边花、格栅头花 与格栅片相互连接组装而成。 其组装过程过于繁杂， 消耗大量人力成本， 对于零件加 工的配合要求也很高， 这样就造成生产效率低下和生产成本的提高。 此外， 由格栅边 花充当反射器， 只能将灯管两侧射出的光线部分反射利用， 提高光效， 却无法反射灯 管背面射出的光线。 也有部分格栅灯采用注塑成型的网格状格栅， 覆反射膜。 这种格 栅灯虽然加工组装过程便捷性有所提高，但损失的光效更多， 同时在防眩光方面的作 用也有所降低。 发明内容
本发明的目的就是针对现有的格栅灯存在的上述不足进行改进，提供一种加工安 装便捷， 光效高且防眩光效果好的护眼高光效格栅灯。
本发明的技术方案如下：
一种格栅灯， 包括灯盘， 格栅片、 反射器、 荧光灯座和荧光灯管， 所述反射器平 行于所述荧光灯管而设置， 所述格栅片垂直于所述荧光灯管而设置， 其特征在于， 所 述格栅片形成独立于所述反射器的一体化的格栅板，即所述格栅板与所述反射器互相 分离， 所述格栅板直接可拆卸地连接在灯盘上。
其中， 所述格栅板通过挂钩与挂扣扣合在所述灯盘上， 并且所述格栅板可以从所 述灯盘松脱而打开。
其中， 所述反射器被固定在所述灯盘上， 所述反射器包覆所迷荧光灯管的背面与 两个侧面， 从而将所述荧光灯管的射出光反射到前方。 确认本 其中， 所述格栅板包括至少两列格栅片， 每列格栅片与一个荧光灯管相对应； 每 个格栅片的外形轮廓与相应反射器的内侧面轮廓相适合， 从而当扣合所述格栅板时， 每个格栅片可以嵌入所述反射器的内侧， 当打开所述格栅板时，每个格栅片可以从所 述反射器内部退出。
其中，相邻格栅片的间距略大于或等于格栅片的最大高度，使得遮光角 α在 30 ° ≤ α ^ 45°的范围内。
实施本发明的护眼高光效格栅灯，由于其格栅片形成了独立于反射器的一体化的 格栅板， 因此， 结构合理简单， 整体性好， 生产制造、 加工組装便捷。 由于反射器包 覆所述荧光灯管的背面与两个侧面，因此，可以反射灯管射向灯体内的几乎所有光线， 极大地提高了光效。 由于格栅片密集排列， 形成的防眩光角可有效防止产生的眩光， 保护使用者的眼睛。 附图说明
以下结合附图与具体实施例对本发明进行进一步阐述。
图 1是本发明护眼高光效格栅灯的一个实施例的安装状态的立体结构示意图； 图 2是图 1所示的护眼高光效格栅灯的格栅板从灯盘打开后的立体结构示意图； 图 3是沿图 1的 A- Α线的剖面结构示意图；
图 4是沿图 1的 B- B线的剖面结构示意图；
图 5a是图 3所示的护眼高光效格栅灯的局部放大示意图， 其中采用类抛物线形 反射器；
图 5b是本发明护眼高光效格栅灯的另一个实施例的局部放大示意图， 其中采用 圆弧形反射器；
图 5c是传统格栅灯中的反射器结构示意图。
图中： 1灯盘、 2格栅板、 3反射器、 4荧光灯管、 5荧光灯座、 6电子镇流器、 7 接线柱、 8挂钩、 9挂扣、 格栅盘 21、 格栅片 22。 具体实施方式
如图 1、 图 2和图 3所示， 本发明的一个实施例为使用三根 T5荧光灯管的嵌入 式护眼高光效格栅灯。 所示三灯管嵌入式护眼高光效格栅灯包括： 灯盘 1、 格栅板 2、 反射器 3、 荧光 灯管 4、 荧光灯座 5、 电子镇流器 6、 接线柱 7、 挂钩 8、 挂扣 9 , 以及相应的安装结 构与布线结构。
三对荧光灯座 5分别固定于灯盘 1端面预设的灯座安装孔内，荧光灯管 4两端分 别插入灯盘 1两端固定的荧光灯座 5。三只反射器 3通过螺钉固定于灯盘 1的底板上， 每只反射器 3对应一只荧光灯管 4，三只荧光灯管 4分别设置在三只反射器 3的前方， 每只反射器 3包覆相应荧光灯管 4的背面与两侧面，从而将荧光灯管 4的射向其背面 与两侧面的光反射到前方。 电子镇流器 6、 接线柱 7安装于灯盘 1底板内侧。
格栅板 2为一体化的矩形体， 与反射器 3可相互分离。格栅板 2包括有三列格栅 片 22 ,每列格栅片对应一根荧光灯管 4与一只反射器 3。在格栅板 2的相邻两列格栅 片之间为格栅盘 21 , 格栅盘 21起连接和支撑的作用， 格栅盘 21的区域上还可以印 制有网孔装饰图纹。
格栅板 2由整块钢板或铝板或其他金属板材通过冲裁、 冲压、折弯等工序直接成 型， 省去了格栅装配工序。 成型后表面进行喷涂或电镀处理， 使其表面具有较高的光 反射性。 由于冲压过程中使用机械化生产， 保证了工艺稳定性， 避免了人工操作所造 成的灯具格栅装配精度的降低。冲压成型的格栅片外形轮廓可以很方便的加工成圓弧 形或抛物线形， 在增强美观性的同时可以更方便的契合反射器弧度。
格栅板 2的一侧直接通过挂钩 8挂扣并固定于格栅灯盘 1侧边的钩槽内，另一侧 通过活动挂扣 9可拆卸地挂扣在灯盘 1的相对侧边上。 挂钩 8垾接于格栅 2板一侧， 挂扣 9通过铆钉铆接于格栅板 2另一侧。 安装格栅板 2时， 先将挂钩 8挂于灯盘 1 一侧的鈎槽内， 再将格栅板 2托起， 合上挂扣 9以将格栅板 2完全固定； 进行更换镇 流器 6或荧光灯管 4等维修操作时， 松开挂扣 9 , 格栅板 2便可通过挂扣 8悬挂于灯 盘 1上（如图 2所示）， 具有更高的操作便捷性与操作安全性。
相对传统格栅应用簧片、 簧丝的安装方式， 应用挂扣与挂钩组合安装， 具有更好 的安装便捷性与稳定性， 且不会在安装过程中对人体造成刮伤、 划伤， 更为安全。 如图 5a所示， 本实施例所应用的反射器 3 , 其内表面轮廓为多段不同圆弧与直 线段衔接而成的近似于抛物线形状； 每片格栅片 22的外形轮廓与相应反射器 3的内 侧面轮廓相适合， 且格栅片 22的侧边与反射器 3内壁留有细小间隙， 从而当扣合格 栅板 2时， 每列格栅片 22可以嵌入相应反射器 3的内侧， 当打开格栅板 2时， 每列 格栅片 22可以从所述反射器内部容易地退出。
其中， 格栅片 22的靠近荧光灯管 4的边缘是可以是内凹的圆弧型或直线或其他 与配光要求相适合的形状。
一般地，遮光角 α的正切 tg α为格栅片 22的高度与相邻格栅片之间距离的比值， 在本发明中， 因格栅片 22的外形轮廓的上侧呈内弧形， 于其中点处的高度最低， 所 形成的遮光角角度为最小值。 如图 4所示， 在本实施例中， 测得其在格栅片 22的中 点处的最小遮光角约为 35° , 即在本实施例中， 格栅片 22的整体遮光角不小于 35°。 在本发明中，格栅片呈密集排列， 则相邻格栅片之间的间距最小可等于单个格栅片的 最大高度， 即其遮光角 ex最大可达 45。。 根据灯具配光要求与生产工艺的要求， 本发 明的遮光角 α—般取值 30 ~ 42°。 根据《建筑照明设计标准》， 格栅灯具有较高防眩 光要求时 UGR 19 , 其遮光角 α要求不小于 25°。 由此可见， 应用本发明的格栅灯具， 其防眩光性能远远高于一般室内格栅灯具的防眩光要求。 本实施例所应用的反射器 3由高光反射性铝板滚压成型，通过螺釘或铆钉直接固 定在灯盘 1的底板上， 并包覆荧光灯管 4的背面与侧面， 可以反射荧光灯管 4射向灯 具内部的几乎所有光线。
如图 5b所示， 在另一个实施例中， 反射器 3的内表面轮廓也可以是圆弧型， 由 具有高光反射性的镜面板或漫反射亚光板制成， 通过螺钉或铆钉直接固定在灯盘 1 的底板上， 并包覆荧光灯管 4的背面与侧面。
如图 5c所示， 传统格栅灯应用格栅边花作为反射器， 仅能反射荧光灯管射向其 两侧面的光线， 无法反射荧光灯管射向其背面的光线， 相比之下， 应用本发明的格栅 灯具明显具有更高的光学效率。 本发明的实施例中所阐述的格栅灯为嵌入式安装的格栅灯，但是， 本发明同样适 用于吸顶式安装或悬挂式安装的格栅灯。
