—些缺点。 一、 能耗较大， 普通日光灯的能耗相当于 LED灯的四倍； 二、 不环保， 因为普通日光灯里面都含有水银， 会造成污染； 三、 危 险， 普通的日光灯使用的是 220V的交流电， 220V的高电压可以对 人体造成伤害； 四、 寿命短， 超低的寿命使灯具维护频繁。
当前也有一些使用 LED灯管类的产品， 但是这些产品通常都是 使用硬性灯条， 硬性灯条和灯管内壁的弧形不能很好的紧密的匹配， 无法实现良好的散热效果。通常的解决方法是， 在生产过程中用糊状 的导热胶做粘结剂将硬性灯条和灯管内壁连接起来， 这种生产过.程.， 出胶量不能精确控制，使得经常会有些地方用胶量多有些用胶量少影 响产品的品质， 及生产上的不可控次品率会比较高， 产量比较低。 同 时硬灯条上的 led光源， 由于光源和光源间有间隔， 硬性灯条和灯管 内壁之间是空心的， 所以普通 LED灯管在发光的时候， 光线会直射 到硬性灯条和灯管之间的结合处，所以在灯管背部就会有明显的一块 黑一块亮暗影， 从而影响产品的整体效杲，硬灯条使用的铝基板成本 较高。 发明内容

在一些实施方式中， 玻璃灯管的内壁上涂有光扩散剂涂层， 光扩 散剂涂层的材料为有机硅材质的纳米微珠。 其有益效果是， 这_种光扩 散剂其实质本身为一种白色粉末状物体，是一种细微的透明球体的形 状。 光线在穿过这些透明球体的时候， 会发生折射现象， 改变光的行 进路线， 达到匀光而又透光的目的， 使得发出来的光线更加的柔和， 同时还可以满足雾度值和透光率的需求
在 些实施方式中， 软性基.板是.厚度为 0.3mm至 0,6mm的铝基 板。 其有益效果是， 采用这.种厚度的超薄铝板既可以保护本发明对基 板为软性的要求， 同时， 相对于常规的硬质铝基板， 可以大大降低铝 的使用， 可以大大降低成本。
在一些实施方式中，软性基板是以聚酰亚胺或聚酯薄膜为基材的 柔性线路板 其有益效果是， 柔性线路板具有很好的可挠性， 方便与 玻璃灯管的内侧壁相吻合， 同时也方便电路的配置， 方便 LED灯珠 的安装。 在一些实施方式中， 导热粘结层为导热硅胶层。 其有益效果是， 导热硅胶层可以很好的将软性基板与玻璃灯管的内侧壁粘结在一起。

为了使得发光效果更好，可以在玻璃灯管 100的内壁上涂有光扩 这种光 -歉剂其实质本身为一种白色 4分 史物体 是"^种细微的透明 球体的形状 光线在穿过这些透明球体的时候， 会发生折射现象， 改 变光的行进路线， 达到匀光而又透光的目的，使得发出来的光线更加 的柔和， 同时还可以满足雾度值和透光率的需求。
对于本发明的软性基板 200的选捧可以有两种。一种是软性基板 200可以选用厚度为 0.3mm至 0.6mm的铝基板。 采用这种厚度的超 薄铝板既可以保护本发明对基板为软性的要求， 同时， 相对于常规的 硬质铝基板， 可以大大降低铝的使用， 可以大大降低成本。 另一种是 软性基板 200选用以聚酰亚胺或聚酯薄膜为基材的柔性线路板。柔性 线路板具有很好的可挠性， 方便与玻璃灯管 100的内侧壁相吻合， 同 时也方便电路的配置， 方便 LED灯珠 400的安装。
对于本发明的导热粘结层 300的选择也可以有两种。导热粘结层 300可以为导热硅胶层。 导热硅胶层可以很好的将软性基板 200与玻 璃灯管 100的内側壁粘结在一起。或者， 导热粘结层 300也可以为导 热双面胶层。 导热双面胶相对于普通的导热硅胶来说， 普通导热硅胶 实现粘结的时候， 需要等待导热硅胶千燥后才可以粘结牢固。 但是导 热双面胶在粘结时， 不需要等待千燥的时间， 只需要直接将软性基板
200与玻璃灯管 100的内侧壁直接进行粘结， 就可以直接实现稳固连 接 , 方便于批量生产时采用。
为了实现一个最大的发光角度。本发明中的软性基板. 200弯曲后 的曲面面积与玻璃灯管 100的侧壁面积的比例约为六分之一。 这样， LED灯珠 400发出的光线会直接照射在玻璃灯管 100其余六分之五 度做到最大。同时软' 基 ^ 200沿^^灯管 10^的内壁形成二个弧 形的区域， LED灯珠 400所发出的光经过软性基板. 200的反射， 有 效解决了 LED灯珠 400发光在玻璃灯管 100背部产生的阴影问题， 玻璃灯管 100 的背部表面看不到暗区， 不会出现明显的一块黑一块 亮，同时软性基板 200沿着玻璃灯管】00的内壁形成一个弧形的区域 并且二者是紧密连接的， 相互之间没有间隔空间， LED灯珠 400是 凹在弧形的软性基板 200内部， 所以 LED灯珠 400发出的光会经过 软性基板. 200的反射， 不会直接照射到软性基板 200与玻璃灯管 100 的结合处， 从而可以有效解决 LED灯珠 400发光在玻璃灯管 100背 部产生暗影的问题， 玻璃灯管 100的背部表面看不到暗区， 不会出现 明显的一块黑一块亮， 本发明的 LED 日光灯具具有与普通荧光灯相 同的发光效果， 并且结构更加的紧凑和简单。
以上的仅是本发明的一些实施方式。对于本领域的普通技术人员 来说， 在不脱离本发明创造构思的前提下，还可以做出若千变形和改 进， 这些都属于本发明的保护范围。
