LED光源的T5灯管
本申请要求于2023年06月15日在中国专利局提交的、申请号为202321526648.3、发明名称为“LED光源的T5灯管”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请属于照明技术领域，更具体地说，是涉及一种LED光源的T5灯管。
 背景技术
传统常用的日光灯管是T8、T5日光灯，其直径分别为1英寸（25.4mm）、5/8英寸（16mm），长度有60cm和120cm、150cm三种。从结构形态上来讲，有支架（含镇流器）+灯管单支型和灯盘（含镇流器）+灯管多支型。随着LED技术在照明领域的快速发展，传统的日光灯几乎都被LED灯管取代，且市场竞争异常激烈。
LED灯管与传统的日光灯在外型尺寸口径上都是一样。材质有半型铝型材配合半型塑料灯罩、全型塑料灯罩、玻璃灯罩等，根据市场需求作不同选择和配置。
相对于T8或者口径更大的LED灯管，T5 LED灯管的口径更细，但是LED灯管的长度并不会因为口径细而缩短，更细的口径会导致整个灯管的抗弯曲刚性强度严重降低，在长时间使用过程中会发热，从而灯管会出现弯曲变形的情况，严重影响灯管的使用寿命。
 技术问题
本申请实施例的目的在于提供一种LED光源的T5灯管，以解决现有技术中的T5灯管的在长时间使用并发热后，由于自身刚性强度不够，导致灯管出现弯曲变形，严重缩短灯管的使用寿命的技术问题。

为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。
请一并参阅图1至图3，现对本申请实施例提供的LED光源的T5灯管进行说明。所述LED光源的T5灯管，包括玻璃灯罩10、基座20、灯头30、灯板40和电源组件50。
基座20设置在玻璃灯罩10内壁面上，基座20的长度沿伸方向与玻璃灯罩10的长度沿伸方向一致；灯头30与玻璃灯罩10的端部连接；灯板40设置在玻璃灯罩10内，并与基座20限位连接；电源组件50设置在灯头30内，并分别与灯头30和灯板40导通连接。
例如，如图1至图3所示，玻璃灯罩10呈圆筒状结构，玻璃灯罩10和基座20均呈长条状结构，并且基座20的长度略短于玻璃灯罩10的长度，基座20通过粘合材料固定在玻璃灯罩10的内壁面上，由于基座20一般采用轻质金属制作而成，自身具有较好的抗弯曲强度，通过将基座20固定在玻璃灯罩10的内壁面上，能够增强玻璃灯罩10的刚性强度，使其更难发生弯曲变形。玻璃灯罩10为端部开口的中空结构，通过将灯头30设置在玻璃灯罩10的端部，能够防止外部的物件进入到玻璃灯罩10内。灯板40在工作过程中会产生大量的热量，通过将灯板40安装在基座20上，灯板40中部分的热量会传递到基座20上，同时还能够避免灯板40在玻璃灯罩10内随意晃动。电源组件50主要用于为灯板40提供电力。
本申请提供的LED光源的T5灯管，与现有技术相比，本申请中的LED光源的T5灯管通过将基座20设置在玻璃灯罩10的内壁面上，并且基座20的长度沿伸方向与玻璃灯罩10的长度沿伸方向一致，能够在玻璃灯罩10发生弯曲变形时提供强度支撑，避免玻璃灯罩10出现弯曲变形，延长灯管的使用寿命；同时，采用玻璃灯罩10作为灯管的外罩体，由于玻璃自身的热固性较好，从而灯管在长时间使用后不容易发生弯曲变形，进一步提升LED灯管自身的刚性强度，延长整个LED灯管的使用寿命。
在本申请的一个实施例中，请一并参阅图2和图3，基座20背离灯板40的一侧设有加固凸肋21，加固凸肋21沿着玻璃灯罩10的长度方向沿伸设置。
具体地，加固凸肋21也为长条状结构，加固凸肋21的长度沿伸方向与玻璃灯罩10的长度沿伸方向一致，通过将加固凸肋21凸设于基座20的外侧面上，能够增强基座20自身的抗弯曲强度，从而间接地增强玻璃灯罩10的抗弯曲强度，进一步延长灯光的使用寿命。
在本申请的一个实施例中，请一并参阅图2和图3，加固凸肋21的数量为多个，多个加固凸肋21沿基座20的宽度方向间隔设置，且相邻两加固凸肋21之间形成有涂胶槽22。
具体地，加固凸肋21的数量为4个，4个加固凸肋21的形状不完全相同，位于最外侧的两个加固凸肋21上设有与玻璃灯罩10内壁面形状相适配的倒角结构，4个加固凸肋21位于基座20背离灯板40的一侧，4个加固凸肋21与玻璃灯罩10内壁面形状相适配。4个加固凸肋21两两之间一共形成有3个涂胶槽22，涂胶槽22沿着玻璃灯罩10的长度方向沿伸设置，通过在基座20上内凹形成有涂胶槽22，能够提高基座20与涂胶之间的接触面积，从而增大基座20与玻璃灯罩10之间的粘合力，避免基座20与玻璃灯罩10之间发生脱离。
在本申请的一个实施例中，涂胶槽22内设有用于粘合玻璃灯罩10和基座20的涂胶层。
具体地，T5型号的玻璃灯罩10两端开口的口径有限，难以将基座20通过结构限位在玻璃灯罩10内，通过在玻璃灯罩10和基座20之间设有涂胶层，能够在组装前先将涂胶凸设在基座20的涂胶槽22上，接着将基座20伸入到玻璃灯罩10内，然后直接将基座20贴靠早玻璃灯罩10的内壁面上即可完成安装，提高组装效率。
进一步地，涂胶层自身具有一定的导热性和粘合性，能够将基座20固定在玻璃灯罩10内的同时还能将基座20中的热量进行疏导。通过在玻璃灯罩10与基座20之间设有涂胶层，能够有效地避免灯板40在工作过程中产生的热量长时间集中在基座20上，提高灯管内部的散热性能。
在本申请的一个实施例中，请一并参阅图3，基座20靠近灯板40的一侧设有安装槽23，安装槽23用于对灯板40进行限位。
具体地，整个安装槽23呈U形结构，安装槽23的长度和宽度与灯板40的长度和宽度相适配，安装槽23能够对灯板40宽度方向上的相对两侧进行限位。通过在基座20上设有安装槽23，能够有效地将灯板40限位在玻璃灯罩10的内部，从而避免灯板40在玻璃灯罩10内随意移动。
在本申请的一个实施例中，请一并参阅图3，安装槽23的内壁面上设有限位部24，限位部24用于防止灯板40朝着背离基座20的一侧与安装槽23脱离。
具体地，限位部24限位于灯板40背离加固凸肋21的一侧，安装槽23配合限位部24能够对灯板40宽度方向的相对两侧和厚度方向的相对两侧进行限位。通过在安装槽23上设有限位部24，能够更进一步地将灯板40限位在玻璃灯罩10的内部，灯板40无法从自身宽度方向的方向与基座20脱离，也无法从自身厚度方向的方向与基座20脱离。
在本申请的一个实施例中，请一并参阅图1至图3，基座20采用铝型材制作而成。
具体地，铝型材具有较好的导热性能，并且相较于其他一些常用的金属，相同体积的前提下，铝型材的重量更轻。通过采用铝型材作为基座20，能够更高效地对灯板40产生的热量进行疏导，同时，相比其他一些常用的金属，还能使整个灯管更加地轻量化。
在本申请的一个实施例中，请一并参阅图2，电源组件50包括有电路板51和电器元件52，电器元件52设置在电路板51上，并与电路板51导通连接，电路板51上贴设有用于散热的导热片53。
具体地，电器元件52设置在电路板51的其中一侧，其中，电器元件52的数量有多个，多个电器元件52高度集中地设置电路板51上，并且每个电器元件52在工作过程中都会产生热量，电路板51在工作过程中也会产生大量的热量，电路板51上会积聚有自身的热量和多个电器元件52中的热量。导热片53采用高导热材料制成，能够高效地吸收附近的热量，及时对周围的高温物件进行热量的疏导。通过在电路板51上贴设有导热片53，能够避免电路板51在长时间的运行后，出现温度过高的问题，延缓电源组件50的老化进程，进一步延长LED光源的T5灯管的使用寿命。
在本申请的一个实施例中，玻璃灯罩10的外周侧面包覆有用于防止碎裂的保护膜。
具体地，保护膜主要的作用是避免玻璃灯罩10碎裂后产生的碎片向四周随意散落，保护膜具备高强度的粘结力、抗张力、160%高伸张度、强抗酸、抗碱性，在高温下也能保持物理性质的良好状态。同时又保持良好的透光率，在防爆的前提下还能保证灯管内部光线的穿透。玻璃防爆性能主要通过两个方面来实现：第一：充分利用保护膜上的粘胶层，将冲击力在表面分解。即使玻璃破碎，膜中粘胶层的胶质共同作用牵拉住玻璃碎片，防止飞溅，有效保护人身及财产安全。第二：通过保护膜独有的叠层间相互滑动的微位移，缓解穿过玻璃作用到安全膜的冲击力，形成独特的抗撞击性，有效的阻止因外力撞击所导致的玻璃破碎伤人。通过在玻璃灯罩10外设有保护膜，能够有效提高整个LED灯管的安全性能。
在本申请的一个实施例中，请一并参阅图2，灯头30上凸设有定位部31，定位部31用于对玻璃灯罩10的端部进行定位。
具体地，灯头30内具有容置腔，电源组件50设置在容置腔内，在组装的时候，先将电源组件50与灯板40导通连接，接着将灯板40伸入玻璃灯罩10并限位在基座20上，此时电源组件50外露预玻璃灯罩10的其中一端，最后将灯头30套设在电源组件50的外周侧，并将灯头30与玻璃灯罩10相互卡合限位在一起。通过在灯头30的内壁面上设有定位部31，能够避免灯头30与玻璃灯罩10之间的卡合位置与预设的位置出现偏差，从而导致整个LED灯管的尺寸出现偏差。
以上仅为本申请的较佳实施例而已，仅具体描述了本申请的技术原理，这些描述只是为了解释本申请的原理，不能以任何方式解释为对本申请保护范围的限制。基于此处解释，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进，及本领域的技术人员不需要付出创造性的劳动即可联想到本申请的其他具体实施方式，均应包含在本申请的保护范围之内。
