Description

一体化LED节能灯 技术领域
本发明涉及一种节能灯式的LED产品，具体的说是一种采用导热胶及光扩散剂的一体化LED节能灯。
背景技术
目前节能灯主要是采用PC塑料灯管或玻璃灯管，其中灯管内或者灯管外喷涂有光扩散剂，带LED灯珠的直条形的铝基板直接放置在塑料灯管或玻璃灯管内，如图6中的直条形铝基板；节能灯内部的铝基板与灯管内部存在间隙，这将导致铝基板不能得到良好的散热，导热效果差且功率较少，不能替换较大功率的传统节能灯。
发明内容
本发明的目的是提供一种一体化LED节能灯，解决如何使灯能得到充分的散热及良好的光扩散的技术问题。
一体化LED节能灯，包括灯管组、铝基板或环氧板或软灯条、LED灯珠、导热胶；所述灯管组包括一个以上的灯管，上述灯管为玻璃灯管，上述灯管内或者灯管外喷涂有荧光粉层；铝基板或环氧板或软灯条固定在灯管内部并与玻璃灯管内壁存在间隙，在上述间隙内填充有固态的导热胶；LED灯珠固定在铝基板或环氧板或软灯条上；上述灯管、导热胶、铝基板或环氧板或软灯条连接成一体。
所述灯管为“π”形。
所述灯管为“H”形。
所述灯管为“U”形。
所述灯管组具有2-20个灯管。
所述铝基板或环氧板成“H”形，包括左右两端；灯管为“π”形或者“H”形或者“U”形，铝基板或环氧板的左右两端均处于上述灯管内。
一体化LED节能灯，包括灯管组、铝基板或环氧板或软灯条、LED灯珠、导热胶；所述灯管组包括至少一个灯管，上述灯管为玻璃灯管，上述灯管内或者灯管外喷涂有荧光粉层，如荧光粉涂层；铝基板或环氧板或软灯条固定在灯管内部并形成“B”形或者“W”形空腔，在“B”形或者“W”形空腔内填充有固态的导热胶；LED灯珠固定在铝基板或环氧板或软灯条上，上述灯管、导热胶、铝基板或环氧板或软灯条连接成一体。
所述铝基板或环氧板成“H”形，包括左右两端；灯管为“π”形或者“H”形或者“U”形，铝基板或环氧板的左右两端均处于上述灯管内。
本发明的有益效果是：由于灯管为内或外喷涂有粉涂层的玻璃灯管，这样利用玻璃管通透性好的特性，灯管能较好的发射光，其中粉涂层如荧光粉层有利于光的扩散和传播；由于铝基板或环氧板设计成“H”形，可以节省每块铝基板或者环氧板间连接的电子线，实现装配工艺简化，可使每块基板上所贴LED色温一致性更好，降低因焊线所带来的诸多焊接不良因素；另外，另外一种模式的灯具采用铝基板或者环氧板固定在灯管内部并形成“B”形或者“W”形空腔，并在该空腔内填充有导热胶，这样增加铝基板或环氧板与导热胶的接触面积，这样使灯管得到充分的散热；通过增加软灯条，提高整个灯具的实用性和多选性。
