Description

一种LED台灯 技术领域
本发明属于照明器材，特别涉及一种具有保护视力作用的LED灯。
背景技术
灯具是人们日常生活和学习中最常见的家用电器之一，最常用的是白炽灯。然而随着人们对于资源的节约、环保的重视，LED灯作为新的照明设备越来越广泛地为人们所接受。LED灯是一种绿色光源，具有节能、环保、安全可靠的特点，已经普遍应用于家庭、工作照明中。
人们目前所使用的LED灯，仅仅是以LED灯珠作为光源，没有对其进行过仔细研究，导致了LED灯仅仅是照明作用。
后来人们发现，普通日光灯发光时产生每秒100次的周期性明暗闪烁，这种波动就是低频闪；LED灯则是高频闪，将灯管的亮灭闪烁加快到每秒几千次甚至几万次，超过人眼的神经反应速度，使眼睛感觉不到灯光的频闪变化，因此对眼睛起到一定的保护作用。因此，人们开始普遍采用LED灯作为工作、生活的照明灯具。
如专利申请201020618879.3公开了一种多功能LED护眼灯，实际上就是一种台灯，其包括扩散板、导光板、芯片式LED发光模组、环形外框和一镜面，所述环形外框的内环壁上设有一道环形槽，环形槽内设有一卡装导轨，所述芯片式LED发光模组限位于卡装导轨内，所述扩散板、导光板和镜面设于环形槽内，构成一面镜子一面照明灯的结合体。该实用新型采用芯片式LED侧光照明，将LED模条绕导光板和扩散板环绕设计，使得亮度更高，具有使用寿命长、节能环保的优点。然而该LED灯结构复杂，制作成本高，且并在使用时LED灯的调节需要专门的技巧，不了解使用方法的人达不到护眼的效果， 因此护眼效果并不明显。
而且，更为重要的是上述的护眼灯并没有考虑到人们的使用习惯，因此，人们在使用时并不会学习最佳的利用方式，从而影响到LED护眼灯的使用效果。
发明内容
为解决上述问题，本发明的目的在于提供一种LED台灯，该LED护眼灯能够从合理的角度为人们提供照明，便于人们保护视力。
本发明的另一个目的在于提供一种LED台灯，该LED护眼灯结构简单，便于收拢，占用体积小，易于放置，便于办公及家庭使用。
为实现上述目的，本发明的技术方案如下。
一种LED台灯，其包括有底座、支架、LED灯组，其特征在于所述支架为“之”字形结构，支架与底座、LED灯组之间设置有限位机构，以控制支架、LED灯组的张开角度，保证为人们提供合理角度的照明，从而实现保护人们的视力的效果。
所述支架与底座的限位机构，为一护板；支架通过固定轴铰接于底座上，护板也同时铰接于底座上，且护板覆盖于支架外侧，并伸出于支架外，向底座进行适当延伸，在打开支架时，延伸的护板会抵触到底座，使支架打开到一定的角度后不能再继续打开，从而保证了支架打开的角度，由此限制LED灯组的角度，为人们提供合理角度的照明，同时也便于人们使用。
所述支架与LED灯组的限位机构，为两块盖板，其中一块盖板为上盖板，覆盖于LED灯组上，另一块盖板为下盖板，覆盖于支架上；支架通过连接轴铰接于LED灯组上，所述两块盖板也同时铰接于连接轴上，且上盖板覆盖于LED灯组上，并延伸于LED灯组外，向支架方向延伸；下盖板覆盖于支架外侧，并伸出于支架外，向LED灯组方向进行适当延伸，在打开LED灯组时，延伸的两块盖板会相互抵拢，使LED灯组打开到一定的角度后不能再继续打开，从而 保证了LED灯组打开的角度，为人们提供合理角度的照明，人们使用时不比调整角度就可以直接使用，使用更加方便。
所述支架为“之”字形结构，包括下支架和上支架，其中下支架铰接于底座的固定轴上，下支架和上支架通过铰轴连接在一起，上支架则通过连接轴连接并支撑LED灯组；所述下支架和上支架间还设置有限位机构，以控制下支架和上支架打开的角度。
进一步，所述的限位机构，为覆盖于下支架和上支架的限位板，其中，覆盖于上支架的限位板为上限位板，覆盖于下支架的限位板为下限位板；所述上限位板覆盖于上支架上，并延伸于上支架外，向下支架方向延伸；下限位板覆盖于下支架外侧，并伸出于下支架外，向上支架方向进行延伸，在打开支架时，延伸的两个限位板会相互抵拢，使支架打开到一定的角度后不能再继续打开，控制支架打开的角度，从而保证LED灯组照明的角度，人们使用时不比调整角度就可以直接使用，使用更加方便。
更进一步，所述下支架和上支架交错设置，所述下支架设置于上支架的外侧，并通过铰轴连接在一起，在收拢使，上支架能够收拢于下支架之间的空位内，以有效地减少收拢体积。
更进一步，所述LED灯组，其宽度小于上支架的间距，以在收拢时，能够收拢于上支架之间，既有保护LED灯组的作用，又能够减少收拢体积和空间，便于人们携带及使用。
本发明通过限位机构的设置，有效地控制支架及LED灯组的打开角度，从而能够为人们提供合理的照明角度，便于LED灯组发挥最有效的照明效果，以保护人们的视力。
而且，该LED护眼灯结构简单，便于收拢，占用体积小，易于放置，便于办公及家庭使用。

图2是本发明所实施的打开状态的左视图。
图3是本发明所实施的打开状态的仰视图。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
请参照图1、图2所示，本发明所实施的一种LED台灯，其主要包括有底座1、支架4和5、LED灯组3，所述支架4和5构成“之”字形结构，支架包括下支架5和上支架4，其中下支架5铰接于底座的固定轴51上，下支架5和上支架4通过铰轴41连接在一起，上支架4则通过连接轴31连接并支撑LED灯组3。
为了保证LED灯组3打开的角度适合照明，下支架5与底座1之间设有限位机构，上支架4与LED灯组3间设有限位机构，下支架5和上支架4之间也设有限位机构。
其中，下支架5与底座4的限位机构，为一护板511；下支架5通过固定轴51铰接于底座1上，护板511也同时铰接于底座1上，且护板511覆盖于下支架5外侧，并伸出于下支架5外，向底座1方向进行适当延伸，在打开下支架5时，延伸的护板511会抵触到底座1，使下支架5打开到一定的角度后不能再继续打开，由此限制LED灯组的角度，为人们提供合理角度的照明，同时也便于人们使用。
上支架4与LED灯组3的限位机构，为两块盖板，其中一块盖板为上盖板311，覆盖于LED灯组3上，另一块盖板为下盖板312，覆盖于上支架4上；上支架4通过连接轴31铰接于LED灯组3上，所述两块盖板也同时铰接于连接轴31上，且上盖板311覆盖于LED灯组3上，并延伸于LED灯组3外，向 上支架4方向延伸；下盖板312覆盖于上支架4外侧，并伸出于上支架4外，向LED灯组3方向进行适当延伸，在打开LED灯组时，延伸的两块盖板311、312会相互抵拢，使LED灯组3打开到一定的角度后不能再继续打开，从而保证了LED灯组打开的角度，为人们提供合理角度的照明，人们使用时不比调整角度就可以直接使用，使用更加方便。
下支架5和上支架4之间的限位机构，为限位板。其中，覆盖于上支架4的限位板为上限位板411，覆盖于下支架5的限位板为下限位板412；上限位板411覆盖于上支架4上，并延伸于上支架4外，向下支架5方向延伸；下限位板412覆盖于下支架5外侧，并伸出于下支架5外，向上支架4方向进行延伸，在打开支架时，延伸的两个限位板411、412会相互抵拢，使支架打开到一定的角度后不能再继续打开，控制支架打开的角度。
结合图3所示，本发明还有一个特点是：将下支架5和上支架4交错设置，使下支架5设置于上支架4的外侧，并通过铰轴41连接在一起，在收拢时，上支架4能够基本收拢于下支架5之间的空位内，以有效地减少收拢体积。
在另外一种实现方式中，也可以将LED灯组3设置其宽度小于上支架4的间距，这样在收拢时，可以将能够LED灯组3完全收拢于上支架4之间，既能保护LED灯组，又能够减少收拢体积和空间，便于人们携带及使用。
总之，本发明通过支架与底座、LED灯组之间设置限位机构，控制支架、LED灯组的张开角度，有效地控制支架及LED灯组的打开角度，从而能够为人们提供合理的照明角度，便于LED灯组发挥最有效的照明效果，以保护人们的视力。
而且，该LED护眼灯结构简单，便于收拢，占用体积小，易于放置，便于办公及家庭使用。
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作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
