具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1-2，本发明提供一种技术方案：一种带有散热功能的LED电梯灯，包括电梯顶板1，电梯顶板1顶部中心处设置有固定块2，固定块2的顶部设置有内轴承圈3，内轴承圈3的顶部设置有外轴承圈5，且内轴承圈3置于外轴承圈5的内腔，内轴承圈3通过钢珠4与外轴承圈5转动连接，外轴承圈5的左右两侧底部均设置有扇叶6，电梯顶板1的底部中心处设置有吸热版7，吸热版7的顶部设置有散热板701，散热板701顶部从左至右依次设置有三组导热棒702，散热板701的底部通过相匹配的卡块703、卡槽与散热板701的内腔活动连接，导热棒702置于吸热版7的一端左右两侧均设置有导热块704，导热块704的表面均匀的设置有散热鳍705，吸热版7的左右两侧均通过连接杆7设置有LED灯9，LED灯9的外部设置有保护罩10，保护罩10的底部设置有折射层11，折射层11的内腔设置有折射镜12，折射层11的左右两侧与保护罩10的左右两侧均设置有相匹配的通孔13，电梯顶板1上设置 有与扇叶6相对应的通风槽14。
其中，通风槽14的内腔顶部设置有过滤网，且通风槽14的长度与保护罩10的长度相同，避免风从别的地方吹出，在冬天造成电梯内的环境处于低温状态；每组导热棒702上共设置有四组导热块704，且每组导热块704上均设置有四组散热鳍705，可快速有效的将LED灯9产生的热量吸收散发；保护罩10为透明亚克力板制成，透光光性强使用寿命长，且保护罩10与折射层11之间设置有贴合层，安装更方便；内轴承圈3的顶部左右两侧均设置有限位块，且限位块的长度小于钢珠4的直径，避免内轴承圈3从外轴承圈5上脱落。
工作原理：LED灯9通过外接电源开启后，吸热板7会将LED灯9产生的热量吸收，吸热板7将热量传输到散热板701，而散热板701通过导热棒702上设置的导热块704与散热鳍705将热量散发到通风槽14，而通过电梯的上下移动产生的风力使扇叶6开始转动，当电梯向上移动时风力会带动扇叶6逆时针转动进行吸风将通风槽14内的热量吸出并散发，当电梯向下移动时风力会带动扇叶6顺时针转动将热量通过通孔13吹出。
尽管已经示出和描述了本发明的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由所附权利要求及其等同物限定。
