工作原理：当用户不需要使用LED台灯时，用户逆时针转动第三转杆，带动第三皮带轮逆时针转动，通过第二平皮带的作用带动第四皮带轮逆时针转动，从而使第二转杆逆时针转动，带动第二皮带轮逆时针转动，通过第一平皮带的作用带动第一皮带轮逆时针转动，从而带动第一转杆逆时针转动，齿轮也随之逆时针转动，因为齿轮与齿条啮合，所以齿轮逆时针转动带动齿条向上移动，从而带动滑块向上移动，从而使环形移动板向上移动，当环形移动板向上移动到一定位置后，由于磁力的作用第一磁铁吸引第二磁铁向上移动，第二磁铁向上移动抽出第一凹槽内的薄膜，从而封闭LED灯，防止灰尘进入，此时用户停止转动第三转杆。当用户需要使用LED台灯时，用户顺时针转动第三转杆，带动第三皮带轮顺时针转动，通过第二平皮带的作用带动第四皮带轮顺时针转动，从而使第二转杆顺时针转动，带动第二皮带轮顺时针转动，通过第一平皮带的作用带动第一皮带轮顺时针转动，从而带动第一转杆顺时针转动，齿轮也随之顺时针转动，因为齿轮与齿条啮合，所以齿轮顺时针转动带动齿条向下移动，从而带动滑块向下移动，从而使环形移动板向下移动，使第二磁铁向下移动，使第二磁铁与第一磁铁分离，当环形移动板向下移动到初始位置后，用户停止转动第三转杆，然后拿起第二磁铁，将薄膜放入到第一凹槽内，再将第一磁铁放下。
因为还包括有凸块，环形移动板左右两侧对称焊接连接有凸块，滑块左右两侧对称开有第三小孔，凸块形状为长方体形，第三小孔形状为长方体形，凸块与第三小孔配合，当需要将将环形移动板安装在滑块上时，用户将凸块插入到第三小孔内，当需要拆卸环形移动板时，则将移动环形移动板将凸块拔出第 三小孔。
因为还包括有小板、球体和第二支杆，滑块左右两侧对称胶接连接有小板，小板上开有第四小孔，小板位于第三小孔内，环形移动板左右两侧对称焊接连接有凸块，凸块上胶接连接有第二支杆，第二支杆上焊接连接有球体，球体与第四小孔配合，当需要将将环形移动板安装在滑块上时，用户将凸块插入到第三小孔内，并使球体进入到第四小孔内，可以增加环形移动板的稳定性，当需要拆卸环形移动板时，则将移动环形移动板将凸块拔出第三小孔，使球体拔出第四小孔。
因为还包括有橡胶垫，灯座底部粘接连接有橡胶垫，橡胶垫形状为圆柱体形，橡胶垫的高度为1厘米，橡胶垫形状与灯座的形状相同，橡胶垫的材质为人工合成橡胶，可以防止灯座刮坏家具。
因为灯罩左右两侧均匀地开有条形凹槽，条形凹槽的深度为灯罩厚度的一半，灯罩前后两侧均匀地开有三角形凹槽，三角形凹槽的大小逐次减小，三角形凹槽的厚度的一半，可以增加LED灯的散热效果，还可以增加美观性。
(3)有益效果
本发明可以有效地防止灰尘进入带LED灯内，当用户不需要使用时，用户逆时针转动第三转杆，齿轮也随之逆时针转动，从而带动齿条向上移动，从而使环形移动板向上移动，当环形移动板向上移动到移动位置后，由于磁力的作用第一磁铁吸引第二磁铁向上移动，第二磁铁向上移动抽出第一凹槽内的薄膜，从而封闭LED灯，防止灰尘进入，当用户需要使用LED灯时，则顺时针转动第三转杆。
