This utility model relates to the field of LED lighting technology, specifically to an assembly-type maintenance and replacement device for LED lights, comprising: a lamp holder; a slot formed on the side wall of the lamp holder; a lampshade structure mounted on the lamp holder, the lampshade structure including a lampshade body, the lampshade body being movably mounted on the lower side of the lamp holder, a movable groove formed on the side wall of the lampshade body, a slider provided on the inner wall of the movable groove, and a guide groove formed at the inner edge of the top surface of the lampshade body. This utility model, by forming a guide groove at the inner edge of the top surface of the lampshade body, increases the opening space at the upper end of the lampshade body. When installing the lampshade body, it is not necessary to precisely align the lampshade body with the lamp holder, increasing the installation tolerance of the lampshade body. Furthermore, when the guide groove abuts against the bottom surface of the lamp holder, it guides the lampshade body to cover the outer side of the bottom surface of the lamp holder, achieving convenient installation of the lampshade body at the bottom of the lamp holder and improving the practicality of the device.
