Abstract
The invention relates to an uncapping device of a lamp and the lamp. The uncapping device of the lamp is used to fix a lamp cover of the lamp. The lamp cover is made of a magnetic material. The uncapping device of the lamp is arranged at the bottom end of a reflector, and comprises a plurality of sets of magnetic assemblies which attract the lamp cover. Each magnetic assembly comprises a permanent magnet and a fixing assembly which fixes the permanent magnet to the bottom of the reflector. The size of the permanent magnets of a part of the magnetic assemblies in the sets of magnetic assemblies is smaller than that of the permanent magnets of the other part of the magnetic assemblies in the sets of magnetic assemblies. According to the uncapping device of the lamp and the lamp provided by the invention, the magnetic assemblies attract the lamp cover through the permanents. When the lamp cover is opened, the lamp cover is pulled by the permanent magnet in a small size through an external force to separate the lamp cover from the permanent magnet so as to open the lamp cover. The uncapping device and the lamp are simple in structure and convenient and rapid, and can be realized without tools. The uncapping device and the lamp are simple and easy, time-saving, labor-saving and convenient to install.
