The main function of a desk lamp is to provide lighting, which is convenient for reading, studying and working. With the continuous development of the appearance, shape and function of desk lamps, there are cover-type dust-proof structures on the market (a cover is provided on the outside of the desk lamp, and the cover can be removed and cleaned at any time), assembly-type dust-proof structures (a special dust-proof assembly is provided in the desk lamp structure to effectively isolate dust and other debris outside the desk lamp), magnetic dust-proof structures (some desk lamps use magnetic technology to separate the part with stronger magnetic force from the base for easy cleaning), sliding dust-proof structures (a sliding device is provided between the desk lamp base and the bracket to isolate dust from the outside), and fan-type dust-proof structures (a built-in fan can absorb dust and other debris, filter them and then discharge them, thereby achieving the purpose of dust prevention).
