A method for adapting an LED lamp tube to a fluorescent lamp tube holder, an LED lamp tube holder and an illumination device. The LED lamp tube holder comprises an adaptation bracket and a lamp tube holding clip which is connected to the adaptation bracket. The lamp tube holding clip has a circular-arc cylindrical holding surface, thereby being clamped to the outer wall of a light transmission tube of the LED lamp tube. A cylindrical pin which axially extends from the LED lamp tube holder along the light transmission tube is arranged on the adaptation bracket. The shape of the pin is the same as that of an electrically-conductive pin of the fluorescent lamp tube, thereby enabling the LED lamp tube holder to be arranged in the fluorescent lamp tube holder. The LED lamp tube can be arranged on the basis of the original LED lamp tube holder.

A magnetic scrubber assembly and its design method for cleaning the wall-glass of an aquarium are provided. The center of gravity of the internal scrubbing component is designed underneath its the geometrically horizontal central axes. A product of length Lp from a center of gravity Pp of an internal scrubbing component to a lowest part and the center of gravity P of the internal scrubbing component is smaller than a product of a length Lf from equivalent function point Pf of buoyancy F such that the internal scrubbing component is received to its lowest part. This ensures that the internal scrubbing component can erect automatically after it is lied down. When the internal scrubbing component breaks away from the control of a hand-held scrubbing component, the internal scrubbing component can sink upright, and the magnetic scrubber assembly is restored to the normal operation condition.
