(22) The bottom cover 8813 has a bottom connector 8812 for detachably connecting to the base connector 8811.

(23) When users want to use diffusion illumination, the top cover is removed and the light passing cover is inserted.

(24) When users want to use light beam mode for a focused object, the light passing cover is replaced with the lens.

(25) The bottom cover is fixed to the closet first. When necessary, the module of the top cover and the base plate is attached to the bottom cover.

(26) The receiver socket is used for receiving power used by the LED module of the light source plate.

(27) In some embodiments, the bottom cover has a screw hole 8815 for fixing to a closet, the base plate 8808 connected with the top cover 8801 is attached to the bottom cover 8806 when necessary.

(28) The LED module 8805 receives a power supply from a connecting wire 8816 inserted into the receiver socket 8809.

(29) Users may attach screws or nails or plugging structures or sticking tape to fix the bottom cover to the closet first.
