The invention discloses a novel energy-saving
LED lamp which comprises a shell and a lamp body. The shell is embedded in a roof, the lamp body is fittingly connected with the shell, an
insertion groove is formed in the middle of the bottom surface of the shell, a first driving groove is formed in the middle of the top wall of the
insertion groove, a second driving groove is formed in the right side of the top wall of the
insertion groove, and a third driving groove is formed in the shell, and is particularly formed in a location which is positioned above the first driving groove and is positioned on the left side of the second driving groove. The novel energy-saving
LED lamp has the advantages that the lamp body can be firmly locked; the lamp body can be firmly locked and can be simultaneously powered on during mounting; the lamp body can be powered off and simultaneously can be unlocked during detaching, accordingly, the lamp body mounting and detaching efficiency can be greatly improved, the lamp body can be conveniently detached and changed after being damaged,
electric shock accidents can be effectively prevented in lamp body mounting and detaching procedures, and the life safety of people can be guaranteed; the lamp body can be mounted and detached by the aid of a single motor, and accordingly the production cost can be saved.
