Abstract
A combinational inset lamp exempt from a shielding cylinder comprises a light-source body. The light-source body is covered by an insulation cover. An extension cover replaceable is provided at the top of insulation cover. An outer disk cover spirally removable and replaceable is provided outwards and transversally around the outer circumference of the lower part of insulation cover. At least opposite two sides of the outer circumferential wall of insulation cover are respectively formed outwards with an elastic clamping flake. The elastic clamping flake is removable and flexible so that the outer disk cover and the elastic clamping flake may work with each other to directly wedge the lamp onto the ceiling. Thus, the lamp that may be provided without any shielding cylinder is removable and replaceable conveniently for achievement of the advantages of carbon decrease, energy saving, and environmental protection.
