Abstract: The present invention discloses is an easy heat-dissipating lamp structure, comprising an outer shell. Inside the upper half space of the outer shell, there are multiple rib plates formed in the direction from top to bottom, so that multiple vertical gaps are formed. A heat dissipator is held inside the lower half space of the outer shell, leaning and fixed on the lower edge of the rib plates. The bottom face of the heat dissipator is attached with a light emitting plate. The heat generated by the light emitting plate is received by the heat dissipator and is discharged through the vertical gaps between the multiple rib plates.

Abstract: The present invention discloses a joinable lamp structure, which is made by joining two neighboring lamps through a joining component. A side cap is used to cover the exposed ends of the lamps. After the assembly, the present invention can be embedded inside the mounting slot of the ceiling or suspended below the ceiling.
