PURPOSE: An LED lamp which is buried in a ceiling and includes a superior heat emitting structure is provided to quickly and efficiently transfer hot air to a heat emitting object through a heat emitting case, thereby obtaining superior heat emitting effects. CONSTITUTION: A vertical cutting unit is formed in a mounting ring(12) of a cover object(10). A separate grabbing piece is fixed to the vertical cutting unit. A placing groove(22) is formed on the upper surface of a heat emitting case(20). Radial insertion protrusions are formed on the placing groove. The grabbing piece includes an inner bent protrusion and an outer bent protrusion. The outer bent protrusion faces the outside of a placing ring. The insertion protrusions are inserted into between heat emitting fins respectively. |
