PURPOSE: A tube shape led lamp capable of effectively dissipating the heating of LED elements to the outside is provided to move a heat sink which is normally formed on the outside of a tube to the inside of the tube, and to install a vent on the upper end of the tube, thereby facilitating the dissipation of heat which is generated by LED elements. CONSTITUTION: A tube-shaped LED lamp comprises a long pipe-shaped tube(30); a heat sink(21) which is equipped inside the tube; and a substrate(22) which is mounted with an LED chip on the lower part of the heat sink. The tube is manufactured by extrusion-molding. The extrusion-molded tube is provided additionally with a ventilation hole(31), which is formed by boring or cutting, on the upper end. The tube is provided with a connection cap(20). The connection cap is also formed with a ventilation hole. |
