PURPOSE: A lamp is provided to improve a lifespan and performance by effectively radiating heat, which is generated at inner space, to outside and uniformizing the direct and side brightness of light. CONSTITUTION: An external diameter increases from one end of a socket part(100) to the lower side of an axial direction and the socket part comprises an upper side wall part(200) and a lower side wall part(300) including a control part(210), which is electrically connected to the power supplying terminal, inside. Heat generated inside is discharged to outside with heat discharging holes(220, 320). |
