PURPOSE: A lamp for a sport ground using a light emitting diode lamp which reduces power consumption is provided to improve durability by radiating heat using a circulation refrigerator. CONSTITUTION: An inlet hole(120) with a reflector(130) is formed in a main body(10) using a partition(110). The light emitting diode lamp(20) comprises a cooling fin(220) including a light source on the rear side and a LED device(210) which is the light source. A circulation refrigerator(30) expedites the cooling of the cooling fin and is located behind the LED lamp. A controller(40) controls the power supply to the LED lamp and the circulation refrigerator. The cooling fin has a protrusion on the surface and a space part on the center part. The cooling fin of the light emitting diode lamp and a cooling pipe(320) is connected to the circulation refrigerator. |
