PURPOSE: A lighting device is provided to improve light efficiency by providing a structure which releases heat from a light source. CONSTITUTION: A lighting device comprises a lamp(100) and a lamp post. The lamp is connected to the lamp post. The lamp emits light to the outside from the lamp post. The light is created from a light source part(350) arranged inside the lamp post. The light emitted from the light source part is transferred to the lamp through the lamp post. The lamp comprises a second light transmitter(430). The second light transmitter reflects light reflected from a first light transmitter arranged inside the lamp post to the outside. A diffusing plate diffuses the light reflected from the second light transmitter. |
