PURPOSE: A lighting device is provided to easily discharge heat from a light source unit to outside by forming a vent hole at the lower side of a lamp post. CONSTITUTION: A lamp(100) emits light delivered from a lamp post to outside. The lamp post comprises a base(370). The lamp post is composed of a first lamp post(310) and a second lamp post(330). The first lamp post comprises a light route changing means(390). The light route changing means changes a route of light from a light source unit(350). The light source unit comprises a light emitting diode. The light route changing means transfers the light emitted from the light source unit to a reflector(110). The reflector reflects the light and emits the light to outside. A diffusing plate diffuses the reflected light. |
