PURPOSE: A lighting device for the installation of a street lamp is provided to prevent the lowering of luminance since all lights incident on a reflector are reflected to a road without additional reflection paths. CONSTITUTION: A light emitting apparatus(100) generates light by driving power provided from the outside. The light emitting apparatus is connected to the sensor-device for sensing brightness of the surroundings. The light emitting apparatus is formed in a reflecting cover(200). A reflector(300) is installed in the reflecting cover with covering the light emitting apparatus. The reflector comprise a vertical surface(310) formed vertically to an inlet(210) and a curved surface formed roundly in order to cover the light emitting apparatus. |
