PURPOSE: A shading device for a lamp head of a streetlight is provided to adjust freely a shading range by variably fixing a shading plate to a fixing plate as necessary. CONSTITUTION: Shading plates (20,20') and fixing plate(10) are formed with a metal substance. The shading plate is fixed to the fixing plate by using a combination screw. A cutting part(11) is formed in the inside of the fixing plate. An insertion part(21) is formed at the shading plate so as to prevent the interference between the shading plate and a lamp. The shading plate is formed to interrupt the diffusion of the light of the lamp to a backside of a lower side of the lamp head. |
