The present invention relates to an LED lamp for a streetlight and, more specifically, to an LED lamp for a streetlight capable of being installed around a sidewalk. The present invention forms a plurality of division light source plates having LED light sources installed inside the body of the LED lamp. Each division light source plate comprises various angles and is controlled. The present invention is provided to control and change an irradiation range and an irradiation angle without a shielding plate used in a lamp for a streetlight, thereby minimizing the damage caused by the light of the streetlight according to an optimal shielding and irradiation range by considering the feature and the situation of a road and an adjacent area through the control of the irradiation angle or the change for the irradiation range when an agricultural land, a pen, or a house exists in the adjacent area of the streetlight. The present invention is provided to maintain the uniformity factor for the road and to prevent the fatigue of a driver caused by the uniformity degradation, thereby previously preventing a safety accident. |
