 Abstract
Conventional streetlight with the not-adjustable light distribution characteristic is generating light pollution such as glare, damage to the crops and disturbed sleep, because beam of streetlight is not distributed evenly according to the surrounding areas and road conditions. In this paper, we proposed the new structure LED streetlight controlled light irradiation angle according to the surrounding areas and road conditions. Proposed LED streetlight are available to the adjustable light distribution characteristic using the half-circle angle control device. Result of measurement and simulation, beam angle is made available to control at least from up to , average illumination exceeded 15% of KS regulation and overall uniformity exceeded more than 50% of KS regulation. the Developed large capacity LED streetlight luminaire is considered to minimize glare and light pollution and optimize uniformity ratio of illuminance.
