摘要
近年来,LED灯以其节能、高效、寿命长等特点被广泛应用,已开始应用于体育照明。为研究LED灯的电压特性,对7款LED灯进行了试验,测试在电压变化时LED灯的电流谐波畸变率及照度值等的变化情况。通过数据分析可看出,电压在一定范围内变化时,LED灯的照度基本不变,对谐波的影响也有限,这种较稳定的电压特性使得LED灯更适合应用于体育照明。根据分析结果,本文对JGJ 354—2014《体育建筑电气设计规范》进行了补充。
In recent years,LED lamp has been widely used for its energy saving,high efficiency and longlife,especially in sports lighting. In order to study the voltage characteristics,7 different LED lamps were tested to test the current harmonic distortion rate and illumination value of LED lamps under voltage changes. Through the data analysis,we can see that when the voltage changes in a certain range,the illumination of the LED lamp is basically unchanged,and the influence on the harmonic is limited. This stable voltage characteristic makes LED lights more suitable for sports lighting. According to the analysis results,this paper finally makes a supplement to JGJ 354—2014.
