摘　　要：无极灯由于具有高效节能、长寿命的特点,成为目前研究的热点。为了研究提高无极灯光效的途径,采用实验研究和理论分析的方法,研究了放电功率、放电频率、泡体形状和荧光粉对无极灯光照度和泡体表面温度的影响。研究结果表明:在所研究的范围内,无极灯的光照度和泡体表面温度均随着功率的增加而增加;光照度随工作频率的增加先增加后减小,在2.4MHz左右达到最大值;3种不同形状泡体的光照度由大到小顺序为拍型、梨型、橄榄型;荧光粉不仅能大大提高无极灯的光照度,而且能降低无极灯泡体的表面温度。这些研究结果对工业上优化无极灯的放电参数、选择合适的泡体形状和荧光粉具有重要的指导意义。In order to investigate the way to improve the efficacy,we experimentally researched and theoretically analyzed the effect of discharge power,operating frequency,bulb shape and phosphor powder on illuminance and bulb surface temperature.The results show that,illuminance and surface temperature increase with discharge power increasing;illuminance first increases then decreases with operating frequency and has a maximum at about 2.4 MHz;the discretion order of the three different shapes is clap shape pear shape olive shape;and phosphor powder not only increases the efficacy greatly but also decreases the bulb surface temperature.The results can be used for optimization of discharge parameters and selection of bulb shape and phosphor powder.
