| 摘 要： | 分析了调频调光法的工作原理，并采用自行设计的电子线路实现了LVD感应无极光源的调频调光．测试了在这种调光方法下工作的光源的光电特性，分析了调频调光的稳定性和可靠性．作为对比，对调压调光法下灯的性能也进行了测试．实验表明，LVD感应无极光源采用调频调光法时，调光范围为100％到35．5％，在整个调光范围内色温和显色指数分别有3．8％和4．7％的改变．

| Abstract: | The principle of the frequency-control dimming is analyzed and the dimming of the LVD induction Electrodeless Lamp is achieved by the circuit designed by ourselves with this principle.The electrical and photometric performances of the light source during dimming with this method are measured as well as the stability and reliability.With the purpose of comparison ,lamp's performances are measured when the voltage-control dimming is used.Experimental results show that,the dimming range is from 100% to 35.5% when frequency-control dimming is used in the LVD induction Electrodeless Lamp and the color temperature and the color rendering index change by 3.8% and 4.7% respectively when dimming. |
