中文摘要 | 本文針對商用 LED 平板燈的調光設備,進行額定功率之100%、75%、 50%、25%、10%、0%的電氣特性測量,觀察 LED 燈具在調光過程之功率因 數、電流總諧波失真、轉換效率的變化。10組平板燈的測量結果,顯示額定 功率下的電氣特性都符合安規,但調光至額定功率50%以下,很多電氣特性 不符合安規。再加上商用 LED平板燈額定功率都設計在40W以下,雖可以操 作在市電230V,其功率因數、電流總諧波失真、轉換效率都比操作在市電 120V 差。 |
英文摘要 | This paper measures the electrical characteristics of 100%, 75%, 50%, 25%, 10%, and 0% of the rated power of commercial LED panel lights, and observes the power factor, current total harmonic distortion, and conversion efficiency. The measurement results of 10 sets of LED panel lights show that the electrical characteristics at rated power all comply with safety regulations, but when dimmed to less than 50% of rated power, many electrical characteristics do not comply with safety regulations. In addition, the rated power of commercial LED panel lights is designed to be below 40W. Although they can operate on 230V, their power factor, current total harmonic distortion, and conversion efficiency are worse than those operating on 120V. |
