本論文之目的在探討高壓鈉燈之調光特性，探討之內容主要包括輸入功率
、燈管功率、燈管電壓、燈管電流、燈管之等效電阻、燈管所產生之光通
量、光效率與系統之電效率等。文中以半橋式串聯共振電路為架構，將高
壓鈉燈操作在高頻24kHz、DC155V，除理論分析與電路模擬外，並以市售
之高壓鈉燈SYLVANIA LU 100W/MED為例，實際量測高壓鈉燈之調光特性。
調光之方式採調頻調光與調壓調光兩種，經由電路之分析、模擬與實測，
評估兩種調光控制之優劣。由實驗之量測結果發現，調光時高壓鈉燈燈管
之等效電阻會隨著燈管功率之調降而小幅降低，燈管之光通量、光效率與
系統之電效率均在額定功率時達到最高，分別為9940lm，99lm/W與91.8%
，並隨著燈管功率之調降而降低。調頻調光之功率由32W調至100W；調壓
調光之功率由42W調至100W。

The purpose of this thesis is to study the characteristics of
high pressure sodium (HPS) lamp for dimming control. It mainly
contains the following items: input power, output power, lamp
voltage, lamp current, lamp equivalent resistance, lamp luminous
flux, lamp luminous efficiency and system electrical efficiency,
The main circuit is constructed by a half-bridge with series
resonant inverter, Dimming operating is achieved by adjusting
switching frequency and input DC voltage of the inverter. A
prototypical circuit for the SYLVANIA LU 100W/MED HPS lamp is
implemented and the experimental results are used to verify the
theoretical predication and the computer simulation. In
addition, the experimental results had shown that its lamp
equivalent resistance could be varied with adjusting lamp power,
The lamp luminous flus, lamp luminous efficiencyt, system
electrical efficiency are 9940lm, 99lm/W and 91.8% respectively
at nominal lamp power. The output power of HPS lamp could be
regulated from 32W to 100W by adjusting switcheng frequency and
from 42W to 100W by adjusting input DC voltage of the inverter.
