PROBLEM TO BE SOLVED: To provide a lamp system equipped with a stabilizer which can offer stabilized reference voltage without influenced by the fluctuation and temperature at resistor manufacturing process, and can prevent sharp deviation of the reference voltage at light adjusting control time, and light adjusting and on/off controlling are achieved with one terminal. SOLUTION: The lamp system contains following items: a power source to supply lamp driving source, a half bridge converter to input the lamp driving source to the lamp side a lamp part to emit light using resonance circuit by input of lamp driving source, a stabilizer to control the lamp driving current for the lamp part, a reference voltage forming part of the stabilizer outputs the reference voltage stably without influenced by temperature and the fluctuations at resistor manufacturing time. The impact is suppressed which is received by the total lamp system by the variation of lamp illumination degree, by time delay control of the lamp driving current following in the lamp for controlling the illumination degree. |
