摘要： A lighting apparatus of high intensity discharge lamp comprises a DC power source, a series connection of a first and a second transistors; a series connection of a first and a second capacitors connected in parallel with the series connection of the transistors; a series connection including at least an inductor and a discharge lamp connected between a connection point of the transistors and another connection point of the capacitors, and a control circuit for switching on and off of the transistors so as to supply electric power to the discharge lamp. A voltage of the first capacitor is set to be higher than that of the second capacitor corresponding to the capacitances of the first and second capacitors. Thus, the pulse height in negative or positive phase of the rectangular alternating voltage applied to the discharge lamp can be increased without increasing the output voltage from the DC power source.

摘要： A discharge lamp lighting device includes: a direct current power supply circuit that outputs direct current power; an inverter circuit that converts the direct current power, which is outputted by the direct current power supply circuit, into alternating current power, and supplies the alternating current power to a discharge lamp; a control circuit that controls a frequency of an output of the inverter circuit (operation frequency); and a starting detection circuit that detects beginning (starting) of a discharge in the discharge lamp. The control circuit operates in a starting improvement mode, in which the operation frequency is lowered than an operation frequency in a lighting mode, during a predetermined time from when the starting of the discharge lamp is detected by the starting detection circuit 4 during a no-load mode. Thereafter, the control circuit shifts to the lighting mode in which lighting of the discharge lamp is maintained. In such a way, the discharge lamp can be smoothly shifted to stable lighting.
