High pressure discharge lamp lighting device and luminaire |
摘要 |
<p>A high pressure discharge lamp lighting device, includes: a DC/DC converter for converting a power source voltage of a DC power source into a desired DC voltage and stably lighting a high pressure discharge lamp; a DC/AC inverter for inverting the DC voltage into an AC voltage; and a starting pulse generating circuit for generating a high voltage required for the start-up of the high pressure discharge lamp. Further, the high pressure discharge lamp lighting device includes a lighting state decision unit for deciding a lighted/unlighted state of the high pressure discharge lamp; and an operating state switching control unit for switching the operating state of at least one of the DC/DC converter, the DC/AC inverter, and the starting pulse generating circuit to another operating state, depending on a predetermined operation phase out of the start-up, stable lighting and power interrupt phases of the high pressure discharge lamp.</p> |
