Method for identifying rated power of HID lamp |
摘要 |
A method for identifying a rated power of a HID lamp includes the steps of: outputting a first driving signal and a second driving signal to drive the HID lamp in order, and calculating a first electric characteristic variation of the HID lamp; and identifying the rated power of the HID lamp according to the first electric characteristic variation and a first default value. |

1. A method for identifying a rated power of a high intensity discharge (HID) lamp, the method comprising the steps of:
(a) outputting a first driving signal and a second driving signal to drive the HID lamp in order, and calculating a first electric characteristic variation of the HID lamp; and (b) identifying the rated power of the HID lamp according to the first electric characteristic variation and a first default value; wherein the step (a) comprises: outputting the first driving signal to drive the HID lamp; outputting the second driving signal to drive the HID lamp at a first predetermined time, and recording a first electric characteristic, generated by the HID lamp in response to the second driving signal; and recording a second electric characteristic, generated by the HID lamp in response to the second driving signal at a second predetermined time, and calculating the first electric characteristic variation between the first electric characteristic and the second electric characteristic. |
